    • The invention relates to a ground-based wireless cellular communication system (1a) for providing in-flight broadband mobile communication services, comprising: at least one ground-based base station (2) adapted for generating at least one cell (C1, C2) defining a solid angle of the space surrounding the base station (2), the ground- based base station (2) further comprising at least one antenna array (5a, 5a) using two-dimensional-beamforming for generating at least one beam (6a-c, 7a-c) for serving at least one airplane (8a-c, 8c-e) in the space covered by the at least one cell (C1, C2) using spatial-division multiple access, SDMA. The invention also relates to an airplane equipment for providing in-flight broadband mobile communication services, comprising: at least one antenna for exchange of user data with the ground-based wireless cellular communication system (1a), a transceiver unit connected to the at least one antenna for handling the air-to-ground and ground-to-air communication with the ground-based wireless cellular communication system (1a), and an inside-airplane communication system for distributing the user data to and from terminals within the airplane.
    • 本发明涉及一种用于提供飞行中宽带移动通信业务的地面无线蜂窝通信系统(1a),包括:至少一个基于地面的基站(2),适用于生成至少一个小区(C1,C2) 定义基站(2)周围的空间的立体角,所述地基基站(2)还包括使用二维波束形成的至少一个天线阵列(5a,5a),用于产生至少一个波束(6a -c,7a-c),用于使用空分多址(SDMA)在由至少一个小区(C1,C2)覆盖的空间中服务至少一个飞机(8a-c,8c-e)。 本发明还涉及一种用于提供飞行中宽带移动通信服务的飞机设备,包括:用于与地面无线蜂窝通信系统(1a)交换用户数据的至少一个天线,至少连接到该无线蜂窝通信系统 用于处理与地面无线蜂窝通信系统(1a)的空对地和地对空通信的一个天线,以及用于将用户数据分发到飞机内的终端的飞机内通信系统。

    • A rotary punch includes an upper die plate, a lower die plate, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway. The lower die plate is connected to the support frame for movement in a linear horizontal direction only. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods attached to the upper die plate that extend down through bushings provided in the lower die plate. In operation, the lower die plate horizontally follows the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper plate moves towards and away from the lower plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.
    • 旋转冲头包括上模板,下模板和具有驱动组件的支撑框架,该驱动组件沿着大致圆形的路径水平和垂直地移动上模板。 下模板连接到支撑框架,仅在线性水平方向上运动。 上模板通过一个或多个垂直杆垂直地可滑动地连接到下模板,该垂直杆附接到上模板,该垂直杆向下延伸穿过设置在下模板中的衬套。 在操作中,当下模板沿其圆形路径移动时,下模板水平地跟随上模板。 同时,上板向下移动并远离下板。 这保持了模板之间的基本上恒定的对准,用于对通过其间的材料的移动的网状物进行周期性的加工操作。
