An apparatus and method to enhance existing caches in a network to better support streaming media storage and distribution. Helper machines are used inside the network to implement several methods which support streaming media including segmentation of streaming media objects into smaller units, cooperation of Helper machines, and novel placement and replacement policies for segments of media objects.

A composition and method for use in drilling or completing a subterranean well comprising a solids free, high-density brine composed of alkali metal polytungstate and blends thereof. These high-density brines are also useful as wellbore fluids and other non-oilfield fluids requiring high density properties.

An industrial robot that uses a simulated force vector to allow a work piece held by the robot end effector to be mated with a work piece whose location and orientation is not precisely known to the robot. When the end effector makes contact with the location and orientation in which the other work piece is held the robot provides a velocity command to minimize the force of the contact and also provides a search pattern in all directions and orientations to cause the end effector to bring the work piece it is holding in contact with the other work piece. The search pattern and the velocity command are continued until the two work pieces mate.

A system and method of allocating a resource to a service request. Servers are virtually assigned through a hierarchy including groups of servers and super groups of the groups of servers. Each service request type is associated with a service index that determines both a super group and a load balancing policy for that service request type. A load balancing policy may be applied to select a group of servers among several server groups associated with the super group. Another load balancing policy is applied to the selected group of servers to select a server to handle the service request. The hierarchical data structure allows servers to be configured into overlappable, arbitrary subsets that can address service requests matching configured content rules. Load balancing policies can be selected by service request type.

The present invention discloses a system for implementing multimedia ring back tone service, which includes a communication network, an MRBT platform storing multimedia ring back tones in the communication network and a VIG. The MRBT platform is respectively connected to the Service Switch Center dominating the terminal and an MGW in the communication network through the VIG; when a calling terminal initiates a call through the Service Switch Center, the VIG establishes a communication link from the terminal to the MRBT platform through the MGW and the VIG before the call is put through; and MRBT platform plays multimedia ring back tones for the calling terminal via the established communication link. The present invention also provides a method for implementing multimedia ring back tone service. The system and the method provided in the present invention can implement multimedia ring back tone service in 3G communication networks.

The invention includes a method and apparatus for generating a coincidence count table adapted for determining at least one flow statistic. The method includes receiving a plurality of packets comprising a respective plurality of payloads, comparing payloads associated with consecutive ones of the plurality of packets for identifying at least one simple pattern included within the compared payloads of the consecutive ones of the plurality of packets, for each of the consecutive ones of the plurality of packets, if the at least one simple pattern is identified, processing the at least one simple pattern to form a complex pattern, and for each complex pattern, updating a coincidence count associated with the complex pattern, wherein the coincidence counts are adapted for determining at least one flow statistic.

A method is provided for producing motif-specific, context-independent antibodies which recognize a plurality of peptides or proteins within a genome that contain the same motif. The method includes the step of immunizing a host with a degenerate peptide library antigen featuring (i) a fixed target motif containing one or more invariant amino acids including at least one modified amino acid, and (ii) a plurality of degenerate amino adds flanking the motif. Motif-specific, context-independent antibodies produced by the disclosed method are also provided. The method encompasses motifs consisting of a single modified amino acid, as well as short motifs comprising multiple invariant amino acids including one or more modified amino acids, such as all or part of kinase consensus substrate motifs, protein-protein binding motifs, or other cell signaling motifs. Methods of using the antibodies, e.g. for genome-wide profiling, are also provided.
摘要:
A method and apparatus for engine piston installation in which robots are used for the entire engine piston installation process. A first robot equipped with a stuffing gripper and force control picks up a piston with a connection rod, detects the piston ring presence, squeeze the rings, find the engine cylinder bore, and stuffs the piston into the cylinder bore. A second robot can be used to load and unload the engine block, hold the block and position it to the location, and indexes the crankshaft into the proper orientation for each cylinder bore. A set of tools either fixed on a stationary station or on a third robot is used to guide the piston connecting rod, transport and place on the connecting rod cap, and fasten the cap onto the connecting rod. The piston connecting rod guiding process may be omitted in piston stuffing for some types of engines.
摘要:
One approach to treating individuals infected with HIV-1 is to administer to such individuals compounds that directly interfere with and intervene in the machinery by which HIV-1 replicates itself within human cells. Although the specific role of HIV-1 viral protein Vif in the viral life cycle is not known, the vif gene is essential for the pathogenic replication of lentiviruses in vivo. The present invention relates to a method for treating an individual exposed to or infected with HIV-1. Individuals identified as being exposed to or infected by HIV-1 are administered a therapeutically effective amount of one or more compounds that inhibit or prevent replication of said HIV-1 by interfering with the replicative or other essential functions of HIV-1 viral protein Vif by interactively blocking the multimerization domain of Vif, thereby preventing multimerization of Vif protein, which is important for Vif function in the lentivirus life cycle. In preferred embodiments, the compound or compounds that interactively block the multimerization domain of Vif are Vif antagonists. Pharmaceutical compositions comprising these compounds are also disclosed.
