    • A system and method for a self-actuating, mechanically-biased container restraint. The system requires no computer-aided control or timing, nor is any external power source needed, other than the force exerted as a container is inserted into the restraint. The system relies upon an assembly including mechanically-biased pivoting levers, each of which has a horizontal element and a vertical element. All actuation occurs as the base of an inserted container comes into contact with the upper surface of the horizontal elements of multiple pivoted levers positioned at the base of a channel adapted to serve as a guide for the inserted tube. The levers are biased in this elevated position by mechanical means, such as a spring. As the inserted tube presses the horizontal members downward, the top portions of the vertical members are pivoted inward toward the container's exterior. Friction pads situated upon the interior surface of each vertical element are brought into contact with the exterior of the container, thereby gripping it. This gripping action holds the container with sufficient friction to permit the removal or attachment of a screw cap. Further embodiments of the invention include a mechanically biased platform supporting the channel and the pivoting levers. This base is biased and positioned to permit the channel and the pivoting lever assembly to be translated downward against the force biasing the platform and translate through the body of the container restraint. This further advancement of container, the channel and the lever assembly cause the pivoting levers to assume fully engaged gripping positions, and brings the vertical elements of the levers (and flexible friction pads upon them) into full upright positions. In this position the friction pads apply a maximum static friction force to the exterior of the container.

    • A system and method for gripping, torqueing and releasing an element so as to cap and/or decap a container, such as those typically utilized to house specimens in laboratory environments. The system is driven by a single bi-directional motor linked to a coupler assembly via a rotating threaded shaft. The coupler assembly is configured to engage with an element, such as a cap or container, via mechanically-biased splines that are actuated without any complex linkages, or operative connection to the motor or other powered components. The system employs an ejector nut and an ejector, both of which are concentrically positioned about the threaded shaft. The ejector nut translates along the shaft as a function of the shaft's rotation, so as to permit the retraction of the ejector when an element is engaged in the coupler assembly or cause the ejector to extend into the coupler assembly to disengage the element. The direction and rotation of the motor is controlled by a system coupled to sensors positioned within the system. Such control system may include one or more processors, component interfaces, and data storage/memory. The sensors may include multiple optical, magnetic or mechanical means for monitoring one or more of the positions of the ejector nut and ejector along the threaded shaft, and/or the rotational position of the coupler assembly.
