     DETAILED DESCRIPTION OF THE DISCLOSURE 
     The present disclosure will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements. 
       FIG. 1  is a block diagram of a smart collar according to an embodiment of the disclosure. Referring to  FIG. 1 , a smart collar  1  includes a main body  11  (not shown), a power module  12 , an image capturing module  13 , a sensing module  14 , a process-storage module  15 , and a wireless transmitting module  16 . The smart collar  1  is configured to detect a physical condition, a motion condition and an environment condition of a user for retrieving user condition data. The smart collar  1  can be made of fashion and elegant materials such as platinum, gold alloy, silver, gold or leather. When the user wears the smart collar  1 , the smart collar  1  can detect the physical condition, motion condition and environment condition of the user. 
     The main body  11  is a printed circuit board. To be noted, the conventional rigid printed circuit board has a rigid property, so it may restrict the size and design of the smart collar  1  and is not suitable for manufacturing the smart collar  1 . Preferably, the main body  11  is made of a flexible printed circuit board, so that the user can comfortably wear the smart collar  1 , and the smart collar  1  can fit the body of the user. In order to make the smart collar  1  have higher clock and better performance, the main body  11  can be cooperated with multilayer of printed circuit boards having more power layers and ground layers or an HDI (High Density Interconnection) printed circuit board. Accordingly, the main body  11  can have better electric properties, RF optimization and anti EMI ability. 
     The main body  11  can integrate other modules or components of the smart collar  1  such as the sensing module  14  and the sensors of the sensing module  14 , which are manufactured by MEMS (Microelectromechanical systems). In addition, the modules and the main body  11  can be integrated and disposed in the smart collar  1 . When the user wears the smart collar  1 , it can be bent to fit the shape of the human body, and the functions of the modules and components in the main body  11  are not affected. 
     The power module  12  includes a power control unit  121  and a battery  122 . The power control unit  121  controls the battery  122  to properly output the power to the modules according to the configuration of the modules. For example, the power control unit  121  can control the battery  122  to reduce the power supply to some modules. When the smart collar  1  is not connected to any device, the power supply to the wireless transmitting module can be reduced. When the smart collar  1  is in a standby mode, the power supply to the display module can be reduced. This configuration can improve the power capacity, use time and standby time of the smart ring  1 , and the user does not have to frequently charge the smart collar  1 . 
     Since the loading wire voltages and the power operation voltages of the modules in the main body  11  are different, the power control unit  121  further includes a specific DC/DC converter, such as the switching mode inductor-based DC/DC converter or the multitrack DC/DC converter with shared inductance. In order to increase the performance of the smart collar  1  and extend the lifetime of the battery  122 , the power control unit  121  may include a switching mode inductor-based DC/DC converter with inbuilt capacitance. Moreover, the battery  122  can be a thin lithium polymer battery, which has small volume and high electricity capacity. This kind of battery can occupy a small space inside the main body  11  and increase the power capacity of the smart collar  1 . 
     The image capturing module  13  can be an image sensor such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor) sensor. The image capturing module  13  is coupled to the power module  12  and retrieves at least one image data Di. The image data Di can be sent to a periphery device  2  via the wireless transmitting module  16 , and the periphery device  2  can display the image. The detailed description of the wireless transmitting module  16  will be discussed in the following. In other aspects, the smart collar  1  is connected to the periphery device  2  via a transmission line, and the image data Di is sent from the smart collar  1  to the periphery device  2  via the transmission line. This disclosure is not limited. 
     In addition, the image capturing module  13  may include an infrared image sensor for retrieving the image data Di. In this case, the retrieved image data Di includes the temperature image data or streaming temperature image data, so that the smart collar  1  can have the function of thermal image camera. Preferably, this image capturing module  13  can be used to record the thermal image of the fat burning status of the user when the user is doing exercise or workout. 
