Abstract: A computer-implemented method for simulating a system of at least two computing systems connected via at least one data packet connection, wherein a computing system comprises interconnect adapters for physical connections based on a physical layer protocol each. A packet switching component is provided, as are physical attachments for each interconnect adapter. The physical attachments are registered. A connection director is provided for managing the data packet exchange. In response to the receipt of a simulation start indicator, each physical attachment registers its unique address at the package switching component. This assigns unique identifiers for each computing system, and unique identifiers for simulated physical layer protocols.

Abstract: An operator control device with push buttons (1), in particular a remote key fob for motor vehicles. The operator control device comprises a housing and at least one push button (1), which is mounted in the housing in such a way that it can move between stops (2, 8), and which penetrates a cutout in the housing. The cutout is defined by an edge (6), wherein the edge (6) extends into the interior of the housing with at least one section.
