Patent DE-3071392-D1 (DE)
Title: Signal processing system
Inventor: MURPHY EDWARD FRANCIS
IPC: G01B11/10
Filed: 1980-09-04
Granted: 1986-03-13
Abstract: The diameter of an optical fibre (10) being drawn is monitored and controlled by an optical measuring technique. An electrical input signal is generated by a detector (18) from the fringe pattern produced by directing a laser beam (14) onto the fibre (10). The input signal is connected to appropriate terminals of first, second, third and fourth comparators (36, 38, 51, 52). The input singal is delayed 180° by a delay circuit (40) to provide an input signal to the remaining two terminals of the first and second comparators (36, 38) and is delayed 90° by a delay circuit (54) to provide an input signal to the remaining terminals of the third and fourth comparators (51,52). The output pulses from the comparators are shaped by pulse shapers (46, 48, 56, 58), summed by summers (50, 60, 64) and counted by counter (68) to provide a control signal forthe fibre drawing apparatus (16).

IPC: A61C1/00
Filed: 1981-06-12
Granted: 1984-10-25
Abstract: In a dental apparatus, in which a number of instruments (19 to 22) are connected to a common control circuit (23) which is further connected with a common operator unit (17) having a control member, which is planar movable out of a home position, auxiliary functions related to the instrument operation such as control of coolant composition and energization of an air blow may be energized by the means of the common operator unit (17) by actuating the control member thereof with a movement different from the instrument energizing movement. The energizing movement for an auxiliary function may have another direction than the instrument energizing movement, for example perpendicular thereto in the home position of the control member. In an embodiment in which a certain minimum duration is prescribed for the instrument energizing movement an auxiliary function may be carried out by a movement of shorter duration. The two possibilites may be combined so that also in case of a different direction related to the instrument energizing movement a discrimination may be made between actuation of auxiliary functions of a shorter or longer duration for the purpose for example of stepwise conrol of an auxiliary function.

Title: Radar ground speed sensing system
Inventor: HOFFA ROBERT JOHN
IPC: G01S13/60
Filed: 1984-05-03
Granted: 1989-02-23
Abstract: A vehicle carries a radar transmitter (12) and receiver (14) which provides a Doppler signal representing vehicle ground speed. The Doppler signal is processed by a Schmitt trigger (18) and a flip-flop (20) to generate a symmetrical square wave whose instantaneous pulse-width is the reciprocal of the Doppler frequency. A microprocessor is interrupted by edges of the square wave and processes the pulse-width to produce a symmetrical output square wave (23). The processing steps comprise:
 (1) Input pulse widths exceeding a threshold value set by a timer are ignored
 (2) When the input pulse width INVAL is within 121_2% of the output pulse width OUTVAL the latter is updated in accordance with a weighted average, OUTVAL = (15 OUTVAL + INVAL)/16
 (3) When the input pulse width INVAL deviates more than 121_2% from the output pulse width OUTVAL no updating occurs unless this situation has persisted for 8 or more input pulses, whereupon more abrupt updating occurs in accordance with a second weighted average
 OUTVAL = (3 OUTVAL + INVAL)/4
 where INVAL is the average INVAL over 8 input pulses when the second weighted average is first used but is the latest input width when the situation has persisted for more than 8 input pulses.
