BENEFITS OF LED

Warehouse - After LED Installation
LED's offer the most efficient way of illumination and lighting, with an estimated energy efficiency of 55%-80% when compared to traditional lighting and conventional light bulbs. This means that the majority of the electrical energy is converted to light, rather than being lost and converted into other forms of energy such as heat.
Because the long life span of LED lights, you can achieve significant energy savings also when it comes to maintenance and replacement due to the long operational life times of LED lighting.
LED bulbs and diodes have an outstanding operational life time expectation of 50,000+ hours. This means if you leave the LED fixture on for 12 hours per day it would take over 10 years before you would have to replace the LED bulb.
LED lights contain no toxic materials and are 100% recyclable. The long operational life time span mentioned above means also that one LED light bulb can save material and production of 25 incandescent light bulbs.
LEDs are extremely durable and built with sturdy components that are highly rugged and can withstand even the roughest conditions, including construction or manufacturing sites. LED lights are resistant to shock, vibrations and external impacts and make great outdoor lighting systems for rough conditions and exposure to weather, wind, rain or even external vandalism, traffic related public exposure.
Zero UV Emissions
LED illumination produces little infrared light and close to no UV emissions. Because of this, LED lighting is highly suitable not only for goods and materials that are sensitive to heat due to the benefit of little radiated heat emission, but also for illumination of UV sensitive objects or materials.
LEDs can be combined in any shape to produce highly efficient illumination. Individual LEDs can be dimmed, resulting in a dynamic control of light, color and distribution.
Operational in Extremely Cold or Hot Temperatures
LED are ideal for operation under cold and low outdoor temperature settings. For fluorescent lamps, low temperatures may affect operation and present a challenge, but LED illumination operates well also in cold settings, such as for outdoor winter settings, freezer rooms etc.
LED is designed to focus its light and can be directed to a specific location without the use of an external reflector, achieving a higher application efficiency than conventional lighting. Well-designed LED illumination systems are able to deliver light more efficiently to the desired location.
LED lights brighten up immediately when powered on, which has great advantages for infrastructure projects such as e.g traffic and signal lights.
LED lights can switched off and on frequently and without affecting the LED’s lifetime or light emission. In contrast, traditional lighting may take several seconds to reach full brightness, and frequent on/off switching does drastically reduce operational life expectancy.

Even though the Casio XJ-UT310WN projector measures 16.5 inches long by 13 inches wide by 6 inches high, it was a built in 16 watt speaker that fills even the largest rooms with sound.
The wireless LAN adapter is perfect for presentations from a computer or laptop. The HDMI, USB, and component inputs allow you to easily send video or images to the projector from any device.
Quick start mode allows the projector to reach full brightness in only 8 seconds, and it instantly turns off without requiring a cool down period like most projectors.
The Casio projector rests nicely on a table top, bookshelf, or other sturdy stand. This works nicely for small areas where a normal projector couldn't fit. It can also be wall or ceiling mounted with the optional mounting device.


Assuming that the cloud server can handle the processing load and the communication latency is negligible, would it be possible to implement a vision system with only cameras as the input devices?”
Cloud Vision Pro: A Vision System with Only Cameras
Vision systems are applications that use computer vision techniques to perform tasks such as object detection, face recognition, scene understanding, and more. Vision systems typically require a combination of input devices, such as cameras, sensors, and scanners, and processing devices, such as computers, servers, and cloud platforms.
However, what if we could simplify the vision system architecture by using only cameras as the input devices, and offloading the processing to a cloud server? This is the idea behind Cloud Vision Pro, a hypothetical vision system that leverages the power of cloud computing and the ubiquity of cameras.
The feasibility of Cloud Vision Pro depends on two main factors: the processing capacity of the cloud server, and the communication latency between the cameras and the server. Let us examine each of these factors in detail.
The processing capacity of the cloud server determines how fast and how accurately the vision system can perform the desired tasks. The processing capacity depends on the hardware specifications, such as CPU, GPU, RAM, and storage, as well as the software frameworks, such as TensorFlow, PyTorch, OpenCV, and more.
The processing capacity also depends on the number and complexity of the tasks, the number and resolution of the cameras, and the amount and format of the data. For example, a task that involves detecting multiple objects in a high-resolution video stream from multiple cameras would require more processing capacity than a task that involves recognizing a single face in a low-resolution image from a single camera.
The processing capacity of the cloud server can be scaled up or down according to the demand and the budget. Cloud platforms, such as AWS, Azure, and Google Cloud, offer various options and services for cloud computing, such as virtual machines, containers, serverless functions, and more. These options and services allow the users to customize and optimize the processing capacity of the cloud server according to their needs and preferences.
The communication latency between the cameras and the server determines how fast and how reliably the vision system can receive and send the data. The communication latency depends on the network infrastructure, such as bandwidth, throughput, and protocol, as well as the network conditions, such as congestion, interference, and noise.
The communication latency also depends on the amount and format of the data, the number and location of the cameras, and the security and privacy requirements. For example, a data stream that involves sending high-resolution video frames from multiple cameras located in different regions would require more bandwidth and incur more latency than a data stream that involves sending low-resolution image snapshots from a single camera located in the same region.
The communication latency between the cameras and the server can be reduced and improved by using various techniques and technologies, such as compression, encryption, caching, edge computing, and more. These techniques and technologies allow the users to minimize and mitigate the impact of the communication latency on the performance and quality of the vision system.
In conclusion, Cloud Vision Pro is a vision system that uses only cameras as the input devices, and offloads the processing to a cloud server. The feasibility of Cloud Vision Pro depends on the processing capacity of the cloud server, and the communication latency between the cameras and the server. These factors can be adjusted and optimized by using various options, services, techniques, and technologies offered by cloud platforms and network providers. Cloud Vision Pro is a potential solution for simplifying and enhancing the vision system architecture and functionality.

What's the main function of a Variable ND Filter?
A Variable ND (Neutral Density) Filter is all about controlling light. It's super handy for managing how much light gets into your camera. You can adjust its density to suit various lighting situations, which is great for pulling off creative effects like motion blur, even when it's really bright out.
How do you change the strength of a Variable ND Filter?
To adjust a Variable ND filter, you just need to rotate its two polarizing layers. This is done by turning the outer ring, which changes the filter's density. This way, you can control the light passing through your lens, adapting easily to whatever lighting conditions you're facing.
Can a polariser and a Variable ND Filter be used concurrently?
While it's technically feasible to stack a polariser and a variable ND filter, it's generally advised against. Both filters influence the polarisation of light, and using them together can lead to undesired effects such as uneven polarisation, colour shifts, and diminished image quality. For combined effects, a singular filter that integrates both polarising and ND features is recommended for more consistent outcomes.
What distinguishes an ND filter from a variable ND filter?
A standard ND (Neutral Density) filter offers a fixed level of light reduction, consistently dimming the scene. In contrast, a Variable ND filter provides adjustable light reduction through the rotation of its outer ring, giving you more flexibility in responding to varying lighting situations without the need to interchange the filter.

