Query: Data Acquisition System for a Distributed Smartphone Cosmic Ray
  Observatory   A scientific instrument comprised of a global network of millions of
independent, connected, remote devices presents unique data acquisition
challenges. We describe the software design of a mobile application which
collects data from smartphone cameras without overburdening the phone's CPU or
battery. The deployed software automatically calibrates to heterogeneous
hardware targets to improve the quality and manage the rate of data transfer,
and connects to a cloud-based data acquisition system which can manage and
refine the operation of the network.
