Abstract: Techniques are provided for failing over an aggregate from one file system instance to a different file system instance of a distributed scale-out storage system. The aggregate may be stored within distributed storage that is accessible to a plurality of file system instances of the distributed scale-out storage system. When the aggregate is failed over from a first file system instance to a second file system instance, the first file system instance may still have a valid read lease that allows the first file system instance to serve client I/O, directed to the aggregate, using a cache. In order to prevent the first file system instance from serving stale data from the cache before the read lease expires, state machines and a set of control data are used to ensure that the second file system instance attaches to the aggregate only after the read lease has expired.

Abstract: A housing of a device comprises a screw boss that extends outwardly from a first base plate proximate to a corner of the housing. Additionally, the housing of the device includes a force dissipation member. The force dissipation member includes a central portion that is sized to detachably attach around the screw boss. The force dissipation member further includes at least two arms that extend outwardly from the central portion, wherein each arm of the at least two arms is attached to a different side of the two walls of the housing.

Abstract: During a maintenance operation and in a predetermined sequence, selected ones of a plurality of gates of a passive balancing electrical network are opened and closed. The passive balancing electrical network is coupled to the plurality of battery cells. The passive balancing electrical network includes multiple unintentional resistances and the multiple unintentional resistances inherent to the plurality of battery cells or a structure of the passive balancing electrical network. These unintentional resistances are utilized to identify location and nature of failures within the network to allow preparing the item for safe handling.

Abstract: An imaging assembly comprises a catheter having a distal end and a proximal end, an ablation tip at the distal end of the catheter, and an imaging device disposed within the ablation tip. The catheter defines a catheter lumen that extends from the proximal end to the distal end. The catheter is configured and arranged for insertion into a body lumen such as a blood vessel or heart chamber. The ablation tip has a wall that defines a lumen in communication with the lumen of the catheter. The imaging device is disposed within the lumen of the ablation tip, and is configured to transmit pulsed acoustic waves for generating images of body tissue at a target ablation site within the body.

Abstract: A metallic tube arrangement includes an electrode region configured to expand radially and contract radially in response to increasing and decreasing a temperature at the electrode region, respectively. The electrode region is configured for intravascular deployment and delivery of high frequency energy to target tissue of a target vessel of the body. The electrode region is configured to expand radially to a diameter sufficient to contact an inner wall of the target vessel in response to a decrease in electrode region temperature and to contract radially to a diameter smaller than a diameter of the target vessel in response to an increase in electrode region temperature.

Abstract: The disclosure pertains to a device for cutting a suture in a fluid environment which isolates a portion of the suture to be cut within a substantially sealed environment and cuts the suture thermally by using an electrically heated element within the chamber. In another embodiment, the disclosure relates to a vascular sealing system including the suture cutting device and a method of use thereof.
