A projection display system. The projection system includes a light source, illumination optics that are capable of splitting the light from the source into individual color bands, and folding mirrors. The folding mirrors operate to direct the color bands to a reflective element that has a contoured surface. The contoured surface of the reflective element causes the light to form into scanning rasters that are recombined and sent to a spatial light modulator. The spatial light modulator is typically made up of a panel of individually addressable elements. If the spatial light modulator requires polarized light, a polarizing beam splitter and quarter-wave plate are included as part of the illumination optics.

A LED lamp includes an optically transmissive enclosure and a base connected to the enclosure. LEDs are mounted on a ribbon for emitting light when energized though an electrical path from the base.

A method of creating a super-resolved color image from multiple lower-resolution color images is provided by combining a data fidelity penalty term, a spatial luminance penalty term, a spatial chrominance penalty term, and an inter-color dependencies penalty term to create an overall cost function. The data fidelity penalty term is an L1 norm penalty term to enforce similarities between raw data and a high-resolution image estimate, the spatial luminance penalty term is to encourage sharp edges in a luminance component to the high-resolution image, the spatial chrominance penalty term is to encourage smoothness in a chrominance component of the high-resolution image, and the inter-color dependencies penalty term is to encourage homogeneity of an edge location and orientation in different color bands. A steepest descent optimization is applied to the overall cost function for minimization by applying a derivative to each color band while the other color bands constant.

Systems and methods are provided for generating customized labels having electronic circuitry such as RFID circuitry. A printing system generates the label by selectively transfer printing elements (e.g., electronic circuitry, physical components, etc.) and donor layers (e.g., conductive materials, non-conductive materials, etc.) from a ribbon to a receiver (e.g., an item that receives the indicia). In addition, the printing system can program and test the label or indicia thereof, thereby providing the ability to customize each label according to predetermined criteria and to ensure that each label functions properly.
