    Abstract: Described herein are computer-implemented methods, computer-readable media, and computer systems for the establishment of data communications between devices based through the use of acoustic signals. A first device transmits an acoustic signal, which is received by one or more other devices. The first device and the receiving devices establish a new communications network (e.g., create a new Wi-Fi network and/or peer-to-peer wireless network), or form/establish a grouping within a pre-existing communications network to which the devices are all connected. The devices can then exchange data over the new communications network or within the grouping on the pre-existing network. Also described herein are techniques for a device to determine its distance and/or other positioning information relative to another device, using acoustic and/or RF signaling.

    Abstract: A wireless power system may have a wireless power transmitting device and wireless power receiving devices. The wireless power transmitting device has wireless power transmitting circuitry with coils to transmit wireless power to wireless power receiving devices. The wireless power receiving devices are placed on the wireless power transmitting device in an order. Batteries in the wireless power receiving devices are charged based at least partly on the order. Power allocation is based on utilization factor information such as information on a power draw associated with each of the power receiving devices. Measurement circuitry in the wireless power transmitting device is used to gather impedance images from the coils. Changes in the impedance images are used to temporarily halt power transmission. Power transmission is resumed depending on whether in-band communications are lost or are maintained.

    Abstract: A wireless power transmitting device transmits wireless power signals to a wireless power receiving device. To detect foreign objects, the wireless power transmitting device has an array of temperature sensors. The array of temperature sensors may include temperature sensor components such as temperature sensitive thin-film resistors or other temperature sensitive components. A temperature sensor may have thin-film resistors formed on opposing sides of a substrate. The thin-film resistors may be formed from meandered metal traces to reduce eddy current formation during operation of the wireless power transmitting device. Signal paths coupling control circuitry on the wireless power transmitting device to the array of temperature sensors may be configured to extend along columns of the temperature sensors without running along each row of the temperature sensors, thereby reducing eddy currents from loops of signal routing lines. Some temperature sensors may have multiple components coupled to a common temperature sensing pad.
