Abstract: A dynamic orthotic device has a pair of rotating disks which are received in a base. Each disk houses a plurality of spherical foot-massaging balls. Each of the pair of disks is activated by a spring-biased pushbutton with arms mounted to a bottom edge of the pushbutton, each arm having a tine which engages a gear-toothed member affixed to the respective rotating disk and rotates them in opposite rotational directions. The massaging balls engage the soles of the wearer's feet in different locations with each respective step eliminating pressure buildup on the heels of the wearer.

Abstract: An automated blackjack table features a rotating ring with numbered stations (up to 21) matching the numbers at which the players are positioned. By pressing a foot pedal, the dealer can rotate the ring and rapidly deal a card to each passing numbered station allowing the density of players (and, hence the revenue stream) at each table to be tripled.
