  • Patent number: 10811143
    Abstract: The invention is for a startup system for nuclear fusion engines in space. The combustion of hydrogen and oxygen produces heat that is used by a heat engine to produce electricity. This can be supplemented by electricity from other operating engines. The exhaust from the combustion is condensed and electrolyzed to produce hydrogen and oxygen once the engine is in operation. This provides a constant source of energy for future startups. The engine is started up at partial power in electricity generation mode and this power replaces the power from the combustion as it grows. The combustor uses the same heat engine as the nuclear engine uses for power generation.

  • Patent number: 10752385
    Abstract: A dipole cancellation system and method may include a plurality of magnetometers for measuring a device magnetic field associated with a plurality of device coils generating a device magnetic field having a primary magnetic dipole moment. A compensating coil carrying a compensating current running a first direction that generates a compensating magnetic field having a compensating magnetic dipole moment. The compensating coil may be positioned and the first current may be selected so that the compensating magnetic dipole moment completely cancels the primary magnetic dipole moment. A method may use the system to stabilize a spacecraft by calculating an estimated torque of the spacecraft, receiving a value for an external magnetic field, receiving a value for a device magnetic field, and calculating and applying a compensating current may be then applied to the compensating coil to cancel the primary magnetic dipole moment, wherein the spacecraft is stabilized.

  • Patent number: 9822769
    Abstract: A system and method for producing and controlling high thrust and desirable specific impulse from a continuous fusion reaction is disclosed. The resultant relatively small rocket engine will have lower cost to develop, test, and operate that the prior art, allowing spacecraft missions throughout the planetary system and beyond. The rocket engine method and system includes a reactor chamber and a heating system for heating a stable plasma to produce fusion reactions in the stable plasma. Magnets produce a magnetic field that confines the stable plasma. A fuel injection system and a propellant injection system are included. The propellant injection system injects cold propellant into a gas box at one end of the reactor chamber, where the propellant is ionized into a plasma. The propellant and fusion products are directed out of the reactor chamber through a magnetic nozzle and are detached from the magnetic field lines producing thrust.

  • Publication number: 20120313568
    Abstract: This invention is a solar-powered charging station for electric and hybrid vehicles. A vehicle parks at a space with the charging station and uses a credit card, debit card, cash, smart card or network connection to a database like EZ-Pass to pay for the space and the electricity. The station automatically charges the vehicle as long as it is connected to the station. The station automatically stops charging when the vehicle is fully charged. The customer only pays for the space and the electricity consumed. If the charging circuit is broken the customer must reinsert the smart card or credit card to restart charging. Sufficient funds are removed from the payment method on initiation of charging. Any money not used for charging is put back onto the smart card or account if the user reinserts it prior to leaving.

  • Publication number: 20120249775
    Abstract: The invention is for a sensor for use in spacecraft navigation and communication. The system has two articulated telescopes providing navigation information and orientation information as well providing communications capability. Each telescope contains a laser and compatible sensor for optical communications and ranging, and an imaging chip for imaging the star field and planets. The three optical functions share a common optical path. A frequency selective prism or mirror directs incoming laser light to the communications and ranging sensor. The Doppler shift or time-of-flight of laser light reflected from the target can be measured. The sensor can use the range and range rate measured from the incoming laser along with measurements from the imaging chip to determine the location and velocity of the spacecraft. The laser and laser receiver provide communications capability.

  • Patent number: 8193657
    Abstract: A vertical axis wind turbine that can be actively controlled is provided. This invention includes mechanisms and methods for enabling high-efficiency wind energy extraction by a vertical axis wind turbine using active pitch and camber control of individual blades. Blade control is further integrated with generator control and power electronics. Integrated control algorithms are systematically constructed, and transmitted to the wind turbine through a wireless communications interface. The interface also allows the user to continuously monitor the state of the wind turbine system. This invention includes sensors and procedures for periodic self-calibration of wind turbine parameters for preserving the long-term efficiency of wind energy extraction. Furthermore, a capability to intelligently interact with other wind turbine systems in a wind-farm setting is incorporated.

  • Patent number: 8081302
    Abstract: A Multimode Optical Sensor (MMOS) is a laser radar (ladar) that employs both coherent, or heterodyne, and noncoherent detection at long range, i.e. ranges for which the target is no more than a pixel in dimension. Coherent detection provides much higher velocity resolution while the noncoherent detection can provide better detectability.
