Patent attributes
A fastener driving device is disclosed. The device includes a fastener depletion sensing system that is constructed and arranged to allow normal operation of a power system contained within the device so long as a supply of fasteners provided by a magazine assembly is such that more than a predetermined number of fasteners are in a feed track and/or a drive track within the device. The fastener depletion sensing system is operable when the predetermined number of fasteners in the feed and/or the drive track is reached to provide a tactile indication to the user that the predetermined number of fasteners has been reached, and permitting the user to either cease further operation following the indication or complete the operation following the indication.
