DETAILED DESCRIPTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purposes only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

As used herein, the expression “have”, “may have”, “include”, or “may include” refers to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element such as component), and does not exclude one or more additional features.

In the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.

The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposer between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no element (e.g., third element) interposed between them.

The expression “configured to” used in the present disclosure may be exchanged with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g. embedded processor) for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

The terms used in the present disclosure are only used to describe specific embodiments of the present disclosure, and are not intended to limit the present disclosure. As used herein, singular forms may include plural forms as well unless the context clearly indicates otherwise. Unless defined otherwise, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by a person skilled in the art to which the present disclosure pertains. Such terms as those defined in a generally used dictionary may be interpreted to have the meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present disclosure. In some cases, even the term defined in the present disclosure should not be interpreted to exclude various embodiments of the present disclosure.

FIG. 1 is a block diagram illustrating a network environment including therein an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 1, a network environment 100 may include an electronic device 101 to perform communications. The electronic device 101 may include, but not limited to, a bus 110, a processor 120, a memory 130, an input/output interface 150, a display 160, a communication interface 170, and a connection control module 180.

In various embodiments of the present disclosure, at least one of the elements of the electronic device 101 may be omitted or other elements may be additionally included in the electronic device 101.

The bus 110 may include, for example, a circuit which interconnects the elements 110 to 180 and provides communication (e.g., a control message and/or data) between the elements 110 to 180.

The processor 120 may include one or more of a CPU, an AP, and a communication processor (CP). The processor 120, for example, may carry out operations or data processing relating to control and/or communication of at least one element of the electronic device 101.

The memory 130 may include a volatile memory and/or a non-volatile memory. The memory 130 may store, for example, instructions or data relevant to at least one element of the electronic device 101. According to an embodiment of the present disclosure, the memory 130 may store software and/or a program 140. The program 140 may include, for example, a kernel 141, middleware 143, an application programming interface (API) 145, and/or applications 147. At least some of the kernel 141, the middleware 143, and the API 145 may be referred to as an operating system (OS).

The kernel 141 may control or manage system resources (for example, the bus 110, the processor 120, or the memory 130) used for executing an operation or function implemented by other programs (for example, the middleware 143, the API 145, or the applications 147). Furthermore, the kernel 141 may provide an interface through which the middleware 143, the API 145, or the applications 147 may access the individual elements of the electronic device 101 to control or manage the system resources.

The middleware 143 may perform intermediation by which the API 145 or the applications 147 communicates with the kernel 141 to transmit or receive data. In addition, the middleware 143 may process one or more task requests received from the applications 147 according to priorities thereof. For example, the middleware 143 may assign a priority, which enables the use of system resources (e.g., the bus 110, the processor 120, the memory 130, etc.) of the electronic device 101, to at least one of the applications 147. For example, the middleware 143 may perform scheduling or loading balancing on the one or more task requests by processing the one or more task requests according to the priorities assigned thereto.

The API 145 is an interface for allowing the applications 147 to control a function provided by the kernel 141 or the middleware 143 and may include, for example, at least one interface or function (e.g., a command) for file control, window control, image processing, text control, and the like.

The input/output interface 150, for example, may transfer instructions or data input from a user or another external device to the other element(s) of the electronic device 101. Furthermore, the input/output interface 150 may output the instructions or data received from the other element(s) of the electronic device 101 to the user or another external device.

The display 160 may include, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a micro electro mechanical system (MEMS) display, or an electronic paper display. For example, the display 160 may display various pieces of content (e.g., text, images, videos, icons, symbols, etc.) to the user. The display 160 may include a touch screen, and for example, receive a touch, gesture, proximity, or hovering input using an electronic pen or a body part of a user.

The communication interface 170, for example, may enable communication between the electronic device 101 and an external device (e.g., the first external electronic device 102, the second external electronic device 104, or a server 106). For example, the communication interface 170 may be connected to a network 162 through wireless or wired communication to communicate with the external device (e.g., the second external electronic device 104 or the server 106).

The wireless communication may use at least one of, for example, long term evolution (LTE), LTE-advanced (LTE-A), code division multiple access (CDMA), wideband CDMA (WCDMA), universal mobile telecommunications system (UMTS), wireless broadband (WiBro), and global system for mobile communications (GSM), as a cellular communication protocol. In addition, the wireless communication may include, for example, short range communication 164. The short-range communication 164 may include at least one of, for example, wireless fidelity (WiFi), Bluetooth® (BT), near field communication (NFC), and GPS. The wired communication may include at least one of, for example, a universal serial bus (USB), a high definition multimedia interface (HDMI), recommended standard 232 (RS-232), and a plain old telephone service (POTS). The network 162 may include at least one of communication networks, such as a computer network (e.g., a local area network (LAN), or a wide area network (WAN)), the Internet, and a telephone network.

The connection control module 180 may control some functions of the electronic device 101, for example, by using the processor 120 or independently of the processor 120 such that the electronic device 101 interworks with another electronic device. The other electronic device may be, for example, the first external electronic device 102, the second external electronic device 104, or the server 106. In addition, for example, the other electronic device may include a processor and a display that operate independently of the processor 120 of the electronic device 101, and may be a peripheral device or accessory that can be attached to or detached from the electronic device 101. The other electronic device may be a part of the electronic device 101 that can be detached from the electronic device 101.

