摘要： A power receiving apparatus that wirelessly receives power from a power transmitting apparatus comprises a first communication unit communicating with the power transmitting apparatus, a second control unit executing detection of another apparatus capable of performing short-range wireless communication and a first control unit controlling whether to execute the detection by the second control unit. The first control unit, in a case where it is determined that the power transmitting apparatus does not have the detection function, controls to execute the detection by the second control unit when a detection status of another apparatus by the second control unit is undetermined, and not to execute the detection by the second control unit when the detection status is determined. The first communication unit transmits, to the power transmitting apparatus, a signal corresponding to a result of the detection by the second control unit.

摘要： Wireless power transfer systems, disclosed, include one or more circuits to facilitate high power transfer at high frequencies. Such wireless power transfer systems include a damping circuit, configured to dampen a wireless power signal such that communications fidelity is upheld at high power. The damping circuit includes at least a damping transistor that is configured to receive, from the transmitter controller, a damping signal for switching the transistor to control damping during transmission of amplitude shift keying (ASK) wireless data signals. Utilizing such systems enables wireless power transfer at high frequency, such as 13.56 MHz, at voltages over 1 Watt, while maintaining fidelity of in-band communications associated with the higher power wireless power signal.

摘要： A system for wireless communications includes an antenna and a controller, the antenna configured to transmit electrical data signals, the electrical data signals including an encoded message signal. The encoded message signal including one or more encoded message words. The controller is configured to encode one or more message words, of a message signal, into one or more encoded message words of the encoded message signal, based on a coding format. The coding format correlates each of a plurality of correlated ratios with one of a plurality of format words. Each of the plurality of correlated ratios is a ratio of a duty cycle of a pulse to a respective period associated with one or both of the duty cycle and the pulse. Each of the one or more encoded message words are encoded as one of the plurality of correlated ratios.

摘要： Described herein are methods of making and using and apparatus for wirelessly communicating data and providing power, particularly from a location exterior to a body and to an implantable device disposed within a body with tissue. The described embodiments provide apparatus and methods for efficiently transfer data and power between an external transceiver and an (implanted) biomedical device. The method is to modulate power carrier, which wirelessly powers the device, using an asynchronous modulation scheme, such as amplitude shift keying (ASK) modulation, with minimal modulation depth in order to not disrupt the power flow. The digital data is encoded in the pulse width, eliminating the need for synchronization to the power carrier signal and further minimizing the power consumption necessary for data transfer. Additionally, a reverse backscatter method for obtaining data from the implant is described that has flexible, low power operation.
