Patents by Inventor Ronald R. Sinclair

Ronald R. Sinclair has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Guidance system for a projectile
    Patent number: 4568039
    Abstract: Guidance is provided for a spinning projectile by measuring the magnitude of the angle between the spinning projectile and a target. This information is processed in conjunction with a body rate sensor to deduce the angular rate of the line of sight between projectile and the target. A means is provided for reducing the line of sight angular rate to zero, thus ensuring that the projectile will intercept the target.
    Type: Grant
    Filed: August 10, 1973
    Date of Patent: February 4, 1986
    Assignee: Sanders Associates, Inc.
    Inventors: John A. Smith, Ronald R. Sinclair
  • Infrared target seeker for spinning projectile
    Patent number: 4561611
    Abstract: An infrared target seeker for a spinning projectile which does not require any reticle motor or gimbals is provided by a solid unit including lenses, detectors and a reticle, which is etched on one of the lenses.
    Type: Grant
    Filed: August 10, 1973
    Date of Patent: December 31, 1985
    Assignee: Sanders Associates, Inc.
    Inventors: Ronald R. Sinclair, Theodore J. Nussdorfer
  • Canard control assembly for a projectile
    Patent number: 4512537
    Abstract: Control is provided to conventional gun-fired projectiles by substituting for the standard fuze thereof a device comprising a canard frame and a main housing, which threads into the fuze well of the projectile, with the canard frame being rotatable with respect to the main housing and having deflectable canards thereon for providing vernier correction on the trajectory to the projectile.

  • Prime power source and control for a guided projectile
    Patent number: 4438893
    Abstract: In a projectile including a spinning main housing and a despun canard frame having deflectable canards thereon, a pair of stator windings are disposed within the main housing and a cooperating pair of rotors are arranged within the canard frame. The first stator windings and corresponding rotor generate prime power and permit control of the rotational position of the canard frame while the second stator windings and associated rotor allow control of the deflectable canards.
