Abstract: A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a seam, overlaying the seam with a tape made of the same selected material, and sealing the tape and seam using a radio frequency (RF) welding machine.

Abstract: A magnetic electron exciter includes a rotor adapted to be rotated within a preselected range of rotational speeds, and having a plurality of magnets mounted therein preselected distances from the rotational axis of the rotor. A plurality of coils are positioned adjacent to the rotor, whereby rotation of the rotor creates an electrical current in the coils. First and second electrodes are spaced apart a predetermined distance, and are electrically connected with the coils to create an arc between the electrodes when the rotor is rotated relative to the coils.

Abstract: A collectable card game of strategy and skill that includes a plurality of collectable cards, each of which preferably comprise a character-specific collectable card. Each collectable card corresponds to a character and contains character specific information regarding the character, including attributes and capabilities of the character such as offensive and defensive characteristics and assigned values. Each collectable card is adaptable from a generally flat configuration to a folded configuration generally in the form of a “fortune teller” novelty piece that functions during play as a functional game piece. Once each player has configured his collectable card into the game piece configuration, the players engage in a battle that consists of a series of rounds. During each round, the players engage in a series of alternating offensive strikes and mitigating defensive plays, the combined net score of which is then deducted from a predetermined “life force” value assigned with each character card.
