Patent ID: 6871153

Claim:
A dynamic calibration system for monitoring a direct drive non-pulse tool comprising: a means for measuring air pressure of a non pulse, direct drive tool and converting the air pressure into an electrical signal representative of the air pressure; a means for electrically computationally processing the electrical signal into another signal representative at least one parameter corresponding to a condition of the tool being monitored which is a function of air pressure; a programmed microprocessor configured to identify a portion of the signal representative of the air pressure corresponding to the parameter; wherein the programmed microprocessor is configured to identify and store the parameter of a first threshold air pressure to begin monitoring the parameter of a cycle; wherein the programmed microprocessor is configured to identify and store the parameter of a second air pressure to identify a portion of the signal representative of the air pressure of the tool driving a fastener; wherein the programmed microprocessor is configured to identify the air pressure associated with the tool running the fastener prior to clutch engagement; wherein the programmed microprocessor is configured to identify a peak air pressure associated with the tool as a clutch shut off; wherein the programmed microprocessor is configured to identify and store a portion of the air pressure as a calibration value for the parameter of the second air pressure; and wherein the programmed microprocessor is configured to identify and store the parameter of a dynamic threshold corresponding to the calibration value.
