DEFINITION

Classification: 505/846

Using superconductive quantum interference device (i.e., SQUID): (Class 324/248):

(under subclass 845) Subject matter wherein the direction or intensity of a magnetic field is sensed by a device, known as a SQUID, comprised of a superconducting loop containing one or two weak links, known as Josephson junctions, which permit conduction through a thin dielectric layer by quantum mechanical tunneling.
