Title: System and method for optimal virtual path capacity dimensioning with broadband traffic
Inventor: HOLENDER WLODEK
IPC: H04M3/00
Filed: 1996-07-11
Abstract: A general dimensioning method and system for allocating limited transmission resources to various virtual paths defined on top of a physical network. A two-level hierarchical structure is defined (figure) with a layer of one or more virtual paths on top of a layer of physical network elements. Traffic demand is specified for each virtual path and the Entropy Rate Function is used as a blocking measure.

Title: Parainfluenza virus glycoproteins and vaccines
Inventor: CATES GEORGE A
IPC: A61P37/04
Filed: 1996-09-23
Abstract: The hemagglutinin-neuraminidase (HN) and fusion (F) glycoproteins are coisolated and copurified from the parainfluenza virus type 1 (PIV-1) and parainfluenza virus type 3 (PIV-3). The HN and F glycoprotein are separately isolated and purified from parainfluenza virus type 2 (PIV-2). The glycoproteins formulated as vaccines, are highly immunogenic and protect relevant animal models against parainfluenza challenge. A vaccine containing the HN and F glycoproteins from PIV-3 was safe and immunogenic in adults and children. A trivalent vaccine containing HN and F glycoproteins from PIV-1, PIV-2 and PIV-3 generated an immune response capable of neutralizing each of the viruses.

Title: Mobility management system
Inventor: CHUAH MOOI CHOO
IPC: H04L12/56
Filed: 1998-10-08
Abstract: A wireless data network includes a wireless packet switched data network for end users that divides mobility management into local, micro, macro and global connection handover categories and minimizes handoff updates according to the handover category. The network integrates MAC handoff messages with network handoff messages. The network separately directs registration functions to a registration server and direct routing functions to inter-working function units. The network provides an intermediate XTunnel channel between a wireless hub (also called access hub AH) and an inter-working function unit (IWF unit) in a foreignnetwork, and it provides an IXTunnel channel between an inter-working function unit in a foreign network and an inter-working function unit in a home network. The network enhances the layer two tunneling protocol (L2TP) to support a mobile endsystem, and it performs network layer registration before the start of a PPP communication session.

Abstract: Compact dual focal length cameras are disclosed having wide angle and telephoto modes of operation. The ratio of telephoto to wide ratios is at least 3 to 1, but is typically higher so that the cameras can be used in conjunction with binoculars to take telephoto pictures that give the same visual appearance as when the same scenes are observed through binoculars. Compactness and increased focal length are achieved via four mirror (110, 116, 122, 90) arrangements one preferred embodiment of which wraps around the camera film plane (48), and uses a single constant angular velocity shutter (130) for providing both wide angle and telephoto exposure times. Compact, single-use, medium telephoto cameras are also disclosed.

Title: Flower holder with angled flower support
Inventor: O'CONNELL DONALD L
IPC: A01G5/04
Filed: 1999-01-08
Abstract: A holder for supporting flower arrangements has first and second compartments for receiving first and second water retaining foam blocks. When mounted on the holder, the first foam block has a top surface which is parallel to the bottom Wall of the first compartment. The second compartment has a bottom wall which intersects the bottom wall of the first compartment at an angle greater than zero, and the second foam block has a top surface which is inclined at such angle relative to the top surface of the first foam block so that the holder can be mounted on a support with surfaces intersecting at an angle and both surfaces will be covered.      Stems of flowers can be inserted orthogonally into the top surfaces of both the foam blocks to provide that flowers extend from the holder vertically and at such angle relative to the vertically extending flowers. One side surface of one foam block abuts a side surface of the other foam block and at least one of the blocks is tapered at its side to permit the abutting of the side surfaces and such orientation of the top surfaces of the blocks. A water receptacle underlies the bottoms of the compartments for holding any water which drains from the foam blocks by way of apertures in the bottom walls.
