Abstract: A method for connecting cell outgoing conductors of a first and a second cell. Here, a connection between the first and second cell outgoing conductors is produced by means of a connecting apparatus, which includes a first and a second component. At the same time, however, the first and second components also have the function of pre-bending the cell outgoing conductor of the first and second cells, respectively, in order thus to enable a particularly low physical height of the cell outgoing conductor arrangement. A system according to the invention includes a first and a second cell, which have cell outgoing conductors that are connected and shaped in this way.

Abstract: A fluid line for transporting fuel from a pump pre-filter to a fuel pump, which damps the noises of the fuel pump and a fuel delivery unit that is equipped with said fluid line Damping is achieved by at least one damping region, which is situated opposite the intake opening and which damps vibrations originating from the fuel pump.

Abstract: A microcontroller which can be coupled to an execution unit. For the operation of the microcontroller, a program in the microcontroller generates a message as a function of input data and transmits said message to the execution unit. For the operation of the microcontroller, accompanying the message, a check code is generated as a function of the execution of the program and is transmitted to the execution unit. For the operation of the execution unit, a test determines whether the check code is logically predefined and/or received within a predetermined time interval, wherein in the case of a positive test result, the message is designated as valid, and in the case of a negative result, the message is designated as invalid.

Abstract: A delivery unit for delivering fuel in a fuel tank comprises a prefilter and swirl pot which are produced as one piece. The prefilter is produced during die-casting of the swirl pot. The invention allows the delivery unit to be produced in an especially inexpensive manner.
