Abstract: A method and apparatus for regulating a DC power supply, adaptable for use with a motion sensor switch, by limiting the leakage to ground current of the power supply to comply with U.L. Standards while also enabling the DC power supply to provide a stable DC output voltage which is essentially unaffected by changes in magnitude of the AC supply voltage or changes in ambient temperature. The method and apparatus employs first and second transistors, in which the base and collector of the first transistor and the base and collector of the second transistor are coupled to receive a voltage based on the AC supply voltage, and the emitter of both the first and second transistors are coupled to drive an output circuit of the DC power supply. The emitter of the second transistor is also coupled via a first resistor to the base of the first transistor, and the collector of the second transistor is also coupled via a second resistor to the base of the first transistor.

Abstract: An apparatus and method for controlling a motion sensor switch which is adapted to control a lighting circuit in an area monitored by the motion sensor switch. The apparatus and method employs a setting adjustment device, such as a potentiometer, having a setting range which sets the duration of a delay period during which the motion sensor switch delays deactivating the lighting circuit after sensing that the monitored area has become vacant. The setting adjustment device further includes a first setting position, a second setting position, or both. The apparatus and method further employs a bypass controller, such as a comparator circuit or software-implemented comparator, which, when the setting adjustment device is set to the first or second bypass setting position, controls the motion sensor switch to maintain the lighting circuit activated or deactivated, regardless of whether the motion sensor senses motion in the monitored area.

Abstract: A bicolor indicator is provided for a lighting control system which controllably switches one or more lkighting fixtures on or off in accordance with detected motion, ambient light level and a selected time out period. The indicator indicates when the lighting control system is operating in a bypass on or off mode (i.e., overriding controlled switching based on motion detection and ambient light level) or in an automatic time out mode. The indicator also indicates occurrences of motion detection and whether or not the ambient light level is exceeded.

Abstract: A device for controlling a switching relay to deliver power to a load. The switching relay selectively couples a hot leg of a utility power supply to the load. The load is coupled to a neutral wire of the utility power supply. The device includes a sensor for detecting whether an area is occupied. If the sensor indicates that the area is occupied and the load is powered off, the device monitors the line voltage for a zero crossing. Upon detecting a zero crossing, an amount of time to a subsequent zero crossing is measured and stored. Then, the device waits the amount of time between zero crossings, less a delay time for closing the contacts of the relay, and initiates a closing of the contacts of the relay. Similarly, when the sensor detects that the area has not been occupied for a predetermined amount of time and the load is powered on, the line voltage is monitored for a zero crossing and a time to a subsequent zero crossing is measured and stored.

Abstract: An improved fluorescence detection system is provided which utilizes a relatively high powered, relatively high repetition rate light source with high speed detection electronics to increase system sensitivity and accuracy. In the preferred embodiments, a laser diode is the light source. In one embodiment, the position of a time window is varied to compile a decay profile of a fluorophore. In another embodiment, the time to detection of a photon is used to compile the decay profile. In one aspect of this invention, a histogram of the fluorescence decay is generated by determining a preliminary histogram of the shape and multiplying it by the ratio of the total number of events divided by the number of events comprising the preliminary histogram. In another aspect of this invention, the time of detection after excitation of the photon is started from a random time, such as after a preceding event is detected and the data stored.

Abstract: A sensitive and fast low voltage lamp system controller to provide safe operation of "bare wire" systems that are particularly attractive for use in exhibition and tradeshow booth lighting. The high sensitivity is achieved by emphasizing high frequency noise present during shorts and by proportionately limiting the instantaneous current that tracks the line AC voltage waveform; fast response is provided by a power FET coupled to a bridge rectifier in series with the load and both then in series with a protection relay.
