Abstract: A wiring arrangement for protecting a bleed air supply system of an aircraft against overheating is associated with a bleed air supply system. The bleed air supply system includes a bleed air source, a bleed air feed, a shutoff valve arranged in the bleed air feed and a leakage monitoring device with a monitoring control device, which is connected via a shutoff circuit to the shutoff valve in such a way that the shutoff valve is closed when the shutoff circuit is interrupted. The wiring arrangement includes a thermal switch, which is connected in series with the shutoff valve and the monitoring control device to the shutoff circuit and which, once a predetermined limit temperature has been exceeded, interrupts the shutoff circuit.

Abstract: A leak detector for detecting a leak in a line includes a transmitting device for generating radiation to be coupled into the line. By a receiving device, radiation that has emerged from the line through a leak is received, as a result of which the leak becomes detectable.

Abstract: A bus station for connection to a bus system for a restraining device and/or sensor is used for muting a defective bus station or to have automatic error management carried out in the bus station, to enable the bus station to transmit properly again. For this purpose, the transmitting current and/or the power consumption of the bus station is monitored. The transmitting stage is triggered and, if appropriate, isolated from the bus station as a function of this monitoring. In a refinement a backup transmitting stage may be connected as a replacement for the defective transmitting stage.

Abstract: A bus master for a bus for connection of sensors and/or an ignition means device, which has at least two bus driver arrangements allowing data to be received independently of one another. For this purpose a polling operation, specifically using a multiplexer or a demodulator associated through one of the particular bus driver arrangements, is used. Furthermore, a state machine is provided, which also alternatingly determines the system status on the basis of the measured quantities determined on the bus conductor for the particular bus driver arrangement. In a refinement, a particular bus driver may have a dedicated processor for system status determination.

Abstract: The error-free function of modules in a bus system with a central unit is tested. First, all (error-free) modules are set into a silent operating mode in response to an agreed silence-command, and then in this silent operating mode it is tested whether all modules still remain silent, i.e. do not transmit data, in response to an agreed data request allocated to these modules. A module that nonetheless transmits data is recognized as faulty and is deactivated. Subsequently, all modules except for a module to be tested are set into the silent operating mode, and then it is tested whether this test module transmits its data in response to the agreed data requests allocated to it and remains silent in response to the data requests not allocated to it. Additionally, the position of the return-transmitted data can be determined and compared with a nominal position.

Abstract: A sensor adapted for connection to a bus and a method for supplying power to a sensor connected to a bus are described, which serve to minimize the power consumption of a sensor connected to the bus. To this end, power for a sensor is stored in an energy storage device in a first time period and is discharged in a second time period, that is, the measurement time, in order to supply the sensor element with power. A capacitor is used as the energy storage device, and the charging of the capacitor is monitored by a voltage monitoring device.

Abstract: A possibility for controlling and supplying energy to a larger number of restraint means components in a vehicle seat that can be installed in variable fashion, this possibility being able to be realized using a constructively simple and robust electrical connection, so that this connection in particular also withstands the mechanical stresses that occur during the installation and removal of the vehicle seat. For this purpose, the vehicle seat is equipped with at least one system bus for controlling and supplying energy to the individual restraint means components of the vehicle seat. In addition, means are provided for the electrical contacting of the system bus during the installation of the vehicle seat.

Abstract: A device, using which signals and energy may be transmitted without contact between an electrical device on or in the vehicle body and an electrical device on or in a vehicle seat, reliable signal and energy transmission being ensured even in the event of frequent changes of the seating configuration, without the vehicle user having to take special precautions for this purpose. The two electrical devices are each assigned a transmission module. These transmission modules form a high-frequency wireless transmission path. The transmission module on or in the vehicle body is integrated into the rail system for the vehicle seat, while the transmission module on or in the seat may be coupled into the rail system in such a way that the signal and/or energy transmission occurs via the displacement current generated in the rail system.

Abstract: The invention relates to a method for the testing of the error-free function of modules in a bus system with a central unit as well as suitable modules, a corresponding central unit and a corresponding bus system. For this purpose, an especially agreed-upon silence-command is provided, in response to which the modules in the error-free condition switch into a silent operating mode, and also expressly transmit no data particularly in response to the data requests allocated to the modules. By means of this silence-command, at first all modules can be set into the silent operating mode, and then by means of the agreed data request it can be tested whether all modules still switch into the silent operating mode. A module that nonetheless still transmits is recognized as faulty and is, for example, deactivated.

Abstract: A bus station addressable using at least one group address is provided. For the evaluation of the group addresses, the bus station has a decoder for converting a group address received via the bus into a decimal group address, a register in which the permissible group addresses are stored as a register word, and a logic circuit for the comparison of the decoding word and the register word. The logic circuit generates an enabling signal for the bus station, as a function of the comparison.

A capacitor is used as energy accumulator and charging of the capacitor is monitored by the voltage monitoring device.
