  • Publication number: 20200200538
    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: 10512425
    Abstract: An apparatus, method and system for dermatologically noninvasive testing for blood sugar concentration using an interferometry optical design. The present apparatus, method and system are used to measure the optical properties of blood, without puncturing the skin or drawing blood samples. They incorporate the use of an electromagnetic light source and two optical polarizers. A dermatological sample, e.g., the earlobe, webbing between fingers, is illuminated with polarized electromagnetic light. When the linearly polarized light passes through this dermatological sample, the blood in the dermatological sample acts as an optical rotator due to the optical interaction with the blood sample. The presence of molecular chirality in the blood sample induces optical activity. After the skin is illuminated, a second polarizer finds the orientation of the polarization by maximizing the intensity on the photo detector. As a result, the blood sugar concentration may be determined.

  • Patent number: 10381506
    Abstract: An optoelectronic device is provided that includes a doped substrate, a tunneling barrier, a direct bandgap two dimensional semiconductor material, a hot electron emitter, a gate electrode, and a voltage bias. The hot electron emitter injects hot electrons from the underlying substrate into the conduction band of the direct bandgap two dimensional semiconductor material via quantum tunneling. The gate electrode is operable to provide the voltage bias in a direction normal to the X-Y plane of the direct bandgap two dimensional semiconductor material so as to generate an electric field perpendicular to the direct bandgap two dimensional semiconductor material. The voltage bias provided by the gate is operable to change an optical bandgap of the direct bandgap two dimensional semiconductor material continuously from the visible to the mid-infrared spectral regime via an electric dipole layer enhanced Giant Stark Effect for electrically-tunable hot electron luminescence applications.
