摘要： A system for controlling the intensity of a lamp including a remote sensing device for detecting the presence of an occupant within an area. The device also transmits a signal based on the currently sensed presence of the occupant. After each transmission of an occupancy signal, the device is inhibited from further transmission for a first predetermined period of time to limit power consumption requirements by the battery powered device. The system also includes a light controller responsive to the transmitted occupancy signal for controlling the level of illumination by the lamp. In the absence of a transmitted occupancy signal within a second predetermined period of time, the light controller will instruct the ballast to reduce the level of illumination by the lamp. In the absence of an occupancy signal being transmitted within a third predetermined time period, the light controller will instruct the ballast to turn off the lamp.

摘要： A telephone-based automatic meter reading (AMR) system includes a telemetry device through which a host computer can collect meter readings remotely. The telemetry device has one or more ports to read one or more meters at pre-scheduled time intervals. All data read from the meter(s) is stored in a non-volatile memory in the device, and the collected data is transferred back to the host computer according to a predetermined schedule (with a call back interval that can be hourly, daily, weekly or monthly). An apparatus and method is provided which enables the host computer to initiate a special data stream to invoke a powerless circuit portion of the telemetry device—specifically, a telephone-side portion which is electrically isolated from the meter-side circuitry (such as by an optocoupler). The ringing signal on the phone line powers the circuitry in this telephone-side portion of the device such that no AC connection or separate battery power is required. Once the telemetry device receives the special data stream, it ignores the regular call back schedule and calls back to the host computer immediately when the shared telephone line is available.

摘要： A programmed electronic ballast circuit including a voltage maintenance circuit to ensure that the integrated circuit continues to oscillate and drive the half-bridge inverter until the DC bus voltage falls to a level insufficient to permit the fluorescent bulbs at the output to ignite. Additionally, the voltage maintenance circuit drives the voltage of the integrated circuit down to a level whereby proper resetting of the integrated circuit and proper preheating of the florescent bulb filaments is assured.

摘要： Building lights are master controlled to reduce power consumption under building master control, or in response to electric utility commands to the building computer. Each lighting wall control unit includes a transceiver which can communicate to at least one neighbor transceiver, thereby forming a distributed communication network extending back to the building computer. The transceivers operate asynchronously with low data rate FSK signals, using carrier frequencies between 900 and 950 MHz. Different communications protocols control packet forwarding and acknowledgement so that messages reach their destination but are not forwarded in endless circles, and so that collisions are minimized.

摘要： An electronic ballast for driving a fluorescent lamp includes an electromagnetic interference (EMI) filter and power circuit, a preconditioner coupled to the EMI filter and power circuit and an inverter circuit coupled to the preconditioner for energizing the fluorescent lamp. The preconditioner includes an active power factor controller and a boost circuit which is controlled at least in part by the active power factor controller. The active power factor controller has a reference voltage input to which is applied a reference voltage. At start up, the inverter provides a time varying signal which is rectified. At least a portion of the rectified signal is fed back to the reference voltage input of the active power factor controller to boost the reference voltage to a level above normal so that the active power factor controller will cause greater current to flow through the boost circuit, causing the boost circuit to generate a direct current (DC) rail voltage more rapidly, which rail voltage is provided to the inverter circuit to ignite and operate the fluorescent lamp.
