*Check Original Page: Why does wireless camera system send so many email or APP false alert?
To explain this question, we need know the theory how motion detection works.
The NVR system can detect small image optical change. It can be triggered by small image change from camera. Image is transmitted by light signal.
Therefore, even if there is no object in front of camera such as human, animal or car, system may still be triggered by small light change such as floating cloud, shaking leaf.
Most customers hope the system can only be triggered by big object like people and ignore small movement. But based on the theory how motion detection works, there are false alarm.
It is hard to say the system is faulty since not only ANRAN brand system faces such issue, but also other brands who use light sensor to work for motion detection function.
How to reduce email and APP false alert?
1. To reduce false alarm, you can turn the sensibility to lower and set the alarm area. (The alarm area defaults to all areas have been selected.)
2. Click “Arming Time”, you can set the notifications time of email alert and APP alert.
3. Please upgrade your camera (you can upgrade it from the network server)

Samsung Electronics has launched two new sensors as part of its ISOCELL Vizion lineup: the ISOCELL Vizion 63D and the ISOCELL Vizion 931. These sensors are designed to enhance visual capabilities in various applications, including robotics and extended reality (XR).
The ISOCELL Vizion 63D is a time-of-flight (ToF) sensor that measures distance and depth by calculating the time it takes for light to travel to and from an object. It is an indirect ToF sensor that measures the phase shift between emitted and reflected light to sense its surroundings in three dimensions. This sensor is ideal for service and industrial robots, XR devices, and facial authentication, where high-resolution and precise depth measuring are crucial. It is the industry’s first iToF sensor with an integrated depth-sensing hardware image signal processor (ISP), enabling a reduction in system power consumption. The sensor can process images at up to 60 frames per second in QVGA resolution and achieves high VGA resolution within a compact optical format. It also boasts enhanced light sensitivity and reduced noise for sharper image quality.
The ISOCELL Vizion 931 is a global shutter image sensor designed to capture rapid movements without distortion. Unlike rolling shutter sensors, which scan the scene line by line, global shutter sensors capture the entire scene at once, resulting in sharp, undistorted images of moving objects. This sensor is well-suited for motion-tracking in XR devices, gaming systems, robots, and drones. It is optimized for iris recognition, eye tracking, facial and gesture detection in head-mounted display devices. The ISOCELL Vizion 931 achieves high quantum efficiency and incorporates advanced technologies to maximize light absorption.
Both the ISOCELL Vizion 63D and ISOCELL Vizion 931 sensors offer design flexibility and are currently being sampled to OEMs worldwide. Samsung aims to drive innovation in the image sensor market with these advanced sensors.

Close-up lenses measure their power in diopters with the formula.
The technique of Stacking Lens typically involves using a telephoto lens on your camera as your normal lens, then taking a shorter focal length lens and using a filter to filter adapter, mount it to the telephoto in a reversed position. When you are doing this, you are essentially using the reversed lens as a supplementary close-up lens. So using the above formula reversing a 100mm lens would be a +10 Close-up; while a 50mm lens would be a +20 Close-up! You can easily see why 50mm and shorter lenses are a favorite for this technique.
To stack two lenses you need a filter to filter adapter. These are also sold as male to male adapters or as macro-coupling rings. If you can’t find an adapter with the filter size you need, you can mate it with a step-up or step-down ring, like the one pictured here. In this case it is a 58mm to 77mm adapter that is attached to a 77mm to 72mm step-down ring.
Magnification of Stacked Lenses
The above formula does not account for any extension that may already be built into the lens. You can also add your own extension to increase the magnification. You can also increase your magnification with a multiplier or tele-convertor. A multiplier will multiply your magnification.
A problem you can run into with stacked lenses is vignetting, or the darkening of the corners of the frame. This is why it is always a good idea to use a fast lens, like a 50mm f/1.8 as your reversed lens.

