Patent CA-2276975-A1 (CA)
Inventor: SCHLICHTIG ROGER J
IPC: G01S13/931
Filed: 1999-07-06
Abstract: A method and apparatus for detecting the presence of objects in a vehicle operator's blind spots. The apparatus comprises a side-facing Doppler radar system using continuous wave (CW) transmission with frequency modulation (FM) operation from a frequency modulation switching technique. The radar system determines the presence, range and closing rate of detected targets. The radar system detects targets even when operated in adverse weather conditions and will not generate false warnings due to rain clutter caused by wet roads and other wet surroundings. The radar system uses ranging techniques to reject false targets that are detected outside of a predetermined target detection zone. In accordance with the present invention, the radar system indicates that a target is detected if and only if any part of the target is within the detection zone and it: (1) remains in front of the antenna for at least TH1 seconds; (2) is at a range between Rangemin and Rangemax; and (3) is moving faster than Closing-Speedmin relative to the antenna. By rejecting targets that are closer than Rangemin feet to the antenna, false alarms due to rain clutter are dramatically reduced. Also, by rejecting targets that are further than Rangemax feet from the antenna, the radar system reduces false alarms caused by wet foliage and other wet "non-road" surroundings. In one embodiment, the radar system uses a patch array antenna oriented into a diamond-shape configuration to effectively create a natural linear amplitude taper that aids in rejecting clutter caused by wet road surfaces.

Title: High pressure solenoid
Inventor: CARTER STEPHEN A
IPC: F16K31/06
Filed: 1999-07-14
Abstract: An improved electrically operated pilot-type, "instant-on" solenoid assembly for near-instantaneous control over the flow of compressed gas. The assembly may be applied in fuel systems for propulsion in vehicles using gaseous fuel. It includes a housing with inlet and outlet passages connected to a primary chamber where a primary piston is slidably mounted, a secondary chamber having a secondary piston slidably mounted within the chamber, a solenoid to produce translational movement of the pilot piston, and passageways linking the various components. When the solenoid is energized, the pilot piston is moved to permit fluid to flow from the primary to the pilot chamber, producing an increase in the differential pressure in the regions of the primary chamber. The differential pressure then forces the primary piston to move, exposing the outlet to fluid flow from the gas inlet.

Title: Recombination of polynucleotide sequences using random or defined primers
Inventor: ZHAO HUIMIN
IPC: C12Q1/68
Filed: 1998-03-25
Abstract: A method for in vitro mutagenesis and recombination of polynucleodde sequences based on polymerase-catalyzed extension of primer oligonucleotides is disclosed. The method involves priming template polynucleotide(s) with random-sequences or defined-sequence primers to generate a pool of short DNA fragments with a low level of point mutations. The DNA fragments are subjected to denaturization followed by annealing and further enzyme-catalyzed DNA polymerization. This procedure is repeated a sufficient number of times to produce full-length genes which comprise mutants of the original template polynucleotides. These genes can be further amplified by the polymerase chain reaction and cloned into a vector for expression of the encoded proteins.

Title: Hinge mechanism
Inventor: TORCATO JOSEPH
IPC: E06B3/38
Filed: 1999-10-13
Abstract: A hinge mechanism is disclosed which allows for pivotal attachment of a moveable member to a fixed frame member defining a linear edge of an opening. Such pivotal attachment allows for movement of the moveable member relative to the fixed frame member between a closed position, in which the moveable member is positioned substantially within the opening, and an open position, about a pivot axis aligned parallel and adjacent to the linear edge and positioned in offstanding spaced relation thereto. The hinge mechanism comprises a fixed hinge component and a moveable hinge component. The fixed hinge component comprises a base portion, mountable upon the fixed frame member, a longitudinally extending pin portion and a support arm extending between said portions in connecting relation. The pin portion has a substantially cylindrical outer surface and is terminally positioned on the support arm, a portion of said outer surface defining a first bearing surface. The moveable hinge component has a swinging portion, adapted for attachment to the moveable member, and a pivoting portion, having a concave inner second bearing surface concentric with the first bearing surface and being operatively mounted about said first bearing surface so as to provide for said pivotal movement. A  first longitudinally extending shoulder projecting from the moveable hinge component and a second longitudinally extending shoulder projecting from the fixed hinge component, are arranged such that, upon the moveable hinge component pivoting to the open position, the first shoulder impinges upon the second shoulder to arrest further opening rotation.