     In addition, the user may take off the smart collar  1  and use the image capturing module  13  to record the procedure and other information details in the exercise or sport of the user. Of course, the user can still wear the smart collar  1  for retrieving the thermal image of the environment. For example, it is possible to record the theiiiial image data of a group for the reference of preventing disease transmission. Besides, the image data Di can be provided to assist and guide the action of the user when the user is staying in a poor vision situation (e.g. in the night, dark, foggy or fire scene) and dangerous environment. Accordingly, the configuration of the image capturing module  13  can sufficiently improve the function of the smart collar  1 . 
     The sensing module  14  is coupled to the power module  12  and includes at least one sensor. In this embodiment, the sensing module  14  includes three sensors  141 ,  142  and  143 . Of course, in other embodiments, the sensing module  14  may include the sensors of different number, and this disclosure is not limited. 
     The sensor can detect at least one physical condition, at least one motion condition and at least one environment condition of the user so as to obtain physical condition data, motion condition data and environment condition data. For example, the sensor  141  can be an optical heart rate sensor or a reflective pulse oximeter for detecting the physical condition of the user, the sensor  142  can be a multi-axis gyroscope sensor, a multi-axis acceleration sensor, a geomagnetism sensor or an inertial sensor for detecting the motion condition of the user, and the sensor  143  can be a thermal sensor, an air pressure sensor, a humidity sensor, a pressure sensor, a height sensor, a light sensor or a gas sensor for detecting the environment condition of the user. Accordingly, the smart collar  1  can retrieve the physical condition data, motion condition data and environment condition data of the user by the sensors of the sensing module  14 . To make the drawings for clear, the sensing condition data Ds are shown in the figures to present the three condition data retrieved by the sensors  141 ,  142  and  143 . 
     The process-storage module  15  is coupled to the image capturing module  13  and the sensing module  14 , and includes at least a processing unit and at least a memory unit. In this embodiment, the process-storage module  15  includes a processing unit  151  and a memory unit  152 . Of course, in other embodiments, the process-storage module  15  may include multiple processing units and multiple memory units, and this disclosure is not limited. The processing unit  151  can be a CPU, a MPU, or controller. The memory unit  152  is coupled to the processing unit  151 , and the memory unit  152  can be a non-transitory computer readable storage medium such as a flash memory or SRAM. 
     The processing unit  151  generates the user condition data Du according to the physical condition data, the motion condition data and the environment condition data, which are retrieved by the sensors  141 ,  142  and  143 . The memory unit  152  stores the image data Di and the user condition data Du. The user condition data Du one or a combination of heart rate information, pulse information, Blood oxygen information, emotion information, sleep information, step information, distance information, caloric consumption information, body information, sitting time information, temperature information, air pressure information, humidity information, pressure information, height information, light information, and gas information. 
     The wireless transmitting module  16  receives the user condition data Du from the process-storage module  15 . In this embodiment, the smart collar  1  is communicated with a peripheral device  2  through the wireless transmitting module  16 , and the wireless transmitting module  16  can transmit the user condition data Du to the peripheral device  2 . The periphery device  2  can be a smart electronic device having the wireless transmission function (e.g. a smart phone, a tablet computer, a notebook computer, or a remote server). The wireless transmitting module  16  can be a low-power short-distance wireless transmission module such as a low-power Bluetooth module, a ZigBee module, an ANT+module, or a near field communication module. The wireless transmitting module  16  is communicated with the periphery device  2 , so that the smart collar  1  can transmit the data retrieved by the sensors to the periphery device  2 . Then, the periphery device  2  can perform a complex data analyzing and processing or a large amount of calculation. Thus, the smart collar  1  can be compact and light weight and have lower power consumption. Besides, the smart collar  1  can receive the related information and announcement from the periphery device  2  through the wireless transmitting module  16 . For example, the related information and announcement can be a text, a telephone call, the information of friends, or other information and data. 
