摘要： A wireless power system for vehicle wheels is described. The system includes a magnetic field generator, e.g., a permanent magnet, embedded or disposed in a fixed position, e.g., in a wheel well or brake caliper(s), and a wireless power receiver embedded or disposed in a wheel rim or wheel trim. As the wheel rotates and receiver antenna(s) cross a flux path produced by the power transmitter, an alternating current signal is produced at the receiver, which is converted to a direct current signal, regulated, and delivered to various electronic components in the vehicle wheel. The received power can be used to charge a battery or power light emitting diodes (LEDs). A wireless communication module embedded in the vehicle wheel can be used to wirelessly control and monitor the electronic components, e.g., to change intensity or strobe periodicity of LEDs or monitor sensors.

摘要： Systems and methods for wirelessly charging one or more electronic devices in a vehicle (e.g., electronics in the vehicle seat or charging occupant devices from charging system embedded in the vehicle) are described. One method includes receiving a direct current (DC) signal from a power source, amplifying the received DC signal to generate an amplified alternating current (AC) signal, monitoring an internal signal in the power amplifier and adjusting one or more properties of the power amplifier in response to the monitored signal. The amplified AC signal is transmitted by one or more transmit antennas

摘要： The disclosed technology provides a resonant inductive receiver integrated in a wireless power receiver accessory such as a phone case and configured to provide power to an electronic device such as a mobile phone. The power to charge the electronic device is received from a pass-through connector coupled to the receiver accessory when a wired charger is plugged into the connector, or received from a wireless power transmitter when a wired charger is not plugged into the connector and the wireless power receiver is proximate to the wireless power transmitter.

摘要： Methods, systems, and devices are disclosed for wirelessly charging electronic devices. In one aspect, a wireless charging transmitter device includes a three-dimensional coil array electrically coupled to a power source and structured to include two or more coils to produce an electromagnetic field that emanates from the three-dimensional coil array, in which the coils are arranged such that at least two coils are perpendicular to each other to direct the electromagnetic field. The wireless charging transmitter device is operable to wirelessly charge an electronic device by providing the electromagnetic field at a receiver coil of the electronic device to convert the electromagnetic energy to electrical energy to power the electronic device.
