    • A fluid system, a control valve therefor, and a method of its operation are provided. The fluid system includes a piping run, and a control valve which includes: a housing having an inlet connected to the piping run, an outlet connected to the piping run, and a pressure port; and a elastomeric tube disposed inside the housing, the tube having a flow passage extending therethrough which is in fluid communication with the inlet and outlet. An outer surface of the tube and the housing cooperatively define a pressure chamber which is in fluid communication solely with the pressure port, A source of controlled fluid pressure is connected to the pressure port to modulate flow in the tube. The tube is sized and the valve is operated so as to provide accurate flow rate control.
    • 提供一种流体系统,其控制阀及其操作方法。 流体系统包括管道运行和控制阀,其包括:壳体,其具有连接到管道的入口,连接到管道的出口和压力端口; 以及设置在所述壳体内部的弹性体管,所述管具有延伸穿过其中的流动通道,其与所述入口和出口流体连通。 管的外表面和壳体协同地限定了压力室,其仅与压力端口流体连通。受控流体压力源连接到压力端口以调节管中的流动。 管的尺寸大小并且阀被操作以提供精确的流量控制。

    • A match and destroy (MaDe) technique for filtering spam mail assigns at least two email addresses per user when the user first registers for an email account or when the MaDe software is installed on the server. The first email address is designated as the “True address,” and the user is made aware of only this address. The second email address is designated as the “Trap address,” and the user is not made aware of this address. Spammers send spam mail to all available email addresses as a spammer is unable to differentiate a True address from a Trap address. A MaDe filter is provided that detects when the same email is received in both the True and the Trap(s) inboxes. When this duplicate receipt occurs, the filter informs the resident spam filters that the email is a spam candidate.
    • 当用户首次注册电子邮件帐户或MaDe软件安装在服务器上时,用于过滤垃圾邮件的匹配和销毁(MaDe)技术至少为每个用户分配两个电子邮件地址。 第一个电子邮件地址被指定为“真实地址”,用户只知道这个地址。 第二个电子邮件地址被指定为“陷阱地址”,用户不知道该地址。 垃圾邮件发送者将垃圾邮件发送到所有可用的电子邮件地址,因为垃圾邮件发送者无法区分真实地址和陷阱地址。 提供了一个MaDe过滤器,用于检测在True和Trap(收件箱)中收到同一封电子邮件的时间。 当发生这种重复的收据时,过滤器通知居民的垃圾邮件过滤器,该邮件是垃圾邮件候选者。