Researchers from the UJI (Universitat Jaume I) Optics Research Group (GROC) in Castelló, Spain, have developed a new tool for the field of scientific imaging. A sensor of just one pixel can record high-quality images and distribute them securely, that is, without allowing non-authorised people access to information.
In 2009, Willard S. Boyle and George E. Smith received the Nobel Prize in Physics for having succeeded in capturing images with a digital sensor. The key lay in their design of a procedure that recorded the electrical signals generated via the photoelectric effect in a large number of image points, known as pixels, in a short period of time. The CCD sensor in a photo camera acts as the human-eye retinal mosaic. Since their invention, the use of the digital format for recording images has revolutionised various fields, photography amongst them, as it facilitates image processing and distribution.
Nowadays, digital cameras with CCD sensors of 5, 6 and even 12 million pixels are common. As the dimension of sensors is always the same (typically, 24.7 square millimetres), one may logically think that the higher the number of pixels, the better the image quality will be. However, this idea is not quite right as there are other factors involved, such as the quality of the lens. Conversely, more memory is needed for storing these images (the size of a 6-million pixel digital camera image is about 2 Mb).
In recent years, the world of image technologies has become a booming scientific field, mainly because of biomedical applications. Holographic microscopes, light-operated scissors, laser scalpels, and so on, have enabled the design of minimally invasive diagnosis and surgery techniques. In this context, one amazing possibility that researchers have recently demonstrated is that of capturing high-quality digital images with a sensor using just a single pixel. This technique, baptised by scientists as ‘ghost imaging’, is based on the sequential recording of the light intensity transmitted or reflected by an object illuminated by a sequence of noisy light beams. This noisy light is what we observe, for example, when we illuminate a piece of paper using a laser pointer.
The GROC researchers have successfully captured 2D object images (such as the UJI logo or the face of one of the maids of honour from the famous Las Meninas painting as reinterpreted by Picasso in 1957) using this amazing single-pixel camera. The key for the success lies in the use of a small 1-inch LCD screen, similar to that used in video projectors or those we have at home, but in miniature. Its properties or features can be modified using a computer in order to generate the necessary light beams.
Furthermore, the researchers from Castelló have demonstrated, for the first time and on a worldwide scale, the possibility of adapting the technique in such a way that it allows an image to be securely sent to a set of authorised users using a public distribution channel, such as the Internet. The information transmitted is a simple numerical sequence that allows the image to be retrieved, but only if one knows the hidden codes enabling the generation of the noise patterns with which the pubic access information has been created.
The first results of this study, which is still under way, were published in the first July issue of the journal Optics Letters, and a month later Nature Photonics, the main journal in optics, included a review of it in its September issue, in the section containing the most relevant articles published in the field.
The technology applied to the single-pixel camera had not yet been used for image encryption, but it is being studied now by several research groups – including GROC– to obtain images of biological tissues which, because of their unusual transparency or their location in the more internal parts of the body (some centimetres under surface mucus), are difficult to view using pixelated devices such as those of today’s digital cameras. Furthermore, the researchers point out that using this technique for image encryption will improve safety in image transmission, product authentication, or will simply hide information from undesired people, thus making it a highly efficient tool against data phishing.
GROC is made up of around ten researchers under the coordination of Professor Jesús Lancis. It conducts its activity within the Department of Physics and the recently created Institute for New Image Technologies at the UJI. In addition to image technologies, the group is participating in a national project on ultrashort and ultra-intense laser pulses, which is financed by the Consolider Ingenio programme of the Spanish Ministry of Science and Innovation and the Seventh Framework Programme of the European Union. The project aims to establish this technology in Spain through the Pulsed Laser Centre in Salamanca (CLPU), a singular strategic infrastructure, which has the Spanish Government’s approval.

2 Details Individuals Do Not Really Comprehend Regarding To LASIK Eye ProceduresThe eye can be examined with relative ease as to both its function and its structure. A practical evaluation includes the capability to relocate the orbit and the response of the pupil to light and lodging.
The function of the eye might be evaluated in numerous methods. The patient might be asked to identify illuminated letter or items of varying sizes on exactly what is called the Snellen chart.
On the other hand, the examination of the structural part of the eye might be made in several ways. Stress within the eyeball is measured by a "tonometer." In certain illness, especially in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it needs to be well bore in mind that a patient with an eye issue might have other problems also. Typically other physical conditions are main and impact the eye as a consequence. The look of the eye can notify the client and the physician to problems in some disruptions of other parts of the body even before other signs provide themselves.
One's dependence on sight is highlighted when one deals with a temporary or possible long-term loss of this essential sense. Hence, when corrective measures are sought, certain types of vision correction such as contact lenses or glasses are recommended.
On the other hand, some people are bothered with that they have actually some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to motivate decreased utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Essentially, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgery is another form of vision correction. The only difference is that with this type of surgery, one's vision is remedied completely.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently transformed. This can be done utilizing an "excimer laser."
The primary purpose of this surgery is to develop a threadlike, rounded "flap" in the cornea using a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, enabling much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
Amidst the growing appeal of LASIK eye surgery, there are still disadvantages that individuals must understand. Probably, the primary reason why this kind of eye surgery has actually become well accepted is due to the fact that the majority of its cases had actually achieved success.
Nevertheless, in spite of its success, there are still some drawbacks. Here is the list:
1. It is an discover here operation applied to the most delicate part of the eye
Since LASIK eye surgery involves the operation of the retina, which is among the most sensitive parts of the eye, many individuals say that the operation can be very risky.
In other words, a simple error could nearly trigger an individual's lifetime blindness. Thus, it is very important to think about many elements prior to choosing whether LASIK eye surgery is the right restorative step one needs to go through.
2. It is not a perfect procedure
LASIK eye surgical treatment may remedy your vision however it does not necessarily mean that it can offer you a ideal vision. Even if statistical reports reveal that 70% of the clients may have 20/20 vision, this does not necessarily imply they have ideal vision also.
Offered all these things, it can be deduced that, over at this website in spite of the appeal of the operation, LASIK might not constantly be the perfect eye surgical treatment see this the way many people view it
Conversely, the examination of the structural part of the eye may be made in a number of methods. It should be well kept in mind that a patient with an eye problem might have other issues. Frequently other physical conditions are primary and affect the eye as a consequence. The appearance of the eye can notify the physician and the patient to troubles in some disruptions of other parts of the body even before other signs provide themselves.
Like its tangible counterpart, LASIK eye surgery is another form of vision correction.

