Abstract: In order to examine a degree of monocular diplopia is easily examined in a quantitative manner, a plurality of circular eye marks are seen from a predetermined examination distance with a single eye of a patient to find a particular eye mark whose double vision images are observed to be circumscribed each other, and a degree of monocular diplopia is determined by a view angle of the relevant circular eye mark. Since the eye mark is formed as a circular pattern, a degree of monocular diplopia can be examined irrespective of an axial direction along which double vision images appear.

IPC: G01R33/567
Filed: 2004-09-28
Abstract: The invention is directed to techniques in which magnetic resonance imaging (MRI) is coordinated with the operation of an implantable medical device (IMD). By using an IMD to sense conditions, MRI can be improved because the sensed conditions can accurately define timing for application of electromagnetic radiation bursts. Moreover, by applying stimulation pulses specifically to coordinate the electromagnetic radiation bursts, the MRI may also be improved.

Abstract: A method and system for user authentication based on speech recognition and knowledge questions. The method comprises receiving a speech recognition result derived from ASR processing of a received utterance. A reference information element is obtained for the utterance. Then, the method determines at least one similarity metric indicative of a degree of similarity between the speech recognition result and the reference information element. A feature vector is determined from the at least one similarity metric, and a score is computed based on the elements of the feature vector. A classifier may be used to process the elements of the feature vector, with the classifier having been trained to tend to produce higher scores when processing training feature vectors derived from utterances known to convey associated reference information elements than when processing training feature vectors derived from utterances known not to convey said associated reference information elements.
