    摘要： A power saving vacuuming pump system is based on complete-bearing-sealing and dry-large-pressure-difference root vacuuming root pumps includes an input valve at an input end of a vacuum space for receiving gas mixture of saturation water vapor and non-condensed air from a condenser of a power plant; a first root vacuum pump connected to the input valve for receiving gas mixture from the input valve and then compressing the gas mixture; a second root vacuum pump connected to the first root vacuum pump for receiving gas mixture from the first root vacuum pump and then compressing the gas mixture. Inner connection walls between the vacuum chamber and the two bearing rooms are installed respective bearings which are installed to be around the driving shaft, and thus all the vacuum chamber and the two bearing rooms are tightly sealed. The vacuum chamber is completely dried so as to prevent from internal emulsion.

    摘要： A method, which provides a location context to an online object, includes (a) receiving identification information regarding the online object; (b) in a database, creating a relationship between the online object and a representation of a geographical location; (c) receiving a request for retrieving the relationship from the database based on the identification information or the geographical location; and (d) responding to the request by returning the relationship retrieved from the database. The request may originate from an application program that displays the representation of the geographical location graphically. The online object may correspond to an online business. In some implementations, the online object is unrelated in real life to a community located at the geographical location.

    摘要： In general, in one aspect, the disclosure describes a Universal Plug and Play (UPnP) Remote Access Server (RAS) to provide a communication channel between UPnP Remote Access Clients (RACs) connected thereto. The UPnP RAS maintains local discovery information for UPnP devices connected to a local network and remote discovery information for remote UPnP devices communicating therewith. The UPnP RAS provides the remote UPnP devices communicating therewith with the local discovery information and the remote discovery information. The remote discovery information is utilized by a first remote UPnP device to discover a second UPnP device and vice versa. After discovery, a first remote UPnP device can communicate with a second UPnP device and vice versa.
