Publication number: 20080125977Abstract: Quantum simulation methods are used to encode the quantum response of a molecular system so as to improve the sensitivity for detection of a target material, while rejecting background. The perturbation and response information may be used to discover the system function of a quantum system, or more generally, of a complex system, such as a physiological system. The approach may be applied to medical non-invasive, real-time, continuous molecular detection and quantification techniques through coherent Raman spectroscopy to enable a significantly more attractive course of therapy than existing protocols.Type: ApplicationFiled: October 29, 2007Publication date: May 29, 2008Applicant: Aretais, Inc.Inventors: Patrick A. ANQUETIL, Ian W. HUNTER, Serge LAFONTAINE, Shyamal SOMAROO, Ching-Hua Tseng

Publication number: 20080117416Abstract: System and methods are provided to perform non-invasive, real-time, continuous molecular detection and quantification of molecular species in a sample or animal subject using Raman spectroscopy. Such systems and methods may be applied to identify and quantify molecular species found in the body, which may be useful for prenatal diagnosis, detecting deep skin infections, performing cerebral spinal fluid assessment, measuring arterial blood gases, blood glucose, cardiac biomarkers, creatinine flow rates. The non-invasive, quantification of such molecular species continuously in real time enables a significantly more attractive course of therapy than existing protocols.Type: ApplicationFiled: October 29, 2007Publication date: May 22, 2008Inventors: Ian W. Hunter, Shyamal Somaroo, Serge Lafontaine, Patrick A. Anquetil, Ching-Hua Tseng

Patent number: 6967658Abstract: A method and apparatus is disclosed in which one or more standard faces are transformed into a target face so as to allow expressions corresponding to the standard face(s) to be used as animation vectors by the target face. In particular, a non-linear morphing transformation function is determined between the standard face(s) and the target face. The target face animation vectors are a function of the morphing transformation function and the animation vectors of the standard face(s).Type: GrantFiled: June 22, 2001Date of Patent: November 22, 2005Assignee: Auckland UniServices LimitedInventors: Peter J. Hunter, Poul F. Nielsen, David Bullivant, Mark Sagar, Paul Charette, Serge LaFontaine

Patent number: 6486881Abstract: An image processing system in which the vertices of an object contained within an image are analyzed using a singular value decomposition (SVD) method is disclosed. The use of the SVD allows the original vertices data to be reduced through filtering or truncating the singular values associated with the image. In addition, the reduced vertices data and the associated SVD matrices allows for efficiently streaming video data.Type: GrantFiled: June 15, 2001Date of Patent: November 26, 2002Assignees: Lifef/x Networks, Inc., Auckland UniServices LimitedInventors: Peter J.

Publication number: 20020007276Abstract: A system and method for enabling the use of photo-realistic, three-dimensional virtual representatives in a variety of communications settings is disclosed. A first module is employed for selecting a virtual representative to be used for communicating with a user, for defining text to be voiced by the selected virtual representative, and for inserting emotion cues into that text. A second module responds to data from the first module by generating an image of the virtual representative, then controls changes in the image in accordance with the text to be voiced and the corresponding emotion cues. A third module is employed for defining virtual representatives and the response of virtual representatives to emotion cues associated with text to be voiced. The modularity of the presently disclosed invention lends itself to the integration into a variety of settings, including Web pages, email and PC games.Type: ApplicationFiled: May 1, 2001Publication date: January 17, 2002Inventors: Michael S. Rosenblatt, Lucille S. Salhany, Richard Guttendorf, Serge LaFontaine
