Apparatus for detecting changes in shape of a body
First Claim
1. A detector capsule for being attached to a wall of a body, said capsule comprising at least one flexible diaphragm, one said flexible diaphragm engaging and moving complementarily with both concave and convex distensions of said wall, means for pneumatically connecting said capsule to a transducer responsive to variations in volume in said capsule as a result of changes in said wall, and means including resiliently deformable material located within said capsule for constantly urging said one diaphragm into virtually complete engagement with said wall.

Abstract
An apparatus for detecting and measuring changes in the shape of a wall of a body includes a detector capsule adapted for attachment to the wall and pneumatically connected to a volume transducer responsive to changes in the internal volume of the apparatus produced by changes in the shape of the wall. The internal volume of the capsule is partially defined by a flexible diaphragm for engagement and complementary movement with the wall. The capsule contains a resiliently deformable material which presses the diaphragm into contact with the wall regardless of the convex or concave shape of the wall.
