Abstract: Wire holders for overhead electrical wires (e.g. powerlines) are configured to be used with a temporary extension arm. Temporary extension arms and wire holders are used in adverse weather conditions which can be dangerous if a live wire escapes the wire holder. Proposed is a wire holder having a latch mounted to a first upright wherein the latch extends entirely between the first upright and a second upright when in a closed (first) position. When in the closed position, a wire can be held captive between the first upright, the second upright, the latch and a body of the wire holder. The latch is movable to an open (second) position, which allows the wire to be placed or removed from between the first upright and the second upright.

Abstract: The current document is directed to improved mechanical joints that each includes a compact, bypassable, single-spring or nested-spring wrap-spring clutch (“BSorNWS clutch”) and that can be incorporated into many different types of devices, appliances, and systems, including prosthetics. One application of a BSorNWS-clutch mechanical joint is as a mechanical knee within a prosthetic leg. A BSorNWS-clutch mechanical-knee component used in a prosthetic leg further includes upper-leg and lower-leg attachments that freely rotate when the prosthetic leg is unweighted but that are constrained, by weighting-induced activation of the BSorNWS-clutch, to rotate only in a lower-leg-extension direction. The BSorNWS-clutch mechanical-knee includes additional components that adjust the weighting force needed to bypass the BSorNWS clutch and to slightly relax the rotational constraint imposed by BSorNWS-clutch activation.

Abstract: The current document is directed to a two-way, by-passable, overrunning clutch incorporated within a mechanical prosthetic knee that provides functionality similar to a biological knee or incorporated in another articulated device, such as a robotic or orthotic articulated device or member. The currently disclosed two-way, by-passable, overrunning clutch allows for two-way free rotation when disabled, but, when enabled, prevents rotation in one direction while allowing free rotation in the other direction. In the mechanical prosthetic knee, the two-way, by-passable, overrunning clutch is enabled by application of a mechanical force and disabled by removal of the mechanical force.
