Abstract:
1. A power transmitting apparatus for transferring wireless power to a receiver, comprising: a power source configured to generate a driving signal; a transmit antenna coupled to the power source and configured to receive the driving signal and transfer a first level of power, via a wireless power field, to detect the receiver, and transfer a second level of power greater than the first level of power, via the wireless field, to the receiver based on detecting the receiver utilizing the first level of power the transmit antenna built into a furnishing; a tuning capacitor configured to tune a resonant frequency of the transmit antenna; a detector configured to detect a closed state of the furnishing and generate a detection signal; and a controller, coupled to the detector and the power source, and configured to adjust a power output of the transmit antenna in response to the detection signal.
