摘要： A method for measuring time includes setting a clock mask by a starting signal and an ending signal generated upon commencement of measurement and termination of measurement, respectively; obtaining a cycle number of a reference signal under the clock mask to calculate a preliminary time; correcting the preliminary time according to a plurality of phase shift signals generated based on the reference signal; and minimizing an error of the preliminary time by increasing the quantity of the phase shift signals. The method enhances the accuracy of the measured time, speeds up time measurement, and reduces the required circuit areas. A system for measuring time is further introduced for use with the method.

摘要： Die Erfindung betrifft eine Vorrichtung zur optoelektronischen berührungslosen Distanzmessung nach dem Laufzeitprinzip mit einer Sensoreinheit mit mindestens einer Lichtquelle zum Aussenden von Lichtpulsen, mit einem Detektor zum Nachweis von Lichtpulsen, mit einer Einrichtung zum Aufteilen der Lichtpulse in jeweils einen Messpuls und einen Referenzpuls, mit einer Messoptik zum Leiten der Messpulse auf ein Objekt, dessen Entfernung zur Sensoreinheit gemessen werden soll, und zum Leiten von von dem Objekt reflektierten Messpulsen als Echopulse auf den Detektor, und mit einer Referenzoptik zum Leiten der Referenzpulse in Richtung des Detektors, wobei die Entfernung des Objekts von der Sensoreinheit bestimmbar ist aus einer zeitdifferenz zwischen einem Startsignal und einem aus einem Echopuls abgeleiteten Echosignal. Die Vorrichtung ist dadurch gekennzeichnet, dass ein optischer Weg der Referenzpulse zum Detektor um mindestens eine Offsetstrecke kürzer oder länger ist als ein optischer Weg der Messpulse zum Detektor, dass der Detektor zum abwechselnden quantitativen Nachweis sowohl der Echopulse als auch der Referenzpulse dient, dass im Strahlengang der Echopulse ein steuerbarer Pulsabschwächer angeordnet ist zum gezielten Abschwächen der Echopulse, so dass diese mit den Referenzpulsen größenmäßig vergleichbar sind. Die Erfindung bezieht sich außerdem auf ein Verfahren zur optoelektronischen berührungslosen Distanzmessung.

摘要： An analog to digital converter comprises a PWM circuit (10) responsive to an analog parameter of an analog signal. The PWM circuit generates a PWM pulse having a PWM duty cycle proportional to the analog parameter, and a counter (18) generates a plurality of counter pulses during the PWM duty cycle. The subcycle pulse generator (12) generates a series of subcycle pulses during each of said counter pulses, and a latch circuit (22) latches the state of the subcycle pulse generator at a predetermined time relative to the termination of the PWM pulse. A logic circuit (24) then counts the number of counter pulses generated during the PWM pulse to determine an MSB number, and counts the state of the subcycle pulses in the latch circuit to determine an LSB number. Finally, an adder circuit (26) adds the MSB number and the LSB number to provide a digital number representative of the analog parameter.

摘要： A timing circuit for measuring time of arrival of an asynchronous event is disclosed. The timing circuit includes a counter, a register, a gray code-to-binary converter, and a cascade circuit. In response to a time of arrival of a trigger signal that denotes an occurrence of an asynchronous event, the counter generates a set of high-order binary bits and the register generates a set of gray code bits. The gray code-to-binary converter then converts the set of gray code bits to a set of low-order binary bits. Finally, the cascade circuit concatenates the high-order binary bits and the low-order binary bits to form the time of arrival of the asynchronous event.

摘要： In a time measuring system having a high-speed counter section (1) for counting up a counter value in response to a clock signal between supplies of a measurement start signal and a measurement stop signal to produce a counter output signal representative of the counter value, a signal producing section (4) is supplied with a measurement able/disable switching signal and with an original stop signal and produces the measurement start signal and the measurement stop signal. An adding section (2) executes an adding operation as regards the counter value by the use of the clock signal and the counter output signal to produce a sum total of the counter value. Responsive to the sum total, a data producing section (3) produces a resolution datum by the use of the counter output signal. In order to produce the measurement start signal and the measurement stop signal, the signal producing section uses the resolution datum, the sum total, and the clock signal. The measurement start signal and the measurement stop signal are supplied from the signal producing section to the high-speed counter.

摘要： Apparatus and method for measuring a time interval between occurrences of first (A) and second (B) pulses with very high resolution operate to generate a difference pulse (12) representing the difference between the two received pulses, stretch the difference (14) in accordance with a predetermined stretch ratio, produce a compared output pulse (16) that corresponds to the stretched signal, generate a pulse sequence (18) with a first edge that corresponds to the first pulse, a second edge that corresponds to the second pulse, and another edge that corresponds to the compared output pulse, convert times of occurrences of the edges to respective time values (20), derive the time interval between the received pulses from the time values and the stretch ratio, and calibrate the stretch ratio from the time values.
