Abstract: Provided is a method for folding a foldable display device, in which the foldable display device includes a base panel plate, wherein a second panel plate hinged to one side of the base panel plate is folded, and a first panel plate hinged to the other side of the base panel plate is folded, and the first and second panel plates are unfolded, so that portions of a display panel, which are repeatedly folded and unfolded, can be stably supported, the display panel can be prevented from being damaged, and a thickness of the foldable display device can be thinner than a foldable smartphone folded once so that a volume thereof can be minimized, thereby providing a display panel that becomes wider when the first and second panel plates are unfolded.

Abstract: A new and improved shock absorption mechanism for shoes comprising a plurality of members defining an upper support planar surface and a lower support planar surface. The upper planar surface and lower planar surface are moveable toward and away from each other. A plurality of near-collapsible members are operatively connected between the upper and lower planar surfaces. The collapsible members are moveable between an extended position and a collapsed position. Each of the collapsible members has a spring associated therewith for urging the members into their extended position. The plurality of members and the collapsible members are connected and positioned within a collapsible heel of a shoe. The springs have a spring constant sufficient to support the weight of the wearer of the shoe and to absorb the shock when a forceful impact is exerted on the members which urge the members together against the urging of the springs, whereby both the acceleration and the velocity of said members is gradually reduced to zero.
