An exemplary embodiment of a segmented light guide includes a light channeling layer having at least one slit dividing the light channeling layer into a plurality of segments, and at least one LED associated with the light channeling layer. The slit substantially prevents light from migrating in the segmented light guide between adjacent segments that are divided by the slit.

A device and method for producing an enhanced color image of a scene of interest captures a grayscale image of the scene of interest using a flash of infrared light and a color image of the scene of interest without using any flash of infrared light. The grayscale information from the grayscale image and the visible color information from the color image are combined to produce the enhanced color image.

Device and method for producing an enhanced color image using a flash of infrared light

A visible light communications transmitter combines a modulated carrier signal with a pulse from a pulse generator. The carrier signal is modulated according to data read from a buffer during the pulse.

Method and apparatus for communication using pulse-width-modulated visible light

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.

Method for detecting component placement errors in product assembly and assemblies made therewith

A light source having first and second component light sources, a mixing device, and a controller is disclosed. The first component light source generates light having a perceived color that can be varied within a predetermined two-dimensional region of the CIE 1976 color space in response to a set of color control signals. The second component light source generates white light. The mixing device combines light from the first and second component light sources to produce an output light signal having a perceived output color. The controller generates the set of color control signals in response to an input signal from a source external to the light source, the controller maintaining the perceived output color at a point in the CIE 1976 color space determined by the input signal.

Efficient solid state light source for generating light in a limited region of the color space

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.

Imaging device and method for producing an infrared filtered digital image

A system and method for emitting and detecting light uses a light emitting device, e.g., a light emitting diode, to emit light and to detect incident light. As an example, the system and method may be used in a digital camera, a camera phone or an illuminated device, such as a liquid crystal display device.
