Publication number: 20200356753Abstract: A total internal reflection based imaging system may include a light transmitting member having an imaging surface. A pressure sensitive membrane may be arranged on the imaging surface. The pressure sensitive membrane may include a top surface, a bottom surface, and an elastic deformable film forming at least a portion of the top surface. The imaging system may include a textured surface disposed between the pressure sensitive membrane and the imaging surface. An application of pressure on the top surface may deform the deformable film to reduce a distance between the deformable film and the imaging surface. A light source may be configured to emit a light towards the imaging surface such that reduced total internal reflection of the light occurs where the bottom surface of the pressure sensitive membrane contacts the imaging surface. A sensor may be configured to capture the light reflected from the imaging surface.Type: ApplicationFiled: July 27, 2020Publication date: November 12, 2020Applicant: Identification International, Inc.Inventors: Bryan D.

Publication number: 20180330136Abstract: A representation of variations in elevation of friction ridges in a friction ridge pattern of a subject may be generated. A sequence of images captured over a time period may be obtained. Individual images in the sequence of images may indicate areas of engagement between an imaging surface and the friction ridge pattern of the subject when the individual images are captured. Temporal information may be obtained for the individual images. The temporal information for the individual images may be used to aggregate the individual images in the sequence of images into an aggregated representation of the friction ridge pattern. The aggregation may be accomplished such that the aggregated representation depicts the areas of engagement of the friction ridge pattern with the imaging surface at different elevations of the friction ridge pattern.Type: ApplicationFiled: July 23, 2018Publication date: November 15, 2018Inventors: Richard K.

Publication number: 20040219537Abstract: The present invention discloses a method, device, and kit to non-invasively sample epidermal cells of a test subject while ensuring the collection of a large enough quantity of cells for subsequent biological testing. In particular, the method obtains human, or other living creature's, nucleic acid or other biological component for cytological or diagnostic testing and/or genetic analysis. The method takes the sample of the epidermis by means of an abrading surface which scrapes off and retains cell samples for subsequent characterization. The abrading surface could be single use, in a sealed container, where the sample can be returned without contamination. These nucleic acids can be either eluted or resolubilized off, or otherwise released after collection or storage, in a manner that enables them to be amplified by conventional amplification methods such as polymerase chain reaction.Type: ApplicationFiled: May 2, 2003Publication date: November 4, 2004Inventors: Richard K. Fenrich, Matthew Rarick, Susannah Wurgler-Murphy, David R. Comeau

System for recognizing handwritten character strings containing overlapping and/or broken characters
Patent number: 5321768Abstract: A system (method and apparatus) for handwritten character recognition recognizes characters within strings of text despite the presence of overlapping or disjointed characters. A string is segmented into discrete characters by removing noise and punctuation, joining the disconnected components of characters and splitting probable overlapping characters. After joining and splitting (as required), character recognition is performed to recognize characters in the string. Recognized characters are removed and the string is split in order that more characters can be recognized. If unrecognized characters remain in the string, the process is repeated. The joining and splitting operations are repeated until all subsequent characters in the string have been either recognized or determined to be unrecognizable.Type: GrantFiled: September 25, 1992Date of Patent: June 14, 1994Assignee: The Research Foundation, State University of New York at BuffaloInventors: Richard K. Fenrich, Sargur N. Srihari
