Abstract: A rotatable and removable wrist connection for a prosthetic hand. A prosthesis coupling includes first and second ball race sections that may be moved together or apart to constrain ball bearings to an inner zone or an outer zone to allow the prosthesis coupling to be secured to or removed from a socket coupling. A socket coupling includes a socket body for receiving a wrist coupling having a rotary connector core extending from the socket body and compliantly mounted to the socket body.

Abstract: The invention relates to an automated hand, such as a prosthetic hand. In one form, the automated hand may be fluid compatible. In one form, the automated hand may comprise features to reduce the risk of harm to motors and/or other sensitive components of the hand when subject to an impact. In one form, the hand may comprise a wrist joint configured to allow the hand to curl and flex and/or to rotate. In one form, one or more digits of the hand may be individually controlled. In one form the hand may include a thumb rotation locking mechanism. In one form the hand may be provided with removable grip plates. In one form, the hand may be configured for use as a training hand.

Abstract: The disclosed apparatus, systems and methods relate to a safety chain tool for use with gooseneck trailers. Various embodiments of the tool allow the user to remotely affix the safety chains of a gooseneck trailer, and are configured so as to be left in the bed of the truck during transport so as to allow for easy removal of the chains. In certain implementations, the tool comprises an elongate shaft with a handle at one end and a coupling mechanism at the other, wherein the coupling mechanism is fixedly attached to a chain and a clasp. In certain embodiments, the shaft contains a operational mechanism configured to actuate the clasp. In certain embodiments, this actuation is achieved by extending the ends of the shaft relative to one another.

Abstract: The invention relates to a gripping device, such as an automated hand, comprising a plurality of metacarpal members, each metacarpal member having a first end attached to a support frame via a universal joint and having a second end attached to a gripping member, wherein the metacarpal members are able to pivot upwardly, downwardly and laterally. Where adjacent metacarpal members together form a palm of the hand, the ability of the metacarpal members to move up, down and laterally helps the palm to grip an object and also helps the palm to withstand at least some forces from above, below and from the side.
