Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to battery with traveling disk&#39;s function adopted for use on portable electrical apparatus and particularly to a battery with traveling disk&#39;s function for storing and retrieving data.  
       BACKGROUND OF THE INVENTION  
       [0002]     In the past, electrical apparatus had to be plugged into a power supply socket to receive electric power. Nowadays most electrical apparatus are portable. These portable electrical apparatus are powered by batteries.  
         [0003]     Most batteries merely provide an electric power supply function. Some batteries offer a vibration function to shake the portable electrical apparatus. Aside from this, the battery offers a few other functions.  
       SUMMARY OF THE INVENTION  
       [0004]     The primary object of the present invention is to provide a battery with traveling disk&#39;s function for storing and retrieving data.  
         [0005]     The battery with traveling disk&#39;s function according to the invention may be selectively connected to portable electrical apparatus or electrical apparatus. The battery with traveling disk&#39;s function includes a first connector, a controller, a memory, a transmission interface and a second connector. The first connector may be selectively and electrically connected to a portable electrical apparatus. The controller is connected to the first connector to transmit data. The memory is connected to the controller to store data. The transmission interface is connected to the controller to transmit data. The second connector is connected to the transmission interface to, selectively and electrically, connect to an electrical apparatus. The battery with traveling disk&#39;s function thus constructed can store and retrieve data.  
         [0006]     Therefore, the battery with traveling disk&#39;s function according to the invention can be connected electrically to a portable electrical apparatus. When transmitting data, the first connector is electrically connected to the portable electrical apparatus. The portable electrical apparatus can retrieve data stored in the memory through the controller. On the other hand, when the battery of the invention is electrically connected to the electrical apparatus for data transmission, the second connector is connected electrically to the electrical apparatus so that the electrical apparatus can retrieve the data stored in the memory through the transmission interface and the controller.  
         [0007]     The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0010]     Referring to  FIGS. 1 and 2 , the battery with traveling disk&#39;s function  20  according to the invention aims to be selectively connected to a portable electrical apparatus  10  (a handset is shown in the drawings) or an electrical apparatus (such as a personal computer and notebook computer, not shown in the drawings). The invention includes a first connector  21 , a controller  22 , a memory  23 , a transmission interface  24 , a second connector  25 , a battery module  26  and a voltage regulator  27 .  
         [0011]     The techniques for data transmission between the battery with traveling disk&#39;s function  20 , the portable electrical apparatus  10  and an electrical apparatus are first discussed as follows. The first connector  21  may be selectively and electrically connected to the portable electrical apparatus  10 . The controller  22  is connected to the first connector  21  to transmit data. The memory  23  is connected to the controller  22  to store data. The transmission interface  24  is a universal serial bus (USB) connecting to the controller  22  to transmit data. The second connector  25  is connected to the transmission interface  24  to, selectively and electrically, connect to an electrical apparatus.  
         [0012]     Hence the battery with traveling disk&#39;s function  20  can be connected electrically to the portable electrical apparatus  10 . For data transmission, the first connector  21  is connected electrically to the portable electrical apparatus  10 , meanwhile, the portable electrical apparatus  10  can retrieve data stored in the memory  23  through the controller  22 .  
         [0013]     On the other hand, the battery with traveling disk&#39;s function  20  according to the invention may be connected electrically to an electrical apparatus. For data transmission, the second connector  25  is connected electrically to the electrical apparatus, meanwhile, the electrical apparatus can retrieve data stored in the memory  23  through the transmission interface  24  and the controller  22 .  
         [0014]     When the battery with traveling disk&#39;s function  20  delivers electric power, the battery module  26  is connected to the first connector  21  to provide electric power for the portable electrical apparatus  10 . The voltage regulator  27  is connected to the battery module  26 , first connector  21 , controller  22  and memory  23  to obtain electric power and regulate the voltage, and delivers electric power to the first connector  21 , controller  22  and memory  23 . The battery module  26  is connected to the transmission interface  24  so that when the second connector  25  is electrically connected to the electrical apparatus, electric power is delivered, through the transmission interface  24 , to the battery module  26  for storing electric power.  
         [0015]     Thus when the battery with traveling disk&#39;s function  20  is electrically connected to the portable electrical apparatus  10  and delivers electric power, the first connector  21  may be electrically connected to the portable electrical apparatus  10 . Meanwhile, the battery module  26  may deliver electric power to the voltage regulator  27 , which regulates the voltage and delivers electric power to the first connector  21 , controller  22  and memory  23  to provide the electric power required. Of course, because the first connector  21  is electrically connected to the portable electrical apparatus  10 , the portable electrical apparatus  10  has electric power needed during operation.  
         [0016]     On the other hand, the battery with traveling disk&#39;s function  20  is electrically connected to the electrical apparatus. For transmitting electric power, the second connector  25  is electrically connected to the electrical apparatus. Meanwhile, the electrical apparatus delivers electric power to the battery module  26  through the transmission interface  24  for storing electric power.