     Similarly, the user condition data Du can be transmitted to the periphery device  2  through the wireless transmitting module  16  and then displayed by the periphery device  2 . In other aspects, the smart collar  1  is connected to the periphery device  2  via a transmission line, and the user condition data Du is sent from the smart collar  1  to the periphery device  2  for displaying via the transmission line. This disclosure is not limited. The user condition data Du may include any one or combination of the above-mentioned data, and this disclosure is not limited. 
     In the smart collar of this embodiment, the configuration of the power module can improve the power capacity, use time and standby time of the smart ring, and the user does not have to frequently charge the smart collar. In addition, the user may take off the smart collar and use the image capturing module to record the procedure and other information details in the exercise or sport of the user, or the user can still wear the smart collar for recording the procedure and other information details in the exercise or sport of the user. The configuration of the multiple sensors allows the smart collar to retrieve the detailed physical condition data, motion condition data and environment condition data of the user. The processing unit can generate the user condition data according to the physical condition data, the motion condition data and the environment condition data, which are retrieved by the sensors, and then the user condition data and the image data are stored in the memory unit. 
     Besides, the smart collar can transmit the image data and the user condition data to the periphery device through the wireless transmitting module. Moreover, the main body can integrate all modules and then disposed in the smart collar. When the user wears the smart collar, it can be bent to fit the shape of the human body, and the functions of the modules and components in the main body are not affected. 
       FIG. 2A  is a block diagram of a smart collar according to another embodiment of the disclosure,  FIG. 2B  is a schematic diagram of the smart collar of  FIG. 2A , which includes a display module, and  FIG. 2C  is a schematic diagram showing another aspect of the smart collar of  FIG. 2B , which includes a display module. 
     Referring to  FIGS. 2A and 2B , the smart collar  1   a  includes a main body  11 , a power module  12 , an image capturing module  13 , a sensing module  14 , a process-storage module  15 , and a wireless transmitting module  16 . The smart collar  1   a  further includes a display module  17 , which is disposed in the main body  11  and coupled to the power module  12  and the process-storage module  15 . 
     In this embodiment, the display module  17  is a lamp display module, which includes three indicators  171  for an example. The three indicators  171  can display different colors or the same color, and they can be properly arranged to indicate a plurality of different messages. In other aspects, the display module  171  may have different arrangement. For example, the display module  171  may have four or more indicators or have a display screen, and this disclosure is not limited. In this embodiment, the smart collar  1  can simply show the operation mode or multiple messages by the indicators  171 . Compared with other wearable devices having a display screen, the smart collar  1   a  does not need to frequently display the various user condition infoi nation. 
     In addition, the smart collar  1   a  can remind the user to perform the detection of a physical condition, a motion condition and an environment condition by the indicators. For example, the smart collar  1   a  can remind the user to perform an exercise by three blue indicators  171 . In practice, when the user sees that the three indicators  171  all emit blue light, he/she is reminded to start or prepare to do the exercise. In another case, the indicators  171  may flash the red light in a frequency, which matches the detected heart rate or heartbeat, so that the user can intuitionally observe his/her heart rate or heartbeat. In another case, the indicators  171  can show the residual power of the smart collar  1   a . For example, the indicator  171  emits green light when the residual power is over 80%, the indicator  171  emits orange light when the residual power is between 20% and 80%, and the indicator  171  flashes red light when the residual power is lower than 20%. In another case, when the smart collar  1   a  is performing an image capturing function or transmitting data to the periphery device  2 , the indicator  171  can emit a different color. 
     The display and arrangement of the indicators  171  can display the information of the smart collar  1   a , and decrease the power consumption speed of the smart collar  1   a  so as to increase the power capacity or extend the use time of the smart collar  1   a.    
