    • A physiology motion sensor 10 employs digital and analog circuit components to improve detection operations. The sensor utilizes a combination of digital and analog components that may be configured to implement radio frequency motion sensing. The circuit components may be configured to improve performance and decrease complexity of the sensor. Example sensors may transmit and receive reflected radio frequency signals to detect physiological characteristics of a living subject in the presence of one or more noise sources with an integrated micro controller and output data concerning detected motion to an integrated user interface (e.g., touch screen display). The sensor may be configured with dynamic range gating to substantially simultaneously detect physiological characteristics from multiple subjects in different ranges during a common sensing session.
    • 生理运动传感器10采用数字和模拟电路组件来改善检测操作。 传感器利用数字和模拟元件的组合,可配置为实现射频运动感应。 电路组件可以被配置成提高性能并降低传感器的复杂度。 示例性传感器可以利用集成微控制器发送和接收反射的射频信号以检测存在一个或多个噪声源的活体的生理特征,并将关于检测到的运动的数据输出到集成用户界面(例如,触摸屏显示器) 。 传感器可以配置有动态范围门控以在常规感测会话期间基本上同时检测来自不同范围内的多个对象的生理特征。
