Abstract: The present disclosure provides an exoskeleton mechanism for supporting a joint. The exoskeleton mechanism includes a brace having a first arm and a support arm, the support arm pivotably connected to the first arm. The exoskeleton mechanism further includes a spring secured to the first arm, the spring having a first length at an equilibrium position and a second length at a displaced position, a spring force generated by the spring when the spring is in the displaced position. Additionally, the exoskeleton mechanism has a cable having a first end and a second end, the first end coupled to the support arm and the second end coupled to the spring such that rotation of the support arm relative to the first arm causes the spring to move to the displaced position and the spring force is transferred to the support arm.

Abstract: Systems, methods, devices, and an apparatus for capping blood sample tubes after they are processed in an automated blood sample analysis processing system are provided. One aspect describes an automated blood sample tube capping assembly configured to automatically cap a plurality of sample tubes after they are processed in an automated blood sample analysis processing system.
