Abstract: The present invention is directed to a self-sealing breakaway valve having a poppet-style design. The breakaway valve may be made from two body portions coupled together by one or more frangible fasteners in order to form a flow path through the breakaway valve. Each body portion may include a valve mechanism responsive to separation of the two body portions from each other to cause closure of the flow path in the respective body portion. The valve mechanisms may be releasably coupled together by a coupling key configured to restrict movement of each valve mechanism, so that the flow path within the breakaway valve remains open. Upon separation of the two body portions from each other, the coupling key may be released from the valve mechanisms allowing for closure of the flow path by the valve mechanisms thereby preventing fluid leakage from the breakaway valve.

Abstract: In one aspect, the invention is a tuned stub, SCSI topology comprising a SCSI bus, a breakout node on the SCSI bus, an external SCSI connector on the SCSI bus at a first point defined by a first propagation delay; an internal SCSI connector on the SCSI bus at a second point defined by a second propagation delay, the first and second propagation delays being substantially equal; a SCSI adapter electrically tapping the breakout node; and a terminator electrically tapping the breakout node.

Abstract: A method and apparatus for adding inductance is disclosed. Inductance may be added to a transmission line coupled to a printed circuit board to increase the inductance associated with a transmission line by utilizing ferromagnetic materials.

Abstract: Embodiments of the present invention may provide for high-density and high speed interconnections while maintaining reduced signal interference. In some embodiments, differential signals are organized in connectors such that differential signal pairs are orthogonal to each other. In other embodiments, differential signal tri-conductor sets may be oriented such that they are generally orthogonal to each other. The orthogonal contact organization may provide for reduced coupling between differential signals.

Abstract: A tuned stub, SCSI topology is disclosed. More particularly, a SCSI bus comprises a plurality of SCSI load stubs, a pair of SCSI terminators, a plurality of traces electrically connecting the SCSI load stubs between the SCSI terminators, and a plurality of tuning stubs. The tuning stubs are positioned at predetermined locations on the plurality of traces and have predetermined lengths such that they are capable of filtering noise on the SCSI bus.
