  • Patent number: 8347978
    Abstract: A driving tool having a driver, a power source, a sensor and a controller. The power source selectively provides an input to the driver to cause the driver to translate along an axis. The sensor senses a condition in the power source that is indicative of a level of kinetic energy of an element in the power source and generates a sensor signal in response thereto. The controller is coupled to the power source and the sensor and is responsive to the sensor signal for deactivating the power source to inhibit the power source from providing the input to the driver when the level of kinetic energy of the element in the power source is below a predetermined threshold. A method for operating a driving tool is also provided.

  • Patent number: 8313012
    Abstract: A controller 50 has a single-driving mode/continuous-driving mode changeover switch 233 for performing fastener driving operation in a single driving mode or a continuous driving mode. In a case where the single-driving mode/continuous-driving mode changeover switch 233 instructs a single driving mode, the controller 50 causes a driver blade 3a to perform fastener driving operation when both a trigger switch 5 and a push lever switch 22 are switched, by switching operation, from the one switch status to the other switch status (e.g., the ON status). Consequently, fastener driving operation is made possible regardless of sequence of actuation of the trigger switch 5 and the push lever switch 22.

  • Publication number: 20120248167
    Abstract: Systems and methods are provided for detecting misfire of a surgical staple cartridge and for indicating such misfire to a user on a user interface. An actuation force applied to a staple cartridge is measured and compared to a threshold actuation force. In response to the comparison, a controller determines if there has been a misfire of the surgical staple cartridge. A determination that misfire has occurred is made when the measured actuation force is greater than a maximum threshold force or less than a minimum threshold force, and under such circumstances, the controller terminates the staple firing sequence.
