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.

Abstract: A tool (1) for loosening or removing a set (2) of barbs (3) from barbed wire (4) is disclosed. The barbed wire has at least one strand (7) of wire and a plurality of spaced apart sets of barbs wound around the wire. The barbs extend in substantially opposite directions from a wire helix (6) wound around the wire. The tool has first and second portions (11) each engageable with the wire and having an opposed levering element (8) that is radially offset from the wire for applying leverage to the helix. Rotation of the portions in a first direction abuts each of the levering elements against a corresponding one of the pair of barbs to unwind or unfurl the helix.

Abstract: The present invention discloses a fence system, which is composed of a plurality of assembly units that are detachably connected in sequence. Each assembly unit includes a base, a fixed assembly, a winding apparatus, an outer bar body and a net body. The winding apparatus is fixed on the top of the base, located in the outer bar body and used to drive the outer bar body to rotate around the base, so that the net body is wound on the outer side of the outer bar body. The fixed assembly is retracted into the base or unfolded and fixed on the bottom of the base. The present invention realizes convenience in disassembling and assembling, realizes the automatic winding of the net body, thereby facilitating the transfer and reuse of the assembly units; and enhances the stability of the assembly units and the overall structure and achieving good practicability.

Abstract: A quick coupler provides a way to securely lock implements to the coupler utilizing a design which receives hooks at connection locations and then directs pins into pockets at a rear of the implement. Instead of directing the pins along a pocket axis (as is done in the prior art), the pins are directed at an angle relative to the pocket axis thereby securely connecting the coupler to the implement. In fact some embodiments can have a pin extension system spaced from a wedge plate surface defining the pocket of the implement.

Abstract: An apparatus with two anchors including a housing, a movable element, and a rotary element is provided. The housing includes a first expansion unit, a second expansion unit, and a linkage. First alignment structures are disposed in the movable element and anti-rotation structures are disposed in the linkage. When the movable element and the rotary element enter the housing from two ends and are coupled along an axis, the movable element and the rotary element can approach each other to expand the first expansion unit and the second expansion unit to form two anchors. The apparatus with two anchors secures a sensor in a variety of environments such as walls or machines. When the apparatus with two anchors fixes a sensor in a hole of a stamping machine, the impact force does not cause stress concentration on the sensor so as to improve the reliability of the sensor.
