  • Patent number: 9664742
    Abstract: A method and a device for measuring a current flowing through a switch which has an unknown inner resistance and two connections, a voltage difference being measured at the switch. During operation, the current provided by an AC voltage source, which is part of an AC voltage circuit connected in parallel with the switch, is superimposed on the current to be measured, the current flowing through the switch, by way of the AC voltage source. Both the amplitude and the frequency of the current provided by the AC voltage source are known. An AC voltage component of the voltage difference and the amplitude of the component are ascertained, and the current between the connections is ascertained and output proportionally to the amplitude of the current of the AC voltage source.

  • Publication number: 20130293987
    Abstract: A quench detection device (or method) is provided that receives real-time information of concurrently monitored electrical characteristics of a high temperature superconducting (HTS) device, or any superconducting material, device, or system including low temperature superconductors, during operation. The quench detection device determines whether an electrical threshold is satisfied based on the received real-time information. The quench detection device detects a quench condition if the electrical threshold remains satisfied over a predetermined period of time or a predetermined successive number of times. If a quench detection is detected, the quench detection device sends a signal to terminate the operation of the HTS device.

  • Patent number: 6605949
    Abstract: In a quasi-hemispherical Fabry-Perot resonator for the non-destructive determination of the surface resistance Rs of electrically conductive thin material films, spherical and planar mirrors are disposed opposite each other in a double shielded cooled resonator space structure supported on individual base plates and the planar mirror, on which a wafer with the thin material film is supported, is mounted on a support arm which extends through the double shield structure. Shield sections through which the support arm extends are supported on pivot arms which are pivotally mounted in the center of the base plates and the shield sections are engaged by the support arm so that they move along with the support arm when the support arm is moved sidewardly for a positioning change of the planar mirror thereby preventing radiation leakage from the resonator space.
