Handheld electronic game with recharging function

Abstract

A handheld electronic game comprises a rotational body, an processor, a storage cell for powering the processor, a display screen for displaying images processed by the processor, and a number of keys for providing game-control input to the processor. A generator is electrically connected to the storage cell for applying voltage to and recharging the storage cell. There is also a flywheel rotatably with respect to the body, which is connected to the generator and provides a mass moment of inertia enabling rotation of the body relative thereto during dynamic rotational movement of the body.

1 . A handheld electronic game, comprising: 
 a rotational body;    an processor within the body;    a storage cell within the body for powering the processor;    a display screen upon the body for displaying images processed by the processor;    a number of keys for providing game-control input to the processor;    a generator electrically connected to the storage cell for applying voltage to and recharging the storage cell; and    a flywheel rotatably with respect to the body and connected to the generator and providing a mass moment of inertia enabling rotation of the body relative thereto during dynamic rotational movement of the body.    
   
   
       2 . The game as claimed in  claim 1 , wherein the body comprises a first wheel and a second wheel fixed together by a spindle from which a string can extend.  
   
   
       3 . The game as claimed in  claim 2 , wherein the processor, the storage cell, the display screen and the keys are located within the first wheel, and the generator and the flywheel is located within the second wheel.  
   
   
       4 . The game as claimed in  claim 1 , further comprising a circuit board to which the processor, the display screen and the keys are mounted.  
   
   
       5 . The game as claimed in  claim 1 , wherein the storage cell comprises a rechargeable battery.  
   
   
       6 . The game as claimed in  claim 1 , wherein the generator comprises a coil electrically connected to the storage cell and a magnet rotatable within the coil to induce a voltage in the coil for recharging the storage cell.  
   
   
       7 . The game as claimed in  claim 6 , wherein the magnet is mounted on a shaft to which the flywheel is mounted for rotation therewith.  
   
   
       8 . The game as claimed in  claim 1 , wherein a voltage regulator is electrically connected between the generator and the storage cell to ensure that the voltage applied to the storage cell is always in the right polarity.  
   
   
       9 . The game as claimed in  claim 1 , wherein the voltage regulator comprises a diode.  
   
   
       10 . The game as claimed in  claim 1 , further comprising a speaker connected to the processor for receiving a sound signal therefrom and reproducing the sound.
