Abstract: Techniques for previewing a content package file through a portal interface before the file is imported to the portal server computer are provided. A content package file is a relational data structure that contains references to a first level of content files. The first level content files within the content package file can contain references to second level content files, the second level content files can contain references to third level content files, etc. The references to the content files are replaced with content from the content files. Information about the content files is displayed in a preview format through a portal interface before the content files are imported. The user can be notified if any of the references to content files contain errors.

Abstract: The present invention describes an adjustable telescopic leg system that is adapted to fit on at least one of a plurality of supporting side members that are connected to each other and rest on a ground surface. The adjustable telescopic leg system comprises at least one longitudinally adjustable telescopic leg having a sawtooth-like structure facing towards a latch. The sawtooth-like structure may be formed by a plurality of depressions on the adjustable telescopic leg. The latch may be adapted to fit tightly between an upper edge and a lower edge of the depressions. The adjustable telescopic leg system may further comprise a fixation rod connecting the latch with a release handle for longitudinally adjusting the position of the adjustable leg.

Abstract: Techniques are provided for importing a content package file that contains references to content files over a network. A content package file is compressed and bundled together with its related content file. The compressed file is then transferred to over a network to a server in one communication to save time. The compressed file is then decompressed, and the content files imported from the server machine location. The content files are placed into the same subdirectories according to how they were previously organized. A user can browse for compressed content package file in a more intuitive way without having to identify the machine name that the content files are stored in.

Abstract: A projectile is described, which changes its shape upon impact on a target and thereby reduces the danger of penetration into a living target. The projectile is useful for the identification of individuals in crowds, by filling it with staining material which stains the target upon impact, and may further contain other liquid or gaseous materials, such as tear gas. The projectile of the invention is further useful for different uses, such as for gunfight simulation.