1. The Laser
A well-proven technique for presbyopia is the « Presbyond Laser Blended Vision » treatment of the company Zeiss and developed by Professor Dan Reinstein in London.
This method applies mainly to all wearers of eyeglasses who have become presbyopic: hypermyopic, myopic, astigmatic. It can also work for persons not wearing glasses and who have good distant vision in both eyes (in this case the situation is more delicate and tests conducted in the Clinic can enable us to determine if the operation is feasible).
The « Presbyond Laser Blended Vision » treatment consists in privileging one eye for distant vision and the other for near vision. The specific nature of this treatment is that it allows good intermediary vision for e.g. the computer screen that is normally placed at a distance of 50-60 cm. You can consult a document edited by Zeiss and available in English.
Before proposing such a treatment, tests are carried out in our Clinic to ensure that you can accept your new eyesight (80% of patients « pass » the test and can be operated). In general, this treatment is well tolerated since our visual system is highly adjustable and adapts easily to new visual conditions.
However, if you do not tolerate your correction for presbyopia, it is possible to reverse the condition and correct both eyes solely for distant vision. This is one of the advantages of the « Laser Blended Vision » treatment.
If you suffer from cataract, the operation consists in removing your crystalline lens, which has turned opaque and replacing it with an artificial crystalline lens. The « classic » implant allows you to see distant objects without your glasses, but you would need them for close vision. For patients wishing to do away with their glasses, there are « bifocal » implants which allow patients to see near and distant objects without glasses.
It is also possible to operate using the bifocal implant technique for patients who do not have cataract. In this case, French social security does not cover the operation and the entire cost has to be borne by the patient.

Myths About LED Lighting
Myth number 1: LEDs last forever
Like all light sources, LED sources slowly fade over time. This light output degradation, or lumen depreciation, is determined by testing LED sources over a period of 6,000 hours or more. Factors that can cause lumen depreciation include drive current and heat generated within the device itself.
Lumen maintenance describes how long a lighting fixture retains a certain percentage of its initial light output. White light sources used for general illumination are commonly considered to be at the end of their useful life when their light output falls below 70% of initial output. For white and coloured accent and non-task lighting, the lumen maintenance threshold is often considered to be 50%.
Well-designed LED lighting fixtures can retain 70% of their initial output for 50,000 hours or more, depending on operating conditions and other factors. At 24 hours per day of continuous use, such fixtures can deliver useful light for six years or longer — many times as long as incandescent sources, and up to twice as long as long-life fluorescent sources.
Myth number 2: LEDs are not bright enough
If you compare the raw lumen output of conventional lamps with the lumen output of many LED lighting fixtures, it often seems that LED fixtures deliver less light than the conventional alternatives. Such comparisons, however, are inaccurate and misleading, as they fail to account for the significant amount of wasted light in conventional lighting solutions.
Simply put, lumen output is a poor measure of the suitability of a lighting fixture for a given task. A better measure is delivered light — how much light a fixture delivers to a surface or area, as measured in lux (lx) or footcandles (fc). You can make accurate comparisons between conventional and LED lighting fixtures on the basis of delivered light, as it measures how much of a light source’s raw lumen output reaches a surface or area you want to illuminate.
To determine how much of a conventional lamp’s raw lumen output reaches a task area, you must discount any light lost in the fixture housing (often over 30%), as well as any light lost as a result of lensing, shading, and filtering. Since incandescent and fluorescent lamps emit light in all directions, you must further discount any light emitted in a direction away from the target area.
LED lighting fixtures are integrated systems in which the light sources (LEDs), the fixture housing, and the primary optics are inseparable. Lumen measurements of LED lighting fixtures, therefore, are performed on the entire system, and already account for light lost to the fixture housing and lensing. Furthermore, since LEDs are inherently directional, they emit almost all of their light output in the desired direction, rather than dispersing it in all directions. And since LEDs natively produce intensely saturated coloured light, they require no gels or filters which can block a significant percentage of a fixture’s light output (over 90% for certain shades of deep blue).
When comparing lighting fixtures on the basis of delivered light, LED fixtures often perform as well, and in some cases significantly better, than conventional fixtures, while consuming far less energy.
Myth number 3: White-light LED sources produce over 160 lumens per watt
Many manufacturers test their LED chips on lab benches at room temperature with short pulses that produce a high efficacy that cannot be achieved in practical use. While these results are not incorrect, they do not reflect the typical expected output of LED sources integrated into lighting fixtures. Although percentages vary, it is not uncommon to see efficacy losses of up to 40%.
Reputable LED fixture manufacturers do not base lumen measurements on the test results of their LED source suppliers. Instead, they use independent, third-party testing labs to measure and validate the output of their lighting fixtures according to test conditions spelled out in the LM-79 standard, published in 2008 by the Illuminating Engineering Society of North America (IES).
Some highly efficient white-light LED lighting fixtures can achieve efficacy of over 40 lumens per watt (lm / W), sufficient to earn ENERGY STAR and other energy-efficiency ratings. For example, linear LED cove lights from a leading manufacturer achieve efficacies of 43.9 to 53.1 lm / W in normal operating conditions.
Myth number 4: Three-watt LEDs are brighter than one-watt LEDs
Because of incandescent light bulbs, you’re probably used to looking at wattage to determine the light output of a light source: a 100-watt lamp puts out more light than a 60-watt lamp.
The fact is that incandescent lamps have a very low efficacy compared with CFLs, high-output fluorescent lamps, and LED light sources. All general service incandescent lamps use the same filament material heated to the same temperature, the only way to increase their light output is to increase the wattage. This is one of the main reasons why incandescent lamps are so energy wasteful.
LED sources are much more efficient at converting watts to lumens. Different materials can be used within the LED sources themselves, each of which has its own light extraction efficacy. For these and other reasons, two different LED sources can consume the same number of watts but differ widely in lumen output.
Because watts can’t be used as an index of light output, evaluating the “brightness” of LED sources for a given situation requires you to think differently about lighting. A standard 60-watt incandescent lamp emits a total of about 800 lumens, but the light is emitted equally in all directions. When you’re reading at your office desk, your book does not receive all 800 lumens from your desktop lamp, nor do you need it to. As described in Myth #2, the crucial measurement is delivered light. According to the IES, serious reading requires an average of 50 fc or 500 lx on the page. Many linear LED under-cabinet fixtures and other task lights can deliver this level of light while consuming far less than 60 watts. For example, an under-cabinet LED light from a leading supplier delivers 50 fc in typical desktop situations while consuming only about 6 watts per foot.
Myth number 5: LEDs generate no heat
Because they produce no infrared energy, the beam of light from an LED source is cool. However, waste heat is produced within the LED itself during the conversion of electricity into light. This waste heat must be properly removed from the lighting system to maximize fixture performance and to avoid damage to the LEDs. In well-designed LED lighting fixtures, heat removal is accomplished through carefully designed and engineered heat sinks that draw heat away from the LEDs and dissipate it into the air surrounding the fixture housing.
Myth number 6: LED systems cost too much
Initial fixture costs may be higher for some LED lighting solutions than for comparable incandescent and fluorescent lighting solutions. But initial fixture cost does not account for the total cost of owning, operating, and maintaining a lighting system. Because of their long useful life, LED lighting fixtures avoid the maintenance and materials costs which multiple relampings of incandescent fixtures require over tens of thousands of hours of operation. And because LEDs consume far less energy, annual power costs can be reduced by up to 80%.. The total cost of LED lighting systems, therefore, can be significantly lower than conventional systems. In fact, payback on LED lighting solutions can often be realized in less than three years.
Myth number 7: LED light quality is poor
Two important measurements of white light quality are correlated colour temperature (CCT) and colour rendering index (CRI).
CCT describes whether white light appears warm (reddish), neutral, or cool (bluish). The standard definitions of CCT allow a range of variation in colour that can be readily discerned by viewers even when the CCT value is the same. Ensuring colour consistency, therefore, is a major concern of LED manufacturers. Leading LED lighting manufacturers use various LED selection schemes (binning) to ensure colour consistency from fixture to fixture.
On a scale of 0 (worst) to 100 (best), CRI measures the ability of a light source to reproduce the colours of objects faithfully in reference to an ideal light source — the sun, for example, or an incandescent lamp. Most office, retail, educational, medical, and residential spaces require a minimum CRI of 70 – 90. Many white-light LED lighting fixtures available today achieve CRIs of 80 or better, comparable to many CFL lamps, quartz metal halide lamps, and some cool white fluorescent fixtures sufficient for the vast majority of applications.
Because of well-known shortcomings of the standard CRI test for LED lighting, some LED lighting fixtures with low CRI scores produce visually pleasing light that renders colours appropriately. Colour Quality Scale (CQS), a colour-rendering standard that better accounts for the unique properties of LED light sources, is currently under development. Until CQS or a similar alternative is in place, you should observe LED sources with low CRI scores in person to evaluate how well they render colour.

