    • A DNS engine monitors domain name system (DNS) network activity occurring between a user computer and a remote computer server. The engine collects DNS traffic information during a specified time window at the user computer using the monitored DNS network activity. The engine generates a local DNS reputation for the user computer and stores the local DNS reputation on the user computer. When a triggering event is received at the user computer the engine determines that the triggering event is abnormal in comparison to the stored local DNS reputation. An alert is issued to a software product on the user computer. The engine takes an action using a software product upon the alert. The reputation may be a frequency distribution for each accessed domain name and IP address. A triggering event may be an abnormal access to a domain name or IP address, or a mismatch between DNS queries and DNS responses of the user computer.
    • DNS引擎监视在用户计算机和远程计算机服务器之间发生的域名系统(DNS)网络活动。 引擎在用户计算机的指定时间窗口内使用监控的DNS网络活动收集DNS流量信息。 引擎为用户计算机生成本地DNS信誉,并在用户计算机上存储本地DNS信誉。 当在用户计算机上接收到触发事件时,与存储的本地DNS信誉相比,引擎确定触发事件是异常的。 向用户计算机上的软件产品发出警报。 引擎在警报时使用软件产品进行操作。 声誉可能是每个访问的域名和IP地址的频率分布。 触发事件可能是对域名或IP地址的异常访问,或DNS查询与用户计算机的DNS响应之间的不匹配。

    • A retractor with multiple blades for use in surgery. The retractor may comprise first and second elongated portions which are pivotally connected to each other. A first blade may be connected to the first elongated portion and a second blade may be connected to the second elongated portion. The retractor may also comprise a sliding bar having a third blade. The sliding bar may be associated with the first and second elongated portions such that movement of the elongated portions relative to each other may result in movement of the sliding bar and, consequently, movement of the third blade relative to the first and second blades. In one embodiment, the retractor may comprise a tension limiting device so that the third blade may remain relatively stationary as the first and second blades are moved. The retractor may also comprise a fourth blade operatively connected to the first and second elongated portions. The fourth blade may be moved independently of the other blades or may move with the other blades. Also disclosed is a method of retracting tissue.
    • 具有多个刀片的牵开器用于手术。 牵开器可以包括彼此枢转地连接的第一和第二细长部分。 第一叶片可以连接到第一细长部分,并且第二叶片可以连接到第二细长部分。 牵开器还可以包括具有第三叶片的滑动杆。 滑动杆可以与第一和第二细长部分相关联,使得细长部分相对于彼此的移动可导致滑动杆的移动,并且因此导致第三叶片相对于第一和第二叶片的运动。 在一个实施例中,牵开器可以包括张力限制装置,使得当第一和第二叶片移动时,第三叶片可保持相对静止。 牵开器还可以包括可操作地连接到第一和第二细长部分的第四叶片。 第四刀片可以独立于其他刀片移动,或者可以与其他刀片一起移动。 还公开了一种缩回组织的方法。
