A modular computer system includes: a housing; at least one container; a data connection; and a housing cover. The at least one container in a lowered state is configured to be connected to a motherboard of the computer system via at least one data connection installed on the outside of the at least one container. The data connection is for exchanging data between pluggable circuit boards in the at least one container and the motherboard of the computer system while the at least one container is in the lowered state. The housing cover is configured to be fixed on the housing. A container holding device is installed on the housing cover, wherein the container holding device is configured to exert a force on the at least one container to fix the at least one container in a shakeproof manner in the housing after the housing cover has been fixed on the housing.

Shakeproof modular computer system

A test bench for a control system for controlling a wideband lambda sensor, which is configured to calculate an actual value, which represents an oxygen concentration in a measuring gap of a wideband lambda sensor or an indicator value from which the oxygen concentration can be derived, with consideration of a current generated by a pump voltage in an electrical circuit. In order to simulate the electrical response of a pump cell of the wideband lambda sensor, a first diode and a second diode are connected in parallel in the electrical circuit such that a current flows through the first diode at a first polarity of the pump voltage and a current flows through the second diode at a second polarity of the pump voltage.

An apparatus for testing an electrical component, having a simulation unit for producing a simulation signal, a plurality of test units, and at least one electrical connecting device, whereby the simulation unit and the plurality of test units are connected or connectable to each other in an electrically conductive fashion via the at least one connecting device, and the at least one connecting device has at least one electrical switch device, which is situated to make or break an electrical connection between the plurality of test units.

Apparatus having simulation unit for producing simulation signal for testing an electrical component

A method for implementing an adaptive interface between at least one FPGA with at least one FPGA application and at least one I/O module, which are designed as the corresponding sender side or receiver side, for connection to the FPGA, whereby a serial interface is formed between the at least one FPGA and the at least one I/O module, comprising the steps of configuring a maximum number of registers to be transmitted for each FPGA application, configuring a shared, fixed register width for all registers, setting an enable signal on the sender side for the registers to be transmitted out of the maximum number of registers to be transmitted, transmitting the enable signal from the sender side to the receiver side, and transmitting the registers, for which the enable signal is set, from the sender side to the receiver side.

An apparatus for measuring electrical variables includes an external measuring connection, and a converter that converts a plurality of measurement variables into respective electrical measurement variables of a single predefined type. A control device for controlling the converter is provided and at least one type of variable to be measured with the converter can be selected via the control device, and a converter for at least two types of variables to be measured respectively has at least one independent input stage that can be used to detect the measurement variable of the type to be measured and to convert it into a predefined or predefinable type of variable. An electrical signal provided at the measuring connection is analysed in a parallel manner with respect to at least two different criteria via at least two input stages for different types of variables to be measured.

Device and method for measuring and/or generating electrical variables

A device for testing an electrical component is provided, having a simulation device for generating a simulation signal, a testing device for connecting the electrical component, at least two connecting devices, and a selection device for selecting the connecting device, wherein the simulation device and the testing device can be connected in an electrically conducting manner to at least one of the connecting devices by the selection device and the individual connecting devices differ from one another in at least one electrical property. Thus, a device for testing an electrical component is provided with which in a simple manner the testing accuracy can be increased by minimizing the signal corruption due to a parasitic property of the connecting device.
