Abstract: A micro-retarder plate using a single plate with phase retardation. The plate with phase retardation having a pattern that further comprises a plurality of first retardation state areas and second retardation state areas alternating with each other is formed on the micro-retarder plate. The pattern is formed using an infra-red laser to expose the plate with phase retardation, or using a circuit board with a pattern of electrothermal resistor thereon in contact with the plate of phase retardation. The linear polarized lights with direction of polarization being 45 degrees to the stretching direction of the retardation film passing through the first retardation state areas and the second retardation state areas are perpendicular to each other. The micro-retarder is laminated between two protection layers with index matching glue to remove the scattering effect caused by the heat process.

Abstract: Disclosed is a method for high speed rerouting in a multi protocol label switching (MPLS) network which can minimize a packet loss and enable a fast rerouting of traffic so as to protect and recover a multi point to point LSP occupying most LSPs in the MPLS network. The method for high speed rerouting in a multi protocol label switching (MPLS) network, the method comprising the steps of controlling a traffic stream to flow in a reverse direction in a point where a node or link failure occurs by using a backup Label Switched Path (LSP) comprising an Explicitly Routed (ER) LSP having a reverse tree of a protected multi point to point LSP and an ingress LSR through an egress LSR.

Abstract: A back-lighted autostereoscopic display. A uniform light is emitted from a plane light source. A polarization plate is disposed in front of the plane light source to polarize the uniform light into a polarized light. A micro-moving window device is disposed in front of the polarization plate to selectively change the polarity of the polarized light into another type of polarization. A micro-optical device is located in front of the micro-moving window device, thereby both the polarized light changed and unchanged pass through the micro-optical device to travel further. An imaging apparatus is located in front of the micro-optical device, so that the lights are converged into the eyes of an observer. A liquid crystal display panel with a patterned half-wavelength phase retarder according to the even rows and odd rows of the interlaced image displayed on the liquid crystal display is located in front of the imaging apparatus to project the stereo-image to the observer.

Abstract: In a distributed database system, at least one of the databases operates as a transaction manager and provides transparent commit coordination between an application program and other connected databases. The transaction manager incorporates a commit alteration procedure which enables selection of either a single phase commit protocol or a two phase commit protocol with respect to each database, during operation of the distributed system. The transaction manager establishes a commit protocol for each connected database; responds to a command from an application program by overriding a commit protocol previously established for a selected database and establishes another commit protocol for the selected database; performs a transaction and utilizes the another commit protocol in connection with the transaction; and upon completion of the transaction as evidenced by a successful commit action, enables establishment of another commit protocol.

Abstract: A perfumed doll including a doll, an outer tubular member inserted into the doll, the outer tubular member being open at both ends thereof and provided with internal threads at an upper end thereof, a collar fixedly mounted on the upper end of the outer tubular member and formed with a neck at a central portion thereof, a sleeve having a neck snugly fitted into a lower end of the outer tubular member, an inner tubular member open at a top thereof, the inner tubular member being provided with an enlarged end at a bottom thereof and external threads at an upper end thereof, the inner tubular member being inserted into the outer tubular member with the external threads engaged with the internal threads, and a wick fitted within the inner tubular member and extending upwardly out of the collar.

Abstract: A system for managing database connections between concurrent user applications and a plurality of databases in a database processing system. This method minimizes the number of connections made to a database by allowing such connections to be shared by multiple applications. The concept of a shared versus exclusive connection is introduced and, depending on the user application, a connection manager automatically routes a database access request through either an existing shared connection or an exclusive connection. A single database access object is introduced that includes two types of methods for connecting to a specified database in two different simultaneous paths. First, a shared connection through a catalog server process is made to process schema query requests for definition retrieval. Secondly, another connection is made to retrieve and manipulate data from the database responsive to SQL execution requests.

Abstract: An electronic lock mechanism utilizing for the opening thereof a card-key upon which digital codes are imprinted. The digital codes are created by infrared light transmissive portions and infrared light non-transmissive portions on the card-key. The electronic lock mechamism determines the digital codes of the card-key by directing infrared light upon the surface of the card-key, and measuring the times in which the light passes through the infrared light transmissive portions of the card-key, and compares these digital codes with pre-selected digital codes. Only during those times in which the digital codes imprinted upon the card-key and the pre-selected digital codes are identical may the electronic lock mechanism unlock.
