  • Patent number: 4654663
    Abstract: An angular rate sensor system is disclosed, consisting of a balanced resonant sensor. The sensor consists of a tuning fork of a piezoelectric material, preferably of quartz. The tines of the tuning fork are caused to vibrate electromechanically, for example, by impressing an alternating voltage on a pair of electrodes on each tine. This will cause the tines to vibrate. Any component of angular motion around the axis of the sensor causes a cyclic deflection of the tines at right angles to the normal driven vibration of the tines. If the rotational input to the handle of the sensor is applied through a torsion element, the resulting tine deflection is directed to cyclically rotate the entire sensor along the input/output axis. This deflection can be used for changing the capacitance of a capacitance bridge, or for generating an electric signal, due to the piezoelectric effect resulting from the deflection. Finally, the output signal may consist of a frequency-modulated signal or an optical pick-up may be used.

  • Patent number: 4642636
    Abstract: Numerous signal conditioning circuits on a plurality of printed circuit boards are calibrated remotely by a signal processing unit which sends coded signals to each board, either sequentially or in parallel, to connect either on-board or off-board test signals to one of the conditioning circuits in place of its field generated input. The processing unit utilizes the actual and expected responses of each conditioning circuit to low and high test signals to generate a gain and an offset which are applied to the conditioned field signal to provide a calibrated signal. The time constant for each conditioning circuit is also measured periodically, or upon a selected temperature change, for use in generating a minimum waiting period for obtaining valid data following transfers between the field generated signals and the test signals.

  • Patent number: 4642610
    Abstract: An improved communications device for use by handicapped persons utilizes a list of elements such as the alphabet. The list is sequentially scanned in a forward direction at a speed faster than the response time of the individual. Upon a first operation of a switch, the scan reverses direction and presents the elements at a slower speed. A second switch operation by the user indicates the selection of the desired element. Display and interpretation of the selected element is made in whatever manner desired, and the scanning process is repeated to enable selection of the next element.

  • Patent number: 4641124
    Abstract: A motor vehicle antitheft alarm provides complex sounds, is disabled in normal use of the vehicle, and is resistant to "hotwiring" of the ignition notwithstanding. Unauthorized motion of the vehicle causes a disturbance sensor to activate the alarm circuit. Qualitatively different alarm sounds are provided in response to repeated disturbances as compared with isolated ones. When the ignition is turned on in normal use, a first voltage condition is provided to disable the alarm apparatus. After the ignition is turned off a short time of disabling is provided to permit the user to leave the vehicle before the alarm can be activated. An anti-hotwiring turn-on circuit associated with the ignition switch provides a second voltage condition, or allows same, blocking the first voltage condition from occurring during hotwiring. A voltage-sensitive circuit sets off the alarm when the second voltage condition occurs, deterring hotwiring.

  • Patent number: 4635055
    Abstract: A self contained hot stick mounted radio transmitting module may be temporarily pushed against the power conductor of an electrical transmission line. The module is capable of measuring the temperature of the conductor, and the temperature of the ambient air. It may also measure the electrical potential of the conductor. An alternative module is also capable of measuring current, potential, frequency and power factor (or the Fourier components thereof). The modules transmit these parameters to a local receiver where the data may be displayed. The receiver also may be connected by an appropriate data transmission link, to a power control center.The modules are donut shaped and open like a pair of jaws. One or more spring loaded temperature probes are located such that they may be pushed against a power line when a "donut" is mounted to a hot stick with the jaws open.Power to an open module is supplied by a battery.

  • Patent number: 4631539
    Abstract: A mechanical dial indicating gauge or meter that, without mechanical loading, optoelectronically detects and encodes the pointer position as a digital signal by use of a technique of distributed point position latching. Counter means drives a circuit which cylically sequentially lights LED's along a scale and the count is latched that corresponds to current counter position when a detector on the scale pointer is activated during the sequential lighting. This latched count provides the digital signal of pointer position. This digital signal may then by transmitted to remote indicators, controllers, computers, and/or may be compared to preset values yielding set point outputs. An electrical lead for the detector includes a spiral loosely surrounding the pointer stem.

  • Patent number: 4628316
    Abstract: A circuit and method to compensate for thermal effects on potentionmeter based sensors by presenting two input signals at different times to a comparator; the first utilizing one leg of the potentiometer and the second utilizing both legs. The comparator output will change states after receiving each input signal. The time periods between the receipt of the input signal and the outputs' change of state are stored.The quotient of the time periods cancels out most of the thermal effects on the potentiometer and is still a representative of the original potentiometer signal.

  • Patent number: 4626849
    Abstract: A detection system for use in a movable large haulage vehicle operating in a controlled ground environment to prevent collision with other objects in the environment wherein such objects each have a source for omnidirectionally radiating an optical pulsed signal having a selected pulse repetition rate which identifies the object. The vehicle uses detectors mounted at selected locations on the vehicle, which detectors respond to pulsed signals from objects in close proximity to the vehicle. Appropriate circuitry is used to detect the presence of the objects, the ground direction of the objects relative to the vehicle, and the type of objects so detected.

  • Patent number: 4625206
    Abstract: A system for the detection and recognition of a particular sound pattern including an initial frequency discrimination circuit comprising either band pass filters of pre-selected frequency or IC phase-locked loop tone decoders. A sequence detection circuit is responsive to the frequency discrimination circuit to successively enable paired timers upon detection of audio tones in the proper sequence and frequency. Out-of-sequence tones disable the circuit. A trigger pulse is then sent to a counter chain and successive pulse must be received by the counter chain in a predetermined time period to actuate a traffic signal control relay. The system used for a traffic signal control further includes a direction differentiation circuit to cause red lights in one direction and green lights in another as determined by the direction of the source of the sound pattern.
