    • A deployable space panel structure for use in connection with space vehicles such as satellites and the like. The deployable space panel structure includes a first series of interconnected substantially flat panel members and a second series of interconnected substantially flat members. Pivotal connectors that allow substantially free rotational movement interconnect the edges of certain of the flat panel members of the first and second series of interconnected panel members and a deployment mechanism is provided that permit the first series of interconnected panel members to be in a separate plane from the second series of interconnected panel members. This permits the first and second series of interconnected panel members to have greater strength and rigidity than if they were both located in the same plane.
    • 用于与诸如卫星等的太空车辆相关联的可部署的空间面板结构。 可部署的空间面板结构包括第一系列互连的基本上平坦的面板构件和第二系列相互连接的基本上平坦的构件。 允许基本上自由的旋转运动的枢转连接器将第一和第二系列互连的面板构件的某些平板构件的边缘相互连接,并且提供了展开机构,其允许第一系列互连的面板构件处于与 第二系列互连面板成员。 这允许第一和第二系列互连的面板构件具有比它们都位于同一平面中的更大的强度和刚度。

    • Subscriber units operating within a communication system are selectively addressed and required to solve a "Puzzle" generated by a central device (controller) of a two-way communication system. The "Puzzle" comprises one or more digital words and an operand, which provides instructions to the subscriber unit as to how to generate an answer. The subscriber units cannot anticipate either the occurrence nor the content of a particular "Puzzle". All subscriber units (both authorized and unauthorized) must return an answer to the "Puzzle" or they may be denied access to the two-way communication system. Also, unauthorized subscriber units may be detected when the central device receives multiple answers to a "Puzzle".
    • 在通信系统中操作的订户单元被选择性地被寻址并且需要解决由双向通信系统的中央设备(控制器)产生的“拼图”。 “拼图”包括一个或多个数字字和操作数,其向订户单元提供关于如何产生答案的指令。 用户单元不能预测特定“拼图”的发生和内容。 所有订户单元(授权和未授权)都必须返回“谜题”的答案,否则可能会被拒绝访问双向通信系统。 此外,当中央设备接收到“难题”的多个答案时,可以检测到未经授权的订户单元。
