    • Embodiments of the present invention provide a passive radio frequency identification (RFID) moisture sensor. This moisture sensor includes one or more antenna structures having a tail. The tail is operable to transport a disturbance such as, but not limited to fluid or moisture from a monitored location wherein the antenna has an impedance and varies with proximity to the disturbance. An integrated circuit couples to the antenna structure. This IC includes a power harvesting module operable to energize the integrated circuit, an impedance-matching engine coupled to the antenna, a memory module, and a wireless communication module. The impedance-matching engine may vary a reactive component to reduce a mismatch between the antenna impedance and the IC and produce an impedance value (sensor code) representative of the reactive component impedance. The memory module stores the impedance value (sensor code) until the wireless communication module communicates with an RFID reader and sends the impedance value/sensor code to the RFID reader. The RFID reader may then determine an environmental condition such as the presence of moisture or fluids at the tail of the RFID sensor. This sensor may deploy several antenna and/or tails sensitive to unique disturbances. These tails may be used to monitor different locations as well as different types of fluids. In one particular embodiment, the disturbance is a fluid or moisture within the gutter of a vehicle body.
    • 本发明的实施例提供一种无源射频识别(RFID)水分传感器。 该湿度传感器包括具有尾部的一个或多个天线结构。 尾部可操作地传输干扰,例如但不限于来自监测位置的流体或湿气,其中天线具有阻抗并随着扰动的接近而变化。 集成电路耦合到天线结构。 该IC包括可操作以对集成电路通电的功率收集模块,耦合到天线的阻抗匹配引擎,存储器模块和无线通信模块。 阻抗匹配引擎可以改变电抗分量以减少天线阻抗和IC之间的失配,并产生代表无功分量阻抗的阻抗值(传感器代码)。 存储器模块存储阻抗值(传感器代码),直到无线通信模块与RFID读取器通信,并将阻抗值/传感器代码发送到RFID读取器。 然后,RFID读取器可以确定环境条件,例如在RFID传感器的尾部存在湿气或流体。 该传感器可以部署几个对独特干扰敏感的天线和/或尾部。 这些尾巴可用于监测不同位置以及不同类型的流体。 在一个具体实施例中,扰动是车体的沟槽内的流体或水分。

    • A mount for the improved engagement of a tremolo arm with a pivoting bridge of a stringed instrument is provided. The mount features a body having a first side adapted for an engagement with a surface of the bridge. The arm is engageable to conventional bridges or may be employed with an arm mount having a centered attachment point and can include a biasing washer to maintain a position of the tremolo arm relative to the mount. A tremolo arm mount is provided at a central portion of the body relative to the width of a pathway followed by the strings projecting from the bridge toward the neck of the stringed instrument.
