A system for wireless power transfer includes a wireless transmission system and a wireless receiver system. The wireless transmission system is operatively associated with a mouse pad includes a transmission antenna configured to transmit one or both of wireless power signals and wireless data signals within a large charge area, the large charge area having a length of in a range of 50 millimeters (mm) to 300 mm and a width in a range of 150 to 500 mm. The wireless receiver system is configured to power a load of a computer mouse and includes a receiver antenna, the receiver antenna including a plurality of receiver coils, each of the plurality of receiver coils configured to receive one or both of the wireless power signals and the wireless data signals within the large charge area.

Wireless power transfer from mouse pad to mouse

A wireless transmission system includes a transmitter antenna configured to transmit AC wireless signals to the at least one antenna, the AC wireless signals including wireless power signals and wireless data signals, the transmitter antenna including a source coil and an internal repeater coil. The system further includes at least one sensor configured to detect electrical information associated with the electrical characteristics of the AC wireless signals at one of the source coil or the internal repeater coil. A demodulation circuit is configured to receive the electrical information from the at least one sensor at the internal repeater coil, detect a change in the electrical information, (iii) determine if the change in the electrical information meets or exceeds one of a rise threshold or a fall threshold, if the change exceeds one of the rise threshold or the fall threshold, generate an alert, and output a plurality of data alerts.

Communications demodulation in wireless power transmission system having an internal repeater

A wireless receiver and transmission systems include a receiver antenna, a sensor, a demodulation circuit, and a controller. The sensor is configured to detect electrical information superimposed on an AC wireless signal. The demodulation circuit is configured to receive the electrical information from the at least one sensor, apply automatic bias control and gain control to generate modified electrical information, detect a change in the modified electrical information and determine if the change in the modified electrical information meets or exceeds one of a rise threshold or a fall threshold. If the change exceeds one of the rise threshold or the fall threshold, an alert is generated. Alerts are decoded into the electrical information.

Automatic gain control for communications demodulation in wireless power transfer systems

A wireless power transmission system includes a transmission antenna that has a source antenna coil and an internal repeater coil. The system further includes two demodulation circuits, for demodulating incoming communications from a power receiver. One demodulation circuit receives sensed signals at the source coil and the other receives sensed signals at the internal repeater coil. The pair of sensed signals are then summed at a summing amplifier to generate a communications signal for input to a controller of the wireless power transmission system.
