摘要： A transceiver assembly for a wireless power transfer system includes a transceiver system comprising a photodiode assembly, a voltage converter and a light emitting diode and a photodiode. The photodiode assembly may be configured to receive a high-power laser beam from a transmitter and to convert the high-power laser beam to electrical energy. The voltage converter may be configured to adjust an input impedance based on a voltage measure of the photodiode assembly so as to maximize power transfer from the photodiode assembly to an energy storage device electrically coupled to the voltage converter. The light emitting diode and the photodiode may be configured to enable free space optical communication with the transmitter. The light emitting diode may emit signals indicating a presence and a location of the transceiver to the transmitter at least when the energy storage device requires a charge.

摘要： An assembly for optical to electrical power conversion including a photodiode assembly having a substrate layer and an internal side, an antireflective layer, a heterojunction buffer layer adjacent the internal side; an active area positioned adjacent the heterojunction buffer layer, a plurality of n+ electrode regions and p+ electrode regions positioned adjacent the active area, and back-contacts configured to align with the n+ and p+ electrode regions. The active area converts photons from incoming light into liberated electron hole pairs. The heterojunction buffer layer prevents electrons and holes of the liberated electron hole pairs from moving toward the substrate layer. The plurality of electrode regions are configured in an alternating pattern with gaps between each n+ and p+ electrode region. The electrode regions receive and generate electrical current from migration of the electrons and the holes, provide electrical pathways for the electrical current, and provide thermal pathways to dissipate heat.

摘要： Control instructions are transmitted to receivers by modulating light sources to generate light beams that are modulated with digital data streams for inducing control instructions in the light beams. Each light beam is applied to a pixel shaper element of a pixel shaper assembly to produce a light pixel, each light pixel carrying the control instructions of the light beam, each light pixel having a perimeter defined by the pixel shaper element. The pixel shaper assembly combines the light pixels into an image without significant overlap or voids between the light pixels. The light pixels are directed toward a projector lens for transmission toward the receivers. In a receiver, an optical receiver detects a light pixel. A controller decodes the control instructions received in the detected light pixel and uses the control instructions to control a function of the receiver.

摘要： In a wireless optical network with multiple coordinators or other access points, the coverage area of coordinators may overlap. Interference in the communication between coordinators and devices may occur in these overlapping coverage areas. Various embodiments propose an automatic allocation of reserved time slots to coordinators. These time slots support the coordinators to advertise their presence without interference and enable a device to detect the presence of a neighbour coordinator in a single MAC cycle. Cooperation of coordinators can be supervised by a global controller to determine non-interfering time schedules whereby the coordinators rely on interference reports from the devices in the overlapping coverage areas. Fast detection allows fast re-scheduling of time slots in the wireless optical network in order to prevent interference when a device that enters the overlapping coverage area of two coordinators.

摘要： Embodiments relate to a local free space optical (FSO) terminal that transmits and receives optical beams. The FSO terminal includes a fore optic and a dispersive optical component. A receive (Rx) optical beam from a remote FSO terminal is received and focused by the fore optic to a Rx spot at a focal plane of the fore optic. A transmit (Tx) optical beam with a different wavelength forms a Tx spot at the focal plane and is collimated and projected by the fore optic to the remote FSO terminal. The dispersive optical component is positioned along optical paths of both the Rx beam and the Tx beam. Among other advantages, a wavelength dependence of the dispersive optical component laterally separates the Rx spot and the Tx spot at the focal plane.
