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 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： Apparatus for producing an output signal responsive to a sensor signal having a unit for setting desired hysteresis values and desired reference values of the sensor signal, aunit for detecting whether the sensor signal has a positive or negative slope with respect to time, a unit for triggering one logical signal when the sensor signal has a positive slope and also exceeds one reference value minus a first hysteresis value, and a unit for triggering another logical signal when the sensor signal has a negative slope and also falls below the sum of a second reference value and a second hysteresis value. The apparatus and method may have more than two reference values and/or more than two hysteresis values simultaneously. The apparatus may be implemented by an embedded microcomputer of conventional type, programmed to perform the signal-processing disclosed. The steps of the process and initial values of the reference values and hysteresis values may be stored in a read-only memory. The method for controlling an output signal responsive to a sensor signal includes steps of setting first and second hysteresis values, setting first and second reference values of the sensor signal, detecting whether the sensor signal has a positive or negative slope with respect to time, triggering a first logical signal when the sensor signal has a positive slope and also exceeds the first reference value minus the first hysteresis value, and triggering a second logical signal when the sensor signal has a negative slope and also falls below the sum of the second reference value and the second hysteresis value. Both reference values and hysteresis values are preferably made programmable by a user. When more than two reference values and/or more than two hysteresis values are used simultaneously, each of those values is programmable.

摘要： A method of controlling a brightness level of an LED by supplying power to an LED in series with a field effect transistor and a resistor. A first voltage is supplied from a digital potentiometer to an operational amplifier. The field effect transistor is activated based on the first voltage from the operational amplifier and a second voltage is varied across the resistor when the field effect transistor is activated. The varying of the second voltage across the resistor causes a change in the brightness level of the LED.

摘要： A multiple-reader system for authentication of articles uses a first reader (400) which employs predetermined modulated illuminating light (20) and a multiplicity of discriminating variables, such as wavelengths (110), amplitudes (120), and time delays (140) relative to the modulated illuminating light (20) to characterize fluorescent light (70) detected from fluorescent indicia on the articles. The fluorescent indicia may also incorporate spatial distributions such as bar codes as discriminating features. Additional readers (410 and 420), which may be readers of fluorescent marks and/or readers of other indicia, are synchronized with the fluorescence reader by timing signals. The discriminating features may be re-programmed by the user of the authentication system. Thus the discriminating features define a user-determined and programmable encryption of the articles' authentic identity. The outputs provided by individual readers (400, 410 and 420) are combined by a computer (85) programmed to produce the authentication result. The fluorescence authentication reader includes integration and synchronization of multiple readers of various types, an improved coaxial optics subsystem (450), and electronic circuitry with improved time-base stability, which cooperate in enhancing signal/noise ratio. The resultant stable triggering of the authentication output of the individual fluorescence reader, combined with time synchronization of the individual fluorescence reader with other readers, provides a reliable integrated multi-reader authentication system.
