Patent number: 7225013Abstract: A method and system predicts changes of physiological/pathological states in a patient, based on sampling, processing and analyzing a plurality of aggregated noisy biomedical signals. A reference database of raw data streams or features is generated by aggregating one or more raw data streams. The features are derived from the raw data streams and represent physiological/pathological states. Each feature consists of biomedical signals of a plurality of patients, wherein several patients have one or more of the physiological/pathological states. A path, which is an individual dynamics, between physiological/pathological states is obtained according to their order of appearance. Then, a prediction of being in physiological/pathological states, or transitions to physiological/pathological states in the patient, is obtained by comparing the individual dynamics with known dynamics, obtained from prior knowledge.Type: GrantFiled: October 3, 2003Date of Patent: May 29, 2007Assignee: Widemed Ltd.Inventors: Amir Geva, Kobi Todros, Baruch Levi, David Solomon, Dan Kerem

Patent number: 7075048Abstract: A method for determining azimuth and elevation angles of a radiation source or other physical objects located anywhere within an cylindrical field of view makes use of an omni-directional imaging system comprising of reflective surfaces, an image sensor and an optional optical filter for filtration of the desired wavelengths. The imaging system is designed to view an omni-directional field of view using a single image sensor and with no need for mechanical scan for coverage of the full field of view. Use of two such systems separated by a known distance, each providing a different reading of azimuth and elevation angle of the same object, enables classic triangulation for determination of the actual location of the object. The invention is designed to enable use of low cost omni-directional imaging systems for location of radiation sources or objects.Type: GrantFiled: March 1, 2005Date of Patent: July 11, 2006Assignee: Wave Group Ltd.Inventors: Ehud Gal, Reuven Eyal, Gil Graisman, Gennadiy Liteyga