According to an embodiment of the present disclosure, the connection control module 180 may selectively provide content when it is determined that there will be a change in the connection state between the electronic device 101 and the other electronic device. The connection control module 180 may change a supply source of content provided through the electronic device 101, for example, in response to the attachment or detachment between the electronic device 101 and the other electronic device. According to an embodiment of the present disclosure, the connection control module 180 may perform a control associated with the electric power of the electronic device 101 or the other electronic device in response to the attachment or detachment.

Although the connection control module 180 is illustrated to be independent of the processor 120 and the memory 130 in FIG. 1, various embodiments of the present disclosure are not limited thereto. At least a part of the connection control module 180, for example, may be integrated with the processor 120, or may be executed in the processor 120 while being stored in a software form in the memory 130. Further, at least a part of the connection control module 180, for example, may be distributed in the processor 120 and the memory 130. Alternatively, other various embodiments of the present disclosure can be made.

Each of the first and second external electronic devices 102 and 104 may be identical to or different from that of the electronic device 101. According to an embodiment of the present disclosure, the server 106 may include a group of one or more servers. According to various embodiments of the present disclosure, all or some of the operations performed in the electronic device 101 may be performed in another electronic device or a plurality of electronic devices (e.g., the electronic devices 102 and 104 or the server 106). According to an embodiment of the present disclosure, when the electronic device 101 has to perform some functions or services automatically or in response to a request, the electronic device 101 may request to perform at least some functions relating thereto to another device (e.g., the electronic device 102 or 104 or the server 106) instead of performing the functions or services by itself or additionally. The other electronic device (e.g., the electronic device 102 or 104 or the server 106) may carry out the requested functions or the additional functions and transfer the result to the electronic device 101. The electronic device 101 may process the received result as it is or additionally to provide the requested functions or services. To achieve this, for example, cloud computing, distributed computing, or client-server computing technology may be used.

FIG. 2 is a block diagram of a connection control module of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 2, a connection control module 201 may be an implementation of the connection control module 180 for use in an electronic device 101. The connection control module 201 may include a detection module 210, a determination module 220, a change module 230, and a provision module 240. Herein, an embodiment of the present disclosure in which the connection control module is distinguished into specific modules is described for convenience of description. However, various embodiments of the present disclosure are not limited thereto and may include various hardware/software structures that can realize substantially similar operations. For example, at least some of the modules according to this embodiment of the present disclosure may be omitted, or a specific module may also perform the function of another module instead.

The detection module 210 may acquire, for example, information associated with a physical connection with an external device (e.g., the first or second external electronic device 102 or 104). According to an embodiment of the present disclosure, when the electronic device is physically or electrically coupled to or separated from the external device, the detection module 210 may detect a change in a signal generated by the electronic device or a connector of the external device. For example, the detection module 210 may detect an analog or digital signal generated by a part of the connector. The connector may include, for example, a contact terminal, a magnet, a pin, a locking device, or the like. For example, the detection module may detect a signal generated when at least one of a plurality of contact terminals (or contact points) is separated from the corresponding contact terminal of the external device. According to an embodiment of the present disclosure, the detection module 210 may detect a change in a signal generated from a sensor (e.g., a touch sensor) that is formed on at least a part of a housing or screen of the electronic device.

The determination module 220 may determine that there will be a change in a connection state between the electronic device and the external device, for example, based on an event occurring in at least one of the electronic device and the external device. According to an embodiment of the present disclosure, based on information received from the detection module 210, the determination module 220 may determine that the electronic device is to be detached from the external device, or may determine that the electronic device is to be mounted on the external device.

According to an embodiment of the present disclosure, when a change of signal that is generated by a contact point of the electronic device satisfies a specified condition while the electronic device is mounted on the external device, the determination module 220 may determine that the electronic device is to be detached from the external device. The specified condition may include, for example, the order, amount, difference, or interval of the signal change. Additional information associated with the determination of detachment on the basis of the signal change that has occurred in regard to the plurality of contact points of the electronic device 200 is provided below in connection with FIG. 3B.

According to an embodiment of the present disclosure, when a user's grip satisfies a specified condition while the electronic device is mounted on the external device, the determination module 220 may determine that the electronic device is to be detached from the external device, or may determine that the electronic device is to be mounted on the external device. The specified condition may include, for example, the order, area, pressure, or interval of grips recognized by the electronic device and the external device. Information associated with the grip may be detected, for example, through a touch sensor (e.g., a touch panel). According to an embodiment of the present disclosure, when a grip recognized by the external device satisfies a specified condition while the external device is mounted on the electronic device, the external device may transfer information associated with the recognized grip to the electronic device.

For example, when one hand of a user is detected in a specified area of the touch sensor of the electronic device, and the other hand of the user is detected in the specified area of the touch sensor of the external device within a specified time (e.g., five seconds), the determination module 220 may determine that the electronic device is to be detached from the external device. In addition, for example, when at least one hand of a user is detected in the specified area of the touch sensor of the electronic device, and the electronic device is within a specified distance (e.g., about 10 cm) from the external device, the determination module 220 may determine that the electronic device is to be mounted on the external device. The distance from the external device may be determined, for example, based on a quality (e.g., intensity) of a signal received from the external device.

