Patent number: 11424647Abstract: A power transmitter (101) for a wireless power transfer system comprises a transmitter coil (103) and a driver (201) generates a drive signal for the transmitter coil (103) employing a repeating time frame with a power transfer time interval and a foreign object detection time interval. A test generator (211) generates a test drive signal for a test coil (209) during the foreign object detection time interval. A foreign object detector (207) performs a foreign object detection test based on a measured parameter for the test drive signal. Prior to entering a power transfer phase, an adapter (213) controls the power transmitter (101) to operate in a foreign object detection initialization mode in which a preferred value of a signal parameter for the test drive signal is determined in response to at least a first message received from the power receiver (105). During the foreign object detection time interval the signal parameter of is set to the preferred value.Type: GrantFiled: May 13, 2021Date of Patent: August 23, 2022Assignee: Koninklijke Philips N.V.Inventors: Andries Van Wageningen, Wilhelmus Gerardus Maria Ettes, Eddy Gerrit Veltman, Antonius Adriaan Maria Staring, Richard Henricus Maria Theelen, Johannes Gerardus Fredericus Kablau

Patent number: 10097040Abstract: A thermal barrier for a wireless power transfer system comprises a first surface area (807) for coupling to a power receiver (111) to be powered by a first electromagnetic signal and a second surface area (805) for coupling to a power transmitter (101) providing a second electromagnetic signal. The thermal barrier (801) further comprises a power repeater (803) with a resonance circuit including an inductor and a capacitor. The power repeater (803) is arranged to generate the first electromagnetic signal by concentrating energy of the second electromagnetic signal towards the first surface area (807).

Patent number: 9444266Abstract: A wireless power transfer system comprises a power transmitter (101) arranged to generate a wireless inductive power transfer signal for powering a power receiver (105). The system comprises a temperature controlled power loop setting an operating temperature for a heating part of a powered device. The system further comprises a receiver (207) for receiving a first temperature for a part of a powered device where the powered device is powered by the power receiver (105). A comparator (209) compares the measured temperature to a first reference temperature associated with the power transmitter (101). In response to the first temperature exceeding the reference temperature, a controller (213) proceeds to restrict the power of the power transfer signal and/or to generate a user alert.Type: GrantFiled: July 11, 2014Date of Patent: September 13, 2016Assignee: Koninklijke Philips N.V.Inventors: Andries Van Wageningen, Antonius Adriaan Maria Staring, Johannes Gerardus Fredericus Kablau, Wilhelmus Gerardus Maria Ettes

Patent number: 7965617Abstract: An optical data storage medium (1) comprising a dye-based recording layer is described. It has substantially parallel tracks for recording user information in a pattern of optically detectable marks, the tracks being provided with a guide groove, the groove being present in a user data area (3) and in an information area (2) and being trackable by a focused radiation beam (7) with the push pull method. The value of the normalized push pull signal (PPN) in the unrecorded information area is PPN-i and the value of PPN in the unrecorded user data area is PPN-u and PPN-i is lower than PPN-u. It is achieved that the information area of such an optical data storage may be read by a legacy optical data drive without causing damage to the drive. Further an apparatus for reading and a corresponding method are described.Type: GrantFiled: April 28, 2006Date of Patent: June 21, 2011Assignee: Koninklijke Philips Electronics N.V.Inventor: Johannes Gerardus Fredericus Kablau
