Patent Number Title Of Patent Date Issued
7438261 Stratospheric balloon utilizing electrostatic inflation of walls October 21, 2008
The high-altitude balloon has a skin made of nearly evacuated electrostatically inflated cells which provide thermal insulation to minimize heat loss from the gas in the balloon, while transmitting heat from the sun to heat the gas. The lower surface of the balloon is reflective to m
6988854 Cable dispenser and method January 24, 2006
Fiber-optic cable is dispensed underwater into a trench from a vehicle moving along the bed of the body of water. The cable is wound on a stationary spool and dispensed over the end of the spool by a rotary arm driven by a motor controlled to maintain a desired tension in the cable.
6963678 Electro-optical transducer with multi-reflector beam-expanding and collimating input/output devi November 8, 2005
A system of reflectors is used to form beam-expanding and collimating electro-optic transducer devices, including radiation sources and/or detectors. Preferably, the reflector system is of the Cassegrainian or Ritchey-Chretien type. Radiation such as light signals can be conducted to
6865333 Visual alignment of multiple-reflector collimation system March 8, 2005
A multiple-reflector collimator and beam spreader is aligned with a source point by visual means, in addition to or instead of an electrical detector, in order to avoid the need to send a signal through the system to a detector in order to align the components.
6739232 Towed airborne vehicle control and explosion damage assessment May 25, 2004
Device and method for controlling a towed vehicle such as a bomb damage detector towed on a tether cord behind the bomb. The towed vehicle is ejected from the bomb at a selected release point in its trajectory. A tether cord is wound on a spool and dispensed from the spool longitudin
6625376 Fiber-optic cable terminal connector and alignment device and method September 23, 2003
A system of reflectors is used to form a beam-expanding and collimating terminus and coupler for fiber-optic cables. Preferably, the reflector system is of the Cassegrainian or Ritchey-Chretien type. Alignment of optical conductors or "cores" of fiber-optic cables is provided by coup
6600855 Reflection suppression in multiple-reflector collimation system July 29, 2003
Reflections from an air-to-solid interface in a multiple reflector optical device are suppressed by giving the output surface of the device a slightly curved refractive surface so as to deflect the reflections away from the optical axis of the device. The device is shown in use as a
5678785 Fiber-optic cable dispenser and remotely controlled vehicle using same October 21, 1997
Fiber-optic cable is wound on a cylindrical bobbin without adhesive and is situated in the vehicle so that the cable, attached to a relatively stationary control computer station, is pulled freely off of the bobbin as the vehicle, such as a missile or torpedo, travels rapidly away from t
