Abstract: An article and a method for testing the assembly of that article are disclosed. The article includes a plurality of modules, at least two of the modules are capable of being placed in two different positions in the article, each module having a correct position in the article. Each module includes an aperture at a location determined by the desired position for that module in the article. The apertures are placed such that the apertures will be aligned to form a transparent channel when the modules are arranged in a predetermined pattern with respect to one another, but not when arranged in any of the possible incorrect orders. The article can be tested for assembly errors by transmitting a test light signal into the first end and testing for light that traversed all of said first transparent channel.

Abstract: An imaging device and method for producing an infrared (IR) filtered digital image of a scene of interest uses IR image signals derived from light transmitted through infrared pass filters of a color filter array to remove IR light components of color image signals derived from light transmitted through color pass filters of the color filter array. The color and IR image signals are generated using an image sensor that includes an imaging array and the color filter array.

Abstract: A combination of light source types is used to form a dynamically adjusted backlighted display with the particular combination dependant upon the desired light output at a given point in time. In one embodiment, RGB diodes are used for low brightness situations and as the brightness requirement increases white light sources are added. In another embodiment, different light source types are used to produce the different color components and optical feedback is used to control the power levels of the various diode types.

Abstract: In LED back-lighted display systems where the LED driving signals are pulse width modulated, brightness of the LED is determined by the duty cycle (length of the “on” pulse). In such systems, it is possible to, from time to time, skip an LED driving pulse without the human eye detecting the absence of (or change in) color during the “skipped” LED pulse. Using this approach, it is possible to measure the intensity of the light output from each LED of a multi-color LED display. Thus, in an embodiment having three colors, such as red, green and blue, it is possible to determine the light intensity from one of the LEDs (for example, the red LED) by skipping (blanking) the input driving pulses to the green and blue LEDs at a particular point in time. During that point in time the only light coming from the display would come from the unblanked LED which, in this case would be the red LED. It is then possible to measure the intensity of the red LED light using a photosensor without use of a filter. In similar manner, and at some later point in time, the light intensity from each of the other color LEDs can be measured using the same photosensor without using a filter. By spacing the blanking periods properly, the resulting change in color of the display will not be perceived by the human eye.

Abstract: A field-sequential color light system has a light source that includes multiple color light emitting diodes (LEDs) and a spectral feedback control system that is configured to drive the color LEDs, to detect light from the color LEDs, and to adjust color-sequential drive signals in response to the light detection system. Detecting the emitted light and adjusting the color-sequential drive signals in response to the light detection allows luminance and chrominance characteristics of the emitted light from the field-sequential color light system to be maintained at desired levels as the performance of the LEDs change over time.