Laser Area Scanners
Laser area scanners consist of a conical mirror and a rapidly rotating laser, which monitor a large area to detect movement or a presence within that area. Laser area scanners can perform many of the same functions as a light curtain, but the area that they monitor is much more flexible. Laser area scanners can be programmed to shape the area that they monitor to a very precise degree, allowing for monitoring of an area even if there is fixed hardware that would normally trigger their presence sensing. However despite the convenience of this programmability, the human potential for error in their programming means that laser area scanners are not considered as reliable as light curtains, and therefore are not suitable for SIL 3 environments.


Samsung was first reputed in June to chip away at a 3D facial acknowledgment innovation for its cutting-edge Galaxy leader telephone. It presently turns out that the talk has its formal premise as a patent application affirmed by the U.S. Patent and Trademark Office (USPTO) in late Q2 2018.

Also, the innovation may alternatively bolster vicinity detecting, night-vision camera, 3D time-of-flight sensor, eye position and look the following camera, and organized light for 3D detecting.
Samsung Patents Bio-Metric Camera Going to Compete with Apple’s Face ID
It was reputed that Samsung too was chipping away at a comparative component prone to make a big appearance in its cutting-edge Galaxy lead telephone in 2019. Presently, another report from Patently Apple, recommends that Samsung has been granted a patent for its 2014 documenting of a biometric camera by the U.S. Patent and Trademark Office (USPTO) in late Q2 2018.
As indicated by Patently Apple, the biometric camera incorporated into a cell phone will highlight iris acknowledgment that would be utilized to check a client’s iris through a handset’s forward looking camera. The patent report uncovers that the biometric camera framework incorporates a NIR (close infrared) light source on the cell phone while catching a picture to address encompassing light difficulties.
It likewise incorporates an expanded profundity of field (EDOF) focal point, a bandpass sift to channel through encompassing light, and an imaging sensor to change over a protest’s optical picture into an electronic flag for handling. Further, it likewise incorporates a processor intended to get video pictures of a client’s iris from the sensor that endeavors to coordinate it with beforehand enlisted pictures put away in an iris database, wherein if a match is discovered, the client is verified.
It also contains a drawn out profundity of teach (EDOF) focal point, a bandpass sift to channel through encompassing delicate, and an imaging sensor to change over a protest’s optical picture into a computerized sign for preparing. Further, it moreover includes a processor intended to acquire video photos of a customer’s iris from the sensor that makes an endeavor to coordinate it with in advance enlisted pictures spared in an iris database, whereby if a match is found, the purchaser is confirmed.
As per Patently Apple, the biometric camera incorporated in ideal with a cell machine will trademark iris acknowledgment that may be utilized to filter a customer’s iris by methods for a handset’s forward looking camera. The patent doc uncovers that the biometric camera framework includes a NIR (near infrared) delicate supply on the phone machine while catching a photo to deal with surrounding delicate difficulties.
Moreover, the biometric camera may alternatively do capacities together with closeness detecting, night-vision camera, 3D time-of-flight sensor, eye position and look the following camera, and organized light for 3D detecting.” Besides, cell handsets, the biometric know-in what capacity may likewise be utilized for TVs, journals or personal computer frameworks, in understanding to the patent.

Two Components Individuals Do Not Really Know About LASIK Eye Medical ProceduresThe eye can be analyzed with relative ease regarding both its function and its structure. A functional examination includes the ability to move in the orbit and the reaction of the pupil to light and accommodation.
The function of the eye may be tested in a number of ways. The patient may be asked to identify illuminated letter or things of varying sizes on exactly what is called the Snellen chart.
Alternatively, the assessment of the structural part of the eye might be made in numerous methods. Stress within the eyeball is measured by a "tonometer." In specific illness, especially in glaucoma, the tension in the eyeball is increased markedly.
Nevertheless, it should be well kept in mind that a client with an eye problem might have other issues as well. Often other physical conditions are primary and impact the eye as a repercussion. The look of the eye can inform the patient and the doctor to troubles in some disturbances of other parts of the body even before other signs present themselves.
One's dependence on sight is highlighted when one deals with a short-term or possible long-term loss of this vital sense. Hence, when restorative steps are sought, particular types of vision correction such as contact lenses or glasses are prescribed.
On the other hand, some people are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this reason, advanced surgical operations were developed to encourage reduced utilization of contact lenses or glasses. Among which is the now popular LASIK eye surgical treatment.
Basically, LASIK eye surgery is the short term for "Laser-Assisted In Situ Keratomileusis." Like its tangible counterpart, LASIK eye surgical treatment is another form of vision correction. The only difference is that with this kind of surgery, one's vision is fixed permanently.
With LASIK eye surgical treatment, the refractive mistakes in the cornea are permanently transformed. This can be done utilizing an "excimer laser."
The main purpose of this surgical treatment is to produce a threadlike, rounded "flap" in the cornea using a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is lastly reformed, allowing much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing popularity of LASIK eye surgical treatment, there are still disadvantages that people need to know. Most likely, the primary factor why this type of eye surgical treatment has become well accepted is since the majority of its cases had achieved success.
However, in spite of its success, there are still some downsides. Here is the list:
1. It is an operation used to the most sensitive part of the eye
Since LASIK eye surgical treatment includes the operation of the retina, which is one of the most delicate portions of the eye, the majority of people state that the operation can be extremely dangerous.
Simply puts, a simple error might almost trigger an person's lifetime loss of sight. It read more is crucial to think about lots of elements prior to choosing whether LASIK eye surgical treatment is the best restorative procedure one has to go through.
2. It is not a best treatment
LASIK eye surgical treatment might remedy your vision however it does not necessarily mean that it can provide you a perfect vision. Even if analytical reports reveal that 70% of the patients might have 20/20 vision, this does not always suggest they have ideal vision.
Offered all these things, it can be deduced that, in spite of the popularity of the operation, LASIK might not always be the ideal eye surgical treatment the way many people view it
Alternatively, the evaluation of the structural part of the eye might be made in numerous methods. It should be well remembered that a patient with an eye problem might have other issues. Typically other physical conditions are primary and affect the eye as a consequence. The look of the eye can alert the client and the physician to difficulties in some disruptions of other parts of the body even prior to other symptoms provide themselves.
Like its tangible counterpart, LASIK eye surgical treatment is another type of vision correction.


