Abstract: A charging pad for transmitting wireless power waves for charging an electronic device is disclosed. The charging pad includes transmitting antenna elements that are configured to be selectively activated to transmit wireless power waves to the electronic device for wireless charging. The charging pad includes a charging surface including a guiding contour that aligns a position of the electronic device on the charging surface such that a transmitting antenna element is within a predetermined distance of the electronic device and has a predetermined coupling efficiency. The charging pad further includes a transmitter controller integrated circuit (IC).

Abstract: An example system charges an electronic device using wirelessly transmitted radio-frequency power (RF) waves. The system includes the electronic device with one or more movable arms. At least one movable arm includes a receiving antenna element. The system further includes a charging pad that includes a housing. The housing includes at least one guiding contour on a surface that is configured for align a position of the electronic device on the surface of the housing. The charging pad further includes transmitting antenna elements that are selectively activated to transmit radio-frequency power waves to the receiving antenna element of the electronic device. The system also includes a transmitter controller integrated circuit (IC) configured to selectively activate a respective transmitting antenna element of the transmitting antenna elements. Activating the respective transmitting antenna element causes transmission of the radio-frequency power waves to the receiving antenna element of the electronic device.

Abstract: Systems and methods for improved Global Positioning System (“GPS”) function employ two multiband, multiport antennas to receive GPS signals. The antennas also serve WiFi frequencies, and the system utilizes the received WiFi signal strength to correct the GPS reception pattern for detuning due to user contact or other factors. The correction is made via selective combination of the GPS signals from the antennas. In addition, a phase shifter in one of the signal paths is used to account for changes in device orientation and to maximize the upper hemisphere component of the GPS reception pattern.
