Abstract:
Receiver signal strength indicator, having an automatic outputting detection circuit, can immediately detect whether its output terminals are connected to a specific apparatus or not. The RSSI comprises an RSSI signal generator, an A/D converter, an automatic outputting detection circuit and at least one output terminal. The automatic outputting detection circuit includes a current detection circuit and an interruption signal generator. When a current passes through the output terminal, the current detection circuit detects the occurrence of the current and generates a push signal. The push signal triggers the interruption signal generator, which in turn generates an interruption signal, and then an RSSI signals are output from the RSSI signal generator due to the interruption signal. The A/D converter converts the RSSI signal into an analog signal. Afterward, the analog signal is output to the exterior through the output terminal.
Abstract:
A tool box includes a main body, a mounting seat pivotally mounted on the main body for mounting a hand tool, a positioning member movably mounted in the main body and releasably locked onto the mounting seat, and at least one tool holder pivotally mounted on the main body for mounting a plurality of tool heads. The main body includes an upper shell and a lower shell. The upper shell has a mounting hole for mounting a control knob. The tool holder has a mounting sleeve for mounting a push button. Thus, the user only needs to press the control knob and the push button to pivot the mounting seat and the tool holder respectively so that the mounting seat and the tool holder can be opened easily and quickly.
