Abstract: The present invention comprises an inflatable balloon of sufficient volume and buoyancy to allow a human pilot to float above the ground and to glide over the ground within an enclosed area. The balloon incorporates several safety features that permit it to be used for recreation, including a prop-bike to enable the user to propel the balloon.

Abstract: A vocabulary teaching aid system generally includes a computer that is operably connected to a video monitor and one or more user-interactive peripherals, e.g., keyboard or mouse. The computer operates under direction of a program whose directions include providing an interactive screen presentation on the video monitor, providing for selection of a desired vocabulary word from the screen presentation through use of the user-interactive peripheral, and presenting an example of usage of the selected vocabulary word on the video monitor.

Abstract: A real-size simulated drag strip ride is presented which recreates the physical and visual sensations of a drag race. A pair of real-size dragsters are positioned along specified and controlled parallel linear tracks. The occupant is positioned inside the driver's compartment, with a full safety harness securing him in place in an adjustable seat. The invention includes audio sounds of ignition, “burn-out” and acceleration simulating a drag strip race, as well as simulated smoke from the “burn out” portion of the race preparation. Once the simulated light tower signals that the dragster is set to race, each driver of two, side-by-side vehicles pushes the acceleration pedal to accelerate the vehicle through an initial acceleration zone. The dragsters are propelled by use of a pneumatically powered piston attached to a cable located out of sight underneath the vehicle. The race is finished when the cars pass the finish line. Speeds and the winner are displayed on the starting line tower.

Abstract: A seat recline mechanism for a child swing includes at least one latch, positioned on a side of a seat back of the swing, and first and second latch-receiving members, positioned on a hanger arm of the swing. The latch is configured to engage the first latch-receiving member to position the seat back in a first in-use position, and the latch is configured to engage the second latch-receiving member to position the seat back in a second in-use position in which the seat back is adjusted rearward relative to the first in-use position.
