摘要： One of a pair of concentric ring hoops overlaps the other and holds the perimeter edge of a drum head vibratile element in tension between the mating overlapping faces of the hoops. The hoops are held together by a tensioning bolt threadable into a bracket connected to a lower hoop which has another skin stretched between a stepped inner annular groove on its inner face edge. A drum shell made of a composite of rigid foam interior spaced apart by a pair of epoxy impregnated carbon fibresheets is held by the lower second drum skin into enclosing engagement on its upper perimeter edge with an inner stop flange and vertical wall face of the inner hoop ring of the drum head vibratile skin assembly.

摘要： A power-operated system for actuating the rear doors or liftgates of motor vehicles includes a strut assembly having two struts, each strut mounted on one side of the door between the door and the vehicle's door frame. One end of each strut is connected to a powered rotating arm. To open the door, the rotating arms change the angular orientation of the struts such that they have a substantial mechanical advantage. In this position, the force provided by the struts overcomes the weight bias of the door, thus opening the door. To close the door, the rotating arms change the angular orientation of the struts such that the struts have a decreased mechanical advantage, reducing the force provided by the struts, and therefore causing the door to fall closed under its own weight bias. A control system for controlling the power-operated system is also disclosed.

摘要翻译： 用于致动机动车辆的后门或升降门的动力操作系统包括具有两个支柱的支柱组件，每个支柱安装在门与门的车门框架之间的门的一侧。 每个支柱的一端连接到动力旋转臂。 为了打开门，旋转臂改变支柱的角度定向，使得它们具有实质的机械优点。 在这个位置上，由支柱提供的力克服了门的重量偏差，从而打开门。 为了关闭门，旋转臂改变支柱的角度定向，使得支柱具有降低的机械优点，减小由支柱提供的力，并且因此导致门在其自身重量偏压下下降。 还公开了一种用于控制动力操作系统的控制系统。

摘要： A drum includes a rigid, hollow body disposed about an axis and having first and second opposing opened ends of generally circular form. The body has an inner surface and an outer surface with the outer surface being of convoluted form defined by a plurality of channels formed in the body. The channels extend in a direction of the axis. A drum head membrane covers each of the first and second ends. A ring is mounted on each of the first and second ends so as to secure each drum head membrane to the body. Each ring includes a tensioning member receiving structure. A plurality of tensioning members are provided with a tensioning member being received in an associated channel and a first end of each tensioning member being received by the tensioning member receiving structure of each ring. The tensioning members are constructed and arranged to be moved with respect to the body to adjust tension of the drum head membranes.
