Abstract: A power transmitting device is disclosed comprising: one or more coils; at least one memory that stores computer-executable instructions; and at least one processor configured to access the at least one memory. The at least one processor may be configured to execute the computer-executable instructions to: cause to send to a first device a first load measurement request at a first instance and a second load measurement request at a second instance. The computer-executable instructions may cause the processor to receive a first load measurement associated with the first load measurement request and a second load measurement associated with the second load measurement request. The computer-executable instructions may cause the processor to determine a first average measurement of the first load measurement and the second load measurement. The computer-executable instructions may cause the processor to send to a second device a third load measurement request at a third instance and a fourth load measurement request at a fourth instance. The computer-executable instructions may cause the processor to receive a third load measurement associated with the third load measurement request and a fourth load measurement associated with the fourth load measurement request. The computer-executable instructions may cause the processor to determine a second average measurement of the third load measurement and the fourth load measurement. The computer-executable instructions may cause the processor to perform a load measurement of the one or more coils of the power transmitting device. The computer-executable instructions may cause the processor to determine a presence of one or more rogue devices based at least in part on a comparison of the load measurement and an aggregate of the first average measurement and the second average measurement.

Abstract: A method of wirelessly charging batteries of devices includes detecting at least two devices being simultaneously present on a charging mat. It is determined, for each of the at least two devices, whether the device is compatible with a wireless charging standard. It is determined, for each of the two devices, whether the device is enabled for a near field communication. Charging of the devices is prevented if at least one of the devices is enabled for a near field communication but not compatible with the wireless charging standard.

Abstract: Embodiments of a mobile device transmitter and methods for transmitting signals in different signal dimensions are generally disclosed herein. The mobile device transmitter comprises a mapper to map a block of two or more input modulation symbols to different signal dimensions comprising two or more spatial dimensions, and linear transform circuitry to perform a linear transform on the block of mapped input modulation symbols to generate a block of precoded complex-valued output symbols such that each output symbol carries some information of more than one input modulation symbol. The mobile device also comprises transmitter circuitry to generate time-domain signals from the blocks of precoded complex-valued output symbols for each of the spatial dimensions for transmission using the two or more antennas. The precoded complex-valued output symbols are mapped to different signal dimensions comprising at least different frequency dimensions prior to transmission.
