Abstract: A sports detection and reporting system that locates the players and the ball to determined if certain play criteria have been met. The system also displays on the field detected locations relevant to the players and the play in real time.

Abstract: Toy water guns include a housing supporting a liquid storage reservoir, a conduit for establishing fluid communication between the reservoir and a discharge orifice disposed proximate a front end of the housing, a trigger mechanism, a fluid transfer system adapted to develop forces for causing a continuous or pulsed stream of liquid to flow through the conduit and out of the discharge orifice when the trigger is pressed. An illustrative embodiment employs a nozzle translation assembly that is dimensioned and arranged to move the discharge orifice along a time varying path relative to the housing as a stream of liquid is discharged. The time varying path may be circular, as to obtain a helical or spiral flow pattern or non-circular as to obtain, for example, a zig-zagging or figure eight pattern.

Abstract: A dispensing system for dispensing a viscous, flowable product such, for example, as a spin-art paint solution, comprises an axially extending container that defines an opening and an interior chamber for receiving and storing the flowable product. A discharge assembly is coupled to the container, the discharge assembly being dimensioned and arranged to spin, relative to the container, as it receives the flowable product from the interior chamber. The spinning motion of the discharge assembly, which may be accompanied by a linear movement of the container itself relative to a target surface, allows the user to cleanly and evenly distribute the flowable material onto a target substrate in an attractive, curvilinear deposit pattern. Optionally, the discharge assembly may be configured with a pivoting nozzle that can be moved from a position for obtaining a helical (curvilinear) deposit pattern to a position for obtaining a rectilinear deposit pattern.

Abstract: A water discharging amusement device incorporates a housing defining an interior chamber, an inlet conduit dimensioned and arranged to receive water from a source of pressurized water and to direct received pressured water into the interior chamber, a rotatable nozzle assembly dimensioned and arranged to spin while receiving pressurized water from the interior chamber and to eject a substantially spiral stream of water as it spins, and a drive assembly disposed within the chamber and dimensioned and arranged to convert linear forces imparted by pressurized water arriving via the inlet into rotary forces for rotating the rotatable nozzle.

Abstract: A dispensing system for dispensing a viscous, flowable food product such, for example, as a condiment, comprises an axially extending container that defines an opening and an interior chamber for receiving and storing the food product. A discharge assembly is coupled to the container, the discharge assembly being dimensioned and arranged to spin, relative to the container, as it receives the viscous food product from the interior chamber. The spinning motion of the discharge assembly, accompanied by a linear movement of the container itself relative to a target food item, allows the user to cleanly and evenly distribute the flowable food material onto the target item in an attractive, curvilinear deposit pattern. Optionally, the discharge assembly may be configured with a pivoting nozzle that can be moved from a position for obtaining a helical (curvilinear) deposit pattern to a position for obtaining a rectilinear deposit pattern.

Abstract: A temporary visible image, such as a first down reference line, corporate logo, or text is projected onto a target surface by an orientation-stabilized, fiber-fed laser projector. The projector may include at least one cylindrical lens or at least one pair of X-Y scanners. One or more remotely located lasers, supplying optical energy at a single wavelength to the projector, accommodate projection of a monochromatic line pattern. Multi-colored images are accommodated by supplying, to the projector, the output of a plurality of lasers operating at different wavelengths within the visible band. The projector is suspended and conveyed as a unitary assembly by a suspension system adapted to maintain the projectors angular orientation and dynamically stabilize the image. If desired, two or more independently-suspended projection modules or groups of modules adapted to move in unison or independently over the length of the field may be employed.

Abstract: An attachment for converting an air-pressure water gun to a device ejecting projectiles by air pressure includes a hollow barrel portion having structures on the first end portion for fitting over the barrel of an air-pressure water gun. A hollow needle pin is adapted to the fitted within the nozzle of the water gun, and a tube extends from the needle pin to the interior of the first end portion of the barrel to deliver pressurized air from the water gun into the barrel to eject projectiles therefrom.

Abstract: A device for producing bubbles from water pressure which may be used in connection with a sprinkler includes a turbine, and means for connecting a turbine to a source of pressurized water for rotating the turbine. Structures are provided which include a fan rotated by motive power from the turbine, and a container for a solution capable of forming bubbles is provided with a dipper having at least one opening positioned under motive power of the turbine to place the openings sequentially within the container and thereafter into the flow of air created by the fan.

Abstract: A water gun having a water reservior adapted to be partially filed with water includes a piston pump having an outlet connected to the water reservior. A hand-operated slide member can be reciprocated by an operator for the water gun, and a rack connected to the slide member drives a gear train connected to a flywheel. The flywheel is connected through a crank wheel to the piston of the piston pump, and as the operator withdraws the slide member to rotate the flywheel, the piston is reciprocated back and forth within the piston chamber of the pump to drive air into the water reservior. The flywheel maintains the reciprocating motion of the piston as the operator slides the slide member forward in preparation for another stroke. In this way, the pumping action is maintained by the flywheel as the operator reciprocates the slide member forward to begin another stroke.

Abstract: A toy water gun is provided with a battery driven motor and pump assembled with a chamber communicating with a water reservoir and a nozzle in the gun. When the motor and pump are energized, intake and exit valves operate alternately to determine a series of spurts of water from the chamber through the nozzle.