     As shown in  FIG. 2C , the components and their relations of the smart collar  1   b  of  FIG. 2C  are the same as those of the smart collar  1   a . Different from the smart collar  1   a , the smart collar  1   b  includes a rotatable block and a non-rotatable block. The main body  11  and other components (including the image capturing module  13 ) disposed in the main body  11  within the rotatable block are isolated and rotatable with respect to other blocks. Accordingly, the image capturing module  13  can be rotated along with the main body  11  in different angles. In other words, when the user utilizes the record function or the camera function of the smart collar  1   b , the image capturing module  13  can be adjusted or rotated by the user to a desired angle for retrieving the images or screens in different angles. This configuration allows the smart collar  1   b  to have a wider viewing angle, so it can take the photo or image in front of the user and in other angles. 
     The other technical features of the smart collar  1   b  can be referred to the smart collar  1   a , so the detailed description thereof will be omitted. 
       FIG. 3A  is a schematic diagram of a smart collar  1   c  according to another embodiment of the disclosure. As shown in  FIG. 3A , the components and their relations of the smart collar  1   c  are mostly the same as those of the smart collar  1   a . Different from the smart collar  1   a , the smart collar  1   c  further includes a voice retrieving module  18  coupled to the power module  12  and the process-storage module  15 . The voice retrieving module  18  retrieves at least one voice data, and the storage unit  152  further stores the voice data. The voice retrieving module  18  is preferably an MEMS microphone. In this embodiment, the smart collar  1   c  includes one MEMS microphone. In other aspects, the smart collar  1   c  may include two or more MEMS microphones (e.g. 5 MEMS microphones). Besides, the ANC (Active Noise Cancellation) technology can be used to erase the undesired noise so as to improve the retrieved voice signal. When the user wears the smart collar and stays in a noise or crowd environment, the configuration of multiple MEMS microphones can help the voice retrieving module to retrieve the pour and clear voice data with good quality. 
     Accordingly, the smart collar  1   c  can retrieve the image data and the voice data by the image capturing module  13  in cooperated with the voice retrieving module  18 , so that the smart collar  1   c  can comprehensively record the procedure and other information details in the exercise or sport of the user. 
     Similarly, as shown in  FIG. 3B , the components and their relations of the smart collar  1   d  of  FIG. 3B  are the same as those of the smart collar  1   c . Different from the smart collar  1   c , the smart collar  1   d  includes a rotatable block and a non-rotatable block. The main body  11  and other components (including the image capturing module  13  and the voice retrieving module  18 ) disposed in the main body  11  within the rotatable block are isolated and rotatable with respect to other blocks. 
     Accordingly, the image capturing module  13  and the voice retrieving module  18  can be rotated along with the main body  11  in different angles with reference to other blocks. In other words, when the user utilizes the record function, the camera function or the voice retrieving function of the smart collar  1   d , the image capturing module  13  and the voice retrieving module  18  can be adjusted or rotated by the user to a desired angle for retrieving the images or screens in different angles. This configuration allows the smart collar  1   d  to have a wider viewing angle, so it can take the image or retrieve the voice in front of the user and in other angles. 
     The other technical features of the smart collar  1   d  can be referred to the smart collar  1   c , so the detailed description thereof will be omitted. 
       FIG. 4A  is a schematic diagram of a smart collar, which has a protection body, according to another embodiment of the disclosure, and  FIG. 4B  is a schematic diagram of the smart collar of  FIG. 4A  as the opening of the protection body is exposed. 
     As shown in  FIGS. 4A and 4B , the components of the smart collar  1   e  of  FIG. 3B  this embodiment are mostly the same as those of the smart collar  1   a . Different from smart collar  1   a , the main body  11  of the smart collar  1   e  is covered by a protection body  19 . In practice, the protection body  19  can be designed as the casing of the smart collar  1   e  or designed to directly contact with and fix to the user&#39;s body. In order to provide a comfortable wearing experience, the smart collar  1   e  should be fit to the user&#39;s body, and the material of the smart collar  1   e  is properly selected to prevent the undesired allergies and itches. For example, the material of the protection body  19  can be rubber or silica gel, so that the user can comfortably wear the smart collar. 
