Title: Active distance measuring apparatus
Inventor: TSURU HIROYUKI
IPC: G01B11/00
Filed: 1988-02-08
Abstract: PURPOSE:To obtain a correct distance measurement data, by obtaining a distance measurement data from a difference between a high level signal value and a low level signal value of an alternating received light signal outputted from a light receiver to prevent effect of an offset and a drift on an amplifier. CONSTITUTION:An infrared projector 1 projects a modulation light to an object intended to measure a distance with the flashing thereof controlled by a projection circuit 2, a PSD 3 receives the reflected light thereof to output photocurrents I1 and I2 corresponding to the position of receiving light and a light receiving circuit 4 converts the photocurrents I1 and I2 into voltage signals S1 and S2. Then, a change-over switch 5 selects either of the signals S1 and S2 based on a command from a CPU 6 and both the signals S1 and S2 are amplified with an amplification circuit 7. Here, the gain of the circuit 7 is controlled variably by the CPU 6 corresponding to a difference between a high level signal value and a low level signal value of the signals S1 and S2 and the CPU 6 determines a distance data from a difference between added values of respective high level values and low level values of the alternating signals S1 and S2. This cancels a portion of effect of an offset and a drift on an amplifier as contained in the received light signals thereby achieving a higher distance measuring accuracy.

Filed: 1985-02-18
Abstract: PURPOSE:To improve responsiveness of fuel injection amount control in replacing of component by providing a learning correction coefficient difference arithmetic means for operating the difference of learning correcting coefficients between the previous time and this time and an erasing means for erasing the learning correcting coefficients when the difference is over a predetermined value. CONSTITUTION:A learning correcting coefficient difference arithmetic means H operates the difference of learning correcting coefficients between the previous time and this time. A judging means I judges that the operated coefficient difference is over a predetermined value. When it is judged the difference is over the predetermined value, an erasing means J erases the learning correcting coefficient stored in RAMC. The replacement time of component is judged from the coefficient difference and the learning correcting coefficient stored in RAM is erased and learning control is started from the first. Thus, the regu lar learning value of new component can be approached in a shorter time than usual, and responsiveness of fuel injection amount control can be made well.

IPC: H04L7/10
Filed: 1995-02-17
Abstract: PURPOSE: To attain high speed pull-in by using a narrow band-limit filter at initial pull-in of a CW signal to make a frequency band of a loop filter broad without deteriorating a loop S/N. CONSTITUTION: Switches 6, 7 are controlled by a CW (no modulation) signal detector 13 and select narrow band filters 2, 3 till a PLL completes initial pull-in and a CW signal is detected. Then a switch 16 is controlled by the CW signal detector 13 similarly to the case with the switches 6, 7 to select a loop filter 14 with a broad band satisfying a required pull-in time. When the initial pull-in is finished and the CW signal detector 13 detects the CW signal, the switches 6, 7 selects band-limit filters 4, 5 passing a modulation signal based on a control signal (i) from the CW signal detector 13 and the switch 16 selects a narrow band loop filter 15 to allow the circuit to enter the usual operation. Thus, stable demodulation is attained even under the condition that the input S/N is deteriorated.
