Abstract: Embodiments include devices and methods for maintaining control of a robotic vehicle when control signals from a main controller are lost. A detector circuit may monitor signals from the main controller to an electronic speed controller (ESC) to detect a loss of valid control signals. The detector circuit may cause an auxiliary controller to begin issuing motor control signals to the ESC in response to detecting a loss of valid control signals. The auxiliary controller may be configured to issue motor control signals to the ESC according to a pre-loaded set of motor control instructions. The pre-loaded set of motor control instructions may be received from the main controller and/or may be configured to cause the auxiliary controller to issue motor control signals to the ESC that control motors in a manner that causes the robotic vehicle to enter a safe mode of operation or execute a particular maneuver.

Abstract: Disclosed is a current sensor that senses current flow in a conductor by coupling a first magnetic field generated by the conductor to a sense element. The current sensor includes a shield including a first material that sandwiches the sense element to define a stack and a second material that sandwiches the stack. The shield is configured to generate a second magnetic field, responsive to a third magnetic field external to the current sensor that opposes the third magnetic field. The shield is further configured to prevent production of a magnetic field that opposes the first magnetic field generated by the flow of current in the conductor.

Abstract: An aspect of this disclosure is an apparatus for transmitting power wirelessly. The apparatus comprises a detection circuit and a processor. The apparatus also includes a power amplifier driving an antenna circuit of flexible antenna(s) configured for wireless power transfer. The processor determines that at least one measured variable of the power amplifier falls outside of a corresponding threshold range, indicative of a deformation of a physical shape of one of the flexible antennas or indicative of misalignment of the flexible antennas from a power receiver. The processor further commands the power amplifier to transition to a first power mode from a second power mode based on the determination that at least one of the measured variables falls outside of the corresponding threshold range. The antenna circuit in the first power mode transmits power at a power level less than the power level in the second power mode.

Abstract: A wireless power transmitter that provides wireless power via a magnetic field includes electrical connections for a driving signal and a plurality of coupler loops that divide the current generated by the driving signal. The transmitter can be tuned to provide a distributed magnetic field that is more evenly distributed over the transmitter pad. The currents through different coupler loops can be controlled by the relative impedances of the coupler loops. The coupler loops can take on various shapes, such as substantially concentric circular paths and they may overlap. Impedances can be designed using one or more capacitances. Capacitance between coupler loops can be provided. Feed capacitors might be provided at the electrical connections.

Abstract: An apparatus is disclosed that implements ultrasonic power transmission with impedance detection. In an example aspect, the apparatus includes an array of ultrasonic transducers and an acoustic-impedance detection system. The acoustic-impedance detection system is configured to transmit an ultrasonic detection pulse from an ultrasonic transducer of the array. Based on the ultrasonic detection pulse, the acoustic-impedance detection system can determine an acoustic impedance at the ultrasonic transducer. Based on the acoustic impedance, the acoustic-impedance detection system can transmit an ultrasonic charging signal.

Abstract: Techniques for acoustic power coupling for mobile audio devices are described. In one or more implementations, a mobile audio device includes a device speaker with a membrane that produces audio output for the mobile audio device, an amplification circuit electrically connected to the device speaker, and a rechargeable battery electrically connected to the amplification circuit. In response to a deformation of the membrane by a force supplied by a force generator, an alternating (AC) voltage is produced on the amplification circuit. The amplification circuit optionally amplifies the AC voltage and converts the AC voltage to a direct (DC) voltage. The amplification circuit applies the DC voltage to the rechargeable battery to recharge the rechargeable battery.
