  • Patent number: 10530188
    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.

  • Patent number: 10481189
    Abstract: A wireless remote sensor (110) that is powered by an inductive transmitter (112) and is configured to produce an oscillating wave that varies based on one or more sensed parameters. The oscillating wave is communicated to the inductive transmitter (112) by reflected impedance, where it can be detected to determine the sensed value(s). In another aspect, the present invention provides a wireless remote sensor with a Wheatstone bridge arrangement having an internal resonant circuit to produce an electromagnetic field indicative of the sensed value. In a third aspect, the present invention provides a wireless remote sensor with optical feedback from a reference circuit and a sensor circuit. In a fourth aspect, the present invention provides a wireless remote temperature sensor having coils printed on a material with a high coefficient of thermal expansion so that the size and/or shape of the coils varies as the temperature increases or decreases.

  • Patent number: 10277279
    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: 10225966
    Abstract: A composite metal surface that looks metallic, but permits effective transmission of an electromagnetic field. The composite metal surface can be integrated into various electronic equipment, such as telephones, remote controls, battery doors, keyboards, mice, game controllers, cameras, laptops, inductive power supplies, and essentially any other electronic equipment. The composite metal surface can also be integrated into non-electrically conductive heat sinks, high permeability shielding, and polished metal non-electrically conductive surfaces.

  • Patent number: 10187042
    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.

  • Patent number: 10170935
    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: 10160667
    Abstract: A dielectric barrier discharge lamp assembly for a fluid treatment system. The lamp assembly can include an inductive secondary, first and second electrodes coupled to the inductive secondary, and a lamp including a dielectric barrier interposed between the first and second electrodes. The dielectric barrier can define a discharge chamber including a discharge gas, and one of the first and second electrodes can extend within the discharge chamber. The inductive secondary can be adapted to receive power from a nearby inductive primary to promote a dielectric barrier discharge in the discharge chamber. The resulting dielectric barrier discharge can generate ultraviolet light for the treatment of air or water, or for other applications.

  • Publication number: 20170043189
    Abstract: An acoustic module with a transducer and a solid waveguide. The transducer and waveguide may be curved to focus the acoustic energy along a focal line. The transducer, the top surface of the waveguide and the bottom surface of the waveguide may extend along coaxial curves. The waveguide may include a recess closely receiving the transducer. The waveguide may include an integral skirt that provides a thermal mass. The acoustic module may include a space to accommodate thermal management options. For example, the acoustic module may include a heatsink, an active ventilation system and/or a phase change material. The ultrasound device may include a controller configured to perform a uniformity scan sweep during supply of operating power to the transducer. The uniformity scan sweep can extend through a frequency range that includes the operating point of the acoustic module and does not exceed an acceptable efficiency loss.
