Various embodiments of the present invention relate to an electronic device and a method for sensing a state thereof.
Electronic devices (e.g., mobile terminals, smart phones, or wearable devices) may provide various functions. For example, in addition to a basic voice communication function, a smart phone may provide various functions such as a short-range wireless communication (e.g., Bluetooth, Wi-Fi, or near field communication (NFC)) function, a mobile communication (3rd generation (3G), 4G, 5G, etc.) function, a music or video playback function, a photographing function, or a navigation function.
The electronic devices may include parts (e.g., sensors) for determining various states (or conditions) (e.g., fall, or impact) which may occur inside or outside the electronic device.
In general, an electronic device determines a state of the electronic device by periodically reading raw data from a sensor. As such, to read the sensor's raw data, the electronic device has a problem that a processor operates relatively frequently and increases current consumption. For example, the processor must periodically wake up from an inactive state (e.g., sleep) to read the raw data.
In various embodiments of the present invention, the sensor may monitor the state (e.g., occurrence of free fall and/or impact) of the electronic device, and if detecting a designated state, transmit it to the processor through an interrupt pin included in the sensor.
In addition, various embodiments of the present invention may store in a memory and/or provide to a user various information related to the detected state.
An electronic device according to various embodiments of the present invention may include, for example, a processor and a first interrupt pin and a second interrupt pin operatively connected to the processor, and a sensor configured to detect a movement of the electronic device, wherein the sensor may be configured to transmit, when detecting a free fall of the electronic device, a first designated signal to the processor using the first interrupt pin, and transmit, when detecting an impact state for the electronic device, a second designated signal to the processor using the second interrupt pin.
An electronic device according to various embodiments of the present invention may include, for example, a memory, a sensor including a first interrupt pin and a second interrupt pin, and at least one processor operatively connected to the memory and the sensor, wherein the at least one processor may be configured to receive a first designated signal indicating a free fall of the electronic device through the first interrupt pin or a second designated signal indicating an impact of the electronic device through the second interrupt pin, determine a state of the electronic device based on at least one of the first designated signal and the second designated signal, and perform at least one of storing information related to the determined state in the memory or notifying to a user.
An electronic device according to various embodiments of the present invention may include, for example, a first sensor including a first interrupt pin and a second interrupt pin, a second sensor, and at least one processor operatively connected to the first sensor and the second sensor, wherein the at least one processor may be configured to receive at least one of a first designated signal indicating a free fall of the electronic device through the first interrupt pin or a second designated signal indicating an impact within a first impact range through the second interrupt pin, and receive a fourth designated signal indicating an impact within a second impact range which is greater than the first impact range from the second sensor.
A method of detecting a state of an electronic device including a sensor which includes a first interrupt pin and a second interrupt pin according to various embodiments of the present invention may include receiving at least one of a first designated signal indicating a free fall of the electronic device through the first interrupt pin or a second designated signal indicating an impact of the electronic device through the second interrupt pin, determining a state of the electronic device based on at least one of the first designated signal and the second designated signal, and performing at least one of storing information related to the determined state in a memory of the electronic device or notifying to a user.
An electronic device according to various embodiments of the present invention may reduce current consumption as a processor does not periodically operate to read sensor's raw data, and operates only if receiving an interrupt from a sensor. In addition, various embodiments of the present invention may accurately recognize various states related to the electronic device, and provide related information to a user.
Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. Although the present document illustrates specific embodiments in the drawings and describes related details, it is not intended to limit various embodiments of the present invention to specific forms. For example, it is obvious to those skilled in the art to which the present invention pertains that the embodiments of the present invention may be variously changed.

