Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
A flexible probe assembly comprising a plurality of tubular transducer sections, an elongated flexible support member extending through said tubular transducer sections, said elongated flexible support member being a flat strip element which supports bending in two directions, the tubular passage through said tubular sections including grooves to accommodate said flat strip element such that said flat strip element divides the tubular passage formed by said adjacent tubular transducer sections into two internal passages extending the length of said probe assembly, and means for maintaining adjacent tubular transducer sections in mechanical contact, said means in combination with said elongated flexible support member permitting mechanical flexing of said probe assembly.
Claim 2
Dependent Claim
109 words
A flexible probe assembly comprising a plurality of tubular transducer sections, an elongated flexible support member extending through said tubular transducer sections, said elongated flexible support member being a flat strip element which supports bending in two directions, the tubular passage through said tubular sections including grooves to accommodate said flat strip element such that said flat strip element divides the tubular passage formed by said adjacent tubular transducer sections into two internal passages extending the length of said probe assembly, and means for maintaining adjacent tubular transducer sections in mechanical contact, said means in combination with said elongated flexible support member permitting mechanical flexing of said probe assembly.
Claim 3
Dependent Claim
30 words
A flexible probe assembly as claimed in claim 1 wherein each of said tubular transducer sections includes electrical leads which extend through said internal passages for connection to electrical circuitry.
Claim 4
Dependent Claim
54 words
A flexible probe assembly as claimed in claim 2 wherein said tubular transducer sections are transformers having a primary and secondary winding, the electrical leads associated with said primary windings extending through one of said internal passages, and the electrical leads associated with the secondary windings extending through the other of said internal passages.
