摘要： Exemplary embodiments are directed to wireless power transfer. Energy from a transmit antenna is coupled to internal signals on a transmitter. An impedance measurement circuit generates an impedance indication signal for indicating an impedance difference between the coupled internal signals by comparing them. A controller samples the impedance indication signal and determines digital signaling values responsive to changes in the impedance indication signal. The impedance measurement circuit measures one or more of magnitude difference of the internal signals, phase difference of the internal signals, and changes in power consumed by an amplifier coupled between the RF signal and the transmit antenna. A transmitter generates the electromagnetic field with a transmit antenna responsive to a Radio Frequency (RF) signal to create a coupling-mode region within a near field of the transmit antenna.

摘要： The amplified RF output signal (515) of a power amplifier (510) is amplitude modulated by modulating the supply voltage/current of the amplifier. A control unit (522) receives data to be transmitted and a feedback signal (505) that corresponds to the sensed supply voltage and/or supply current. In response to these signals, the control unit (522) modulates the supply voltage/current of the power amplifier.

摘要： Apparatus and methods are operable to receive a first and second version of an ordered list having a first and second plurality of ordered entries, wherein each of the plurality of ordered entries has a corresponding order index. Further, the apparatus and methods are operable to compare respective ordered entries from the first and second versions of the ordered list at a respective order index. Also, the apparatus and methods are operable to assign a penalty to each possible current list resulting from reconciling the first version and the second version of the ordered list when the comparing identifies a difference between respective ordered entries at the respective order index. Moreover, the apparatus and methods are operable to generate, based on the comparing, at least a portion of all possible current lists, and select and store one of the possible current lists as the current list based on the penalties.
