Abstract: A surgical retractor assembly is provided having a frame that releasably couples two retractor blades. The retractor blades are coupled to the frame via a pair of mobile carriages that engage a track on the frame. A third retractor blade is configured to be independent of the frame with the first two retractor blades. The independent blade may be fixably positionable in the patient by a direct coupling to a rigid table mount. The retractor assembly may be utilized for creating anterior access to spinal target site while the patient is oriented in the lateral decubitus position.

Abstract: A storage array controller may receive a write request comprising data to be stored at one or more solid-state storage devices. A write granularity associated with the write request may be generated that is less than a logical block size associated with the storage array controller. The data associated with the write request may be segmented based on the generated write granularity. The write request may be executed to store the segmented data at the one or more solid-state storage devices.

Abstract: A metering pump for a medical injector includes a housing, a sleeve at least partially received within the housing, a piston at least partially received within the sleeve, and an interlock. The piston has a first position where the chamber has a first volume and a second position where the chamber has a second volume, with the first volume larger than the second volume. The sleeve has a first rotational position where an inlet is in fluid communication with the chamber, a second rotational position where an outlet is in fluid communication with the chamber, and a third rotational position where the inlet and outlet are isolated from the chamber. The interlock includes an elastomeric member and a protrusion, where engagement between the elastomeric member and the protrusion is configured to restrict movement of the sleeve until the sleeve overcomes a predetermined torque value.

Abstract: A priority queue including an order of local data relocation operations to be performed by a plurality of solid-state storage devices is maintained. An indication of a new local data relocation operation is received from a solid-state storage device of the plurality of solid-state storage devices for data stored at the solid-state storage device, the indication including information associated with the data. The new local data relocation operation is inserted into a position in the order of the priority queue based on the information associated with the data.

Abstract: One or more performance parameters associated with data stored at a storage device of a plurality of storage devices are received by a storage controller. A first number of blocks of the storage device to a high resiliency portion and a second number of blocks of the storage device to a low resiliency portion of the storage device are allocated based on the one or more performance parameters.

Abstract: Data associated with a write request is stored at a storage device of multiple solid-state storage devices. A determination as to whether the data stored at the storage device is readable is made by determining whether a number of subsequent programming operations have been performed since the data was stored at the storage device. A notification that the stored data is readable from the storage device is generated upon determining that the data is readable.

Abstract: A command to relocate data is transmitted by a storage controller. The command includes first address information associated with a first set of blocks storing the data at one or more storage devices using a first programming mode and second address information associated with a second set of blocks at the one or more storage devices to store the relocated data using a second programming mode. The command causes the relocation of the data from the first set of blocks to the second set of blocks while bypassing sending the data to the storage controller. An acknowledgement is received that the relocated data has been stored at the second number of blocks.

Abstract: A storage unit has one or more processing devices, a solid-state drive and an open blocks cache memory. The open blocks cache memory holds open blocks of data or metadata and holds closed blocks of data or metadata pending writing to the solid-state drive. Closed blocks of data or metadata are written to the solid-state drive and open blocks of data or metadata are written to the open blocks cache memory. Values for open blocks in the open blocks cache memory are tracked. The values are adjusted in a first direction when an open block is written to the open blocks cache memory, and the values are adjusted in a second direction when an open block in the open blocks cache memory is closed and written from the open blocks cache memory to the solid-state drive.

Abstract: Examples described herein relate to a in a group of servers: the servers attempting to perform timing synchronization based on a first group of timing signals sent via a first path. In some examples, the first comprises a first connection and based on disruption of communications by the first connection between servers in the group of servers. In some examples, the servers attempting to perform timing synchronization based on a second group of timing signals sent via a second path. In some examples, the second path does not traverse the first connection.

Abstract: A foldable stringed instrument, for example in the form of a travel guitar that folds mid-neck to assume a reduced profile is described. The mid-neck folding is accomplished in a symmetrical manner about a three-part hinge located in the neck to configure the travel guitar into a reduced profile. The bridge assembly can be translated longitudinally relative to the head of the guitar to allow sufficient detensioning of the guitar strings to enable an upper portion of the neck to be folded away from a lower portion of the neck and/or body to assume a reduced profile. To deploy the travel guitar for playing, the upper portion of the neck is unfolded into alignment with the lower portion of the neck and/or body, and the bridge assembly translated longitudinally relative to the head and locked in position to allow the guitar to be tuned for playing.

Abstract: A surgical retractor assembly is provided that can assume both open and closed positions, and is easily convertible from one position to the other. The retractor assembly involves an arcuate frame member that can be engaged to an arcuate connector, which together form a generally circular or elliptical retractor frame assembly. The frame member has a groove for the insertion of one or more mobile carriages that hold retractor blade posts and allow the posts to move in multiple directions. The carriages may be locked to prevent movement in one or more directions, as well.
