    Abstract: A scratch strain gauge has an annular target guided into its recording position where it cooperates with a scratch element on a scratch arm to indicate strains of opposite senses. The gauge has a guide adjacent one edge of a plate on which rollers are mounted for rotatably mounting the target in cooperation with brushes. The guide cooperates with a groove in the periphery of the target to insure that the groove receives one of the rollers, then the brushes, and finally the other roller as the target is inserted into its recording position. Ears, which are disposed above the rollers and extend outwardly beyond the rollers to overlie portions of the target when the target is in its recording position, aid in insuring that the target is seated on the roller tongues when disposed in its recording position.

    Abstract translation: 刮擦应变仪具有引导到其记录位置的环形目标，其中它与暂存臂上的划痕元件配合以指示相反感的应变。 该计量器具有邻近板的一个边缘的引导件，在该边缘上安装有滚子，用于与刷子一起可旋转地安装目标。 引导件与目标周边的凹槽配合，以确保凹槽容纳其中一个滚子，然后刷子，最后另一个滚子作为目标插入其记录位置。 耳朵，当目标处于其记录位置时，它们设置在滚子上方并向外延伸超出目标的部分，有助于确保目标在设置在其记录位置时位于滚子舌上。

    Abstract: Embodiments of the invention include a fracture ring sensor and a method of using the same to detect out of tolerance forces. Aspects of the invention include a product having a defined an out of tolerance force, a fracture ring sensor, and a mounting assembly coupling the fracture ring sensor to the product. The fracture ring sensor is patterned with a conductive trace and is manufactured to break when subjected to a predetermined amount of force. The predetermined amount of force is substantially equal to a percentage of the out of tolerance force of the product.

    Abstract: In one aspect, a load cell includes an elastic body, first optical unit, second optical unit, detector, and computation unit. The first optical unit has a light source, a first diffraction grating on which light from the light source is incident, and a light-receiving unit. The first optical unit is fixed to a first end portion of the elastic body and arranged within a hollow portion of the elastic body. The second optical unit has a second diffraction grating on which diffracted light from the first diffraction grating is incident to generate interference light. The second optical unit is fixed to a second end portion of the elastic body and arranged within the hollow portion. The detector detects the interference light. The computation unit computes a relative displacement amount of the second diffraction grating relative to the first diffraction grating on the basis of a signal obtained by the detector.

    Abstract: The present subject matter discloses a method of measuring a peak load, including the steps of placing an indenter between a first surface and a second surface, exerting a load on at least one of the first and second surfaces, measuring at least one of a width, depth, radial chord length, and cross-sectional area of an indentation formed by the indenter in at least one of the first and second surfaces; and converting the measured parameter into a load value. Certain methods further include the steps of converting the measured parameter into a load per length value and obtaining a load value by integrating along a circumferential length of the indentation. In still other methods, the exerted load is a compressive load.
