Title: Object detecting apparatus
Inventor: TAKAGI MAKOTO
IPC: G08G1/16
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To provide an object detecting apparatus which never fails to detect an object even when a level of a receiving signal becomes small, by changing a threshold level to be smaller as an angle defined between an advancing direction and a front/rear direction of one's vehicle is increased, and projecting transmission signals slantwise to an object on a line of one's vehicle. SOLUTION: In an object detecting apparatus M2, a signal is transmitted in an advancing direction of one's vehicle detected by an advancing direction detecting means M1, and a signal reflected by a front object on a line of one's vehicle is received. When the receiving signal exceeds a threshold level, the object is detected. The apparatus M2 has a threshold level changing means M3 for changing the threshold value to be smaller as an angle of the detected advancing direction of one's vehicle to a front/rear direction of the vehicle is increased. Therefore, when the angle between the advancing direction of the vehicle which is the transmitting direction of the signal and the front/rear direction of the vehicle becomes large to decrease the level of the receiving signal, the threshold value is changed and reduced. The apparatus is accordingly prevented from failing to detect the object.

Abstract: PURPOSE:To restrain a variance of a laser output by a method wherein a temperature characteristic of photoelectric conversion efficiency of a photodiode for detecting the laser output is compensated. CONSTITUTION:A voltage in the reverse direction is applied to a photodiode 19 by a reference voltage source 20, and resistances 21 are in series arranged in the photodiode 19 to convert a dark current into a voltage signal. The signal is amplified by an operational amplifier 22 and resistances 23, 24 to output a dark current monitor signal. This signal and a laser beam monitor signal derived from an operational amplifier 11 are so calculated as to compensate a variance of change efficiency of the photodiode by a differential amplifying circuit comprising resistances 25, 26, 27 and an operational amplifier 28. This signal is compared by a set level of a laser output and an operational amplifier 16 to drive a power transistor 18 through a power transistor driving circuit 17 to control an electric discharge current. Thus, the variance of the laser output due to the temperature variance can be restrained.

Abstract: PURPOSE: To compare the signal from the high impedance signal source in high speed, by providing electronic switch between the input terminals of the differential amplifier.  
     CONSTITUTION: The electronic switch 10 is connected between the input terminals of the differential amplifier and turned on or off with the timing signal 11. With ON state, zero input is given to the differential amplifier 1, then the delay in the comparative operation due to input signal source impedance and parasitic capacitance of the signal line is reduced. If the gain of the differential amplifier 1 is sufficient, the moment when the electronic switch 10 is OFF at the next timing, high or low level is outputted to the output terminal 4. If the timing signal 45 is taken much more than the input signal 21, the differential input waveform 47 is obtained. This is sequentially compared to obtain the output 48 and it is picked up as the latch output 49 with the latch circuit 5.
