Abstract
Abstract In combination: a frame; an outer gimbal mounted in the frame for pivotal movement about a first axis; an inner gimbal mounted in the outer gimbal for pivotal movement about a second axis orthogonal to the first axis; a sensor having a longitudinal axis; apparatus mounting said sensor in the inner gimbal with the longitudinal axis orthogonal to said second axis; apparatus carried by the frame for causing rotation of the outer gimbal about the first axis; and apparatus carried in part by said frame and in part by said inner gimbal for causing rotation of the inner gimbal about the second axis.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
171 words
In combination: a frame; an outer gimbal mounted in said frame for pivotal movement about a first axis; an inner gimbal mounted in said outer gimbal for pivotal movement about a second axis orthogonal to said first axis; a sensor having a longitudinal axis; means mounting said sensor in said inner gimbal with said longitudinal axis orthogonal to said second axis; means carried by said frame for causing rotation of said outer gimbal about said first axis; and means carried in part by said frame and in part by said inner gimbal for causing rotation of said inner gimbal about said second axis, the last named means comprising a pin carried by said inner gimbal and aligned with said longitudinal axis, and an arcuate member pivoted in said frame about a third axis orthogonal to said first axis, and having a slot lying in a plane containing said third axis and receiving said pin, said axes intersecting at a common point and said slot being arcuate generally about said common point.
Claim 2
Dependent Claim
171 words
In combination: a frame; an outer gimbal mounted in said frame for pivotal movement about a first axis; an inner gimbal mounted in said outer gimbal for pivotal movement about a second axis orthogonal to said first axis; a sensor having a longitudinal axis; means mounting said sensor in said inner gimbal with said longitudinal axis orthogonal to said second axis; means carried by said frame for causing rotation of said outer gimbal about said first axis; and means carried in part by said frame and in part by said inner gimbal for causing rotation of said inner gimbal about said second axis, the last named means comprising a pin carried by said inner gimbal and aligned with said longitudinal axis, and an arcuate member pivoted in said frame about a third axis orthogonal to said first axis, and having a slot lying in a plane containing said third axis and receiving said pin, said axes intersecting at a common point and said slot being arcuate generally about said common point.
Claim 3
Dependent Claim
43 words
The combination of claim 1 further including means giving a first signal representative of the rotated position of said outer gimbal about said first axis, and means giving a second signal representative of the rotation of said arcuate member about said third axis.
