Abstract: An optical tracking system comprises an array of point source emitters that output respective optical emissions, and a plurality of angle of arrival sensors. Each sensor comprises one or more optical elements and a focal plane array (FPA), with the optical elements arranged to resolve the optical emissions into one or more linear patterns on the FPA. A processing system in communication with the sensors establishes the orientation and position of each of the optical emitters using the linear patterns. A headgear tracking system employs point source emitters on a piece of headgear, with front and rear arrays of angle of arrival sensors located in an aircraft cockpit; a processing system in communication with the sensor arrays establishes an orientation and position for each of the optical emitters on the headgear.

Abstract: The light-emitting diode (LED) display system and method are provided. A LED display structure houses a quantity of LEDs. A control unit is in communication with the LED display structure. An audio output system supplies at least one audio signal to the control unit, wherein the control unit processes the at least one audio signal and transmits at least one processed audio signal to the LED display structure. A quantity of light is emitted from at least a portion of the quantity of LEDs is based on the at least one processed audio signal. A selection device is in communication with the control unit and controlling selection of at least one display mode of the LED display structure. At least one power supply supplies a quantity of voltage to at least one of the LED display structure, the audio output system, the control unit and the selection device.
