Title: Method and apparatus for querying a database containing disjunctive information
Inventor: LIBKIN LEONID
IPC: G06F17/30
Filed: 1996-04-18
Abstract: A method and  apparatus for querying a disjunctive database is disclosed.  An annotated object, which defines a complete object which is a unique element of the normal form of the database,  is stored and maintained in memory. A complete object is created using the annotated object, and is stored in memory.  A query is run against the complete object.  If continued processing is required, a next function produces a next annotated object, which represents another unique element of the normal form of the database.  The next annotated object is stored in memory, overwriting the previous annotated object.  A complete object is then created using the next annotated object and is stored in memory, overwriting the previous complete object. The query is then applied to the complete object stored in memory.  By processing the elements of the normal form one at a time and reusing memory spaces, the present invention has a polynomial space requirement. The invention also allows processing to begin from a pre-defined annotated object, either user defined or random.  A user defined annotated object may define certain sub-objects which are not to be processed.  Further, processing may terminate with the last processed annotated object as an output.

Patent CA-2218607-A1 (CA)
Inventor: CHEN XUEMIN
IPC: H04N7/50
Filed: 1997-10-20
Abstract: In a stereoscopic video transmission system, video pictures of lower and enhancement layers are transmitted in a particular order such that the number of pictures which must be temporarily stored prior to presentation is minimized. Furthermore, a decode time stamp (DTS) and presentation time stamp (PTS) for each picture can be determined to provide synchronization between the lower layer and enhancement layer pictures. Decoding may occur either sequentially or in parallel. In particular, a method is presented where the enhancement layer includes disparity-predicted pictures which are predicted using corresponding lower layer pictures. The video pictures are ordered such that the disparity-predicted enhancement layer pictures are transmitted after the corresponding respective lower layer pictures. The scheme is illustrated with a number of different specific examples.

Title: Reflective optical switch
Inventor: KEYWORTH BARRIE
IPC: G02B26/02
Filed: 1997-11-14
Abstract: A binary 1xn optical deflection switch has one input port, n two state switchable devices and 2n output ports. A switching mechanism is provided wherein a path length between two adjacent reflective surfaces can be varied by effectively moving a reflective surface. This is achieved by providing a first air glass interface (reflection means) where total internal reflection will occur, and having the capability of selectively providing a second glass block coupled to the first air glass interface to provide a new distant air glass interface at a distance from the first one equivalent to the thickness of the second glass block. When the second air glass interface is provided, the first air glass interface no longer exists and incident light follows a second path. When the second glass block is lifted off, the first air glass interface is once again present and a beam of light then follows a first path, reflecting off of the first air glass interface. Therefore by effectively moving the refection means, a beam of light is steered along different paths to selected output ports.

Title: Method and apparatus for processing a tubular container
Inventor: IMAIZUMI YASUYUKI
IPC: B29B13/02
Filed: 1997-04-24
Abstract: There is provided a method and apparatus for processing a thinly walled tube of thermoplastic resin to produce a tubular container having an inwardly directed flange section in a hole formed at an end of the thinly walled tube. In the first step, the thinly walled tube is secured to a tube holder provided with a male mold for molding the flange section in the hole and forming an opening located inside the flange section. The front end of the thinly walled tube projects by a predetermined distance from the front end of the tube holder. Then, in the second step, hot air is blown to an inner wall surface of the thinly walled tube at and near the front end thereof and the outer wall surface of the thinly walled tube is cooled also at and the front end thereof, to produce a temperature difference between an inside and an outside of the thinly walled tube, so as to deform the front end of the thinly walled tube into a flange projecting radially. When the inner wall surface is heated to a temperature lower than a melting point of the inner layer, the front end of the thinly walled tube is deformed inwardly. When the inner wall surface is heated to a temperature higher than the melting point of the inner layer, the front end of the thinly walled tube is deformed outwardly. Finally, in the third step, the deformed front end of the thinly walled tube is molded into the flange section showing a predetermined shape and forming the opening located inside the flange section by means of a female mold cooperating with said male mold.
