Abstract: A method for laminating a film over a light emitting diode (LED), where the thickness of a portion of the film disposed over the top surface of the LED is reduced by pressing a flattening element against the top surface of the LED. The resulting form of the phosphor encapsulation allows for an improved color homogeneity.

Abstract: A luminaire in which color or brightness differences of light sources are compensated is provided. The luminaire can include several LED packages providing light to a primary optical component, which directs the light out of the luminaire. Because individual LED packages may output light at slightly different colors and/or brightness, the luminaire can include a secondary optical component having different materials that modify the color, brightness, or both of the output light. The secondary optical component can serve as a filter positioned between the LED packages (e.g., between a LED module) and the primary optical component, or between the primary optical component and the user, or above the primary optical component. The secondary optical component can be constructed by providing colorfast inks, phosphors, or quantum dots on a clear substrate or on a surface of the primary optical component. The materials can be disposed in a non-uniform manner.

Abstract: The present invention alters the frequency response of an optoelectronic device to match a driver circuit that drives the optoelectronic device. The optoelectronic device is formed on a first substrate. A matching circuit is also formed on the first substrate and coupled to the optoelectronic device to change its frequency response. The matching circuit provides a precise and repeatable amount of inductance to an optoelectronic device.

Abstract: An imager comprises an image sensor and a controller coupled to the image sensor. The image sensor is configured to obtain an image of a field of view of the image sensor with a configuration pattern placed in the field of view. The controller is configured to determine a location of the configuration pattern within the image, interpret the configuration pattern, and set a parameter of the imager based on the interpretation of the configuration pattern.

Abstract: A method for reading a meter includes (1) capturing a first image of digits displayed by the meter, (2) roughly locating the digits by correlating the entire first image against symbols, (3) precisely locating the digits by correlating the digits against the symbols, which are now rotated, resized, and repositioned to maximize correlation, (4) determining and storing nominal centers of the digits in a nonvolatile memory. The method further includes (5) capturing a second image of the digits, (6) locating regions of interest in the second image according to the nominal centers, (7) determining vertical positions of full digits (or partial digits) in the regions of interest, (8) aligning symbols (or partial symbols) and the full digits (or the partial digits) according to the vertical position, and (9) correlating the symbol and the full digits (or the partial symbols and the partial digits).

Abstract: A monitoring device includes an imager, a processor and transmission media. The imager is used to capture visual information pertaining to a flame produced by an appliance. The processor processes the visual information to produce processed information. The transmission media is used by the processor to forward the processed information to a monitoring system.