The optic nerve carries information from the eye to the brain, and is located in the back of the eye. Glaucoma is the name given to a group of eye diseases that damage the optic nerve. It is characterized by progressive damage to the optic nerve of the eye, the most common cause being increased pressure in the eye. In fact glaucoma is the leading cause of irreversible blindness worldwide. At first, patients lose side (peripheral) vision. But if the disease is not treated, vision loss may worsen, leading to total blindness over time.
The most common forms of Glaucoma are:
1. Open angle glaucoma
2. Angle closure glaucoma
The treatment depends on accurate and early detection and success depends on severity of the disease at presentation. Glaucoma patients don’t experience any symptoms and are unaware of vision loss until severe damage has occurred. On rare occasions, acute rise in eye pressure occurs and needs immediate medical attention. Glaucoma can be treated as well as controlled but cannot be completely cured. However if left untreated, it can lead to permanent blindness. Most forms of this illness are progressive and need long term care. At Geetha eye hospital, we provide the latest tools for the diagnosis of glaucoma. We are equipped with the latest lasers and machinery used for the surgical management of glaucoma.

Geetha eye hospital offers comprehensive services for diagnosing and treating various retinal disorders. Our retinal specialist makes use of the latest equipment to detect retinal conditions such as Di2betic retinopathy and Age related macular degeneration amongst others. At Geetha eye hospital, we realize that ophthalmology is increasingly becoming an equipment-based practice. Good results not only depend on excellent surgical skills but also on the capabilities of the instruments and machines used, which is why we continue to invest in the latest that technology has to offer.
a) Diagnostic procedure
1. Fundus Photography – Allows doctors to procure color photographs of the back of the eye.
2. Fluorescein Angiography (FFA) – This is a diagnostic procedure that photographs blood circulation of the retina. The process involves injection of a dye called Fluorescein into a vein in the arm or hand.
3. Visual Field Analysis – This procedure allows measurement of the full extent of the area visible to an eye that is fixating straight ahead.
b) Surgical procedures

01. What is the relationship between light transmission and shade cloth?
To answer this question it is easiest if we go back to basics with the fundamentals of light.
Light is part of the electromagnetic spectrum and this is measured in wavelengths using a nanometre (nm) or 1 billionth of a metre. The general rule is the shorter the wavelength the more energy.
Humans can see visible light which is between 400 nm and ~730 nm. We cannot see UV (ultraviolet) light which is between 290 nm and 400 nm.
The solar transmission through shade cloth is significantly reduced across all wavelengths and is dependent on colour. All colours reduce UV transmission, which is the cause of sunburn and skin cancer, by at least 90% and up to 95%. This is measured by UVR block. Heat or infrared is also significantly reduced, particularly by the dark colours which reduce the heat transmission by up to 90%. Shade cloth provides excellent protection against the harsh effects of the sun.
02. What is a UV block and how is it determined?
Polyfab shade cloth has been designed to block out UV (ultraviolet) light to varying degrees depending on the range.
To determine the UV block out amount, a test is required by the Australian Standard AS4174 – Synthetic Shade Cloth. This test measures the amount of UV light (290 nm – 400 nm) that is blocked by the shade cloth. This is either via reflection or absorption.
UV block is the inverse of UV transmission e.g. 95% UV block = 5% UV transmission.
03. What is cover factor?
To determine the cover factor of a shade cloth a test is required by the Australian Standard AS4174 – Synthetic Shade Cloth.
This test determines the percentage area of the fabric covered by the yarns and fibre of the cloth. It is affected by the density of the yarn, profile and type of weave. Please Note: it is not affected by the weight of the fabric.
04. What is shade factor?
To determine the shade factor of a shade cloth a test is required by the Australian Standard AS4174 – Synthetic Shade Cloth.
This test defines the amount of visible and invisible incident light that is blocked by a shade cloth.
Shade factor is the inverse of average transmission e.g. 70% average transmission = 30% shade factor.


