  • Patent number: 7694344
    Abstract: A method and system is disclosed for enhancing network security by using a service entry stack in a distributed computer network. After an event system receives an indication for a publisher to publish a first event to a subscriber list of one or more event subscribers, authorization concerns are examined for publishing the first event to each event subscriber by sequentially examining each event subscriber in the subscriber list. When publishing the first event to the event subscriber, a service entry stack is utilized for recording event execution information and process hierarchy of the distributed computer network so that such information can be used for enhancing the security of the distributed computer network.

  • Publication number: 20070241078
    Abstract: Methods and apparatuses for releasably attaching support members to microfeature workpieces to support members are disclosed herein. In one embodiment, for example, a method for processing a microfeature workpiece including a plurality of microelectronic dies comprises forming discrete blocks of material at a first side of a support member.

  • Patent number: 7225617
    Abstract: A hydraulic drive apparatus having a center section located in a housing includes a hydraulic pump and motor disposed thereon and in fluid communication with a hydraulic porting system in the center section. The pump is driven by an input shaft extending out of the housing and the motor drives an output shaft that is generally perpendicular to the input shaft. A bypass actuator extends into the center section perpendicular to both the input shaft and the output shaft. Rotation of the bypass actuator acts to lift the hydraulic motor from the center section to break the hydraulic interface between the hydraulic motor and the hydraulic porting system. The center section may include a second pump and motor with a second hydraulic porting system and a second bypass actuator.

  • Patent number: 7170365
    Abstract: An ultrafast sampling system includes an interposer and a sampler that include series of Schottky diodes configured with a non-parallel waveguide to form shocklines or nonlinear transmission line (NLTLs) that produce a differential strobe pulse. The shocklines are defined by non-parallel conductors that are configured as, for example, triangular, dentate, arcuate, or other shapes, or as conductors that have edges that are triangular, dentate, arcuate, or the like. The conductors are defined with respect to a substrate, and are airbridged so that at least some portions of the conductors are displaced from the substrate to reduce waveguide capacitance. Electrical connection to the sampler is made with airline having a inner conductor that is deformable to contact an input pad defined on the sampler.

  • Publication number: 20050099030
    Abstract: An upper imperforate cap closes the uppermost end of a bailer and a lower imperforate cap closes the lowermost end of the bailer. In a preferred embodiment, screwthreads are formed in the uppermost and lowermost ends of the bailer and complemental screwthreads are formed in the upper and lower caps. By capping the opposite ends of a bailer, the bailer serves as its own container when the sample contained within it is shipped to a laboratory. This eliminates VOC devices, nozzles, and the concomitant contamination that may result from emptying a bailer in the field.

  • Patent number: 6850964
    Abstract: Methods of increasing cache capacity are provided. A method of increasing cache capacity is provided wherein original data are received in a cache with access to one or more variants of the original data being required, but the variants do not reside in the cache. Access is provided to the variants by using one or more delta data operable to be applied against the original data to produce the variants. Moreover, a method of reducing cache storage requirements is provided wherein original data and variants of the original data are identified and located within the cache. Further, delta data are produced by noting one or more differences between the original data and the variants, with the variants being purged from the cache. Furthermore, a method of producing derivatives from an original data is provided wherein the original data and variants of the original data are identified.
