A method for making a communication available between data modules that are interconnected via communication units of a device for making the communication available, in which at least one data module is automatically selected by at least one communication unit via a data protocol.

Method for making a communication available

A method for determining angular position, which removes a systematic error in the angular position determination and requires a low calculating effort, by determining a first factor and a second factor as a function of an angular position, forming a first product from a first signal and the first factor, and a second product of the second signal and the second factor, forming a subtraction result by the subtraction of the second product from the first product, and comparing the subtraction result to a quantity.

Method and device for determining angular position

A method of supporting the optimization of a test program that is made up of a plurality of actions is described. The method may include applying the test program to a device, recording a protocol having a plurality of entries, each corresponding to an action and each specifying at least the type and the time the action is performed, outputting a graphic representation of the sequence of the actions derived from the protocol highlighting at least one selected type of action performed during the application of the test program.

Method and device for optimising a test programme

A system for wireless data transmission between a stationary transmitting/reception device and a rotating body, e.g., a vehicle wheel, having secondary antennas, is provided. A plurality of stationary primary antennas are coupled to the stationary transmitting/reception device, and a plurality of secondary antennas are positioned along a circumference of the rotating body. Amongst the plurality of primary antennas, at least one primary antenna is provided for transmitting electrical energy to the secondary antennas, and at least one other primary antenna is provided for communications with the secondary antennas. In this manner, data transmission independent of the speed of the rotating body and the position of the secondary antennas is achieved.

HF wheel rim antenna having several patch antennas

An apparatus, a tire, a transmitting and/or receiving device and a system for the wireless transmission of data are proposed, the apparatus being connected to a rotatable part, the part having a metal belt, the apparatus having an antenna device which is provided in a manner that it is able to be coupled inductively and/or capacitively to the metal belt.

Apparatus for transmitting and/or receiving data, tire for a motor vehicle, transmitting and/or receiving device and system for the wireless transmission of data

A harmonically damped oscillator circuit including a controllable oscillator amplifier for generating an oscillator output signal and including an amplitude control circuit for controlling the amplitude A of the oscillator output signal, an amplitude control signal V being generated by the amplitude control circuit as a function of a determined amplitude A of the oscillator output signal in such a manner that the oscillator amplifier functions in a predefined operating range having an approximately linear amplification characteristic with a definable, small amplitude at a preset operating point, and the oscillator amplifier being designed in such a manner that the predefined operating range and the preset operating point are independent of the amplitude control signal V . Thus, a stable amplitude loop for producing a low-distortion oscillator output signal can be achieved also under consideration of a comparatively large scatter range of the used component characteristics and parameters. The oscillator circuit can, therefore, be effectively produced as an integrated circuit.
