  • Non-contacting aligning method for planes in three-dimensional environment
    Patent number: 8355122
    Abstract: A non-contacting aligning method for planes in a three-dimensional environment is disclosed. The method includes: projecting a light beam in a predetermined incident angle onto a transparent first object and an opaque second object that are facing each other; and calculating a distance between the first and second objects basing on the tangent trigonometric function of the incident angle of the light beam.
    Type: Grant

  • MAGNETOMETER AND GRADIOMETER OF IN-SERIES SUPERCONDUCTING QUANTUM INTERFERENCE DEVICES (SQUIDs)
    Publication number: 20080001599
    Abstract: The invention is about cascading high-transition-temperature superconducting quantum interference devices (SQUIDs) for sensing magnetic fields. These SQUIDs in series are connected with coils for picking up detected magnetic signals. Depending on the patterns of pick-up coils, magnetometers or gradiometers, which sense the magnetic field intensity and magnetic field gradient respectively, are achieved. Examples of magnetometers and gradiometers includes cascading high-Tc SQUIDs in series are provided.