According to an embodiment of the present disclosure, a change in the connection state between the electronic device and the external device may be determined based on the type of an application executed in the electronic device or the external device. For example, when user authentication is performed through the electronic device while a payment application is being executed in the external device, the determination module 220 may predict that the electronic device is to be detached from the external device. According to an embodiment of the present disclosure, the determination module 220 may represent (e.g., display) that a service associated with the detachment can be performed. According to an embodiment of the present disclosure, a change in the connection state between the electronic device and the external device may also be determined based on an access point where the two devices are connected to each other, the locations of the two devices, a received message, or the like.

According to an embodiment of the present disclosure, the determination module 220 may use information that is received from the external device as at least a part of the event. For example, while the external device is mounted on the electronic device, when a change of signals generated from at least some of the contact points of the external device satisfies a specified condition, the external device may transmit information to the electronic device. The electronic device may determine (recognize) that the electronic device is already detached from the external device by using the received information. According to an embodiment of the present disclosure, the external device may determine (predict) that the electronic device and the external device are to be physically or electrically separated from each other, and may transfer information containing the determination result to the electronic device.

According to an embodiment of the present disclosure, before a specified time passes from when it is determined that there will be a change in the connection state between the electronic device and the external device, the determination module 220 may identify whether the change (e.g., detachment or mounting) occurs. Herein, for convenience of description, the time point of the determination is referred to as a prediction time point, and the information containing the determination result is referred to as prediction information. According to an embodiment of the present disclosure, when a signal to indicate detachment is received from the detection module 210 (or connector) within a specified time (e.g., three seconds) from the prediction time point, the determination module 220 may identify that the electronic device has been detached from the external device. For example, the specified time may vary according to the type of an application executed in the electronic device or the external device. In addition, for example, the specified time may also vary according to the order, area, pressure, or interval of grips detected by the electronic device or the external device. According to an embodiment of the present disclosure, the specified time may also be set to a different time according to the connection structure of the electronic device and the external device. For example, when there is an additional locking structure for assisting the physical coupling between the electronic device and the external device, the specified time may be set based on time (e.g., 20 seconds) for an operation of the locking structure.

According to an embodiment of the present disclosure, if a signal to indicate detachment is not received from the detection module 210 within a specified time from the prediction time point, the determination module 220 may determine that the physical coupling between the electronic device and the external device is maintained. For example, if the electronic device is not detached from the external device within a specified time from the prediction time point, the determination module 220 may stop identifying the change.

The change module 230 may control a processor, power, or communication of the electronic device when it is determined that the electronic device is to be mounted on the external device, or is to be detached from the external device. According to an embodiment of the present disclosure, the change module 230 may change at least one processor included in the electronic device to an activated state or a deactivated state. For example, when the change module 230 determines that there will be a change in the connection state between the electronic device and the external device, the change module may change a processor (e.g., an AP) that is external to the connection control module 201 from a deactivated state to an activated state. The deactivated state may include, for example, a power off state or a power saving mode (e.g., a sleep mode).

For example, when the determination module 220 determines that there will be a change in the connection state between the electronic device and the external device, the change module 230 may allow at least some elements of the electronic device to receive power from a power supply source (e.g., a battery) included in the electronic device. For example, when it is recognized that the electronic device is already detached from the external device, or when it is predicted that the electronic device is to be detached from the external device, the change module 230 may change the power supply source from an external supply source to an internal supply source. According to an embodiment of the present disclosure, when it is recognized that the electronic device is already detached from the external device, or when it is predicted that the electronic device is to be detached from the external device, the change module 230 may also change the power supply source from an internal supply source to an external supply source.

According to an embodiment of the present disclosure, when it is recognized that the electronic device is already detached from the external device, or it is predicted that the electronic device is to be detached from the external device, and the residual power of the power supply source included in the electronic device is lower than or equal to a specified reference (e.g., about 30% of a battery capacity), the change module 230 may change the operating mode of the electronic device to a low-power mode. The low-power mode may include, for example, a change of display setting (e.g., color, brightness, etc.), a change of a processor operating frequency, a change of a communication means, termination of a running application, or the like. According to an embodiment of the present disclosure, when it is recognized that the electronic device is already detached from the external device, or it is predicted that the electronic device is to be detached from the external device, and the residual power of the power supply source included in the electronic device is lower than or equal to a specified reference (e.g., about 30% of a battery capacity), the external device may wirelessly transfer power to the electronic device. In cases where the electronic device can wirelessly receive power from the external device, the electronic device may not change the operating mode thereof to the low-power mode.

According to an embodiment of the present disclosure, when it is recognized that the electronic device is already detached from the external device, or when it is predicted that the electronic device is to be detached from the external device, the change module 230 may activate a specific function, for example, a wireless charging function that corresponds the low-power mode of the electronic device. For example, when the residual power of the power supply source included in the electronic device is lower than or equal to a specified reference (e.g., about 50% of a battery capacity), the change module 230 may wirelessly receive power from the external device or another external wireless power supply source (e.g., a wireless charging pad).

The provision module 240, for example, may display data received from the external device through an output device (e.g., the display 160) of the electronic device while mounted on the external device. According to an embodiment of the present disclosure, the received data may also be directly transferred to the output device without the provision module 240.

According to an embodiment of the present disclosure, the provision module 240 may store data received from the external device in a memory (e.g., the memory 130). For example, when the electronic device is predicted to be detached from the external device, the provision module 240 may display a screen using the data stored in the memory and then may stop receiving data from the external device. According to an embodiment of the present disclosure, the provision module 240 may output the data stored in the memory for a specified time, and may output, for example, data received from a server through a communication interface (e.g., the communication interface 170) after the specified time.

