Abstract: A compliant wheel assembly is provided for moving a caliper jaw relative to a caliper spar. The wheel assembly includes a rotary bearing member, a rotary actuation member and a compliant coupling element. The rotary bearing member is coupled to the caliper jaw and may engage the caliper spar. The rotary actuation member is actuated by a user to apply a measuring force. The compliant coupling element is configured to compliantly couple the rotary actuation member to the rotary bearing member. Using the compliant wheel assembly, a user is able to apply a more consistent amount of measurement force than could typically be achieved with a conventional rigid thumb wheel in caliper. In one implementation, a displacement indicator may also be provided that is responsive to the rotational displacement between the rotary bearing and actuation members for indicating an amount of measurement force that is being applied.

Abstract: One or more techniques and/or systems are provided for dynamic data access configuration. For example, a mapping may be maintained for compute nodes of a distributed processing system. The mapping may comprise access permission assignments of at least some compute nodes to shared data segments (e.g., read access and/or write access permissions). The mapping may be updated based upon configuration changes for the distributed processing system (e.g., addition of a new compute node, failure of a compute node, granting or removal of access to a shared data segment for an existing compute node, etc.). The updated mapping may be applied to the distributed processing system during operation of the distributed processing system (e.g., access may be granted to original instances of shared data segments based upon the configuration change; compute nodes and/or the distributed processing system may be kept online and operational while applying the configuration change; etc.).

Abstract: A flexible mount is provided for coupling a force actuator to a caliper jaw. The flexible mount includes a first mounting portion for being coupled to the caliper jaw, a second mounting portion for being coupled to the force actuator, and a flexible element (e.g., a parallel flexure) coupled between the first and second mounting portions. When a force is applied to the force actuator (e.g., by a user pushing on a thumbwheel) along the measuring axis direction, the flexible element flexes to generate a measuring force that is applied to the caliper jaw. The use of the flexible mount results in more control and a better feel for a user when attempting to exert control to provide a desired amount of force during a measuring process. The flexible mount may also utilize a fastening configuration that is compatible with existing mounting features on existing caliper jaws.
