Abstract: The embodiments relate to a near field communication system including a plurality of near field communication devices which communicate with each other via a radio interface. During generation of a common cryptographic key between the near field communication devices of the near field communication system, at least one of the two near field communication devices monitors during generation of the cryptographic key via the radio interface in a generation period whether an additional near field communication device which could be a potential active attacker communicates with one of the near field communication devices via the radio interface. If such a suspicious type of communication is detected, generation of the common cryptographic key is optionally terminated.

Abstract: A non-track-bound vehicle operates on a route electrified by an overhead contact system. The vehicle has a current collector for energy transfer between the vehicle and an overhead cable. It has a lowering mechanism for the transfer of the current collector from an upright operational position in which the current collector is in sliding contact with the contact wires into a lowered neutral position in which the current collector is arranged within a vehicle clearance profile. An actuating element is provided for the simultaneous activation of the lowering mechanism and an additional vehicle device. The activation of the actuating element is intended in a driving situation requiring the lowering of the current collector. The operation of non-track-bound vehicles is safer even in critical driving situations, such as for example, maneuvers to avoid or overtake other vehicles at high speed.

Abstract: A method for storing and propagating error information in computer programs, in which a globally valid error variable is used for storing and propagating the error information, wherein for each recognized error a nonzero value for the error is added to the error variable as error information with a respective stipulated arithmetic sign, and wherein the value is formed from a discrepancy in the content of a coded variable from an expected value. This combination and integration of a separate global propagation variable with values derived from an error, particularly by virtue of detected discrepancies in the known error recognition and propagation paths using operations and operands in “coded processing”, achieves an increased propagation certainty.
