Method for controlling a power driver
First Claim
1. A method comprising:
- providing a driving tool having a driver and a motor assembly, the driver being movable along an axis, the motor assembly including an output member and a pinch member;
operating the motor assembly to move the output member;
determining a kinetic energy level of the moving output member; and
moving the pinch member to drive the driver into contact with the output member to transmit power from the output member to the driver if the kinetic energy level exceeds a predetermined threshold.

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.

12. A method comprising:
-
providing a driving tool having a driver and a motor assembly having a motor, a flywheel, which is driven by the motor, and a pinch member;
operating the motor to thereby turn the flywheel; and
if a rotational speed of the flywheel exceeds a predetermined threshold, moving the pinch member to drive one of the flywheel and the driver into contact with the other one of the flywheel and the driver to transmit energy from the flywheel to the driver and translate the driver along an axis. - View Dependent Claims (13, 14, 15, 16, 17, 18, 20, 21)

22. A driving tool comprising:
-
a driver that is movable along an axis;
a power source for providing an input to the driver and causing the driver to translate along the axis, the power source including a motor;
a sensor for sensing a condition in the power source and generating a sensor signal in response thereto, the condition being indicative of a level of kinetic energy of an element in the power source; and
a controller coupled to the power source and the sensor, the controller being 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. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
