Abstract: A fastener driving tool and an adapter for a fastener driving tool are described herein for permitting accurate placement of fasteners with respect to an edge of a board (e.g., a top edge of a siding board). The adapter may include an adapter body having a central opening for receiving a head of a fastener driving tool and two or more pins positioned in the adapter body. At least two of the pins are positioned in the adapter body such that, when the central opening receives the head, the pins are equidistant from a center of a barrel through which the fastener driving tool drives fasteners.

Abstract: A inductorless method and apparatus for driving electroluminescent (EL) panels enables fabrication of an integrated circuit that provides a complete EL panel driver solution in one package. The high voltage required to drive the EL panel is generated by a plurality of charge pump circuits. A multi-stage charge pump may be used to provide a high voltage power supply that does not require an external capacitor to store energy for the power supply.
