Abstract: A method and apparatus for reverting a disk drive to an earlier point in time is disclosed. Changes made to the drive are saved in a circular history buffer which includes the old data, the time it was replaced by new data, and the original location of the data. The circular history buffer may also be implemented by saving new data elements into new locations and leaving the old data elements in their original locations. References to the new data elements are mapped to the new location. The disk drive is reverted to an earlier point in time by replacing the new data elements with the original data elements retrieved from the history buffer, or in the case of the other embodiment, reads to the disk are mapped to the old data elements stilled stored in their original locations. The method and apparatus may be implemented as part of an operating system, or as a separate program, or in the controller for the disk drive. The method and apparatus are applicable to other forms of data storage as well.

Abstract: A stackable arm chair is constructed from the combination of a frame which supports woven material to form the chair's seat, back and side arm portions. Openings provided in the side arm portions enable passage of the rear legs of an adjacent arm chair to provide a nested forward stack occupying a minimum of volume. The openings are configured and dimensioned so as to cooperate with a conventional cushion to block the openings from view thereby eliminating the conventional stackable chair appearance.

Abstract: A polymer wicker-like yarn used in the fabrication of furniture and other items has a groove on the outer surface extending in an axial direction along the yarn. The groove may be interrupted or may wobble along the axis of the yarn. The yarn may also have a stripe extending along its axis, which may wobble and/or intersect the groove at various points along the stripe. A woven material having a wicker look incorporates the wicker-like yarn as the weft yarn and may incorporate the wicker-like yarn as the warp yarn. An article of furniture having a wicker look incorporates panels of the material.
