  • Patent number: 10277058
    Abstract: Certain aspects of the present disclosure are generally directed to apparatus and techniques for protecting electronic devices that may be prone to damage by wireless charging fields. For example, the apparatus may include a wireless charging circuit configured to selectively generate a wireless charging field and an impedance detection circuit coupled to the wireless charging circuit and configured to detect an impedance change corresponding to the wireless charging field. In this case, a proximity detection circuit may selectively detect proximity of one or more electronic devices that are prone to damage by the wireless charging circuit. In some aspects, detecting the proximity of the one or more electronic devices is activated based on detecting the impedance change, and wherein generating the wireless charging field comprises reducing a transmit power of the wireless charging field based on detecting the impedance change.

  • Patent number: 10274631
    Abstract: A foreign-object detecting device includes a first coil, a second coil arranged adjacent to the first coil and having the same winding direction as that of the first coil, and foreign-object detecting circuitry. The foreign-object detecting circuitry outputs a first detection signal to an outside or inside terminal of the first coil, outputs a second detection signal having an inverted phase to an outside or inside terminal of the second coil, causes one of the first and second detection signal to flow clockwise, causes the other detection signal to flow counterclockwise to generate a combined magnetic field across a center of the first and a center of the second coil, measures an amount of change in an impedance value of the first or second coils, and determines that a foreign object is present within the combined magnetic field, based on the amount of change.

  • Patent number: 10277056
    Abstract: A wireless charging system including a transmitter and a receiver. The transmitter is formed of a coil of wire that includes a first loop portion, a second loop portion, and a crossing portion. The crossing portion electrically couples the first loop portion and the second loop portion such that when current is generated in the coil, electrical current flows through the first loop portion in a different rotational direction than in the second loop portion. The receiver is formed of a ferromagnetic core and multiple (e.g., three) coils disposed about the ferromagnetic core. Each coil may be disposed about a different axis of the core such that current may be induced in at least one of the coils by a magnetic field in any direction.

  • Patent number: 10270260
    Abstract: Power transmitting unit (PTU) usable with a wireless power transfer system to supply power and maintain a control signaling link to a local power receiving unit (PRU). A cross-connection circumstance between the PTU and a remote PRU is determined, where a control signaling link between the PTU and the remote PRU is established in an absence of power transmission to the remote PRU from the PTU. In response to the cross-connection circumstance, the control signaling link with the remote PRU is terminated while the supply of power and the control signaling link with the local PRU is maintained. In a related embodiment, a wrong-placement characteristic where power is transferred to a rogue local PRU in an absence of a control signaling link with that PRU, is detected. In response, the supply of power is maintained for at least a waiting period.
