Title: (EN) Foreign object detection in wireless energy transfer systems
(ZH) 无线能量传输系统中的外来物检测
Abstract: front page image
(EN) The disclosure features apparatus, methods, and systems for wireless power transfer that include a power source featuring at least one resonator, a power receiver featuring at least one resonator, a first detector featuring one or more loops of conductive material and configured to generate an electrical signal based on a magnetic field between the power source and the power receiver, a second detector featuring conductive material, and control electronics coupled to the first and second detectors, where during operation, the control electronics are configured to measure the electrical signal of the first detector and compare the measured electrical signal of the first detector to baseline electrical information for the first detector to determine information about whether debris is positioned between the power source and the power receiver.
(ZH) 本公开以用于无线功率传输的装置、方法以及系统为特征,其包括以至少一个谐振器为特征的电源、以至少一个谐振器为特征的功率接收机、以导电材料的一个或多个环路为特征并被配置成基于电源与功率接收机之间的磁场来生成电信号的第一检测器、以导电材料为特征的第二检测器、以及被耦合到第一和第二检测器的控制电子装置,其中,在操作期间,控制电子装置被配置成测量第一检测器的电信号并将第一检测器的测量电信号与用于第一检测器的基线电信息相比较以确定关于碎屑是否位于电源与功率接收机之间的信息。
