  • Patent number: 11946736
    Abstract: Various aspects of tape measures with one or more of a sensor, a motor, and a clutch, are shown. The sensors described herein detect, through various mechanisms, the position of the retraction system of a tape measure. The measurements by the sensors may be used to control a motor to adjust an amount of tension in the spiral spring of a tape measure. In various embodiments a motor interacts with the retraction system of the tape measure via a clutch, which moderates an amount of force that the motor can communicate to the retraction system.

  • Patent number: 11945079
    Abstract: A screwdriver includes a main body and a switch. The main body is coupled to a handle and includes a pair of parallel, spaced apart slots, and a pawl positioned in each slot. Each pawl is biased outwardly by a spring. The switch is pivotable relative to the main body, and the switch includes a groove extending along an arcuate portion of an inner surface. Pivoting the switch in a first direction moves the switch toward a first position in which the groove is positioned in-line with the first pawl. When the switch is in the first position, the first pawl extends outwardly from the slot and engages the internal tooth surface such that application of a torque in a first direction drives a shank in the first direction and application of a torque in the second direction causes the shank to ratchet relative to the main body.

  • Patent number: 11949362
    Abstract: Systems and methods described herein provide for controlling a conduction angle applied to a motor, such as a power tool motor. Operations for controlling the conduction angle includes receiving by a motor controller, a desired speed signal, and monitoring a speed of the power tool motor. The operation further includes a motor controller determining an error value between the desired speed signal and the monitored speed and determining a conduction angle signal based on the error value. The operation also includes the motor controller determining whether the conduction angle signal is greater than the error value and increasing a conduction angle of the power tool motor in response to the conduction angle signal being determined to be greater than the error value.

  • Patent number: 11938598
    Abstract: Position sensing related to a component within a power tool. The component within the power tool is, for example, a hammer of an impact mechanism and can include one or more sensible features that allow a controller of the power tool to precisely determine the position, speed, and acceleration of the component. One or more sensors can be used to determine the rotational position of the hammer and the axial position of the hammer. The rotational position of the hammer can then be used to calculate, for example, rotational speed and acceleration of the hammer. With precise determinations of the rotational and axial position of the hammer, the controller of the power tool is able to precisely time the impact between the hammer and the anvil to optimize the impact between the hammer and the anvil (e.g., to maximize energy transfer between the hammer and the anvil).

  • Patent number: 11942880
    Abstract: A power tool, such as a drilling power tool, configured to perform an easy hole start operation upon actuation of a trigger. When the trigger is actuated, the motor is driven at a low speed value. The motor speed is increased to a second speed value during a predetermined time threshold and then driven at the second speed value until the trigger is no longer actuated. In some embodiments, the easy hole start operation may be implemented by an easy hole start switch. In some embodiments, if the easy hole start operation persists for a time greater than a predetermined time threshold, then the motor will shut off.
