    Abstract: A coded localization system includes a plurality of optical channels arranged to cooperatively capture information from a scene. Each optical channel includes (i) a respective multi-pixel detector and (ii) a respective localization code, located between the respective multi-pixel detector and the scene, that modifies electromagnetic energy passing therethrough. Each localization code (i) includes at least one of an amplitude mask, a phase mask, and a polarizer, and (ii) differs from the respective localization code of each other of the plurality of optical channels.

    Abstract: An anti-collision system for a storage area comprises at least one emitter device (2), at least one receiver device (3), a signaller device and a control unit. The emitter device (2) can be coupled to a forklift (C) movable within the storage area and is configured to emit an optical signal. The receiver device (3) is installable at a ceiling of the storage area and is configured to monitor at least one transit zone (Z) of the storage area so as to acquire the optical signals (O) emitted therein. The control unit is configured to activate the signaller device as a function of the optical signals (O) acquired so as to generate an alert signal.

    Abstract: An inertial head-tracking system includes light emitting diodes (LEDs) and photoreceptors. The LEDs and photoreceptors are positioned around the environment and helmet respectively. A processor periodically receives measurements from the photoreceptors and resets inertial drift based on those measurements. Either the LEDs or the photoreceptors are constrained to a specified range to allow for more accurate drift estimation.

    Abstract: Method and system for directing RF energy from an active retrodirective antenna array including moving elements onto a target includes: receiving a beacon from the target by each element, the scattered beacon including an RF pilot signal imposed thereon, extracting the RF pilot signal from the received scattered optical beacon, dynamically measuring a distance to an area of optical beacon illumination on the target, calculating a phase utilizing the measured distance to the area of the target and a frequency of the extracted RF pilot signal, phase conjugating the RF pilot signal based on the calculated phase, and transmitting the phase conjugated RF signal towards the target; by each element, where the phase conjugated RF signal transmitted by each element add coherently at the area of optical beacon illumination on the target to enhance power density on the target.