Infoscitex Corporation and UtopiaCompression Corporation have SBIR project successes
Two SBIR success stories have been posted to the Publications section of this web site (see the Innovation success story folder).
Utilization of photovoltaics in the space environment requires the provision of coverglass materials to protect cells from corpuscular and ultraviolet (UV) radiation. Infoscitex Corporation, located in Waltham, Massachusetts, tuned the optical transmittance of candidate glass materials to take advantage of the near-UV region at the beginning of life (BOL) and end of life (EOL) cycles. Infoscitex’s optimized glass formulation provides improved UV/Visible light transmissivity and resistance to radiation-induced darkening compared to currently used coverglass. The Infoscitex coverglass was flown on the National Aeronautics and Space Administration's Materials International Space Station Experiment-7 (MISSE-7) as part of the active solar cell experiment. Application of the Infoscitex coverglass technology on satellites in high radiation orbits could enable longer mission lifetime, more available power, and lower weight requirements for the power system. The AFRL Space Vehicles Directorate manages this SBIR project.
Under another SBIR project, the Air Force requirement was to develop a practical and effective approach to maneuverless range estimation using monocular passive electro-optical sensors for use in Unmanned Aircraft Systems (UAS) Sense-and-Avoid systems. UtopiaCompression Corporation, located in Los Angeles, California, developed an analytically proven practical approach for maneuverless monocular passive range estimation, which represents a practical solution to this decades-old problem. Using this novel approach, accurate range estimates (~10 percent error) can be obtained for aircraft up to three nautical miles away without requiring any UAS maneuver. The maneuverless monocular passive ranging technology will have a transformational impact on integrating UAS in the National Airspace by removing a major technological barrier. This SBIR project is managed by the AFRL Sensors Directorate.

Thesis Defence: Intelligent Surveillance with Multimodal Object Detection in Complex Environments
March 22 at 12:00 pm - 4:00 pm
Yue Cao, supervised by Dr. Zheng Liu, will defend their thesis titled “Intelligent Surveillance with Multimodal Object Detection in Complex Environments” in partial fulfillment of the requirements for the degree of Master of Applied Science in Electrical Engineering.
An abstract for Yue Cao’s thesis is included below.
Defences are open to all members of the campus community as well as the general public. Please email firstname.lastname@example.org to receive the Zoom link for this defence.
Surveillance systems play a crucial role in ensuring public safety. With the advent of deep learning algorithms, these systems have evolved from passive monitoring tools that heavily relied on human operators, to advanced solutions capable of autonomously analyzing scenes with minimal human input. However, accurately detecting objects of interest in real-world scenarios presents a significant challenge due to the dynamic illumination and the varying sizes of objects. This research aims to enhance the accuracy and robustness of intelligent surveillance systems for object detection in complex environments by integrating two complementary sensor data: visible light (RGB) and infrared (IR) images.
First, a multimodal detection framework is proposed building upon the Faster R-CNN architecture, which is capable of integrating features from both RGB and IR images for enhanced object detection. Following this, Poolfuser, a transformer-based fusion module, is introduced and incorporated into the detection framework to fuse features from various modalities from spatial perspective. This approach emphasizes the critical features for target detection. Experimental results show that the multimodal framework equipped with Poolfuser significantly outperforms unimodal detectors and other competing multimodal approaches in terms of detection accuracy in complex environments.
Secondly, to enhance both the efficiency and accuracy of the detection model without increasing computational complexity, a CNN-based lightweight fusion module named CSSA is introduced. This module is designed to fuse the input features from both the spatial and channel perspectives. Furthermore, CNN-based architecture enhances the generalizability of CSSA across datasets of varying sizes. The experimental results demonstrate that the CSSA module can further improve the detection accuracy without affecting the real-time performance of the detection framework.
Finally, considering the impact of other components, such as the backbone network and the loss function on detection performance. This study further optimizes the CSSA-based multimodal detection model and introduces CSSA-Det. CSSA-Det shows improved object detection performance over CSSA and other state-of-the-art multimodal frameworks, particularly in the accuracy of bounding box localization.

