Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for wireless power transmission. A wireless power transmission apparatus may transmit multiple wireless power signals to a wireless power reception apparatus configured to combine the power from the multiple wireless power signals. The wireless power reception apparatus may provide a combined wireless power signal to a load, such as a battery charger or electronic device. In some implementations, each set of primary coil and secondary coil may utilize low power wireless power signals (such as 15 Watts or less) in accordance with a wireless charging standard. By combining power from multiple low power wireless power signals, the wireless power reception apparatus may support higher power requirements of an electronic device. Multiple communication channels may be established between the wireless power transmission apparatus and the wireless power reception apparatus.

Abstract: A wearable audio output device is in communication with a first device and with a second device that is different from the first device. While outputting first audio from the first device, the wearable audio output device receives a first input corresponding to a request to output second audio from the second device; and, in response to receiving the first input: in accordance with a determination that the second audio from the second device satisfies audio priority criteria with respect to the first audio from the first device, the wearable audio output device: ceases to output the first audio from the first device; outputs the second audio from the second device; and causes the first device to display a first alert indicating that the first audio from the first device is not being output by the wearable audio output device.

Abstract: An apparatus and method for inductive wireless power transfer. The apparatus comprises an array of resonators. At least adjacent resonators in the array are mutually electromagnetically coupled. For each resonator in the array, a resonance frequency of the resonator is configured in dependence on the number of neighbouring resonators that are coupled to the resonator and/or the strength of coupling with each neighbouring resonator using the formula f 0 = fd * V(1 - G * k1) where fo is the resonance frequency of the resonator, G is the number of nearest neighbours of the resonator, k 1 is the coupling coefficient which is defined as the ratio of mutual inductance between the neighbouring resonator to the self-inductance of the resonator, and fd is a design frequency.

Abstract: A wireless power system has a wireless power transmitting device and a wireless power receiving device. The devices in the wireless power system may communicate using in-band communication. The wireless power transmitting device may transmit data to the wireless power receiving device using frequency-shift keying (FSK) modulation. The wireless power receiving device may transmit data to the wireless power transmitting device using amplitude-shift keying (ASK) modulation. While transmitting data to the wireless power receiving device using FSK modulation, the wireless power transmitting device may monitor for ASK modulation from the wireless power receiving device. In response to detecting the ASK modulation from the wireless power receiving device, the wireless power transmitting device may abort the FSK data transmission and process the detected ASK modulation to receive data from the wireless power receiving device.
