Patent number: 10530188Abstract: 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.Type: GrantFiled: January 17, 2018Date of Patent: January 7, 2020Assignee: Philips IP Ventures B.V.Inventors: David W. Baarman, Colin J. Moore, Joshua B. Taylor, Matthew J. Norconk, Thomas J. Leppien, Scott A. Mollema, Joshua K. Schwannecke, Benjamin C. Moes, A. Esai Umenei, John James Lord, Robert D. Gruich

Patent number: 10187042Abstract: 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.Type: GrantFiled: January 23, 2013Date of Patent: January 22, 2019Assignee: PHILIPS IP VENTURES B.V.Inventors: David W. Baarman, Benjamin C. Moes, Joshua K. Schwannecke, Joshua B. Taylor, Neil W. Kuyvenhoven, Matthew J. Norconk, Colin J. Moore, John James Lord, Kristen J. Blood

Patent number: 9680311Abstract: A wireless power system for wirelessly transferring power to a remote device from a wireless power supply at a range of distances. Various embodiments are contemplated in which reflected impedance from the remote device can be reduced by reducing coupling outside the desired wireless power transfer path, allowing delivery of wireless power over a range of distances. For example, a system incorporating one or more of shielding, spacing, and offsetting may be used to reduce reflected impedance from the remote device. An adapter may also be used to extend the range of wireless power transfer.Type: GrantFiled: March 14, 2013Date of Patent: June 13, 2017Assignee: Access Business Group International LLCInventors: Kristen J. Blood, Joshua B. Taylor, Matthew J. Norconk, Colin J. Moore, Benjamin C. Moes, John James Lord

Patent number: 7622868Abstract: An inductively powered gas discharge lamp including both a power coil and a heating coils associated with each filament. The heating coils enable the filaments to be preheated before the starting voltage is applied through the power coils. The inductive power coils and the inductive heater coils are contained within the lamp envelope, allowing the lamp to be entirely sealed. A method of dimming the lamp also is disclosed. The lamp is dimmed by both decreasing the power applied to the power coils and increasing the power applied to the heating coils so as to prevent the arc from extinguishing under lower voltage conditions.Type: GrantFiled: August 1, 2006Date of Patent: November 24, 2009Assignee: Access Business Group International LLCInventors: David W.
