Abstract: Methods for reducing warp potential of lumber derived from a raw material, such as a log or stem are provided. The methods involve examining the log or stem for shrinkage properties and/or properties of spiral grain. The location of the shrinkage properties and/or properties of spiral grain determine how the log is oriented relative to a cutting device. In another embodiment, these characteristics determine what cutting pattern is selected for creating the lumber. In the case of a stem, these characteristics determine how the stem will be bucked.

Abstract: Methods are provided for estimating the dimensional stability of a wood product from simple algebraic functions of moisture, shrinkage rates and grain angles observed on outer surfaces. The methods may employ single or multiple sensor group measurements.

Abstract: Systems and methods are provided for detecting the potential of a wood sample, such as a board, to stay on grade, i.e., resist warp, after it is put into service and/or its moisture has re-equilibrated with the surrounding environment. The systems and methods include various sensor technologies and subjection of obtained data to various models, algorithms, and/or other mathematical formulas.

Abstract: Embodiments of the present invention quantify lengthwise shrinkage to a higher degree of accuracy over currently known methods by employing reactive force values, such as stiffness measurements, in conjunction with motive force values, such as chemical composition, of the wood product.
