Abstract: The present disclosure generally relates to displaying information related to a physical activity. In some embodiments, methods and user interfaces for managing the display of information related to a physical activity are described.

Abstract: Systems, methods, and apparatus are disclosed for determining bore sight error. An apparatus may include an optical lens and a collimated light source configured to emit a beam of collimated light having a first wavelength, where the beam of collimated light passes through the optical lens and parallel to an optical axis of the optical lens. The apparatus may further include a position sensitive detector configured to receive the beam emitted by the collimated light source, and identify a first position of the beam relative to the position sensitive detector. The apparatus may also include a processing device configured to generate a bore sight error metric based, at least in part, on the first position identified by the position sensitive detector. The bore sight error metric characterizes a difference between an actual position of a target object and a perceived position viewed by the optical lens.

Abstract: In one aspect a power amplifier comprises a first plurality of laser disks disposed in a first vertical plane and a second plurality of laser disks disposed in a second vertical plane, opposite the first vertical plane, wherein the plurality of laser disks are disposed in a central horizontal plane, and a first plurality of reflecting mirrors disposed in the first vertical plane and a second plurality of reflecting mirrors disposed in the second vertical plane, wherein a first set of reflecting are disposed in a lower horizontal plane and a second set of reflecting mirrors are disposed in an upper horizontal plane, wherein respective laser disks and reflecting mirrors adjacent along an optical axis are positioned to provide a 1:1 imaging system therebetween. Other aspects may be described.

Abstract: A passive, real-time obstacle detection system is provided that determines the presence of small, curvilinear objects such as power lines. The system generally comprises a payload system having an infrared image detection system, a crew interface having a display for the images, and software algorithms that perform image processing on the pixel images. The software algorithms employ Cellular Automata (CA) techniques to resolve the direction vectors of sub-pixels, and as such, line segments are produced that are subsequently linked for display to the flight crew. The CA techniques are further based on the “Game of Life” model, wherein local rules are used to determine how pixels evolve, or propagate along a line. The linked lines are then displayed for the flight crew so that evasive maneuvers can be performed as necessary.
