Abstract: The invention relates to a contact device for being arranged on an electrically driven vehicle, in particular electric bus or the like, or on a charging station for an electrically driven vehicle having at least two contact bar arrangements (10), each comprising one contact bar carrier (11) and at least one contact bar (12) which is disposed on the contact bar carrier and which is electrically connectable to a charging contact of a charging contact carrier of a charging contact device of the charging station or to a contact bar of the vehicle, the contact bar having a connecting device (13) for connecting the contact bar to an electrical conductor (14), which is guidable towards the vehicle or towards the charging station, the connecting device comprising a groove (15), which extends longitudinally in the contact bar, and a connecting element (16), which is attached to the groove, for being connected to the electrical conductor.

Abstract: Embodiments of the present invention are directed to a system for exchanging data utilizing Remote Direct Memory Access. In response to a system call, a Network File System component generates a file request. An External Data Representation component formats the file request and passes the request to a Remote Procedure Call component which initiates the file request with a remote computer system. The Remote Procedure Call is passed to a unifying layer which communicates the the Remote Procedure Call to various transport layer Remote Direct Memory Access implementations. The various Remote Direct Memory Access implementations are used to exchange the data in order to communicate the file request.
