摘要： A dry fire lockout assembly for a fastener driving device includes a bypass feature. A link is movably mounted to an upper contact arm and interconnected with a lower contact arm when the link is in a first orientation. The link includes a dry fire lockout portion. A dry fire lockout portion of a lifter is configured to engage the dry fire lockout portion of the link, when a supply of fasteners in the fastener driving device is less than a predetermined number of fasteners, and move the link against the bias of the biasing member to a second orientation in which the link is not interconnected with the lower contact arm.

摘要： A spike filter circuit (11) has an input (12) for receiving an input signal comprising data bits and an output (13) for providing a filtered output signal. A data bit is characterized by a voltage magnitude and a minimum time period. The spike filter circuit (11) filters out any signal applied to the input (12) that has a period less than the minimum time period of a data bit. The spike filter circuit comprises a pulse width sense circuit (14), a Schmitt trigger (16), and a delay circuit (17). The pulse width sense circuit (14) is responsive to the input signal and filters out signals having a period less than the minimum time period of a data bit. The Schmitt trigger (16) is responsive the pulse width sense circuit (14), has predetermined threshold voltages to increase noise immunity, and buffers the output of the pulse width sense circuit (14). The delay circuit (17) is responsive to the filtered output signal and provides a signal delayed by a predetermined time to a feedback input of the pulse width sense circuit (14). The signal provided by the delay circuit (17) inhibits the pulse width sense circuit (14) from sensing a data bit (having an opposite logic level to that at the output (13)) for the delay of the predetermined time of the delay circuit (17).

摘要： A fastener driving device includes a housing having an engine receiving portion and a handle portion. A reservoir is configured to receive a gas having a pressure greater than atmospheric pressure and is at least partially located in the handle portion. A dust blower is configured to allow gas in the reservoir to be selectively communicated to atmosphere through an outlet in the engine receiving portion of the housing. The dust blower includes a passageway extending from the reservoir to the outlet in the engine receiving portion, the passageway at least partially circumnavigating the cylinder of the drive engine, and an actuator configured to selectively open and close the passageway so that when the passageway is open, gas from the reservoir is communicated from the reservoir to the outlet, and when the passageway is closed, the gas from the reservoir is not communicated from the reservoir to the outlet.