It was one something that belongs only to science fiction, but now Japanese researchers have created invisible technology that’s the first step towards making objects invisible. The invisible technology comes from 2003 but its developers say that the Harry Potter like invisibility cloak is just the beginning.
The team led by doctor Susumu tachi from Keio University is now adapting its findings to help pilots, drivers, doctors and others. Retro reflective projection technology uses a computer, a video camera and projector to shine background images onto the front to the subject wearing specialized clothing creating the illusion invisibility.
What makes the invisible technology unique is a fabric made of glass beads only 50 microns wide, which can reflect light directly back at the source much like a movie screen. Viewed from near the light source the projection is bright even in broad daylight and researchers say the material can be applied to almost anything. In the short term the team sees usage in car interiors, airplanes and helicopters they say blind spots could be eliminated and accidents and hard landings avoided by making walls seemingly transparent. The eventual goal though is to create an augmented reality that allows anyone to easily see information on real-world objects.
Looking to the future instead of glasses people could wear this, and it would act as a navigation system you could also tell you who someone is if you meet them around town. In the few years since the technologies invention the price if the material as well as that of computing has come down opening the door for smaller yet more powerful applications. With the use to increase safety or to create a completely new form of computer human interaction, the world is likely to see or possibly not see more of this camouflage technology in the future.


IntraLase™ FS Laser
The Eye Clinic of Racine offers Wisconsin’s most advanced technology
The IntraLase™ FS Laser brings a new level of safety and assurance to vision correction surgery in Racine and Kenosha by providing an all-laser approach for optimal precision. Now, the accuracy of a computer-controlled laser may be used to create the corneal flap for LASIK, providing unprecedented control and the ability to customize the flap for each of our patients.
Traditionally, the creation of a corneal flap was performed with a mechanical, hand-held device (known as a microkeratome) which moved across the cornea to cut the flap.
The IntraLase FS laser is a safe, computer-controlled alternative to a mechanical microkeratome for creating corneal flaps in the LASIK procedure. Using the IntraLase FS Laser takes LASIK safety to the next level by significantly reducing the chance of rare complications.
To make the corneal flap, the laser beam is focused into a tiny spot of energy that passes harmlessly through the outer layers of the cornea until reaching its exact focal point within the central layer of the cornea. There the corneal flap procedure is initiated, silently and painlessly, with remarkable precision.
Why The Eye Clinic of Racine uses the IntraLase™ FS Laser:
- IntraLASIK provides our patients with an extra margin of safety.
- IntraLASIK allows us to perform LASIK on patients with thin corneas because we can make a precise, more shallow flap, which allows us to correct higher levels of refractive error.
- IntraLASIK makes laser vision correction an all laser procedure, which significantly adds to its precision and predictability.
- IntraLASIK also creates better fitting flaps. Once put back in place, these flaps form a tight seal, making flap dislocation after the procedure more difficult.

In the science of image processing, two-dimensional (2D) object becomes raw material that
can be processed into another form to get the desired information. Within its development, the image processing refers to three-dimensional (3D) images which have more angles than the 2D object, so that we could get more information from the object.
Various methods for reconstructing 3D objects have been done by various researchers. Reconstructing 3D objects from multiple images is done by combining some calibrated 2D images (Kolev, Brox, & Cremers, 2012). The use of the Voxel Hashing algorithm is to reconstruct 3D objects to achieve good quality results with scale (Matthias Nießner, 2013). The use of Voxel Hashing improves the effective 3D point-based method used to reconstruct thin objects (Ummenhofer & Brox, 2013).
Reconstructing 3D objects in real time becomes an option when being implemented into game-based models and survival activities that require 3D viewable objects. The use of depth vision cameras like Kinect Fusion for taking human objects in 3D has a limited area (R. Newcombe, 2011). The development of kinect camera in its utilization is within the field of
In the event of surveillance undertaken, underwater observations become different things because the objects in the sea have uniqueness in every inch of them. Therefore an observation in the sea is needed by showing the whole object in 3D. Problems arise because during the formation of objects into 3D form there are differences in terms of lighting conditions, the determination of the edge of the object, the distance between the object and camera surveillance, as well as the existence of irregular noise around the object to be reconstructed.
This research is conducted to determine the application of which method that is suitable for taking underwater objects and reconstructing objects in 3D. Reconstruction will be done by taking multiple images in 2D form, shooting will be done by ROV (Remote Operated Vehicle), and ROV will be equipped with sensors and actuators that set the accuracy of each distance.
In the reconstruction of 3D objects, several studies have been done. Initial methods such as
the use of laser light mixed with the use of the camera with relative position and scene measurement projected to an object to obtain the shape of objects to be reconstructed into 3D images (Dipanda, 2005). The use of low-resolution cameras to reconstruct a surface image of an object was performed without the use of a laser beam. The method was done by detecting the grid segment, then reconstructing the surface image of an object (Dvorak, 2010). On the other hand Kinect cameras manufactured by Microsoft have been developed. By using Kinect
Fusion, then the kinect camera would be able to quickly reconstruct objects captured in 3D, with the provision of objects being indoors (Izad, 2010).
Research 3D reconstructions
Various approaches used to maximize reconstruction are limited by the camera’s ability to capture images. The determination of point-based on reconstructing 3D objects into a fairly large selection, point-based can also be used to reconstruct thin objects (Ummenhofer & Brox, 2013), merging of multiple images to be reconstructed into 3D objects using Direct Linear Triangulation (DLT ) that allows reconstruction from simple cameras (Rachmawati,
2013). Differential scaling on multiple images is a problem for the DLT algorithm. Another way is to compress the scale using spatial hashing scheme or Voxel Hashing (Nießner, 2013). To create faster and real-time reconstruction, images are taken from the video by dividing the image into segments, then checking the image connectivity of each segment using the connectivity constraint coupled with spatio-temporal multi-view reconstruction which is useful to reconstruct 3D objects in real time (Oswald, 2014). The retrieval of objects by Martin and Oswald creates a more detailed picture of previous engineering techniques, but the focus on the object will be much disturbed by the ever-changing noise due to real time shots. Backgrounds such as floors, walls, and other objects will give a large noise to the object. Signed Distance Fields (SDFs) technique will separate the object from the floor as well as the surface of the wall, so that the objects will be easier to reconstruct (Dzitsiuk,
2017). Techniques used to obtain objects are by reducing effective noise in the room because the surface of the wall and the surface of the floor have the same segmentation. However, if the surface is dynamic and has a different structure such as the seabed or even rocks, the object reconstruction will be more difficult to do because the object will be biased with other objects.
Research 3D reconstructions
3D reconstruction is also a research area that is being developed in the world of robotics. 3D simultaneous localization and mapping (SLAM) technique is very actively used because the robot poses determination and geometry planning needs fast and accurate estimates. 3D reconstruction is a requirement because of the task of robotics in localization, navigation, and exploration (Bylow, 2013). In addition to use in the world of robotics, 3D reconstruction is also used for survival purposes.
Research 3D reconstructions
The research conducted by Xu Yongzhe in 2015 using multi-camera to reconstruct the ground surface into 3D coordinates. The system will detect floors, walls, or buildings. This can improve the tracking system of moving objects. This technique uses 3D reconstruction SFM (structure from motion) which reconstructs 3D geometric from a set of 2D images captured in real time (Xu Yongzhe, 2015).

