Apparatus (101) for supporting a workpiece (201), comprising a frame structure (102) for holding a workpiece (201), a base element (103) for supporting the frame structure (102), and a tool support element (110) for holding a tool. The frame structure (102) comprises lower and upper frame elements (107, 108) between which a workpiece (201) is receivable, and the upper frame element (108) is movable with respect to the lower frame element (107) in a Z-axis direction (106), for clamping a workpiece (102) therebetween. The tool support element (110) is movable with respect to the upper frame element (108) in an X-axis direction (104). The frame structure (102) is movable with respect to the base element (103), and with respect to a workpiece held between the lower and upper frame elements (107, 108), in a Y-axis direction (105). A CNC machine comprising the apparatus (101).

Described herein is an arm supporting exoskeleton, comprising an arm link mechanism. The arm link mechanism comprises a proximal link, a distal link, an arm coupler, and a variable force generator. The distal link is rotatable relative to the proximal link. The arm coupler is adapted to couple an upper arm of a person to the distal link. The variable force generator comprises a first spring and a second spring, configured to create a torque between the proximal link and the distal link. In the first force mode, the variable force generator exhibits a first stiffness rate defined by the first spring that supports the upper arm of the person against gravity forces and. In the second force mode, the variable force generator exhibits a second stiffness rate defined by the first spring and the second spring that supports the upper arm of the person against the gravity forces.

A mobile project center system is presented that includes a center track having a pair of center supports and a pair of legs connected to the center support. A pair of benchtops are connected to the center track and move between an extended position and a retracted position. A pair of braces connect to each benchtop and provide support between the benchtop and the legs. These braces are locked and unlocked using a brace lock controlled by a brace control positioned just below the benchtops. A shelf extends between the opposing pairs of legs that transitions from a folded position and an extended position. The benchtop includes a plurality of openings in a grid pattern that facilitate attachment of various devices such as a joinery block. The system is used to perform a number of operations and converts between a plurality of configurations.

A work table improvement for supporting and fabricating a solid surface is disclosed. The work table has a plurality of table rails, wherein each table rail has a rail top surface and a rail channel running along at least a portion of the rail length on the rail top surface. The table also includes a plurality of channel pucks comprised of a compressible material. Each channel puck has a puck top and a puck tongue, and the puck tongue further includes a necked region, a flared region, and a tapered region. The pucks are constructed to be installed into the rail channel in a direction that is substantially orthogonal to the rail top surface.
