Abstract
Abstract A receiving system including a mirror mounted on a pair of gimbals to direct light to a stationary detector, wherein the inner gimbal is driven from a drive shaft which rotates at twice the speed as the mirror and in the same direction. Gyroscopes and position transducers are mounted on the drive shaft.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
A space stabilized system comprising: a head; an outer gimbal rotatably mounted on said head; mirror means rotatably mounted on said outer gimbal and having a first axis; a drive shaft rotatably mounted on said outer gimbal and having a second axis parallel to said first axis; motor means mounted on said drive shaft to rotate around said second axis; gyro means mounted on said drive shaft to respond to rate of movement around said second axis; position transducer means mounted on said drive shaft to respond to angular position around said second axis; means coupling said gyro means and said position transducer means to said motor means; and drive means having a first and a second rotating structure respectively mounted on said drive shaft and said mirror means, said drive means providing a two to one angular rotation ratio between said first and second rotating structures, said drive means rotating said mirror means and said drive shaft in the Same direction.
Claim 2
Dependent Claim
162 words
A space stabilized system comprising: a head; an outer gimbal rotatably mounted on said head; mirror means rotatably mounted on said outer gimbal and having a first axis; a drive shaft rotatably mounted on said outer gimbal and having a second axis parallel to said first axis; motor means mounted on said drive shaft to rotate around said second axis; gyro means mounted on said drive shaft to respond to rate of movement around said second axis; position transducer means mounted on said drive shaft to respond to angular position around said second axis; means coupling said gyro means and said position transducer means to said motor means; and drive means having a first and a second rotating structure respectively mounted on said drive shaft and said mirror means, said drive means providing a two to one angular rotation ratio between said first and second rotating structures, said drive means rotating said mirror means and said drive shaft in the Same direction.
Claim 3
Dependent Claim
46 words
The system described in claim 1 including: an outer torquer motor for rotating said outer gimbal, including a ring shaped permanent magnet field assembly fixed to said outer gimbal and a ring-shaped armature assembly fixed to said head at a position adjacent to said field assembly.
Claim 4
Dependent Claim
54 words
The system described in claim 1 wherein: said drive means comprises a first pulley mounted on said mirror means, a second pulley of one-half the diameter of said first pulley mounted on said drive shaft and band means extending between said first and second pulleys to couple them for rotation in the same direction.
