Abstract: A method of sending data from a source node in a wireless communications network is provided. In an example, the method includes selecting one of a plurality of available routing paths, from the source node to a destination node, on which to send data based on routing criteria specified by the source node.

Abstract: The present invention relates to a calendar event notifying method for calendar event prompt system. The calendar prompt system includes a calendar server (101) and a plurality of supporting devices for connecting the calendar server (101) to a plurality of receivers of a user, the calendar event notifying method comprising: calculating step of calculating and generating a receiver list for the user (S301); sending step of sending an event notification message to one or more receivers listed in the receiver list (S302); determining step of determining whether the one or more receivers have returned at least one notification confirmation message in a pre-determined time (S303); removing step of removing the one or more receivers from the receiver list if none of the one or more receivers returns a notification confirmation message (S304); and repeating the sending step and the determining step until at least one receiver returns a notification confirmation message.

Abstract: An index building, querying method, device and system for distributed columnar database are provided. The index building method for distributed columnar database includes: obtaining a column field from a distributed columnar database, generating a column index file in which the column field is a key word, the column index file comprising the mapping relationship between the value of the column field in the distributed columnar database and the corresponding Row field value; storing the column index file to a index catalogue corresponding to the column field in the distributed columnar database.

Abstract: A cleaning solution for cleaning stainless steels etched by ferric or ferrous salt solution is provided. The cleaning solution including: one or more ingredients selected from a group consisting of inorganic acid, inorganic alkali metal salt, and inorganic alkaline-earth metal salt in a concentration of about 200-600 g/L; complexant being capable of complexing with ferric or ferrous ions in a concentration of about 26-275 g/L; and one of carboxylic acid and carboxylate, or a combination thereof, in a concentration of about 75-250 g/L. A method for cleaning the stainless steels is also described there.

Abstract: Methods of routing data within a wireless communication system are provided. In the example methods and system, data packets may be routed to and/or between any node within a Mobile Ad-Hoc Network (MANET), such as a network running Ad-hoc On-demand Distance Vector (AODV) protocol, and an external connection or device (e.g., an Internet entity) if at least one node within the MANET includes a connection to the external connection or device. Accordingly, a single “connected” MANET node may share its external connections with non-connected nodes.

Abstract: In an embodiment of a method for registering a first device in a mobile ad-hoc network (MANET), a registration message is sent to 1-hop neighboring devices. The registration message includes a hop-limit and a freshness indicator of the first device. The freshness indicator indicates an experience level of the first device in the MANET, and the hop-limit indicates a limit on the number of hops for forwarding the registration message. According to another embodiment, a registration message of the first device is received. The registration message includes a first freshness indicator, and the first freshness indicator indicates the freshness of the registration message. Based on the received registration message, a reverse registration message may be sent and/or the registration message may be forwarded to other devices.

In an example, the method includes selecting one of a plurality of available routing paths, from the source node to a destination node, on which to send data based on routing criteria specified by the source node.

Abstract: The method manages, for example, a database to track customer service sessions over a plurality of communication media used by a customer.
