Abstract: A coupling includes first and second housings, a valve element, and a guide link. The first housing is rotatable relative to the second housing. The first housing has helical cam slots and the second housing has linear cam tracks. The guide link is in the first housing and is fixed with the valve element. The guide link carries cam rollers. The cam rollers ride in the helical slots and the linear cam tracks. Rotation of the first housing causes rotation of the helical slots. The rotation of the helical slots induces the cam rollers to travel along the helical slots and along the linear cam tracks such that the guide link translates linearly. The valve element moves with the guide link between open and closed positions.

Abstract: According to an embodiment of the present invention, a federated context collaboration architecture comprises: a context store that stores contexts consumed and produced by participants, where a context represents a description of a dataset that provides a consistent flexible and technology independent mechanism for referencing data; each context comprises a context key; a context state and a context class; a context producer interface programmed to: define and reference datasets, data exchange, and data dependencies associated with each context; a context engine coupled to the context database and the context producer interface to communicate at least the state of data, data lineage and dependencies of data used to integrate and coordinate processes across different domains and infrastructures; a method for optimized selective priming of testing environments based on datasets necessary and sufficient for designated test suite; and a communication interface that communicates a defined metadata profile of each
