    • A method and system is provided that in a fully automated manner facilitates comparison shopping retail products online. An exemplary method according to the invention is a method for automated comparative shopping. A product for sale by a first merchant that is displayed to a user on a web page is first identified and first records relating to the product are extracted from the web site, including the price of the product and the name of the first merchant. Second records from a database system are retrieved, including the price of the product and the name of the one or more second merchants selling the product, and are formatted into one or more merchant listings, each merchant listing including at least the name of the merchant and the price of the product. The merchant listings are then provided for display to the user.
    • 提供了一种以全自动化方式在线购物零售产品的比较方法和系统。 根据本发明的示例性方法是用于自动比较购物的方法。 首先确定由网页上的用户显示的由第一商家出售的产品,并从网站中提取与商品相关的第一记录,包括商品的价格和第一商家的名称。 检索来自数据库系统的第二记录,包括产品的价格和销售产品的一个或多个第二商家的名称,并被格式化成一个或多个商家列表,每个商家列表至少包括商家名称 和产品的价格。 然后提供商家列表以供用户显示。

    • A method and apparatus for assigning a unique network address to a first node within a network which is arbitrarily connected. The first node may include a shared network resource, such as a networked printer device, or a modem, in addition to a stand-alone computer system. The network may include a network which is wireless, wherein various nodes comprise radio transceiver circuitry, including radio frequency modems. A first provisional network address for use in assigning the unique network address is determined by the first node. The first node broadcasts probes containing the provisional network address until a first probe response to one of the probes is received or a first interval of time elapses. If the first probe response to one of the probes is received, then the first node determines a second provisional network address and repeats selection of the address and broadcasting, until no probe response is received in the first interval of time. Using the first provisional network address, the first node broadcasts forward probes in the network until a second probe response to one of the forward probes is received by the first node or a second period of time has transpired. If a second probe response to one of the forward probes is received by the first node, then the first node determines a third provisional network address and repeats the steps of selecting, broadcasting probes and forward probes until no the response is received in the second interval of time. The final provisional network address may be used as the unique network address for the first node.
    • 一种用于将唯一网络地址分配给任意连接的网络内的第一节点的方法和装置。 除了独立的计算机系统之外,第一节点可以包括诸如联网的打印机设备或调制解调器之类的共享网络资源。 网络可以包括无线的网络,其中各种节点包括无线电收发器电路,包括射频调制解调器。 用于分配唯一网络地址的第一临时网络地址由第一节点确定。 第一节点广播包含临时网络地址的探测,直到接收到其中一个探测器的第一探测响应或经过第一时间间隔。 如果接收到对其中一个探测器的第一探测响应,则第一节点确定第二临时网络地址并重复地址和广播的选择,直到在第一时间间隔内没有接收到探测响应。 使用第一临时网络地址,第一节点在网络中广播前向探测,直到由第一节点接收到其中一个前向探测的第二探测响应或第二时间段已经发生。 如果由第一节点接收对其中一个前向探测的第二探测响应,则第一节点确定第三临时网络地址,并重复选择,广播探测和转发探测的步骤,直到在第二间隔中没有接收到响应 的时间。 最终的临时网络地址可以用作第一节点的唯一网络地址。
