摘要:
Apparatus including an extruder, a die (110) having movable elements (112) defining the die opening, and die element drive solenoids for varying the dimensions of the die opening during extrusion function to yield an elongated body having a varying axial cross-section. Individual die member drive means (122) and a controller (138) are used with the apparatus to produce smoothly varying, complex cross-sectional shapes in elongated bodies such as optical fibers for various applications.

Apparatus for optical fiber data link between tow moving bodies remote controlled vehicle/missile such as ("RCV") (12) and hereinafter launch platform (17) includes fiber-wound bobbins having opposite winding directions on each body, interconnected with unwound, reinforced fiber sections, for streaming deployment from each bobbin through tensioning devices during relative separation movement between the two bodies. Image sensors and flight control mechanisms are operatively connected through an electric/optical I/O device to the fiber on the bobbin in the RCV (12), and data analysis/display devices and controller/command units are similarly interfaced with the fiber on the bobbin associated with the helicopter (17). The bobbin housing on the helicopter uses a shaped cavity and gimbal mount to provide free-streaming fiber deployment and pyrotechin or electro-mechanical separation device to discharge the bobbin and attached fiber after mission completion.
摘要:
A method and apparatus for covertly viewing a target using transmission of infrared radiation through an atmosphere having given atmospheric conditions. The target is illuminated with only a selected frequency band of infrared radiation having the least effective transmittance properties of all frequencies of infrared radiation in the given atmospheric conditions. This selected frequency band of infrared radiation is reflected from the target and detected. The selected frequency band of infrared radiation may be generated by generating a broad spectrum of infrared radiation and filtering this broad spectrum to output only the selected frequency band of infrared radiation. Alternatively, a laser may be employed to output the selected frequency band of infrared radiation.

摘要:
A method comprising alternately winding in one direction around the bobbin (34) compact (30) and crossover (52) layers. Each compact layer extends axially of the bobbin from a start end (36) proximate one end (38) of the bobbin to a finish end (40) proximate the other end (42) of the bobbin and includes a plurality of fiber turns (44) in virtual axial contact with each other which define generally parallel grooves (46) in the surface of the compact layer. The turn defining the start and finish ends of each compact layer is aligned with a respective start and finish set-back groove in the surface of the immediately preceding compact layer axially spaced from the respective start and finish ends of the preceding compact layer. Each crossover layer extends axially of the bobbin from the finish end of the preceding compact layer to proximate the start end of the preceding compact layer and includes one or more turns of fiber axially spaced from each other and disposed at an angle to the turns and grooves of the preceding compact layer.
摘要:
A multispectral band imaging and detecting device for use with a catoptric (10,18) zoom optical device having a focal plane (21). A plurality of electromagnetic radiation detectors are provided that are sensitive to one or more portions of the electromagnetic spectrum. An optical bench has the plurality of electromagnetic radiation detectors disposed thereon. A torque motor or the like is operatively connected to move the optical bench relative to the focal plane to move a selected one of the detectors into coincidence with the focal plane.

Apparatus for interconnecting a missile/RCV launch device with a remote control station includes composite cable having glass fibers for transmitting optical signals and electrical conductors embedded in a coating layer that is reinforced with fibers, for transmitting electric power. The apparatus also includes electrical and optical connectors at the cable end portions wherein the reinforcing fibers are grouped with the glass fiber at termination.
摘要:
A variable inertia energy storage system for storing large amounts of mechanical energy for an extended period of time on land or on a mobile vehicle includes a fly wheel having a rotating hub with spoke appendages each having an associate mass the center of which can be controllably changed with respect to the hub axis of rotation. The energy storage system also includes motor/generator elements for providing rotation forces to input mechanical energy to the flywheel or for generating electrical power for use on demand by a subsystem or the like.
