Abstract: A spiral-wound tip is presented for use on a walking assistance device, a robotic arm or digit, or other device needing a slip-resistant point of contact with its environment. The tip is constructed by winding a sheet of rubber or other elastic material into a spiral plug. The plug can be mounted within a hole at the extremity of a device. Alternatively, the sheet can be wrapped around the exterior of the extremity. The lamina of the spiral-wound plug separate upon impact with an object, increasing the gripping power of the tip.

Abstract: A method, apparatus and program storage device for verifying existence of a redundant Fiber Channel path is disclosed. The present invention verifies that a redundant path exists prior to moving the WWNN and WWPN. Thus, if the path being used for Fiber Channel communication is lost, connectivity can be restored when the source of the original connection can access the physical interface where the WWNN and WWPN have been moved.

Abstract: An intraoral aversion device to assist a user in quitting an undesirable behavior such as tobacco smoking, tobacco chewing, use of snuff, illicit drug use, excessive alcohol consumption, excessive food consumption, and/or other undesirable activity facilitated via the mouth. The aversion device may be wholly or partially configured to be disposed in the user's mouth, for example. The aversion device may include a detector and a output device, wherein the detector is configured to detect a parameter indicative of the user engaging in the habit or undesirable activity. If (and only if) the detector detects such a parameter, the output device delivers a negative stimulus to the user, thus providing negative feedback and creating an incentive for the user to limit if not eliminate the undesirable activity.

Abstract: An adjustable occlusion device and methods of deploying the device, comprising an actively expandable anchor for use in customizing the fit in a body lumen such as the left atrial appendage. Some embodiments of the actively expandable anchor include a positive force expander as an adjustable occlusion device using intertwining adjustable coils, engageable helical ribbons, or threaded tubes.

Abstract: The present invention is a method and system for simulating fluid flow in a cavity, having relevance to the modeling of viscous flows within thin cavities of complex shapes in which heat exchange with the cavity walls may be a governing factor, as in injection molding of plastic parts. Its automated discretization scheme, in which the model cavity is partitioned into macrocells, each macrocell having substantial contact areas with the model cavity walls, eliminates the need for time consuming and expensive manual model configuration required by some modeling methods. Because of the simplicity of the discretization, models based on the invention are less demanding on computer resources then conventional finite element methods, and execute more quickly. A key innovation of the method is a function characterizing the shape of a macrocell that appears in a coefficient in equations governing the flow.

Abstract: A shared storage distributed file system is presented that provides applications with transparent access to a storage area network (SAN) attached storage device. This is accomplished by providing clients read access to the devices over the SAN and by requiring most write activity to be serialized through a network attached storage (NAS) server. Both the clients and the NAS server are connected to the SAN-attached device over the SAN. Direct read access to the SAN attached device is provided through a local file system on the client. Write access is provided through a remote file system on the client that utilizes the NAS server. A supplemental read path is provided through the NAS server for those circumstances where the local file system is unable to provide valid data reads. Consistency is maintained by comparing modification times in the local and remote file systems.

Abstract: Disclosed is a closure catheter, for closing a tissue opening such as an atrial septal defect, patent foreman ovale, or the left atrial appendage of the heart. The closure catheter carries a plurality of tissue anchors, which may be deployed into tissue surrounding the opening, and used to draw the opening closed. Methods are also disclosed.

Abstract: The present invention relates to an interventional device for interacting with occlusive material. A wall attachment jet moves and removes particulate from lumens such as vessels.

Abstract: A method and device for injecting and extracting fluid at a treatment site to remove debris from the site.

Abstract: A catheter for injecting and extracting fluids to interact with material at a treatment site in the body.

Abstract: Disclosed is a closure catheter, for closing a body cavity such as a vessel, or the left atrial appendage of the heart. The closure catheter includes a plurality of deployable tissue anchors, which may be laterally deployed into surrounding tissue. The anchors may thereafter be used to draw the tissue radially inwardly, to close the body cavity. Methods are also disclosed.

Abstract: A method, apparatus and program storage device for providing virtual disk service hints based storage. Virtual disk service hints are provided. The virtual disk service hints are analyzed to determine a configuration model to implement. The storage system is then configured according to the configuration model identified using the virtual disk service hint.

A plurality of fiber optic bundles corresponds in number at least to the number of ring openings, and at least one fiber optic bundle is arranged at one end of the longitudinal axis for receiving specimen information and at another end of the longitudinal axis connected to a detector for receiving a signal.

Abstract: A method of upgrading firmware during background operation in a storage area network (SAN) including at least one storage controller having programmable memory and RAM, where the at least one storage controller for controls data access between at least one host server and at least one storage device. The method includes temporarily suspending data access commands from the at least one host server, upgrading firmware stored in programmable memory, and copying a current version of firmware in a first memory address of RAM to a second memory address in the RAM. The current version of firmware in the first memory address in RAM is overwritten with the upgraded version of firmware. The controller is reinitialized, and data access commands from the at least one host server to the at least one storage device are provided by the at least one storage controller.

Abstract: A method, apparatus and program storage device for providing intelligent rebuild order selection is a storage array is disclosed. The interrelationship of the data on the drives to be rebuilt and the remaining drives in the system is examined. A relative score for a rebuild record to be rebuilt is based upon the manner in which the RAID data is placed on the other drives. The rebuild record with the highest relative risk is identified as the rebuild record to be rebuilt next.

Abstract: A method, apparatus, and system for preserving the cache data of redundant storage controllers, by copying the recorded data blocks and the associated cache tags in the primary cache memory of a storage controller to a secondary cache memory of an alternate, redundant storage controller, wherein upon a failure occurring in the primary cache memory of any of the storage controllers, subsequent storage requests from a host, previously intended for processing by the failed storage controller, are processed through the secondary cache memory of a non-failed, redundant storage controller that contains the failed storage's controller cache data and cache tags.
