  • Patent number: 11300644
    Abstract: The technology disclosed in this invention belongs to both the field of Nuclear Quadrupole Resonance (NQR) and nuclear geomagnetic resonance application. Technically, a nuclear quadrupole resonance detection system and its antenna are provided. The antenna includes two coils to make a gradient antenna wherein they simultaneously receive both the signal from the target region and the external radio frequency interference. Structurally, the first coil is positioned as a regular circular coil, while the second coil is annular and evenly distributed around the first coil peripherally. These coils are on the same plane with equal areas but have opposite winding directions. The systems specific to the disclosed antenna are also included. The configuration of the invented antenna can effectively increase the capability of suppressing environmental electromagnetic radio frequency interference, thereby enhancing the detection of the NQR or geomagnetic resonance signals.

  • Patent number: 11255929
    Abstract: Aspects of the present disclosure generally pertain to a magnetic field sensor with flex coupling structures. Aspects of the present disclosure are more specifically directed toward Nanoscale Superconducting Quantum Interference Devices (nanoSQUIDs) with very low white flux noise characteristics can be fashioned into very sensitive magnetic field sensors by using external structures to increase the amount of flux that passes through the nanoSQUID aperture. One such structure is a superconducting coupling loop that shares part of a circuit with the nanoSQUID, and couples flux into the nanoSQUID primarily through kinetic inductance rather than geometric inductance.

  • Patent number: 11248968
    Abstract: Microwave radiometers (MRs) and methods for detecting microwave emissions using an electro-optical receiver that incorporates a photonic integrated circuit are provided. The electro-optical receiver includes an electro-optic modulator that modulates received radio frequency signals onto an optical carrier signal supplied by a pump laser. The resulting upconverted signal, containing the full spectrum of the radio frequency signals, is divided into channels by an optical filter. Each of the channels is connected to a corresponding photodetector, which produces an electrical output having an amplitude that is proportional to the amplitude of the received optical signal. The components included in the photonic integrated circuit can be formed on a single substrate. In addition, the optical filter can filter the received full spectrum optical signal into a large number of channels (e.g. greater than 50).

    Abstract: Magnetic field components are measured at multiple longitudinal positions and used to calculate estimated longitudinal position and length of a transversely localized electric current segment flowing across a gap between conductive bodies. The apparatus can be used with a remelting furnace. The electrode and ingot act as the conductive bodies, and arcs, discharges, or slag currents are the current segments spanning the gap. Actuators for movable sensors can be coupled to the sensors in a servomechanism arrangement to move the sensors along with the moving gap. An actuator for moving one of the conductive bodies can be coupled to sensors in a servomechanism arrangement to maintain the gap distance within a selected range as the gap moves.
