Description

SENSOR DEVICE AND ELECTRONIC DEVICE OBTAINING INFORMATION FROM THE SENSOR DEVICE

The disclosure relates to a sensor device and an electronic device obtaining information from the sensor device. More particularly, the disclosure relates to a sensor device detecting a sensing value related to the operation of an electronic device and an electronic device obtaining the sensing value related to the operation of the electronic device from the sensor device.

Sensor devices may obtain sensing values related to the operation of an electronic device. For example, a washer may include a door sensor for identifying that the door stays closed before the washer starts to operate and a water level sensor for detecting the water level to maintain a water level appropriate for washing. A dryer equipped with a humidity sensor may identify whether the laundry has been sufficiently dried based on the humidity value obtained from the humidity sensor. A refrigerator with a temperature sensor may identify whether the inside of the refrigerator remains in an adequate temperature range based on the temperature obtained from the temperature sensor.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

The sensor device of the related art for obtaining sensing values related to the operation of an electronic device may be part of the electronic device which may be integrally embedded in the electronic device. The conventional sensor device may not obtain sensing values from away from the surface of the electronic device. For example, dryers typically have an electrode sensor embedded in the inner surface thereof. Thus, although the electrode sensor is placed close to the laundry, the electrode sensor may not obtain a sensing value from the laundry which is away from the inner surface of the dryer. Thus, in the case of the conventional sensor device, the sensing value detected by the sensor device may differ from the sensing value actually required.

Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide a sensor device and an electronic device obtaining information from the sensor device.

Another aspect of the disclosure is to provide a sensor device may be a separate device from the electronic device, rather than embedded in the electronic device.

Another aspect of the disclosure is to provide a sensor device may receive power via an energy harvester and transmit the sensing value and information for the magnitude of the harvested electric energy to the electronic device.

Another aspect of the disclosure is to provide an electronic device may perform operations based on the sensing value and the information indicating the magnitude of the harvested electric energy received from the sensor device.

Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

In accordance with an aspect of the disclosure, a sensor device is provided. The sensor device includes an energy harvester configured to generate electric energy, a monitoring circuit, a sensor, a communication circuit, and at least one processor configured to control the communication circuit to communicate a signal to establish a communication connection to another electronic device, obtain information indicating a magnitude of the generated electric energy via the monitoring circuit, obtain a sensing value via the sensor, and control the communication circuit to transmit the information indicating the magnitude of the generated electric energy and the sensing value to the other electronic device.

In accordance with another aspect of the disclosure, an electronic device is provided. The electronic device includes a communication circuit, an actuator, and at least one processor configured to control the communication circuitto communicate a signal to establish a communication connection with a sensor device configured to generate electric energy, receive information indicating a magnitude of the generated electric energy from the sensor device via the communication circuit, identify an operation routine of the actuator for processing laundry based on the information indicating the magnitude of the generated electric energy, control the actuator to operate according to the operation routine, receive a sensing value from the sensor device via the communication circuit while the actuator operates according to the operation routine, and change the operation routine of the actuator for processing laundry based on the sensing value.

In accordance another aspect of the disclosure, an electronic device is provided. The electronic device includes a communication circuit, an actuator, and at least one processor configured to control the communication circuit to communicate a signal to establish communication connection with a sensor device configured to generate electric energy, receive a sensing value and information indicating a magnitude of the generated electric energy from the sensor device via the communication circuit, and control an operation of the actuator based on at least one of the information indicating the magnitude of the generated electric energy or the sensing value.

Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the disclosure.

As is apparent from the foregoing description, according to various embodiments, there are provided a sensor device and an electronic device obtaining information from the sensor device. The sensor device may be a separate device from the electronic device, rather than embedded in the electronic device. The sensor device may receive power via an energy harvester and transmit the sensing value and information for the magnitude of the harvested electric energy to the electronic device. Since the sensor device is a separate device from the electronic device, the sensor device may detect sensing values in positions where sensing is actually required, rather than the surface of the electronic device. Thus, the electronic device may obtain more accurate sensing values than those obtained from the surface of the electronic device.

According to various embodiments, since the electronic device receives information for the magnitude of harvested electric energy from the sensor device, the sensor device may consider the received information for the magnitude of the harvested electric energy when the operation of the actuator is controlled. Thus, the electronic device may assist the sensor device in seamlessly receiving energy or may properly control the operation of the actuator.

FIGS. 3B and 3C are graphs illustrating operation of a hysteresis switch according to various embodiments of the disclosure.

