Patent number: 11089661Abstract: A defrosting system includes a radio frequency (RF) signal source, at least one electrode proximate to a cavity within which a load to be defrosted is positioned, a transmission path between the RF signal source and the electrode, at least one bus bar in the transmission path that includes multiple ports to which the electrode may be coupled, a repositionable shelf that is attached to the electrode, and multiple support structures disposed at side-walls of the cavity that support the repositionable shelf. Standoff isolators may attach the electrode to the repositionable shelf and may electrically isolate the electrode from the repositionable shelf. The vertical position of the electrode may be changed by moving the repositionable shelf to be supported by different support structures of the multiple support structures while coupling the electrode to a different port of the multiple ports of the bus bar.Type: GrantFiled: December 14, 2018Date of Patent: August 10, 2021Assignee: NXP USA, Inc.Inventors: David Paul Lester, Lionel Mongin

Patent number: 11013075Abstract: An RF system includes an RF signal source and a single-ended or double-ended impedance matching network.

The non-linear devices are insulating below a breakdown voltage and conductive above the breakdown voltage. The system also includes measurement circuitry configured to measure one or more parameters that reflect changes in the impedance of the impedance matching network. A system controller modifies operation of the system when a rate of change of any of the monitored parameter(s) exceeds a predetermined threshold.Type: GrantFiled: December 20, 2018Date of Patent: May 18, 2021Assignee: NXP USA, Inc.Inventors: David Paul Lester, Lionel Mongin

Patent number: 10917948Abstract: A system and method for defrosting or heating are presented. A radio frequency (RF) signal source provides, through a transmission path, an RF signal to an electrode that is proximate to a cavity of a defrosting system. A rate of change of a ratio of a reflected RF power measurement and a forward RF power measurement along the transmission path is determined to have transitioned from a relatively high value to a relatively low value. At a point in time when the determination is made, the RF signal is provided to the electrode for an additional time duration beyond the point in time, and provision of the RF signal to the electrode is ceased when the additional time duration has expired.Type: GrantFiled: November 7, 2017Date of Patent: February 9, 2021Assignee: NXP USA, Inc.Inventors: Lionel Mongin, David Paul Lester, James Eric Scott
