Patent number: 11536869Abstract: Systems and methods are described for extended foreign object detection (FOD) signal processing. In aspects, an oscillator reset is implemented in a FOD system to mitigate the effects of intermodulation products. In addition, dynamic frequency allocation is implemented to avoid high noise desensitizing the FOD system. Also, a slow sampling mode is implemented to increase a tolerance to transient foreign objects. Reference tracking and auto-recovery is implemented to bridge power outages. Additionally, the FOD system is configured to support position finding for determining an alignment between the vehicle pad and the base pad using a passive beacon transponder circuit and to perform beacon response cancellation as needed in concurrent FOD operation.Type: GrantFiled: November 30, 2021Date of Patent: December 27, 2022Assignee: WiTricity CorporationInventors: Andreas Daetwyler, Hans Peter Widmer, Lukas Sieber, Martin Ludwig Weber
