Abstract: A lumber check grader-actuatable interface enables a check grader to interact with grade-quality measured boards of lumber conveyed along a flow path and passing in front of the check grader. The interface accurately and continuously tracks the location of each board in front of a check grader and tracks the location of the check grader's hands relative to the boards. Gestures can, therefore, be used for a selected board to perform additional actions, such as changing the grade or changing the trims. The interface enables a check grader to walk alongside and keep pace with a board of interest as it is transported and to provide feedback to the interface about a needed change for the board of interest. By knowing which board is of interest to a check grader, the interface can display additional information for only that board without overwhelming the check grader with non-stop information overload.

Abstract: A grain angle sensor system for measuring grain angle direction of surface fibers of a wood object with respect to at least one of a surface plane direction or a transverse direction, such as a dive angle, or with respect to both the surface plane and transverse direction. The system includes multiple laser diodes and photosensor detectors integrated into an electro-optical assembly that can sequence the firing of the lasers to minimize crosstalk. An exemplary assembly includes an enclosure housing an electronic control board connected to circuit cards containing multiple laser diodes and multiple photosensor detectors.
