Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
A wave force transducer comprising: a. a shell adapted to be mounted adjacent to and at least partially enclose a support column; b. a set of flexures connected between and parallel to said shell and support column and adapted to permit lateral movement of said shell with respect to said support column and prevent vertical or tilting movement of said shell with respect to said support column; and c. at least one pair of hydraulic load cells located opposite each other on said shell, connected between said shell and support column and by rigid tubing to opposite sides of a hydraulic differential pressure transducer and adapted to measure the total wave force acting upon said shell.
Claim 2
Dependent Claim
116 words
A wave force transducer comprising: a. a shell adapted to be mounted adjacent to and at least partially enclose a support column; b. a set of flexures connected between and parallel to said shell and support column and adapted to permit lateral movement of said shell with respect to said support column and prevent vertical or tilting movement of said shell with respect to said support column; and c. at least one pair of hydraulic load cells located opposite each other on said shell, connected between said shell and support column and by rigid tubing to opposite sides of a hydraulic differential pressure transducer and adapted to measure the total wave force acting upon said shell.
Claim 3
Dependent Claim
21 words
A wave force transducer as stated in claim 1 wherein four of said hydraulic load cells are located at 90* intervals.
Claim 4
Dependent Claim
167 words
A wave force transducer comprising: a. a shell, adapted to be mounted adjacent to and encircling a support column, said shell having a door section adapted to permit installation of said shell around said support column; b. a set of flexures connected between said shell and support column and adapted to permit lateral movement of said shell with respect to said support column and prevent vertical or tilting movement of said shell with respect to said support column, each of said flexures consisting of a rod having a length of reduced cross section adjacent each end with one of said rod connected to said support column adjacent one end of said shell and the other end of said rod connected to the other end of said shell; and c. four hydraulic load cells are located at 90* intervals around said shell and each pair of hydraulic load cells spaced apart by 180 degrees are connected by rigid tubing to opposite sides of a hydraulic differential pressure transducer.
Claim 5
Dependent Claim
167 words
A wave force transducer comprising: a. a shell, adapted to be mounted adjacent to and encircling a support column, said shell having a door section adapted to permit installation of said shell around said support column; b. a set of flexures connected between said shell and support column and adapted to permit lateral movement of said shell with respect to said support column and prevent vertical or tilting movement of said shell with respect to said support column, each of said flexures consisting of a rod having a length of reduced cross section adjacent each end with one of said rod connected to said support column adjacent one end of said shell and the other end of said rod connected to the other end of said shell; and c. four hydraulic load cells are located at 90* intervals around said shell and each pair of hydraulic load cells spaced apart by 180 degrees are connected by rigid tubing to opposite sides of a hydraulic differential pressure transducer.
