Title: Multimedia multipoint telecommunications reservations systems
Inventor: SEMAAN GHASSAN
IPC: H04L29/06
Filed: 1997-01-16
Abstract: Reservation controllers and reservation systems for reservation of access to multimedia multipoint telecommunications servers (MCUs) are provided. The reservation controller establishes a reservation domain having a reservation request channel on which reservation applications may be taken. An ongoing reservation conference is associated with the reservation domain. The reservation domain is preferably established within the ITU-T T.120 standard series requirements, with multipoint connection under T.122/T.125, and interface to profiles such as ISDN, TCP/IP, X.25, ATM, Ethernet, etc., under T.123. A user makes reservations for MCU resources by knowing the address of the reservation domain, attaching himself to the reservation domain, joining the reservation conference via establishing one or more transport connections, and sending the reservation request onto the reservation request channel. All reservation requests forwarded onto the reservation request channel are received and acted upon by the reservation controller. Reservation systems utilizing a plurality of reservation controllers are also disclosed, where the reservation controllers are part of the same domain, are arranged in multiple domains on a single level, or are arranged in hierarchical domains. Where more than one reservation domain is established, same-level or hierarchical level bridges are established.

Title: Location based selective distribution of generally broadcast information
Inventor: ERNST DARRELL E
IPC: H04H20/00
Filed: 1995-08-10
Abstract: A system for determining whether information broadcast by a general transmitter is relevant to a particular user based on the location, velocity and/or time of an object of interest includes a remote terminal (110), a general broadcasting unit (200), a transmitter (190) at the general broadcasting unit for broadcasting messages including a segment comprising a region, a velocity and/or a time corresponding to an event, as well as an event specific tag, and storage (130) for storing selection criteria including current position, time and/or velocity information of the use and/or manually entered data of interest.     The selection criteria may also include event specific tags.     The receiver (120) at the remote terminal (110) receives the messages from the transmitter (190) at the general broadcasting unit (200). A navigational receiver (121) may also be used to acquire navigational information from an appropriate external source. A matching processor (140) at the remote terminal (110) evaluates the segment in the messages, determines if the segment sufficiently matched the stored election criteria and outputs a match signal. A processor (150) in the remote unit (110) receives the match signal, and processes and disseminates the message in accordance with the match signal.

Abstract: A three-dimensional cloth material having a superior touch and durability and a method of manufacturing a three-dimensional material which has a low production cost and a high productivity. A cloth layer (85) having a print pattern, a foamed body (87) and a fiber material (88), of which one surface is subjected to laminating of a plastic film, are placed and positioned on an elastic sheet (86). The cloth layer (85), foamed body (87), fiber material (88) and the elastic sheet (86) are integrally subjected to pressurized compression for a predetermined period of time by upper and lower dies (80, 82) while the foamed body (87) remains in visco-elastically flowing state. As a result, the foamed body (87) is secured to a back surface of the cloth layer (85) to be three-dimensionally formed in registry with a profile of the print pattern to support the three-dimensional pattern of the cloth layer (85). The plastic film of the fiber material (88) is secured at its entire surface to the foamed body (87), and only a peripheral portion of the fiber material (88) is fused to the back surface of the cloth layer by subsequent heating. As a result, the foamed body (87) is completely between the cloth and the fiber material.

Abstract: An improved dilatation catheter is described which has an oblong transverse cross section along essentially its entire length and a stiffening mandrel (23) extending within the proximal section and a part of the distal portion.  In a presently preferred embodiment, the large dimension of the proximal section (24) of the catheter shaft (11) is greater than the corresponding large dimension of the distal shaft section (25) and a tapered region is provided between the proximal and distal shaft sections. The stiffening mandrel (23) has a proximal section with at least one dimension greater than the corresponding dimension of the distal section and a tapered transition section (26) is provided between the proximal and distal mandrel sections. The length of the proximal section of the mandrel is such so as to locate the tapered transition section (26) of the mandrel within the proximal section of the catheter shaft. This results in a smoother overall transition between the proximal and distal sections of the catheter shaft.

Title: Cellular and serum protein anchors for diagnostic imaging
Inventor: EZRIN ALAN M
IPC: A61K51/08
Filed: 1997-01-07
Abstract: Methods of non-invasive diagnosis are provided employing bifunctional anchor molecules. The bifunctional anchor molecules have a functional group capable of activation which, when activated, may form a covalent bond with a reactive functionality on a target protein present in the mammalian vascular system, thereby "anchoring" the molecule to that target protein. The bifunctional anchors are also conjugated, either directly or indirectly, to a diagnostic agent of interest which provides the ability to diagnostically and noninvasively image the mammalian vascular space. Vascular targets include both cellular- and noncellular-associated proteins present in the mammalian vascular system. The methods find use for numerous applications arising from the ability to diagnostically image the mammalian vascular space over an extended period of time or to preferentially diagnostically image only a specific cell type or compartment of the mammalian vascular space.