For example, when it is determined that the electronic device is already detached from the external device, or when it is predicted that the electronic device is to be detached from the external device, the provision module 240 may execute a specified application. For example, in regard to an application executed in the external device, the provision module 240 may provide content provided before the prediction, or another piece of content associated with the application. According to an embodiment of the present disclosure, the provision module 240 may execute an application that can access and manipulate data received from the external device. For example, while the electronic device receives, from the external device, data associated with a telephone application executed in the external device and displays the received data through the display of the electronic device while mounted on the external device, when it is determined that the electronic device is already detached from the external device, or when the electronic device is estimated to be detached from the external device, the electronic device may execute a memo application to manipulate the data received from the external device in the electronic device.

In cases where the electronic device is spaced a specified distance or more from the external device, the provision module 240 may stop providing data through the electronic device. According to an embodiment of the present disclosure, while the electronic device is mounted on the external device, when a specified application is executed in the external device, and thereafter the electronic device is detached from the external device, the electronic device may allow an input/output device to be used within a specified distance range. For example, when the electronic device is spaced away from the external device by a specified distance (e.g., five meters) or more while performing a payment (e.g., financial payment) function, the electronic device may stop the payment function. According to an embodiment of the present disclosure, in cases where the electronic device is spaced away from the external device by a specified distance, the provision module 240 may change the electronic device to a locked state, or may deactivate (e.g., turn off) the screen of the electronic device.

According to an embodiment of the present disclosure, when a specified time passes after the electronic device is separated from the external device, the provision module 240 may change the electronic device to a locked state, or may deactivate (e.g., turn off) the screen. For example, while the electronic device is mounted on the external device, when a specified application is executed in the external device, and thereafter the electronic device is detached from the external device, the electronic device may provide the use of an input/output device for a specified time (e.g., about ten minutes). According to an embodiment of the present disclosure, in cases where an external processor (e.g., an AP) of the connection control module 201 is activated, the external processor may also perform at least some functions of the provision module 240, which are described above.

According to various embodiments of the present disclosure, the connection control module 201 may control the display, processor, or power supply of the electronic device without determining that the electronic device is to be detached from the external device. According to an embodiment of the present disclosure, the electronic device may include a switch that is implemented by hardware and may change data from an external supply source or a power supply path to a path from an internal supply source when the electronic device detects a change of signals through a connector while the electronic device is mounted on the external device. For example, when power supply from the external device is stopped, the switch may simultaneously or substantially simultaneously connect an internal power supply of the electronic device to other elements of the electronic device.

FIGS. 3A and 3B illustrate a plurality of electronic devices functionally connected to each other according to various embodiments of the present disclosure.

Referring to FIG. 3A, a plurality of electronic devices 300 may include a first electronic device 310 and a second electronic device 320. Each of the first and second electronic devices 310 and 320 may be, for example, the electronic device 101. According to an embodiment of the present disclosure, at least one of the first and second displays 312 and 322 may be excluded. According to an embodiment of the present disclosure, the first electronic device 310 may include at least a part of a case (e.g., a battery cover) of the second electronic device 320. According to an embodiment of the present disclosure, the plurality of electronic devices 300 may also be configured as a single electronic device that includes, for example, a first body part that corresponds to the first electronic device 310, the first display 312 functionally connected to the first electronic device 310, a second body part that corresponds to the second electronic device 320, and the second display 322 functionally connected to the second electronic device.

The first and second electronic devices 310 and 320 may be detachably connected to each other. According to an embodiment of the present disclosure, the first electronic device 310 may be connected to the second electronic device 320 such that the position thereof can be changed with respect to the second electronic device 320. For example, in cases where the first electronic device 310 is attached to the second electronic device 320, at least a part of the first electronic device 310 may overlap at least a part (e.g., the front or rear surface) of the second electronic device 320. The first electronic device 310 may include, for example, a cover that can be opened and closed with respect to the second electronic device 320. According to an embodiment of the present disclosure, in cases where the first and second electronic devices 310 and 320 are connected to each other, the second electronic device 320 may operate as a main electronic device, and the first electronic device 310 may operate as an auxiliary electronic device. Additionally, the second electronic device 320 may include, for example, an input button 326. According to an embodiment of the present disclosure, the first electronic device 310 may include, for example, an input button that is the same as or similar to the input button 326. The first and second electronic devices 310 and 320 may have, for example, the same functions, or may include different functions. According to an embodiment of the present disclosure, at least some of the operations that are described as being performed in the first electronic device 310 may be performed, for example, in the second electronic device 320. Furthermore, for example, at least some of the operations that are described as being performed in the second electronic device 320 may be performed in the first electronic device 310.

Referring to FIG. 3B, the plurality of electronic devices 300 functionally connected to each other may be separated into the first electronic device 310 and the second electronic device 320. According to an embodiment of the present disclosure, the first electronic device 310 may include, for example, a first connector 314 that is detachably connected to at least a part (e.g., a side surface) of the second electronic device 320. According to an embodiment of the present disclosure, the second electronic device 320 may include, for example, a second connector 324 that is detachably connected to at least a part (e.g., a side surface) of the first electronic device 310. At least one of the first and second connectors 314 and 324 may include the connector described above in relation to FIG. 2. The first or second connector 314 or 324 may be formed at various locations (e.g., the top, the bottom, the left, the right, the front, the rear, etc.) of the first or second electronic device 310 or 320.