Weapons are useful by themselves, but there is some additional gear that weapon users attach to their weapons so that they can facilitate efficient operations in the activity that they are undertaking. The most significant aim of these firearm optics is to enhance the visibility of the person using the weapon to land the desired target. There are others to consider in different classifications like binoculars, monocular or spotting glasses. Nonetheless, weapon mounted optics add to your fervour and shot precision. When looking for gun optics, you should first comprehend the principle motivation behind utilising your weapon and the movement you wish to take part in. For instance, if you are not aiming at far away targets then you will not need optics that concentrate on far away items. Some undertakings require a laser. The laser itself is undetectable to the bare eye, yet shows up on the objective clearly.
If you are a sniper who enjoys shooting things from long ranges, then you would prefer purchasing something that can achieve high zooming capabilities and still present a clear image. Such apparatus can even present you a target clearly which is roughly a thousand yards away. As long as you know how to work the optic that you are using, you are in the ideal position of playing out all that you want. There are different types of weapon optics depending on the activity that you are going to undertake. From a standard optical scope to a laser scope to range locater blend, decisions should be made. Ask yourself the necessary questions to discover the type of optics that you require in your activity. Laser optics for hunting are more up to date on the market and are easily available. Most of them possess LED reticle that is conveyed on a viewfinder. The reticle can be changed to any of a few sorts relying upon the model you are taking a gander at.
For longer range hunting, laser optics take a jump to holographic optics. They use a laser column to wander out a crosshair towards the objective you are occupied with. Once located, this kind of optics for hunting is a standout amongst the most exact accessible. They are ideal for somebody intrigued by shooting in scopes of around one hundred and fifty yards, however, don’t offer the client some amplification. Weapon optics are extra contraptions that are appended to the weapon for expanded usefulness. They improve operations in various capacities. You can even attain an accuracy of up to a thousand yards highly dependent on the weapon that you are utilising.


Microelectronics and Genetics to Study Retinal Neuronal Circuit Dynamics
The mammalian retina represent a unique opportunity to study the dynamic computations performed by the brain and it has a 2D layered structure that is ideal to be analyzed by MEA technology. The mammalian retina contains complex circuits extracting specific features from visual input (decrease or increase in light intensity, color, moving objects).
Microelectrode arrays integrated with dedicated electronics provide the possibility to access dynamics of cell populations by simultaneously measuring activity of many cells in a network. In particular, complementary metal oxide semiconductor (CMOS) based MEAs feature high spatio-temporal resolution and high signal-to-noise ratio.
The main goal of the project is to develop a new strategy to record light pattern evoked activity from genetically identified retinal circuits in a high-throughput manner.

WHAT THE RESEARCH IS:
An alternative to copper conductor for submarine cables — and the first major development in cable technology since the early 1990s. Facebook researchers have partnered with Alcatel Submarine Networks to develop the first aluminum conductor for submarine cable systems.
HOW IT WORKS:
In the past 10 years, fiber-optic cable capacity has grown from 5 gigabits per fiber pair (FP) to more than 20 terabits per FP. We are rapidly approaching the per FP Shannon limit (the theoretical maximum capacity that can be transported by an optical fiber). Work has been done to increase the bandwidth per optical core — the task now is to increase the total number of optical cores. In other words, we need a way to increase the number of FPs per cable.
As a conductor, aluminum allows for a much lower cable voltage drop, which allows for a higher number of FPs per cable. That makes aluminum a solid option to increase the number of FPs per cable — that’s also significantly less expensive than copper.
WHY IT MATTERS:
These systems with a large number of optical fibers are an important first step toward space-division multiplexing systems, which could help increase the capacity of cables in the future.


NaviDate is developing a Passive Optoelectronic Tracking System (POTS) for the monitoring of moving objects based on passive optoelectronic devices and the subsequent software processing of the footage.
The system provides Detection, Recognition, Identification, Localization, and prediction of movements of the monitored objects in real time. The basic principle of our solution is stereovision with multiple cameras and evaluation of image processing in real time. Deep Learning is used for the object recognition and identification.
The cameras work within the range of visible spectrum, while thermal cameras are used in case of worsened weather conditions (such as reduced visibility, darkness, or adverse weather). The core of the system is its software package, which ensures the processing of the captured footage and its analysis. The system continuously monitors the space and provides identification of moving objects. It gives the operator graphic information about the location of the monitored object as well as its distance. The operator can display the route of the monitored object or trace its movement on a given trajectory in a specific time sequence. Should they wish to display the actual view of the monitored object, they can turn on the object tracking view. After selecting an object, the system will display it in the view on the left. Using artificial intelligence and machine learning, the system is able to learn to recognize different categories of objects (such as drones, planes, people, cars, etc.) as well as identify objects which are already familiar (such as a service truck, a plane of a known airline company, a service technician, etc.).


