Title:

SYSTEM FOR AND METHOD OF PERFORMING EVALUATION TECHNIQUES ON A LOG OR ROUND TIMBER

Document Type and Number:

WIPO Patent Application WO2002060662

Kind Code:

A3

Abstract:

A system for and method of evaluating a log. The system (100) includes an analysis module (110) having at least one input terminal (120) connectable to the at least one input device (105). The at least one input terminal (120) is operable to receive at least one signal representing at least one measured property of the log and at least one determined parameter of the log determined in response to an energy being applied to the log. The analysis module (110) further includes a processor (130) coupled to the at least one input terminal (120). The processor (130) determines a predictive modulus of elasticity of the log based at least in part on the at least one measured property and the at least one sensed parameter. The analysis module (110) also includes an output terminal (125) coupled to the processor (130) and connectable to an output device (115). The output terminal (125) transmits a third signal representing the predictive modulus of elasticity.
