Abstract: A battery-powered occupancy sensor for detecting an occupancy condition in a space comprises first and second batteries, an occupancy detector circuit, a controller, and a wireless transmitter for transmitting a first wireless signal in response to the occupancy detector circuit detecting the occupancy condition in the space. The controller and the wireless transmitter are powered by the first battery, while only the occupancy detector circuit is powered by the second battery, such that the occupancy detector circuit is isolated from noise generated by the controller and the wireless transmitter. The occupancy detector circuit draws a current having a magnitude of approximately 5 microamps or less from the second battery. The occupancy sensor transmits a second wireless signal is response to determining that the voltage of one of the batteries has dropped too low.

Abstract: A load control system controls an electrical load provided in a space and comprises a load control device and one or more occupancy sensors. The load control device controls the load in response to the wireless control signals received from the occupancy sensors. Each occupancy sensor transmits an occupied control signal to the load control device in response to detecting an occupancy condition in the space and a vacant control signal to the load control device in response to detecting a vacancy condition. The load control device turns on the load in response to receiving the occupied control signal from at least one of the occupancy sensors, and turns off the load in response to receiving vacant control signals from both of the occupancy sensors. The load control device is operable to determine that no wireless control signals have been received from the occupancy sensors for the length of a predetermined timeout period and to subsequently turn off the load.

Abstract: A system for independent control of electric motors and electric lights includes a plurality of two-wire wallstations coupled in series via power wires between an alternating-current (AC) source and a light/motor control unit. The light/motor control unit is preferably located in the same enclosure as an electric motor and an electric light and has two outputs for independent control of the motor and the light. The light/motor control unit and the wallstations each include a controller and a communication circuit that is coupled to the power wiring via a communication transformer and communicate with each other using a loop current carrier technique. The light/motor control unit and the wallstations utilize pseudo random orthogonal codes and a median filter in the communication process.

Abstract: A fault distance indicator (FDI), locates a fault in a power line by modeling pulses of reflected travelling wave signals which are generated from electrical arcs that occur as a result of the fault. Open loop power distribution circuits are arranged in two halves, each half comprising a circuit length from the overhead feed point to an open point with transformers and cable sections located along the circuit length. An FDI is inserted in each half of the loop. The FDI device monitors the circuit using an antenna which receives radio-frequency signals emitted by line faults and records the signatures of these faults. When the “trouble crew” arrives at the scene the recorded signature is downloaded to a portable PC via a radio, infra-red or other telemetry link. The downloaded data is analyzed first to generate a model of the reflected travelling wave signal and then parameters of the model are adjusted to minimize differences between the model and the actual data. The result is an approximate response characteristic of the faulted power line with arcs generated in the fault condition being modeled as an impulse. Parameters derived from this response characteristic direct the crew to the precise fault location.

Abstract: Location of a fault in electrical conductors from a terminal position which may be remote from the fault using at least a broad band pulse generator to generate a pulse at a terminal position. It also uses a voltage source at the terminal position capable of inducing a change of impedance at the fault and time measuring means also at the terminal position. The method involves generating a first pulse at the terminal position which is propagated down the conductor and reflected back to the terminal position from various impedance discontinuities, including the impedance discontinuity of the fault, if present. The pattern of reflections from points along the conductor up to the fault resulting from the first pulse are recorded. Then sufficient voltage is applied to the cable to induce a change in impedance at the fault. Simultaneously a second pulse similar to the first is generated at the terminal position and reflected back from the various impedance discontinuities, including the modified impedance discontinuity at the fault. The reflections of the first pulse are then substracted from the reflections of the second pulse leaving the pulse reflected from the fault. The location of the fault is then determined from the time taken from initiation to reflection of the pulse to the terminal position.