Essay on Replacing Incandecent Light Bulbs with LED Lighting. The law mandated strict new energy standards for lighting designed to kick-start a new era of greener, longer-lasting,more cost-efficient light bulbs and this meant kicking outdated, inefficient bulbs to the curb”(Crist).
LED lighting has both advantages and disadvantages. Check out the pros and cons of LED lights in this debate and essay article.White light in LED can be produced in two ways. One method is, using three individual LEDs which producing the primary colours and then mixing them to produce the white light. Another method is, using the principle which is using in fluorescent lights, a phosphor material is used to convert light from UV or blue LED to white light.It mentions that these lights are radically reducing the consumption of electricity and they are more cost-efficient than incandescent lamp. According to the author, one way of maximizing the potential of these lights in lighting design is by applying the principle of refraction in a screen format to distribute the light from LED.
LED light bulbs emit light through the use of a semiconductor that releases light energy when an electrical current is passed through it. This way of producing light differs from CFL light bulbs, which pass energy through mercury vapor to generate UV light, which is then enthralled by a phosphor covering inside the lamp, causing it to glow.
LED (Light Emitting Diode) A light-emitting diode (LED) is a semiconductor light source.(7) LEDs are used as indicator lamps in many devices and are increasingly used for general lighting. Appearing as practical electronic components in 1962,(8) early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very.
A light-emitting diode (LED) is a semiconductor device that produces light from electricity. LEDs last a long time and do not break easily (compared to incandescent lightbulbs).They can produce many different colors. They are efficient - most of the energy turns into light, not heat.
Advantages Of The Electric Light Bulb. Introduction The electric light bulb has basically remained unchanged for over a hundred years. The new federal energy-efficiency standards have taken effect and are pushing out the old uneconomical light bulbs for more efficient options, such as light emitting diodes.
A led lamp is a solid state lamp that uses ledes ( Light-Emitting Diode ) as a light source. Because the light capable of emitting a led is not very intense, in order to reach the luminous intensity similar to other existing lamps such as incandescent or compact fluorescents LED lamps are composed of clusters of LEDs, in greater or lesser number, according to The desired luminous intensity.
Information About Light Bulbs for Kids. Outdoor solar light bulbs contain solar cells that convert sunlight into electricity as a power source for the light. In LED bulbs, an electric current activates a microchip that powers up multiple tiny light-emitting diodes to produce light.
Advantages of LED Lights The operational life of current white LED lamps is 100,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. The long operational life of an led lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours.
How Do LED Lights Work? It’s really simple actually, and very cheap to produce, which is why there was so much excitement when LED lights were first invented!. The Technical Details: LED lights are composed of two types of semiconducting material (a p-type and an n-type). Both the p-type and n-type materials, also called extringent materials, have been doped (dipped into a substance called a.
The International Year of Light 2015 was an extraordinary opportunity to talk about how important light is in our everyday lives. From its technological and manufacturing impacts to applications in healthcare, from its use in astronomy to molecular biology, and from poor lighting to light pollution, light is much more than just the switch of a bulb.

Patch cord is also known as optical fiber connector, refers to the cable on both ends mount connector plug, used to implement the light patch activity connection. At one end with a plug is called the tail fiber. Fiber optic jumper (Optical Fiber Patch Cord/Cable) and coaxial Cable are similar, but no mesh shielding layer. The center is the spread of light glass core. In multimode optical fiber core diameter is 50 microns to 65 microns, roughly the comparative with the thickness of a human hair. And the diameter of the singlemode fiber core is 8 microns to 10 microns. Core surrounded by a layer of refractive index is lower than the core glass envelope, to make the optical fiber to keep within the core. Outside is a thin layer of a plastic coat again, to protect the sleeve.

LED lighting is available in different shades of white. Offering more efficient or more pleasant lighting, warmer or cooler, whiter or yellower, depending on the need. The choice of shade of white of a LED light is generally a very subjective thing.
In Northern European countries for example, the tendency is to opt for warmer (yellower) shades. While in Mediterranean countries, the trend is focused more on cooler (whiter) lights. But this is only a trend, an observation, and certainly not a rule…
WHITE vs WHITE: MAKE A DIFFERENCE
The shade of light or the temperature of the colour is measured in degrees Kelvin (K).
The lower the colour temperature (2700K or less) the more yellow the LED will look and will be known as extra warm white. For 3000K, we talk about warm white (between yellow and white: less obvious yellow but not completely white).
The higher the colour temperature (4000K, 6000K, 6500K) the whiter the look of the LED (4000K) even blue white or daylight (6000K). The white of this type of lighting (6000K or more) is referred to as cool or very cool (daylight)
Whiter than white – sometimes too white
A second important parameter is what we call the CRI (or Color Rendering Index).
This index, in addition to the colour chosen, qualifies the degree of purity of LED light obtained. It is measured on a scale from 0-100. Good quality LED lights for displays or interiors generally have a CRI of approximately 85. You could juggle between a 2700K super warm white light or 3000K warm white with a CRI of 80 or 95.
For example: A LED light of 4000K with a CRI of 95 means: white light for which the colour rendering has an accuracy equivalent to 95%. (ideal for a jeweller)
By comparison, an orange sodium light on the motorway will have a CRI of 20-29. Consequently, colours can be distorted and then impossible to recognise. By using a LED light, or a device which uses special diodes of even higher quality and a CRI in the range of 90-95, it may mean that the price is higher.
How to find your way around LED light shades?
To make it easier to understand, you can also compare the diodes used in LED units to diamonds in jewellery: it is possible to find a diamond and diamond rings of different purities.
You pay more or less depending on the quality and the price that you are prepared to invest. LED lighting is comparable. We can propose various types of bespoke diodes and a unit fitted with the perfect shade may be proposed.
A member of our team would be delighted, where appropriate, to visit your premises if you have any questions about your project. He/she would be able to present the LED light units and show you the shades and differences between one type of unit and another, as well as food lights.

