Patent CA-2496440-A1 (CA)
Title: Height-adjustable pipe pick-up and laydown machine
Inventor: THOMPSON CARROLL R
IPC: E21B19/15
Filed: 2003-05-02
Abstract: The present invention provides a pipe-handling machine (100) for picking up and laying down pipe, such as at a rig site. The machine first comprises three elongated and nested truss members. First, a trestle (200) is provided;  second, a trough carrier (300) is received within the trestle; and third, a trough (400) is slidably received within the trough carrier. The machine next comprises an inclined ramp (500). A lower end of the ramp is pivotally connected to the trestle, while an upper end of the ramp extends upward to the rig floor. The length of the ramp is adjustable to accommodate rig floors of varying heights. A trestle transport mechanism (550) selectively moves a front end of the trestle upwards along the ramp, thereby delivering a joint of pipe to the rig floor. The trough may optionally be moved along the trough carrier and out over the rig floor to aid in delivery. Features (310) may optionally be incorporated to reduce the angle of approach of the joint of pipe relative to the rig floor after the trestle transport mechanism is actuated.

Title: Temporal transition network protocol in a mobile ad hoc network
Inventor: KENNEDY ROBERT A
IPC: H04L12/56
Filed: 2003-09-11
Abstract: The mobile ad hoc network includes a plurality of wireless mobile nodes (12) and a plurality of wireless communication links (14) connecting the nodes together. A method for managing and controlling the discovery and maintenance of routes in the network includes transmitting beacon signals from each mobile node, determining a node or group condition at each mobile node, and varying the beacon signals based upon the determined node/group condition. Route tables are built and updated at each mobile node with a first one of proactive and reactive route discovery processes to define routes in the network. The beacon signals are received and node/group condition information is stored at each node. Route stability over time is predicted based upon the node/group condition information, and when predicted route stability reaches a first transition parameter the method switches to a second one of the proactive and reactive route discovery processes.

Title: Artificial intelligence for analyzing hypothetical models
Inventor: SCHNEIDER LUKE V
IPC: G06F19/00
Filed: 2003-10-01
Abstract: Biology models of biochemical systems have proven to be powerful conceptual tools for the analysis of biological data. Biological data is unique in that it exists mostly in the differential display format. The present invention (Fig. 1) uses artificial intelligence (AI) to synthesize bioinformatic data (unit operations) for building and analyzing models of underlying physiologi es (hypothetical mathematical models). In addition to AI methods, the invention describes the use of differential equations [e.g. the Michaelis-Menton kinetics equation, d/dt(Substrate[t])=- Enzyme[t]Substrate[t]/(Km+Substrate[t])] and linear algebra (i.e. the linear differential equation of the Michaelis-Menton kinetics equation and its Laplace transform) to recast the models into another mathematical domain. Th e direct use of differential display data formats for model testing provides more complete alternatives for modeling physiological and other complex systems towards a global solution.

Title: System and method for delivery of information based on web page content
Inventor: MARTIN ANTHONY G
IPC: G06Q30/02
Filed: 2003-10-01
Abstract: The present invention provides a system for determining when to present information to a user based on web page content. The system includes a retriever engine, a display engine, and a parser engine. The retriever engine transmits a domain to a server. In response, the server transmits information to be displayed and in-context rules, which are received by the retriever engine. The parser engine parses the HTML source code of a web page and decides whether to display the information based on the in-context rules. If it is determined that the information should be displayed, the display engine displays the information.

Title: Bicyclic carbohydrate compounds useful in the treatment of infections caused by flaviviridae sp., such as hepatitis c and bovine viral diarrhea viruses
Inventor: PEYS ERIC
IPC: A61K31/70
Filed: 2003-12-22
Abstract: We describe the use of bicyclic carbohydrates for the treatment of hepatitis C virus infections. Different bicyclic carbohydrates were tested in vitro against DNA-viruses, retroviruses and Flaviviridae sp., an important family of human and animal RNA pathogens. Significant activity was observed against th e bovine viral diarrhea virus (BVDV). As pestiviruses, such as BVDV, share man y similarities with hepatitis C virus (HCV), the bicyclic carbohydrates in general and the preferred bicyclic carbohydrates more specifically are expected to be a treatment for hepatitis C viral infections.

Title: Method for the post-injection of hydrocarbon-, alcohol- and/or reducing-agent-type regeneration solution (e.g. diesel fuel and/or urea and/or ammoniacal solution) for the regeneration of diesel engine exhaust gas filtration systems
Inventor: FAYARD JEAN-CLAUDE
IPC: F01N13/02
Filed: 2003-12-23
Abstract: The invention relates to a post-injection method for the regeneration of a device used to filter exhaust gases produced by a diesel engine. The inventive method consists essentially in injecting fully-pulverised hydrocarbon-, alcohol- and/or reducing-agent-type regeneration solution (e.g. diesel fuel and/or urea and/or ammoniacal solution) upstream of the oxidation catalyst (14) in order to increase the temperature of the exhaust gases upon detection of the clogging of the filter with particles. Using temperature (2) and pressure (3) sensors which are disposed upstream of the filtration device, the computer (8) controls the injection of the regeneration solution from the electromagnetic injector (9), said regeneration solution being directed through a capillary (12) into the exhaust pipe (1) at a point which is located at a good distance from the aforementioned injector, upstream of the catalyst (5), in order to be finely pulverised by the air.

Title: Copying copy protected optical discs
Inventor: DOYLE WILLIAM HENRY CHRISTOPHER
IPC: G11B20/00
Filed: 2004-06-11
Abstract: To copy a copy protected DVD (32), and thereby subvert the copy prot-ection technique, a DVD drive (50) is controlled by a disc copying program (54) to access data at a level other than that at the user data level. For example, if it is the data frame (44) which is read, the DVD drive (50) is controlled to write a data frame (12) to a copy disc (52). During the copying process, the program (54) may be arranged to remove sector IDs and error detection codes from the read data frames (44) and to generate new sector IDs and appropriate ID error detection codes for the data frames (12) to be written to the copy disc (52). This circumvents any copy protection which has been incorporated in the identification data in a data frame of the original disc (52).

For non-trivial objects, or those with complicated two or three dimensional forms, it may be difficult t o present information in a manner that is simple for a user to understand. The local distance to a surface of interest, such as the surface of the defined object, or to a desired position, the local penetration distance of the surface of interest, or haptic repulsion force, often provides the most usef ul information for augmenting the interaction of the user with the image guided surgery system. The scalar value of the local distance may be conveyed to th e user by visual, audio, tactile, haptic, or other means.
