Abstract: Systems and methods of branch circuit load estimation are disclosed. A total power usage of a main line of an electrical distribution panel that includes a plurality of branch circuits with at least two of the plurality of branch circuits coupled to the main line can be determined. A first power usage of the main line is determined with a first of the two branch circuits decoupled from the main line, and a first time period that the first branch circuits is coupled with the main line is identified. A kilowatt-hour energy usage value of the first branch circuit is estimated based on the first time period and a differential between the total power usage and the first power usage.

Abstract: A lighting control system for a space equipped with lamps for illuminating the space comprises a power circuit for supplying power to the lamps, a controllable switch in the power circuit for turning the lamps on and off, an occupancy sensor for detecting motion within the space and generating a motion-detected control signal in response to the detection of such motion, and a timer for measuring a time-out interval following the generation of the motion-detected control signal by the occupancy sensor and producing a time-out control signal in response to completion of the measurement of the time-out interval.

Abstract: A lighting control system includes an enhanced occupancy sensor and/or an enhanced power pack, allowing for more sophisticated and/or accurate lighting control and energy management capability. In one example, the occupancy sensor provides additional information, such as information about movement detected in the monitored area, in the form of a signal superimposed on the occupancy signal, and a specialty power pack is configured to detect and respond to the superimposed information signal, thereby providing enhanced functionality to the lighting control system. The superimposed signal conveying the additional information is made high-speed/short-duration such that it is “invisible” to a conventional power pack and the occupancy sensor remains compatible with conventional power packs. The enhanced occupancy sensor may therefore be used seamlessly with both conventional and specialty power packs, and may be implemented as a “drop-in” component for legacy lighting control systems.

Abstract: A lighting control system includes an enhanced occupancy sensor and/or an enhanced power pack, allowing for more sophisticated and/or accurate lighting control and energy management capability. In one example, the power pack and/or occupancy sensor is networkable, providing the capability to link and coordinate multiple power pack/occupancy sensor combinations, thereby providing zone-wide control and energy management features, such as, coordinated lighting of several areas, the ability to force lights on in a life-safety situation, and the ability to control other equipment in a monitored area (e.g., an air conditioning and/or heating system) responsive to detected occupancy in the area. The networkable power pack includes installation and wiring to an occupancy sensor that is substantially identical to a conventional power pack and therefore may be implemented as a “drop-in” component in a legacy lighting control system, without requiring changes to the occupancy sensors or wiring of the system.

Abstract: A lighting control system is provided for a space that is equipped with multiple lamps for illuminating the space and multiple power circuits for supplying power to different groups of the lamps. The control system stores information relating to the past illumination of the lamps in each of the different groups. The system detects conditions or events that indicate that increased illumination of the space by the lamps is needed, and produces a control signal in response to the detection of a condition or event that indicates that increased illumination of the space by the lamps is needed. In response to the control signal, the system supplies power to at least one of the power circuits, which is selected on the basis of the stored information, to turn ON the group of lamps receiving electrical power from that power circuit.

Abstract: A wall switch is provided for an automatic lighting control system for a space equipped with multiple lamps for illuminating the space and multiple power circuits for supplying power to different groups of said lamps. The wall switch includes at least one sensor detecting conditions or events that indicate that increased illumination of the space by the lamps is needed or decreased illumination of the space by the lamps is allowable. Normal control of the electric lighting is thus automatic to a large degree. But, at least two manually operable switches are coupled to the microcontroller to provide the microcontroller with ON and OFF command signals for at least two of the lamp groups powered by different power circuits. A separate status indicator light for each of the switches is controlled by the wall switch and provides an indication of whether the lamp group associated with each manual switch is currently ON or OFF as a safety and economy feature.

Abstract: A programmable control system includes a control module having one or more inputs to which an external sensor device may be connected, and one or more outputs to which an external actuator device capable of manual override and providing a status feedback signal may be connected. One or more signal inputting devices are provided which a human operator can utilize to enter a learn mode. A display can be used to indicate a mode of the control system, and a memory can be used to store the characteristics of an external sensor device connected to an input and an association between inputs and outputs. A controller/processor has both a learn mode and a run mode. The control module may interface with external actuator devices such as circuit breakers located in one or more panels via an intelligent control bus and an address module.

Abstract: A field replaceable wiring adapter for interfacing a remotely operable switching device to a control device. The wiring adapter contains a set of terminals coupled to control wires extending from the switching device, a conversion circuit, and a second set of terminals coupled to the control device. The conversion circuitry converts a bi-directional current flowing from the control device in a single current path into two separate current paths that share a common conductor. The conversion circuitry extends between the first and second sets of terminals. The mounting element is used to mount the adapter to the control device. Since the wiring adapter contains the interface circuitry and necessary terminals, it may be easily installed or replaced in the field, for upgrade or maintenance purposes, with minimal disruption to power distribution services.
