Title: High capacity feller head
Inventor: KURELEK JOHN
IPC: A01G23/081
Filed: 1995-02-22
Abstract: The felling and bunching head for severing and grouping trees has a shear or saw or the like for severing trees, and an accumulation area for accumulating severed trees, extending rearwardly from the shear or saw, substantially outwardly and away from a centerline of said head. Taker and tucker arms are pivotally mounted to pivot towards and away from the accumulation area. The taker and tucker arms are mounted via pivotal connections located substantially outwardly from the shear or saw on the opposite side of the centerline from the accumulation area. The taker and tucker arms have generally similar geometries facing the accumulation area, as viewed from above, thereby presenting generally similar geometries to trees in the accumulation area, thereby minimizing jostling of the trees when they are alternately held in the accumulation area by the taker and tucker arms.

Title: Method, test element and kit for semi-quantitative detection of target nucleic acid
Inventor: BERGMEYER LYNN
IPC: C12P19/34
Filed: 1995-03-30
Abstract: A target nucleic acid can be detected in a semi-quantitative fashion by passing it over detection deposits in a test element. The detection deposits include particles affixed to the test element, some of which particles have capture probe attached thereto, and other particles having no capture probe. The deposits have varying amounts of capture probe so that the signal obtained when the target nucleic acid is captured thereon can be semi-quantitatively correlated to the amount of target nucleic acid in the specimen. This method of detection can be used in nucleic acid hybridization assays or following amplification methods, including polymerase chain reaction.

Title: Syntax parser for a video decompression processor
Inventor: HOOGENBOOM CHRIS
IPC: H04N7/50
Filed: 1995-10-04
Abstract: A video syntax parser is provided for a video decompression processor.  A compressed bitstream is examined until a start code is located.  The start code is decoded to enable a particular parser state corresponding thereto to be initiated.  The parser state is communicated to a plurality of subsystems of the video decompression processor.  Each subsystem monitors the parser state to determine which parsed data following the start code, if any, is intended for that subsystem.  The subsystem then retrieves the parsed data it requires via a data bus which receives the parsed data from the parser.

Title: Semantic object modeling system for creating relational database schemas
Inventor: KROENKE DAVID M
IPC: G06F19/00
Filed: 1994-09-13
Abstract: A computer-based system for allowing a user to create a relational database schema. The system allows a user to create a semantic object data model of the database schema. The semantic object data model is defined by one or more semantic objects, each of which includes one or more attributes that describe a characteristic of the semantic objects. The attributes are defined as being either simple value attributes that describe a single characteristic of the semantic object; group attributes that include one or more member attributes that collectively describe a characteristic of the semantic object; formula attributes that set forth a computation that describes a characteristic of a semantic object; or object link attributes that define a relationship between two or more semantic objects. Once the semantic object data model is created, the system validates the semantic objects to ensure no modeling errors have been made and transforms the semantic objects and their included attributes into a plurality of relational database tables that will store data as defined by the semantic object data model.
Patent CA-2181455-A1 (CA)
Title: Device executing intervisibility calculation
Inventor: KODET THOMAS A
IPC: G06T15/06
Filed: 1995-01-17
Abstract: A device executing intervisibility calculation includes a     mechanism executing a radial spoke scan pattern      where individual radials are traversed      beginning at a threat installation and extending     outward along a radial  to    a distance    corresponding to threat range capability. Intervisibility calculation is simplified to allow implementation        in a simple, dedicated hardware engine to provide rapid execution time while     ensuring accurate intervisibility results. The intervisibility engine includes lookup tables to provide precalculated data and advantageously avoids divide operations whereby the intervisibility calculation may be executed by use of a series of adds, substracts, and multiplies relative to intervisibility data developed while traversing a given radial. The engine calculates a slope for each data post visited in traversing a radial, and identifies a data post as being visible when its associated slope is greater than a previously encountered greatest magnitude slope. The engine stores in a digital terrain elevation database an intervisibility ground reference value representing a magnitude of vertical clearance between a given data post elevation and a threat detection envelope thereabove. The execution time provided by the intervisibility engine of the present invention is sufficiently fast to allow dynamic, in-flight calculation to aid in intervisibility calculation relative to a just discovered or just moved threat installation. The digital terrain elevation data may be referenced to display or select routes relative to known or detected threat installations.

Title: Pure
Inventor: LUSSIER PIERRE
IPC: A23K50/40
Filed: 1997-02-20
Abstract: In all methods of reducing feline urine odor when excreted, it is known that strong chemical products are used to mask the urine scent once it is excreted. There exists chemical urine odor removers, scented litters and feline air fresheners that all claim to reduce domestic feline urine odor. In this invention, the method ofodor reduction consists of an acetic acid solution in a water solvent which is ingested and replaces a domestic feline's regular drinking water. The present invention reduces the decomposition of urea by introducing into the urinary system a weak acid solution. This in turn reduces the amount of ammonium carbonate, a by-product of urea breakdown, which also reduces the amount of ammonia excreted in the urine to finally reduce domestic feline urine odor. Contrary to existing methods, this invention prevents the odor, of excreted urine, from occurring as opposed to masking the odor of urine once it has been excretedby the domestic feline.
