Patent number: 8326662Abstract: Example embodiments provide program products, systems, and associated methods of presenting a seller with a graphical representation of demand for a potential product listing so that the seller can intelligently price and position the product. A website server associated with a website of product listings captures in a database product preference criteria for a consumer, including, for example, price information. The website server aggregates the captured product preference criteria for a plurality of consumers and determines an imputed consumer demand for a potential product listing. The website server displays on a display device associated with a computer of a seller a multi-dimensional graph of demand for the potential product listing so that the seller can gauge market demand prior to listing a product for sale. Embodiments further include two-dimensional graphs plotting demand versus price, contour lines for the demand imposed on pricing graphs, and color-coded demand heat maps.Type: GrantFiled: June 18, 2009Date of Patent: December 4, 2012Assignee: Overstock.com, Inc.Inventors: Patrick Michael Byrne, Geoffrey Russell Atkinson

Patent number: RE43187Abstract: A method of measuring an analyte concentration in body fluid. The method includes the use of an analyte measuring device that has an analyte sensing element with a sharpened distal end and further has an indicating electrode covered by an absorbent layer. Also, an electric power, data processing and display device is adapted to mate to and activate the analyte sensing element by applying electric power to it and adapted to receive the raw analyte measurement and to compute and display a refined analyte measurement from the raw analyte measurement. The analyte sensing element is introduced into the animal body, thereby placing the absorbent layer into contact with the body fluid. The absorbent layer becomes saturated with body fluid and the analyte sensing element is removed from the body and is activated to form a raw analyte measurement. Which which is used to form and display a refined analyte measurement.Type: GrantFiled: October 9, 2008Date of Patent: February 14, 2012Assignee: iSense CorporationInventors: Geoffrey A. Russell, W.