According to an embodiment of the present disclosure, the first and second connectors 314 and 324 may be formed in a detachable physical structure. According to an embodiment of the present disclosure, at least one of the first and second connectors 314 and 324 may include a magnet that detachably connects the first and second connectors 314 and 324 using a magnetic force. According to an embodiment of the present disclosure, the second connector 324 may include a rotatable hinge structure. For example, the second connector 324 may be hingedly coupled to the first electronic device 310 to allow the first and second electronic devices 310 and 320 to rotate using the second connector 324.

According to an embodiment of the present disclosure, the detachable physical structure may connect the first and second connectors 314 and 324, for example, by using a connector (e.g., a connector header or a connector socket). According to an embodiment of the present disclosure, the detachable physical structure may connect the first and second connectors 314 and 324, for example, by using a connection of a contact (e.g., a pogo pin, a spring pin, a plate spring, etc.).

Referring to FIG. 3B, the first connector 314 may include, for example, a first contact point 314a and a second contact point 314b. The second connector 324 may include, for example, a third contact point 324a and a fourth contact point 324b. According to an embodiment of the present disclosure, when at least some of the plurality of contact points (e.g., the first and second contact points 314a and 314b) are separated from the corresponding contact points included in the second connector 324, the first electronic device 310 may recognize the detachment from the second electronic device 320 in advance or at the same time as the detachment by using the order, interval, amount, difference, or the like of a signal change in the separated contact points.

For example, the first and second electronic devices 310 and 320 may be coupled to slide relative to each other using a rail structure. In this case, when the first and second electronic devices 310 and 320 are coupled to each other, for example, the first contact point 314a of the first electronic device 310 may be correspondingly brought into contact with the third contact point 324a of the second electronic device 320, and the second contact point 314b of the first electronic device 310 may be correspondingly brought into contact with the fourth contact point 324b of the second electronic device 320.

For example, when the first electronic device 310 moves along the rail structure to separate from the second electronic device 320, the contact between the first and third contact points 314a and 324a may be released, and then the first and fourth contact points 314a and 324b may make contact with each other. In this way, the first or second electronic device 310 or 320, for example, the first electronic device 310 may be determined to be detached from the second electronic device 320. Similarly, for example, when the first electronic device 310 moves along the rail structure such that the first electronic device 310 is mounted on the second electronic device 320, the first and fourth contact points 314a and 324b may make contact with each other first. After a predetermined period of time, the contact between the first and fourth contact points 314a and 324b may be released, and additionally, the first and third contact points 314a and 324a may make contact with each other. In this way, the first or second electronic device 310 or 320, for example, the first electronic device 310 may be determined to be mounted on the second electronic device 320.

According to an embodiment of the present disclosure, when the first contact point 314a experiences a signal change before the second contact point 314b, the first electronic device 310 may determine that the first electronic device 310 is to be detached from the second electronic device 320. In addition, for example, when the first contact point 314a experiences a signal change after the second contact point 314b, the first electronic device 310 may determine that the first electronic device 310 is to be mounted on the second electronic device 320. Similarly, using the third and fourth contact points 324a and 324b, the second electronic device 320 may determine that the second electronic device 320 is to be mounted on or detached from the first electronic device 310.

According to an embodiment of the present disclosure, the contact points may also be designed to have a predetermined longitudinal length such that the first contact point 314a is simultaneously or substantially simultaneously brought into contact with the fourth contact point 324b when the contact between the first and third contact points 314a and 324a is released. The number, shape, position, or the like of the connectors (e.g., the first and second connectors 314 and 324) and the contact points (e.g., 314a, 314b, 324a, and 324b) corresponding thereto may be modified in various manners.

According to an embodiment of the present disclosure, the first and second electronic devices 310 and 320 may exchange data through wireless communication while being detached from each other. For example, the first and second electronic devices 310 and 320 may include first and second communication modules (not illustrated), respectively, and may transmit and receive a control command for display control over at least one of the first and second displays 312 and 322, or information to be displayed on at least one of the first and second displays 312 and 322. According to an embodiment of the present disclosure, the first and second communication modules (not illustrated) may support, for example, a short-range communication protocol (e.g., Wi-Fi, Wi-Fi direct, wireless gigabits (Wi-Gig), BT, BT low energy (BLE), Zigbee, ultra wideband (UWB), NFC, radio frequency identification (RFID), audio sink, e-field communication (EFC), human body communication (HBC), visible area network, or the like), or a network communication (e.g., the Internet, a LAN, WAN, a telecommunication network, a cellular network, a satellite network, a POTS, or the like). According to an embodiment of the present disclosure, the first and second electronic devices 310 and 320 may also exchange data through wired communication even while being detached from each other.

According to an embodiment of the present disclosure, the first electronic device 310 may be an accessory type (e.g., a card type) of display that can be physically separated from or coupled to the second electronic device 320. For example, a user may separate an accessory type of display from the second electronic device 320 and carry the separated display, and only in case of need, the user may couple (mount) the display with (on) the second display 322. FIGS. 3A and 3B and the contents described in connection therewith are merely various embodiments of the present disclosure, and a structure that may implement any type of detachable electronic device and a control method thereof is not limited thereto. For example, the first or second electronic device 310 or 320 may have a structure of a bracelet, a band, a watch, and various other devices (e.g., glasses, clothes, a headset, earphones, shoes, and the like) that can be worn on a user's body.

