  • Method and apparatus for assessing or predicting the characteristics of wood
    Patent number: 7603904
    Abstract: A method and apparatus for determining a characteristic, such as the stiffness, of a portion of a wood specimen characterised by the steps of a) producing an acoustic signal in the wood specimen part way along the length of the wood specimen, and b) sensing a response in the wood specimen part way along the length of the wood specimen including a reverberation from a first end of the wood specimen, and c) calculating a characteristic of a portion of the wood specimen from analysis of the sensed response. A related method and apparatus may be used to determine a characteristic of a portion of a tree stem during harvesting of a tree and the characteristic used to optimise the value of a log cut from the stem.
