摘要： A system for controlling LED light fixtures such that in the event of a loss of the lighting control signal the LED light fixtures may be controlled in a proper and predictable manner. The system includes a Digital Power Module (DPM) that receives the lighting control signal and transmits a control signal to a Fixture Control Module (FCM) connected to the LED lights. In the event the lighting control signal is not received by the DPM, it is adapted to send a backup control signal to the FCM to control the LEDs. Additionally, in the event the DPM fails to send a control signal to the FCM, the FCM is adapted to control the LEDs is a predefined manner such that the LEDs are always functional even with a loss of the input control signal.

摘要： A lighting control system that allows for flexible control of low-voltage LED light fixtures connected to an output of a digital power module such that during “normal” operation where the digital power module is receiving electrical power from the building electrical system, the digital power module controls the connected light fixtures according to a first control scheme and in the event of an interruption of building electrical power (“emergency” operation), the system receives backup power and control the connected light fixtures according to a second control scheme.

摘要： A lighting system provides for control of the perceived color of the light emitted by the light fixture. The light fixture has two light sources, a control circuit pulses the two light sources and changes relative duty cycles of the light sources to alter a perceived color output of the lighting fixture, in response to a control signal. Duty cycles of the light sources are a function of the control signal.

摘要： A lighting system has a lighting fixture with a white light source and a color light source, a control circuit pulses the white and color light sources and changes relative duty cycles of the light sources to alter a color output of the lighting fixture, in response to a change in a control signal from a controller. A comparator compares a reference voltage relating to an aggregate current driving the light sources to a signal voltage relating to the periodic signal from a signal generator. The comparator controls a switch that controls one of the light sources. A duty cycle of the color light source can be vary inversely to a duty cycle of the white light source.

摘要： A system for authentication of articles uses a multiplicity of discriminating variables to characterize light detected from the articles after predetermined illumination. Articles are tested which have been marked with substances such as dye or ink that fluoresce in a region of the optical spectrum when illuminated with light in another region of the spectrum, such as the ultraviolet region. The authentication system illuminates the articles with light modulated at a frequency of more than about 50 kHz, and secondary fluorescent light returned from the articles is synchronously detected. A programmable microcomputer digitizes the synchronously detected signal and analyzes it to compare the signal with predetermined standard digital signals. The standard signals incorporate a number of discriminating features, for example the fluorescent light's wavelengths, amplitudes, and time delays relative to the modulated illuminating light. The standard signals may also incorporate spatial distributions such as bar codes as discriminating features. The discriminating features may be re-programmed by the user of the authentication system. Thus the discriminating features define a user-determined encryption of the articles' authentic identity. For applications in which the articles are stationary, the authentication system can include scanning means to scan the articles with modulated light. In other applications, the articles move past the authentication system optics and do not require scanning. In quality control applications, predetermined fluorescent substances are added in small percentages to tag other materials, which may be non-fluorescent, and the authentication system is used to provide statistical information about the presence and quantities of the tagged materials. The authentication system can include readers of visible bar codes, readers of magnetic stripe codes, or other readers of coded indicia, in addition to a reader of indicia made with fluorescent substances. Security documents having multiple fields, with at least one field bearing fluorescent indicia, make use of the authentication system and methods.

摘要： A soft start circuit for hot installation of modules into an active bus. A very low R.sub.ds MOSFET provides bias through its drain to source path from a bus supply. This path is activated by a gate bias network which charges a capacitor from a supply located on the bus. Further control of the module supply is obtained by circuitry which permits addressing of the module to turn it off or on, temperature sensing to provide thermal protection and current sensing to provide short circuit protection.

摘要： An apparatus for controlling access to a time division multiplexed (TDM) bus includes a frame address register having a plurality of storage registers for storing a plurality of frame addresses designated for use in communicating over said TDM bus. A frame address latch stores a current frame address. A frame comparator, coupled to the frame address register and the frame address latch, compares the designated frame addresses with the current frame address and produces a first signal indicative of the storage register containing a frame address matching the current frame address. A time slot register has a plurality of storage registers for storing a time slot number designated for use in communicating over said TDM bus. A time slot generator generates a current time slot number. A time slot comparator, coupled to the time slot register and the time slot generator compares the designated time slot number with the current time slot number and produces a second signal indicative of the storage register containing a slot number matching the current time slot number. A token generator, coupled to the frame comparator and the time slot comparator receives the first and second signals and generates a token work unique to the first and second signals. A data transfer circuit transfers a data word to or from the TDM bus responsive to the token word.