FIG. 4 illustrates an example of displaying information using a first electronic device functionally connected to a second electronic device according to various embodiments of the present disclosure.

Referring to FIG. 4, a first electronic device 401 may be, for example, the first electronic device 310 illustrated in FIGS. 3A and 3B. A second electronic device 402 may be, for example, the second electronic device 320 illustrated in FIGS. 3A and 3B. The first electronic device 410 may include, for example, a display 412, a first processor 414, a second processor 416, a memory 418, a first power management module 420, a second power management module 422, a wired communication interface 424a, a wireless communication interface 424b, a wired charging interface 426a, a wireless charging interface 426b, a first switch 428, and a second switch 430. According to an embodiment of the present disclosure, at least some elements included in the first electronic device 401 may be omitted. The second electronic device 402 may include, for example, a display 404. According to an embodiment of the present disclosure, the first processor 414 may include the connection control module 201, which is illustrated in FIG. 2, as a part of a logic performed thereby.

Referring to FIG. 4, the first and second electronic devices 401 and 402 may be connected via a wired communication link 406a, a wireless communication link 406b, a wired charging link 408a, and/or a wireless charging link 408b. The wired communication link 406a or the wired charging link 408a may be connected to, for example, the first connector 314 illustrated in FIG. 3A.

The first electronic device 401 may be detachably connected to the second electronic device 402. The first electronic device 401 may be functionally connected to the second electronic device 402, for example, through a connector (e.g., the first connector 314 or the second connector 324). According to an embodiment of the present disclosure, when the first electronic device 401 is connected to the second electronic device 402, the first electronic device 401 may display data received from the second electronic device 402 on the display 412. Although an embodiment using the display 412 is described in this embodiment of the present disclosure for convenience of description, the present disclosure is not limited thereto, and there may be various embodiments of the present disclosure using various forms of outputs, such as audio, vibration, heat, scent, and the like.

According to an embodiment of the present disclosure, when the first electronic device 401 is connected to the second electronic device 402, at least some elements included in the first electronic device 401 may be deactivated. For example, when the first electronic device 401 is physically coupled to the second electronic device 402, the first electronic device 401 may operate while deactivating at least one of the second processor 416, the second power management module 422, the wireless communication interface 424b, and the wireless charging interface 426b. According to an embodiment of the present disclosure, the first electronic device 401 may be configured by excluding at least some of the elements which are deactivated while the first electronic device 401 is coupled to the second electronic device 402. According to an embodiment of the present disclosure, the second electronic device 402 may perform functions of at least some of the deactivated elements in the first electronic device 401 and may transfer information containing the performance results to the first electronic device 401.

The first processor 414 may perform, for example, operations or data processing to control and/or communicate with one other element in the first electronic device 401. According to an embodiment of the present disclosure, the first processor 414 may process data received from the second electronic device 402.

The wired communication interface 424a may, for example, forward data received from the second electronic device 402 to the first processor 414. According to an embodiment of the present disclosure, the data received from the second electronic device 402 may be forwarded to the display 412 without control of another element of the first electronic device 401 and may be displayed through the display 412. The first processor 414 may, for example, store (e.g., back up) the data received from the second electronic device 402 in the memory 418.

The wired charging interface 426a may, for example, transmit power received from the second electronic device 402 to a battery (not illustrated) included in the first processor 401. According to an embodiment of the present disclosure, the wired charging interface 426a may transmit the power, received from the second electronic device 402, to another element of the first electronic device 401, for example, through the first power management module 420. The first power management module 420 may be, for example, a module for supplying and/or managing power required for operations of the first electronic device 401. For example, the first power management module 420 may supply relatively lower power than the second power management module 422. The first power management module 420 may further include, for example, a power retention module, and may supply necessary power. In cases where the first and second electronic devices 401 and 402 are coupled to each other, the first electronic device 401 may operate, for example, in a terminal mode to output data received from the second electronic device 402 while consuming low power.

The power retention module may include, for example, a circuit for preserving power and/or operations of the first electronic device 401. For example, clock and gating circuitries may be used to implement the power retention module. According to an embodiment of the present disclosure, the power retention module may retain power supplied from the second electronic device 402. For example, the power retention module may manage power for the elements of the first electronic device 401 in a terminal mode or in a sleep mode. For example, the first electronic device 401 may drive the display 412 and the first processor 414 using power supplied from the power retention module while being mounted on the second electronic device 402.

According to an embodiment of the present disclosure, when the first and second electronic devices 401 and 402 are coupled to each other, the first electronic device 401 may receive power from the second electronic device 402 or an external wireless power supply device through the wireless charging interface 426b, and may supply the received power to the other elements included in the first electronic device 401. According to an embodiment of the present disclosure, the first electronic device 401, when receiving power from the second electronic device 402 or another external device in a wired or wireless manner, may stop receiving power from the first electronic device 401.

At least one of the first and second electronic devices 401 and 402 may include a touch sensor on a housing or a display thereof. Various types of sensors (e.g., a digitizer, a magnet, a temperature sensor, a proximity sensor, an antenna, and the like) may be used to detect an external object. According to an embodiment of the present disclosure, when a region where a user (e.g., a user's hand) touches or closely approaches in at least one of the first and second electronic devices 401 and 402 satisfies a specified condition (e.g., location, area, pressure, time, or the like), the first electronic device 401 may determine that the user intends to detach the first electronic device 401 from the second electronic device 402. For example, the determination may be performed based on whether an interval between the time when the user (e.g., the user's hand) is detected in each of the first and second electronic devices 401 and 402 corresponds to a specified interval. In addition, the determination may also be performed further based on whether the first or second electronic device 401 or 402 moves in a specified direction within a specified time after the user (e.g., the user's hand) is detected in the first and second electronic devices 401 and 402.

