Abstract: Systems and methods of present disclosure enable functional and molecular profiling with an incubation chamber that receives a well array and an imaging device in the incubation chamber. The well array has a sample of cells in at least one well. The imaging device captures a series of images of the filled well array during incubation in the incubation chamber and communicates the series of images to a processor. The processor detects each well in each image, localizes each well in each image, detects cells of the sample of cells in each well of each image, determines a number of cells in each well in each image based on the prioritization of the wells, tracks a relative location of each cell in each well, and determines cell-to-cell contact based on the relative location.

Abstract: A satellite system for optical communications such as a multi-access laser transceiver system. Up to six low Earth orbiting satellites send satellite data to a geosynchronous satellite. The data is relayed to a ground station at the Earth's surface. The earth pointing geosynchronous satellite terminal has no gimbal but has a separate tracking mechanism for tracking each low Earth orbiting satellite. The tracking mechanism has a ring assembly rotatable about an axis coaxial with the axis of the field of view of the geosynchronous satellite and a pivotable arm mounted for pivotal movement on the ring assembly. An optical pickup mechanism at the end of each arm is positioned for optical communication with one of the orbiting satellites by rotation of the ring.
