Abstract: An emergency lighting system provides testing and reporting functionality in a rapidly repeatable fashion for environments with numerous emergency lighting units. In one or more embodiments, the emergency lighting system comprises a plurality of emergency lighting units capable of conducting one or more tests and reporting their operating condition as test results. One or more terminals receive and aggregate the test results and present the same to a user. Emergency lighting units having an undesirable operating condition can then be readily identified and addressed.

Abstract: An emergency detection and notification system provides autonomous mapping of locations of a building or other environment through a plurality of emergency notification units. The emergency notification units utilize wireless signals to generate topology information that identifies the location of the emergency notification units, the outermost emergency notification units of which identify the egress locations of a building. Upon detection of a hazard, the emergency detection and notification system determines the location of one or more hazards using the topology information.

Abstract: An ultraviolet sanitization fixture comprising a plurality of emitters that emit UVC radiation to render various pathogens inert. The plurality of emitters may be organized into a number of sets, with each set emitting distinct UVC radiation wavelengths and being independently controlled. One of the sets of emitters may be operated according to various emission thresholds and reset triggers. In this manner, the ultraviolet sanitization fixture efficiently provides germicidal effects while taking health and safety into account.

Abstract: A fully variable controller allows wide range of output voltages and output currents to be programmed therein. In this manner, a power supply including the fully variable controller can power a wide range of electrical loads having distinct voltage and current requirements. The fully variable controller includes a control unit, a voltage regulator and a current regulator configured, respectively, to provide and maintain voltage and current according to an output voltage and output current programmed into the fully variable controller.

Abstract: A variable output module provides accurate full range dimming or adjustment of power output. The variable output module utilizes the characteristics of an AC or other periodic signal rather than its power output to accurately determine the level of dimming a user desires. In this manner, the variable output module provides accurate full range dimming without the need for calibration to specific AC signals. The variable output module can detect the period of an AC signal allowing the driver to be used with various frequencies without the need for calibration. In one or more embodiments, the driver compares the pulse widths of a dimmed AC signal to the period of the AC signal to determine the desired level of dimming.

Abstract: A dimmable LED driver provides accurate full range dimming for LED lighting. The driver utilizes the timing of an AC signal rather than its power output or other characteristics to accurately determine the level of light a user desires. In this manner, the driver provides accurate full range dimming without the need for calibration to specific AC power levels. The driver may detect the period of an AC signal allowing the driver to be used with various frequencies without the need for calibration. In one or more embodiments, the driver compares the pulse widths of a dimmed AC signal to the period of the AC signal to determine the desired light level. The driver may comprise a signal processor and controller in one or more embodiments.
