Abstract: The REGRIPPER traction pad kit is to make traction pads reusable by adding a hook and loop style bonding like Velcro (registered trade mark) for instance, to the bottom of any traction pad and the top of any surfboard. Traction pads that are available on the market are fixed permanently by adhesive to a surfboard and are good for only one surfboard. The REGRIPPER traction pad kit can be used on many surfboards. The hook side is added to a traction pad by adhesive and the loop side is added to a surfboard by adhesive. By adding the loop side to additional surfboards the REGRIPPER traction pad can be peeled off one surfboard and placed on another surfboard. The REGRIPPER traction pad kit will have four, fourteen inch by four inch strips each of hook side and loop side for a larger traction pad and three fourteen by four inch strips each of hook side and loop side for smaller traction pads. A loop side will be also available by itself for additional surfboards in a separate kit.

Abstract: A method to sequentially deduplicate data, wherein the method receives a plurality of computer files, wherein each of the plurality of computer files comprises a label comprising a file name, a file type, a version number, and file size, and stores that plurality of computer files in a deduplication queue. The method then identifies a subset of the plurality of computer files, wherein each file of the subset comprises the same file name but a different version number, and wherein the subset comprises a maximum count of version numbers, and wherein the subset comprises a portion of the plurality of computer files. The method deduplicates the subset using a hash algorithm, and removes the subset from said deduplication queue.
