An error compensation device includes at least one photographing module, a comparison module and a compensation module compensation module. The photographing module establish a space coordinate system relative to the object and comprises a first photographer and a second photographer which respectively photograph a first non-deformed laser speckle image on a first surface and a second non-deformed laser speckle image on a second surface, the first surface differs from the second surface by an azimuth. The comparison module respectively compares the first non-deformed laser speckle image before and after the displacement with the second non-deformed laser speckle image to calculate a displacement value between the two surfaces. The compensation module controls the movement of the object according to the displacement value. The error compensation utilizes the displacement of the non-deformed laser speckle image to obtain the absolute error of the object and compensate the error.

A measurement, calibration and compensation system for machine tool includes a first positioning base; two first speckle image sensors for sensing speckle positions of an object holding unit at a first XY plane and a first XZ plane of the first positioning base before and after the machine tool is started for machining; a second positioning base; two second speckle image sensors for sensing speckle positions of a cutter holding unit at a second XY plane and a second YZ plane of the second positioning base before and after the machine tool is started for machining. Thus, the thermal expansion at all axes of the machine tool can be measured in a simplified and low-cost way, and the absolute positioning coordinates of all axes of the machine tool can be calibrated in real time to avoid reduced positioning accuracy due to the thermal expansion of the multi-axis machine tool.

An information handling system (IHS) chassis defines a component housing. An IHS component is located in the component housing. The IHS component defines a module channel, a module chassis locating slot adjacent the module channel, and a pair of module chassis securing apertures adjacent the module channel. The IHS component includes a module chassis retaining surface that is spaced apart from the module channel. A module chassis is located in the module channel, includes a retaining wall that engages the module chassis retaining surface and a locating member that extends into the module chassis locating slot, and defines a module housing. The module chassis is secured to the component through the pair of module chassis securing apertures. A latching module is located in the module housing and secured to the module chassis. The latching module engages the IHS chassis to resist removal of the IHS component from the component housing.

Latching module mounting system

A securing system includes a base member. A display member is rotatably coupled to the base member by a shaft. A locking member is operable to move axially relative to the shaft and engage the display member in order to restrict the display member from rotating relative to the base member. The base member and the display member may be part of an information handling system (IHS). A lock including a cable that is coupled to a stationary object may be used to secure the IHS to the stationary object and prevent the use of the IHS by positioning the lock in the base member in order to move the locking member such that it engages the display member.
