Inventor: ROBERT MICHEL
IPC: B23K35/14
Filed: 1997-07-08
Abstract: The disclosed invention provides for a method of manufacturing solder columns for particular use in attaching substrates to a printed circuit board. The method results in columns of homogeneous composition and thus overcomes problems associated with the phenomena of segregation. The method includes the steps of forming particles of the metal composition to be used for the columns from a molten source of the composition. The solid particles are then formed into segments of homogeneous composition by drawing ingots of the composition into wire and severing the wire into segments.

Title: Multimedia call signalling system and method
Inventor: WONG CHI-KEUNG
IPC: H04L12/58
Filed: 1998-10-13
Abstract: A system and method for performing call signalling for multimedia call setups. A user equipped with calling terminals of various types may initiate a call from any of these terminals, and the call is intercepted and handled by the system. A calling agent looks up an E-mail address for the called party, and sends a setup request E-mail to a called agent associated with the called party. The called agent determines the current terminal that the callee is using, and together with the calling agent a call medium and other parameters are established. Then a connection is made between a calling terminal and the current terminal. This provides a generic signalling system for a callee using a wireline terminal, wireless terminal, or H.323 terminal to be connected to a called terminal also being any one of these or other types.

Title: Three-color sensor with a pin-layer sequence or a nip-layer sequence
Inventor: FOELSCH JOACHIM
IPC: H01L31/10
Filed: 1997-04-07
Abstract: A structure of several i-layers is limited on one side by a p-layer and on the other side by an n-layer. The structure has means that form said i-layers in such a way that at least in the boundary area between two adjacent i-layers (i?I¿, i?II¿), seen in the light incidence direction, the bandgap E¿g? (I) of the first i-layer (i?I¿) closer to the light input side is larger than the bandgap E¿g? (II) of the second i-layer (i?II¿) adjacent to the first and further removed from the light input side. In addition, in the boundary area between two adjacent i-layers (i?I¿, i?II¿), in the direction from the p-layer to the n-layer, the product µ?(I) of the i-layer (i?I¿) further removed from the n-layer is larger than the product µ?(II) of the i-layer (i?II¿) closer to the n-layer. A structure is thus obtained for forming a colour sensor which generates signals which need to be superimposed to a lesser extent for image processing. The structure is preferably designed as a pin- or nip-structure.

Title: Color display device
Inventor: OKITA MASAYA
IPC: G02F1/13357
Filed: 1998-12-11
Abstract: A color display device has a single light guiding plate, and first, second and third light sources that respectively independently exhibit three primary colors. On a one end surface of the light guiding plate there are disposed the first and second light sources that exhibit two different ones of the three primary colors . On the other end surface side of the light guiding plate there is disposed the third light source that exhibits the remaining one primary color. Since the light guiding means is needed only one in number, the structure can be simplified and miniaturized. Also, on the one end surface of the light guiding means there are disposed, of the three light sources exhibiting the three primary colors, the first and second light sources that exhibit two different ones of the three primary colors. And, on the other end surface side of the light guiding means there is disposed the third light source that exhibits the remaining one primary color. Therefore, the probability that the light which enters into the light guiding means from one light source is hindered by another light source decreases. Accordingly, the loss of the light becomes lessened and the amount of light emission increases.

Title: Frame relay network featuring frame relay nodes with controlled oversubscribed bandwidth trunks
Inventor: LICHT ROBERT C
IPC: H04L12/56
Filed: 1999-01-29
Abstract: A frame relay network has a network management system in combination with frame relay nodes. The network management system provides frame relay oversubscription trunk and connection parameter signals to the frame relay nodes. The network management system uses a graphical user software interface program for receiving frame relay oversubscription trunk and connection parameters from a network supervisor that are formatted into the frame relay oversubscription trunk and connection parameter signals. The frame relay nodes respond to the frame relay oversubscription trunk and connection parameter signals, for providing an frame relay oversubscription connection control signal from one frame relay node to another frame relay node depending on the frame relay oversubscription trunk and connection parameter signals. In operation, the trunk line has multiple virtual connections communicating the frame relay oversubscribed data between the frame relay nodes.      Each frame relay node includes a node control board, one or more frame relay line interface boards, and a control bus for connecting the node control board to the one or more frame relay line interface boards. The one or more frame relay line interface boards may include either a frame relay low speed line interface board, a frame relay medium speed line interface board, a frame relay high speed line interface board, or a combination thereof.
Patent CA-2259544-A1 (CA)
Title: Extensible indexing
Inventor: NORI ANIL
IPC: G06F17/30
Filed: 1997-07-01
Abstract: A method and apparatus for processing a query in a database system using index types that are not built into the database system are disclosed. Routines for managing an index structure that is not supported by a database system are generated. Data that identify the routines are submitted to the database system, thereby "registering" the index types with the database system. In response to statements issued to the database system by a client, the database system call the routines, causing the routines to create an index structure using data from a data container in the database, and to generate data that indicates which data in the data container satisfies a query issued by the client. The routines of the registered index type extend the indexing capabilities of the database systems and one or more such index types can be registered with the database system. The index structure managed by the routines may be maintained within segments of the database, and the segments may be accessed as index-only tables. Storing a row of data in a database using index-only tables involves storing in a leaf node an index entry that includes a key value along with all other values in the row of data. If the row of data exceeds a predetermined size, then a portion of the row data is stored in an overflow area. Retrieving a row of data from an index-only table for a user-supplied key involves identifying a leaf node for the key, and reading a row of data from the index entry and any remaining portion from the overflow area when the row exceeds the predetermined size.