Similarly, when regions where a user (e.g., a user's hand) touches or approaches the first and second electronic devices 401 and 402 to satisfy another specified condition (e.g., location, area, pressure, time, or the like), the first electronic device 401 may determine that the user intends to mount the first electronic device 401 on the second electronic device 402.

According to various embodiments of the present disclosure, for example, the second electronic device 402 may perform an operation of determining that there will be a change (e.g., separation) in a connection state between the first and second electronic devices 401 and 402, and may transfer the determination result to the first electronic device 401.

When it is determined that there will be a change (e.g., separation) in the connection state between the first and second electronic devices 401 and 402, the first electronic device 401 may display a screen, for example, using data stored in the memory 418 rather than data received from the second electronic device 402. According to an embodiment of the present disclosure, the first processor 414 may switch a data source from the wired communication interface 424a to the memory 418. Additionally, the first processor 414 may transfer information relating to the switching operation to the second electronic device 402. In this case, the second electronic device 402 may transmit data through a wireless communication interface (not illustrated) of the second electronic device 402 and the wireless communication interface 424b of the first electronic device 401. The first electronic device 401 may maintain the screen displayed on the display 412 by using data received through the wireless communication interface 424b when the first electronic device 401 is separated from the second electronic device 402. According to an embodiment of the present disclosure, when it is determined that there will be a change (e.g., separation) in the connection state between the first and second electronic devices 401 and 402, the first electronic device 401 may display a screen using the data stored in the memory 418, and thereafter, when it is determined that the change has occurred, the first electronic device 401 may display a screen using the data received from the second electronic device 402.

According to an embodiment of the present disclosure, the first processor 414 may compare data received through the wired communication interface 424a or the wireless communication interface 424b with the data stored in the memory 418, and when the two pieces of data are not at least partially the same as each other, the first processor 414 may update the data stored in the memory 418 to the data received through the wired communication interface 424a or the wireless communication interface 424b. According to an embodiment of the present disclosure, the first processor 414 may periodically or intermittently store data received though the wired communication interface 424a or the wireless communication interface 424b.

According to an embodiment of the present disclosure, when it is determined that there will be a change (e.g., separation) in the connection state between the first and second electronic devices 401 and 402, the first electronic device 401 may stop a charging operation that uses power supplied from the second electronic device 402. The first electronic device 401 may maintain the power thereof, for example, by using the first power management module 420. In addition, for example, the first electronic device 401 may change the second power management module 422 from a deactivated state to an activated state. For example, the first power management module 420 may be deactivated when the second power management module 422 is activated. The second power management module 422 may supply power to the second processor 416. The second power management module 422 may, for example, supply or control a power (e.g., current) greater than the first power management module 420. According to an embodiment of the present disclosure, the first electronic device 401 may not deactivate the first power management module 420, and may perform power supply and/or power management using the first and second power management modules 420 and 422.

The second switch 430 may selectively provide power to the elements included in the first electronic device 401 from the first power management module 420 to the second power management module 422. The switching operation may be performed, for example, under the control of the first or second processor 414 or 416, or hardware switching may also be performed by detecting, by the second switch 430, a change in the connection state between the first and second electronic devices 401 and 402.

When it is determined that there will be a change (e.g., separation) in the connection state between the first and second electronic devices 401 and 402, the first processor 414 may change the second processor 416 from an deactivated state to an activated state. The activation of the second processor 416 may include, for example, booting of the second processor 416. The first processor 414 may be, for example, driven by using lower power and/or frequency than the second processor 416. In addition, for example, the first processor 414 may be a processor that provides lower performance than the second processor 416. According to an embodiment of the present disclosure, the first processor 414 may be a processor that performs processing on at least some elements (e.g., a motion sensor (e.g., an acceleration sensor 740E), a microphone (e.g., a microphone 788), a touch sensor (e.g., a touch panel 752), or the like) of the first electronic device 401 when the first electronic device 401 operates in a low-power mode (e.g., a sleep mode). According to an embodiment of the present disclosure, the first processor 414 may also be referred to as, for example, a micro control unit (MCU), and the second processor 416 may also be referred to as, for example, an AP. The first and second processors 414 and 416 may also be included in a single processor.

According to an embodiment of the present disclosure, when the second processor 416 is activated, the first processor 414 may be changed to a deactivated state (e.g., a sleep or off state). When the first processor 414 is deactivated, the second processor 416 may perform operations or data processing based on control and/or communication from the other elements of the first electronic device 401. According to an embodiment of the present disclosure, the first electronic device 401 may also perform operations or data processing without deactivating the first processor 414.

The first switch 428 may switch, for example, a data path for the display 412 from the wired communication interface 424a to the second processor 416. The switching operation may be performed, for example, under the control of the first or second processor 414 or 416, or the switching may also be performed by detecting, by the first switch 428, a change in the connection state between the first and second electronic devices 401 and 402. The first electronic device 401, when being separated from the second electronic device 402, may operate in a standalone mode in which the first electronic device 401 may operate without the second electronic device 402. According to an embodiment of the present disclosure, a change between a terminal mode and a standalone mode may be performed, for example, according to a user's selection input. According to an embodiment of the present disclosure, a change between a terminal mode and a standalone mode may be performed, for example, according to the distance between the first and second electronic devices 401 and 402.

