摘要:
in a method and a device for placing units, such as motes, for executing an application in a distributed system, a placement of the units by a service layer and a communication between the units by a communication layer are provided. One field of application is for example process automation, such as in industrial or building management installations. Such installations have sensors and actuators with communication interfaces. The method and the device allow the energy demand of the installation to be reduced. Communication is preferably performed wirelessly. Network management is for example conducted according to the wireless HART protocol.

摘要:
A lithographic method for the generation of nanostructures on surfaces, characterized in that either stabilized nanometer-sized transition metal clusters or colloids of metals of groups 4, 5, 6, 7, 8, 9, 10, 11 or 12 of the Periodic Table, their stabilized metal oxide or metal sulfide analogues, polynuclear metal carbonyl clusters having stoichiometrically defined compositions, or polynuclear metal clusters having stoichiometrically defined compositions or having bridges consisting of main group elements, respectively in the form of a solution, are coated on a surface as a film which is imagewise exposed with an electron beam, wherein defined structures in the nanometer range are generated on the surface after washing off the unexposed portions of the film, optionally followed by annealing.
摘要:
A measuring element which has been lengthening in the flow direction to provide a detachment zone which is shifted downstream from the region of the measuring resistor, so that end flow disturbances no longer affect the region of the measuring resistor, and adulteration of the measurement values is prevented. The measuring element is especially suitable for determining the throughput or flow rate of the aspirated air of mixture-compressing internal combustion engines.
摘要:
The invention relates to lithium-2-methoxy-1,1,2,2-tetrafluoro-ethanesulfonate, to the use thereof as conductive salt in lithium-based energy accumulators, and ionic liquids comprising 2-methoxy-1,1,2,2-tetrafluoro-ethanesulfonate as an anion.
摘要:
A method for communicating between an electric vehicle and a charging station for electrically charging at least one energy storage device of the electric vehicle. The electric vehicle is connected to the charging station during the charging process by a lockable mechanical coupling between a terminal of charging cable connected to the vehicle and a terminal of the charging station. Charging current is fed from the charging station through the charging cable. Information is transferred in the course of the charging process based on a communication between the electric vehicle and the charging station. The information includes a signal transmitted from the electric vehicle to the charging station for locking and/or unlocking the mechanical coupling. The signal triggers the locking and/or unlocking of the mechanical coupling between the terminal of the charging cable and the terminal at the charging station.
