       2. Description of Related Art 
       [0002]    A cursor on a computer screen can be easily controlled by using a mouse, wherein the movement of the cursor on the screen corresponds to the displacement and the moving direction of the mouse. In recent years, the displacement and the moving direction of the mouse are detected by the optical mechanism instead of the traditional mechanical roller, which can increase the accuracy of mouse detection. As the technology develops, the wireless charging is being used in a mouse. Usually, to establish a connection between a wireless mouse and an electric device, a product serial number of the wireless mouse needs to be identified by a driving program. 
       SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0010]    Refer to  FIG. 1A  and  FIG. 2 .  FIG. 1A  shows a flow chart of a matching method for a wireless charging mouse of one embodiment of the instant disclosure, and  FIG. 2  shows a schematic diagram of a wireless charging mouse that is matching with an electric device in one embodiment of the instant disclosure. 
         [0011]    In step S 101 , the wireless charging mouse  205  determines whether a data transmission channel has been built. If yes, it goes to step S 102 . In step S 102 , the wireless charging mouse  205  and the electric device  215  transmit data according to a preset communication address. If no, it goes to step S 103 . In step S 103 , the wireless charging mouse  205  and the electric device  215  start to work in a matching mode. 
         [0012]    In step S 105 , the wireless charging mouse  205  receives electromagnetic energy generated by the charging board  210 . When a user puts the wireless charging mouse  205  close to the charging board  210 , a resonant coil (not shown) of the wireless charging mouse  205  and a resonant coil (not shown) of the charging board  210  are electromagnetically coupled, so that the wireless charging mouse  205  can receive the electromagnetic energy generated by the charging board  210 . After that, a converting circuit (not shown) of the wireless charging mouse  205  converts the electromagnetic energy to electric energy and provides the electric energy to a rechargeable battery (not shown) of the wireless charging mouse  205 . 
         [0013]    In step S 110 , the wireless charging mouse  205  builds a matching transmission channel according to the received electromagnetic energy for transmitting a first matching signal to the electric device. Specifically speaking, after the wireless charging mouse  205  receives the electromagnetic energy generated by the charging board  210 , a communication circuit (not shown) of the wireless charging mouse  205  is triggered by the electromagnetic energy to build a matching transmission channel at a matching address predetermined according to the electromagnetic energy. Through the matching transmission channel, the wireless charging mouse  205  transmits a first matching signal having a first RF transmission strength to the electric device  215 . The electric device  215  can be, for example, a laptop, a tablet, a personal computer or the like, and it is not limited herein. In addition, the wireless charging mouse  205  stores a plurality of matching addresses. After the wireless charging mouse  205  receives the electromagnetic energy, the communication circuit of the wireless charging mouse  205  is triggered to pick up one of the matching addresses for transmitting a first matching signal based on a first RF transmission strength to the electric device  215 . Different RF transmission strengths make the first matching signal transmit over different distances. After the wireless charging mouse  205  picks up one of the matching addresses and decides the RF transmission strength of the first matching signal, the first matching signal is transmitted to the electric device  215  by the wireless charging mouse  205 . 
         [0014]    In step S 115 , the electric device  215  determines whether the first matching signal has been received. If yes, it goes to step S 120 . If no, it returns to step S 110 . In the step S 110 , the electric device  215  keeps waiting for the first matching signal transmitted by the wireless charging mouse  205 . In other words, if the electric device  215  has not received the first matching signal transmitted by the wireless charging mouse  205 , the wireless charging mouse  205  transmits the first matching signal to the electric device  215  again. 
         [0015]    In step S 120 , the electric device  215  transmits a first response signal to the wireless charging mouse  205  through the matching transmission channel. Specifically speaking, after the electric device  215  receives the first matching signal transmitted based on the first RF transmission strength by the wireless charging mouse  205  through the matching transmission channel, the electric device  215  transmits a first response signal based on a second RF transmission strength to the wireless charging mouse  205  through the matching transmission channel and also generates a first communication address. The electric device  215  stores the first communication address in a first-in-first-out register. 
         [0016]    In step S 125 , the wireless charging mouse  205  determines whether the first response signal has been received. If yes, it goes to step S 130 . If no, it returns to step S 120 . In step S 120 , the wireless charging mouse  205  keeps waiting for the first response signal transmitted by the electric device  215 . In other words, if the wireless charging mouse  205  has not received the first response signal transmitted by the electric device  215 , the electric device  215  transmits the first response signal to the wireless charging mouse  205  again. 
