摘要： A microprocessor-controlled airfield lighting control and monitoring system having bi-directional communication between the controlling microprocessor and the airfield lights and/or sensors. The system also includes a metal container for the remote control microprocessor and an improved attachment arrangement for the power transistor associated therewith. A DC power supply is connected to the remote controller microprocessor and has an integrated circuit adapted to sense a threshold voltage, which causes the power transistor to short around the associated power source.

摘要： A digital load cell includes a rocker pin, guided beam torsion ring or other counterforce, a circuit board mounted on the counterforce and an enclosure sealing the circuit board and all but the load bearing surfaces of the counterforce. The circuit board includes an A/D converter and a micrcomputer. Digital communication is provided with the circuit board through a connector mounted on the enclosure. Weight data are corrected digitally. The load cell may be calibrated, characterized, controlled and monitored digitally through the connector from a remote location without physically penetrating the enclosure. One or a number of digital load cells may be connected to a computer or controller to form one or more weighing scales.
摘要翻译：数字测力传感器包括摇杆，导向梁扭转环或其他反作用力，安装在反作用力上的电路板和密封电路板以及反作用力的所有承载表面的外壳。电路板包括A / D转换器和微计算机。数字通信通过安装在外壳上的连接器与电路板一起提供。数字校正重量数据。负载传感器可以通过连接器从远程位置进行数字校准，表征，控制和监控，而不会实际穿透外壳。一个或多个数字称重传感器可以连接到计算机或控制器以形成一个或多个称重秤。
