    摘要： A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The controller may opt to reduce the torque applied to shaft to a non-zero value that enables the operator to regain control of the tool.

    摘要： A compliant shifting mechanism can change the operation of a power tool between first and second operating conditions. The shifting mechanism can provide two distinct forces on a gear set during movement of the gear set between the two operating conditions. The shifting mechanism can provide a user with a tactile sensation of the completion of the transition between the two operating conditions without the gear set completing the full transition. A shifting mechanism can automatically complete the change between operating conditions, regardless of an alignment between the gear set and another component. The two distinct forces can be a torsional resistance force and a bending resistance force.

    摘要： A transmission generally includes a shaft member having a continuous cylindrical surface portion longitudinally disposed next to a cylindrical outer surface portion interrupted by longitudinal grooves. A first gear assembly has a first clutch spring that holds a first set of rolling members between lobes that extend from a first output gear. A second gear assembly has a second clutch spring that holds a second set of rolling members between lobes that extend from a second output gear. The first gear assembly and the second gear assembly are configured to move longitudinally along the shaft member to a position where at least one of the first gear assembly and the second gear assembly is engaged for rotation with the shaft member when a value of torque at the shaft member is below a torque threshold value.
