Methods and systems for providing rotary position sensor information. One system includes an electronic processor configured to receive a first set of signals from a first bridge circuit of a rotary position sensor and receive a second set of signals from a second bridge circuit of the rotary position sensor. In response to the receipt of the first set of signals from the first bridge circuit stopping, the electronic processor is also configured to identify a fault associated with the first bridge circuit. The electronic processor is also configured to receive a pulse signal and determine a rotary angle based on the pulse signal and the second set of signals from the second bridge circuit. The electronic processor is configured to generate an output torque value based on the rotary angle for controlling a motor.

Providing availability of rotary position sensor information after hardware failures

A measuring device includes an integrated sensor unit. The integrated sensor unit is configured to record at least one moisture characteristic value of at least one building material. The measuring device further includes a communication unit. The communication unit is configured to receive at least one signal from at least one external sensor unit.

Measuring device, especially moisture measuring device

A device safety apparatus, in particular a hand-held device safety apparatus, having an antenna unit having at least one antenna element, which is provided for the purpose of transmitting and/or receiving a safety signal. The antenna unit has at least one additional component, which in conjunction with the antenna element is provided to specify a safety zone.

Device safety apparatus

A method for managing a plurality of devices interconnected as a communications network in a motor vehicle via one or a plurality of interconnected bus systems is presented, the method including recognizing and generating a device specific control component for newly attached devices. The method includes operating a generic control module to operate upon data stored in a newly attached device to generate the device-specific control component, which is used to control the device. The device-specific control component either can be added to the generic control module or can be stored independently of the generic control module in the respective device. The generic control module is used in a gateway or a system manager of the communications network. A human-machine interface adapts to the device-specific control component. The network is interconnected by a bus system, preferably embodied according to IEEE 1394.

Method for controlling devices, and a device in a communications network in a motor vehicle

A computer system for vehicles is provided in which the functions are partitioned among the computers of the computer system. A first computer takes over the driving-related functions, while a second computer having greater computing power takes over entertainment-specific functions.

Computer system for use in vehicles

A machine-tool safety device for a machine tool having a transmitting unit for transmitting an outgoing signal and a receiving unit for receiving an incoming signal. The machine-tool safety device has an adjusting unit for at least semi-automatically adjusting the outgoing signal to be transmitted.

Machine-tool safety device

A method for synchronized transmission of audio data streams in a bus system, for example, based on the IEEE 1394 Standard, and a circuit system for performing said method including at least one data source and at least one data sink. The data source includes at least one clock or timer unit and at least one generator unit. The generator unit is connected to the clock or timer unit and receives at least one data frequency.

Circuit arrangement and method for synchronised transmission of audio data streams in a bus system

A method for testing a network made up of network nodes and devices connected to network nodes, includes: determining the network topology, using at least the network topology, using at least the number of network nodes, the network-node identity, and the wiring of the network-node inputs and outputs; and comparing a current network topology to a permanently stored, reference network topology for the network, in order to detect a change in the number and/or type of devices connected to the network, in the number and/or type of network topology, and/or in the number and/or type of network nodes at which a change is present.

Method for testing a network, and corresponding network

A method of operating a device which is connected to a vehicle communications network is described, a switched-off device being reactivated by the bus manager via a frequency pulse transmitted over a power supply line. The device may be switched off by the bus manager or by itself if there is no data communication with the device for a predetermined period of time. The frequency pulse is analyzed by an analyzer circuit of the switched-off device, the analyzer circuit having a frequency-selective filter and a threshold detector. The frequency pulse may be transmitted at a frequency which is valid for only one device or at a frequency for a group of devices or at a frequency for all devices. If the devices are arranged in branches, then all the devices downstream from a switched-off device are also switched off or reactivated.

Method,device and bus manager for operating a device that is connected to a motor vehicle communications network

A method for controlling the sensitivity of at least one microphone in which video data of a sound source, in particular a speech source, is recorded by a camera. The camera is located in a predetermined position relative to the at least one microphone. A position of the sound source relative to the at least one microphone is determined as a function of the recorded video data and/or a focus setting of a lens of the camera. The sensitivity of the at least one microphone is adjusted as a function of the determined position.

Method for controlling the sensitivity of a microphone

A vehicle computer arrangement, particularly for a motor vehicle, a train, an airplane or a ship, which is provided with at least two computers ( ) and at least one data bus ( ) via which the at least two computers ( ) are interconnected, and in which at least one monitoring circuit ( ) is arranged between a first computer ( ) and a second computer ( ) of the at least two computers, the monitoring circuit checking whether a data exchange between the first and the second computer is permitted for data processed or to be processed in the first or the second computer, and blocking the data exchange in the event that it is not permitted for the monitored data.
