摘要:
A heterogeneous body having ceramic rich cermet regions in a more ductile metal matrix. The heterogeneous bodies are formed by thermal spray operations on metal substrates. The thermal spray operations apply heat to a cermet powder and project it onto a solid substrate. The cermet powder is composed of complex composite particles in which a ceramic-metallic core particle is coated with a matrix precursor. The cermet regions are generally comprised of ceramic-metallic composites that correspond approximately to the core particles. The cermet regions are approximately lenticular shaped with an average width that is at least approximately twice the average thickness. The cermet regions are imbedded within the matrix and generally isolated from one another. They have obverse and reverse surfaces. The matrix is formed from the matrix precursor coating on the core particles. The amount of heat applied during the formation of the heterogeneous body is controlled so that the core particles soften but do not become so fluid that they disperse throughout the matrix phase. The force of the impact on the surface of the substrate tends to flatten them. The flattened cermet regions tend to be approximately aligned with one another in the body.

The present invention provides a method and system for providing advice and/or services to a consumer including the secure electronic storage of rich private personal data preferably held on behalf of persons entities. The system provides the applications, processes, controls and data management services to collect, transfer, store and selectively retrieve data necessary to perform specified planning and decision support activities that have been integrated with the secure data store. The invention provides for the data owner and authorized persons to gain access to accessible data to undertake permitted tasks. These tasks may include receiving data, or undertaking planning, or such other tasks as prescribed. In an embodiment, the system limits access to applications to authorized persons and requires permissions from the owner in order to manage data privacy standards. The system allows the owner to provide and revoke access to applications and tracks and records all access events.

A superabrasive fracture resistant compact is formed by depositing successive layers of ceramic throughout the network of open pores in a thermally stable self-bonded polycrystalline diamond or cubic boron nitride preform. The void volume in the preform is from approximately 2 to 10 percent of the volume of the preform, and the average pore size is below approximately 3000 nanometers. The preform is evacuated and infiltrated under at least about 1500 pounds per square inch pressure with a liquid pre-ceramic polymerizable precursor. The precursor is infiltrated into the preform at or below the boiling point of the precursor. The precursor is polymerized into a solid phase material. The excess is removed from the outside of the preform, and the polymer is pyrolized to form a ceramic. The process is repeated at least once more so as to achieve upwards of 90 percent filling of the original void volume. When the remaining void volume drops below about 1 percent the physical properties of the compact, such as fracture resistance, improve substantially. Multiple infiltration cycles result in the deposition of sufficient ceramic to reduce the void volume to below 0.5 percent. The fracture resistance of the compacts in which the poes are lined with formed in situ ceramic is generally at least one and one-half times that of the starting preforms.

In one embodiment, a method receives a request for a video stream of video content from a client. A playlist for the video stream is retrieved. The playlist is for a plurality of portions of video content. A traffic shaping service adjusts the playlist for a set of portions in the plurality of portions according to a set of rules where adjusting allows the service to perform traffic shaping for the set of portions. The method then sends the adjusted playlist to the client. During playback of the video content at the client, the traffic shaping service receives a request for a portion in the set of portions from the client using the adjusted playlist. The method determines a rule to apply to the portion where the rule is associated with a network condition and simulates the network condition for the portion to perform the traffic shaping service.

The present invention provides a method and system for providing advice and/or services to a consumer including the secure electronic storage of rich private personal data preferably held in trust for and on behalf of a natural person or nominated business or corporate entities. The system provides the applications, processes, controls and data management services to collect from various sources, transfer, store and selectively retrieve data necessary to perform a range of specified planning and decision support activities or events, for which specific applications have been integrated with the secure data store for these purposes. The invention provides for the data owner and authorised persons such as advice and service providers to gain authenticated access to accessible data to undertake permitted tasks. These tasks may include receiving data or record views, or undertaking planning or decision support strategies, or such other tasks as are prescribed. In an embodiment, the system limits access to applications to approved authorised persons and requires specific permissions from the owner in order to manage data privacy standards. The system allows the owner to provide and revoke access permissions to applications and tracks and records all access events.

A computer-implemented method and apparatus of searching a plurality of queries against at least one database containing a plurality of records. The plurality of queries is partitioned into a set of smaller subsets of queries. The at least one database is portioned into a set of smaller subdatabases. Searching tasks to be performed are designated by associating each of said subsets of queries with one or more of said subdatabases, assigning each searching task to one of a group of computers operating in parallel, wherein each member of the group of computers operating in parallel has at least one searching task assigned thereto, and executing at least some of the assigned searching tasks using the group of computers operating in parallel. Search results are collected from the executed searching tasks and a unified search result is generated in accordance with the collected search results.

A cargo box inner comprised of a center floor panel, a pair of outboard floor panels, a pair of sidewall panels, and an understructure framework, with one or more of these parts comprised of aluminum. The sidewall panels surround a cargo bed and extend from the outboard panels by a predetermined angle. The outboard panels extend from a pair of opposing side portions of the center floor panel. These side portions are offset from a longitudinal axis of the center floor panel. The center floor panel and the outboard floor panels are attached to the understructure framework, which includes a pair of longitudinal rails and a series of lateral rails. Each longitudinal rail defines a slot and a channel in open communication with the cargo bed for receiving a fastener and securing a cargo item to the vehicle.

The present invention is a metallic composite which is resistant to erosion and corrosion at the high temperatures and pressures which are encountered in gun tubes, including projectile launchers. This composite comprises a ductile layer of rhenium or a rhenium alloy containing more than 20 percent rhenium, and a layer of a lower cost high strength material such as steel, nickel, nickel alloy, cobalt, or cobalt alloy. A solid solution of the two metals is formed between the two layers making a metallurgical bond. The metallurgical bond may be enhanced through the use of a bond promoter having solubility with both metallic layers.

In one embodiment, a method includes retrieving a playlist for a video stream of video content for a client. The playlist is for portions of video content for the video stream. A traffic shaping service determines a set of rules for the playlist for a set of portions in the plurality of portions where each rule is associated with a network condition. For each rule, the method performs: dynamically allocating a port and setting a network condition to apply to the port according to the rule. During playback of the video content, the traffic shaping service receives a request for a portion from the client and determines a port associated with the request for the portion. The method then sends a traffic shaped portion through the determined port where the network condition is applied to the traffic shaped portion based on the network condition being set on the port.
