Title: Drop from front of buffer policy in feedback networks
Inventor: OTT TEUNIS JAN
IPC: H04L12/56
Filed: 1996-03-05
Granted: 2002-12-17
Abstract: A method for transmitting packets or cells (or both) in a communications network (10) is disclosed. The packets or cells are transmitted along a forward communications path in a network from a source node (h1) via one or more intermediary nodes (r1, x1, r6 and r2) to a destination node (h4). At the intermediary nodes (r1, x1, r5 or r2), the packets or cells are received in a buffer (38 or 42-1 to 42-4). The packets or cells are transmitted along the forward communications path according to a communications schedule. In the presence of congestion at one of the intermediary nodes (x1), an indication of the congestion (302-342) is provided to the destination nodes (h4) of the first packets to be transmitted according to the schedule. An indication of the congestion of the first packets or cells is provided by the destination nodes (h4) of the first packets or cells to the source nodes (h1) of the first packets or cells via a feedback communications path.

Title: Inhibition of c. difficile infections by indigestible oligosaccharides
Inventor: MEULBROEK JONATHAN ALLAN
IPC: A61K33/00
Filed: 1996-04-04
Granted: 2002-07-30
Abstract: The primary etiology of antibiotic-associated diarrhea (also known as pseudomembranous colitis) has been recognized as Clostridium difficile. It i s believed that the indigenous microflora of a healthy individual suppresses t he normally present C. difficile. However, when the indigenous microflora are disrupted (e.g., during antibiotic treatment) overgrowth of C. difficile may  occur causing diarrhea and colitis. Treatment of C. difficile with antibioti cs has proven effective, but many times relapse occurs; and dehydration due to diarrhea is an exacerbating problem. It has been suggested that normalizatio n of the microflora will inhibit C. difficile relapse. Indigestible oligosaccharides have been shown to inhibit C. difficile infection. An oral rehydration solution containing such indigestible oligosaccharides also provides fluid and electrolyte replacement.

Title: Electrochemical biosensor test strip
Inventor: HUBBARD SCOTT E
IPC: G01N27/327
Filed: 1996-06-28
Granted: 2008-05-06
Abstract: An electrochemical biosensor test strip (1) that has a minimum volume blood sample requirement of about 9 microliters. The test strip has working (4) and counter (5) electrodes that are substantially the same size and made of the same electrically conducting material placed on a first insulating substrate (2). Overlaying the electrodes is a second insulating substrate (3), which includes a cutout portion (8) that forms a reagent well. The cutout portion exposes a smaller area of the counter electrode than the working electrode. A reagent for analysis of an analyte substantially covers the exposed areas of working and counter electrodes in the reagent well. Overlaying the reagent well and affixed to the second insulating substrate is a spreading mesh (13) that is impregnated with a surfactant. The small cutout portion of 4 millimeters by 4.2 millimeters, small mesh of 6 millimeters by 5.8 millimeters, and small amount of reagent, 4 microliters before drying, allow the test strip to analyze a whole blood sample of about 9 microliters.

Abstract: In a multicast capable IP network implemented over an ATM network, each client terminal on a multimedia conference, for each media type it transmits, is assigned a multicast IP address and a port number (together known as a socket) on which to transmit packets, wherein each assigned multicast IP address is unique and different than the multicast IP address assigned to any other client for any media type. Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. A single special purpose Multicast Address Resolution System (MARS) server is associated with the conference when the conference is established. Each client terminal uses that MARS server, whether on the same or different IP sub-networks, but on a common ATM network, for purposes of mapping the multicast IP addresses used in the conference into a set of unicast ATM endpoint addresses used by the ATM-connected client terminals. Similarly, when a specific conference uses a Multicast Server, a single special purpose Multicast Server is used for all clients on the conference, whether on the same or different IP sub-networks, for purposes of establishing point-to-multipoint ATM connections to the conference endpoints.

Granted: 2003-04-08
Abstract: A disposable, absorbent garment, such as a diaper, having an absorbent core (14) and stretchable, substantially liquid impermeable web (12). The core (14) is attached to the web (12) by a strip of adhesive (32) extending in a longitudinal direction along the bottom surface of the core (14). The web (12) is folded around the exterior of the core (14) and includes notches formed in opposing sides of the crotch portion of the web (12). When folded about the core (14), the notched areas form a longitudinally extending opening along the top surface of the core (14). A plurality of elastic bands are affixed along  the crotch portion of the web (12) so as to extend substantially parallel to, but inwardly of the notched areas. The elastic bands constrict the web (12) adjacent the notches to form cuffs which fit snugly about the wearer's legs. Adhesive tabs, or another similar closure device, i s attached on opposite sides of the web (12) to hold the garment together about the wearer's torso. Alternatively, opposing sides of the garment may be sealed together to form a pant. Elastomeric material is affixed to strategic positions of the web (12) to increase the elastic force of the web (12) when stretched, to enable the garment to better conform to the wearer's body. Optionally, heat shrinkable film may be dispos ed about the opening formed by the notches in order to raise the edges of the opening and form a pocket for containing solid waste materials.
