Title: Reducing the traffic involved in presence change notification between two networks by using watcher lists in network presence servers
Inventor: FUKAZAWA SHIGERU
IPC: H04L12/58
Filed: 2008-08-01
Abstract: A presence management system includes: a first presence server that controls a first network; a plurality of presentities that belong to the first network; a second presence server that controls a second network, the second network connected to the first network via a communication channel; and a plurality of watchers belonging to the second network; wherein the first presence server includes: a first watcher list that registers a given presentity under the first network associated with one of the watchers that requests presence information of the given presentity; and an external notification section that sends the presence information of the given presentity to the second presence server, and wherein the second presence server includes: a second watcher list that registers the one of watchers associated with the given presentity; and an internal notification section that sends the presence information to the one of watchers registered correspondingly to the given presentity. Thus, if a watcher and a presentity belong to different LANs (Local Area Network), the need for sending as many messages as the number of watchers to the IP network is eliminated, as the notification is sent only once.

Title: Filtering access to data objects
Inventor: CHEN JIANYU
IPC: G06F21/62
Filed: 2007-11-15
Abstract: In one embodiment, a code server and edit server are provided. The code server stores the source code. Users do not access the code server directly. Rather, an edit server is used where users can log in to the edit server and send requests to edit portions of the source code. The edit server then sends requests to the code server for requested portions of the source code. Different users may have different access rights to portions of the code. When the request is received from the edit server, if the code server determines the user requesting the portion of the source code does not have access rights to it, then the code server does not allow the portion of code to be accessed. However, if the user does have access rights, then the portion of the source code is retrieved and sent to the edit server. The user can then edit the source code on the edit server.

Abstract: 499,558. Pitch and tar. KRUPP AKT.-GES., F. April 5, 1938, No. 10393. Convention date, May 21, 1937. [Class 55 (ii)] In the production of a fuel or motor oil of constant composition, all the tar fractions separately deposited and collected on the distillation or gasefication of a solid fuel are mixed together in the same proportions by volume of the quantities of each fraction collected in determined time intervals and are purified by centrifuging before or after mixing. The purification is preferable before admixture when the specific gravity of the resulting mixture is nearly 1À00, and is preferably operated in the absence of air, such as by passing hot or cold coke-oven gas or low temperature distillation gas through the centrifuge. The tar in the latter may be heated to optionally remove the light oils and vacuum may be applied. The resulting tar may be blended with fractions from another fuel gasefication ; an example comprises the blending of the fractions deposited from a low and a high temperature distillation respectively in constant weight ratio to each other. Specification 257,560, [Class 55 (ii)], is referred to.
