Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
94 words
An apparatus for detecting meteoroid penetration comprising: a large area detector panel means having a plurality of interconnected pressurized cells pressure formed therein, said panel means including at least a pair of opposed panels being sealed around their periphery and said cells being tufted in their centers at which point a junction is made between said opposed panels so as to give greater structural stability to the entire panel means while facilitating reduced internal volume; and means for detecting and permanently recording pressure drop in said cells due to meteoroid penetration of said panel.
Claim 2
Independent Claim
94 words
An apparatus for detecting meteoroid penetration comprising: a large area detector panel means having a plurality of interconnected pressurized cells pressure formed therein, said panel means including at least a pair of opposed panels being sealed around their periphery and said cells being tufted in their centers at which point a junction is made between said opposed panels so as to give greater structural stability to the entire panel means while facilitating reduced internal volume; and means for detecting and permanently recording pressure drop in said cells due to meteoroid penetration of said panel.
Claim 3
Dependent Claim
22 words
The apparatus as in claim 1 in which the cells are hexagonal in shape, said hexagonal configuration having more inherent structural rigidity.
Claim 4
Dependent Claim
26 words
The apparatus as in claim 1 wherein the cell perimeters are welded; and spaces in said perimeter welds to provide means for communication between the cells.
Claim 5
Dependent Claim
17 words
The apparatus as in claim 1 in which the cells can be formed in any desired configuration.
Claim 6
Dependent Claim
13 words
The apparatus as in claim 1 wherein said tufted junction is a spot-weld.
