Abstract: A dynamics management system for a structure includes a line whose first end is coupled to a first location within a structure. A tension resistance device is coupled to a second location within the structure. The tension resistance device generates a first force when a tension force is applied thereto and generates a lesser second force when the tension force is not applied thereto. The second end of the line is coupled to the tension resistance device wherein the first force is applied to the line when it is in tension and the second force is applied to the line when it is not in tension. The line traverses at least one Z-shaped path within and in a plane of the structure. The line is coupled to the structure at each inflection point of the Z-shaped path(s) for supporting movement of the line there along.

Abstract: A unidirectional damping system includes a shaft and unidirectional damping modules. Each module is fixedly coupled to the shaft. Each module includes a fluid-filled variable-volume chamber and spring(s). The chamber has at least one port through which fluid flows based on changes in volume of the chamber wherein, when the shaft is adapted to have a unidirectional force applied thereto, the chamber decreases in volume. The spring(s) is coupled to the chamber for increasing volume of the chamber when the unidirectional force is not applied to the shaft. A fluid-filled spacer chamber is coupled between adjacent modules and is uncoupled from the shaft. The spacer chamber includes at least one venting port through which fluid flows based on pressure in the spacer chamber.

Abstract: A damping system includes a spool about which a tension line is wound. The line's first end is coupled to a first structure subject to forces causing unwanted movement thereof. A damper is coupled to a second structure not subject to the unwanted movement of the first structure. The damper is coupled to the spool for engagement with the spool to slow a rotational speed thereof when the spool rotates in a first direction. The damper is disengaged from the spool when the spool rotates in a second direction in opposition to the first direction. A device, coupled to the line's second end and to the second structure, applies a tension force to the line's second end. The tension force is exceeded when the first structure moves to place the line in tension, and is not exceeded when the first structure moves to place the line in compression.

Abstract: A bi-directional damping system generates damping forces in two opposing directions. A shaft has a plurality of bi-directional damping modules fixedly coupled thereto. Each module includes a fluid-filled variable-volume first chamber including at least one port through which fluid can flow based on changes in volume of the first chamber, and a fluid-filled variable-volume second chamber including at least one port through which fluid can flow based on changes in volume of the second chamber. The first chamber and second chamber are fluidically isolated from one another. A fluid-filled spacer chamber is coupled to adjacent ones of the modules. The spacer chamber includes at least one venting port through which fluid can flow based on pressure in the spacer chamber.
