Abstract: Methods and apparatuses, including computer program products, are described for policing and prioritizing of data services. Each packet in a data stream is directed to a substream policer of a plurality of substream policers. Each packet is allowed through the substream policer based on rate parameters associated with the substream policer. The packets allowed by the substream policer are directed to an aggregate policer. Each packet allowed through the substream policer is allowed through the aggregate policer based on rate parameters associated with the aggregate policer. The substream policer and the aggregate policer are charged for each packet allowed by both the substream policer and the aggregate policer. The substream policer and the aggregate policer are not charged for each packet not allowed by either the substream policer or the aggregate policer.

Abstract: Many pathogens, including Mycobacterium tuberculosis and Yersinia pestis, rely on an iron acquisition system based on siderophores, secreted iron-chelating compounds with extremely high Fe(III) affinity. The compounds of the invention are inhibitors of domain salicylation enzymes, which catalyze the salicylation of an aroyl carrier protein (ArCP) domain to form a salicyl-ArCP domain thioester intermediate via a two-step reaction. The compounds include the intermediate mimic 5?-O—[N-(salicyl)sulfamoyl]-adenosine (salicyl-AMS) and analogs thereof. These compounds are inhibitors of the salicylate activity of MbtA, YbtE, PchD, and other domain salicylation enzymes involved in the biosynthesis of siderophores. Therefore, these compounds may be used in the treatment of infection caused by microorganisms which rely on siderphore-based iron acquisition systems.

Abstract: Described are computer-based methods and apparatuses, including computer program products, for packet signaling content control on a network. The content control includes two sets of filters—an ingress filter set and an egress filter set. For packets coming into an internal network, the packets (e.g., SIP packets) are filtered by an ingress filter associated with the external network and which determines whether to discard sets of information from the packet description information (e.g., a header, an optional header). The packet is also filtered by an egress filter associated with the internal network and which determines whether to discard sets of information from the packet description information. The packet is transmitted to the internal network. For packets leaving the internal network, the filtering occurs in the opposite direction (e.g., egress filter associated with the internal network and then ingress filter associated with the external network).

Abstract: A system and method for generating power. The system has a first electrode member comprising a first region and a second electrode member comprising a second region. Preferably, the second electrode member is coupled to the first electrode member. An electret is coupled between the first electrode member and the second electrode member. The system has a spatial region provided between the first region of the first electrode member and the second region of the second electrode member. A volume of fluid (e.g., liquid, liquid and solids, gas and liquid, solids and gases) is provided between the first region and the second region and is adapted to move between the first region and the second region to cause a change in an electric field characteristic within a portion of the spatial region by the movement of at least a portion of the fluid within the portion of the spatial region to generate a change in voltage potential between the first electrode and the second electrode.

Abstract: A bit retainer system includes a bit having a head and a shank, a driver sub disposed around the shank of the bit and adapted to engage a hammer case, a bit retainer disposed around the shank of the bit and abutting an upper end of the driver sub, wherein the bit retainer includes a split ring with a circumferential groove, and a secondary retainer disposed around the bit retainer, wherein the secondary retainer includes a snap ring configured to engage the circumferential groove.

Abstract: Method and apparatus for neighbor and edge indexing is described. A vertex is identified and assigned a reference. One-ring neighbor vertices of the vertex are identified. The reference is assigned to each of the one-ring neighbor vertices identified. An index to one of the one-ring neighbor vertices is assigned. The index is successively incremented to provide indices for each of the one-ring neighbor vertices remaining. Edge indexing follows as described above, with the vertex and its one-ring neighbors defining end points of edges. Additionally, offset indexing is described, and may be used for a consistent order of computation.

Abstract: Method and apparatus for generating a primitive extension defining a generalized primitive is described. The primitive extension defines the connectivity and vertices used to specify a collection of connected primitives, such as a strip-type or fan-type generalized primitive. A generalized primitive includes a number of vertices where some of the vertices are shared with neighboring primitives. The primitive extension includes an originating primitive, vertex data, and connectivity information. The primitive extension provides a general interface for describing a variety of connected primitives.

Abstract: A fixed function engine and method are described for processing a set of primitive commands. One embodiment of the fixed function engine includes a means for receiving one or more primitive commands, where each such primitive command includes information for processing vertex data using a user-developed program or subroutine. The fixed function engine also includes a means for determining a set of related primitive commands from the received primitive commands and a means for identifying a first primitive command to process from that set. In addition, the fixed function engine includes a means for transmitting a first program command, which is related to the first primitive command, to a processing engine for processing.

Abstract: A programmable geometry engine is described. One embodiment of the programmable geometry engine includes a programmable primitive engine configured to receive primitive commands that include information for processing vertex data using user-developed programs or subroutines. The programmable primitive engine also is configured to transmit program commands that include program pointers and data pointers. In addition, the programmable geometry engine includes a processing engine configured to receive the program commands. The processing engine is further configured to retrieve the user-developed programs or subroutines using the program pointers and to retrieve vertex data using the data pointers. Also, the processing engine is configured to process the vertex data based on instructions included in the user-developed programs or subroutines to produce processed vertex data and to transmit results to the programmable primitive engine.
