Patent number: 10312732Abstract: An inductive power supply system includes a non-contact power supply for energizing a device. The inductive power supply system includes a communication system for enabling communication between a device and the system. The device transmits an identifier to the system. If the device does not have a transmitter, the system attempts to determine the type of device from a characterization of the power consumption by the device. If the device cannot be characterized, the inductive power supply system can be operated manually.Type: GrantFiled: November 30, 2015Date of Patent: June 4, 2019Assignee: PHILIPS IP VENTURES B.V.Inventors: David W. Baarman, John J. Lord, Nathan P. Stien, Wesley J. Bachman

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. Baarman, John James Lord, Nathan P. Stien, Wesley J. Bachman

Publication number: 20090010028Abstract: An inductive power supply includes a transceiver for sending information between the remote device and the inductive power supply. The remote device determines the actual voltage and then sends a command to the inductive power supply to change the operating frequency if the actual voltage is different from the desired voltage. In order to determine the actual voltage, the remote device determines a peak voltage and then applies a correction factor.Type: ApplicationFiled: September 25, 2008Publication date: January 8, 2009Applicant: ACCESS BUSINESS GROUP INTERNATIONAL LLCInventors: David W.
