  • Publication number: 20160294445
    Abstract: A communication system that uses keyed modulation to encode fixed frequency communications on a variable frequency power transmission signal in which a single communication bit is represented by a plurality of modulations. To provide a fixed communication rate, the number of modulations associated with each bit is dynamic varying as a function of the ratio of the communication frequency to the carrier signal frequency. In one embodiment, the present invention provides dynamic phase-shift-keyed modulation in which communications are generated by toggling a load at a rate that is a fraction of the power transfer frequency. In another embodiment, the present invention provides communication by toggling a load in the communication transmitter at a rate that is phase locked and at a harmonic of the power transfer frequency. In yet another embodiment, the present invention provides frequency-shift-keyed modulation, including, for example, modulation at one of two different frequencies.

  • Patent number: 9344155
    Abstract: A system and method for mitigating interference between two or more inductive systems. Interference can be mitigated by, in response to an interference causing event, temporarily adjusting operation of one or more of the inductive sub-systems to reduce interference. A controller can receives communication from multiple inductive systems and instruct the systems to operate so as to reduce interference. The inductive systems can coordinate to operate out of phase with respect to one another to reduce interference. Communication from a data transfer inductive system can be mimicked by another inductive system so that both systems transmit the communication. Interference between multiple inductive systems can be mitigated by specific physical positioning of the transmitters of the inductive sub-systems.

  • Publication number: 20160134134
    Abstract: An inductive power supply that maintains resonance and adjusts duty cycle based on feedback from a secondary circuit. A controller, driver circuit and switching circuit cooperate to generate an AC signal at a selected operating frequency and duty cycle. The AC signal is applied to the tank circuit to create an inductive field for powering the secondary. The secondary communicates feedback about the received power back to the primary controller. The power transfer efficiency may be optimized by maintaining the operating frequency substantially at resonance, and the amount of power transferred may be controlled by adjusting the duty cycle.

  • Patent number: 9209627
    Abstract: A wireless power supply includes a multi-layer shim assembly. Each shim aids in alignment of coils and routing of conductors in a multi-layer coil array. A shield or PCB can be used as part of the multi-layer shim assembly. Wires can be routed through channels to the edge of the shim assembly or wires can protrude through a portion of the multi-layer shim assembly. Traces can be used to route current through the multi-layer shim assembly. Plastic shims can be created by over-molding coils with plastic.

  • Patent number: 9161484
    Abstract: A selectively controllable electromagnetic shield having an electromagnetic shielding material and a mechanism for selectively generating an aperture in the shield. The mechanism for selectively generating an aperture may be a magnetic field source that generates a magnetic field of sufficient strength to substantially saturate all or a portion of the shielding material. For example, a permanent magnet or DC electromagnet may be used to selectively saturate the shield. In its un-saturated state, the magnetic shield has a high permeability and functions as a flux path for the magnetic field. Once saturated, the permeability of the shield is substantially reduced so that the magnetic field lines are no longer drawn into the shield to the same degree. As a result, once saturated, a substantially greater amount of the electromagnetic field may flow through or around the shield in the saturated region.

  • Publication number: 20150207333
    Abstract: A remote device in accordance with the present invention includes an adaptive power receiver that receives wireless power from the wireless power supply by induction. The adaptive power receiver may be switched among two or more modes of operation, including, for example, a high-Q mode and a low-Q mode. By controlling the switching between modes, the amount of energy received by the adaptive receiver may be controlled. This control is a form of adaptive resonance control or Q control.

  • Publication number: 20150035376
    Abstract: A wireless power transfer component with a selectively adjustable resonator circuit having a Q control subcircuit that varies the Q factor of the resonator circuit to control the amount of power relayed by the resonator circuit. The resonator circuit may be in the wireless power supply, the wireless power receiver, an intermediate resonator or any combination thereof. The resonator circuit may be actively configured based on a feedback circuit. The feedback circuit may sense a characteristic in the secondary circuit or elsewhere and actively operate the control subcircuit based on the sensed characteristic. The feedback circuit may cause the Q control subcircuit to change (reduce or increase) the Q factor when the sensed characteristic crosses a threshold value. The Q control subcircuit may include a variable resistor having a value that can be varied to adjust the Q factor of the resonator circuit.

In one embodiment, the present invention provides dynamic phase-shift-keyed modulation in which communications are generated by toggling a load at a rate that is a fraction of the power transfer frequency. In another embodiment, the present invention provides communication by toggling a load in the communication transmitter at a rate that is phase locked and at a harmonic of the power transfer frequency.
