摘要： A method for controlling a driving tool having a power source, a driver, an actuator, a follower, and a control unit. The power source includes a motor and a flywheel that is driven by the motor. The actuator is configured to selectively move the follower to push the driver into frictional engagement with a surface of the flywheel. The control unit is configured to selectively activate the electric motor and the actuator. The control unit includes a speed sensor that is configured to sense a rotational speed of an element of the power source and produce a speed signal in response thereto. The method includes: directly determining a rotational speed of an element in the power source; controlling electrical power provided to the motor based on the rotational speed of the element in the power source to cause the flywheel to rotate at a predetermined speed; and actuating the actuator when a set of actuating criteria has been met, the set of actuating criteria not including a rotational speed of the element.

摘要： A battery charger is provided for implementing a charging method having a stepped output current. The battery charger includes: a power supply circuit that receives an AC input signal and outputs a DC output signal. The power supply circuit includes a power supply controller configured to receive a feedback signal indicative of current being output by the power supply circuit via an amplifier and operates to control current output by the power supply circuit in accordance with the feedback signal. A charger controller is interfaced with the power supply controller to implement a charging method having a stepped output current. The charger controller may set the output current level by adjusting gain of an operational amplifier having a negative feedback configuration with the feedback signal input to a non-inverting input terminal of the operational amplifier, where the charger controller sets the output current level by changing the resistance at an inverting input terminal of the operational amplifier.

摘要： A battery pack can include a temperature sensor that can provide an output that is indicative of a temperature associated with the battery pack. A battery management unit can directly measure the temperature sensor when the battery pack is by itself or engaged with a tool. A charger can directly read the temperature sensor when the battery pack is engaged with the charger. Thus, the temperature sensor can be shared by the battery pack and the charger. The battery pack can utilize a same terminal that provides access to the temperature sensor to indicate a stop-charge signal. The charger can read the stop-charge signal on the same terminal used to directly access the temperature sensor.

摘要： 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.