Volvo Concept Coupé – Cool Hunting… – a grouped images picture – Pin Them All
The code light is a lamp on the vehicle that lights up on the vehicle's nameplate. This helps to identify the specific license number that DMV has on file for your vehicle. The factory light source for most vehicles is a traditional light bulb with halogen lamp that provides a glow glow. Because of how the rating plate is designed or how much light is produced from the light, it may not be appropriate to meet the expectations of some car enthusiasts who want more output. There are two ways to drastically improve the appearance and output of your vehicle's sign lights. This article will explain the benefits and options available to make the LED light look.
LED stands for LED which is a semiconductor that produces light when electricity is introduced into its circuit. LED lamps provide much more lumens output per power consumed, which makes them much more efficient when converting electricity to visible light output. In essence, the LEDs are much brighter than ordinary halogen bulbs that are equally large. They are also more reliable than ordinary light bulbs due to the fact that there are no moving parts or components that decompose over time. LED lamps often last up to 50,000 hours in ideal working conditions. In addition to having all these advantages, LED lamps are also available in different colors and shades. The legal color of the license plate light application is white and yellow, but if you feel adventurous, you can choose the other exotic colors that LED lights can offer, eg. blue, red or the like.
The LED replacement lamp is the most common way to get the benefits of LED lights. LED replacement lamps are essentially what the name suggests; a similar lamp that the vehicle uses, but an LED version instead. Most LED lights have LEDs placed around the lamp to spread the light just as the factory lamp would. Lamps with LED lights are limited to the type of LED used and how much they are on the lamp itself. While most LED plate lamps provide enough light for most, it may not be enough for others. This leads us to the next type of LED light that is available for the nameplate that is the replacement unit.
The other way to get the benefits of LED is to buy a direct-fit LED lamp. For many vehicles, the factory lamp is located inside a larger unit that uses a plug and socket to hold it in place. This entire unit can be replaced with an LED equivalent that uses the factory network to power it up. These types of light can offer much more light output than the usual LED lamp replacement because of the particular design of the housing and the number of LEDs used.
In conclusion, if you need a brighter signboard, the best way to get this done is to use either an LED lamp replacement or an LED mount. both are wonderful and do a good job, but the latter is brighter. The advantages that LED lamps offer over light bulbs with halogen lamps are very obvious. There is no doubt that LED lights are the primary choice for factory lights on many vehicles such as Audi, Mercedes-Benz, BMW, Lexus, Cadillac and more.


The glass of shower room is white crystal glass
when all kinds of exquisite shower room products are gradually loved by consumers, the self explosion problem of tempered glass in shower room has been puzzling consumers. So, how to make the shower glass safer? This is a focus of social concern. Some experts said that the self explosion of tempered glass cannot be avoided, but the self explosion rate of tempered glass can be reduced to 1 in 10000 by using new products such as white crystal glass, which fundamentally solves the problem of self explosion of tempered glass. At present, the self explosion rate of ordinary tempered glass is ‰, while that of white crystal glass is only 0. Therefore, white crystalline glass is the lowest and safest glass in the world at present
Xu Wuyi, an expert of wangwenyong Industrial Glass Association of China building glass and DSM and the technical director of engineering glass of CSG group, pointed out that although the self explosion of tempered glass cannot be avoided, the self explosion rate of white crystal glass produced by special process can be greatly reduced. "After the ordinary white glass is hardened, a microcomputer sends a beam movement command according to the value set before the experiment. The self explosion rate of the universal experimental machine is 3 ‰ -5 ‰, while the white crystal glass is a highly transparent low iron glass. Due to less impurities, the self explosion rate can be reduced to less than 0.1 ‰."
white crystal glass adopts the world-class magnetic beneficiation process to remove impurities such as iron and nickel from raw materials. The composition is more uniform, the glass structure is more stable, and the self explosion rate is 10 times lower than that of ordinary tempered glass, thus making the shower room safer. At the same time, through aviation grade float deep processing, through the test of low temperature and high temperature resistance, white crystal glass has the advantages of acid resistance, corrosion resistance, mold resistance and durability compared with ordinary tempered glass without reducing the light transmittance
in view of the high-quality and multifunctional characteristics of white crystal glass, many well-known buildings use white crystal glass, such as Beijing bird's nest, water cube, Chinese History Museum, National Grand Theater and so on. Leiberton shower room is the only enterprise in the industry that adopts white crystal glass for its full range of products
white crystal glass is not only the best choice for large buildings, but also the best choice for shower rooms
it brings more opportunities to enterprises like Ashland all over the world


AI powered smart glasses from LAWK smash funding target on Kickstarter
Smart glasses with augmented reality display can overlay ride data and provide on-command information from ChatGPT assistant
Junior Tech Writer
LAWK has smashed its Kickstarter campaign for its AI powered augmented reality glasses
The cycling world is really embracing advancements in technology, with recent developments including a ChatGPT AI-based coaching platform from Whoop and aerodynamic optimisation sensors that can potentially rival wind tunnel testing. The future looks to be even closer now, with LAWK looking to launch a pair of very futuristic 'smart' glasses.
The LAWK ONE AR glasses feature a heads-up style display that can be used to present a multitude of metrics, from speed and power to navigation. The idea behind this is to overlay the data you want, where you would naturally be looking, preventing the need to look down at a head unit.
LAWK has designed the glasses to meet IPX4 certification requirements, making them suitable for use in rain showers and able to deal with sweat from workouts.
LAWK ONE offers riders a head up display of training and navigation metrics
The LAWK ONE also features the ability to capture pictures and videos with the built-in 8MP camera that can either be controlled via a dedicated button on the glasses or by voice command. Along with the data display and camera, the glasses feature integrated speakers that can be used for music whilst training or for notifications when paired with a smartphone.

