  • Patent number: 8036009
    Abstract: Power is supplied to excitation windings in order to generate magnetic fields, preferably for activating superconducting coils. An AC transformer is used, and triggering of the coil is performed via a rectifier having little power loss. Preferably, a two-way rectifier using a freewheeling circuit is utilized in the associate device, thus preventing losses when power is supplied and especially when the power is discharged.

  • Patent number: 7564251
    Abstract: Individual measuring sensors each have a different specific signal type and must therefore be appropriately connected to the analog measuring inputs. An adjustable voltage with adjustable current limitation, or an adjustable current with adjustable voltage clamping is used. The voltage or current is connected to the measuring sensors and the corresponding signal is detected and classified according to the sensor type. This permits the automated integration of the measuring sensor. The corresponding assembly can form part of the complete module.

  • Patent number: 7242177
    Abstract: A method with corresponding circuit arrangement is disclosed, whereby for evaluation of a measured signal arising as an analogue value with a potential greater than zero potential in a measuring device requiring a supply current, the measured information therefrom is transmitted as a digital signal to an analytical unit lying at earth potential after an A/D conversion. The generated digital signal thus provides the clock signal for a modulation of the supply current and thus also carries out the function of the carrier for the information content of the measured signal. Curved characteristic lines for compression/decompression of the signals are used. Suitable devices for temperature compensation may be similarly provided.

  • Patent number: 7015702
    Abstract: In order to measure the current in a shunt, the voltage drop in the resistor of said shunt is evaluated as a measurement of the current. Normally, galvanic separation of the measuring device is required for high-potential shunts. A digital measuring signal provides the clock pulse for modulation of the supply current for the measuring device after an A/D conversion. The modulated supply current is also used as a carrier for the measuring information. In the associated evaluation device, an A/D converter and a modulation unit are arranged downstream from an amplifier for voltage signal which is picked off from the shunt. The modulated measuring signal is transmitted to an evaluation device.

  • Patent number: 4956566
    Abstract: From two path- or angle-dependent signals (A, B) of identical amplitude and period generated by an incremental generator (GS) which signals have a phase shift of 90.about. el. to each other a sequence signal .vertline.A.vertline./(.vertline.A.vertline.+.vertline.B.vertline.) dependent linearly on the path or angle is formed in that the generator signals (A, B) are rectified and a signal is formed in a converter (U1 ) corresponding to the quotient of the magnitude (.vertline.A.vertline.) of one of the two generator signals (A) to the sum of the magnitudes (.vertline.A.vertline.+.vertline.B.vertline.) of both generator signals (A, B). From the sequence signal the position within a particular quarter period is determined. Which quarter period this is in each instance is determined by an investigation of the position of the generator signals (A, B) with respect to each other.
