    • A method for determining the physical locations of a plurality of computers in a network is disclosed. The network includes a plurality of wall plates, each of the wall plates for coupling one of the computers to the network. The method and system comprises providing an additional information physical layer and logic in each of the wall plates. The method and system further comprises capturing and storing the system media access-controller (MAC) address of the connect computer in the additional logic of each of the plurality of wall plates and storing a physical address of the wall plate in the logic of each of the plurality of wall plates. The method and system also comprises providing a command from the network that will cause the system MAC address and the physical address of at least one of the plurality of computers to be provided to an application in the network. A system and method in accordance with the present invention adds a low cost physical layer and logic within an Ethernet wall plate associated with the computer on the network. The logic is designed to respond to a broadcast signal to a UDP (User Datagram Protocol) port. In so doing the physical location of the computer can be determined. In a preferred embodiment, a command is provided from the network that will cause the MAC address and the physical address of at least one of the plurality of computers to be provided to an inventory application in the network, thereby allowing a network administrator to remotely determine the physical location (room, floor, building, etc.) of any and all computers attached to the network.
    • 公开了一种用于确定网络中的多个计算机的物理位置的方法。 网络包括多个壁板,每个壁板用于将计算机中的一个耦合到网络。 该方法和系统包括在每个壁板中提供附加信息物理层和逻辑。 所述方法和系统还包括将连接计算机的系统媒体访问控制器(MAC)地址捕获并存储在多个壁板中的每一个的附加逻辑中,并将墙板的物理地址存储在每个壁板的逻辑中 多个壁板。 该方法和系统还包括从网络提供将使系统MAC地址和至少一个计算机的物理地址被提供给网络中的应用的命令。 根据本发明的系统和方法在与网络上的计算机相关联的以太网墙板内增加了低成本的物理层和逻辑。 该逻辑被设计为响应于UDP(用户数据报协议)端口的广播信号。 在这样做时,可以确定计算机的物理位置。 在优选实施例中,从网络提供将使多个计算机中的至少一个计算机的MAC地址和物理地址提供给网络中的清单应用的命令,从而允许网络管理员远程确定 连接到网络的任何和所有计算机的物理位置(房间,楼层,建筑物等)。

    • A method and system for providing diagonal scrolling on a touchpad of a device is disclosed. The method and system comprises determining if at least one finger is in contact with the touchpad, and entering a diagonal scroll mode if more than one finger is in contact with the touchpad. A system and method in accordance with the present invention allows the user to initiate a diagonal scroll at any location on a touchpad by using two fingers, thereby greatly enhancing the functions of the touchpad and allowing the user to manipulate computer programs from the touchpad much more efficiently and easily. The present invention supports diagonal scrolling on a touchpad and does not require a precise location for vertical or horizontal scrolling, since the entire touchpad area/surface can be used.
    • 公开了一种用于在设备的触摸板上提供对角滚动的方法和系统。 该方法和系统包括确定至少一个手指是否与触摸板接触,以及如果多于一个手指与触摸板接触,则进入对角线滚动模式。 根据本发明的系统和方法允许用户通过使用两个手指在触摸板上的任何位置处发起斜向滚动,从而大大增强了触摸板的功能,并允许用户从触摸板操纵更多的计算机程序 有效和容易地 本发明支持触摸板上的对角滚动,并且不需要垂直或水平滚动的精确位置,因为可以使用整个触摸板区域/表面。

    • Described is a system which includes at least one computer system connected to a main computer system via a data transmission network. The at least one computer system has a network connector for communicating data with the main computer. The network connector is supplied with auxiliary power and is operative to communicate with the main computer regardless of whether the at least one computer system is in a normal operating state. The main computer includes a program for detecting when the at least one computer system has been disconnected from the data transmission network. The program sends a first packet to the at least one computer system via the network. The at least one computer system is operative to receive the first packet and respond by sending a second packet to the main computer. The second packet includes data which specifically identifies the at least one computer system.
    • 描述了包括经由数据传输网络连接到主计算机系统的至少一个计算机系统的系统。 至少一个计算机系统具有用于与主计算机通信数据的网络连接器。 网络连接器具有辅助电源,并且可操作以与主计算机进行通信,而不管至少一个计算机系统是否处于正常工作状态。 主计算机包括用于检测至少一个计算机系统何时已经从数据传输网络断开的程序。 程序经由网络向第一个计算机系统发送第一个分组。 至少一个计算机系统可操作以接收第一分组,并通过向主计算机发送第二分组来进行响应。 第二分组包括专门识别至少一个计算机系统的数据。
