A hardware architecture for an artificial neural network ANN. The ANN includes a consecutive series made up of an input layer, multiple processing layers, and an output layer. Each layer maps a set of input variables onto a set of output variables, and output variables of the input layer and of each processing layer are input variables of the particular layer that follows in the series. The hardware architecture includes a plurality of processing units. The implementation of each layer is split among at least two of the processing units, and at least one resettable switch-off device is provided via which at least one processing unit is selectively deactivatable, independently of the input variables supplied to it, in such a way that at least one further processing unit remains activated in all layers whose implementation is contributed to by this processing unit.

A method for acoustically sensing an area is described. An acoustic transmit pulse is transmitted into the area by an acoustic transducer and a received signal is acquired with the aid of the transducer, in order to receive the transmit pulse reflected back from the area. Within a post-pulse oscillation time of the transducer, which directly follows the emission of the transmit pulse, the actual phase response of the received signal is determined. In the event the actual phase response deviates from a predefined setpoint phase response, an object is detected within the area. Also described is a device for acoustically sensing an area, which is designed to carry out the method.

A method for synchronizing two communication networks of an electronic data-processing system, each of the networks including one or more respective nodes, may include establishing for each of the networks a respective time schedule that establishes at least one respective time slot for a respective synchronization message. The synchronization message time slots are established to coincide. The synchronization message of the first communication network is generated by one of the nodes of the first communication network. The synchronization message of the second communication network is generated as a function of the synchronization message of the first communication network.

Synchronization of two communication networks of an electronic data-processing system

A method for transferring data between a data transmission system and a processor of a participant in the data transmission system. All components of the data transmission system are synchronized to a common global time base. The operating system time base of the participant processor is synchronized to the global time base of the data transmission system at least prior to a data transfer, and, to this end, a synchronization clock pulse that is synchronous to the global time base of the data transmission system is provided for synchronizing the operating system time base. This synchronization clock pulse may be provided by a hardware and/or software arrangement. In a data transmission system for implementing the method, the synchronization clock pulse is provided by suitable arrangement(s) of the communications controller and applied to the host processor via a synchronization line.

A supply line structure for supplying energy to electrical components of a motor vehicle, and for the transmission of information between at least a portion of the components (so-called Powerline Communications). To improve the channel characteristics of the information transmission via the supply line structure, it is proposed that the supply lines be arranged in a star configuration having at least one star point, the or each star point an impedance which corresponds to the characteristic impedance of the individual supply line branches running into it.

The series resistor is preferably configured as a ferrite sleeve.

A system for the wireless transmission of information and energy between a removable vehicle seat and the vehicle body, in which the vehicle seat is detected by measuring the inductance. In this connection, the period of an oscillating circuit is determined, in which the winding of the primary side, and thus the inductance, is connected. In this context, the frequency of the resonance voltage is determined as a function of time. In this context, the zero crossings of the resonance voltage is measured. Alternatively, the secondary side impedance is additionally measured on the primary side by a forced oscillation, namely by a voltage decay in a resonance circuit in which the winding is connected as inductance. A monitoring of the performance reliability of a firing pellet is thereby implemented.
