Abstract: A biometrics-enabled portable storage device may store and secure data via biometrics related to a user's iris. The biometrics-enabled portable storage device may include a camera that captures image data related a user's iris and stores the image data to enroll the user for use of the biometrics-enabled portable storage device. To unlock the data, a user aligns the camera with their iris using a hot mirror and the camera captures iris data for comparison with the iris image data stored during enrollment. If the two sets of image data match, the biometrics-enabled portable storage device may be unlocked and the user may access data stored on the biometrics-enabled portable storage device. If the two sets of image data do not match, then the biometrics-enabled portable storage device remains locked.

Abstract: A method of time-scale modification processing of frame-based digital audio signals based on Synchronous Overlap Addition in which an original frame of digital audio is copied, the original and copied frames are partly overlapped to give a desired new duration to within a predetermined tolerance, the extent of overlap is adjusted within the predetermined tolerance by reference to a cross correlation determination of the best match between the overlapping portions of the original and copied frame; and a new audio frame is generated from the non-overlapping portions of the original and copied frame and by cross-fading between the overlapping portions. To reduce the computational load, a profiling procedure is applied to the original and copied frame prior to cross correlation, such as to reduce the specification of each audio frame portion (100) to a finite array of values (101–106), and the cross correlation is then performed in relation only to the pair of finite arrays of values.
