Abstract: A method for operating an expansion card of a computer is proposed, said computer having at least one slot for accommodating the expansion card, wherein there is stored in a memory area of the expansion card a first and a second configuration data record, one of which is assigned to a first and the other to a second signaling voltage, and wherein the configuration data records transmitted to a FPGA chip of the expansion card indicate to the FPGA chip whether a protection circuit is to be activated or deactivated. Suitable measures enable functional units of a PCI expansion card suitable for both a 3.3 V and a 5 V signaling voltage to be integrated in an FPGA together with a PCI controller, the expansion card being supplied or suppliable with an external voltage independently of a signaling voltage of a computer or basic system.

Abstract: A method for determining a combustion chamber pressure of an internal combustion engine is described, which is used for a simple and accurate correction of the determined combustion chamber pressure. For this purpose, a first time curve of the combustion chamber pressure is compared with a second time curve of the combustion chamber pressure. A correction factor is determined as a function of the comparison result. The determined combustion chamber pressure is corrected via the correction factor.

Abstract: The passenger car has a supporting structure, with at least two longitudinal members (1). The longitudinal members are joined together in the middle by means of a torsionally rigid cross-member (2) which is constructed as a large-volume tubular profile and accommodates at least parts of the transmission, while the longitudinal members (1) at the side bend upwards from a floor panel (5) and in order to increase the flexural rigidity of the longitudinal member (1) about the transverse axis, the vertical extension of longitudinal member (1) is sufficiently great that the top edge (1) is located at least at the height of the seating-surface of the driver's seat.
