    • A power distribution and anti-theft alarm system for monitoring a plurality of electronic equipment utilizes existing front-end noise suppressor capacitors to provide a return path along the power supply lines of an injected RF current back to the system monitoring. Accordingly, removal or cutting of the power supply cords to the various electronic equipment can be monitored to provide a theft deterrent. Corresponding LEDs are utilized to provide status of the various channels coupled to the power distribution and anti-theft alarm system. Accordingly, power on/off, alarm on/off and electronic equipment status is indicated.
    • 用于监测多个电子设备的配电和防盗报警系统利用现有的前端噪声抑制电容器,将注入的RF电流的电源线的返回路径提供回系统监控。 因此,可以监视对各种电子设备的电源线的去除或切割以提供防盗威慑。 相应的LED用于提供耦合到配电和防盗报警系统的各种通道的状态。 因此,指示电源开/关,报警开/关和电子设备状态。

    • The invention is directed to a system for detecting the presence or absence of a blocker to an air code flow. The system comprises an active air code generator, a sensor element through which an air code generated by the active air code generator travels, and an air code detector, which detects the air code, wherein if the detection of air code by the air code detector is interrupted, it signals the presence or absence of a blocker of the air code.
    • 本发明涉及一种用于检测空气代码流的阻塞器的存在或不存在的系统。 该系统包括主动式空气代码发生器,由主动式空气代码发生器产生的空气代码行进的传感器元件和检测空气代码的空气代码检测器,其中如果空气代码检测器检测到空气代码 被中断,它指示空中代码的阻塞者的存在或不存在。
