Title: Method and apparatus for a wireless telecommunication system that provides location-based messages
Inventor: CLARK DOUG
IPC: H04W4/021
Filed: 2000-11-02
Abstract: A wireless telecommunication system receives information from a wireless mobile unit and determines that the wireless mobile unit is within a designated region. Information specific to the designated region is received  at a centrally located location-based message server. As the traveler enters th e designated region, the wireless mobile unit then receives information specif ic to the designated region such as information relating to traffic problems or desired locations within the region. Alternatively, a problem is identified and designated as relating to a particular region, and wireless mobile units within the designated region are then identified so that information relating to th e problem can be output thereto. As such, information specific to a region occupied to a traveler is received.

Title: Lubricated high speed fluid cutting jet
Inventor: KATZ JOSEPH
IPC: B24C5/04
Filed: 1998-03-21
Abstract: A high speed fluid jet nozzle made at least in part of a porous material and configured so that the porous part of the nozzle is surrounded at least in pan by a reservoir containing a lubricant fluid. As a cutting fluid passes through the nozzle, lubricant from the reservoir is drawn through the porous material and lubricates the surfaces of the nozzle exposed to the fluid jet. The invention not only resolves the main difficulties of the prior an relating to nozzle wear, it expands the use and applications of high speed fluid jet cutters. By reducing wear of a jet nozzle, it is possible to increase the jet speed and reduce the nozzle diameter even further than the prior art, allowing much higher precision, deeper cutting, and usage on difficult to cut material such as ceramics. The invention thus provides a reliable but yet very simple method for preventing nozzle wear.

Title: A self-resetting child-resistant trigger sprayer
Inventor: PARES MONTANER PEDRO
IPC: A01M7/00
Filed: 2001-02-22
Abstract: A self-resetting child-resistant trigger sprayer having a lock slidingly mounted on the trigger lever for locking the trigger sprayer. The lock has a pair of extensions, a biasing means and a projection that all extend away from the main portion of the body of the lock. The extensions engage a portion of the trigger sprayer and the biasing means provide a restoring force that enables the trigger sprayer to be self-resetting. The projection is capable of being moved by the operator of the sprayer along the trigger lever. When in a raised position, the extensions disengage from a portion of the body of the sprayer placing the sprayer in an unlocked position. However, when the projection is released, the extensions engage a portion of the piston cylinder preventing the piston cylinder from moving and the biasing means automatically force the lock into a lower, locked position on the trigger lever thus rendering the sprayer self-resetting and child-resistant.

Title: Anti-reflux esophageal prosthesis
Inventor: DUA KULWINDER S
IPC: A61F2/04
Filed: 1999-08-31
Abstract: An esophageal prosthesis (10) for preventing reflux of gastric fluids through the oesophagus. The esophageal prosthesis process includes a tubular frame (11) with a sleeve (13) disposed around and longitudinally along the tubular frame as well as extending from the distal end (14) of the frame. The lower portion (28) of the sleeve has a readily collapsible lumen (15) that forms a one-way valve for preventing the reflux of gastric fluids in an antegrade manner through the esophagus. Fluids however readily flow throuhgh the sleeve in a antegrade direction. In response to a pressurebuild up in the stomach of a patient wanting to belch or vomit, the lower portion of the sleeve inverts through the passage (12) of the tubular frame, thereby relieving the pressure build up or voiding the patient's stomach. The tubular frame includes a plurality (19) of self-expanding zig-zag wire stents (20, 21, and 23) that maintain the patency of the esophagus and, in particular, the lower esophageal sphincter and any tumor that is causing stricture of the esophagus.

Patent CA-2340302-A1 (CA)
Inventor: BUCKSBEE JAMES H
IPC: B60K5/12
Filed: 2001-03-08
Abstract: A mount for isolating a vibrating member from its support. In several embodiments an elastomeric element is made up of four components that are preferably bonded to the inclined outer surface of an inner member and the inclined inner surface of an outer member. One of the inner and outer members is bifurcated and drawing the two halves into mating engagement results in the elastomeric components being preloaded simultaneously in compression and shear. The elastomeric element is preferably formed with portions which snub movement in each of three orthogonal directions. The dimensions of the pair of elastomeric components above or below the vibrating member may be different than the other pair since the greater compression strain on one pair of components to maintain maximum design stress levels. In another embodiment, the inner and outer members are each a single component with four elastomeric elements bonded between metal plates and preloaded between the inner and outer surfaces of the members in an X-like configuration. In still another embodiment of the X-configuration the metal plates have turned-out ends for gripping the members. The inclined surfaces have grooves for preventing, in concert with the turned-out ends, displacement and complete dislodgment of the inner member.      The base of the outer member alternatively has extended sides for reducing bending stresses in the bolts which fasten it to the support.
Patent CA-2341577-A1 (CA)
Inventor: LEE YOUNG-HWAN
IPC: H04J13/00
Filed: 2000-07-08
Abstract: A data rate detecting device detects a data rate for a received signal based on a variation of the energy for the respective received signals between the two adjacent intervals upon failure to receive information about the data rate, and performs channel decoding of the detected data rate information. First, the data rate detecting device divides an interval defined as between a lowest and highest one of a plurality of given data rates into m discriminating intervals. Then, the device calculates a difference between an average energy of received signals up to an i'th discriminating interval and an average energy of received signals for an (i+1)'th discriminating interval, wherein i is an integer is less than m. If the difference between the average energies is greater than or equal to a threshold value, the device determines that the received signal in the (i+1)'th discriminating interval is transmitted at a data rate corresponding to the i'th discriminating interval.

From there it is steered through an eye of a moveable sledge which a round steering pipe is fastened. The steering pipe being equally thick as the oblong hole (main eye) on the stance of the device. The steering pipe goes inside the main eye. Then the snood material is steered through a swivel eye and a hook eye located directly in front of the steering pipe inside the main eye. A thrusting pin holds the snood material while the necessary step is taken to fasten the snood material on the hook. The snood material is then fastened to the swivel and the snood material is cut from the snood material roll. Then a fastened snood is both on the hook and the swivel. This device is both used on land as on sea.
