    Abstract: A superconducting device operable at temperatures in excess of 30oK and a method for making the device are described. A representative device is an essentially coplanar SQUID device (10, 56A, 56B, 58A, 58B) formed in a single layer (12) of high-Tc superconducting material, the SQUID device (10, 56A, 56B, 58A, 58B) being operable at temperatures in excess of 60 K. High energy beams (34), for example ion beams, are used to convert selected portions (30) of the high-Tc superconductor layer (12) to nonsuperconducting properties so that the material now has both, superconducting regions (20A, 20B) and nonsuperconducting regions (30). In this manner a superconducting loop (16A, 16B, 20A, 20B) having superconducting weak links (16A, 16B) can be formed to comprise the SQUID device.

    Abstract: A method and system for tracking an object (3) within a volume, includes coupling a rotating magnetic dipole (2) to the object (3), measuring (4) the magnetic fields either remotely, on the surface of, or exterior to the volume, to produce measurements; and based on the measurements, determining the position and the orientation of the magnetic dipole (2), thereby to determine a position and orientation of the object (3).
