DETAILED DESCRIPTION OF THE INVENTION
The following description with reference to the drawings provides illustrative examples of devices and methods according to embodiments of the invention. Such description is for illustrative purposes only and not for purposes of limiting the same.
The invention provides a game ball having a size and shape adapted to be passed among a number of players. An embodiment of a game ball 10 according to the invention is illustrated in FIGS. 1-2. The ball is depicted in the form of a football having an ellipsoidal shape. Other embodiments can include spherical forms such as a basketball, baseball, or soccer ball.
The game ball can be used to provide hours of entertainment among children and adults, and is a fin physical alternative to playing video games and watching television. The game ball can also be used to promote friendly competition among individuals and can be used like a conventional foam football during a pickup tag or a tackle game.
In an embodiment of the invention, the game ball is composed of a resilient material with a solid foam interior covered by a thin neoprene material to enhance durability. An example of a suitable material is a soft, flexible open-cell foam polyurethane or polyether from which soft impact balls and the like are made commonly sold under the NERF® line of products (Parker Brothers).
Housed in the interior of the game ball 10 are a microcontroller or microprocessor 12, a power source 14, a motion switch 16, and at least one of a sound generator 18, a vibration or motion generator 20 and a light generator (not shown). For proper weight and balance of the ball, the interior components are arranged along the axis and close to the center of the ball. FIG. 3 illustrates an embodiment of a schematic diagram of the electrical components of the game ball 10 in accordance with the present invention.
As illustrated, the motion switch 16 is connected to the microcontroller 12. The motion switch 16 is a motion responsive switch that is activated by moving the ball 10, for example, by picking up the ball and/or tossing the ball or, in some embodiments, by shaking the ball. An example of a suitable motion switch is a conventional ball sensor switch known in the art, which is structured with a spring having a fixed end and a free end and a metal cap or ball positioned proximate the free end of the spring for electrical engagement by the free end of the spring. Contact between the free end of the spring and the metal cap or ball closes an electrical circuit that generates a signal to the microcontroller 12.
An example of a suitable microcontroller 12 is a Texas Instruments (TI) MSP430 processor, which are low power 16 bit devices. The microprocessor 12 is electrically connected to the power source 14, which can be, for example, conventional batteries such as double A or triple A batteries or a long-lasting battery. In some embodiments, the microcontroller 12 incorporates internal counter/timer circuits that are used to generate random count periods for example, between 20-60 seconds (e.g., a 60-second count period, a 30-second count period, a 15-second count period, etc.). In other embodiments, a suitable logic and timing device such as a field programmable gate array (FPGA) or generic array logic (GAL) can be connected to the signaling devices. The timing feature allows the actual period of play to be an unknown variable.
The microcontroller 12 is also coupled to the sound generator 18 and/or the vibration generator 20 and/or a light generator (not shown), as known in the art. In some embodiments, the game ball 10 is structured with a microcontroller 12 coupled to a sound generator 18 and a light generator (not shown). As illustrated, the sound generator 18 can be mounted near the surface of the game ball to be clearly audible. The sound generator 18 can be, for example, a piezoelectric sound device such as a piezo speaker or a piezo buzzer, or other device capable of generating an audible sound such as a buzzing or beep. An example of a suitable vibration generator 20 is a pager vibrator or pager motor, cell phone vibrator, or other device capable of generating a physical signal (e.g., vibrate). Optionally, the ball 10 can include a light or a series or string of lights 22 embedded in or visible on the exterior surface and connected to the microcontroller. In some embodiments, the lights can be activated by a signal from the microcontroller to flash (e.g., in sequence) with a beeping sound and/or vibration. In embodiments of the game ball, the lights can be used in place of the sound generator and/or the vibration generator.
The design is such that the logic device will sense inactivity and switch itself off. Upon sensing activity, the logic will then switch itself back on, thus eliminating the need for an on/off switch to activate or turn off the device.
The game is played by two or more persons and the ball is passed or tossed from player to player in a modified version of the game “hot potato” to avoid having the ball when an alerting sound (e.g., rapid series of beeps) and/or vibrating mechanism is activated. At that time, the player holding the ball can be “smeared” by the other players (e.g., by tackling, tagging, etc.), or declared “out” or the “loser” of that particular play. In another variation, the player holding the game ball at the end of the play period would attempt to run to a “safe” spot or score a “touchdown” before being tagged or tackled by another player, with players keeping score.
To start the game, the game ball 10 is picked up by one person, which can activate the motion switch 16, which sends an electrical signal to the microcontroller 12 to start the timer. In some embodiments, the game ball 10 is shaken and/or tossed to activate the motion switch 16. The microprocessor also sends an electrical signal to the sound generator 18 such that, as the ball is being passed, a series of audible sounds (e.g., beeps or other sound) is generated to signal the various stages in the play of the game.
For example, during a first time period of the play, a steady series of beeps (or other sound) can be generated at a relatively low rate of speed (e.g., at 1 beep/second for 60-90 seconds). When the first time period expires, the microcontroller resets the timer and sends an electrical signal to the sound generator 18 to emit a series of beeps (or other sound) at an increased rate of speed for a random time period, which can be a shorter period of time (e.g., 1 beep/0.5 second for 30-60 seconds). When the second time period expires, the microcontroller resets the timer and sends a signal to the sound generator 18 to emit the sound at a further increased rate for a random time period (e.g., 1 beep/0.25 second or a continuous or rapid beeping sound for 10-15 seconds) to indicate the end of the play period. The microcontroller can further be configured to send a signal to a vibration generator 20 (where included in the game ball) to generate a vibrational motion, and/or a signal to a flashing light(s) 22 (where the game ball includes a light or series of lights).
After the third time period expires, picking up or otherwise moving the game ball 10 will then reactivate the motion switch 16 to restart the process by starting a new timing cycle and new play period, causing the players to quickly resume play and continue to pass the ball along.
The game ball allows individuals to play a more competitive and physical version of “hot potato” and can be used among neighborhood children and teens, as well as adults, at a variety of outdoor gatherings and events.
Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that any arrangement which is calculated to achieve the same purpose may be substituted for the specific embodiments shown. This application is intended to cover any adaptations or variations that operate according to the principles of the invention as described. Therefore, it is intended that this invention be limited only by the claims and the equivalents thereof.
