Abstract: Systems and methods for providing low latency and high bandwidth wireless data transport for various applications, such as virtual reality, augmented reality, or video applications. A wireless data transport system is provided that includes an electrically steerable antenna, such as a phased-array antenna, that is operative to selectively steer its beam based on control input. The wireless data transport system includes a tracking subsystem that is operative to track a mobile wireless device (e.g., head-mounted display (HMD), tablet computer, smart phone) as the mobile wireless device moves around in a tracked volume. The wireless data transport system utilizes the known position, orientation, or movement of the mobile wireless device receiving the data (e.g.

Abstract: Systems and methods for distributing power over a relatively long distance by sending high frequency alternating current (AC) over a transmission subsystem between a sender subsystem and a receiver subsystem. Power may be sent from the sender subsystem to the receiver subsystem over a transmission subsystem that includes first and second conductors, such as pair of shielded or unshielded wires twisted together. The sender subsystem may utilize a resonant converter to provide sinusoidal oscillation, which greatly reduces the radio emissions normally caused in DC systems due to high frequency current draws by a load. The receiver system may include a resonant converter or discontinuous conduction mode flyback converter, which provides DC power to a load.

Abstract: A method and apparatus for fault detection of series diodes in rectifiers is disclosed, wherein the voltages across one or both of the individual diodes, and/or the voltage across the pair of diodes are measured to determine a ratio between two of those voltages. The ratio is then analyzed to determine if a fault (e.g., a short circuit or an open circuit) is present. In some embodiments, circuitry can be included to compensate for the normal variations in diode characteristics (e.g., reverse leakage current, reverse recovery charge) between the pair of series diodes to minimize the potential for erroneous fault detection.
