Abstract: A system, method, and apparatus for air delivery. A formable mask having an oxygen supply port and exhaled air removal components for the delivery of oxygen enriched air to a user. The formable mask includes formable components and materials to increase comfort and minimize chafing of a wearer. The formable mask further includes a harness to hold the mask in position on a user's head, where said harness minimizes chafing of the user. An oxygen delivery system uses the formable mask and oxygen supply components. Oxygen supply components include a flow rate throttling valve and an O2 reservoir to conserve O2 use and insure O2 availability to a patient. A method of using the air delivery system.

Abstract: A system, method, and apparatus for air delivery. A cannula having a low velocity airflow and efficient air delivery system. The cannula includes at least one compartment to reduce airflow velocity and nostril inserts. The cannula may further include moldable components and materials to increase comfort and minimize chafing of a wearer. The cannula further may include a head strap to hold the mask in position on a user's head, where said harness minimizes chafing of the user.

Abstract: A system, method, and apparatus for modified air delivery. A formable mask having an oxygen supply port and exhaled air removal components for the delivery of modified air to a user. An oxygen delivery system uses the formable mask and oxygen supply components. Oxygen supply components include a flow rate throttling valve and an O2 reservoir to conserve O2 use and insure O2 availability to a patient. The system modifies the air for delivery using an air modification module to condition the air for delivery of aerosolized particles to the user.

Abstract: A belt drive system for use in a positive drive application includes a transmission belt having a row of drive teeth spaced apart along a first side and a non-toothed opposite second side. The system includes a driver pulley, a counter-rotating driven pulley or pulleys, and the transmission belt. The counter-rotation is achieved by the incorporation of a 180 degree twist in a belt span between the driver pulley and the driven pulley and a recovery twist in a second belt span from the driven pulley back to the driver pulley.

Abstract: A drive system comprising a driver pulley, a driven pulley (22), and a belt (10). The belt (10) has a pulley engaging surface (16) comprised of a plurality of transversely extending self-tracking teeth (18). The driven pulley (22) has a non-grooved, crownless belt engaging surface (24). The material (20) forming the pulley engaging surface (16) of the belt (10) having a relatively low coefficient of friction, and the material (28) forming the belt engaging surface (24) of the driven pulley (22) having a relatively high coefficient of friction.

Abstract: An integral spin cast and flipping target pad comprising a base portion and an open top, generally cylindrical, target portion extending upwardly from the base. Preferably, the target cylinder is shaped like a fish head and the base defines lily pad shapes in its upper surface. The base comprises a bottom portion, a top portion and an edge portion extending between the bottom and the top defining a flotation cavity within the base. Alternatively, the base may be made of decorative wood. The target cylinder comprises a generally cylindrical wall extending upwardly from the top portion of the base. The wall can be comprised of spaced apart generally cylindrical outer and inner wall portions extending upwardly from the top portion of the base and a lip portion extending between a top of the inner wall and a top of the outer wall. Preferably, gussets extend from the target cylinder to the top of the base. These gussets are shaped like fish fins associated with the fish head shaped target cylinder.
