Title: Advance notification system for use with vehicular transportation
Inventor: JONES MARTIN KELLY
IPC: G08G1/123
Filed: 1996-10-04
Abstract: An advance notification system (10) and method notifies system users of the impending arrival of a transportation vehicle (19), for example, a school bus, at a particular vehicle stop. The system (10) generally includes an on-board vehicle control unit (VCU) (12) for each vehicle (19) and a base station control unit (BSCU) (14) for making telephone calls to users in order to inform the users when the vehicle (19) is a certain predefined time period and/or distance away from the vehicle stop. The VCU (12) compares elapsed time and/or travelled distance to the programmed scheduled time and/or travelled distance to determine if the vehicle (19) is on schedule. If the vehicle (19) is behind or ahead of schedule, the VCU (12) calls the BSCU (14), which then adjusts its calling schedule accordingly. Significantly, a calling report generator (11) in the BSCU (14) allows a system user to solicit a calling report from the BSCU (14) that indicates the time(s) and outcome(s) of any previous notification attempt(s) by the BSCU  (14) to the user telephone (29).

Title: Method for improving co-channel interference in a cellular system
Inventor: HASSAN AMER
IPC: H04B7/26
Filed: 1997-10-03
Abstract: A fractional loading scheme is used to improve the spectral efficiency of a cellular system, and therefore increase the number of users that the system can support. The fractional loading scheme allows only a fraction of the total number of available communication channels within each cell to be used simultaneously. Thus, each cell is deliberately underloaded to operate at less than its full capacity. The underloading of the individual cells reduces the spectral efficiency within each cell. However, the underloading of each cell means that there will be fewer interfering users at any given time so that the co-channel interference is reduced. This reduction in co-channel interference allows the reuse distance between co-channel cells to be reduced thereby increasing the reuse of frequencies throughout the system resulting in an increase in spectral efficiency in the system as a whole.

Title: Technique for manufacturing hose
Inventor: PYLE KEVIN JAMES
IPC: B29C48/09
Filed: 1997-09-08
Abstract: Hoses are often reinforced with fabric to improve their performance characteristics, such as burst strength. For instance, radiator hose used in automative applications is generally reinforced with continuous yarn. However, it is a labor-intensive process to manufacture such hoses which include fiber reinforcements. A substantial amount of material waste also generally occurs in the manufacture of such fiber-reinforced hose. By utilizing the technique of this invention, hose which has a high level of burst strength can be manufactured without including continuous yarn reinforcement. This invention specifically reveals a process for manufacturing a hose which comprises (1) extruding a rubber composition into the form of a tube, wherein the rubber composition is comprised of (a) a polypropylene/polyethylene alloy comprised of (i) a low melt index polyethylene and (ii) polypropylene, wherein the polypropylene is homogeneously dispersed throughout the polyethylene in the polypropylene/polyethylene alloy, (b) an EPDM rubber, (c) carbon black, (d) at least one curative, (e) zinc oxide, (f) a processing oil and (g) stearic acid;  (2) shaping the tube into the geometric form desired for the hose; and (3) curing the rubber composition at a temperature within the range of 130 ~C to 210 ~C to produce the hose.

Title: 3d mesh compression and coding
Inventor: KUO CHUNG-CHIEH JAY
IPC: G06T19/00
Filed: 1999-01-29
Abstract: Single and progressive-resolution coding algorithms for the compression of 3-D polyhedral meshes are disclosed. In the single-resolution mode, the mesh topology (or connectivity) is encoded by a constructive traversing approach applied to the dual graph of the original mesh while the mesh geometry is encoded by successive quantization and the bit-plane coding (achieved by context arithmetic coding). In the progressive-resolution mode, the mesh is represented by a coarse approximation (i.e., the base mesh) and a sequence of refinements. Both the base mesh and the refinement operations are entropy coded so that a series of mesh models of continuously varying resolutions can be constructed from the coded bit stream. Topological and geometrical data of a 3-D mesh are encoded separately according to their importance and then integrated into a single bit stream. In decoding, the decoder finds from the bit stream the most important information and gradually adds finer detailed information to provide a more complete 3-D graphic model. The decoder can stop at any point while giving a reasonable reconstruction of the original model. The disclosed algorithm was applied to complicated 3-D meshes and achieved a compression ratio of 20:1 while maintaining a good graphic quality.

Title: System and method for detecting unauthorized use of a cellular telephone
Inventor: THURLEY RICHARD N
IPC: H04W12/06
Filed: 1998-06-10
Abstract: A system and method for detecting and preventing cellular fraud in a cellular network. The network includes a database such as a home location register that stores a listing of potential terminating numbers that the authorized user is allowed to call. Therefore, whenever a call is initiated by a cellular telephone using the identification number of the authorized user, the called number is compared to the listing. If the called number is in the listing, the call completes normally. If not, an additional level of security can be provided. For example, the caller may be prompted for a security code, the caller may be transferred to a service center, or the caller may be transferred to a cellular-fraud-prevention task force. If, in the first example, the caller supplies the correct security code, then it is assumed that he is the authorized user and the call completes normally. Furthermore, the called number may then be added to the listing. Otherwise, it is assumed that the caller is a fraudulent user and is handled accordingly.

Filed: 2000-04-25
Abstract: A continuous push-pull quick release clamp for resisting axial movement of a body along a shaft comprising a plate having a spring pivotally mounted at one end and an opposite end with a diameter sized to receive the shaft. The plate also includes an aperture sized to be received on the shaft adjacent to the body. In use, the coil spring is slid onto the shaft adjacent to the body and the plate is pivoted with respect to the end of the wire opposite the coil spring so that the aperture in the plate is received onto the shaft in an axially spaced relationship to the coil spring.  As the body acts axially on the coil spring, the force imparted by the body is transmitted through the coil spring to the opposite end of the wire where the force tends to rotate the elongated plate in a direction which causes edges of the aperture to be urged against the shaft creating a retaining force between the plate and the shaft.  The quick release clamp is specifically applicable to a label application apparatus having a supply reel rotatably mounted to a main housing and having a continuous label web thereon, wherein the clamp adjustably retains the supply reel on a supply reel shaft.
