  • Publication number: 20030001577
    Abstract: A system and method are provided for ensuring increased accuracy of individual relays (e.g., within a control system comprising a sensor) to close substantially coincidentally with respect to a current zero-crossing of an incoming power supply waveform. To determine timing of contact operation, a microcontroller operates the contacts in response to one of a series of test pulses, and determines the amount of time required for contact operation. The difference between timing of contact operation and zero-crossing is determined and adjusted to offset errors incurred by microcontroller threshold variations and power supply voltage variations. The calibrated value is then provided to the sensor in order to extend sensor life.

  • Publication number: 20020181175
    Abstract: A ground fault interrupter apparatus is provided that employs a switching device that is operated in two stages. The first stage operates a solenoid in order to close the contacts and preferably provides coupling between the load and the power source. The second stage maintains the coupling, however, drawing less current and power from the internal devices of the apparatus. Accordingly, the fault interrupter meets various standards for the time required to open and close the contacts as well as keeping the dissipated heat from the device within the required range.

  • Publication number: 20020175815
    Abstract: A dual technology motion or occupancy sensor, and a method for using the same, to control a lighting circuit to activate and deactivate lights in a monitored area. The sensor employs an infrared energy sensor, a microwave energy sensor, and a controller. The infrared energy sensor outputs an infrared energy detection signal indicative of detection or non-detection of infrared energy, and the microwave energy sensor outputs a microwave energy detection signal indicative of detection or non-detection of microwave energy. The controller outputs a control signal to control activation and deactivation of the lighting circuit in response to a condition of the infrared energy detection signal and a condition of the microwave energy detection signal.

  • Patent number: 6472853
    Abstract: A method and apparatus for regulating a DC power supply, adaptable for use with a motion sensor switch, by limiting the leakage to ground current of the power supply to comply with U.L. Standards while also enabling the DC power supply to provide a stable DC output voltage which is essentially unaffected by changes in magnitude of the AC supply voltage or changes in ambient temperature. The method and apparatus employs first and second transistors, in which the base and collector of the first transistor and the base and collector of the second transistor are coupled to receive a voltage based on the AC supply voltage, and the emitter of both the first and second transistors are coupled to drive an output circuit of the DC power supply. The emitter of the second transistor is also coupled via a first resistor to the base of the first transistor, and the collector of the second transistor is also coupled via a second resistor to the base of the first transistor.

  • Patent number: 5877499
    Abstract: A composite Fresnel lens useful in an infrared passive detection system includes an array of Fresnel lens segments having a given vertical centerline and a curvature of a given radius. The Fresnel lens segments fall in first and second groups. Each Fresnel lens segment in the first group has a long detection range and a width less than one-third of the diameter of an original whole Fresnel lens from which the segment was taken. Also, each lens segment of the first group has a geometrical center located horizontally from the vertical centerline of the array along the curvature of the array through a circumferential distance less than one-fourth of the radius of curvature of the array. Each Fresnel lens segment in the second group has a short detection range less than the long detection range by a predetermined amount and a width less than one-third of the diameter of an original whole Fresnel lens from which the segment was taken.

    Abstract: A motion detection system housing includes a base having a back portion attachable to a wall, a cover having a front portion for mounting operative components of the detection system, a primary living hinge integrally connecting lower portions of the base and cover to one another such that the cover can undergo pivotal movement toward and away from the base between opened and closed conditions, and a latch releasably securing upper portions of the base and cover to one another. The cover and base have configurations that permit telescoping of the cover at least partially over the base into the closed condition. The latch can secure the cover to the base at different fixed telescoped positions with the front portion of the cover correspondingly disposed at different fixed declination adjustment positions relative to a reference plane.

  • Patent number: 5764146
    Abstract: A multifunction passive infrared occupancy sensor functions as an occupancy sensor for security systems and also as an occupancy sensor for energy management control systems. The occupancy sensor comprises at least one segmented infrared lens array wherein the segments of the infrared lens array establish different optical lobes in the field of view of the occupancy sensor. At least one pyroelectric infrared detector is positioned at or near the focal point of the segmented infrared lens array, for detecting movement of infrared sources within the field of view of the occupancy sensor and producing an output signal representative thereof. A processing means analyzes the output signal of the detector for security detection purposes by detecting changes in the output signal greater than a given security threshold.

  • Patent number: 5561576
    Abstract: A step down transformer power supply with short circuit protection which uses a minimal size transformer, as opposed to an energy limiting transformer. The transformer is mounted directly on a PC board without additional mounting hardware, and has a fuse in its secondary winding, which is required to pass a UL short circuit test, and is normally nonreplaceable. A low cost circuit limits the current output of the transformer such that the fuse is not blown, even under a shorted output condition, which would normally require replacement of the transformer. A rectifier circuit is coupled across the secondary winding of the step down transformer, and is coupled to a first terminal of a three terminal power regulator circuit which supplies a regulated stepped down voltage through a second terminal connected to a load. The third terminal thereof comprises a current/voltage limiting control terminal.

  • Patent number: 5457595
    Abstract: A high-power relay with a low-power operating circuit is usable in combination with a low-current source of DC power. The source has a hot terminal and a common terminal and a bistable relay has an energizing relay winding with one terminal of the winding connected to the common terminal of the supply. First and second semiconductor switches are connected to a second terminal, the switches being alternately operable in response to control signals to respectively set and reset the relay. First and second capacitors are connected to the first and second semiconductor switches, respectively, and first and second charging circuits are connected to the low-current source and to the first and second capacitors, respectively, to charge the capacitors from the source. The switches are connected to selectively discharge the capacitors in opposite directions through the energizing relay winding thereby to SET and RESET the relay in response to control signals. A method of operating the circuit is also disclosed.
