Patent number: 9953246Abstract: A noise removal method includes receiving in a de-noising system multiple noisy copies of a target image; providing the noisy copies as input data to the de-noising system in a training phase, and determine a noise distribution for the plurality of noisy copies. The method further includes, for n stages of the de-noising system, transforming the input data into an output; reconstructing the output; and providing the reconstructed output as input data. The method may further include receiving a new image and generating a de-noised image based on the determined noise distribution.Type: GrantFiled: December 16, 2015Date of Patent: April 24, 2018Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Louis Bouchard, Khalid Youssef

Patent number: 8570035Abstract: A novel approach to magnetic resonance imaging is disclosed. Blood flowing through a living system is prepolarized, and then encoded. The polarization can be achieved using permanent or superconducting magnets. The polarization may be carried out upstream of the region to be encoded or at the place of encoding. In the case of an MRI of a brain, polarization of flowing blood can be effected by placing a magnet over a section of the body such as the heart upstream of the head. Alternatively, polarization and encoding can be effected at the same location. Detection occurs at a remote location, using a separate detection device such as an optical atomic magnetometer, or an inductive Faraday coil. The detector may be placed on the surface of the skin next to a blood vessel such as a jugular vein carrying blood away from the encoded region.Type: GrantFiled: December 12, 2008Date of Patent: October 29, 2013Assignee: The Regents of the University of CaliforniaInventors: David Wemmer, Alexander Pines, Louis Bouchard, Shoujun Xu, Elad Harel, Dmitry Budker, Thomas Lowery, Micah Ledbetter

Patent number: 7191213Abstract: A more efficient message notification system utilizing technology found in Instant Messaging Services. The more efficient system is achieved by first registering a Message Notification Application with an Instant Messaging Service. A user logs onto the Instant Messaging Service and indicates to the Message Notification Application that the user would like to be notified when new messages arrive. The Message Notification Application then adds the user to its own buddy list. The user is notified by the Message Notification Application through the Instant Messaging Service when a message is received. The user can then retrieve messages through an internet appliance with sound capabilities, or by utilizing the voice-to-text conversion capabilities of the application from the voice messaging or unified messaging server, or by more traditional methods such as a telephone.Type: GrantFiled: October 25, 2000Date of Patent: March 13, 2007Assignee: Avaya Technology Corp.Inventors: Louis Bouchard, Dustin M.

Publication number: 20020174184Abstract: A push model notification and access mechanism to “push” the contents of a voice, fax, e-mail or unified mailbox to a wireless device such as a cellular phone where this information is locally cached and almost instantly displayed so that the user can interact with the mailbox content locally without the need to set up or maintain a network connection with a messaging server. The user may then send a command through the wireless device to the server to access particular items of the content list of the mailbox which is refreshed at every new message notification or after the mailbox has been accessed by the user using more traditional methods such as by telephone call.Type: ApplicationFiled: April 25, 2001Publication date: November 21, 2002Applicant: Avaya, Inc.Inventor: Louis Bouchard
