摘要： Contactless determination of electrical parameters. The examples describe a method and apparatus for determining electrical parameters of assemblies (printed circuit boards and as well as passive components) by the contactless determination of the spatial distribution of material. The spatial distribution of material (two-dimensional or three dimensional), is determined for example by measurement by radiographic technology with an X-ray machine or a computer tomography or by an optical instrument. The electrical parameter is determined in each volume element whose size is determined by the resolution of the method used for determining the material distribution, or a partial structure of the conductive structure.

摘要： A low-temperature superconducting device for measuring gravity, includes a low-temperature container, a cryocooler, a rotor chamber, a superconducting rotor, an upper levitation coil, a lower levitation coil, an upper electrode, an intermediate electrode, a lower electrode, a magnetic shielding chamber and a superconducting quantum interference device. By cooling the whole low-temperature superconducting device using a cryocooler, the intermediate electrode disposed in the body of the magnetic shielding chamber will generate an output voltage when the superconducting rotor is displaced due to a change of gravity. Thus, the superconducting quantum interference device can make the superconducting rotor return to the central balance position by adjusting the operating current of the upper levitation coil or the lower levitation coil. A change of gravity can be determined based on the operating current fed back to the upper levitation coil or the lower levitation coil.

摘要： 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.

摘要： A head with a pick-up coil is attached to a supporter so that the head is freely movable along the direction perpendicular to the surface of a superconductor. Fluid spouted from the spout hole of the head maintains the height (gap space) of the head from the surface. The head is firmly fixed to the supporter in the direction along the surface. Since the relative position of the head in the direction along the surface of the superconductor is changable by drive means for moving the superconductor or the head, the distribution of the magnetic flux which is trapped in the superconductor is measured by scanning the surface of the superconductor with pick-up coil.