Do You Want Some HID Lights (Xenon Brenner)?
Due to the introduction of high-intensity discharge lamps or high-intensity discharge lamps for the first time in the BMW 7 series, more and more cars are installed every year. Soon, they will become the standard in the automotive industry. The reason is that the amount of light generated by power consumption is greatly improved compared to standard halogen lamps compared to HID lamps. This reduces the size of the headlamps and provides better illumination than previous models.
In operation, HID lamps burn metal salts, providing 2,800 to 3,500 lumens, while halogen headlights provide 700 to 2100 lumens. The benefits of having a HID lamp are obvious. However, manufacturers are slow to address some of the issues related to the implementation of new technologies. For example, HID lamps require a higher voltage than normal bulbs to function properly, sometimes as high as 85 volts.
In addition, they may take a few minutes to warm up and begin to produce full output. This can be solved by using helium instead of argon. In this way, they can produce a minimum of enough light when turned on. This is why the car light is called a xenon lamp or xenon brenner.
The most important issue with these lights is illuminating. They produce a 40% increase in reflectivity compared to conventional bulbs. This huge light is a danger to all drivers from the other direction. In addition, the accumulation of dirt on the lens increases glare.
Therefore, according to ECE 48, the lighting system requires an automatic beam leveling and lens cleaning system to prevent glare from damaging other drivers on the road. Another problem with these lamps is there mercury content in the old bulb. The new type produced since 2004 is mercury-free but incompatible with older systems.
In general, incompatibility is a major problem with these lamps, which is why they are widely used. It is almost impossible to install a HID bulb in a filament bulb headlamp. In fact, it is illegal in almost every country because it causes intense illumination and HID bulb failure.
In addition to the competition, you can choose from a wide range of choices depending on the color and temperature of the high-intensity discharge lamp. From 5000 K to 12000 K, you can choose as needed. If you have seen the strong reflection of a luxury headlight, you will usually pass the other side or rear view of the road. The blue-and-white tone of the suffocating light caught people’s attention. Not long ago, high-intensity discharge (HID) headlamps were designed for high-priced cars. Don’t worry if your car is not equipped with HID. You only need to be connected to the internet, and there are many online stores that offer HID lights for your Honda. The Honda HID kit includes all the accessories needed for the conversion.
There are kits on the market that offer a complete headlamp with an HID bulb, but the old models do not have an automatic beam leveling and cleaning control system. Lenses, which are useless for most people. Finally, the cost of these lamps is significantly higher than that of halogen lamps. However, this is offset by low fuel consumption and lamp life.
All of these issues will definitely slow down lighting to become the dominant type of the automotive industry, but this will not stop it. The benefits of this system are too important to be lost. Most of the problems will be solved in the next few years, and as most new cars are equipped with HID headlights, we will see more and more on the road. Find more about xenon brenner.


Video projectors have long been utilized in business and commercial entertainment and certain high-end home theatre systems as a presenting tool. However, video projectors are becoming more widely available and cheap to the general public. Before you buy your first video projector, consider some of these helpful hints.
Video Projector Types
There are two types of video projectors: DLP (Digital Light Processing) and LCD (Liquid Crystal Display).
- DLP projectors make use of a light source, a colour wheel, and a chip containing small tilting mirrors. The light is projected onto a screen after passing through the colour wheel and reflecting off the mirrors.
- LCD projectors use a light source that sends light through three LCD chips (assigned to the primary colours red, green, and blue) to make and display images.
Lamps, LEDs, and Lasers
Consider whether the projector’s light source is a lamp, LED, or laser. Depending on the type of light used, each of the three possibilities has advantages and downsides.
Brightness and light output
The ANSI Lumens rating is the most accurate way to determine whether a projector generates a bright and clean image. Even in a dark setting, the image will appear muddy and soft if the light output is too low.
Video projectors with 1,000 ANSI Lumens or more are bright enough for home theatre use. The demand for more or fewer lumens is also affected by room size, screen size/distance, and ambient room light connections. Although the light output capabilities of video projectors have improved, they still perform best in a darker room.
Complements brightness and Contrast is the ratio between the black and white portions of an image. High contrast ratios deliver whiter whites and blacker blacks. A projector may have a great Lumens rating, but your image will look washed out if the contrast ratio is low. A contrast ratio of at least 1,500:1 is good in a darkened room, but 2,000:1 or higher is considered excellent.
Display Resolution and Pixel Density
If you watch HDTV most of the time, acquire the highest feasible real pixel count (preferably 1920×1080). For DVDs, a natural pixel count of 1024×768 is sufficient. The display of 720p HDTV transmissions requires a pixel count of 1280×720.
Don’t Forget to Include the Screen!
Screens are available in a variety of sizes, and costs. The projector determines the ideal screen type, the viewing angle, the quantity of ambient light in the room, and the distance between the projector and the screen.
A Home Theater System in Noida with a video projector as its focal point can significantly improve the home entertainment experience. However, do not reach for your wallet and purchase whatever is advertised or on sale.
Prices for video projectors range from several hundred to several thousand dollars, depending on the above considerations. Soundville.com can provide you with the best music equipment at a reasonable price.
The ease of installation and setup allows you to experiment with different screen sizes and distances. You can even place a sheet on an outside wall if your projector is portable (or garage door).


Projectors have become indispensable tools for many applications, from educational institutions and business presentations to home theatre setups. However, the upfront cost of projectors often raises eyebrows, leaving many wondering why these devices can be so expensive. In this blog article, we will delve into the factors that contribute to the high price tags of projectors and shed light on the reasons behind their seemingly lofty prices.
Advanced Technology and Components:
One of the primary reasons behind the high cost of projectors lies in the advanced technology and high-quality components used in their construction. Projectors rely on cutting-edge optics, precision lenses, and high-resolution imaging chips to deliver exceptional image quality. These components are often manufactured by specialized companies and are priced accordingly. Moreover, manufacturers invest heavily in research and development to improve projector features and performance, adding to the overall cost.
Resolution and Image Quality:
The resolution of a projector significantly impacts the final image quality it produces. Projectors with higher resolutions, such as 4K or even 8K, require more sophisticated and expensive imaging chips, resulting in a higher price point. As consumers demand higher image clarity and sharpness, manufacturers continue to invest in enhancing the resolution capabilities of their projectors, contributing to the expense.
Light Source Technology:
The type of light source used in projectors plays a pivotal role in determining their price. Traditional lamp-based projectors have been the norm for a long time, but they are gradually replaced by more advanced light sources, such as laser and LED technologies. While these newer light sources offer benefits like longer lifespan, lower maintenance costs, and improved colour accuracy, they also add to the upfront cost of the projector.
Lumens and Brightness:
Brightness, measured in lumens, is another critical aspect of projectors. Devices with higher brightness are better suited for large venues and well-lit rooms. Achieving higher brightness levels often requires more powerful light sources, which can drive up the cost. Additionally, high dynamic range (HDR) and wide colour gamuts enhance colour reproduction, increasing the price.
Portability and Form Factor:
Projectors come in various sizes and form factors, ranging from compact portable models to large, high-end installations. The design and engineering required to create sleek, portable projectors with excellent performance can raise manufacturing costs. Conversely, professional-grade projectors for commercial applications often require heavy-duty materials and precision engineering, impacting their price accordingly.
Brand reputation and market positioning also influence projector pricing. Established and reputable brands often charge a premium for their products, given their proven track record of delivering high-quality projectors. Consumers may be willing to pay a higher price for a brand they trust, contributing to the perception of expensive projectors.
In conclusion, the seemingly high cost of projectors can be attributed to a combination of factors, including advanced technology, high-quality components, resolution and image quality, light source technology, brightness capabilities, design and form factor, and brand reputation. As technology evolves, we can expect projectors’ costs to decrease gradually over time. Nonetheless, investing in a high-quality projector can offer an unparalleled audio-visual experience and be a worthwhile long-term investment for personal and professional use.

