Abstract: The present invention improves athletic performance by storing in a spring or elastic pad in the shoes, the energy expanded during the down-step movement of the athlete's leg; that energy is released subsequently, during the upward movement of the leg. It is shown that improvement of athletic performance takes place only when the rebound provided by the shoe is synchronized with the upward motion of the leg, i.e. when the period of oscillation of the spring or elastic pad, matches the frequency of up and down movement of the leg. The period of oscillation of a spring depends on the spring constant as well as on the compressing mass, and different sports activities require different periods of oscillation.

Abstract: A system for delivering audio, visual, or audiovisual entertainment, educational material and advertising to users of public and private restrooms, including visual images, and or sound programming, throughout the restroom or in discrete areas thereof, placed so that the images and/or sound can be conveniently seen and/or heard by users of these facilities. Optionally the system may be programmed to turn on when the restroom facilities are being used, and to be turned off either when the facility is vacated, or after a set time has elapsed.

Abstract: A razor that facilitates shaving effectiveness by effectively rendering the surface to be shaved taught. The razor comprises two or more surfaces wherein at least one of the surfaces is a cutting surface. The surfaces are inclined relative to each other, such that the skin and soft tissue in the area to be shaved is immobilized or pinched toward the cutting surface.
