Abstract: A hand formable rod, band or sheet, consisting of a plurality of elements which are linked together in such a way that the whole can be either very flexible, or semi-rigid, or rigid. In the band, the elements have six degrees of freedom, providing unusual flexibility. This fabrication may be hand formed to a desired shape and then rigidified to a substantial stiffness. In the rigid state, this fabrication is strong enough to retract living tissue, and to perform as a mold, template, or fixator. The rigidity may be varied in very small increments by using a screw or screws acting upon tensioning cables. Tension causes increased friction between sliding surfaces. This friction creates stiffness and strength. Bending the fabrication does not cause material fatigue.

Abstract: An apparatus for reproducing video, audio and accompanying characters, suitable for use as a sing-along or karaoke apparatus, uses pre-stored display patterns, such as animal figures, instead of video segments. Thus, the apparatus does not have to rely upon the availability of video software that contains song lyrics as well as matching video segments. The apparatus is inexpensive to manufacture since the hardware related to reading and processing an optical image recording disk is not needed. The apparatus also uses the animation patterns on the screen to inform users about the beginning of the music program. Specifically, the changes in the motion and moving speed of display patterns inform the user of the start time of a selected music program. The animation patterns may be displayed during introduction and intermission period, and even during music performance.
