In a system which includes a driven shaft that has limited angular rotation capabilities from a start position clockwise and counterclockwise through a common overlapping angular region, a device for enabling the determination of which desired direction the shaft should be rotated from the region in order to return to the start position including a first member connected for motion with the shaft rotation and a second member mounted for independent motion when moved by the first member in a first direction, the second member being held in the start position with motion of the first member in a second direction, and a sensor to sense the presence of the second member in the start position as an indication of the desired direction.

A magnetic isolation and pointing gimbal apparatus provides support functions and multidegree of freedom pointing capability and simultaneous six degree of freedom bi-directional disturbance isolation. This is accomplished by integrating the support, isolation and pointing functions within one contiguous gimbal assembly. The apparatus comprises a housing having a shaft rotatably mounted therein such that the centroidal axis of the shaft is coaxial with that of the housing. A linear, two-axis, large gap, radial magnetic actuator is mounted in the housing concentrically with the shaft. A radial armature is mounted on the shaft adjacent the radial magnetic actuator. A set of linear, large gap, axial magnetic actuators are mounted in the housing. An axial armature is connected to the shaft and extends between the axial magnetic actuators. A torque motor is also connected to the shaft. A large gap, rotational position sensor has a first portion connected to the shaft and a second portion connected to the housing.
