Abstract: An estimate of the number of vehicles crossing a loop inductor having one or more interconnected discrete loops of the type found in vehicle detector system installations. A measuring signal follows changes in loop inductance caused by the influence of vehicles crossing the loop inductor. A vehicle count threshold value is computed by observing changes in the measuring signal caused by the first car crossing the loop. Subsequent excursions of the measuring signal between relative minima and relative maxima are tested against the threshold and a vehicle count event is registered when the differences exceed the threshold. After a predetermined count period, the number of vehicle counts is estimated from the total count events by multiplying them by an interpolation factor determined empirically from the type of loop inductor. Apparatus for perfoming the method is combined with a conventional vehicle detector system in a switch selectable apparatus for specifying vehicle detector mode or vehicle count mode.

Variable hysteresis for call/no call signal generation is provided in a single vehicle detector, with the call direction threshold selectable between two values.

Abstract: A microcomputer-based real-time flash x-ray controller, which completely eliminates the "guesswork" in capturing projectiles on radiographs. The microcomputer measures the projectile velocity with high precision, calculates the correct delays in real-time and sends out appropriate triggering pulses to activate the x-ray tubes, arbitrarily arranged along the projectile flight path, to capture the projectile on radiographs at desired locations. The system imposes virtually no restrictions on x-ray tube locations downrange. It is software driven, user friendly and fully programmable for various ballistic range set-ups and it can be easily adapted to synchronize the time-critical controls of other equipment such as high speed cameras, target instrumentations, and the like. The use of a personal computer, centralizes the range operations as equipment control and experiment record-keeping become an integral task.

Abstract: An automatic vehicle detection system within a toll collecting system has a scanning laser unit positioned on one side of a roadway, a vertical photoelectric detector on the opposite side of the roadway and a treadle extending across the roadway. The laser beam scans the height of the detector at regular intervals, and the detector produces a first signal indicative of a vertical dimension of an object (car or truck) intercepting the laser beam. The treadle detects each set of wheels and produces a second signal indicative of a horizontal length of the object. A control circuit uses the first and second signals to generate a count of the number of objects and to categorize each object as one of a plurality of known vehicles.

Abstract: A device for measuring the distance travelled by and the speed of a rail vehicle fitted with wheel-coupled distance-pulse generators is disclosed in which both distance and speed are calculated from the time distance between successive distance pulses, and in which the change in wheel diameter due to wheel wear is already taken into account in the measurement of the time distance between the distance pulses (distance-pulse intervals). To measure the distance-pulse intervals, clock pulses of reduced repetition rate are counted which are obtained by dividing basic clock pulses of high repetition rate in an adjustment divider (T1). The wheel diameter is taken into account by changing the division ratio of the adjustable divider by means of a coding switch (S1).

A retainer prevents road tube separation from the housing. An electrical cable of flat section passes downwardly through the base plate and terminates at a remote tallying component.

Abstract: An improved traffic monitoring system is disclosed in which a microprocessor is connected to an analog to digital converter providing a series of digital samples of the pressure within a road tube for analysis of the signals. If a pulse is detected exceeding a threshold level, corresponding to passage of a tire over the road tube at a relatively high rate, the microprocessor then determines whether pressure in the tube subsequently drops below a repetitively-updated baseline value. If the pulse in the pressure does not exceed a predetermined threshold, the microprocessor determines whether the pressure continues to rise for a stated period of time and to exceed a set minimum value, whereupon the conclusion is reached that a relatively slowly moving tire has passed over the road tube. The microprocessor is disabled from detecting a second tire within varying intervals after detection of a pulse.

Abstract: A Hall effect element, incorporated into an integrated circuit unit with temperature compensation, voltage regulation, and amplification, is mounted on top of a permanent magnet made of ceramic material with the critical Hall axis aligned with the magnet pole axis. To avoid saturating the Hall cell, it is positioned within a pole-to-pole hole in the magnet, which creates a flux null space. The permanent magnet and Hall cell assembly is mounted on the rail a predetermined distance below the top so that the flange of passing wheels occupies the air gap between the magnet and the rail through which the major portion of the magnet flux flows. Reduction of the air gap increases the level of the magnet flux and thus the level of voltage output of the Hall cell. The output of the Hall cell is applied to a Schmitt trigger whose switching level is set by a threshold voltage unit.

Abstract: A speed independent system is used for obtaining a preselected number of samples from an object moving along a fixed path, such as a railroad train passing through a sensing zone along the section of track. The sensing zone is defined by a pair of wheel sensors. Upstream of the sensing zone a third sensor is positioned. The distance between the third sensor and the closer of the pair of sensors comprises a reference distance which is the length of the sensing zone multiplied by a known multiple. The time for the train to pass through the reference distance is obtained and then divided by a divisor comprising the product of the known multiple and the desired number of samples to obtain a single interval. During the time the train passes through the sensing zone consecutive intervals are counted off to obtain the desired number of samples.