A key feature the brand has invested in, with input from medical experts, is what it's calling ‘Binocular Waveguide Technology'. The issue with some AR systems is that the device only projects the overlay onto one lens of the glasses, resulting in a focal discrepancy between eyes that can lead to dizziness and eye fatigue.
LAWK's technology projects virtual information separately onto each lens, which is designed to enhance depth perception and provide a more realistic viewing experience.
Binocular waveguide technology has been used to prevent headaches and dizziness associated with some AR tech
Following the recent theme of the cycling world starting to embed the power of AI into products, the LAWK ONE glasses will offer a virtual assistant, powered by ChatGPT, that will allow you to ask questions on the move and have the answers read to you.
The power of AI in training is only just starting to be used but it is an exciting area to keep an eye on. On the topic of smart glasses, it was interesting to note that Apple CEO Tim Cook recently visited the Jumbo-Visma team and hinted that the tech giant's Vision Pro mixed-reality headset could be developed for cyclists in the future.
Originally LAWK had listed its glasses on Kickstarter with a target of £8,209. However, with an end date to reach funding of 25 November, the campaign has already generated £17,860 of pledges.
LAWK is anticipating that shipping of the product will begin in December 2023 with up to a 40% discount for pledges on Kickstarter.
Are AR glasses something that you can't wait to get your hands on?
Would you wear the LAWK ONE instead of using a typical head unit? Is wearable tech something that you will be welcoming with open arms, or should it remain in the world of science fiction? Let us know in the comments below.

The Veterinary Clinic Stuttgart possesses a completely equipped eye operating room with a high-class Zeiss operating microscope, an eye laser, a phaco machine, a cryo device, a modern anesthesia device and a system for the monitoring of the delivery of anesthetics, as well as all the microinstruments required for interventions in the interior of the eye.
Specialists define grey star or cataract as opacity of the crystalline lens, which leads to the nebular deterioration of eyesight and increased sensitivity to glare. The reasons are hereditary conditional lens opacities, lens opacities as a consequences of diabetes (increased blood sugar level), age-related opacities or the result of injuries and inflammations of the eye. The only treatment option is operation.
During the operation, the opaque lens is removed through a cut several millimeters long made using ultrasound and an artificial lens is inserted into the eye.
The modern and gentle operation technique we use almost always leads to a very good visual result.
The burden on the patient is low and the surgery can be also performed at an old age.

Digital Eye Strain? Tell me more.
That headache you’re coming home with? Yeah, it could be because Bill from accounting still hasn’t figured out how to stop “Replying All.” Or maybe it’s because your boss called the third meeting today that could have (should have) been an email. But ever stopped to consider it could be your computer screen? Every day, most of us spend over 10 hours sending emails, scrolling through Instagram, or admitting that yes, we’re still watching, when Netflix calls us out. All that screen time adds up to tired eyes when we don't take a break and allow our eyes to relax its accommodation.
What is Blue Light?
We’re all familiar with UV rays- we’ve been warned for decades now to wear sunglasses outdoors. The sun emits a spectrum of light, which makes our eyes light sensitive. Indoors, we are constantly surrounded by light emitted from screens and LEDs, which happens to be a wavelength of blue. Thus, wearing blue light filtering coating on lenses help to reduce light sensitivity and glare from screens and overhead lights. We do know that it can cause changes to our sleep patterns at night, which can cause insomnia, but our blue light filtering coating can help!
What makes us different? We’re doctor-designed and want to help you make the smart choice for strong healthy eyes. Each lens block 50% of all blue light and 90% of the highest range, blocks UV light, and comes with anti-glare. Our lenses enhance font, reduce light sensitivity, and appear virtually clear without compromising clarity. It’s like seeing the world in HD.


How do Mem-Gems work?
Constructive interference of laser light brings your image to life
Space is like a three-dimensional pond surface
If you have ever looked at a pond, you may have noticed little waves on the surface. Light waves are electromagnetic waves, which means that instead of moving molecules of water around on a pond surface, they actually distort the electromagnetic field of space itself. And rather than being confined to a surface of a pond, light waves can travel in three-dimensions. Light waves are amazing!
All the photons are one wavelength
The smallest measurable unit of light (a single photon) is created when an electron (the little charged guy orbiting the nucleus of an atom) hops down in energy. In a laser, a light photon can trigger an adjacent electron to release a photon in a chain reaction called stimulated emission (the SE LASER). As a result of all the complicated physics going on in a laser, all the photons of light emitted by a laser are nearly the same color. Unlike most things we see in our day-to-day lives that reflect sunlight of all colors to varying degrees, a laser emits just one wavelength of light. That's why lasers have such a futuristic appearance that's unlike anything you see in normal sunlight.
LasersLasers are spatially coherent light sources. That means that they shine in one direction, so they can be bright even if you're far away from them. Your eyes have evolved to focus light to enable you to see. However, this also means that a laser beam can actually be focused by your eye to a small spot on your retina, and permanently damage your eye. Furthermore, sudden exposure can cause temporarily surprise and blindness that can be dangerous if driving a car or operating heavy machinery. However, there are some basic physics principles that can help us stay safe:
- The power of a laser increases its danger level because it will take less time to cause damage to the retina. Therefore, we recommend: use a low-power laser (Class II or less).
- Do not stare at any direct reflections, so don't shine a laser at a mirror, shiny metal, or other optically reflective surface. Project images onto diffuse specular surfaces such as a white painted wall.
- Do not intentionally stare at a laser beam. If something is uncomfortable, look away.

