Title: Trigonometrical survey type range finder and inter-vehicle distance control device
Inventor: KAJIWARA YASUNARI
IPC: G01C3/06
Filed: 1992-12-22
Abstract: PURPOSE:To improve resolution at a long distance so as to obtain a stable measured value with small fluctuation by changing a filter constant in accordance with the measured value of the measured distance. CONSTITUTION:A trigonometrical survey type measuring instrument is used as a distance sensor 30, and a control device 31 executes the filtering processing of the measured value of inter-vehicle distance by changing the filter constant in accordance with the measured value measured by this trigonometrical survey type measuring instrument. That is, at the time of calculating the distance in the control device 31, a result is obtained by putting a filter in the way of software. This secures the high resolution and the stability of the measured value extending over a range from a short distance to a long distance by enlarging the number of the samples of moving average, that is, to enlarge the filter constant as the distance becomes longer by executing the moving average at the time of aruthmetic operation. Thus, a problem that the speed of a vehicle fluctuates always and the vehicle is made unconfortable to ride or the problem that safe travel is endangered because a measure to cope with the vehicle breaking into a queue, etc., is delayed when the speed of the vehicle is controlled by lowering the control gain of the control device can be solved.

Title: Waveform generation device for mr device
Inventor: IMAHORI KIYOSHI
IPC: G01R33/20
Filed: 1989-12-30
Abstract: PURPOSE:To enable the change of amplitude at the arbitrary portion of a waveform by adding information indicative of the update point of an amplitude value, or information assigning specific gain data to the additional data of a waveform memory. CONSTITUTION:Waveform data C and amplitude value update bits A added thereto are stored in a waveform memory 1, and sequentially read out. The waveform data C is sent to an amplitude adjuster 2, while the amplitude value update bits A are sent to a controller 3. This controller 3 accesses a register file 4 for gain data B, depending upon the amplitude value update bits A, and sequentially reads out the gain data B for sending to the amplitude adjuster 2. This adjuster 2, for example, consists of a multiplier, and the multiplying factor or the like thereof is set with the gain data B, thereby changing the amplitude of the waveform data C. When the amplitude value update bits to be added to leading waveform data at a portion desired for the change of waveform amplitude, is set and gain data corresponding to the register file for the gain data B is set at desired amplitude, therefore, the amplitude of the waveform can arbitrarily be changed independently at each portion thereof, according to a real time.
