A reconfigurable power circuit () includes a single one-way DC to DC power converter (). The reconfigurable power circuit is configurable by a digital data processor as one of three different power channels (, and). Power channel () provides output power conversion. Power channel () provides input power conversion. Power channel () provides bi-directional power exchange without power conversion.

A machine control and data logging station, intended for use with a saw or other machine tool, features a processor which monitors a number of input lines, a real time clock and time stamp function. Any change of input signals from the machine tool will be recorded in flash memory. Both wired and wireless outputs may read the memory at any given time. Optionally, hardware or software data communication encryption may be employed to provide increased confidentiality and security. The station continually monitors sensor inputs and can react automatically to emergency-stop the machine tool upon sensing a dangerous condition.

A safety system for a rotary saw or other dangerous machine tools features a flesh-sensing circuit (), located on a safety guard () surrounding a dangerous machine part, which generates an electronic signal to trigger emergency stopping of the machine before the operator can contact the dangerous machine part. The stopping means preferably employs DC injection, winding current direction reversal and/or electromagnetic motor braking, in the event of detection of operator contact with the safety guarding device. The system is adapted to be used both with newly-manufactured machine tools and by retrofitting onto previously-manufactured machine tools, by in-the-field modifications.

An improved health and safety system for a table saw includes one or more of: a blade guard that protects the operator from the saw blade, and contains and collects sawdust; a proximity detector and emergency saw motor braking means for use in connection with such blade guard; an anti-kickback device for use in connection with such blade guard, a rip fence adapter for use in connection with such a blade guard, and hoses and fittings to connect the dust containment and collection system of said blade guard to a shop dust collection blower or vacuum system. The system protects the saw operator from potential traumatic injury to a hand, and from ingesting potentially carcinogenic sawdust.

A tool for driving staples or nails and simultaneously providing reinforcement therefore. The tool is particularly useful in installing roofing material, although it has equal utility in attaching labels, tags and the like to shipping cases, and siding to buildings, and other purposes. In a preferred embodiment, the tool is provided with a handle which is long enough that a workman may operate the tool without bending over any material amount. The staple or nail driving mechanism may be of the hand-driven type or may be air, electric or spring operated. Connected to the housing of the driving mechanism is a magazine containing a considerable number of fastener reinforcing elements, such as thin metal discs, through which the staple or nail is driven in the same stroke used to drive such fastener into the object to be fastened. In one embodiment of the invention, a coil of thin sheet metal is rotatably disposed within a housing carried by the driving mechanism housing, the leading edge of the strip being fed into position and sheared into tab form, the staple or nail then being driven through the tab.
