    • An environment for remote monitoring of a device, such as a child's computer, from a television or other monitor device. The monitored device has a security layer, which may be implemented in hardware, software, or a combination of the two, where the security layer inspects some or all accessed network data or network access activities, including real-time content such as chat rooms and the like. While the monitored device is used to access network data, alerts are displayed on the remote monitoring device to allow an adult or other responsible entity to keep track of material. Thus, for example, an adult may watch television, confident that an alert will be displayed in a corner of the television screen if necessary to alert the adult to any problems. For serious alerts, the security layer may automatically block or shutdown offending network application programs.
    • 用于从电视机或其他监视器装置远程监控诸如儿童电脑的设备的环境。 所监视的设备具有安全层,其可以以硬件,软件或两者的组合来实现,其中安全层检查一些或所有访问的网络数据或网络访问活动,包括实时内容,例如聊天室和 类似。 当被监控设备用于访问网络数据时,警报将显示在远程监控设备上,以允许成年人或其他负责实体跟踪材料。 因此,例如,成年人可以观看电视,相信如果需要警告成人有任何问题,则警报将显示在电视屏幕的角落。 对于严重警报,安全层可能会自动阻止或关闭违规网络应用程序。

    • A method of monitoring logical connections in a computer network is described. All packets exchanged via the network are intercepted and analyzed. Upon receipt of a packet, a connection management engine determines whether packet is part of an existing logical connection. If it is not, a new record is created and stored in a connection record database. Otherwise, the existing record for the logical connection in the connection record database is updated.Also described is a method of monitoring file transfers in a computer network. File transfers are monitored using an file transfer record database, which allows each packet of the file transfer to be placed in proper context. Upon interception of a packet, an application management engine (AME) first determines whether the packet is part of a file transfer. If it is not, the AME ignores the packet. On the other hand, if the packet is part of a file transfer, then the AME determines whether if the packet is part of a new file transfer or a one of a multiplicity of existing file transfers. The AME creates a new record if the packet is the start of a new file transfer. If the packet is part of an existing file transfer, then the AME searches the file transfer record database to locate the record for the file transfer, which the packet is part of. Once located, the record is updated.Apparatus for monitoring file transfers and logical connections are also described.
    • 描述了监视计算机网络中的逻辑连接的方法。 通过网络交换的所有数据包被截取和分析。 在接收到分组时,连接管理引擎确定分组是否是现有逻辑连接的一部分。 如果不存在,则创建新记录并存储在连接记录数据库中。 否则,更新连接记录数据库中逻辑连接的现有记录。 还描述了一种监视计算机网络中的文件传输的方法。 使用文件传输记录数据库监视文件传输,这样可以将文件传输的每个数据包放置在适当的上下文中。 在截取数据包时,应用程序管理引擎(AME)首先确定数据包是否是文件传输的一部分。 如果不是,AME忽略数据包。 另一方面,如果分组是文件传输的一部分,则AME确定分组是否是新文件传输的一部分或多个现有文件传输中的一个。 如果数据包是新的文件传输的开始,AME将创建一个新的记录。 如果数据包是现有文件传输的一部分,则AME将搜索文件传输记录数据库,以查找文件传输的记录,该数据包是其中的一部分。 一旦找到,记录被更新。 还描述了用于监视文件传输和逻辑连接的装置。

    • A field effect device having a floating gate which can be charged or discharged electrically is disclosed. A pair of spaced apart regions in a substrate define a channel above which a floating gate is disposed and insulated from the channel. The regions have a conductivity type opposite to the substrate. A second gate is disposed above and insulated from the floating gate. The floating gate may be charged electrically by producing an avalanche breakdown at the junction formed by one of the spaced apart regions and the substrate causing the passage of electrons through the insulation onto the floating gate. The floating gate may be discharged by the application of a voltage to the second gate relative to the spaced apart regions and substrate causing the passage of electrons from the floating gate through the insulation onto the second gate.
    • 公开了一种具有浮动栅极的场效应器件,其可以被电荷充放电。 衬底中的一对间隔开的区域限定了一个通道,在该通道上方,浮动栅极被设置并与通道绝缘。 这些区域具有与衬底相反的导电类型。 第二栅极设置在浮动栅极的上方并与其隔离。 浮动栅极可以通过在由一个间隔开的区域和衬底形成的接合处产生雪崩击穿而导致电子通过绝缘体进入浮动栅极而被电荷充电。 可以通过相对于间隔开的区域和衬底向第二栅极施加电压而使浮置栅极放电,导致电子从浮栅通过绝缘到第二栅极。
