Abstract: The method for storing streaming media includes receiving, from a user device, a request to navigate to a requested time of a media stream. The method also includes determining whether a block of media segments that have a time interval that overlaps with the requested time is stored at the server. The method also includes retrieving the block of media segments from long-term memory in accordance with a determination that the block of media segments is not stored at the server. The method also includes traversing the block of media segments that have a time interval that overlaps with the requested time of the media stream to seek and identify a media segment corresponding to the requested time of the media stream. The method also includes streaming a media stream to the user device that begins at the media segment corresponding to the requested time of the media stream.

Abstract: An unmanned, towable air vehicle is described and includes electronic sensors to increase the detection range relative to the horizon detection limitations of a surface craft, an autogyro assembly to provide lift, and a controller to control operation the autogyro assembly for unmanned flight. A forward motive force powers the autogyro assembly to provide lift. In an example, the autogyro assembly includes a mast extending from the container, a rotatable hub on an end of the mast, and a plurality of blades connected to the hub for rotation to provide lift to the vehicle. In an example, an electrical motor rotates the blades prior to lift off to assist in take off. The electrical motor does not have enough power to sustain flight of the vehicle in an example.

Abstract: A metallic alloy whose primary constituent elements are a relatively higher volume fraction of titanium and a relatively lower volume fraction of an added element or elements generally selected from the transition elements (excluding mercury, cadmium, osmium and copper). Medical devices formed from the metallic alloy are visible under MRI imaging and are sufficiently radiopaque for viewing by x-ray fluoroscopy. The alloy may be embodied in a multitude of medical devices.

Abstract: Medical devices are manufactured from fine grained materials, processed from of a variety of metals and alloys, such as stainless steel, cobalt-chromium and nickel-titanium alloys. A fine grained metal or alloy is formed from a specimen rapidly heated to its recrystallization temperature, and then subjected to high temperature, multi-axial deformation, for example, by heavy cross-forging or swaging. The deformed specimen may be cooled and reheated to a second recrystallization temperature. The metal or alloy in the specimen is then allowed to recrystallize, such that the grain size is controlled by quenching the specimen to room temperature. A desired medical device is then configured from the fine grained material. Decreasing the average grain size of a substrate material and increasing the number of grains across a thickness of a strut or similar component of the medical device increases the strength of the device and imparts other beneficial properties into the device.

Abstract: A remote information server contains at least one set of object data bases, with each set including a first object data base containing information content components and a separate second object data base containing context information pertaining to linkages between the information content components of the first object data base of the same set of object data bases. Information content object files respectively containing at least one information content component from the first object data base in the remote information server are delivered to respective local information servers when requested or directed and cached in the respective local information servers. The entire second object data base(s) of context information are delivered from the remote information server to, and maintained in, a plurality of broker/servers. A set of the local information servers is coupled to each broker/server.
