An emergency lighting device for providing a directional indication on a recipient surface with first and second guidance indication light sources retained relative to a housing to emit beams of light, each with a directional indication, onto a recipient surface. The light sources can be individually operable and can have directional indications, such as arrows, pointing in first and second different directions. An illumination light source without a guidance indication can illuminate an adjacent area. Guidance indication light sources, which can be lasers, can emit beams in different colors to provide threat level indications. Plural emergency lighting devices can cooperate to guide a building occupant by providing directional indications on recipient surfaces.

A marine lamp includes an LED and a heat sink that removes heat from the LED. A lens assembly is associated with the LED and collects the energy from the LED and compresses the light into a high intensity beam. The beam strikes a secondary reflective surface which spreads the light into a desired output distribution. In one particular application, the desired output distribution has a ring-like distribution with a primary light beam at approximately 60 degrees from mounting surface normal.

A vehicular lamp includes a lamp source, a lamp body accommodating the lamp source, and a lens attached to the lamp body. The lamp body has an abutment surface on the top portion of a peripheral wall, which is configured to rise in a direction of an optical axis of the light source along a peripheral edge of the lamp body. The abutment surface of the lamp body is configured to incline to the optical axis. Similary, the lens has an abutment surface corresponding to the abutment surface of the lamp body along a peripheral portion of the lens. In this case, the abutment surface of the lens is configured within the dimention of an outer surface of the lens so as not to protrude over the outer surface. The abutment surfaces of the lamp body and the lens are integrally jointed together by laser walding.

A light source, suitable for use in a high-speed, continuous transport microfilm imaging system, includes an LED emitter element thermally coupled to a heat sink and is mounted within a light source housing. A light output opening in the light source housing, further defined by a narrow width light transfer channel, defines a narrow width active illumination area on the microfilm media. An optical diffusion plate, providing for a randomized directional distribution of light emitted by the LED emitter element, is mounted within the light source housing in an optical path extending between the light output opening and the LED emitter element. A switched current source is coupled to the LED emitter element to enable strobed operation synchronous with the periodic operation of a line imaging camera. The LED emitter element can be construed as a linear micro-strip array of LED elements. A cylindrical lens can be place in the optical path between the LED emitter element and diffusion plate to narrow and increase the intensity of light incident on and transmitted through the diffusion plate.

In a method for exposing an object to light and an exposure apparatus for performing the method, projection lights having image information may be produced. The projection lights may be projected onto the film on the substrate and travel along separately advancing paths. The advancing paths may not intersect with each other. To produce the projection light, illumination light beams proceeding along separately advancing paths may be produced. Thereafter, reticle patterns may transmit the illumination light beams. The reticle patterns may move in a first direction, and the substrate may move in a second direction opposite the first direction. The illumination light beams may be produced by separating an initial light. The projection lights may be projected onto the film at the same time or different times.

An error detection / correction system provides an electronic circuit detecting and correcting transmission errors using linear programming. Linear programming techniques are made practical for real-time error correction and decoding by dividing the linear programming problem into independent parallelizable problems so that separate independent portions of the electronic circuit may simultaneously address solutions related to individual bits and / or parity rules. Linear programming is believed to avoid error floors inherent in conventional belief propagation error detection and correction techniques providing a decoding system suitable for high reliability applications.

An infrared heating apparatus includes an infrared emitter with a coiled resistive wire embedded in a ceramic refractory material so that a first portion of the resistive wire is exposed and a second portion of the resistive wire is enclosed by the ceramic refractory material, such that the first portion forms an array of arcs that protrude above the ceramic refractory material.
