Abstract: Optical mirror coatings are used for high-temperature diffusion barriers and mirror shaping. Certain materials for use as high-temperature diffusion barriers under optical mirror coatings include metals that have high melting and/or boiling points and amorphous and partially recrystallized inorganic amorphous materials that have high glass transition temperatures (Tg). Candidate metals are selected based upon the boiling point or a combination of melting point and boiling point. Candidate amorphous and partially recrystallized inorganic amorphous materials are selected based upon the glass transition temperature. Optical mirrors having such high-temperature diffusion barriers maintain reflectivity when exposed to elevated temperatures, and are particularly useful in optical Micro Electro-Mechanical Systems (MEMS) that are exposed to high-temperature manufacturing processes. Optical mirrors are shaped using tensile and/or compressive films.

Abstract: A furnace exhaust remediation unit comprises an auxiliary combustion chamber with a gas burner assembly optimized for efficient and substantially complete combustion of pollutants, for example, waxy hydrocarbons emitted as binder/lubricant substances are driven off in sintering of green powdered-metal parts. The rate of flow of air and exhaust through the combustion chamber are controlled, permitting control of the average residence time of the emissions, ensuring substantially complete combustion. The burner is arranged such that it provides a high-energy exhaust stream directed tangentially into the combustion chamber, so that a spiral motion is provided to the combustible pollutants, improving mixing and heat transfer and thus ensuring efficient combustion of the vaporized hydrocarbon emissions. The system has a universal modular construction where a burn chamber module; a burn chamber extension module and slide gate damper assembly module are provided.

Abstract: A wafer cap protects micro electromechanical system (“MEMS”) structures during a dicing of a MEMS wafer to produce individual MEMS dies. A MEMS wafer is prepared having a plurality of MEMS structure sites thereon. Upon the MEMS wafer, the wafer cap is mounted to produce a laminated MEMS wafer. The wafer cap is recessed in areas corresponding to locations of the MEMS structure sites on the MEMS wafer. The capped MEMS wafer can be diced into a plurality of MEMS dies without causing damage to or contaminating the MEMS die.

Abstract: A central management system manages a plurality of computer jukeboxes and communicates compressed digital data with each jukebox via a transmission link. The management system also includes a host computer that maintains a master set of compressed digital data representing a plurality of songs, song associated graphics, and song identity information. Each jukebox includes a storage unit that is capable of storing a subset of the master set and a processing circuit having a decompression circuit. The processing circuit controls the operation and flow of digital data into and out of the jukebox through the transmission link as well as a visual song information display, user song selection keys, a money detector, and an audio reproduction circuit coupled to a speaker system so as to provide audio output to users of the jukebox.

Abstract: A die has a part that is sealed with a cap. The seal can be hermetic or non-hermetic. If hermetic, a layer of glass or metal is formed in the surface of the die, and the cap has a layer of glass or metal at a peripheral area so that, when heated, the layers form a hermetic seal. A non-hermetic seal can be formed by bonding a cap with a patterned adhesive. The cap, which can be silicon or can be a metal paddle, is electrically coupled to a fixed voltage to shield the part of the die.

Abstract: The present invention provides an apparatus for playing and method of controlling a computerized dart game of simulated tug-of-war. The method generates on a display a goal graphic, at least one player graphic, and at least one challenger graphic. The goal graphic typically includes a first side on which the player graphic is initially displayed and a second side on which the challenger graphic is initially displayed. The method monitors the segments in at least one electronic dart board for hits by darts and determines at least one offset value associated with a segment hit by a dart. The offset value may represent the sum of one or more hits by a player, the sum of one or more hits by a challenger, of the difference between one or more by a player and hits by a challenger. In a single player game, the method itself may generate a random challenger value.
