Title: Measuring apparatus for position of moving body
Inventor: SASAKI RIICHI
IPC: G01S5/16
Filed: 1987-01-19
Abstract: PURPOSE:To make it possible for a moving body to recognize its own position with ease and with high precision, by detecting a lighting signal of a flashlight or the like when the line of collimation of a video camera on the moving body passes each reference point, and by measuring a horizontal angle between the reference points adjacent to each other. CONSTITUTION:This apparatus consists of a measuring element such as a video camera 2 on a moving body 1, a reference point element of a flashlight provided in a place being apart from the moving body 1, and an arithmetic element by means of a computer. This camera 2 outputs a signal which makes vertical sweep to recognize the lighting of the flashlight. Besides, the camera 2 is rotated at high speed by a drive unit 5, maintained to be horizontal generally, and provided with an inclination sensor 6. A rotary encoder 4 fitted to the same rotating shaft 11 receives the signal from the camera 2 and thereby measures an angle of inclination simultaneously with a horizontal angle between flashlights adjacent to each other. Measured values of the measured horizontal angle and a vertical angle are inputted to the computer, and thereby the computation of the position of the moving body 1 and the correction of the angle of inclination are executed.

CONSTITUTION:The potential 27' of a storage electrode 3a is lower than respective heights 26' and 28' of potential barriers of the signal read-out gate region 2a and the control gate region 7a. When light comes incident to the photodiode 1a in this state, the potential of the diode 1a increases to the potential corresponding to the intensity of the incident light. Next, if the respective heights of potential barriers of the regions 2a, 3a, and 7a in case of reading out signal charges accumulated in the photodiode are 26, 27, and 28 by impressing a high level VH on a polycrystalline Si electrode 22, the signal charges accumulated in the photodiode 1a are 23-24. When the amount of charges thereof is that of the signal charges within the maximum amount of charges which can be transferred by the storage region 3a of a signal read-out CCD, the charge exceeding the potential barrier 28 does not exist at all.

Abstract: PURPOSE:To simplify the constitution of the titled circuit and to reduce the number of external terminals and the number of time constant setting parts by providing said circuit with dead band, minimum pulse width and pulse stretch functions. CONSTITUTION:When the terminal voltage of a capacitor 12 exceeds an upper reference voltage VH, the output of a comparator 4 is inverted, an output terminal 46 is shifted to low potential and an output pulse is generated as a pulse stretch output for an error pulse.

The reference voltage is changed in accordance with the output of the comparator 4, hysteresis characteristics are applied to the comparator 4 and a dead band is set up in the comparator by setting up the voltage VL. When the input pulse reaches a prescribed pulse width, the terminal voltage of the capacitor 12 is turned to charging characteristics, the output of the comparator 4 is inverted, a minimum pulse is generated from the terminal 46, and when the minimum pulse exceeds a dead band, its pulse width is turned to the minimum pulse width.
