| 摘要 |
A lumber product is described having electronically readable grade and or strength information encoded integrally with the product. The method of making the product is also included within the scope of the disclosure. Information on lumber properties may be determined by known machine or X-ray grading methods. This is transferred to one or more programmable and remotely readable microchips tha t are attached to the individual piece of lumber. The method permits much more information to be included than is conventionally grade stamped on the piece; e.g., compressive or tensile strength, dimensions, prediction error, and other properties.</SDOAB >
