    摘要: A repeater amplifier boosts weak control signals on a PLC network, with noise discrimination and signal firewall protection. The AC supply voltage is filtered by a high frequency blocking filter to block external noise signals. Operating power for network signaling devices and the repeater amplifier is derived from the clean AC supply voltage. Noise discrimination and signal firewall protection are provided by amplifying and repeating only those receiver pulse signals that (a) have an analog amplitude that exceeds a predetermined analog threshold value, (b) occur during intervals that control data signal modulation is being applied to the filtered AC supply voltage and (c) occur at a frequency within a predetermined frequency band centered on the transmitted power line carrier (PLC) modulation frequency.

    摘要: A lighting control and dimming system utilizes a single traveler conductor for transmitting analog data signals corresponding to a particular light intensity level of a dimmer group. A predetermined binary data word is retrieved from the read-only memory of a remote controller, and is transmitted serially in an analog pulse train over the traveler conductor to each dimmer unit. Each dimmer unit includes a microcontroller and read-only memory in which a group of binary numbers are stored. The analog data signal received by each dimmer is converted to binary and is compared bit-by-bit with each binary number stored in the dimmer memory. A serial bit comparator produces an enable signal in response to a bit-by-bit identity match between the converted analogy data signal and the preset binary number stored in the dimmer ROM. All the dimmers are enabled by the transmitted analog data signal, thus producing a predetermined scene at a particular brightness level corresponding with one of the stored binary numbers.

    摘要: A junction box mounted infrared motion detector is set forth. It incorporates push button controls mounted on a box which has a Fresnel lens looking into the immediate vicinity and which encloses an infrared detector to sense an intruder. An ambient light photocell responsive to visible light is also included to enable the device to be switched off in the daytime and on at nighttime. The circuit controls a remotely powered lamp or other alarm device. The electrical current to the lamp is adjustable by means of a slide control.

    摘要: A slide-type switch for controlling electrical output to a light or motor. The switch includes a printed circuit board having a sliding variable resistor mounted thereon. When the variable resistor is adjusted for minimum current flow, the slide on the variable resistor comes into contact with an actuator arm also mounted on the printed circuit board. The actuator arm then becomes detached from a butt contact, breaking the circuit. A novel knob arrangement is also disclosed for use with standard all face plates.

    摘要: A remotely accessible power controller communicates power reduction command signals by power line carrier (PLC) signaling over existing AC power distribution conductors for automatically disconnecting building lighting loads. Turn-off command signals from a local or remote controller automatically disconnect building lighting loads according to a time-of-day schedule to comply with mandated energy consumption codes applicable to the automatic shutoff of electrical lighting. Load shedding (selective turn off and/or dimming) command signals transmitted from public or private utility companies automatically disconnect or reduce building lighting loads in accordance with load curtailment agreements to limit total connected power consumption below an agreed level. The power controller is connected by a minimum amount of retrofit wiring into an existing end-user alternating current power distribution network, for example, a building power distribution network having AC power conductors that service multiple lighting loads interconnected in one or more power phase groups. Each dimming lighting load is equipped with an addressable dimming module for decoding and executing dimming and turn-on and turn-off power reduction commands. Fluorescent lamps are equipped with addressable electronic dimming ballasts.

    摘要: A lighting control and dimming system 10 utilizes a single traveler conductor for transmitting analog data signals corresponding to a particular light intensity level of dimmers DIM 1, DIM 2, DIM 3, DIM 4, . . . , DIM N in a dimmer group. A predetermined binary data word is retrieved from the read-only memory of a controller that may be remote from the dimmers, and is transmitted serially in an analog pulse train over the traveler conductor to each dimmer unit. Remote signaling and selection of a specific scene are performed independently of the phase of the applied AC line voltage by sampling the logic values of logic high to logic low and logic low to logic high transitions of a zero cross signal. Dimmers enabled by the transmitted analog data signal produce a predetermined scene at a particular brightness level corresponding with one of the stored binary numbers.
