摘要： Systems and methods for simulating gas flow dynamics of a real hydrogen fuel cell system using a computer, wherein the real hydrogen fuel cell system includes a gas container volume network having gas container volumes interconnected by gas transport lines. The method includes defining volume element and flow channel classes, defining a plurality of volume instances and a plurality of flow channel instances, for each flow channel instance, creating a first interconnection representation that defines a source container volume and a destination container volume for the flow channel instance, wherein the first interconnection representation mimics a portion of the gas container volume network of the real hydrogen fuel cell system, and simulating, using the first interconnection representation, a thermodynamic state for each of the volume instances, the thermodynamic state representing thermodynamic parameter(s) in each container volume of the gas container volume network of the real hydrogen fuel cell system.

摘要： To program a first programmable gate array, for example a first FPGA, in a distributed computer system, a configuration of a first configuration logic on the first programmable gate array is provided. The first configuration logic is configured to receive a first user bitstream from a configuration software for configuring a first user logic on the first programmable gate array and to store the first user bitstream on a non-volatile memory of the first programmable gate array for the purpose of subsequently configuring a first user logic on the first programmable gate array according to the specifications from the first user bitstream. In an expansion stage of the invention, a configuration of a programming logic on the first programmable gate array is also provided for programming a second programmable gate array, which is connected to the first programmable gate array to form a daisy chain.

摘要： A method of reducing training data via a system having an encoder, wherein at least a portion of the training data forms a temporal sequence and is combined into a first set of training data, and the encoder maps input data to prototype feature vectors of a set of prototype feature vectors. A first input datum is received from the first set of training data, and propagated by the encoder. The input datum is assigned one or more feature vectors by the encoder, and depending on the assigned feature vectors, a defined set of prototype feature vectors is determined and assigned to the first input datum. An aggregated vector is created for the first input datum. A second aggregated vector is created for the second input datum and the first and second aggregated vectors are compared and a measure of similarity for the aggregated vectors is determined.

摘要： A testing device for testing a distance sensor includes a receiving element for receiving an electromagnetic free-space wave as a receive signal, and a radiating element for radiating a simulated reflection signal. The receive signal or a signal derived therefrom is routed via a time delay circuit, and is thus time-delayed to a time-delayed signal. The time-delayed signal or a signal derived therefrom is radiated as the simulated reflection signal. The time delay circuit has an analog delay path and a digital delay path. The analog delay path implements shorter time delays than the digital delay path, apart from a possible overlap region. An input switch is used to switch the receive signal or the signal derived therefrom to the input of the analog delay path or to the input of the digital delay path, and the signal becomes the time-delayed signal after passing through the connected delay path.

摘要： A module with a functional unit for generating a data stream with a data output for outputting the data stream to a serialization unit provided for receiving a data stream from a serialization unit of a first series. A serialization unit of a second series is set up to serialize the data stream and output it through the data output, and a configuration data input receives configuration data defining a first register configuration of a serialization unit. A mapping of register addresses of the serialization unit of the first series to register addresses of the serialization unit of the second series can be stored in a data memory of the module. The configuration unit is set up to read in the configuration data, to use the mapping, and to configure the registers of the serialization unit of the second series according to the configuration of the second register.

摘要： A computer-implemented method for real-time simulation of the operation of a specific electric motor by a simulator arithmetic unit comprising a programmable logic device on which a generic motor model is implemented. The method includes: providing a generic system of equations corresponding to the generic motor model; receiving specific information corresponding to the specific motor to be simulated for the generic system of equations and inputting this information into the generic system of equations; generating a specific library containing at least some of the arithmetic operations required for the matrix operations for calculating the operation of the specific motor; implementing references in the generic motor model to the arithmetic operations of the specific library required for real-time simulation of the operation of the specific electric motor; and simulating the operation of the specific electric motor by running the generic motor model on the simulator arithmetic unit.

摘要： A method for planning the design of partitions for a programmable gate array comprising different types of logic blocks of predetermined position, and a plurality of program routines comprising at least one first program routine and at least one further program routine. A mapping of a first partition of the programmable gate array with the first program routine and at least one further partition of the programmable gate array with the at least one further program routine is performed. The need of the first program routine for the individual types of logic blocks is determined. Meeting this need with the logic block resources of corresponding type available in the first partition. At least one logic block of corresponding type from the further partition or at least one of the further partitions into the first partition is transferred.

摘要： A method for semi-automated development data management for control devices includes saving a development data model in a central data store comprising a plurality of mutually related configuration data units, wherein the configuration data units each store control commands and/or configuration parameters. The method further includes providing a ruleset and identifying an initial configuration data unit, wherein it is possible, using the ruleset, to identify further configuration data units automatically on a basis of a relationship thereof with the initial configuration data unit. In addition, the method includes applying the provided ruleset to the development data model in order to identify a subset of configuration data units within the development data model and saving the identified subset.

摘要： 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.
