The electronic calculator has testing program for receiving the motion signal from the tested mouse, thereby judging whether the tested mouse is qualified or not.

Abstract: The present invention discloses a system for testing illuminating elements and a method for testing illuminating elements, wherein the method includes the following steps. Firstly, an illuminating element and an unilluminated area on a circuit board are covered respectively. A reference voltage is obtained according to a brightness of the unilluminated area and a testing voltage is obtained according to a brightness of the illuminating element being driven. Afterwards, whether the illuminating element passes a testing process or not is judged from the reference voltage and the testing voltage.

Abstract: A keyboard testing method is used for testing an ordinary key and a special key. The keyboard testing method includes the following steps. Firstly, receive a key message outputted from the keyboard. Then, detect the key message and judge whether the key message is a special message. If the key message is the special message, intercept the special message and convert a code of the special message. Then, judge whether the code of the converted special message is one of plural default key codes. If the key message is an ordinary message, process the ordinary message and judge whether a code of the processed ordinary message is one of the default key codes. After all keys of the keyboard have been tested, the keyboard testing method is completed. The use of the keyboard testing method of the present invention is able to test the special key of the keyboard.

Abstract: A keyboard module testing system includes a computer host, a test frame, an encoding program and a main test program. The encoding program and the main test program are both installed in the computer host. The test frame is connected with the keyboard module and the computer host for generating plural key codes. The encoding program is used for assigning plural key codes to respective keys. According to the plural key codes, the main test program can recognize which key is being tested.

Abstract: A circuit board testing system and a circuit board testing system for testing a circuit board of keys. The circuit board testing system includes a computer and a test frame. The circuit board is placed on the test frame. The computer includes a script database with plural pin test scripts, a script generation program and a test program. The test program is used for searching a pin test script corresponding to the circuit board from the script database, and testing the circuit board according to the pin test script. If the pin test script is not searched from the script database by the test program, the script generation program is activated to create the pin test script.

Abstract: An automatic keyboard testing system includes a computer, an automatic testing program and a testing frame. A keyboard circuit board to be tested in placed on the testing frame. The automatic testing program is installed in the computer for generating a testing signal and has a predetermined time period. The testing frame generates a simulating signal according to the testing signal and conducts a key intersection point corresponding to the simulating signal, so that the keyboard circuit board output a key scanning code corresponding to the conducted key intersection point to the computer. The automatic testing program discriminates whether the key scanning code is transmitted to the computer within the predetermined time period.

Abstract: An optical mouse testing device includes a testing frame, a control unit, a transmission unit, a rolling unit and an indicating unit. An optical mouse to be tested is placed on an upper surface of the testing frame. The control unit is used for driving the transmission unit according to the route coordinate data. The transmission unit is used for rendering a rolling motion of a ball of the rolling unit. The optical mouse senses the rolling motion of the ball, thereby providing a route coordinate data to the control unit. The control unit compares the route control signal with the route coordinate data, thereby generating an indicating signal to indicate a testing result.

Abstract: An automatic testing system and method for judging whether a universal serial bus device is configured to a computer are provided. The automatic testing system includes a computer and a testing device for testing the universal serial bus device. By judging whether the universal serial bus device is configured to the computer, the automatic testing system could determine the timing of performing an automatic testing procedure on the universal serial bus device.

Abstract: A keyboard device and a key function identification method are provided. The keyboard device includes a micro-controller, a wire circuit and multiple keys. A key code table has been previously stored in the micro-controller. The multiple keys have different key identification parts. When the key identification parts are electrically connected the wire circuit, different key codes are generated. According to different key codes and the key code table, different key signals are generated.

Abstract: An end-of-fill detection arrangement is provided in a power distribution system to detect when a clutch is fully filled and the pressure therein can be progressively increased to full engagement. The arrangement includes placing a position sensor in a pressure relief valve that is controlling the desired pressure level to respective clutches and directing the sensed position of the valving element therein to an electronic controller. The controller monitors the position of the valving element in the relief valve. Initiation of filling of a clutch results in the valving element moving from a bypassing position towards a flow blocking position. This movement is noted by the controller and when the valving element returns generally to its initial location, the clutch is filled. The controller notes the end-of-fill and provides a command signal to the proportional valve to progressively increase the pressure in the clutch until the clutch is fully engaged.
