Abstract:
A lightweight folding chair may include one or more armrest. The armrests are preferably pivotally attached to the chair so that the armrests can be moved between a storage position and a use position. The armrests are also preferably pivotally connected to the front legs of the chair, but the armrests can be connected to any suitable portions of the chair. The chair may also include a seat with an interference fit support bracket. The seat may have a lightweight seat member constructed of a lightweight material, such as a blow-molded plastic, that is generally supported by two such support brackets. The support brackets may be affixed to the lightweight seat member by sliding the lightweight seat member into interference engagement with the support brackets.
Abstract:
A personal table is provided having a table top supported by a support assembly. The table top is preferably constructed from blow-molded plastic and the support assembly preferably includes a first leg and a second leg that are pivotally connected. The legs desirably have a generally X-shaped configuration when the legs are placed in an upright position and the legs can be collapsed into a storage position. Each of the legs may include a lower portion, a body portion and an upper portion that is preferably selectively connected to the table top. The legs, for example, can be connected to the table top by inserting the upper portions of the legs into leg receiving recess formed in the table top. The leg receiving recesses are preferably integrally formed in the bottom surface of the table top as part of a one-piece construction. Desirably, a plurality of leg receiving recesses are formed in the bottom surface of the table top and the legs can be selectively attached to the leg receiving recesses in order to vary the height of the table.
Abstract:
A method and apparatus for searching an electronically stored table of information including a plurality of table entries and facilitating high speed searching of a table to provide a longest matching entry. The table searching method uses at least one memory unit having a table of information including a plurality of data entries. The table of information has a plurality of search keys associated with the plurality of data entries and the plurality of search keys form a tree structure based on a prefix length for each of the search keys. The plurality of search keys are expanded such that each of the plurality of search keys has two lowest level search keys associated therewith that cover a lowest level of the tree structure. A binary search of the lowest level search keys is performed based on a search value to determine a longest prefix match. A data entry of the plurality of data entries is output based on said longest prefix match. The method is also applicable to routing data in an internet router where the routing of data packets depends on address information stored in the table of information.