The sensor module 276 may set a first threshold and a second threshold for the free fall and/or collision detection through registers. The first threshold may be set through a first register as shown in the following Table 1. For example, if the first register of the sensor module 276 is set to “010”, the first threshold may be 250 mg. Table 1 is only an example and does not limit the present invention.
Meanwhile, the second threshold for the impact detection may be a product of 1 LSB and a second register value. Herein, 1 LSB may be a value obtained by dividing a full scale range of the sensor module 276 by 64 mg. The full scale range indicates an output data rate (ORD) of an acceleration sensor and indicates how many data may be sampled for 1 second. The full scale range may be 1.6 Hz˜6.66 kHz. The second register has 6 bits, and may have a value of 1 through 63.
The first threshold and the second threshold may be a sum of vector values of three axes (X, Y, and Z axes) of the acceleration sensor.
The sensor module 276 according to an embodiment of the present invention may include at least two interrupt pins 271 and 272. For example, the sensor module 276 may include the first interrupt pin 271 which transmits a first designated signal indicating the free fall occurrence of the electronic device 201 to the processor 221 and the second interrupt pin 272 which transmits a second designated signal indicating the impact occurrence to the processor 221. As shown in
The sensor module 276 may include a communication terminal 273 for data communication with the processor 221. For example, the communication terminal 273 may support a synchronization serial communication protocol such as I2C. However, it does not limit embodiments of the present invention.
The processor 221 according to an embodiment of the present invention may recognize the free fall and/or impact occurrence by receiving the first designated signal and/or the second designated signal through the first interrupt pin 271 and/or the second interrupt pin 272 of the sensor module 276.
The processor 221 according to an embodiment of the present invention may recognize state information (e.g., free fall, impact occurrence, fall height information, or floor material), based at least in part on the first designated signal and/or the second designated signal, store the recognized state information in the memory 230, and notify it to a user. The detailed descriptions will be described later with reference to

The detailed description will be described later with reference to
The electronic device 201 according to an embodiment of the present invention as mentioned above may prevent unnecessary current consumption as the processor 221 does not recognize the free fall and/or impact occurrence by periodically reading the raw data of the sensor module 276, and receives the free fall and/or impact occurrence through the interrupt pins 271 and 272 of the sensor module 276 only if the free fall and/or the impact is detected by the sensor module 276.

As an identifying result of the operation 601, if the first designated signal is not received, the processor according to an embodiment of the present invention may identify whether a second designated signal related to an impact is received, in operation 603. The second designated signal may be received through a second interrupt pin (e.g., the second interrupt pin 272 or the second interrupt pin 472) of the sensor module.
As an identifying result of the operation 603, if the second designated signal is not received, the processor may return to operation 601. As the identifying result of the operation 603, if the second designated signal is received, the processor may determine that an external impact is occurred, rather than the impact due to the fall, in operation 605. The processor may proceed to operation 619 and store and/or provide state information in a memory (e.g., the memory 130, the memory 230, and the memory 430). For example, the processor may store an occurrence time and/or an impact degree of the external impact in the memory. The processor may control a display (e.g., the display device 160) to output a pop-up message notifying the occurrence and the impact degree of the external impact. The processor may control a speaker (e.g., the sound output device 155) and/or a vibration motor to output a designated effect sound and/or vibrations of a designated pattern together.
As the identifying result of the operation 601, if the first designated signal is received, the processor according to an embodiment of the present invention may store a start time, in operation 607. For example, the processor may store a time at which the first designated signal is received as the start time.
The processor according to an embodiment of the present invention may identify whether the first designated signal is received every designated period (e.g., 400 ms), in operation 609. As an identifying result of the operation 609, if the first designated signal is not received every designated period (e.g., if the first designated signal is not received within the designated period), in operation 611, the processor may determine that an impact less than a second threshold for the impact detection occurs. For example, the processor may determine its fall on an object of a soft material (e.g., cotton) which may absorb shock. The processor may proceed to operation 619 and store and/or provide state information to the memory. For example, the processor may store a free fall occurrence time in the memory. The processor may control a display (e.g., the display device 160) to output a pop-up message notifying the occurrence of the free fall. According to an embodiment, the processor may output a designated notification sound through a speaker (e.g., the sound output device 155) or vibrate a vibration motor (not shown) in a designated pattern. This is to prevent the user from moving to another place and losing the electronic device without recognizing the fall of the electronic device. According to an embodiment, the processor may measure ambient light through an illuminance sensor, turn on the display if it is below a designated illuminance, or blinker a light emitted diode (LED) (e.g., a flash of the camera). This is to enable the user to easily discover the electronic device.
As the identifying result of the operation 609, if the first designated signal is received at the designated period, the processor may identify whether a second designated signal is received, in operation 613. If the second designated signal is not received as an identifying result of the operation 613, the processor may return to operation 609. By contrast, if the second designated signal is received as the identifying result of the operation 613, the processor may store an end time, in operation 615. For example, the processor may store a time at which the second designated signal is received as the end time.
The processor storing the end time may determine free fall occurrence, in operation 617. In operation 619, the processor may store and/or provide state information in a memory. For example, the processor may generate height information of the free fall using the start time and the end time, and store the free fall occurrence time, the impact level and/or the height information due to the free fall in the memory. The processor may control the display to output a pop-up message notifying the free fall occurrence, the impact level and/or height due to the free fall. The processor may control to output a designated sound effect and/or vibrations of a designated pattern together.

