Description:
TECHNICAL FIELD 
       [0001]    At least one embodiment of the present invention provides a portable apparatus having detachable wireless elements. More particularly, at least one embodiment of the present invention provides a portable apparatus providing the ability to recharge, authenticate, and communicate wirelessly. 
       DESCRIPTION OF THE RELATED ART 
       [0002]    Mobile apparatuses such as smartphones and tablets are more popular and more available in recent years. Telephone calls and video conferences thus become more convenient. A significant portion of people with high demand of phone calls usually use accessories, such as Bluetooth headsets, with smartphones and tablets to accept incoming calls. 
         [0003]    However, the accessories are required to be paired with mobile apparatuses to initiate wireless communications and accept the incoming calls. More particularly, the accessories require PIN numbers to connect the mobile apparatuses. And each time to use the accessories, the accessories have to be manually switched on to connect to the wireless communication. Those steps to turn on, authenticate, and pair are complicated and less instinctive, thus impeding the convenience of using the accessories to have phone calls. 
         [0004]    Moreover, the embedded battery in accessories usually is rapidly depleted to empty. It usually requires a charger or cable specific to the accessories on hand and available sockets to recharge the accessories, which is inconvenient to the user. 
         [0005]    One foreseeable problem in conventional accessories is that if the accessories are running out of power during phone calls, the calls will be forced to end. Users usually have to manually transfer the call back to mobile apparatuses to continue the calls. 
         [0006]    Accordingly, there&#39;s a need for a mobile apparatus to mitigate the aforementioned inconvenience.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0018]      FIG. 1  is a schematic diagram illustrating a portable apparatus having detachable wireless elements, according to some embodiments of the present invention. As shown in  FIG. 1 , the portable apparatus having detachable wireless elements comprises a first device  1  and a second device  2 . The first device  1  may be a tablet, a smartphone, or a personal digital assistant (PDA), in which first device  1  is accessible by a mobile telecommunications network or internet. And the second device  2  may be a wireless headset, in which the second device  2  is accessible by a wireless network. The aforementioned wireless network may be a Bluetooth network, a WiFi network, or an infrared network. 
         [0019]    The second device  2  is accommodated in a dock  3  of the first device  1  under some situations, such as when the second device  2  is not in use. To accommodate the second device  2  in the dock  3 , the second device  2  is mounted to first device  1  by combining a second connector  21  on the second device  2  with the first connector  11  on the first device  1 . 
         [0020]    In the embodiments of  FIG. 1 , the first connector  11  is a female connector while the second connector  21  is a male connector. However, this configuration may be varied based on demands. For example, the first connector  11  may be a male connector or a female connector while the second connector  21  is a male connector or a female connector to be paired with the first connector  11 . 
         [0021]    Further details inside the first device  1  will be disclosed below. The first device  1  comprises a first connector  11 , two first rechargeable batteries  12 , a charger  13 , a first microprocessor  14 , a first wireless transceiver  15 , an acoustic pattern recorder  16 , a first battery management system  17 , a charging port  18 , and a pressure sensor  19 . 
         [0022]    More particularly, the first microprocessor  14  is connecting with the first connector  11 , the first wireless transceiver  15 , the acoustic pattern recorder  16 , the first battery management system  17 , and the pressure sensor  19  respectively. The two first rechargeable batteries  12  and the charger  13 , on the other hand, are connected to the first connector  11  and the first battery management system  17  respectively. And the charging port  18  is connecting with the first battery management system  17 . 
         [0023]    Further details inside the second device  2  will be disclosed below. The second device  2  comprises a second connector  21 , two second rechargeable batteries  22 , a second microprocessor  23 , a second battery management system  24 , an acoustic pattern recognition module  25 , a second wireless transceiver  26 , a memory module  27 , and an imaging sensor  28 . 
