... 1292639 Pulse radar TELEFONAKTIEBOLAGET L M ERICSSON 17 Dec 1969 [20 Dec 1968] 61569/69 Heading H4D [Also in Division G4] An arrangement is such that during a signal at a first inlet a signal at a second inlet produces a signal at an outlet and the arrangement is locked against further response to subsequent signals at the second inlet during the signal at the first inlet wherein a register is provided to store the time of occurrence of said signal at the outlet. Video pulses from a radar receiver are fed to an AND gate A on input I 2 ; if a signal is present on I 1 and the output of bi-stable C is in its normal ONE state, the video pulse is passed to a pulse generator B which produces a pulse at its output. This pulse is fed back to C which then changes its output to the ZERO state, thereby closing gate A to any further video pulses. When the signal at I 1 is removed, inverter H causes the bi-stable output to return to its ONE state. A time counter E having p digits comprising bi-stable ...

At the start of each emitted pulse, an up counter 2 is re-set to zero and begins counting pulses from clock 3 which also supplies pulses, via gate 5, to a down counter 4. The counter 4 is reset to full by OR gate 14, i.e., either at the start of each emitted pulse or by a signal from device 9. Every time a reflection occurs, e.g. from 21, it is received at 6 and a signal is passed, via amplifier 7 and threshold detector 8 to device 9 which causes the OR gate to reset counter 4 to full. Several such reflections may be received from discontinuities. When counter 2 is filled, gate 5 is closed and both counters stop. The count number in counter 4 is then a direct measure of the target range as the ...

Whenever a pulse is emitted counter 2 is reset to zero and a count is initiated, the counter being driven by pulse generator 1. A reflection from 5 is received at 6 and the resultant signal is passed via amplifier 7 and threshold detector 8 to gate 9, transferring the count to store 10. If another reflection is received, the corresponding count in 2 is again passed to store 10, updating the stored count. This may occur several times. The last reflection will always be from the target so that the corresponding count will represent the desired range. When counter 2 fills a pulse via line 16 closes gate 15 stopping the counter and via link 17 opens gate 11. The count in store 10 from the last target reflection is therefore transferred to store 12, and via decoder 13 to display 14.

Precision short-range pulse-echo systems with automatic pulse detectors

An equivalent time pulse-echo radar or other pulse-echo system employs a transmit reference sampler collocated with the transmitter to provide a transmit reference pulse, which initiates a pulse width modulated (PWM) pulse. A receive sampler connected to a receive antenna provides an echo-detection pulse that terminates the PWM pulse, such that the width of the PWM pulse indicates target range. The transmit reference sampler and the receive sampler are driven from a common clock such that transmit-receive timing offset drift precisely cancels on a picosecond scale, thereby enabling sub-mm range accuracy with common, low-cost circuit elements. The radar further includes automatically referenced pulse detectors that are responsive to either the magnitude or the phase of the sampler outputs. The radar can be used for precision tank level measurements, robotics, or automotive ranging applications.

Gate transition counter

A gate transition counter. A ring oscillator provides a plurality outputs, each delayed from the adjacent output by a gate delay. The outputs of the ring oscillator are captured by an array of latches upon receipt of a halt signal. The last latch drives a ripple counter. The preferred implementation uses five inverters in the ring oscillator so that each complete cycle of the ring oscillator represents ten gate delays. A ripple counter counts the number of gate delays by ten. The latch outputs and the ripple counter outputs can be converted to a binary representation of the number of gate delays to provide a count with the smallest time increment that can be produced by the circuit.

Random phase modulating time base and method to improve measurement averaging counter resolution

A time base and method to provide resolution improvement for measurement averaging counters when measuring an applied signal comprising time intervals or pulsed frequencies repetitively occurring at rates synchronous to a counter''s clock frequency.

System for pulse time measurement

Method for timing pulses

A method for determining the total time of flight distance of a light pulse from a generator on a moving airborne platform (1) to a target (6) at or near ground or sea level involves triggering a pulse of primary light radiation from the generator (2) towards a surface (6) at or near ground or sea level. The beam is sufficiently intense and of such spectral composition that the beam causes the surface to absorb light radiation. The secondary light backscatter or the reflected primary radiation backscatter is detected and the outgoing primary light radiation and the returning secondary radiation or the reflected primary radiation are used to operate triggers (25,28) on the start and stop inputs of a timer (21) to determine the time of flight of the light pulse from the airborne platform to the target and back again. The total time of flight distances are used to determine the timing of the opening of the shutter or the optical detector gating of the subsequent pulse before the return of that pulse of induced secondary radiation or reflected primary radiation, and, thus, to circumvent the minimum propagation delay in the electronic circuitry.

In particular embodiments, the reflective surface of the device is positioned to receive return laser pulses and is configured to reflect the return laser pulses from the target to a focal point. In various embodiments, the receiver is located at the focal point and is configured to detect the reflected laser pulses to generate a signal used to determine the target's range or velocity.

A system for carrying out the method is characterized by the fact that, instead of totalizing counter modules, successive storage locations in a serial memory device are sequentially indexed under clock-pulse control and, depending upon the time at which a target-reflected pulse is detected, a logic signal is supplied for storage at the instantaneously receptive location within the memory device. Signal-evaluation apparatus including a microprocessor is connected to the memory device to evaluate range from the memory location at which the logic signal is found.

Process and device for the direct measurement of characteristic time constants of rising or falling curves as a function of time,with particular reference to the direct measurement of nuclear magnetic relaxation times

THE TIME CONSTANT OF A PORTION RISING OR FALLING OF AN ELECTRICAL SIGNAL WAVEFORM (ESPECIALLY REPRESENTATIVE OF RELATION PHENOMENA IN NUCLEAR SPRECTROGRAPHY) IS DETERMINED. TO ASCERTAIN THE TIME CONSTANT, THE COUNT OF A NUMBER OF TIME MARKER PULSES IS BEGUN AT A FIRST PREDETERMINED LEVEL OF THE WAVEFORM AND ENDED AT A SECOND PREDETERMINED LEVEL. THE NUMBER OF TIME MARKER PULSES COUNTED IS INDICATIVE OF THE TIME CONSTANT OF THAT PORTION OF THE WAVEFORM WHOSE SIGNAL LEVEL VARIED BETWEEN AND CROSSED THE TWO PREDETERMINED LEVELS.

Electrical timing apparatus with interruptible time presentation

Electronic timing apparatus which, upon being started, maintains and normally presents for observation a running indication of the elapsed time of an event. The apparatus includes circuitry which may be triggered in response to some selected occurrence during the event to produce a short term interruption in the running time presentation, whereby the particular time presentation marking the occurrence is sustained for observation. After such an interruption, the time presentation automatically updates and continues to run.