The auxiliary processor according to an embodiment of the present invention may calculate a height, in operation 703. For example, the auxiliary processor may calculate the height using the following Equation 1.
In Equation 1, “h” denotes the height, g denotes the gravitational acceleration 9.8 m/s2, and “t” denotes the difference of the start time and the end time.
The auxiliary processor according to an embodiment of the present invention may identify whether the calculated height exceeds (or equal to or greater than) a designated value, in operation 705. If the calculated height is equal to or less than (or falls below) the designated value as an identifying result of the operation 705, the auxiliary processor may stop providing the height information. According to an embodiment, the auxiliary processor may temporarily store the height information, and if a main processor (e.g., the main processor 121 or the main processor 421) is inactive (or wakes up) by other event, may transmit the height information the main processor to store in the memory.
By contrast, if the calculated height exceeds (or is equal to or greater than) the designated value as the identifying result of the operation 705, the auxiliary processor may transmit the height information to the main processor, in operation 707.
According to some embodiment, if the main processor is active, the calculated height information may be directly transmitted to the main processor, and if the main processor is inactive, the calculated height information may be transmitted to the main processor only if the calculated height information exceeds the designated value. This is to prevent the current consumption by lowering the frequency at which the main processor wakes up.

For example, if the electronic device 1001 falls, a sensor module (e.g., the sensor module 176, the sensor module 276, the sensor module 476, the sensor module 876, or the sensor module 976) of the electronic device 1001 may detect the fall, and transmit the first designated signal to a processor (e.g., the processor 120, the processor 221, the main processor 421, the processor 820, or the main processor 921) (or an auxiliary processor (e.g., the auxiliary processor 423, the auxiliary processor 923)) through a first interrupt pin (e.g., the first interrupt pin 271, the first interrupt pin 471, or the first interrupt pin 871). If the processor of the electronic device 1001 may, if determining that the fall is maintained over a designated time (e.g., 0.5 seconds), control a first folding module 1111a and a second folding module 1111b included in the electronic device 1001 to fold the electronic device 1001.
The first folding module 1111a and the second folding module 1111b may be actuators for folding the electronic device 1001. For example, the first folding module 1111a and the second folding module 1111b may be motors. The first folding module 1111a and the second folding module 1111b may be included in a hinge 1113. The first folding module 1111a may, under control of the processor (or the auxiliary processor), fold the electronic device 1001, by transmitting a force of a close direction to an arm 11a connected with a first portion 1112a to rotate the first portion 1112a of a housing 1112 to a second portion 1112b. Similarly, the second folding module 1111b may, under control of the processor (or the auxiliary processor), fold the electronic device 1001, by transmitting the force of the close direction to an arm 11b connected with the second portion 1112b to rotate the second portion 1112b of the housing 1112 toward the first portion 1112a.
According to some embodiment, if receiving the first designated signal according to the free fall detection through the first interrupt pin from the sensor module, the processor (or the auxiliary processor) of the electronic device 1001 may identify the state (e.g., folding or unfolding) of the electronic device 1001, and control the first folding module 1111a and the second folding module 1111b to fold the electronic device 1001 in the unfolding state.
The electronic device 1001 according to an embodiment of the present invention described above may be automatically folded upon detecting the fall, and thus protect a display 1060 from the impact. For example, the electronic device 1001 may be completely folded not to the display 1060 to outside, or may, even if it is not completely folded, protect the display 1060 from directly hitting an external object (e.g., the ground) thus prevent damage of the display 1060.
