Filed: 1989-03-15
Abstract: PURPOSE:To improve position recognizing accuracy by providing a plurality of first receivers which receive ultrasonic pulse signals, and providing a direction judging part which judges the phase difference between a plurality of the ultrasonic wave pulse signals from said first receivers. CONSTITUTION:Receivers 26 which are provided at a moving body 21 receive information from a fixed base 25 as the different ultrasonic wave pulse signals. The frequency of the ultrasonic wave and the delay time of the transmitted ultrasonic wave pulse signal are obtained based on the received ultrasonic wave pulse signals. Namely, the received signal is amplified in an amplifier part 27. The signal is made to pass a filter part 28 which distinguishes the frequency of the ultrasonic wave. Then, the signal is inputted into a direction judging part 29, and the frequency is determined. The direction of the moving body 21 (right and left and front and rear) is determined. Meanwhile, the distance between the fixed base 25 and the moving body 21 is judged based on the received signal which is inputted into a delay-time judging part 30 through the filter part 28 from the amplifier part 27. Furthermore, the results of the judgments of the direction and the distance measurement are added into a position recognizing part 31. Thus the moving body 21 can determine its own position.

Filed: 1985-03-28
Abstract: PURPOSE:To enable a user to change freely the array of key tops to obtain a desired keyboard system by distributing the rewritable memories in response to a group of key tops and changing the contents of these memories. CONSTITUTION:When the array of a group 1 of key tops is changed, a stopper 2 is released to set each key top under a loadable/unloadable state. Then these key tops are rearranged into a desired array. A mode set key 31 of a group 3 of control keys is pushed to set a replace mode for generated key code. When the key code is changed, a key top is pushed and the firmware produces a key code corresponding to the pushed control key top. Then a microprocessor rewrites the key code when a code set key 32 is pushed. This procedure is repeated to rearrange the key tops and to rewrite the key codes. Thus a desired keyboard system is obtained.
