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.
摘要:
The invention essentially relates to a facility for charge current control of storage units in an electrical energy supply grid including, among others, distributed generators and distributed storage units, in which a logic unit is present such that, a storage charge current value can be determined for the storage unit as a function of control variables transferred via a communication system of measurement variables determined at the storage and of locally held internal control variables. This represents an important component for achieving the optimum possible overall utilization of the distributed and multiple-use energy storage.

Disclosed is a method for the computer-aided detection and identification of copyrighted contents that are exchanged between at least two computers in a communication network, especially in peer-to-peer networks. Said method comprises the following steps: —first data packets that arc specified according to an execute command and are analyzed regarding at least one first criterion are fed to a first computer (PAT), first and second parameters being determined from the data packets meeting the at least one first criterion; —the first computer (PMT) determines the first data packets encompassing the second parameter from all first data packets that are fed to the first computer (PAT) and transmits said data packets to a second computer (FP); —a third computer (CRAW) sends at least one inquiry message for detecting data with copyrighted contents to the communication network, said third computer (CRAW) receives reply messages in reaction to the at least one inquiry message and requests second data packets meeting at least one second criterion from the communication network and analyzes the same, third and fourth parameters being determined from the data packets meeting the at least one second criterion; —the third computer (CRAW) determines the second data packets encompassing the fourth parameter from all second data packets that are fed to the third computer (CRAW) and transmits said data packets to the second computer (FP); —the first computer (PAT) transmits the first parameters to the third computer (CRAW) in order for said first parameters to be used in the second criteria; and—the computer (CRAW) transmits the third parameters to the second computer (PAT) in order for said third parameters to be used in the first criteria.
摘要:
A reciprocating internal-combustion engine having at least two gas intake ports (3) with gas intake valves (6), at least one gas exhaust port (4) with a gas exhaust valve (7) and at least one ignition device (14) per cylinder (1) is provided. The engine can also include a combustion chamber (1.1) formed by a cylinder cover (2.1) and a crown (11.1) of a piston (11). A trough-shaped recess (12) can be provided in the piston crown (11.1) and is bounded by a trough base (12.1) and side walls (16). The recess (12) can intersect a roof ridge (11.2) on the piston crown (11.1) and the trough base (12.1) slopes towards a fuel injection nozzle (8) and ends in a wall zone (12.2) extending steeply upwards on its side facing the fuel injection nozzle (8).
