| 20080197548 | Self-retracting extension limiting device - A self-retracting extension limiting device. It is designed to be attached between a first object and a second object, where the distance between the first and second objects is variable.

| 20140015176 | RATE-RESPONSIVE, STRETCHABLE DEVICES - Rate-dependent, elastically-deformable devices according to various embodiments can be stretched and recovered at low elongation rates. Yet they become stiff and resistive to stretching at high elongation rates. In one embodiment, a rate-dependent, elastically-deformable device includes an elastically-deformable confinement member; one or more filaments placed inside the elastically-deformable confinement member; and a fluid that substantially fills the remaining volume inside the elastically-deformable confinement member. The resistance force to extension of the device is designed to increase as the extension rate of the device increases. At low elongation rates the filaments can readily slide past each other. At high elongation rates, the fluid transforms to a less flowable material that greatly increases the force and energy required for elongation; or transforms to a non-flowable material that resists elongation. The devices thus can be stretched and recovered at low elongation rates, but become extremely stiff and resistive to stretching at high elongation rates. | 01-16-2014 |

The cable forms two segments each of which couples the spring to the load. The two segments of the cable pass over a pulley. A sensor coupled to the pulley senses rotation of the pulley allowing cable breakage to be detected by the anomalous rotation of the pulley. | 12-31-2009 |
