Abstract: A system includes a plurality of clustered servers, a plurality of clients communicating with the plurality of clustered servers, and a grace database. Each of the plurality of clustered servers maintains a respective client recovery list. A client of the plurality of clients is configured to send a reclaim request to a server of the plurality of clustered servers. The grace database is configured to maintain an epoch value and a reclaim value. The epoch value indicates the current epoch, and the reclaim value indicates from which epoch reclaim is allowed. The server of the plurality of clustered servers is configured to maintain a client list and receive the reclaim request from the client. The client list indicates each client currently holding state on the server.

Abstract: The technology disclosed herein that may enable a client of a distributed storage system to recover a storage session after a failure occurs. An example method may include: identifying a storage session of a distributed storage service, the storage session comprising session data that corresponds to a storage object of the distributed storage service; providing, by a processing device of a client, an indication that the client is recovering the storage session; and obtaining, by the client, the session data of the storage session from one or more devices that accessed the storage object of the distributed storage service.

Abstract: The invention provides a spatially-selective reflective structure for the detection of submillimeter electromagnetic waves and systems and methods incorporating spatially-selective reflective structures. One aspect of the invention provides a spatially-selective reflective structure including a partially-conducting slab and a modulating reflector disk adjacent to the partially-conducting slab. The modulating reflector disk includes a plurality of modulations. Another aspect of the invention provides a submillimeter imaging device including submillimeter wave optics, a spatially-selective reflective structure located in the focal plane of the submillimeter wave optics, a submillimeter wave receiver positioned to capture waves reflected from the spatially-selective reflective structure, and a motor configured to rotate the spatially-selective reflective structure.

Abstract: A voice integration platform and method provide for integration of a voice interface with a data system that includes stored data. The voice integration platform comprises one or more generic software components, the generic software components being configured to enable development of a specific voice user interface that is designed to interact with the data system in order to present the stored data to a user.

Abstract: A disc brake uses retraction springs arranged in directions transverse to the direction of movement of the brake pads. The springs thus apply both tangential and radial forces to the brake pads to both retract the pads and to reduce rattle. In the preferred embodiment, the springs are S-shaped and attached to the pad backing plates by insertion of the ends of the springs into holes in the backing plates.
