An inverted tube bike frame with bottle opener gusset system is a bicycle frame with the top tube and down tube having a heightened profile with concave sidewalls and a bottle opener gusset strengthening the joint between the seat tube and the top tube. Each of the pages contains illustrative material, such as text andor pictures, and at least one of the pages is partially transparent, so that illustrative material on subsequent pages is visible to the reader through the transparent portion of the page. One aspect of the present invention is that a speech recognition meter is placed on the display near the insertion point where the user intends their speech to take effect. The data supplied to the hard disk drive are recorded in a disk, on the basis of such information, by a method conforming with the data. Because the rank-determining apparatus implements self-threshold decomposition, rank- and order-statistic based filters, such as the median filter, can be realized in a feasible manner. The insert extends into the passageway and engages the subgingival end of the prosthetic portion.
