Abstract: IP addresses included in a route table are segmented so as to be able to be retrieved all together, and are retrieved at a high rate. As means for retrieving the IP address, a pointer table 200, a secondary pointer table, a local table, and a route table are provided, and a table with a numerical value comparing function is also provided when the further segmentation is necessary. In the retrieval for the ACL table, a fixed length data table of fixed length data configured in the ACL table is generated, and the ACL table is retrieved by using a retrieving method for retrieving the route table. Such tables are provided with a table manager 600 as means for efficiently composing and managing the table, and managing to prevent the retrieving operation from being obstructed.
Abstract: Fixed-length data (560) contained in a database (560) are segmented into a number of pieces of data that are searchable at a time and searching is performed at high speed. As means for it, a pointer table (500), a secondary pointer table, a local table, and a fixed-length-data table are provided, and when more segmentation is required, a table having a numeric-value comparing function is further provided. As means for performing efficient configuration/management of the tables and for performing management that does not interfere with a search operation, an empty-house table (700), an empty-room table (720), a room-management table (740), and a structure-management table (760) may be provided.
Abstract: A system and method for mixing gaseous fuel with air prior to combustion in an internal combustion engine. The system includes an L-shaped channel with a cap mounted to one end and an inlet formed at the other end. A plurality of holes is formed in the L-shaped channel. The channel is mounted to the air intake system of the internal combustion engine upstream from the air filter such that a partial vacuum is created in the vicinity of the holes as the incoming air flows past the channel. The channel includes means for regulating the flow of gaseous fuel through the channel.
