Abstract: An arrangement of hot-wire anemometers is set partially into the rotor boary layer so that they form two resistors of a wheatstone bridge circuit for each axis. The hot wire resistors change in resistance according to the angular offset from null of the gyro rotor. The combination of resistance changes is then used in the bridge circuit to provide an electrical signal which is directly proportional to gyro rotor angular offset.

Abstract: An inclinometer which employs a laser light source with a transparent liq and a gas and the laws of optics to reflect the light source to a detector which provides signals for measuring the tilt angle and the direction of tilt from the local horizontal.

Abstract: A reaction-jet torquer system carried in a projectile to aim the projectile o a target. The torquer system uses the thrust of sonic nozzles to control a gyro rotor inertial frame of reference. The reaction force applied to the gimbal gives the rotor the capability of tracking the target. A sensor carried by the gyro provides logic which identifies and activates the appropriate nozzle or nozzles of the system to generate the required gimbal force.

Abstract: A fluidic accelerometer employing a transverse-impact modulator for measug acceleration or velocity of a body along a specified axis of the accelerometer. This device uses two similar collinear power-input tubes directed toward each other. The axially opposing power jets from the tubes impact where the flow meets an air-bearing supported proofmass containing annular rings and produce symmetrical radial flow cones at the balance point. A change in the position of the proofmass causes the balance point to move which causes the radial flow cones to become asymmetrical and a net pressure difference is developed in the output receivers.

Abstract: A fluidic accelerometer employing a direct-impact modulator for measuring celeration or velocity of a body along a specified axis of the accelerometer. This device uses two similar collinear power-input tubes directed toward each other. The axially opposing power jets from the tubes impact where the flow meets an air-bearing supported proofmass containing annular rings and produce symmetrical radial flow cones at the balance point. A change in the position of the proofmass causes the balance point to move which causes the radial flow cones to become asymmetrical and a net pressure difference is developed in the output receivers.

Abstract: A transportation machine such as a ballistic missile disposed for operation n a linear path is provided with a chassis including an aerate atmosphere and a gyroscopic rotor for development therearound of a pressurized aerate ring and for axial orientation in the linear path. A stabilizer develops signals responsive to differences in pressures between the aerate atmosphere and the pressurized ring for rotation of the chassis to axial coincidence with the rotor responsive to the signals.
