Abstract: Disclosed embodiments relate to devices and systems for providing both negative-pressure therapy and instillation, In some embodiments, both negative-pressure and instillation may be provided to a tissue site in a low-profile context that may also prevent siphoning of instillation fluid during negative pressure application. For example, a single bridge may include a negative-pressure pathway with supports and an instillation pathway, and the instillation pathway may be configured with respect to the negative-pressure pathway so that at least a portion of the instillation pathway collapses upon application of negative pressure to the negative-pressure pathway. Collapse of at least a portion of the instillation pathway may be sufficient to close the instillation pathway.

Abstract: An electric motor built for exposure to high pressure fluid includes a unitary metal sleeve that provides a fluid barrier between the rotor and the stator. An overmolded resin encapsulates the stator windings and reinforces the sleeve to minimize deformation of the sleeve under high fluid pressures. The overmolded resin also fixes the positions of insulation displacement connectors connected to the stator windings, thereby avoiding mechanical brackets and fasteners for holding the insulation displacement connectors in position.

Abstract: In some non-limiting examples, a system for stimulating tissue growth at a tissue site may include a porous foam and a moisture barrier. The porous foam may include an exterior-facing surface, a tissue contact surface, and a plurality of struts positioned at the tissue contact surface. The plurality of struts may be configured to contact the tissue site and to create tissue deformation at the tissue site without the application of a reduced pressure. The moisture barrier may be configured to cover the exterior-facing surface of the porous foam and to trap moisture at the tissue site. Also provided are other systems, apparatus, and methods suitable for stimulating tissue growth.

Abstract: A dressing interface for connecting a negative-pressure source to a dressing may have a coupling member comprising an aperture, a first adhesive region having a first region peel strength, and a second adhesive region having a second region peel strength less than the first region peel strength. The dressing interface may further have a flange coupled to the coupling member, and a conduit housing coupled to the flange and extending through the aperture in the contact layer.

Abstract: Techniques for continuous lock-minimal checkpointing and recovery with a distributed log-based datastore are described. A continuous, fault-tolerant checkpoint process is run on a node in a cluster in a compute-optimized or memory-optimized manner, thereby checkpointing the in-memory replica state of the node to a durable checkpoint datastore. A node can partially restore its replica state by obtaining checkpoint data, which includes an identifier of a low-water mark in a journal shard. The node can attach to the journal shard using the low-mater mark as the point of attachment, enabling the node to finalize the restoration of the replica state to be current.

Abstract: A dressing that includes a contact layer having walls defining a plurality of holes and a retainer layer comprising portions protruding into holes of a contact layer is provided herein. Systems, methods and kits using the dressing for debriding a tissue site are also provided herein.

Abstract: Techniques for multi-stream transactional event processing under ACID semantics in a distributed log-based append-only datastore are described. A transaction coordinator writes events that are part of a transaction to a transaction buffer, where the events can be made visible to clients involved in the transaction while other clients are not aware. Upon committing the transaction, an optimistic concurrency control based technique is utilized to attempt to obtain locks on all events involved in the transaction across one or multiple shards by one or multiple designated writer nodes. When all involved writer nodes indicate that they are able to commit their events, the transaction can be committed.

Abstract: An apparatus for treating a tissue site comprising a negative-pressure source configured to be fluidly coupled to the tissue site; an instillation source configured to be fluidly coupled to the tissue site; and a controller operatively coupled to the negative-pressure source and to the instillation source. The controller can be configured to operate the negative-pressure source and the instillation source to intermittently deliver negative pressure to the tissue site for a negative-pressure interval and deliver instillation fluid to the tissue site for an instillation interval. A purge volume of instillation fluid may be delivered to the tissue site at a purge frequency. In some examples, the purge volume may be delivered through the second fluid conductor and removed through the first fluid conductor during a negative-pressure interval.

Abstract: The present disclosure generally relates to enabling migration of services between a first and second environment, while maintaining a local availability of those servers within the first environment. Specifically, embodiments enable the services to remain locally available with the first environment without modification of operation of clients within the first environment. A migration gateway is provided in the first environment that, on migration of a service from the first to the second environment, can announce availability of the service at the gateway. The gateway can then act as a proxy for the service in the second environment. In one configuration, the gateway adopts an Internet Protocol (IP) address of a server that has been migrated, such that clients may be unaware that migration has occurred.

Abstract: A lighting assembly can be quickly and efficiently mounted to a crown of a drilling rig derrick in order to provide wide-area illumination of the derrick and surrounding work location. An adjustable support frame member can be operationally attached to a hand rail of a derrick crown using fixed-length bracket members, adjustable-length bracket members and/or a combination(s) thereof. Lighting-emitting light source elements are adjustably attached to the support frame, and can be selectively aimed to direct light as desired.

Abstract: A straight line lamination for an electric motor has alternating finger segments and hinge segments to be rollable after windings are installed to form a circular motor stator. The lamination is configured such that inner edges of a back iron region are non-arcuate in shape to provide extra back iron material near the hinge segments for mitigating torque constant roll off.

Abstract: One embodiment relates to a method of measuring overlay errors for a programmable pattern, area-imaging electron beam lithography apparatus. Patterned cells of an overlay measurement target array may be printed in swaths such that they are superposed on patterned cells of a first (base) array. In addition, the overlay array may have controlled-exposure areas distributed within the swaths. The superposed cells of the overlay and base arrays are imaged. The overlay errors are then measured based on distortions between the two arrays in the image data. Alternatively, non-imaging methods, such as using scatterometry, may be used. Another embodiment relates to a method for correcting overlay errors for an electron beam lithography apparatus. Overlay errors for a pattern to be printed are determined based on within-swath exposure conditions. The pattern is then pre-distorted to compensate for the overlay errors. Other embodiments, aspects and features are also disclosed.