         [0017]    In step S 130 , the wireless charging mouse  205  again transmits the first matching signal to the electric device  215 . Specifically speaking, after the wireless charging mouse  205  has received the first response signal transmitted by the electric device  215 , the wireless charging mouse  205  again transmits the first matching signal based on the first RF transmission strength to the electric device  215  through the matching transmission channel. 
         [0018]    In step S 135 , the electric device  215  determines whether the first matching signal has again been received. If yes, it goes to step S 140 . If no, it returns to step S 130 . In step S 130 , the electric device  215  keeps waiting for the first matching signal to again be transmitted by the wireless charging mouse  205 . It should be noted that, if the electric device  215  does not again receive the first matching signal transmitted by the wireless charging mouse  205 , it may be the result of an insufficient power supply, communication interferences or other factors. 
         [0019]    In step S 140 , the electric device  215  transmits a second response signal to the wireless charging mouse  205 . Specifically speaking, after the electric device  215  again has received the first matching signal transmitted by the wireless charging mouse  205 , the electric device  215  is triggered to generate a second response signal. The electric device  215  transmits the second response signal based on a second RF transmission strength to the wireless charging mouse  205  through the matching transmission channel. In the meantime, the electric device  215  transmits the first communication address stored in the first-in-first-out register to the wireless charging mouse  205 . 
         [0020]    In step S 145 , the electric device  215  and the wireless charging mouse  205  enter a data transmission mode. Specifically speaking, after the wireless charging mouse  205  has received the second response signal transmitted by the electric device  215 , the wireless charging mouse  205  stores the first communication address and builds a first transmission channel at the first communication address. After that, the electric device  215  and the wireless charging mouse  205  enter a data transmission mode. In other words, they start to transmit data through the first transmission channel built at the first communication address. In addition, the wireless charging mouse  205  can have an indicator lamp (not shown). When the wireless charging mouse  205  works in the matching mode, the indicator lamp flashes; for example, it flashes and emits the red light. After the electric device  215  and the wireless charging mouse  205  enter the data transmission mode, the indicator lamp emits the green light to indicate that the wireless connection is working well. However, it is not limited herein. In addition, the wireless charging mouse  205  can also have a reset button (not shown). After a user has pushed the reset button for 3 seconds, the wireless charging mouse  205  automatically deletes the first communication address previously picked and the first transmission channel that has been built, to save the memory of the wireless charging mouse  205  for data storage. 
         [0021]    Refer to  FIG. 1B  and  FIG. 2 .  FIG. 1B  shows a flow chart of a matching method for a wireless charging mouse of another embodiment of the instant disclosure. The difference between the matching methods shown in  FIG. 1A  and  FIG. 1B  is that there is a step S 128  added in the matching method shown in  FIG. 1B . Except for step S 128 , the steps of the matching method shown in  FIG. 1A  and  FIG. 1B  are the same. After the wireless charging mouse  205  receives the first response signal transmitted by the electric device  215 , it goes to step S 128 . In step S 128 , the electric device  215  determines whether to continually receive the electromagnetic energy generated by the charging board  210 . If yes, it goes to step S 130 . If no, it returns to step S 105 . In step S 105 , the wireless charging mouse  205  keeps waiting to receive electromagnetic energy generated by the charging board  210 . 
         [0022]    Refer to  FIG. 2 ,  FIG. 3A  and  FIG. 3B .  FIG. 3A  and  FIG. 3B  show flow charts of a matching method for a wireless charging mouse of another embodiment of the instant disclosure. Compared with the matching methods shown in  FIG. 1A  and  FIG. 1B , in the matching methods shown in  FIG. 3A  and  FIG. 3B , the magnitude of the received electromagnetic energy and the time for receiving the electromagnetic energy are taken into account. Steps S 301 ˜S 305  correspond to steps S 101 ˜S 105 . 
         [0023]    In step S 307 , if the wireless charging mouse  205  determines that the electromagnetic energy generated by the charging board  210  is higher than a predetermined electromagnetic energy, it goes to step S 309 . If the wireless charging mouse  205  determines that the electromagnetic energy generated by the charging board  210  is lower than the predetermined electromagnetic energy, it returns to step S 305 . In step S 305 , the wireless charging mouse  205  keeps waiting to receive electromagnetic energy generated by the charging board  210 , and waiting for the received electromagnetic energy generated by the charging board  210  to be higher than the predetermined electromagnetic energy. It should be easily understood by those skilled in the art that, the energy magnitude of the electromagnetic energy is inversely proportional to the transmission distance of the electromagnetic energy. In other words, the closer one is to an electromagnetic energy source, the higher the electromagnetic energy that one can receive will be. On the contrary, the more distant one is from an electromagnetic energy source, the lower the electromagnetic energy that one can receive will be. Thus, by determining the magnitude of the electromagnetic energy received by the wireless charging mouse  205 , it can be known whether the wireless charging mouse  205  has been put on the charging board  210  or is close to the charging board  210 . For example, the wireless charging mouse  205  may be only 3 cm from to the charging board  210 . 
