    • Objects can be tracked within a building using a radio device associated with each object to be tracked and an array of transmitting beacons. Each of the beacons transmits identification data. The received identification data from the object to be tracked is sent to a server which determines the location of the object. The identification data may be sent from the object to the server using a data communications network such as a local area network. The beacons may have a variable power output allowing the receipt or non-receipt of the signal from the beacon to be used to assist in locating the object. The beacons may be associated with an existing wireless communication mechanism, such as Bluetooth.
    • 可以使用与要跟踪的每个对象相关联的无线电设备和传输信标阵列在建筑物内跟踪对象。 每个信标传送识别数据。 从被跟踪对象的接收到的识别数据被发送到确定对象的位置的服务器。 识别数据可以使用诸如局域网的数据通信网络从对象发送到服务器。 信标可以具有可变功率输出,允许来自信标的信号的接收或不接收被用于帮助定位对象。 信标可以与诸如蓝牙的现有无线通信机制相关联。

    • A client computer system (10) is adapted to connect to a server (16) across a network (20). The client system includes memory (25 or a storage medium) into which an operating system is loadable. The client includes a network card (12) having a PROM (14) adapted to download a bootstrap program (17) from the server. The bootstrap program (17) is in turn adapted to load an operating system image (18) over the network from the server into a location in the memory. The client then boots from the operating system image in memory, with the client system being adapted to subsequently modify the operating system image in memory, without reloading the image over the network, and re-boot the client system.
    • 客户端计算机系统(10)适于通过网络(20)连接到服务器(16)。 客户端系统包括操作系统可加载的存储器(25或存储介质)。 客户端包括具有适于从服务器下载引导程序(17)的PROM(14)的网卡(12)。 引导程序(17)又适于将来自服务器的网络上的操作系统映像(18)加载到存储器中的位置。 然后,客户端从内存中的操作系统映像引导,客户端系统适应随后在内存中修改操作系统映像,而无需通过网络重新加载映像,并重新启动客户端系统。
