    摘要： An exercise device is provided including a foot link having a rearward end and a forward end. An adjustable stride mechanism is provided. The adjustable stride mechanism includes a primary gear and a secondary gear. The primary gear is sized larger relative to the secondary gear. A primary crank connects the primary gear and the secondary gear. A timing belt connects the primary gear to the secondary gear. The primary crank and the timing belt enable the secondary gear to rotate around the primary gear. A secondary crank is pivotally attached to the secondary gear and to a foot link. The secondary crank creates an ellipse-shaped path for the foot link as the secondary gear rotates around the primary gear. Thus, the foot link motion combines an at least a dual ellipse motion. An automatic adjusting mechanism can be provided to adjust the adjustable stride mechanism.

    摘要： A self-actuated structure, such as an antenna structure, is provided that can be stowed in a compact manner and can be deployed in a self-actuated fashion. The self-actuated structure includes a flexible skin, a boom extending thereacross and rings about which the flexible skin can be folded such that a payload volume is defined therewithin. The self-actuated structure also has a plurality of ribs extending parallel to the boom that cooperate with the flexible skin to define a number of channels extending between the boom and an edge of the flexible skin. The structure also includes a plurality of self-deploying stiffeners disposed within respective channels. In this regard, the stiffeners can have an unbiased relaxed shape, such as a “U” shape, in the absence of external forces and a biased shape, such as a flat shape, upon the application of external bias forces. As such, the application of external bias forces, such as by cables interconnecting the rings and an outermost rib, can cause the stiffeners to assume a biased shape, i.e., a flat shape, by moving the structure into the first position, typically a stowed position, while the removal of external bias forces allows the stiffeners to assume the unbiased relaxed shape, which moves the structure into the second position, typically a deployed position.

    摘要翻译： 提供了诸如天线结构的自动致动结构，其可以以紧凑的方式收纳并且可以以自动方式展开。 自动致动结构包括柔性皮肤，在其上延伸的悬臂和围绕柔性皮肤折叠的环，使得在其中限定有效载荷体积。 自动致动结构还具有平行于吊杆延伸的多个肋，其与柔性皮肤协作以限定在悬臂与柔性皮肤的边缘之间延伸的多个通道。 该结构还包括设置在各个通道内的多个自展开加强件。 在这方面，在施加外部偏压力的情况下，加强件可以在没有外力和偏置形状（例如平坦形状）的情况下具有无偏的松弛形状，例如“U”形。 因此，外部偏置力的应用，例如通过将环和最外侧肋相互连接的电缆，可以通过将结构移动到第一位置（通常是收起的）而使得加强件呈现偏置的形状，即平坦的形状 位置，而外部偏置力的移除允许加强件呈现无偏的松弛形状，其将结构移动到第二位置，通常是展开位置。
