Articulated arm with shoulder joint |
April 20, 1993 |
| An articulated arm comprising at least one compact Coude optics system simulating a shoulder joint. In this Coude optics system, two mirrors rotate on one gimbal axis and the other two mirror pivot on the other gimbal axis. The axis of the two gimbals intersect and light beams passing |

Microwave camera |
June 9, 1992 |
| A camera system in which microwave radiation from objects in a field-of-view is collected by an antenna having a beam direction which is a function of the beam frequency. The collected radiation is analyzed to produce an image of the objects in the field-of-view. In a simple embodime |

Compact coude optics system |
May 19, 1992 |
| A compact coude optics system comprising a two axis gimbal system. Two mirrors rotate on one gimbal axis and the other two mirrors pivot on the other gimbal axis. The axes of the two gimbals intersect and light beams passing through the system effectively are turned at this point of |

Wide field multi-mode telescope |
April 21, 1992 |
| A telescope with a spherical primary mirror and movable lightweight secondary assembly which includes an optical, imaging component and at least one location component both of which components are attached to a pivot arm. The location component can be a microwave, radio frequency or |

Scanner beam semiconductor switching apparatus |
September 24, 1991 |
| A beam of radiation radiates in sequence an array of semi-conductor switches at an extremely rapid rate. Electron-hole pairs created by radiation permit the semiconductor switches to conduct electric current for a very brief period of time. |

Laser radar device |
July 9, 1991 |
| A laser radar system capable of measuring windspeed to within 1 m/s at distances in the range of 10 km. The system comprises two fast atomic line filter-detectors, a first filter-detector and a second filter-detector, in which a metal vapor is excited by signal light and further excited |

High power fast switch |
February 12, 1991 |
| A high power fast switch for generating pulses of current to a load from a high voltage power source. A laser beam illuminates a cathode which simulates the emission of pulses of electrons which illuminate a diamond target. The pulses of electrons cause the diamond target to become c |

Fast atomic line filter |
January 8, 1991 |
| A fast atomic line filter capable of operating at speeds and quantum efficiencies greatly in excess of prior art atomic line filters. Signal light excites to an intermediate energy level the atoms of a contained vapor. A pump beam further excited these atoms to a higher Rydberg level. |

Active segmented mirror including a plurality of piezoelectric drivers |
July 31, 1990 |
| A low cost segmented mirror for making wavefront corrections. The segmented mirror is comprised of a large number of closely spaced mirror element assemblies. Each assembly is comprised of an essentially flat mirror surface backed by a substrate and a tubular shaped piezoelectric driver |
