A calibration control device for being coupled to a measuring device such as a caliper, micrometer, or gauge is provided. The calibration control device includes a circuit portion and couples to a coupling feature on the measuring device. A calibration limit portion defines a parameter limit as related to a usage limit for which the measuring device is certified as calibrated. A controller operates a host-side data connection portion of the calibration control device to output measuring data in a first mode when the usage limit is not exceeded, and operates the calibration control device to perform a calibration limit function when the usage limit is exceeded. The calibration limit function may include stopping the output of the measuring data through the host-side data connection or providing an out-of-calibration warning to the host, or the like.

A vernier caliper is a measuring instrument provided with a main scale and a slider that is slidably provided along a longitudinal direction of the main scale. The slider is provided with an operating part for a user to put his/her finger thereon so as to operate the same. The operating part is provided with a haptic notification means that notifies, through a haptic sense of the finger, that a predetermined measuring pressure has been reached by generating a resistance with respect to the finger by moving in association with the operation of the finger and by causing the resistance to change at a predetermined movement position.

A measuring tool for disc brake device brake pad, which includes a base, a first tube, a second tube, a front rod, a measuring rod, and a spring, wherein the first tube is configured at the front end of the base, the first tube is perforated with a sighthole. The second tube is pivoted in the first tube, and a marking is formed on the exterior of the midsection of the second tube. The front rod is configured at the front end of the second tube, and a pivot hole axially penetrates the front end of the front rod. The measuring rod pivotal penetrates the front rod, the second tube, and the first tube. The rear end of the measuring rod is inserted into the center of the front end of the base. A contact pin extends in a curved sideward direction from the front end of the measuring rod, and the contact pin abut against the front end of a protruding portion. The spring is disposed in the interior of the second tube, and the two ends of the spring respectively abut against the front rod and the base.

One or more specific embodiments disclosed herein includes an apparatus for manually measuring the distance between a first and second point, comprising: a first and second member that is positioned adjacent to the first member, wherein the first member is capable of sliding with respect to the second member in an axial direction and wherein each of the first and second members is substantially straight and has at least two outer longitudinal sides that are substantially straight and substantially parallel to one another, a first replacement tip receiver at a first location between the two outer longitudinal sides of the first member, wherein a first tip can be removably coupled to the first member, and wherein the first tip includes a first tip point capable of corresponding to the first point of the distance to be measured, and a first scale that provides a first distance measurement.

A compliant thumb wheel assembly coupled to a caliper jaw that moves along a caliper scale member along a measuring axis direction in a caliper comprises a thumb wheel, a compliant element, and a thumb wheel mounting portion rigidly coupled to the caliper jaw. The compliant element is configured to locate the thumb wheel in an operational arrangement for driving the caliper jaw while at the same time transmitting forces between the thumb wheel and the thumb wheel mounting portion by elastic deformation. When a force is applied to the thumb wheel along the measuring axis direction, the compliant element flexes such that the thumb wheel displaces along the measuring axis direction relative to the thumb wheel mounting portion and the caliper jaw, and generates a measuring force that depends on that relative displacement and which is applied to the caliper jaw along the measuring axis direction.

A device for measuring the height of a child, standing on a floor, near a wall, comprising a housing having a plastic molded front panel that includes a track member, and a molded pack panel attacked to the backside of said front panel; said housing attached to a wall. The housing front panel has a central space and a mirror to keep the attention of the child during the measuring process, and a visible scale and a carriage, each attached to the track member, with the carriage being vertically movable along the track member. The carriage can be manually moved by a user to correspond to the top level of the child's head, an indicator on the carriage points to a location on the visible scale indicating the height of the child. The front panel has a flat vertical surface parallel and next to the vertical track for a user to place indicia with a marker next to the carriage with child height measurement information.
