Title: Route generation in a vehicle navigation system
Inventor: TAMAI HARUHISA
IPC: G08G1/0969
Filed: 1997-12-12
Abstract: Methods and apparatus for generation of a route from a source location to a final destination are described. According to one embodiment, a two-ended search is performed based on the principles of the A* algorithm.  That is, two routes are simultaneously generated, one from the source to the destination, and one from the destination to the source. According to another embodiment, a route generation algorithm determines when to stop searching for route candidates.  The algorithm searches a map database for a first number of iterations thereby generating a first route candidate.  After generation of the first route candidate, searching of the map database is terminated after a second number of additional iterations.  A best route candidate is then selected as the route.
Patent CA-2224919-A1 (CA)
Inventor: LAWLOR MICHAEL
IPC: H01Q1/12
Filed: 1997-12-16
Abstract: A major problem with current satellite dish installations is that wind has a tendency to cause the satellite dish to come out of alignment with the satellite. This results in bad image reception or, in most cases, failure of the dish to receiveinformation from the satellite. Once misaligned, the satellite has to be re-focused by a technician skilled in satellite dish installation. The invention is a digital satellite dish stabilizer that eliminates the effects of wind and other elements on dish alignment with a satellite in geosynchronous orbit. The satellite dish stabilizer consists of a steel rod which connects the satellite dish to the mounting surface through the use of a surface mounting flange and a dish connection unit. The surface mounting flange is attached to the mounting surface via mounting screws. The dish connection unit is attached to the satellite dish. A steel rod connects the surface mounting flange to the dish connection unit. The surface mounting flange, dish connection unit and steel rod are attached in series and form the stabilizer for the satellite dish. There is preferably a satellite dish stabilizer supporting each side of the satellite dish, i.e. there is a surface mounting flange, dish connection unit and steel rod on both sides of the satellite dish.

IPC: F02B25/20
Filed: 1998-03-20
Abstract: To realize a reduction in the size of a cylinder block by simplifying the structure of an exhaust control valve, and to realize smooth flow of exhaust gases. There is provided an exhaust path for connecting to an exhaust port 39, comprising a first path 44 extending in a direction orthogonal to the central axis of the exhaust port 39, and a second path 43 connecting the first path 44 and the exhaust port 39, and a control valve 40 is provided in the first path 44. The rotational axis of the exhaust control valve 40 is parallel to a direction in which the first path 44 extends. The surface area of an opening 45 connecting the first path 44 and the second path 43 is variable as the exhaust control valve 40 rotates, so as to carry out control by activated heat atmosphere combustion and control of exhaust timing, etc. This makes it no longer necessary to provide a hollow section for housing an exhaust control valve at a position close to the exhaust port of the cylinder, or a bearing for supporting the exhaust control valve, and it is possible to reduce the size of a cylinder block and to realize smooth flow of exhaust gases by making the inner peripheral surface of an exhaust path smooth.

Inventor: JORDAN JEFF P
IPC: B63H11/08
Filed: 1996-12-20
Abstract: An improved water jet propulsion system (10) for a jet propelled watercraft (89) is disclosed designed to operate more efficiently. The improved propulsion system (10) includes an adjustable water inlet duct (17), a larger pump (40) and an adjustable discharge nozzle (62). The inlet duct (17) includes a hydraulically efficient inlet tunnel (18) with an adjustable entrance opening (19) which adjusts in size according to the velocity of the watercraft in the body of water and the flow of water through the system.  Using the inlet tunnel (18) and the adjustable grate structure (22), the total dynamic head of the incoming water may be recovered at the pump (40). The pump is larger than typical pumps used on jet propulsion systems so that a greater flow of water at low head pressure may be delivered to the adjustable discharge nozzle (62). The adjustable feature on the discharge nozzle (62) enables the flow through the system to be adjusted so that the hydraulic conditions on the pump (40) are maintained at all boat speeds and all shaft (44) rpms.

Title: A radially supported polytetrafluoroethylene vascular graft
Inventor: LAGUNA ALVARO J
IPC: A61F2/06
Filed: 1996-12-04
Abstract: A tube of porous PTFE having at least two first and at least two second regions wherein the at least two first regions have a greater density than the at least two second regions. For tubes of porous expanded PTFE having a microstructure of nodes interconnected by fibrils, the at least two first regions have a mean fibril length that is less than that of the at least two second regions. Preferably the regions are arranged in the form of ring-shaped segments of the tube wherein denser segments alternate along the length of the tube with less dense segments. Other arrangements between the different regions are possible; for example, the regions may be oriented in a spiral relationship with each other along the length of the tube. The porous PTFE tubes of the present invention have excellent radial compression resistance without requiring additional exterior reinforcing members due to the presence of the denser regions that are provided with a circumferential orientation. Tubes of this type are anticipated to be useful as vascular grafts and particularly as intraluminal vascular grafts. When provided as an intraluminal graft, the tube may also optionally be manufactured to be circumferentially distensible to a larger diameter up to a maximum diameter beyond which it will not distend during normal use; such a tube can also be made to recoil minimally on the release of the distending force.
