    • A system (126-129) detects transmission of potentially malicious packets. The system (126-129) receives packets and generates hash values corresponding to each of the packets. The system (126-129) may then compare the generated hash values to hash values corresponding to prior packets. The system (126-129) determines that one of the packets is a potentially malicious packet when the generated hash value corresponding to the one packet matches one of the hash values corresponding to one of the prior packets and the one prior packet was received within a predetermined amount of time of the one packet. The system (126-129) may also facilitate the tracing of the path taken by a potentially malicious packet. In this case, the system (126-129) may receive a message that identifies a potentially malicious packet, generate hash values from the potentially malicious packet, and determine whether one or more of the generated hash values match hash values corresponding to previously-received packets. The system (126-129) may then identify the potentially malicious packet as one of the previously-received packets when one or more of the generated hash values match the hash value corresponding to the one previously-received packet.
    • 系统(126-129)检测潜在恶意数据包的传输。 系统(126-129)接收分组并产生与每个分组对应的散列值。 然后,系统(126-129)可以将生成的散列值与对应于先前分组的散列值进行比较。 当对应于一个分组的生成的散列值与对应于先前分组之一的哈希值中的一个匹配,并且在一个分组内接收到一个先前分组时,系统(126-129)确定分组中的一个是潜在的恶意分组 一个分组的预定时间量。 系统(126-129)还可以便利跟踪潜在的恶意数据包所采取的路径。 在这种情况下,系统(126-129)可以接收标识潜在恶意数据包的消息,从潜在的恶意数据包生成散列值,并确定所生成的散列值中的一个或多个是否与先前接收到的散列值相匹配 数据包 然后当一个或多个所生成的散列值与对应于先前接收的一个分组的散列值相匹配时,系统(126-129)可以将潜在的恶意分组识别为先前接收的分组之一。

    • A non-powered roller conveyor for conveying parts along a conveyor path includes a downwardly sloped conveyor support frame with a plurality of rollers rotatably mounted along the frame. The rollers comprise a length of prefabricated roller top conveyor chain mounted along a top surface of the conveyor frame. The conveyor chain includes a plurality of links connected together by pivotal connectors that permit sideways articulation of the links with respect to each other. Transverse rows of rollers are rotatably mounted on the links to permit products to roll along the conveyor. The rollers are easily replaceable when necessary. The conveyor follows a downwardly extending spiral path comprising a series of inclined straight sections interconnected by inclined bend sections. Both the straight and bend sections are inclined so that parts roll along the conveyor path under the influence of gravity.
    • 用于沿着传送路径输送部件的非动力辊式输送机包括一个向下倾斜的传送器支撑框架,其具有沿框架可旋转地安装的多个辊。 辊子包括沿输送机框架的顶表面安装的长度的预制的辊顶输送链。 传送链包括通过枢转连接器连接在一起的多个链节,其允许链节相对于彼此侧向铰接。 滚筒的横列可旋转地安装在连杆上以允许产品沿输送机滚动。 滚筒在必要时可轻松更换。 输送机沿着一个向下延伸的螺旋路径,包括一系列通过倾斜弯曲部分相互连接的倾斜的直线段。 直线部分和弯曲部分都是倾斜的,使得部件在重力的作用下沿传送路径滚动。
