  • Patent number: 12153971
    Abstract: Disclosed is an execution information sharing system that duplicates execution information to a provider target (and other targets) as it is being loaded to a consumer target. A first log information object and a second log information object are generated. The first and second log information objects comprise information indicating a consumer target and information indicating a provider target respectively where execution information generated by an application shared with a consumer account of a data exchange is written. A first event unloader and a second event unloader are generated based on the first and second log information objects respectively, wherein the first and second event unloaders are both linked to the application using a mapping. In response to receiving execution information from the application, the execution information is forwarded to the consumer target and the provider target using the first event unloader and the second event unloader respectively.

  • Patent number: 7662002
    Abstract: Discrete portions of a carbon fiber tow, selected from a group of tows, ranging in number of fibers from about 1,000 to about 150,000, and terminated by discrete contact portions of a metal conductor within a non-metallic termination assembly formed by the joinder of a cradle and a cap defining opposing parallel clamping surfaces receiving the tow portions and the contact portions in crossing engagement therebetween. Opposing energy directors on the cradle and cap serve as temporary guide rails for positioning the carbon fiber portions before and during assembly. Meltdown of the energy directors during a pressure and ultrasonic welding cycle enable self-leveling of the carbon fiber portions whereby uniform distribution of carbon fiber over the entire cross section of each of the carbon fiber portions of the assembly may be attained. The clamping surfaces remain intact after welding and retain clamping integrity.

  • Patent number: 7247822
    Abstract: An electrical resistance heating element has an axially elongated flat carbon fiber tow, which includes a multiplicity of continuous axially parallel carbon filaments. The tow is sandwiched between two layers of polyester sheet material and bonded to only one of the layers. The other of the layers overlies the tow in direct contacting engagement with and unconnected relation to the tow and is connected to longitudinally extending marginal portions of the one layer along transversely opposite sides of the tow. The heating element may be produced by a continuous forming process.

  • Patent number: 6017238
    Abstract: A patch cord assembly for plugging connection with an in-line array of insulation displacement connectors (IDC's) on a 110 cross-connect panel includes a plugging connector defining a plurality of plug receptacles separated from each other by contact supporting walls. Each supporting wall supports an associated elongated contact which defines a portion of the wall and has elongated contact surfaces exposed at opposite sides of the wall.

  • Patent number: 5556307
    Abstract: A field terminable modular telecommunications jack assembly includes a modular jack containing a plurality of spring wire contact members mounted in cantilever position and configured to cooperate with an industry standard modular plug to minimize the length of circuit paths through the jack. Double ended insulation displacement connectors connected to fixed end portions of the spring wire contact members and projecting from the jack cooperate in plugging engagement with insulated solid wire conductors terminated by a field terminable coupling and compensating member which facilitates field termination of the jack. The solid wire conductors terminated by the coupling and compensating member are arranged within the compensating and coupling member to cancel signal coupling within the jack assembly. The double ended insulation displacement connectors are axially aligned with both the solid wire conductors and spring wire contact members.

  • Patent number: 5425172
    Abstract: A modular telecommunication jack adapter has a front part formed by at least one standard modular telephone jack and a rear part defined by a standard modular telephone plug. The front and rear parts are connected by a coupling member which defines a rearward extension of the modular jack. A plurality of resilient unitary spring wire conductors disposed within the adapter extend between the front part and the rear part and have forward end portions which define an in-line array of moveable contacts supported in cantilever position and parallel relation within the jack. The rear end portions of the resilient wire conductors are softened by annealing to receive an in-line array of spade contacts which terminate the conductors at the rear end of the plug. One or more of the conductors may be formed with a crossover formed within the connecting member.
