Abstract: A charge coupler with integrated electrical and mechanical disconnect switching can include a first member. A charging coupler can include a first member and a second member. The second member can be coupled at a first end with the first member. A charging coupler can include a first switch disposed at the first member and operable to cause, in response to a movement of the second member to a first angle with the first member that engages the first switch, a charging device to electrically decouple the charging device from a vehicle. A charging coupler can include a second switch disposed at the first member and operable to cause, in response to a movement of the second member to a second angle with the first member that engages the second switch, the charging device to mechanically decouple the charging device from the vehicle.

Abstract: A method of providing internet access to a data object repository comprising managing data objects hosted by said repository using a generalised repository directed graph data model having object nodes and resources, said resources comprising at least one of (i) a literal; (ii) actual resource data; and/or (iii) a URI directing a request for resources to an address; wherein said object nodes comprise higher level abstractions of data objects; wherein all object nodes and resources are named, as well as all arcs between object nodes and other object nodes or resources, said arcs modelling properties of said nodes; wherein each said directed graph has a graph interface which represents data as a directed graph of nodes and resources; and wherein said graph interface is capable of enabling access to data represented by said directed graph by traversal of said directed graph using http:GET.