         [0024]    More particularly, the second connector  21 , the second battery management system  24 , the acoustic pattern recognition module  25 , the second wireless transceiver  26 , the memory module  27 , and the imaging sensor  28  are connecting with the second microprocessor  23  respectively. And the two second rechargeable batteries  22  are connecting with the second battery management system  24  while the second connector  21  is also connecting with the second battery management system  24 . 
         [0025]    Moreover, the first connector  11 , further comprising a first power module and a first information exchanger, is configured to engage with the second connector having a second power module and a second information exchanger. The physical connection between the first device  1  and the second device  2  provides channels to exchange information, such as battery levels, voice, and data. When the first connector  11  is connected to the second connector  21 , the first power module is also connected to the second power module, and the first information exchanger is connected to the second information exchanger. 
         [0026]    The first microprocessor  14  and the second microprocessor  23  each is the main processing unit of the first device  1  and the second device  2  respectively. The first microprocessor  14  and the second microprocessor  23  each may be a microcontroller unit (MCU) controlling the operations in the first device  1  and the second device  2  respectively. 
         [0027]    In the embodiments, the two first rechargeable batteries  12  are connected in series. Similar to the two first rechargeable batteries  12 , the two second rechargeable batteries  22  are also connected in series. The first rechargeable battery  12  and the second rechargeable battery  22  each is made of one selected from the group consisting of lithium iron phosphate, lithium ion, and lithium polymer. 
         [0028]    In the first device, the two first rechargeable batteries  12  comprise a first anode and a first cathode, while the charger comprises a second anode and a second cathode. The second cathode is connected to the first cathode. And the first anode and the second anode are electrically connected to the power module in the first connector  11  respectively, in which the connection provides a route to transmit power from the first rechargeable batteries  12  to the second device  2 . 
         [0029]    The first rechargeable battery  12  is configured in the first battery management system  17 , in which the first battery management system  17  is to manage the recharge-discharge process and to be as a battery protection board. In the embodiments, commands from first battery management system  17  are delivered via the first microprocessor  14 . The first battery management system  17  is connected to the charging port  18 , in which the charging port  18  is configured to receive power from an electric power system and transfer the power to the first rechargeable battery  12 . The charger  13 , on the other hand, is also connected with the first battery management system  17  and the power module in the first connector  11  respectively. The first device  1  is thus able to power the two second rechargeable batteries  22  in the second device  2  with the charger  13  and the stored power. 
         [0030]    Under some situations, such as when the second device  2  is not in use, the first connector  11  may be combined with the second connector  21 . While the first connector  11  and the second connector  21  are connected together, the first power module and the second power module recharge the second rechargeable battery  22 . And if the battery level of the second rechargeable battery  22  is below 75%, the second battery  22  is recharged with trickle charging. In contrast, when the battery level of the second battery  22  is lower than 25%, the second battery  22  is charged with higher electric current for fast charging. 
         [0031]    In some embodiments, the charging process induces the second microprocessor  23  to inactivate the second device  2 . More particularly, the charging process is coordinated by the first information exchanger and the second information exchanger to determine the charging conditions, such as to determine the use of trickle charging or fast charging. 
         [0032]    And if the physical connection between the first connector  11  and the second connector  21  is broken, the communication between the first information exchanger and the second information exchanger is thus disrupted, and this will automatically turn on wireless connection. 
         [0033]    The wireless connection is made between the first wireless transceiver  15  and the second wireless transceiver  26 . The first device  1  and the second device  2  are also able to be physically connected together. The first device  1  and the second device  2  do not require the pairing steps each time the wireless connection is turned on if the second device  2  has once physically and wirelessly paired to the first device  1 . 
         [0034]    The first wireless transceiver and the second wireless transceiver each is a Near Field Communication (NFC) transceiver, a WiFi transceiver, a Bluetooth transceiver, a 4G-LTE transceiver, or a Radio Frequency IDentification (RFID) transceiver. 
         [0035]    In some embodiments, the device further comprises a pressure sensor  19 . The pressure sensor  19  is connected to the first microprocessor  14  and is configured to detect the engagement between the second device  2  and the dock  3 . The pressure sensor  19  may be replaced by a NFC chips to detect the engagement in some other embodiments. 
