| 20080237096 | Methods for determining pith direction and location in lumber - Methods are provided for determining a location of a pith along a length of a wood sample. The methods may comprise the steps of: determining pith direction; selecting two areas of the wood sample at which two or more chords of a ring can be defined; bisecting the chords to define a line perpendicular to the chords; and locating at least one intersection point for two or more of the bisecting perpendicular lines. | 10-02-2008 |
| 20080246971 | Methods For Using Light Reflection Patterns To Determine Diving Angle Of Grain - Methods are provided for using light reflection patterns to determine various properties of fibrous materials, such as wood. More specifically, the present invention relates to methods for determining a dive angle for grain. Further, the present invention relates to methods for using information in T2 plots, combined with knowledge of the microstructure of a wood sample surface, to find pith location and/or ring curvature. | 10-09-2008 |
| 20080283151 | Warp Stable Wood Product And Methods For Detecting The Same - A warp stable wood product and methods for detecting the same are provided. The wood product may be sorted based on its morphology, microstructure, macrostructure, and/or chemical composition properties being substantially symmetric relative to at least one or more cross-sectional centroids of the wood product, thereby imparting warp stability. | 11-20-2008 |
| 20100158309 | DETERMINING WOOD CHARACTERISTICS USING ANNUAL RING IMAGES FROM LUMBER FACES - Methods are described for predicting the percentage of latewood and specific gravity of lumber independent of moisture content using image analysis of the lumber surfaces. | 06-24-2010 |
| 20100230310 | Warp Stable Wood Product Package and Methods for Sorting a Wood Product - The present disclosure includes a wood product package comprising a plurality of wood products having a performance attribute. The performance attribute of the wood products is certified in statistical terms based on a degree to at which at least one of a morphology, microstructure, macrostructure or chemical composition property remains substantially symmetrical about a cross-sectional centroid of each of the wood products. Each of the plurality of wood products have a cross-sectional centroid. The plurality of wood products each have a property that is substantially symmetrical about the cross-sectional centroids. The property is related to morphology, microstructure, macrostructure, and chemical composition. Further aspects of the disclosure are directed towards methods for sorting wood products. | 09-16-2010 |
| 20100332438 | Methods for Predicting Warp of a Wood Product Produced from a Log - The present disclosure relates to methods for predicting warp of a wood product produced from a log. Some embodiments include performing a three dimensional scan of the log to obtain geometric data, using the geometric data to construct a log profile, partitioning the geometric data into geometric components, removing one or more selected geometric components to create one or more residual grid profiles, deriving geometric statistics from the one or more residual grid profiles or from the log profile, and entering the geometric statistics into a model for predicting warp of the wood product. The geometric statistics may include orientation dependent and orientation independent statistics. | 12-30-2010 |
