Patent number: 6882748Abstract: A method and apparatus for image texture analysis in which the image is mapped into a first set of binary representation by a monotonically varying operator, such as a threshold operator. Each binary representation in the first set of binary representations is mapped to a further set of binary representations using a second monotonically varying operator, such as a spatial operator. The result of the two mappings is a matrix of binary image representations. Each binary image representation is allocated a scalar value to form an array of scalar values which may be analysed to identify defined texture characteristics.Type: GrantFiled: August 31, 2001Date of Patent: April 19, 2005Assignees: University of Adelaide, RLM Systems Pty. Ltd., Commonwealth of Australia, University of Melbourne, University of Queensland, Compaq Computer Australia Pty.

Patent number: 6241881Abstract: A stormwater pollution separator and filter apparatus to be fitted inline in a stormwater conduit. The apparatus has an inlet (1) receiving stormwater and leading through an inlet aperture (3) to a separation chamber (4) which then leads to a filtration chamber (5) which is positioned below the inlet aperture (3). A riser (6) leads from the filtration chamber (5) to an outlet (7) which is connected back to the stormwater conduit (3). The inlet opening is connected tangentially into the separation chamber (4) to create, in use, a swirl action in the separation chamber (4) by reason of the flow of the stormwater. The separation chamber (4) is positioned vertically above the filtration chamber (5), and the filtration chamber (5) has one or more filtration baskets (9) positioned in the filtration chamber (5) to receive substantially all the flow of stormwater from the separation chamber (4), the baskets (9) are spaced apart from a wall (10) defining a periphery of the filtration chamber (5).Type: GrantFiled: May 11, 2000Date of Patent: June 5, 2001Assignee: University of South AustraliaInventor: David Pezzaniti

Patent number: 6046293Abstract: A process for manufacturing high molecular weight, alternating polysiloxane copolymers, by solid-liquid phase, nonaqueous, interfacial polymerization. The copolymers consist of alternating siloxane repeating units of the (AB).sub.m type, such as diphenylsiloxane units and dimethylsiloxane units, alternately polymerized together to form the copolymer. The solid-liquid phase interfacial polymerization process is fast, proceeds smoothly at room temperature, and is not reversible, i.e., no cyclic siloxane species are generated. The resulting polysiloxanes can be formed into thermoplastic elastomers which are suitable for use as sealants, fillers, and films.Type: GrantFiled: December 1, 1998Date of Patent: April 4, 2000Assignees: University of South Australia, Dow Corning CorporationInventors: Stephen Ross Clarke, Daniel Graiver, Janis Gunars Matisons, Michael James Owen

Patent number: 6017738Abstract: A method for detecting a target nucleic acid sequence comprises: (a) providing a first primer hybridizing to the target nucleic acid sequence, wherein the primer is immobilized on an immobile solid phase support by a direct chemical linkage between the primer and the solid phase support, wherein the solid phase support forms a part of or is insertable into a container for a sample to be tested, (b) providing a second primer hybridizing to the target nucleic acid sequence in the opposite direction, wherein the second primer is labelled with a detectable label, (c) reacting the first and second primers with a sample containing nucleic acid sequences under conditions which allow amplification of the nucleic acid sequences that hybridize to the first and second primers in the container for the sample, and (d) detecting the presence of bound second primer. Alternatively, the label on the second primer can be attached or incorporated either during or after the amplification process.Type: GrantFiled: December 9, 1996Date of Patent: January 25, 2000Assignees: Adelaide Children's Hospital, University of South AustraliaInventors: Charles Phillip Morris, Raymond John Harris
