Publication number: 20200274936Abstract: Described herein are method and apparatus for servicing software components of nodes of a cluster storage system. During data-access sessions with clients, client IDs and file handles for accessing files are produced and stored to clients and stored (as session data) to each node. A serviced node is taken offline, whereby network connections to clients are disconnected. Each disconnected client is configured to retain its client ID and file handles and attempt reconnections. Session data of the serviced node is made available to a partner node (by transferring session data to the partner node). After clients have reconnected to the partner node, the clients may use the retained client IDs and file handles to continue a data-access session with the partner node since the partner node has access to the session data of the serviced node and thus will recognize and accept the retained client ID and file handles.Type: ApplicationFiled: May 12, 2020Publication date: August 27, 2020Inventors: Paul Yuedong Mu, Nam Le, John Hoffmann, John Boyles

Patent number: 10695027Abstract: A multiple aperture ultrasound imaging system may be configured to store raw, un-beamformed echo data. Stored echo data may be retrieved and re-beamformed using modified parameters in order to enhance the image or to reveal information that was not visible or not discernible in an original image. Raw echo data may also be transmitted over a network and beamformed by a remote device that is not physically proximate to the probe performing imaging. Such systems may allow physicians or other practitioners to manipulate echo data as though they were imaging the patient directly, even without the patient being present. Many unique diagnostic opportunities are made possible by such systems and methods.Type: GrantFiled: June 5, 2018Date of Patent: June 30, 2020Assignee: MAUI IMAGING, INC.Inventors: Josef R. Call, Kenneth D. Brewer, Viet Nam Le, Matthew Ouellette, Mathias Blake

Patent number: 10546966Abstract: A lightweight photovoltaic module including: a first transparent layer forming the front face; photovoltaic cells; an assembly encapsulating the photovoltaic cells; and a second layer forming the rear face and containing an inner surface and an outer surface. The encapsulating assembly and the photovoltaic cells are located between the first and second layers. The module is characterized in that: the first layer is made from glass and/or polymer material and has a thickness that is less than or equal to 1.1 mm; the inner surface is substantially planar; and the second layer includes raised portions projecting from the outer surface, the outer surface and raised portions together defining the visible rear outer surface of the photovoltaic module.Type: GrantFiled: November 14, 2016Date of Patent: January 28, 2020Assignees: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES, EDF ENR PWTInventors: Julien Gaume, Paul Lefillastre, Gilles Goaer, Nam Le Quang, Samuel Williatte

Publication number: 20200003896Abstract: Systems and methods for network-based ultrasound imaging are provided, which can include a number of features. In some embodiments, an ultrasound imaging system images an object with three-dimensional unfocused pings and obtains digital sample sets from a plurality of receiver elements. A sub-set of the digital sample sets can be electronically transferred to a remote server, where the sub-set can be beamformed to produce a series of two-dimensional image frames. A video stream made up of the series of two-dimensional images frames can then be transferred from the remote server to a display device.Type: ApplicationFiled: September 3, 2019Publication date: January 2, 2020Inventors: Josef R. Call, Henry A. Davis, David M. Smith, David J. Specht, Viet Nam Le, Lang J. McHardy, Joseph James Digiovanni, II, Nathan W. Osborn, Bruce R. Ritzi

Publication number: 20190200961Abstract: A method of full-field or “ping-based” Doppler ultrasound imaging allows for detection of Doppler signals indicating moving reflectors at any point in an imaging field without the need to predefine range gates. In various embodiments, such whole-field Doppler imaging methods may include transmitting a Doppler ping from a transmit aperture, receiving echoes of the Doppler ping with one or more separate receive apertures, detecting Doppler signals and determining the speed of moving reflectors. In some embodiments, the system also provides the ability to determine the direction of motion by solving a set of simultaneous equations based on echo data received by multiple receive apertures.Type: ApplicationFiled: March 11, 2019Publication date: July 4, 2019Applicant: MAUI IMAGING, INC.Inventors: Donald F. SPECHT, Kenneth D. BREWER, David M. SMITH, Josef R. CALL, Viet Nam LE, Bruce R. RITZI
