    摘要： 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.

    摘要： A tool, such as a tape measure, including a spring-based retraction system is shown. The tape measure includes a fluid-based retraction speed controller. The speed controller may be formed from a rotor/stator arrangement. The rotor is coupled to the reel and the stator is coupled to the housing opposing the rotor. The rotor converts some rotational energy from tape reel into movement of a fluid (e.g., movement of air, movement of oil, etc. through friction) which acts to slow or limit the retraction/rotational speed of the reel as the retraction spring expands driving the reel during tape blade retraction.

    摘要： A tool such as a tape measure, including a lighting system is shown. The lighting system includes a light source configured to direct light forward and strong enough to act as a flashlight. The tape measure further includes a housing designed to be compact and rugged enough to protect the internal components related to the lighting system from coming loose or suffering damage due to an impact or vibrations.

    摘要： A tool, such as a tape measure, including a spring-based retraction system is shown. The retraction system utilizes an epicyclic gear train coupled between the tape blade winding reel and a rotating arbor or axle within the tape measure. A spiral spring has an outer end coupled to the reel and an inner end coupled to the axle. The gear train may be a reduction gear train such that the axle rotates slower than the reel. By coupling the spiral spring between the gear train input and gear train output, high energy density springs may be used, which may allow for decrease in housing size, increase in tape length or thickness for a given housing size, and/or advantageous retraction speed control.

    摘要： A tool, such as a tape measure, including a spring-based retraction system is shown. The spring-based retraction system includes a motor spring system that drives a tape reel during tape retraction. The output drum of the motor spring system is coupled to the tape reel such that rotation of the reel causes rotation of the output drum. The output drum is located adjacent to the tape reel, and the output drum and tape reel may have a common axis of rotation.
