Abstract:
A wireless power transmitting device transmits wireless power signals to a wireless power receiving device using output circuitry that includes an array of wireless power transmitting coils that form a wireless charging surface. During wireless power transmission operations, wireless power signals are transmitted from the array of coils to a wireless power receiving device on the charging surface. Inductance measurement circuitry such as impulse response measurement circuitry and other measurement circuitry is coupled to the output circuitry. Control circuitry in the wireless power transmitting device analyzes signals from the measurement circuitry to produce two-dimensional signal profiles across the wireless charging surface and to compare patterns in these signal profiles to predetermined signal patterns associated with the presence of known power receiving equipment on the wireless charging surface. Based on the analysis, charging parameters may be adjusted or other actions taken.

Claim (Index 19):
A wireless power transmitting device with a charging surface configured to receive a wireless power receiving device that has a wireless power receiving coil, the wireless power transmitting device comprising:\n an array of coils; output circuitry coupled to the array of coils and configured to transmit wireless power signals to the wireless power receiving device with at least a selected one of the coils; oscillator circuitry that supplies the output circuitry with an oscillator output signal; signal measurement circuitry coupled to the output circuitry that is configured to make measurements on the output circuitry while the oscillator circuitry supplies the output circuitry with the oscillator output signal; impulse response measurement circuitry coupled to the output circuitry; and control circuitry configured to:\n gather first signal measurements from the signal measurement circuitry for at least some of the coils in the array when the oscillator output signal has a first frequency; \n gather second signal measurements from the signal measurement circuitry for at least some of the coils in the array when the oscillator output signal has a second frequency; \n gather coil inductance measurements for at least some of the coils in the array with the impulse response measurement circuitry; and \n analyze patterns in the first signal measurements, second signal measurements, and coil inductance measurements to determine whether to take an action selected from the group consisting of: initiating wireless communications with the wireless power receiving device, issuing an alert, and transmitting the wireless power signals.
