Publication number: 20120250852Abstract: Methods and devices for improved echo cancellation in high noise environments, such as in-car speakerphones and the like, are provided that improve cancellation convergence in a high noise environment and in the presence of double talk. A new update method enables a robust echo canceller to update with reduced concern for the canceller being in a receive state or a double talk state. If a signal generated by a local talker is substantially the same as high noise, in terms of corruption of the echo canceller, the echo canceller converges in a robust manner even with continuous high noise at the input.Type: ApplicationFiled: March 30, 2012Publication date: October 4, 2012Applicant: COGENT SIGNALS, INC.Inventor: David Lee Rowley

Patent number: 8275179Abstract: An apparatus for capturing the image of a wet/moist fingerprint. The apparatus includes: a prism having an imaging plane on which a finger having valleys and ridges is place, a bottom plane parallel to the imaging plane and a reflective plane intercepting the imaging plane and intercepting the bottom plane at an angle ?; a light source for generating a light with an incident angle of approximately 0° with respect to a surface normal of the imaging plane; and a lens for capturing light reflected from the reflective plane. The apparatus further includes an image sensor for generating an image of the valleys and ridges of the finger, wherein the reflective plane is arranged in such a way to meet the equation of ?>45 +(arc sin (n1/n2))/2, where n1 is a refraction index of medium filled between the valleys of the finger and the imaging plane, and n2 is refraction index of the prism.Type: GrantFiled: April 17, 2008Date of Patent: September 25, 2012Assignee: 3M Cogent, Inc.Inventors: Ming Hsieh, Ankuo Wang, Fei Zhou, Wheshi Chen

Patent number: 8254728Abstract: In one embodiment, the present invention is a system for organizing data flow for two dimensional digital image processing. The system includes a memory access module for accessing an external memory containing image data to be processed, and a data flow organizer module for preparing a data stream from the input image data accessed by the memory access module. The data flow organizer module predicts future data needed for processing, and the memory access module pre-fetches the predicted data from the memory. A data processing module processes the pre-fetched data from the data flow organizer module. Address generation for accessing the memory is performed independent and in parallel with processing the pre-fetched data.Type: GrantFiled: July 9, 2009Date of Patent: August 28, 2012Assignee: 3M Cogent, Inc.Inventors: Ming Hsieh, Huansheng Xue, Jing Wang, Chunyu Lu