A Mem-Gem™ uses a specially patterned laboratory-grown sapphire to control the optical interference of light
Since we know that light is a wave, and lasers have just a single wavelength, we can use physics to control how that light will interfere. We use software to turn your image into a special pattern called a phase-mask that controls light. By perfectly tuning the surface of your laboratory-grown sapphire Mem-Gem™ so that some areas create destructive interference and other areas create constructive interference, and repeating this process millions of times, we can build up a diffractive optical element that will project an image under laser light illumination. Each pixel in the Mem-Gem™ represents one Fourier mode of the resulting image projection, and that's why your image is hidden in sunlight. Similar to how musicians in a symphony orchestra create sound waves to celebrate music, we believe that Mem-Gems™ use light waves to celebrate the memory that you wish to treasure!


@seetheleaves: Glad to have helped.
@David: Thanks for pointing that out. I did not consider the intensity of light in my explanation. Mirrors that are "perfectly" flat, and therefore perfectly reflective are very, very rare, and so most mirrors (and lenses too) will "lose" some of the light (in the case of mirrors, some light is transmitted into them; in the case of lenses, some light is reflected and never reaches the eye) and the resulting image is not as intense (or as "sharp") as the actual object. But if I'm not mistaken, the difference is greater in lenses (like glasses) than in the average mirror, which tends to reflect light pretty well.

The HT7700 with Dual-Mode objective lens features superior high-contrast and high-resolution image quality together with analytical capabilities for biomedical and materials science. Digital design and sophisticated automation increase throughput for both novice and advanced users. Configure the HT7700 to meet all of your advanced sample analysis needs.
Critical sample features can be easily identified in the viewing screen camera image on the LCD monitor while operating in ambient light.
All saved images are stored in an image database where the thumbnail of the image can be viewed.
Each thumbnail image contains the microscope settings used when the image was captured.
When the operator clicks on any thumbnail image and selects “auto drive”, the specimen stage is automatically driven to the position where the image was captured.
The whole-view function allows a whole image of the grid to be acquired and displayed in the stage operation window. The micro-trace function stores and displays the movement path. This allows the operator to easily differentiate between examined and unexamined areas of the specimen.
Image navigation allows the storage of up to 100 stage coordinate positions and tilt angles. When a saved location is recalled, the instrument drives the specimen stage to the saved coordinate position and tilt angle.
API is essential for imaging beam-sensitive specimens and for stabilizing specimens to prevent drift.
Operators can select from several modes, as shown below (Whole scan, Frame scan, and Area Scan), to optimize sample stabilization results.
By means of API, the contrast of examined areas (left) matches the surrounding embedded tissue and resin (right). API effectively minimizes damage and specimen drift during observation.
Auto multiple frame function and Auto panoramic function capture and delineate seamless panoramic images for large format results.
Double-Gap Objective lens design for HC and HR
The highly stable Hyper stage of the HT7700 with ±70° automated tilt capability, coupled with Hitachi’s unique reconstruction algorithms . including Topography Based Reconstruction (TBR)-can be used to create high quality tomographic reconstructions.
The combination of double-axis tomography and Hitachi’s unique reconstruction software can be used to achieve 3D reconstructions with fewer artifacts and more accurate results.
Both Bright Field (BF) and Dark Field (DF) detectors can be added to the HT7700 for STEM analysis.
BF-STEM provides better contrast and image sharpness due to reduced chromatic aberration.
Furthermore, scattered electrons are detected with high sensitivity by means of DF-STEM, resulting in better contrast for low-Z specimens.
When an EDX detector is included, multiple elemental maps can be recorded simultaneously.
EXALENS is a newly designed objective lens for the HT7700.
By achieving a smaller spherical aberration coefficient (Cs), a resolution of 0.144 nm (lattice, accelerating voltage : 120 kV) is obtained.
EXALENS excels at high resolution imaging at lower accelerating voltage, facilitating analyses of soft materials, carbon-based nanomaterials and polymers.
In addition to various Hitachi holders (below), specialty holders for low temperature, heating, in-situ and other experiments are available from several manufacturers.

Ray-Ban is an extremely iconic brand that almost everybody world wide has heard of.
It all started in the 1930s, when Lt. John McCready returned from a hot air ballooning trip. Upon his return, he exclaimed that his eyes had suffered irreversible damage from the sun. Being in the US Air Force, he commissioned a pair of glasses that would protect his eyes from the sun as well as look good. German brand Bausch & Lomb won the contract and created the Ray-Ban brand in the process. Other pilots in the Air Force also wanted these glasses as they would be flying at high altitudes and needed protection, as well as comfort and style. Ray-Ban went on to publicly distribute the glasses, these were the first aviators. The company has now gone on to became the worlds number one brand, both in sunglasses and optical glasses, which were only introduced in 2003.
The Ray-Ban RX5150 is almost similar in style to the classic Wayfarer, though smaller in size. These glasses are extremely stylish and recognisable, though designed for those who may not be able to carry off a bigger, more brash, frame. The frame is fairly thick, but not overly so, and create a nice focal point to the face. The frame is fairly straight at the top and not catty, so will suit both men and women equally as well.
Most lenses can be fitted to this frame. Single vision and varifocals are available, as are Transitions lenses for those who would prefer not to have the hassle of switching to prescription sunglasses when they venture into the sun. The lenses are available in four thicknesses, with thinner lenses recommended for those with medium to high prescriptions to stop them looking too bulky and visually unattractive. Coatings are available, with all lenses recommended to have anti-glare and scratch resistant coatings to prolong their life as well as stop unnecessary glare. Premium coatings include dust and water resistance which can mean a clear, unobscured view at all times, and smudge proofing.

