Patent number: 11946736Abstract: 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.Type: GrantFiled: September 8, 2022Date of Patent: April 2, 2024Assignee: Milwaukee Electric Tool CorporationInventors: Gareth J. Mueckl, Scott Earl McKinster

Patent number: 11938598Abstract: 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).Type: GrantFiled: September 28, 2022Date of Patent: March 26, 2024Assignee: Milwaukee Electric Tool CorporationInventors: Jacob P. Schneider, John S. Dey, IV, Timothy R. Obermann

Patent number: 11933380Abstract: A clutch mechanism is used in a rotary power tool having a motor. The clutch mechanism includes an input member to which torque from the motor is transferred and an output member co-rotatable with the input member. The output member defines a rotational axis.
