Abstract: A gyroscopic figurine (10) is disclosed having a body (11) and a gyroscope (12) mounted within the body. The gyroscope (12) has a rotatable wheel (15) coupled with the shaft (23) of an electric motor (16). The shaft is oriented at an angle to the axis of rotation (21) of the gyroscope wheel to cause a slight unbalancing or wobbling effect as the wheel rotates. The body has a torso (26), a head (28), pivoting arms (29), a fixed leg (30), and a moveable leg (33). The relative positioning of the arms, legs and torso cause the figurine to become unbalanced and thus move while the gyroscope operates. The unbalancing of the gyroscopic wheel causes the figurine to vibrate and thus enhance the skating effect of the figurine upon an underlying surface.

Abstract: A rocket (100) is disclosed having a body (101) with a bay (102) therein and a latchable hatch (109) which is movable between a bay opened position and a bay closed position by a spring biased hinge (110).

Abstract: A sound-generating unit (30) is encased within the body (20) of an article (10) which is to be launched by a burst of compressed and/or pressurized fluid (15) from a fluid launching device (11). The sound-generating unit (30) has the three main elements of a piezoelectric electromechanical transducer (32), a sound-generator electronic circuit (40), and a speaker (42). The body (20) of the article to be launched has a bore to receive the burst of fluid (15). The piezoelectric element (32) is positioned within the bore in alignment for receiving the impact of the burst of fluid (15). The piezoelectric element (32), the speaker (42) and an electrical energizer (36) are connected to the sound-generator circuit (40). Upon being impinged by a burst of fluid (15) projected into the bore of the body (20), the piezoelectric element (32) minutely deforms and generates a voltage that is processed by the sound-generator circuit (40) into a desired sound-effect signal that drives the speaker (42).

Abstract: A water gun (10) is provided having a storage tank (18), a expandable pressure tank (19) having an elastic bladder (30) encased within an outer shell (29), and a pump (32) for conveying liquid from the storage tank to the expandable pressure tank. The conveyance of liquid into the expandable pressure tank causes the liquid to be pressurized by the biasing force of the elastic bladder. The pressurized liquid is released through a nozzle (21) coupled to the expandable pressure tank by actuation of a trigger (17). The storage tank may be collapsible to prevent the storage of air therein or be coupled to a fluid selective check valve to prevent air from being pumped into the pressure tank.

Abstract: A water gun (10) is provided having a pressure tank (19) in fluid communication with a coupler (20) adapted to be received upon a conventional water faucet, and a pump (42) for conveying additional air to the pressure tank. The flow of water from the water faucet draws ambient air which is compressed within the pressure tank to pressurize the water therein. The pressurized liquid is released through a nozzle (21) coupled to the pressure tank by actuation of a trigger (17).

Abstract: A wet diaper detector comprises an elongated strip of material sized to be positioned in a diaper with a portion of the strip residing in a region of the diaper subject to wetness and an end of the strip protruding from the diaper at the upper rear or front portion thereof. The strip carries a pair of spaced conductors that extend along the length of the strip and terminate at the protruding end thereof. A detector and alarm assembly is adapted to be releasably coupled to the protruding end of the elongated strip and is configured to monitor the electrical resistance between the spaced conductors of the strip. When the diaper is wet by its wearer, the resistance between the spaced conductors of the strips falls below a pre-established value whereupon the detector activates the alarm to alert an attendant to change the diaper. In one embodiment, wetness is detected capacitively.
