Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
104 words
A lens arrangement for focusing and defocusing sonic and ultrasonic energy transmitted between sonic and ultrasonic transmitting and receiving stations comprising a plurality of ultrasonic and sonic fibers connected between said transmitting and receiving stations and each fiber being simultaneously end driven by the same transducer at one end and connested to simultaneously end drive a receiving transducer at the other end, and said plurality of ultrasonic and sonic fibers formed of first and second groups which are each formed of different materials which have different sonic and ultrasonic energy transmitting characteristics, said groups being geometrically arranged to provide said focusing and defocusing action.
Claim 2
Dependent Claim
104 words
A lens arrangement for focusing and defocusing sonic and ultrasonic energy transmitted between sonic and ultrasonic transmitting and receiving stations comprising a plurality of ultrasonic and sonic fibers connected between said transmitting and receiving stations and each fiber being simultaneously end driven by the same transducer at one end and connested to simultaneously end drive a receiving transducer at the other end, and said plurality of ultrasonic and sonic fibers formed of first and second groups which are each formed of different materials which have different sonic and ultrasonic energy transmitting characteristics, said groups being geometrically arranged to provide said focusing and defocusing action.
Claim 3
Dependent Claim
31 words
A lens arrangement for transmitting sonic and ultrasonic energy between stations according to claim 1 wherein said first group of said fibers differ in density from said second group of fibers.
Claim 4
Dependent Claim
34 words
A lens arrangement for transmitting sonic and ultrasonic energy between stations according to claim 1 wherein said receiving station includes a sonic and ultrasonic receiving member to which said plurality of fibers are connected.
Claim 5
Dependent Claim
35 words
A lens arrangement for transmitting sonic and ultrasonic energy between stations according to claim 3 wherein sonic and ultrasonic receiving lens arrangement is a flat plate to which the ends of said fibers are affixed.
Claim 6
Dependent Claim
52 words
A lens arrangement for transmitting sonic and ultrasonic energy between stations according to claim 4 wherein said ends of first group of fibers are affixed to said plate at positions further from the center of said plate than the position through which the ends of said second group of fibers are affixed.
Claim 7
Dependent Claim
45 words
A lens arrangement for transmitting sonic and ultrasonic energy between stations according to claim 5 wherein said ends of said first group of fibers are fastened generally in a circle and said ends of said second group of fibers are generally fastened within said circle.
Claim 8
Dependent Claim
34 words
A lens arrangement for transmitting sonic and ultrasonic energy between stations according to claim 4 wherein the ends of said first group and second group of fibers are uniformly mounted to said flat plate.
Claim 9
Dependent Claim
28 words
A lens arrangement for transmitting sonic and ultrasonic energy between stations according to claim 6, including a sonic and ultrasonic amplifier connected to said first group of fibers.
