Dual suspension gyroscopic device having powered gimbal support

A device as claimed in claim 6 wherein said data transferring means includes:

• a first printed circuit board secured to said first upper pivot part and rotatable therewith;
• a second printed circuit board secured to said second upper pivot part and rotatable therewith, said first and second printed circuit boards being in facing relationship;
• said slip rings being conductively connected to points on said first printed circuit board;
• said synchro element including a winding conductively connected to points on said second printed circuit board;
• and
• flexible conductor means interconnecting points on said first and second printed circuit boards.

A gyroscopic device, comprising:

• a gyroscope having at least a single degree of freedom and including a first case, a float, a wheel defining a spin axis within said float and low torque means for supporting said float in said first case for relative motion between said float and said first case about a leveling axis;
• a gimbal;
• means pivotally mounting said first case to said gimbal for relative motion between said gimbal and said float about said leveling axis;
• means responsive to relative motion between said first case and said float for caging said first case to said float;
• a second case;
• upper and lower pivot means supporting said gimbal in said second case for relative motion between said gimbal and second case about a second axis perpendicular to said leveling axis;
• a first torque motor for applying torque to one of said pivots to rotate said gimbal relative to said second case;
• means for sensing relative motion between said first case and said gimbal about said leveling axis and for controlling said first torque motor in accordance with said motion sensed about said leveling axis, the torque applied by said first torque motor to said gimbal tending to maintain the gyroscope spin axis in a referenced plane;
• a synchro having a stator and a rotor for transmitting data indicative of the displacement of said gimbal relative to said second case, said synchro stator being fixed to one of said gimbal pivots, said synchro rotor being fixed to said second case;
• data transmitting means including slip rings connected to windings of said synchro rotor for transmitting data signals from said synchro to points of utilization external to said second case;
• means rotatively coupling said data transmitting means to one of said gimbal pivots;
• a second torque motor for rotating said data transmitting means relative to said second case;
• and
• means for sensing relative motion between said synchro rotor and said data transmitting means for controlling said second torque motor to maintain the displacement between said data transmitting means and said synchro rotor at a minimum.
