  • Patent number: 10921126
    Abstract: Pulsating radio star (PULSAR) navigation systems and methods can include a plurality of PULSARs that can emit PULSAR radiation pulses in the millisecond range, and a plurality of Josephson Junctions (JJs) that can be arranged as an array of microantennas. The systems and methods can include a cryogenic cooling system for cooling the JJs to an operating temperature based on the JJ materials, and a thermal management system for maintaining the operating temperature. An oscillator can determine times of arrival (TOAs) of magnetic field components of the PULSAR pulses. A processor can compute the terrestrial position of the navigation system using the TOAs and the known celestial position of the PULSARs. A GPS sub-system can be included for navigation using GPS signals. The processor can be configured to compute terrestrial location using the PULSAR magnetic field components when GPS signal strength falls below a predetermined level or is lost.

  • Patent number: 10802086
    Abstract: A circuit includes a Superconducting Quantum Interference Array (SQIF), a bias circuit, and a coil. The SQIF generates an output voltage that is a transfer function of the magnetic flux perpendicularly passing through the SQIF. An external magnetic field and a bias magnetic field supply the magnetic flux. The bias circuit generates a bias current for biasing the SQIF at an operating point. The coil generates the bias magnetic field through the SQIF from the bias current of the bias circuit. The bias magnetic field provides nullifying feedback to the SQIF that counterbalances a low-frequency portion of the external magnetic field, such that the output voltage of the SQIF detects a high-frequency portion of the external magnetic field. The circuit can be a receiver with the output voltage of the SQIF detecting an electromagnetic signal while the receiver is moving with changing orientation relative to the Earth's magnetic field.

  • Patent number: 10338157
    Abstract: A biosignal measuring device that can include at least one Super-conducting Quantum Interference Device (SQUID) array (SQA) of High Temperature Superconducting (HTS) Josephson Junctions (JJs). The HTS JJs operating parameters can be adjusted to establish an anti-peak response for the SQA, that can be at a maximum along a defined response axis, for detection of extremely small biomagnetic fields. For operation, the SQA can be maneuvered around a target area of a stationary subject that is emitting biomagnetic signals using a stand with three degrees of freedom, so that the response axis remains orthogonal to the subject target area. The device can further include a radome with an atomic layer deposition (ALD) window on the radome surface. The radome ALD surface can allow for passage of magnetic signals through the ALD window and radome, while simultaneously preventing passage of infrared radiation therethrough.

  • Publication number: 20190051553
    Abstract: A method of fabricating a graphene device generally involving depositing a graphene monolayer from a carbon source on a metal catalyst layer; depositing a transfer substrate on the graphene monolayer by way of casting, thereby forming a transfer-substrate/graphene/metal-catalyst structure; annealing the transfer-substrate/graphene/metal-catalyst structure, thereby forming an annealed transfer-substrate/graphene/metal-catalyst structure; coupling a thermal adhesive with the transfer-substrate/graphene/metal-catalyst structure; moving the annealed transfer-substrate/graphene/metal-catalyst structure to a target area of a target device, by using a probe assembly or the like, thereby forming an annealed transfer-substrate/graphene/metal-catalyst/thermal-adhesive/target-device structure; releasing the slip of thermal adhesive from the annealed transfer-substrate/graphene/metal-catalyst thermal-adhesive/target-device structure by applying heat, thereby forming an annealed transfer-substrate/graphene/metal-catalyst/

  • Patent number: 8644898
    Abstract: A device includes a circuitry layer having one or more circuitry regions and a superconducting layer having a plurality of naturally-occurring defects. Potential wells are formed in the superconducting layer and located outside of the bounds of the circuitry regions. A pattern of engineered defects is formed in the superconducting layer and are configured such that, upon encountering a pulse of electromagnetic energy applied at a high potential region of the superconducting layer prior to energizing any circuits within the circuitry layer and when the superconducting layer is in a superconducting state, magnetic flux trapped within the naturally-occurring defects is directed to one or more of the potential wells.
