Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
87 words
A system for the identification of an object comprising: a material matrix; a plurality of inclusions located within said material matrix in a random configuration, at least one of the inclusions being constituted by a piezo electric crystal transducer; and means for providing electrical connection between the or each transducer and external ultrasonic testing apparatus when the system is, in use, associated with an object to be identified, thereby to produce an output which is unique to the particular configuration of said inclusions within the material matrix.
Claim 2
Independent Claim
87 words
A system for the identification of an object comprising: a material matrix; a plurality of inclusions located within said material matrix in a random configuration, at least one of the inclusions being constituted by a piezo electric crystal transducer; and means for providing electrical connection between the or each transducer and external ultrasonic testing apparatus when the system is, in use, associated with an object to be identified, thereby to produce an output which is unique to the particular configuration of said inclusions within the material matrix.
Claim 3
Dependent Claim
44 words
A system as claimed in claim 1, in which said material matrix is contained in a hollow body,and said means for providing electrical connection includes an electrically conductive member extending between the or each transducer and an electrically conductive exterior portion of said body.
Claim 4
Dependent Claim
54 words
A system as claimed in claim 2, in which said body comprises a first body member having a recess therein which contains said material matrix, and a second body member constituting a cover which closes off the mouth of the recess, said electrically conductive exterior portion of the body being located in said cover.
Claim 5
Dependent Claim
75 words
A system as claimed in claim 3, in which two of said inclusions are each constituted by a piezo electric crystal transducer, one of said transducers being connected by respective electrical leads to the wall of the recess and to the electrically conductive exterior portion of the cover, and the other transducer being mounted directly on the recess wall and connected by a further electrical lead to said electrically conductive exterior portion of the cover.
Claim 6
Dependent Claim
42 words
A system as claimed in claim 3 or claim 4, in which said cover comprises a central electrically conductive part constituting said electrically conductive exterior portion, and an annular member of electrically insulating material which surrounds the periphery of said central part.
Claim 7
Independent Claim
67 words
A system as claimed in any of claims 1 to 5, which is adapted to constitute an identity seal for incorporate within or attachment to an object thereby to provide an indication of the identity of the object and also an indication of the integrity of at least a part of said object when the or each transducer is, in use, connected to exterior ultrasonic testing apparatus.
Claim 8
Dependent Claim
31 words
A system as claimed in claim 6, including the features claimed in claim 2, in which the body includes a cap adapted for attachment to a container for containing fissile material.
Claim 9
Dependent Claim
37 words
A system as claimed in claim 7, in which the cap includes a projection adapted for engagement with said container when the cap is attached thereto so as to be breakable upon subsequent removal of the cap.
