  • Method and apparatus for passively slowing the spin rate of orbital objects
    Patent number: 9663250
    Abstract: Methods and systems for passively slowing the spin rate of an uncontrolled object in space are presented. A damper mechanism is provided that includes a magnet that is free to rotate in any direction about a central point with respect to a carrier or outer housing. The magnet can be carried within an inner element or sphere, that is in turn mounted within an outer sphere. The inner and outer spheres can be separated by a viscous fluid or other mechanism in which damping can be introduced. The damper mechanism can be associated with an attachment mechanism, that secures the resulting damper or despin system to a target object. A method of neutralizing the magnetic field is also included to enable the system to be launched in a passive state.

  • Cryoelectronic receiver front end for mobile radio systems
    Patent number: 6571110
    Abstract: The present invention relates to a novel use of cryoelectronic equipment to implement an extremely sensitive and stable receiver front end for UHF, microwave, and millimeter wave applications. The invention is particularly applicable to base station receivers in mobile radio systems, where the range and capacity of the systems are typically limited by the base station receiver sensitivity.