         [0024]    In step S 309 , if the wireless charging mouse  205  determines that the electromagnetic energy received by the wireless charging mouse  205  has been lower than the predetermined electromagnetic energy over a predetermined time, it goes to step S 310 . If the wireless charging mouse  205  determines that the electromagnetic energy received by the wireless charging mouse  205  has not been lower than the predetermined electromagnetic energy over the predetermined time, it returns to step S 305 . In step S 305 , the wireless charging mouse  205  keeps waiting to again receive electromagnetic energy generated by the charging board  210 . In step S 309 , the wireless charging mouse  205  is triggered to build a matching transmission channel, after it is determined that the wireless charging mouse  205  has been put onto or close to the charging board  210  over the predetermined time. Thus, if the wireless charging mouse  205  is moved by a user only for a short while, the wireless charging mouse  205  will not try to start a matching mode with the electric device  215 , which is power-saving. It should be noted that steps S 310 ˜S 345  correspond to steps S 101 ˜S 145 . 
         [0025]    In step S 350 , the wireless charging mouse  205  determines whether the received electromagnetic energy is lower than the predetermined electromagnetic energy. Specifically speaking, if the received electromagnetic energy generated by the charging board  210  is lower than the predetermined electromagnetic energy, it goes to step S 355 . If the received electromagnetic energy from the charging board  210  is higher than the predetermined electromagnetic energy, it returns to step S 345 . In step S 345 , the wireless charging mouse  205  and the electric device  215  keeps working in the data transmission mode. 
         [0026]    In step S 355 , the wireless charging mouse  205  determines whether the received electromagnetic energy generated by the charging board  210  has been lower than the predetermined electromagnetic energy for a predetermined time. If yes, it goes to step S 360 . In step S 360 , the wireless charging mouse  205  and the electric device  215  end the data transmission mode. If no, it returns to step S 345 . In step S 345 , the wireless charging mouse  205  and the electric device  215  keeps working in the data transmission mode. Step S 355  prevents the wireless charging mouse  205  and the electric device  215  from ending the data transmission mode because a user inadvertently moves the wireless charging mouse  205  only for a short time. 
         [0027]    Refer to  FIG. 2 ,  FIG. 4A  and  FIG. 4B .  FIG. 4A  and  FIG. 4B  show flow charts of a matching method for a wireless charging mouse of still another embodiment of the instant disclosure. It should be noted that, steps S 401 ˜S 420  correspond to steps S 101 ˜S 120 . 
         [0028]    In step S 425 , the wireless charging mouse  205  determines whether a first response signal is received. Specifically speaking, if the wireless charging mouse  205  receives the first response signal transmitted by the electric device  215 , it goes to step S 428 . If the wireless charging mouse  205  has not received the first response signal transmitted by the electric device  215 , it returns to step S 426 . 
         [0029]    In step S 426 , the wireless charging mouse  205  determines whether the times of transmitting the first matching signal by the wireless charging mouse  205  equals to an upper bound. If the times of transmitting the first matching signal by the wireless charging mouse  205  have not yet been equal to the upper bound, it returns to step S 410 . In step S 410 , the wireless charging mouse  205  again transmits a first matching signal to the electric device  215 . On the other hand, if the times of transmitting the first matching signal by the wireless charging mouse  205  are equal to the upper bound, the wireless charging mouse  205  temporarily stops transmitting the first matching signal to the electric device  215 , and it goes to step S 427 . In step S 427 , the wireless charging mouse  205  changes the matching address. After that, it goes to step S 405 . In step S 405 , the wireless charging mouse  205  waits to be triggered by electromagnetic energy generated by the charging board  210 . 
         [0030]    In step S 428 , the wireless charging mouse  205  determines whether to continually receive the electromagnetic energy generated by the charging board  210 . If yes, it goes to step S 430 . If no, it returns to step S 405 . In step S 405 , the wireless charging mouse  205  keeps waiting to receive electromagnetic energy generated by the charging board  210 . 