When it is determined that there will be a change (e.g., separation) in the connection state between the first and second electronic devices 401 and 402, the first electronic device 401 may be wirelessly supplied with power, for example, through the wireless charging interface 426b. According to an embodiment of the present disclosure, the wireless charging interface 426b may include, for example, a circuit that may serve as a source or a target for inductive or resonance wireless power supply system. The circuit operating as a source may include, for example, a transmission resonator (e.g., a Tx resonator), an amplifier, and a driver (e.g., a gate driver). The circuit operating as a target may include, for example, a reception resonator (e.g., an Rx resonator), a matching circuit, a rectifier circuit, and a regulator circuit. According to an embodiment of the present disclosure, the wireless charging interface 426b may include an MCU that can control elements of the wireless charging interface 426b. According to an embodiment of the present disclosure, the wireless charging interface 426b may also include an out-band communication system, such as Zigbee, etc., or an in-band communication system for communication between the source and the target. According to an embodiment of the present disclosure, some of the elements described above may be omitted, or other elements may be added, and another type of wireless power technology may also be used.

The power received by the first electronic device 401 in a wireless manner may be provided through various methods.

For example, when a first camera application that is executed in the second electronic device 402 cannot be executed in the first electronic device 401, the first electronic device 401 may execute a second camera application that differs from the first camera application.

According to an embodiment of the present disclosure, when the first electronic device 401 executes an application that may perform at least some functions of an application that is currently executed in the second first electronic device 402, the second electronic device 402 may accordingly stop executing the corresponding application. According to an embodiment of the present disclosure, the first electronic device 401, while being separated from the second electronic device 402, may periodically or intermittently synchronize data, which is input or output through an application executed in the first electronic device 401 in relation to the second electronic device 402, with the second electronic device 402. According to an embodiment of the present disclosure, when the first electronic device 401 is mounted on the second electronic device 402 or is located within a predetermined distance from the second electronic device 402, the first electronic device 401 may transfer, to the second electronic device 402, the data which is input or output through the application executed in the first electronic device 401 to the second electronic device 402.

The first electronic device 401, while being mounted on the second electronic device 402, may receive and store data created or acquired through an application executed in the second electronic device 402. For example, when the first electronic device 401 is mounted to a third electronic device (not illustrated) within a predetermined time after being detached from the second electronic device 402, the first electronic device 401 may provide the data to the third electronic device. The third electronic device may be a device that is specified in advance while the first electronic device is mounted on the second electronic device, or a device that is identified to belong to the same user. According to an embodiment of the present disclosure, the third electronic device, when the first electronic device 401 is mounted thereon, may represent (e.g., display) data received from the first electronic device 401 by executing an application that is executed in the second electronic device 402.

For example, the second electronic device 402, while the first electronic device 401 is mounted thereon, may execute a camera application according to a request of a user or an external device (e.g., the first electronic device 401). The second electronic device 402 may store an image (e.g., a still image or a moving image) acquired through the camera application in at least one of the first and second electronic devices 401 and 402. According to an embodiment of the present disclosure, when it is determined that the first electronic device 401 is already detached or is to be detached from the second electronic device 402, images acquired while the first electronic device 401 is mounted on the second electronic device 402 may be transmitted to the first electronic device 401. The images may be used by the first electronic device 401 according to a specified condition (e.g., time or distance). When the specified condition is not satisfied, the images may be deleted from the first electronic device 401. The specified condition may include, for example, an elapsed time from when the first electronic device 401 is separated from the second electronic device 402. In addition, the specified condition may include, for example, the distance between the first and second electronic devices 401 and 402. According to an embodiment of the present disclosure, when the first electronic device 401 is detached from the second electronic device 402 and mounted on the third electronic device, the images may be transmitted to the third electronic device. According to an embodiment of the present disclosure, when the first electronic device 401 is detached from the third electronic device, the images may be deleted from the third electronic device. According to an embodiment of the present disclosure, the first electronic device 401, while being mounted on the second electronic device 402, may serve as a device that inputs and outputs authentication information under the control of the second electronic device 402. In cases where the first electronic device 401 is detached from the second electronic device 402, the first electronic device 401 may directly process authentication information. According to an embodiment of the present disclosure, the first electronic device 401 may determine a security level when the first electronic device 401 is detached from the second electronic device 402 based on an input received while mounted on the second electronic device 402. For example, while a payment related application is executed in the second electronic device 402, when the first electronic device 401 is separated without a separate user input, a user may perform a payment to the extent of a first amount of money through the first electronic device 401. For example, while a payment related application is executed in the second electronic device 402, when the first electronic device 401 is separated after authentication of a user (e.g., a signature, a face, a fingerprint, etc.), the user may perform a payment to the extent of a second amount of money through the first electronic device 401. According to an embodiment of the present disclosure, an electronic payment level (e.g., an amount of money) that can be performed through the first electronic device may vary according to authentication methods.

According to an embodiment of the present disclosure, the first electronic device 401, while being mounted on the second electronic device 402, may provide a display relating to a camera application executed in the second electronic device 402.