     In practice, the protection body  19  of  FIG. 4A  is an extendable elastic body. 
     In other words, the protection body  19  is made of extendable rubber or silica gel. The protection body  19  has an opening O, and the opening O is disposed outside the main body  11 . When the user opens the opening O of the extendable elastic body, the main body  11  is not exposed from the opening O. In addition, since the smart collar  1   e  is made of the extendable elastic rubber or silica gel, the smart collar  1   e  can flexibly fixed to the user&#39;s body or neck without the hook structure of the smart collar  1   a.    
     When the extendable elastic body is stretched, as shown in  FIG. 4B , the main body  11  is exposed from the extendable elastic body via the opening O, and one or a combination of the power module, the image capturing module, the sensing module and the process-storage module of the smart collar  1   e , which are disposed in the main body  11 , is adjusted to control the smart collar  1   e  to switch from a first configuration to a second configuration. To be noted, in this example, the power module  12  is exposed from the main body  11  via the opening O, so that the user can replace, increase or decrease the battery  122 . Similarly, in other aspects, another module can be exposed from the main body  11  via the opening O, so that the user can replace, increase or decrease the component in the exposed module. 
     In order to replace the battery  122 , the user can take the used battery with lower power or bad charging efficiency off, and then put on the new battery with higher power or normal charging efficiency. In other words, when the battery of the smart collar  1   e  is in a lower power status or has poor charging efficiency, the smart collar  1   e  is in a first configuration; when the battery of the smart collar  1   e  is in a high power status or has normal charging efficiency, the smart collar  1   e  is in a second configuration. 
     In order to increase the battery  122 , the user can increase the battery  122  of the smart collar  1   e  from one battery  122  to two batteries  122 . This configuration can increase the power capacity, use time and standby time of the smart collar  1   e . In this case, when the smart collar  1   e  has one battery  122 , the smart collar  1   e  is in a first configuration; when the smart collar  1   e  has two batteries  122 , the smart collar  1   e  is in a second configuration. 
     Accordingly, when the extendable elastic body is stretched, the opening can be exposed from the extendable elastic body, and then the user can adjust one or a combination of the power module, the image capturing module, the sensing module and the process-storage module to control the smart collar to switch from a first configuration to a second configuration. This operation can simply improve the function and expand the application of the smart collar. 
       FIG. 5  is a block diagram of a smart collar system according to an embodiment of the disclosure. As shown in  FIG. 5 , the smart collar system includes at least one periphery device and a smart collar. In this embodiment, the smart collar system  3  includes one smart collar  1  and two periphery devices  2 . Of course, in other embodiments, the smart collar  1  of the smart collar system  3  can be communicated with three or more periphery devices, and this disclosure is not limited. 
     Moreover, the smart collar  1  can be communicated with two periphery devices  2  via the wireless transmitting module  16 , and the wireless transmitting module  16  transmits the user condition data Du to the two peripheral devices  2 . This configuration can carry out the dual-directional data transmission between the smart collar  1  and the periphery devices  2 . The technical features of the smart collar  1  can be referred to the above embodiments, so the detailed description thereof will be omitted. 
     In summary, the smart collar of the disclosure is configured to detecting the physical condition, motion condition and environment condition of a user so as to retrieve the user condition data. The smart collar includes a main body, a power module, an image capturing module, a sensing module, a process-storage module, and a wireless transmitting module. Thus, the smart collar has good power capacity, use time and standby time, and the user does not need to recharge the smart collar frequently. Besides, the smart collar can record the detailed sport events and retrieve other information. 
     In addition, the smart collar of the disclosure can transmit the image data and user condition data to the peripheral device through the wireless transmitting module. Moreover, the main body can integrate with all modules, and the smart collar can be bent to fit the human body without affecting the functions of the modules. 
     Although the disclosure has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the disclosure.
