A deformation detection apparatus includes a cell movement-control assembly to handle a linear motion and a rotational motion of a battery cell, a body that supports the cell movement-control assembly, a digital micrometer, and control circuitry. The control circuitry controls a displacement of the battery cell between a first position and a second position along a longitudinal axis through a scanning region of the digital micrometer and a plurality of rotational positions of the battery cell at a plurality of charge states and a plurality of discharge states. The control circuitry measures a plurality of outer diameter values of the battery cell for a plurality of linear positions and a plurality of rotational positions along the longitudinal axis of the battery cell and determines a change in a geometrical shape (deformation and/or strain) of the battery cell for the plurality of linear positions and the plurality of rotational positions.

A measuring instrument is configured to detect a displacement of a contact point provided to be movable and to digitally display a measured value on a display unit provided on an outer surface of a case. The measuring instrument includes an input unit. The input unit is provided on the outer surface of the case and is configured to allow a user to input to the input unit through a manual operation. The input unit includes a sensor which is configured to detect an amount of operation and a speed of operation. The amount of operation is converted into a conversion value in view of the speed of operation and then is displayed on the display unit.

Devices and methods for driving a micrometer are provided. The device includes a body, a collet, a motor, and a controller. The body is configured to be coupled to a frame of the micrometer. The collet is configured to be coupled to a ratchet of the micrometer and to rotate the ratchet. The motor is coupled to the collet and rotates the collet to rotate the ratchet. The controller controls operation of the motor.

A water-holding cup for use in connection with a hydrostatic system for measuring with precision, a level normal to gravitation of a surface, said cup comprising: a cup height h thereof from a bottom to a top of said cup when said cup is resting upon the surface, which cup height h is known a priori within acceptable measurement errors; mirroring on a bottom surface of said cup; and at least two water outlets for fluidically interconnecting said cup with other like-cups, said outlets oriented at a fitting angle of at least five (5) degrees downward.

Methods and equipment suitable for measuring dimensions of a cylindrical body including systems having a housing and means for supporting the housing relative to an arcuate surface of the body. The supporting means comprises at least two wheels having axes of rotation oriented so that engaging the arcuate surface of the body with the two wheels causes edges of the two wheels to contact the arcuate surface at two terminals spaced apart by a length of a chord lying in a cross-section plane of the body. Measurement means is mounted to the housing for contacting a surface point of the body located within the length of the chord of the body, and means is provided for determining the diameter of the body based on the length of the chord determined by the two wheels and a height of the chord ascertained with an output of the measurement means.

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.
