Abstract: Technologies are described for aquatic resistance training. An aquatic resistance line may be deployed across the surface of a swimming pool. An aquatic resistance device may be deployed to ride along the resistance line when pulled by a swimmer. The aquatic resistance device comprises offset compression tensioners, each with a wedge-like geometry and a channel for the resistance line. The housing of the aquatic resistance device positions adjacent pairs of the offset compression tensioners into alternating orientation to one another.

Abstract: The disclosure relates to a system and method for replacing an existing door while using the existing door frame structure. The system includes a mounting tool designed to locate a position of a door hinge on an existing door, and indicate a corresponding position for the door hinge on the replacement door without requiring substantial measurements or formation of hinge mortises. An edge mounting strip may be secured to the replacement door to complete the assembly and provide a flush surface with the door hinges along the end of the replacement door.

Abstract: A counterbalance system for an exoskeleton is provided, including a first hip joint to displace an external load experienced by a user above a waist of the user, the first hip joint provides for three degrees of freedom of movement, a tool interface located above the first hip joint to direct load displacement through the first hip joint, and a counterbalance arm having a first end and a second end, the counterbalance arm is secured to the tool interface at the first end, the second end of the counterbalance arm is moveable in an arcuate rotational path ranging from in front of the tool interface to behind the tool interface. Another system and method are also provided.

Abstract: A latch for coupling a first object to a second object is disclosed comprises a primary block coupled to the first object. A locking cam is rotatably coupled to the primary block. A cam track having a sloped surface is in the locking cam. A locking stem slideably engages the primary block and traverses the locking cam. A cam pin is coupled to the locking stem. The cam pin slidably engages the sloped surface for displacing the locking stem between an extended position and a retracted position. A stem head is coupled to the cam pin. A secondary block is coupled to the second object. A cam channel is in the secondary block for receiving the locking stem. A head receiver is in the secondary block for engaging the stem head. The extended position defines an unlocked position and the retracted position defines a locked position.

Abstract: An exoskeleton system is disclosed including a hip joint to provide anatomically emulating three degrees of freedom of movement of the hip joint at a hip location of a user, a knee joint to provide anatomically emulating forward and backward movement of the knee joint at a knee location of the user, an ankle joint to provide anatomically emulating forward and backward movement of the ankle joint at an ankle location of the user, a knee rocker arm as part of the knee joint to transfer a load to a ground surface when the knee rocker arm is in contact with the ground surface as manually powered by the user, and a ground rocker arm as part of the ankle joint to transfer the load to a ground surface when the ground rocker arm is in contact with the ground surface as manually powered by the user.

Abstract: A magnetic gate latch comprises magnetic materials and a latching mechanism attracted into a keeper when the gate latch is closed by a first magnetic force and retained in a unlatched position by a second magnetic force. For example, the latching mechanism comprises a pin without a spring or other biasing mechanism biasing the spring in a direction opposite of a magnet in the keeper assembly. In one example, the pin comprises a magnet on an end of the pin opposite from the keeper assembly, which is attracted toward a ferromagnetic material when the pin is retracted into the housing.

Abstract: The invention is directed to a gas powered self-contained winch comprising an external casing including a first side wall, a second side wall, a top wall, a bottom wall and a stabilizing bar. The invention includes a combustion engine; a transmission assembly, a gear assembly and a clutch assembly that connect to a spool capable of winding and unwinding a cable wire. A hand controller can communicate with the clutch assembly through a cable wire sufficient to control the winding and unwinding of the cable.
