Publication number: 20070081667Abstract: A method for authenticating a user to a computer system is disclosed, comprising using a first input and a second input in producing a digital signature in response to a challenge. The digital signature is valid when the first input matches a personalized secret and the second input matches a trio comprising a public modulus, a public exponent, and a private-key-dependent exponent. Selection of the personalized secret is discretionary and changeable. A crypto-key generation process uses the personalized secret and two primes as input to produce the trio. The public modulus and public exponent of the trio form a public key used in digital signature validation. Also disclosed is a business method that replaces the conventional public-key certificate with an agreement on the user's public key.Type: ApplicationFiled: October 6, 2006Publication date: April 12, 2007Inventor: Jing-Jang Hwang

Publication number: 20070081668Abstract: A block cipher mode of operation implements a block cipher with an arbitrary block length and provides output ciphertext that is always the same size as the input plaintext. The mode can provide the best possible security in systems that cannot allow data expansion, such as disk-block encryption and some network protocols. The mode accepts an additional input, which can be used to protect against attacks that manipulate the ciphertext by rearranging the ciphertext blocks. The universal hash function from Galois/Counter Mode of operation for block ciphers may be used in an embodiment for hardware and software efficiency.Type: ApplicationFiled: August 10, 2005Publication date: April 12, 2007Inventors: David McGrew, Scott Fluhrer

Publication number: 20070081683Abstract: A system and method for improving sound quality for subjects with impaired hearing by applying a lowpass filter and a set of mid- to high-frequency narrowband filters to a signal. A set of narrowband filters are applied to sounds so that the impaired ear is stimulated to respond in a manner more similar to that of a healthy ear at low to moderate sound levels, for which intelligibility is high. Information falling outside of the set of narrowband filters is “discarded” or filtered out, which preserves the representation of the information in the narrowbands. Because energy at frequencies between the narrowband filters is discarded, the sound spectrum is significantly changed, resulting in a clearer sound that is more natural and higher in intelligibility than conventional sounds or sound processing techniques.Type: ApplicationFiled: October 9, 2006Publication date: April 12, 2007Applicant: SYRACUSE UNIVERSITYInventor: Laurel Carney

Publication number: 20070081709Abstract: A clinical and training apparatus that collects and processes physical space data while performing an image-guided procedure on an anatomical area of interest includes a calibration probe, a tracked ultrasonic probe, a wireless tracking device that tracks the ultrasonic probe in space and an image data processor. The physical space data provides three-dimensional coordinates for each of the physical points. The image data processor includes a memory holding instructions. The instructions include determining registrations used to indicate position in image space and physical space; using the registrations to map into image space, image data describing the physical space of the tracked ultrasonic probe and the anatomical area of interest; and constructing a three-dimensional (3D) volume based on ultrasonic image data. The apparatus includes a storage medium that stores a plurality of 3D volumes acquired by the image data processor for later retrieval.Type: ApplicationFiled: September 27, 2006Publication date: April 12, 2007Applicant: VANDERBILT UNIVERSITYInventors: John Warmath, Alan Herline

Publication number: 20070081710Abstract: A system for segmenting a target organ tumor from an image includes a background model builder, a foreground model builder and a tumor region locator. The background model builder uses an intensity distribution estimate of voxels in an organ region in an image to build a background model. The foreground model builder uses an intensity distribution estimate of voxels in a target organ tumor to build a first foreground model. The tumor region locator uses the background model and the first foreground model to segment the target organ tumor to obtain a first segmentation result.Type: ApplicationFiled: October 2, 2006Publication date: April 12, 2007Applicant: SIEMENS CORPORATE RESEARCH, INC.Inventors: Lin Hong, Hong Shen

Publication number: 20070081714Abstract: The invention provides inter alia methods and apparatus for determining the pose, e.g., position along x-, y- and z-axes, pitch, roll and yaw (or one or more characteristics of that pose) of an object in three dimensions by triangulation of data gleaned from multiple images of the object. Thus, for example, in one aspect, the invention provides a method for 3D machine vision in which, during a calibration step, multiple cameras disposed to acquire images of the object from different respective viewpoints are calibrated to discern a mapping function that identifies rays in 3D space emanating from each respective camera's lens that correspond to pixel locations in that camera's field of view. In a training step, functionality associated with the cameras is trained to recognize expected patterns in images to be acquired of the object.Type: ApplicationFiled: October 7, 2005Publication date: April 12, 2007Inventors: Aaron Wallack, David Michael

Publication number: 20070081715Abstract: A method for inspecting moving web material on a label application unit is provided. The web material includes repeated, pre-printed sections wherein each section corresponds to an individual package unit. The method includes detecting a position indicator located on the web material using a sensor where multiple sections of the moving web material includes a position indicator. A die section is moved in response to detection of the position indicator to re-position the die section for a cutting operation. It is determined whether movement of the die section is beyond a predetermined range using a processor. One or more of the method steps are repeated for more than one pre-printed section of the moving web material.Type: ApplicationFiled: October 3, 2006Publication date: April 12, 2007Inventors: Michael Chaput, Willard Lucey, Charles Malony

Publication number: 20070081716Abstract: Provided are an image processing apparatus and method which can adjust the disparity of an input three-dimensional (3D) image and stably display the 3D image. The image processing apparatus includes: an image dividing unit receiving a 3D image and dividing the 3D image into a left-eye image and a right-eye image; a histogram generation unit estimating disparities between the left-eye image and the right-eye image, measuring a frequency with which the estimated disparities occur, and generating a histogram of the disparities and the frequency; a horizontal movement value determination unit determining a horizontal movement value for the left-eye image and the right-eye image using the generated histogram; and a horizontal movement unit moving the left-eye image and the right-eye image horizontally based on the determined horizontal movement value. The image processing apparatus can control convergence of an image to enhance 3D effects and reduce eye fatigue.Type: ApplicationFiled: October 12, 2006Publication date: April 12, 2007Inventors: Tae-hyeun Ha, Jae-phil Koo
