Abstract: A method and apparatus comprising a projector system and a structure connected to the projector system. The projector system is configured to project an image on an exterior surface of an aircraft. The structure is configured to be connected to the aircraft and has a shape configured to reduce an undesired airflow caused by the projector system when the aircraft is in flight.

Abstract: A system may include a spherical retroreflector that reflects incident light back in substantially the same direction as a light source; and a surface of the spherical retroreflector including a light modulator that modulates incident light from the light source in response to a stimulus and reflects a modulated light, wherein the light modulator is a variably reflecting backing of the spherical retroreflector.

Abstract: A multifunction light detection and ranging (LIDAR) system for aircraft or other applications may use autodyne techniques. An autodyne system can use a single laser source and a single detector. The autodyne technique can mix two signal beams to produce a “beat note” at the frequency difference between the beams. Autodyne detection can leverage photon counting to support significantly reduced system complexity. Reduced complexity may provide solutions with significantly reduced power consumption, lighter weight, smaller volume, and lower cost. The multifunction LIDAR system can detect and identify regions of weather hazards such as lightning storms, aircraft wake vortex, clear air turbulence, and wind shear. The multifunction LIDAR system may also be configured to measure aircraft air and ground speed in multiple dimensions as well as aircraft altitude.

Abstract: A method and apparatus for managing a programmable control panel for a vehicle. A number of first level control functions is assigned to the programmable control panel for the vehicle. A number of second level control functions is assigned to the programmable control panel based on a health of programmable control panels in the vehicle.

Abstract: Presented is a low-power retro-reflective communication system that reflects modulated light back in substantially the same direction as the light source using a retro-reflector. The light modulator in the retro-reflector modulates the light in response to a stimulus, such as an electrical communications stimulus or an environmental stimulus. In embodiments, the retro-reflector is a corner-cube retro-reflector and the modulator is one of the reflecting surfaces, or a spherical retro-reflector and the light modulator is a variably reflecting backing.

Abstract: Presented is a system and method for coordinating power usage of electrical devices on a power bus. In an embodiment, the system includes a power bus, a first electrical device that is able to intermittently draw power from the power bus, a second electrical device that is able to intermittently draws power from the power bus, and a means for sensing when the second electrical device is intermittently drawing power. When the second electrical device is intermittently drawing power, the first electrical device is inhibited from drawing power from the power bus.
