Title: Bone fracture prevention garment and method
Inventor: HAYES WILSON C
IPC: A61F13/00
Filed: 1993-11-18
Granted: 2007-01-09
Abstract: A garment (2), in one embodiment of the invention, reduces the risk of bone fracture of a human or animal subject due to impact forces on a vulnerable region having a bone part near the skin surface when the vulnerable region is proximate to a soft tissue region lacking a bone part near the skin surface. The garment (2) has an arrangement for shunting a substantial portion of the impact energy from the vulnerable region to the soft tissue region where such energy may be safely absorbed and/or dissipated. In a further embodiment, there is utilized a dilatent material that is relatively stiff near the time of impact and relatively fluid at other times. Related methods are also provided.

Title: Database dependency resolution method and system for identifying related data files
Inventor: GROSSE ERIC
IPC: G06F17/30
Filed: 1995-09-20
Granted: 2000-04-04
Abstract: A method and system for displaying names of data files in a collection of data files represented by a corresponding symbol. According to one embodiment of the present invention, a user may display a listing of subroutine library files required to execute a particular subroutine.      In such an embodiment, the user may enter the subroutine name as the symbol of interest and the system would display the library file containing that subroutine as well as those data files that contain subroutines called by that subroutine of interest. The present invention uses a transitive closure technique to traverse a data structure generated from a database and retrieve the data file list.      The transitive closure technique enables the use of a compact database that contains only the data file names, corresponding symbol names, and symbol names of only data files for each data file that are directly related to that data file.

Title: Vehicle identification system for electric toll collection system
Inventor: KUWAHARA YOSHIHIKO
IPC: G01S7/51
Filed: 1997-04-14
Granted: 2001-01-23
Abstract: A plurality of antennas receives radio wave transmitted from a vehicle which comes in a toll collection area.  Each antenna has at least three antenna elements, and the antennas are disposed in the horizontal direction and vertical direction.  The signal analyzer analyzes the ID signal included in the received radio wave to identify the vehicle.          The direction detector measures the direction of arrival (DOA) of radio wave received by two antennas selected by the antenna selector by way of two-dimensional interferometry principle in terms of the directional angle and depression angle.  The location detector calculates the location of the vehicle in the horizontal direction and the height in the vertical direction of the vehicle as a location information based on the DOA of the radio wave measured by the direction detector.          The vehicle tracking unit generates the locus data of the vehicle based on the location information calculated by the location detector and the information for identifying the vehicle analyzed by the signal analyzer.  On the other hand, the video camera takes a picture of the vehicle which comes in the toll collection area to obtain the picture data.  The data correlation unit judges whether the vehicle is a violator vehicle by correlating the picture data and locus data.  The controller registers the locus data and picture data of the vehicle if the vehicle is a violator vehicle.  On the other hand, the controller collects a prescribed toll from the vehicle if the vehicle is not a violator vehicle.

Title: Dimensionally stable tufted carpet
Inventor: IRWIN DONALD A SR
IPC: B32B5/00
Filed: 1997-10-15
Granted: 2003-12-30
Abstract: A carpet is tufted with a two-part primary backing. The upper, or face, backing is a conventional woven or non-woven polypropylene, and the lower, or back, backing is a stronger, open weave fabric.  The tufts of yarn are sewn through both parts of the primary backing, which holds the parts together, and causes some of the back stitches to protrude for better coating with adhesive.  The resulting carpet may be fully back coated, and may have a secondary backing adhered thereto.  The lower backing prevents elongation, stretching and shrinking of the carpet during manufacture and subsequent processing.

Patent CA-2245146-C (CA)
Inventor: SHIELDS GLEN DENNIS
IPC: C09D11/10
Filed: 1997-01-31
Granted: 2003-04-08
Abstract: This invention provides the preparation of water-dispersible polyester/acrylic hybrids via a two-stage emulsion polymerization process. For example, methacrylic acid and/or 2-hydroxyethyl methacrylate are copolymerized with styrene/acrylic monomers to yield a relatively hydrophilic and hydro-plasticized first stage. Subsequent additions of hydrophobic monomers to this first stage "seed" result in an inversion of the latex such that the more hydrophilic first stage is at the particle surface. This results not only in improved stability of the resulting latex without the use of additional surfactants, as evidenced by the production of reduced amounts of coagulum, while it also offers relatively low minimum filming temperatures due to the hydroplasticization of the shell of the particle. Furthermore, the use of the water-dispersible polyester results in extremely fine latex particle sizes which can significantly enhance coating properties such as film gloss and clarity.
