Abstract: An apparatus and method for controlling the movement of an elevator mechanism in a tape drive system. The mechanism of the present invention employs a tachometer to detect the magnetic decoupling of a cartridge from a cartridge reel motor. A holding torque is placed on the cartridge reel motor. A voltage or current ramp is supplied to the elevator mechanism, wherein the elevator mechanism raises and magnetically decouples the tape cartridge from the cartridge reel motor. As the coupling force is broken, the torque placed on the cartridge reel motor causes the motor to turn. The tachometer detects the magnetic decoupling of the cartridge from the cartridge reel motor by sensing the angular displacement of the motor. In response, the controller decreases the voltage or current ramp to adapt to the load reduction on the elevator mechanism, and thereby more smoothly continue the elevator motion.

Abstract: A 2-D correction system uses intermittent deployment of aerodynamic surfaces to control a spin or fin stabilized projectile in flight; correcting both crossrange and downrange impact errors. Intermittent surface deployment develops rotational moments, which create body lift that nudge the projectile in two-dimensions to correct the projectile in its ballistic trajectory. In low spin rate projectiles (“fin stabilized”), the rotational moment directly produces the body lift that moves the projectile. In high spin rate projectiles (“spin stabilized”), the rotational moment creates a much larger orthogonal precession that in turn produces the body lift that moves the projectile. The aerodynamic surfaces are suitably deployed over multiple partial roll cycles at precise on (deployed) and off (stowed) positions in the cycle to nudge the projectile up or down range or left or right cross range until the desired ballistic trajectory is restored.

Abstract: A solenoid valve moves an armature back and forth between valve open and valve closed positions without the armature having any sliding engagement with any fixed valve part. This is accomplished by supporting the armature with a spring having one periphery engaging a fixed valve surface and another periphery engaging the armature so that armature movement causes flexure of the spring, but no sliding contact. This helps prevent generation of dirt within the valve and ensures accurate armature movement to make the valve durable and reliable. Springs in both washer and cylindrical helical shapes can accomplish this.
