Abstract: There is provided a shock generating device for a simulation gun. A hollow rod is inserted into the cylindrical housing. A shaft is installed in the lengthwise direction inside the housing movably and coaxially along with the hollow rod. One end of a spring is inserted into the hollow rod and the other end, supported by a predetermined cap mounted on the housing. A driven gear is integrated with a hollow cam shaft with a spiral inclined portion and mounted on the cap. A key of the shaft prevents the deviation of the driven gear from the shaft and moves the shaft in the length direction along the spiral inclined portion upon rotation of the hollow cam shaft. A driving device is installed at a side of the housing and has a driving gear engaged with the driven gear.

Abstract: There is provided an apparatus for sensing the location of an object on a screen. The object location sensing apparatus includes an input device and a main body. A transmitter is installed in the input device, for detecting a video signal at a position pointed by an optical system on the screen, transmitting the video signal as an infrared signal, and transmitting key data as an RF signal. A receiver is provided to the main body, for receiving the infrared signal and the RF signal from the transmitter and detecting the position pointed by the optical system on the screen by comparing the reception timing of the infrared signal with the output timing of the present video signal output to the screen.

Abstract: Disclosed is a calibration method for compensating an offset occurring when parts in an industrial robot are exchanged with now ones. A signal generation part is attached to a moving part of the robot. While the moving part is moving, a signal detection part detects the movement of the signal generation part with a sensor therein, and calibration data are generated on the basis of the detected signals. Preset calibration data are amended using a difference between the generated calibration data and the preset calibration data, so that the offset is compensated.
