  • Patent number: 5021798
    Abstract: A horn type microwave antenna includes a main reflector and sub-reflector that are supported in proper spaced relationship by flexidigit robotic manipulators, multisection arms that are capable of positional changes, whereby the supports may be changed in position responsive to the application of control voltages. At least a portion of the manipulators include piezo electric actuators, permitting rapid adjustment of the reflectors' position.

  • Patent number: 4964062
    Abstract: A multisection flexible multidigit arm contains hands at each end, each of which hands contains a set of fingers, suitably three, which are similarly formed flexible multidigit arms constructed to a smaller scale. Each hand contains connectors for coupling the hand to a mating connector mounted on an associated structure to provide appropriate power and control signals to the arm. One hand may grip the connector and the other hand is free to move to various positions and perform various tasks. In an additional aspect the arm may move to different locations by somersaulting between spaced connectors in the system. In an assembly system the robotic arms are used to construct frames or other assemblies.A completely self contained arm includes a self contained source of power. Radio communication means are provided to allow electronic interaction with the arm from a remote location.

  • Patent number: 4953961
    Abstract: A light deflection apparatus includes a pair of mirrors in confronting relationship, one of which is fixed in position and contains a central window, in which to input a laser light beam or in which to mount a suitable light beam generating source, such a diode laser. The other mirror is movably mounted so as to permit varying the degree of tilt between the mirrors and azimuthal location of the bisecting plane of symmetry and the spacing. The apparatus is adapted to permit targeting of light beams to different objects rapidly for use in communications systems and military systems. The apparatus also is adapted to function as the light positioning element of an optical spatial modulator.

  • Patent number: 4848179
    Abstract: A multidigit arm contains a plurality of sections, each of which is positionable angularly and spatially to a predetermined degree with respect to an adjacent section. Control means are provided for selectively individually positioning each section within said arm with respect to an adjacent section, such control means including actuator means positioned within and carried by and between the arm sections. The arm may be formed into a variety of curves and position the arm end at a variety of positions.