The design of Dianming's optical lens is able to focus the light which comes from wide angle (120 degree) of LEDs into narrow angle to be easily read by road users, meanwhile the luminous efficacy got improved and the electric current for LEDs is reduced. As a result, it extends the life span of the VMS as well as energy-saving.
Modular optical lens design means convenient for assembly, maintenance and waterproof. High quality material of optical lens contribute UV-resistance and high light transmittance. The design in honeycomb bead surface is helpful to reduce the glare from sunshine and street light.
The surface of Dianming's VMS applies the unique matte abrasive structure which will create a diffuse reflection to the sunlight; thus the brightnessreflection from front surface of the VMS is reduced.
The optical lens of Dianming's VMS applies the internal light absorption design which will decrease the external light reflection on the lens, so the brightness reflection of the VMS is ulteriorly reduced.
With the matte abrasive surface and the internal light absorption design on lens, the contrast ratio of Dianming's VMS can reach as high as 20:1 in white color, under the external illumination at 40000 lux.
Besides traditional VMS structures which use visor design on the surface to increase the contrast ratio, Dianming also produce European style VMS, which its surface with optical lens is more smooth, thus no dust or snow will stay on the VMS surface. The display content on the VMS will be clear and complete all the time.

Additionally, some special size fonts are also available without customization.(MULTI-LANGUAGES, various sizes fonts)


In the contingent socio-economic context, public and private companies are called upon to respect and enforce the containment measures of Covid-19, the global pandemic now widespread in all states of the world. One of the “key” tools for containing the virus is represented by thermal cameras, an infrared screening device that allows the detection of body temperature at distance.
The principle underlying the operation of thermal cameras is thermal radiation: the greater the intensity of the radiation detected, the higher the body temperature.
Are thermal cameras reliable tools?
Not all thermal cameras are the same: it is possible to find them on the market and on the main e-commerce platforms for little money, versions with questionable levels of precision. It is understandable that tools of this type do not have the adequate characteristics for all those professional activities that are in contact with tens of hundreds of people every day. Just think of shopping centers, stations, supermarkets, pharmacies, waiting rooms, counters, gyms, hospitals.
Activities such as those just mentioned are sometimes not equipped with a guard at the entrance and require professional infrared thermal cameras with access control systems and temperature detection of several people on the move.
The professional infrared screening solution designed by Omitech
Omitech thermal cameras represent a convenient and safe solution for offices, airports, stations, large waiting rooms, shopping centers, supermarkets and hospitals.
Omitech thermal cameras identification system uses intelligent technology to detect body temperature. Thanks to a double camera system, the device can boast a recognition capacity of 30 people per minute. The detection of the body temperature of several people comes in a very short time, an enormous advantage in contrasting slowdowns and queues near the entrances.
The temperature measurement response is fast (0.3 seconds) and facial recognition automatically measures the temperature when the person is within 0.5-1.2 meters. Double camera and facial recognition also allow the identification of the temperature of people even when they are wearing eyewear and masks.
The result of temperature measurement reaches an accuracy of +/- 0.3 degrees, so precise that it is classified and certified as a medical device.
Omitech infrared screening device is ready for use and does not require dedicated personnel to detect temperature.

We present a facile solution-based procedure for tailoring the surface properties of aluminum oxide nanoparticles (AlOx-NPs) by the formation of tunable core–shell systems with self-assembled monolayers. By employing chained molecules with a phosphonic acid anchor group and either hydrophobic or hydrophilic chains the surface properties of the nanoparticles change dramatically. So, the solubility can be tuned orthogonal from trifluorotoluene (CF3–C6H5) for hydrophobic shell to water (H2O) for hydrophilic functionalization respectively. Spray coated films of those functionalized nanoparticles exhibited superhydrophobic or superhydrophilic properties. The surface properties can be tuned smoothly by the formation of a mixed ligand monolayer from corresponding stoichiometric mixtures of the ligands. The core–shell nanoparticles were investigated by means of thermogravimetric analysis, TGA; Fourier transform infrared spectroscopy, FTIR; and static contact angle goniometry, SCA. The effect of different dipole moments of the SAM molecules in mixed shell nanoparticles to their stability in dispersions was studied by zeta potential measurements.

- B.S. in Physics will be completed in Spring 2018
My research involves static high pressure/temperature studies of various materials using laser heated and resistive heated diamond anvil cells (DAC). Through my work I have carried out experiments in the multi-megabar pressure regime using a DAC. I have used electrical discharge machining and laser drillers for gasket preparation, and single and triple grating spectrometers for Raman spectroscopy to measure pressure and collect data on samples. Tin nitride has shown the remarkable behavior of a band gap energy that increases as pressure is increased, and my work on tin nitride has involved setting up an optical absorption system to measure bang gap energies in the visible range of samples at high pressure.
Both CO2 and Nd:YAG lasers have been used to laser heat conducting materials and wide band gap semi-conductors. I have conducted X-ray diffraction and absorption at Argonne National Lab during these laser heating experiments to give insight to the structural and electronic behavior of Sn3N4. Through the X-ray absorption experiments I have become familiar with performing DAC experiments using beryllium as a gasket material. This highly toxic low-Z metal is necessary for absorption experiments so as not to scatter incident X-rays.

An LED monitor (short for Light Emitting Diode) or LED display is a flat screen, flat panel computer monitor or television. It has a very short depth and is light in terms of weight. The actual difference between this and a typical LCD monitor is the backlighting. The first LCD monitors used CCFLinstead of LEDs to illuminate the screen.
LED monitors offer many benefits when compared to those which are CCFL lit including:
- Typically are less expensive
- Broader dimming range
- Overall more reliable
- They run at a lower temperature, and consume much less power, as few as 20 watts
- Higher dynamic contrast ratio
- Longer lifespan and less environmental impact
