A profiling engine is disclosed. The workpiece taking-out apparatus detects workpieces to find a line of sight of the camera for each workpiece, decides an area for height measurement by a range finder to save height data in the area, and finds an intersection of line of sight data of the camera and height distribution for each detected workpiece to find a posture of the workpiece from the height data around it. The distal end of the kiln may be substantially sealed, and a pressure differential between the distal end and the proximal end may draw moist heated air from the heated chamber toward the exit and entry to preheat andor condition lumber charges traveling through the first chamber. When the insertion force of the bolt is released, the spring member urges the shell segments together so that the internal threads of the shell assembly become engaged with the bolt, and the nut can be tightened on the bolt. An adapter converts a firearm magazine from multiple cartridge capacity to single cartridge capacity, and is configured to be removably coupled to the upper housing to cover the cartridge support member of the housing. The plurality of reservoirs in the first peripheral surface are arranged in an array comprising rows extending substantially parallel to and spaced from one another.
