Title: Method of and system for determining a route of travel by a vehicle
Inventor: DOYLE THOMAS F
IPC: G01C22/02
Filed: 1998-03-11
Abstract: A system and method for determining a route of travel and associated mileage of a vehicle is disclosed. The system records a vehicle's location and odometer reading, transmitted via satellite to a fixed station (40). The location data is provided to a processor which determines an estimated route of travel by the vehicle using a routing program (44). The estimated route is comprised of a plurality of position segments, each position segment having a corresponding mileage and average expected speed. The route of travel may be checked for accuracy by comparing the estimated route mileage to the odometer mileage (50). If a significant difference is found, a diagnostic procedure is performed (52, 58) which attempts to correct the mismatch by evaluating alternate routes of travel. Once the route of travel has been determined, the mileage travelled by the vehicle can be accurately determined and used for various computations. For example, state-imposed fuel taxes may be accurately calculated from the mileage information.

Title: Method of providing transfer capability on web-based interactive voice response services
Inventor: BALL THOMAS J
IPC: H04M3/58
Filed: 2000-03-13
Abstract: Interactive voice response (IVR) services are provided to an end user at a telephone terminal connected to the PSTN through a telephone/IP server that serves as an interface between the PSTN and an IP network such as the Internet. A  first IVR service is provided by a web server running a service logic for that service, which produces pages formatted in a phone markup language (PML) in response to an HTTP request sent over the IP network by the telephone/IP server to the web server at the URL address associated with the service. These pages represent an interactive dialog for that first service, which when received by the telephone/IP server, are translated and converted to audio by an interpreter for audio presentation to the end user. The end users responses, either verbal or touch-tone, to questions posed during the dialog are collected by the telephone/IP server, translated, and forwarded to the web server. Hyperlinks to a second IVR service offered on a web server at a different URL address are embedded and associated with a specific question or statement in a PML-formatted page produced by the first service.  When the end user affirmatively responds to that statement or question through a verbal or touch-tone input, the telephone/IP server translates that response as a "click" on the hyperlink and establishes a virtual connection to the hyperlinked URL address of the web server providing the second service. Further, information associated with the end users interaction with the first service, such as his identity, PIN, and/or zip code, is transferred to the second service by means of a cookie, URL encoding or other information transference mechanism, to provide an audio experience that seamlessly transfers the end user from the first service to the second.

Title: Connector for fluid handling systems
Inventor: CAMPAU DANIEL N
IPC: F16L37/098
Filed: 2000-04-05
Abstract: The present invention is directed to a connector for joining fluid flow passegesways in a fluid handling system. The connector may be manually manipulated, without using any tools, to quickly and easily couple or decouple the mating connector components. Those components include a plug having a cylindrical plug wall and a radially extending flange, and a mating socket having a cylindrical socket wall and a pair of diametrically opposed retainers. The retainers each comprise an axially extending flexible lever spaced from the socket wall. The lever is joined to the socket wall at a base or proximal end and has a latch at its free or distal end. The lever is also joined to the socket wall by a fulcrum wall or living hinge positioned intermediate the ends of the lever. A split lock ring is disposed between the socket wall and each retainer and is movable from a position adjacent the base of each retainer to a position remote from the base of each retainer. The latch at the free end of each retainer is engageable with the plug flange to prevent disengagement of the plug and socket when the levers are in their free, unstressed state. However, the levers may be manually deflected or depressed at a flexing portion thereof when the lock ring is positioned adjacent the retainer bases to disengage each latch from the plug flange and thereby permit axial decoupling of the plug and socket.

Abstract: An apparatus, method and system are provided for a hand-off of a communication session in a wireless data network system, in which the communication session has been established previously with a mobile unit through a first base station, a first serving routing node and a gateway routing node utilizing a first addressing context.  The preferred method embodiment includes, when a second base station has been selected for hand-off, first establishing a second addressing context, for the mobile unit, between the gateway routing node and a second serving routing node. The gateway routing node then concurrently routes incoming data packets for the mobile unit to the first serving routing node utilizing the first addressing context and to the second serving routing node utilizing the second addressing context. When the mobile unit has retuned to the second base station, the second base station transmits to the mobile unit current voice communication from the incoming data packets with the second addressing context, and receives any outgoing voice communication from the mobile unit. Following such retuning, the gateway routing node may then cease to route incoming data packets for the mobile unit to the first serving routing node utilizing the first addressing context while continuing to route incoming data packets for the mobile unit to the second serving routing node utilizing the second addressing context.
