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.

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.

Mounting structure is provided on the housing for removably mounting the housing to at least one of a sensor array module and a mounting and connection base. A circuit in the housing delivers voltage and current signals received at the first and second connectors to a further connector mounted on the housing. First and second mounting structures are provided for mounting the housing to a surface and for mounting a removable metering module.

Abstract: The present invention provides an electrical power distribution system which contains a primary load-center (100) having a common data bus (124) that is adapted to provide two-way digital communication. A number of circuit breakers (120) are coupled to the common data bus (124). Each circuit breaker (120) has a first contact and second movable contact which is moved between a closed position and an open position by an actuator (216). The circuit breaker contains a microcontroller based control circuit (210), which controls the operation of the actuator (216) according to programmed instructions, which may be stored in a memory (234) contained in the circuit breaker or which are communicated to the circuit breaker over the common data bus (124). A status detection circuit (218) coupled to certain nodes within the circuit breaker provides status information about various contacts and current paths contained in the circuit breaker.