         [0031]    In step S 430 , the wireless charging mouse  205  again transmits the first matching signal to the electric device  215 . In step S 435 , the electric device  215  determines whether the first matching signal has again been received. If yes, it goes to step S 436 . If no, it returns to step S 430 . In step S 430 , the wireless charging mouse  205  again transmits a first matching signal to the electric device  215 . 
         [0032]    In step S 436 , the electric device  215  determines whether the first matching signal has been entirely received. If yes, it goes to step S 437 . If no, it returns to step S 430 , and in step S 430 , the wireless charging mouse  205  again transmits a first matching signal to the electric device  215 . In addition, the electric device  215  can comprise a communication circuit, to check whether the first matching signal has been entirely received by the wireless charging mouse  205 . 
         [0033]    In step S 437 , the electric device  215  determines whether the first matching signal has been transmitted from the matching address in the matching transmission channel. If yes, it goes to step S 438 . If no, it returns to step S 430 . In step S 430 , the wireless charging mouse  205  again transmits a first matching signal to the electric device  215 . If the electric device  215  determines that the first matching signal has been transmitted from the matching address in the matching transmission channel, it indicates that the electric device  215  has again received the first matching signal. 
         [0034]    In step S 438 , the electric device  215  prepares a reply packet and stores the reply packet in its first-in-first-out register. Specifically speaking, when the electric device  215  again receives the first matching signal, the electric device  215  prepares a reply packet and stores the reply packet in its first-in-first-out register, wherein the reply packet comprises the first communication address. The first-in-first-out register of the electric device  215  can be implemented by any electric element having data storage function, and it is not limited herein. 
         [0035]    In step S 440 , the electric device  215  transmits a second response signal to the wireless charging mouse  205 . In step S 441 , the wireless charging mouse  205  determines whether the second response signal has been entirely received. If yes, it goes to step S 442 . If no, it returns to step S 440 , and in step S 440 , the electric device  215  again transmits a second response signal to the wireless charging mouse  205 . 
         [0036]    In step S 442 , the wireless charging mouse  205  receives the reply packet transmitted by the electric device  215 . Specifically speaking, when the second response signal has been entirely received by the wireless charging mouse  205 , the wireless charging mouse  205  also receives the reply packet previously stored in the first-in-first-out register of the electric device  215 . 
         [0037]    In step S 443 , the wireless charging mouse  205  builds a first transmission channel according to the reply packet. Specifically speaking, after the wireless charging mouse  205  receives the reply packet, the wireless charging mouse  205  obtains the first communication address from the reply packet. The wireless charging mouse  205  stores the first communication address and builds a first transmission channel at the first communication address. In step S 445 , the wireless charging mouse  205  and the electric device  215  start to work in the data transmission mode. When the wireless charging mouse  205  and the electric device  215  are working in the data transmission mode, the wireless charging mouse  205  transmits a data signal from the first communication address based on a third RF transmission strength to the electric device  215 . On the other hand, the electric device  215  transmits another data signal from the first communication address based on a fourth RF transmission strength to the wireless charging mouse  205 . It should be noticed that, the third RF transmission strength is larger than the first RF transmission strength, and the fourth RF transmission strength is larger than the second RF transmission strength. In detail, the first RF transmission strength is the smallest RF transmission strength based on which the wireless charging mouse  205  transmits signals, and the third transmission strength is the largest RF transmission strength based on which the wireless charging mouse  205  transmits signals. The second RF transmission strength is the smallest RF transmission strength based on which the electric device  215  transmits signals, and the fourth transmission strength is the largest RF transmission strength based on which the electric device  215  transmits signals. When the wireless charging mouse  205  and the electric device  215  are working in the matching mode, they need to be closer to each other to prevent signal interference between the wireless charging mouse  205  and other electric products. When the wireless charging mouse  205  and the electric device  215  are working in the data transmission mode, a user can use the wireless charging mouse  205  within a certain range of distance as long as signals can be effectively transmitted between the wireless charging mouse  205  and the electric device  215 . 
         [0038]    To sum up, in the matching method of a wireless charging mouse provided by the instant disclosure, the wireless charging mouse can be triggered by an electromagnetic energy generated by the charging board to build a transmission channel After that, by the matching signal and the response signal it can be determined whether the wireless charging mouse and the electric device have started to work in a data transmission mode. By this matching method, even when the wireless charging mouse is put on a charging board for charging for a very short time, the wireless charging mouse and electric device can quickly be wirelessly connected without installing and setting a driving program.

All changes, alterations, or modifications conveniently considered by those skilled in the art are deemed to be encompassed within the scope of the instant disclosure delineated by the following claims.
