Systems, methods, and apparatus for positioning and/or processing items, such as workpieces. The systems, methods, and apparatus may include or use a linear positioner forming a track. In some embodiments, the linear positioner may include a carriage configured to be driven along the track to a desired position, in response to a signal(s), such as a radiofrequency signal(s), received from a computer, which may be a general-purpose, handheld computer, such as a phone or tablet. In some embodiments, the linear positioner may comprise a shuttle including a motor and a carriage, and may be configured to drive itself as a unit along the track. In some embodiments, the track may include a rack having a linear array of teeth formed by two or more frame sections, such as table sections, coupled end to end, with each support section providing a segment of the rack.

An ascent-detecting air supply port (33), a descent-detecting air supply port (43), and an air discharge port (44) are provided to a housing (2). The ascent-detecting air supply port (33) is communicatively connected to an air outlet (38) by an ascent-detecting air passage (39). The descent-detecting air supply port (43) is communicatively connected to the air discharge port (44) by a descent-detecting air passage (45). The descent-detecting air passage (45) is closed by a valve mechanism (49) including: a valve surface (50) provided on a piston portion (15); and a valve seat (51) provided on an inner surface of the housing (2), when an advance piston (14) is retracted to a lowered position.

A sliding compound miter saw slide device allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The sliding saw slide device integrates an adjustment or alignment mechanism configured to move an upper base portion of the saw base relative to a lower base portion of the saw base. In addition, a sliding saw stand allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The sliding saw stand integrates an adjustment or alignment mechanism configured to move an upper miter saw mount member/plate relative to the saw stand base/base frame.

A truss jigging system has an elongated table forming a support plane and formed with a plurality of parallel slots extending between the two long edges. The table has a plurality of the following: locating pins, carriages, endless belts, idler wheels, and, drive wheels. Each endless belt is strung around a respective one of the idler wheels and a respective one of the drive wheels to form a pair of elongated runs, one run being an elongated return run and the other run having a respective one of the carriages affixed thereto and coursing through a respective slot such that, driving the drive wheel moves the locating pin back and forth along the front to back axis of the respective slot.
