A wireless communication system for control units in a vehicle, where a Gateway controller is provided, which may be linked via a first interface to least one microcontroller of a control unit of the vehicle, and which may be connected via a second interface to a wireless communications connection, the second interface encompassing at least one interface element which allows the broadband transmission of data via the wireless communications interface.

In a measuring circuit for a capacitive sensor for distance measurement and/or space monitoring comprising sensor wire and shielding electrode, a sine signal is applied to the shielding electrode. The sensor wire is connected, via a shielded cable, with one input of an input amplifier which serves as current-voltage converter and whose supply voltage is likewise influenced by the sine signal. The output of the input amplifier is connected with one input of a phase-dependent rectifier arrangement, the sine signal is applied to the other input of the phase-dependent rectifier arrangement, and its output is connected to an analog-to-digital converter.

The optical signal transmission system includes one or more optical wave guide switches ( to ) for switching between transmission paths for transmission of light signals and an optical level adjusting device ( to ) connected with the one or more optical wave guide switches in at least one of the transmission paths. The optical level adjusting device ( to ) controls its own light transmittance with a thermooptic device ( ) and the one or more optical wave guide switches ( to ) switch between transmission paths by a similar thermooptic device ( ). The one or more optical wave guide switches and the optical level adjusting device are arranged in an integrated thermooptic circuit in a common substrate.

A device for acquiring operating parameters on electric motors with an arrangement that is influenced by an effect of at least one operating parameter of an electric motor. The arrangement is designed to store and display the effect. To obtain reliable information regarding the recyclability of the electric motor, the operating time and/or the number of motor starts can be detected by an electronic circuit and stored in a memory from which respective data can be read out and analyzed at a proper time.

An optical, beam-splitting component has a prism carrier plate which supports a prism member upon which a deflecting layer is applied. At the same time, the prism member juts into a groove between two optical waveguides carrying the light signals.

Optical, beam-splitting component and a method for producing a prism

In the case of the above devices, exact adjustment is very important; however, the devices ought to be very compact. It is not sufficient to utilize the silicon etching technique for the precision. The optical transmitting element (LD) is situated on a first carrier (T1), the optical receiving element (PD) and the transmission fiber (Fa) are situated on a third carrier. Provided in between them is a second carrier (T2) which is transparent to the wavelength of the light emitted by the transmitting element (LD). The carriers are structured by means of anisotropic etching in order to make possible the accommodation of the individual components. In addition, the carriers lie flat on one another and can thus be adjusted. A monitor diode (MD) is provided. Application of the arrangement in all transmission systems having optical waveguides.

Optical fiber transmitting and receiving communications device

A method for producing a hybrid integrated optical circuit which utilizes a molding tool having holding devices for an electrooptic semiconductor component and negative molds for a waveguide trench and holding devices for an optical waveguide. The holding devices of the molding tool adjust the electrooptic semiconductor component with respect to the negative mold of the waveguide trench during reshaping with a polymer. The basic unit produced consists of the electrooptic semiconductor component, which is adjusted with respect to the waveguide trench molded in the polymer. Adjoining the waveguide trench are holding devices, which are molded in the polymer and by means of which an optical waveguide can be coupled to the waveguide trench in a self-adjusting fashion. The basic unit and the optical waveguide are permanently connected to one another with the aid of a cover, the waveguide trench being filled with an optically transparent material, as a result of which a waveguide is formed.

An integrated-optical circuit receives optical signals and modulates and reflects incoming optical signals. The integrated-optical circuit includes a light guide with at least one Bragg resonator evanescently coupled to light guides and a photocell coupled to a Bragg resonator as well as a modulating device that modulates and reflects an additional optical signal that is received.