Could the same infrared technology that’s used by security firms to detect trespassers be used to spot carpool lane violators? Not yet, says new research sponsored by MnDOT, which shows that to consistently detect passengers through windshield glass, the system would require a laser that might harm people’s eyes.
“Some vendors have proposed significant investments in sensing technology for HOV/HOT lane enforcement,” said Nikos Papanikolopoulos, Professor, University of Minnesota Department of Computer Science and Engineering. “This research demonstrated that it’s not safe, so the tests saved a lot of money and protected the well-being of drivers.”
“Development is still continuing in the industry, so we will cautiously evaluate sensing technologies as they come along,” said Brian Kary, MnDOT Freeway Operations Engineer. “This research gave us a solid base of knowledge about what we’ll be looking for and what we need to avoid.”
Papanikolopoulos served as the research project’s principal investigator, and Kary served as technical liaison.
What Was the Need?
High-occupancy vehicle/high-occupancy toll (HOV/HOT) lanes have gained popularity in recent years as a way to address highway congestion in urban areas. However, enforcing the provisions that either prohibit or charge a toll to single-occupant vehicles in HOV/HOT lanes can be challenging. Currently, enforcement is handled by law enforcement officers, but this is a labor-intensive process that can’t catch every violator and can create a traffic safety hazard.
Obtaining technology to assist officers with enforcement is a goal for MnDOT and many other agencies that operate HOV/HOT lanes, and several manufacturers are working to develop enforcement cameras. But this has proven to be a difficult task. Window tinting and glare from sun-light can thwart common sensing technologies like video cameras and microwave radar (commonly used in speed limit enforcement). Previous research using near-infrared sensors has shown promise, but none has produced completely successful results.
This study tested Honeywell’s Tri-Band Infrared (TBI) sensor, which was originally used to automatically detect intrusions at high-security entrance gates. In addition to a black-and-white camera and an illuminator, the TBI has two co-registered near-infrared cameras. The system takes advantage of the fact that human skin reflects infrared light much more effectively at wavelengths below 1400 nanometers. The TBI’s infrared cameras are sensitive to different wavelengths, one below and one above that threshold, and fusing the images from these two cameras makes silhouettes of faces more prominent.
What Was Our Goal?
The goal of this project was to evaluate whether the TBI sensor is suitable for HOV/HOT lane enforcement applications.
What Did We Do?
Investigators first tested the sensor outdoors on oncoming vehicles with known positions that ranged from 25 to 140 feet from the sensor. These tests demonstrated that the sensor had limited ability to penetrate modern vehicle glass, possibly because the system’s illuminator component was ineffective.
Investigators purchased two infrared lasers providing illumination at wavelengths of 1064 nanometers and 1550 nanometers to increase the TBI sensor’s ability to detect people through windshield glass. Then they conducted indoor tests to compare the impact of these illuminators with that of the original illuminator: With a test subject holding front passenger windows from several manufacturers in front of his face, the lasers were aimed at the subject while the TBI attempted to detect him.
Finally, investigators conducted outdoor tests using the TBI to detect people in three test vehicles from the front and the side under both sunny and cloudy conditions. These tests were conducted both without illumination and with the aid of high-power incandescent spotlights modified to output infrared light, and with the sensor at several different distances from the vehicles.
What Did We Learn?
The indoor tests demonstrated that when aided by supplementary illuminating lasers, the TBI sensor was capable of detecting humans through commonly manufactured vehicle window glass.
However, to achieve successful results, these lasers must operate with high power in a narrow range of wavelengths. Despite operating outside the visible spectrum, they can damage human eyes when operating at the necessary power level to enable effective detection through glass. While investigators conducted this project’s indoor tests with adequate protection, there is currently no way to ensure safe usage of the lasers in real-world applications.
In the second outdoor tests, the unilluminated sensor successfully detected a passenger only once out of 24 attempts. With illumination, the sensor successfully detected people in some cases, particularly when there was no direct sunlight or reflective glare. One surprising discovery was that high-band (above 1400 nanometers) infrared light penetrated window glass more consistently, even though the low band had more spectral energy.
Due to safety concerns about using the illuminating laser at a high enough power to penetrate all windshield glass, the system is not suitable for HOV/HOT lane enforcement. There is some indication that sensor technology has improved since the release of the TBI, and MnDOT will continue to monitor industry developments, but it has no current plans to pursue using infrared cameras for this application.
The technology may be suitable for other sensing applications that do not require high-power illumination. For example, the sensors might be useful in systems that provide information to drivers in real time, such as applications that identify available truck parking spaces in rest areas or that alert drivers to the presence of workers in work zones.
