    • A multi-application transparent platform intercepts an incoming application file communicated from a source across a first TCP connection by terminating the first TCP connection on the multi-application transparent platform and supplying the application file to an application program. The application file is received onto the platform in the form of multiple incoming Ethernet frames. The application layer program analyzes the application file and identifies characteristics of the application file, such as virus content, that are not apparent in the individual Ethernet frames that carried the application file over the first TCP connection. The platform resends the application file over a second TCP connection in outgoing frames having the same IP addresses and Ethernet MAC addresses as the incoming frames. The platform can be inserted into a running network without reconfiguring devices on the network.
    • 多应用透明平台通过终止多应用透明平台上的第一TCP连接并将应用文件提供给应用程序来拦截通过第一TCP连接从源传送的传入应用文件。 应用文件以多个传入的以太网帧的形式被接收到平台上。 应用层程序分析应用程序文件,并识别通过第一个TCP连接承载应用程序文件的各个以太网帧中不明显的应用程序文件(如病毒内容)的特征。 该平台通过第二个TCP连接在具有与传入帧相同的IP地址和以太网MAC地址的输出帧中重新发送应用程序文件。 该平台可以插入到正在运行的网络中,而无需重新配置网络上的设备。

    • A steerable toboggan for sledding on snow is disclosed which includes a support having a bottom gliding surface which slides directly on the snow, and a pair of runner arms carrying guide ribs which extend forwardly beyond the gliding surface. Each of the guide ribs includes a curved portion which is vertically movable relative to the other between a raised position, with the curved portion raised above the snow, and a lowered position where the curved portion of the guide rib is brought against the snow. The toboggan is steered by selectively lowering the curved portion of one of the guide ribs onto the snow as the toboggan moves. The bulk of the user's weight is supported by the underlying snow, enabling the support to be formed from thinner less expensive materials, without requiring complex manufacturing processes.
    • 公开了一种用于在雪地上雪橇的可操纵的雪橇,其包括具有在雪上直接滑动的底部滑翔表面的支撑件,以及一对承载引导肋的向前延伸到滑行表面之上的导向肋。 每个引导肋包括弯曲部分,该弯曲部分可相对于彼此垂直移动,该凸起部分在凸起位置与弯曲部分在雪上方升高之间,以及下降位置,其中引导肋的弯曲部分抵靠着雪。 通过选择性地将滑板中的一个的弯曲部分降低到雪上,从而使雪橇滑行转向。 用户体重的大部分由底层的雪支撑,使得支撑由更薄的更便宜的材料形成,而不需要复杂的制造工艺。
