Patent number: 8989855Abstract: A signal processing module includes an input module electronically coupled to a sensing probe of a nerve integrity monitoring system. The probe senses electrical signals from a patient during operation of an electrosurgical unit. The input module receives an input signal from the probe. An EMG detection module is coupled to the input module and is adapted to detect conditions in the input signal. The conditions are classified as a function of a level of electromyographic activity. An output module, coupled to the EMG detection module, provides an indication of electromyographic activity in the input signal based on the detected conditions.Type: GrantFiled: January 30, 2009Date of Patent: March 24, 2015Assignee: Medtronic Xomed, Inc.Inventors: John Murdock Murphy, John A. Meyer, Adnorin Luis Mendez, Kevin Lee McFarlin, David C. Hacker

Publication number: 20070281701Abstract: It is determined whether a location of a mobile device is within a coverage region of a first information service. Communications for the first information service ate redirected to a second information service when the location of the mobile device is not within a coverage region of the first information service The second information service generally has a coverage region encompassing the location of the mobile device. Communications between a mobile device and a first information service ate redirected to another information service when properties of the new information service ale determined to meet predetermined criteria set by a user of the mobile device, by an application, or both. In yet another aspect of the invention, Replacement of information services can be “aggressive” or “non-aggressive.” Communications between a mobile device and an original information service are redirected to another information service when the original information service fails.Type: ApplicationFiled: August 15, 2007Publication date: December 6, 2007Applicant: International Business Machines CorporationInventors: Alan Cole, Sastry Duri, Jonathan Munson, John Murdock

Patent number: 6956899Abstract: A method and system for encoding digital video picture data. In accordance with this method, the video picture data is partitioned into a group of blocks, at least some of those blocks are selected, one block at a time, and each of the selected blocks of data is encoded to form an encoded coefficient having an associated number of bits. The encoded coefficients are outputted, and an accumulated sum of the number of bits in the outputted encoded coefficients is kept. The outputting of the encoded coefficients is terminated at a defined time in order to prevent the accumulated sum from exceeding a given number.Type: GrantFiled: March 23, 1998Date of Patent: October 18, 2005Assignee: International Business Machines CorporationInventors: Barbara A.