         [0036]    In some embodiments, a user may detach the second device  2  from the first device  1  to accept an incoming call transmitted via a mobile telecommunications network or internet. Upon that the second device  2  is detached from the first device  1 , the connection between the first information exchanger and the second information exchanger is disrupted and thus turns on wireless connection. In some other embodiments, the reduced pressure to the pressure sensor  19  may also turns on the wireless connection. The acoustic pattern recorder  16  here is to transfer a registered acoustic data to the acoustic pattern recognition module  25  through the connection between the first wireless transceiver  15  and the second wireless transceiver  26 , in which the registered acoustic data may be an acoustic pattern or a password specific to a user. The connection is also used to pass the incoming call to the second device  2 . 
         [0037]    The acoustic pattern recognition module  25  in the second device  2  is to compare the user&#39;s voice and the registered acoustic data. If the user&#39;s voice matched the registered acoustic data, the second device  2  accepts the incoming call and thus allows the user to communicate under authenticated condition. 
         [0038]    In contrast, if the user&#39;s voice failed to match with the registered acoustic pattern or the acoustic pattern recognition module  25  is not in used for a period of time, the acoustic pattern recognition module  25  may leave a record of failure or idle. The record, no matter is based on failure or idle, is then transmitted to the first wireless transceiver  15  via the second wireless transceiver  26  to notify the first device  1  that the user and the registered data are unmatched. The first device  1  may also deny accepting the incoming call based on the record. 
         [0039]    In some embodiments, a call will be transferred back to the first device  1  if the battery level of the second device  2  is lower than 5% during a call, to ensure that the call will not be forced to stop. The switching process is coordinated by the second wireless transceiver  26  and the first wireless transceiver  15 . And a warning that the battery level of the second device  2  is nearly depleted to empty will be shown on the first device  1 . The user may then continue the call on the first device  1 . And the second device  2  may be rejoined to the first device  1  to be recharged. 
         [0040]    In some embodiments, the second device  2  further comprises a memory module  27  and that the second connector  21  is a male connector. The memory module  27  here may be any memory module known to the art. Under these embodiments, the second connector  21  may be used as a USB stick. 
         [0041]    In some embodiments, the second device  2  further comprises an imaging sensor  28  to capture images. The captured images are stored in the memory module  27  and then transferred to the first device  1  through the engagement between the first connector  11  and the second connector  21  or the aforementioned wireless connection. 
         [0042]      FIG. 2  is a schematic diagram illustrating a portable apparatus having detachable wireless elements, according to some other embodiments of the present invention. As shown in  FIG. 2 , part of the difference between the embodiments of  FIG. 1  and  FIG. 2  is that a fingerprint recorder  16 ′ and a fingerprint recognition module  25 ′ are used in  FIG. 2 . The fingerprint recorder  16 ′ here is to transfer a registered fingerprint, specific to a user, to the fingerprint recognition module  25 ′ through the connection between the first wireless transceiver  15  and the second wireless transceiver  26 . The connection is also used to pass the incoming call to the second device  2 . To accept an incoming call, the user may touch the fingerprint recognition module  25 ′, based on either capacitive fingerprinting or optical fingerprinting, on the second device  2  for authentication. 
         [0043]    Some embodiments of the present invention provide an advantage that an incoming call may be easily accepted by detaching the second device  2  from the first device  1 . Furthermore, some embodiments provide a secured mechanism to operate detachable elements. 
         [0044]    There are many inventions described and illustrated above. The present inventions are neither limited to any single aspect nor embodiment thereof, nor to any combinations and/or permutations of such aspects and/or embodiments. Moreover, each of the aspects of the present inventions, and/or embodiments thereof, may be employed alone or in combination with one or more of the other aspects of the present inventions and/or embodiments thereof. For the sake of brevity, many of those permutations and combinations will not be discussed separately herein.
