In accordance with one embodiment of the present invention, there is provided a device for measuring length of feedstock being fed to a tool operated directly by a user. The device includes a body, configured to be removably attached to the tool. The device also includes a display, mounted in the body, and visually accessible to the user. The device also includes a measurement wheel mechanically mounted to the body and configured to be mechanically biased to the feedstock under a condition wherein the body is attached to the tool. The device also includes an encoder coupled to the measurement wheel and configured to generate a signal indicative of angular position of the wheel. The device further includes a processor, disposed in the body, coupled to the encoder and the display and configured to cause the display to show a measure indicative of a length of the feedstock that has been fed to the tool.

There is provided an automatic measurement device that automates a contact type measuring instrument, which is inexpensive and good usability. An automatic measurement device includes a measuring instrument support base portion that supports a measuring instrument and a workpiece holding base portion that holds a workpiece in a measurement region of the measuring instrument. The measuring instrument support base portion includes a measuring instrument holder that holds a fixed element of the measuring instrument and an automatic operation unit attachable to and detachable from the measuring instrument. The automatic operation unit is configured to automate advance and retreat of the movable element of the measuring instrument by a power from a motor.

An electrode loss measuring apparatus includes an electrode which moves in a roll-to-roll state between an unwinder and a rewinder and on which a plurality of reference points are marked at predetermined intervals . The apparatus further includes a reference point detector configured to detect the reference points marked on the electrode, a position measurer configured to derive a position value of the electrode according to a rotation amount of the unwinder or the rewinder and a position value of the corresponding reference point in conjunction with the reference point detector when the reference point detector detects the reference point, and a calculator configured to calculate a loss amount of the electrode by comparing the derived position value of the reference point with a position value of a set reference point when an interval between the reference points is changed due to a loss of a portion of the electrode.

A tool for identifying a correct belt for a system of pulleys from a plurality of prefabricated belts having different lengths is disclosed. The tool may include a belt track attached to a first end portion of a measurement belt. The measurement belt may be wrapped around the system of pulleys. An opposed second end portion of the measurement belt may be disposed adjacent to the belt track which may include a reference indicator. The reference indicator will be aligned to one of a plurality of measurement markings on the second end portion which indicates the correct belt to order from among the plurality of prefabricated belts.

An athletic parameter measurement device worn by an athlete during an athletic activity session includes a housing which attaches to the athlete, a display, a processor associated with the display, and an athletic parameter measurement sensor. During the athletic activity, the device detects, using the sensor, a vertical jump height of the athlete, and displays, during the performance of the athletic activity session, a representation of the vertical jump height on the display.

A measuring tape for measuring the size of limbs or waists is provided with a tape head capable of being stably inserted into a positioning hole during measurement and being automatically ejected out of the positioning hole after measurement, and includes a shell, and a cavity formed in the shell and used for receiving a flexible rule. An elastic switch assembly for clamping the tape head in the positioning hole is disposed at a position, close to the positioning hole, in the cavity. The elastic switch assembly and a leaf spring are disposed in the positioning hole, allowing the tape head to be inserted thereinto, in the shell, such that the tape head can be stably disposed in the positioning hole after being inserted into the positioning hole, and will not slide out of the positioning hole when users observe measure data.

A device for taking a measurement of a dimension of a part of the body of a patient, includes: an electronic tape measure having a portable housing, a winder accommodated in the housing, a tape which is partially wound on the winder and of which a portion, called the “unwound portion”, extends outside the housing, and a measuring module for a measurement, relative to the unwound portion; a consistency control module for checking the consistency of the measurement by at least one consistency rule and at least one context datum; and an alert module for delivering an alert if an inconsistency is detected by the consistency control module.
