Title: Trenching method and apparatus
Inventor: KELLY KEITH RICHARD
IPC: E02F5/06
Filed: 2001-11-13
Granted: 2010-04-13
Abstract: Trenching apparatus comprises a cutting device (23), preferably an endless chain cutter, mounted on a prime mover (21) for positioning the cutting device in a trench (18) with the prime mover movable on the ground surface (22) above the level of the trench. Where the cutting device is a chain cutter, the boom projects forwardly and downwardly relative to the direction of cutting the trench, and drive means are arranged to drive the chain in a direction to carry the cutting elements upwardly around the distal end of the boom and rearwardly along the upper run (30) of the endless chain cutter (23). In operation the distal end of the chain cutter (23) is positioned against the end face of the trench at the bottom of the trench (18); the prime mover (21) moves the chain cutter forwardly in the trench while operating the chain cutter, so as to produce an undercut (55) in the end face (54) of the trench; and the lifting means (25) lifts the cutting device (23) upwardly from the undercut through the material of the end face so as to cut material from the end face of the trench.

Title: Methods and apparatus for providing context and experience sensitive help in voice applications
Inventor: COOPER ROBERT S
IPC: G06F9/44
Filed: 2005-01-18
Granted: 2009-06-09
Abstract: Systems and techniques for improved user prompting in the event of voice recognition failures. A system according to one aspect of the invention includes a central server hosting various modules employing voice recognition in order to interpret user inputs. When a module fails to recognize an input, it invokes a help application that selects an appropriate help prompt. The help application has access to user information including information indicating the user's experience with each function of each module. The help application receives notification of the module and function being used when the unrecognized input was received and examines the user information to determine the user's experience with the module and function. The help application categorizes a user as belonging to an experience category, such as novice, intermediate and expert based on the user's experience with the function and selects a help prompt associated with the user's experience with the function.

Title: Process for determining competing cause event probability and/or system availability during the simultaneous occurrence of multiple events
Inventor: TAN JONATHAN SAMUEL
IPC: G06F17/18
Filed: 2003-10-03
Granted: 2011-09-27
Abstract: A method for determining the probability of observing an event. The event may occur either alone or in combination with one or more other events. The method may be non-combinatorial in that it does not require a separate calculation for each simultaneously occurring event, thereby significantly reducing computation time for complex systems having multiple events. Further, the method may be numerically reversed to calculate the probability of an event occurring based upon the number of observations. The method is particularly useful for predicting availability, component failure, or the possibility of a false start in production systems.

Title: Brake actuator for a towed vehicle
Inventor: SAVARIA PIERRE
IPC: B60D1/167
Filed: 2005-04-06
Granted: 2010-06-29
Abstract: A brake actuator is mounted on a towed vehicle. The towed vehicle's own brake pedal actuates the brakes of the towed vehicle and the brake pedal is actuated by a cable mechanically and releasably attached to the brake pedal. The cable is itself fixedly attached to a cable attachment means which is part of a body. In turn, the body is connected to the towing vehicle through a towing implement in the farm of a tow bar. When the towing vehicle decelerates, the inertia of the towed vehicle causes the mounting bars to apply pressure against a lower part of the body, this is countered by the tow bar, connected on an upper part of the body, which has for effect to make the body rotate around its axis which is situated in a middle part of the body. This results in the lower part being moved forward which pulls on the cable, which in turn pulls on the brake pedal.
