Patent number: 11888337Abstract: A system and method of controlling inductive power transfer in an inductive power transfer system and a method for designing an inductive power transfer system with power accounting. The method of controlling inductive power transfer including measuring a characteristic of input power, a characteristic of power in the tank circuit, and receiving information from a secondary device. Estimating power consumption based on the measured characteristic of tank circuit power and received information and comparing the measured characteristic of input power, the information from the secondary device, and the estimated power consumption to determine there is an unacceptable power loss. The method for designing an inductive power transfer system with power accounting including changing the distance between a primary side and a secondary side and changing a load of the secondary side.Type: GrantFiled: December 2, 2020Date of Patent: January 30, 2024Assignee: Philips I.P.

Patent number: 10862335Abstract: A system and method of controlling inductive power transfer in an inductive power transfer system with power accounting. Parasitic metal in proximity to the primary unit can be more accurately detected by accounting for changes in known power losses during operation. The amount of power loss during inductive power supply transfer in an inductive power supply system can vary depending on the alignment of the primary unit and the secondary device. The amount of power loss during inductive power supply transfer can also vary as a function of changes in the operating frequency of the switching circuit in the primary unit or as a function of changes in the secondary device load.Type: GrantFiled: November 14, 2016Date of Patent: December 8, 2020Assignee: Philips I.P.

Patent number: 10277279Abstract: 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.Type: GrantFiled: June 14, 2016Date of Patent: April 30, 2019Assignee: PHILIPS IP VENTURES B.V.Inventors: Matthew J. Norconk, Joshua K. Schwannecke, Colin J. Moore, Joshua B. Taylor, Neil W. Kuyvenhoven, Dale R. Liff, Jason L. Amistadi, Robert D. Gruich, Arthur Kelley, Kenneth C. Armstrong

Patent number: 10250083Abstract: The present invention relates to wireless power supplies adapted to supply power and communicate with one or more remote devices. The systems and methods of the present invention generally relate to a communication timing system that may ensure information being communicated does not overlap with that of another device, preventing data collisions and information from going undetected. With information being communicated in a way that addresses or avoids potential communication issues in multiple device systems, the wireless power supply may control operation to effectively supply wireless power.Type: GrantFiled: March 14, 2013Date of Patent: April 2, 2019Assignee: PHILIPS IP VENTURES B.V.Inventors: Joshua B. Taylor, Matthew J. Norconk, Colin J. Moore, Benjamin C. Moes, Merdad Veiseh, Dale R. Liff, Mark A. Blaha, Jason L. Amistadi
