US Patent 11650038 Measurement device

A measurement device and/or system for measuring a material length, such as for a human-operated cutting device, includes an elongate band located in a band housing. The elongate band can be extended from the band housing under tension in response to a catch attached to an end of the elongate band grabbing onto an end of a material that is extended beyond an opening at which the catch is located. A computing unit can calculate a length of the material using length data acquired by one or more length acquisition devices, and a measurement interface can provide a user with information corresponding to the calculated length in order to assist the user with accurately cutting the material at a desired location.
