Abstract: An electrical device includes a housing, a circuit board including at least one fastening means, at least one fastening element configured to fix the circuit board on the housing by the at least one fastening means, and a microcontroller arranged on the circuit board, wherein an electrical contact electrically connected to the microcontroller is arranged on the circuit board to be spaced apart from the fastening means by a specified spacing, the fastening element has a housing-specific diameter at an end facing the circuit board, and the microcontroller is configured to determine a type of the housing on the basis of whether the fastening element contacts the at least one electrical contact.

Abstract: A computer system comprising a CPU, a data bus, components and a communication module for the administration of the CPU or components. The communication module comprises a data interface coupled to the data bus of the computer system. The user interface comprises a display unit and a control panel. A control unit is coupled to the user interface and the data interface for transmitting data to and from the CPU or components using the data bus. A memory is provided for the storage of configuration parameters and status information, which is coupled to the control unit via a memory bus. The communication module is adapted for obtaining system information of the components without using the CPU of the computer system and performing a configuration of the components using the configuration parameters.

Abstract: A cooling device for an electric machine with thermal zones having interactions with one another is proposed, each of the thermal zones containing a heat source and a temperature sensor, and at least one cooling means, a controlling element connected to the temperature sensor being allocated to each thermal zone for activation of the at least one cooling means. The cooling device is characterized by the fact that outputs of a plurality of controlling elements can be connected to the at least one cooling means. In an inventive cooling device, a plurality of controlling elements can act on one or more cooling means, whereby cooling means are supported or completely replaced by other existing cooling means.

Abstract: A method for protecting a computer system (1) having a choice of various users (3, 4) with various authorizations (3a, 4a), having at least one interface (2) for interchanging data with at least one internal or external peripheral device (5), where the interface (2) is active when the peripheral device (5) has authorization or when the authorization (3a, 4a) of the current user (3, 4) activates the interface (2).
