Opnet Technologies, Inc. - Bethesda MD

International Classification:

G06F 11/00

US Classification:

370228

Abstract:

A path-flow formulation of defining MPLS FRR bypass LSPs is presented. The path-flow formulation comprises first identifying a set of candidate bypass LSPs, each of which meets various network constraints and has an explicit route around a network facility to be protected. The constraints may include Quality of Service (QoS) guarantees, implementation requirements, network element resource limitations, and resiliency requirements. The constraints may be user-selected, and may be non-linear. The set of candidate bypass LSPs form a linear programming (LP) problem, or an integer linear programming (ILP) problem if the allowable number of bypass LSPs is constrained. In an optimization step, LP solutions are used to select the bypass LSPs from among the candidate bypass LSPs by allocating bandwidth to them.

Assignee:

ST. JUDE MEDICAL, INC. - St. Paul MN

International Classification:

A61B 6/00
A61B 8/00

US Classification:

600427, 600425

Abstract:

A method for performing elastographic deformation mapping of tissues and plaques comprises: introducing a distal portion of a catheter to an interior of an interior body of a patient; applying, from a palpator in the distal portion, one of a directed fluid or a mechanical indenter to produce a surface-applied palpation force to a target area of the interior body to mechanically displace the interior body and cause elastographic deformation of the target area of one or more surface and subsurface tissues and plaques; and directing and delivering an OCT (optical coherence tomography) beam, from an OCT imaging sensor in the distal portion, for OCT deformation detection including elastographic deformation measurement to provide elastographic mapping of the target area.

US Classification:

600427, 600425

Abstract:

An optical coherence tomography (OCT) catheter, for performing high performance elastographic deformation mapping of tissues and plaques, comprises: a catheter having elongated catheter body extending longitudinally between a proximal end and a distal end along a longitudinal axis, the catheter body including a distal portion at the distal end and a catheter lumen; a palpator, disposed in the distal portion, to apply one of a directed fluid or a mechanical indenter to produce a surface-applied palpation force to a target area of the interior body to mechanically displace the interior body and cause elastographic deformation of the target area of one or more surface and subsurface tissues and plaques; and OCT imaging sensor, disposed in the distal portion, to direct and deliver OCT beam for OCT deformation detection including elastographic deformation measurement to provide elastographic mapping of the target area.

International Classification:

G06F 1/00

US Classification:

713300

Abstract:

An apparatus and method for transferring power in an inline switch device are provided. The method comprises drawing power from an inline power source and transferring, by the powered device subsystem, a portion of the power that is not consumed by the powered device subsystem to one or more connected powered devices. The method further comprises determining a limit of current drawn by the powered device subsystem during transfer of power by the powered device subsystem to the one or more powered devices that results in the transfer of a desired amount of power to the one or more powered devices, and adjusting the limit for the current drawn by the powered device subsystem to the determined current limit.

International Classification:

H04L 9/40
H04L 41/0806

Abstract:

An authentication system facilitates efficient generation of authentication integrations with third-party identity providers for client systems. The authentication system provides one or more interfaces configured to receive requests to make authentication integrations available for a third-party identity provider. The requests to make authentication integrations available include integration information for the relevant identity provider. Based on the request to make authentication integrations available, the authentication system generates an identity provider profile for the identity provider that can be used to generate authentication integrations with the identity provider for one or more client systems. Once the identity provider profile is generated, the authentication system uses the identity provider profile to generate authentication integrations for one or more client systems that request authentication through the third-party identity provider. In doing so, the authentication system provides an efficient process for providing authentication integrations with identity providers requested by client systems.

Yu Liu - Milpitas CA, US

International Classification:

G06F 16/215

Abstract:

A first group of chunk identifiers associated with a first content identifier structure of a first metadata element and a second group of chunk identifiers associated with a second content identifier structure of a second metadata element are determined. A common sequence of chunk identifiers across at least a portion of the first group of chunk identifiers associated with the first content identifier structure and the second group of chunk identifiers associated with the second content identifier structure is determined. A portion of the first group of chunk identifiers associated with the first content identifier structure and a portion of the second group of chunk identifiers associated with the second content identifier structure is updated to reference a common sequence identifier in place of the determined common sequence of chunk identifiers.

G06F 16/957

Abstract:

According to aspects of the disclosed subject matter, a taste graph comprising likely content collection nodes with corresponding likely digital content items is generated through one or more analyses of a corpus of content collections that is maintained by the online content service. As should be understood, this corpus of content collections is comprised of a plurality of curated content collections, with each content collection comprising a plurality of digital content items. With this taste graph available, as a user generates (or in response to a user generating) a content collection of digital content items, reference can be made to the taste graph to identify one or more digital content items that may be added to the content collection, where the one or more digital content items have a probabilistic likelihood of being complimentary and/or compatible with the other digital content items of the content collection.