Referring to FIG. 3B, when the input voltage is lower than a low voltage threshold (VL), the output voltage is 0. When the input voltage was lower than VL and then increases to be higher than VL but lower than a high voltage threshold (VH), the output voltage is still 0. When the input voltage is higher than VH, the output voltage is equal to the input voltage. When the input voltage was higher than VH and then decreases to be higher than VL but lower than VH, the output voltage is identical to the input voltage.

In the interval when the input voltage increases starting from 0, the hysteresis switch is turned on at the point when the input voltage is VH. Thereafter, the input voltage goes higher than VH and then reduces. In the interval when the input voltage is higher than VH and then reduces, the hysteresis switch is turned off at the point when the input voltage is VL. Thereafter, the input voltage goes lower than VL and then increases. In the interval when the input voltage is lower than VL and then increases, the hysteresis switch is turned on at the point when the input voltage is VH.

According to an embodiment, VL may be set as a minimum voltage at which the processor may be driven. It may be identified that the above-described hysteresis switch delays the time when the switch is turned off in the context where the input voltage is reducing, with the hysteresis switch on and delays the time when the switch is turned on in the context where the input voltage is increasing, with the hysteresis switch off. Thus, the hysteresis switch may delay the time when no power is supplied to the processor in the context where the output power of the energy harvester reduces and delay the time when power is supplied to the processor until more power is accumulated in the energy storage device in the context where the output power of the energy harvester increases, thereby enabling power to be supplied to the processor for a longer time. Further, as the harvested energy is varied, the processor and the communication module may be prevented from frequently turning on/off, ensuring a stable communication connection between the sensor device and the electronic device.

FIG. 4A is a view illustrating a structure of an induction mechanism harvester according to an embodiment of the disclosure.

Referring to FIG. 4A, according to an embodiment, an induction mechanism harvester 400a may include a guide 410a, a coil 420a wound around the guide, and a magnet 430a disposed to be movable in the guide. The magnet 430a may be moved in the guide 410a as the induction mechanism harvester 400a moves. When the magnet 430a passes a portion of the guide 410a where the coil 420a is disposed, an induced electromotive force is generated from the coil 420a by a variation in the magnetic flux in the section of the coil 420a.

In the example shown in FIG. 4A, the guide 410a may be a cylinder with a diameter of 8 mm and a height of 50 mm. In the example shown in FIG. 4A, a side surface of the cylindrical guide 410a where the coil 420a is disposed may be 10 mm wide. In the example shown in FIG. 4A, the magnet 430a may be a cylinder with a diameter of 7 mm and a height of 15 mm. The sizes related to the guide 410a, coil 420a, and magnet 430a shown in FIG. 4A are merely examples. According to an embodiment, the induction mechanism harvester 400a may include a plurality of coils 420a. According to an embodiment, the magnet 430a may be elliptical in shape. According to an embodiment, the magnet 430a may be shaped and sized not to be overturned inside the guide 410a.

FIG. 4B is a view illustrating a structure of a housing in which an induction mechanism harvester is placed according to an embodiment of the disclosure.

Referring to FIG. 4B, in the sensor device 400b, an induction mechanism harvester includes a guide 410b, coil 420b, and magnet 430b that may be disposed in the housing 440b of the sensor device 400b. According to an embodiment, the housing 440b of the sensor device 400b may be spherical in shape. According to an embodiment, the housing 440b of the sensor device 400b may have various stereoscopic shapes, such as a hexahedron, tetrahedron, elliptical sphere, or prolate spheroid. The details of the induction mechanism harvester shown in FIG. 4B are the same as those described above in connection with FIG. 4A, and no further description thereof is given below. In particular, when the sensor device is configured to sense temperature, humidity, or harvesting output in a dryer, the exterior size may be a minimum of 50 mm or more vertically and horizontally to produce sufficient power required for driving the sensor.

FIGS. 5A and 5B are views illustrating a structure of a sensor device with a plurality of induction mechanism harvesters according to various embodiments of the disclosure.

Specifically, FIG. 5A illustrates an example cross section of the sensor device 500a.

Referring to FIG. 5A, a first portion 501a and second portion 502a of the housing integrally constitute the tetrahedral housing. The first portion 511a of the first guide and the second portion 512a of the first guide integrally constitute the guide of the first induction mechanism harvester. The first portion 521a of the second guide and the second portion 522a of the second guide integrally constitute the guide of the second induction mechanism harvester. The first induction mechanism harvester and the second induction mechanism harvester may be part of the induction mechanism harvester described above in connection with FIG. 4A.

Although FIG. 5A illustrates that the first induction mechanism harvester and the second induction mechanism harvester are integrally formed with each other, the sensor device 500a may be designed so that the first induction mechanism harvester and the second induction mechanism harvester are separated from each other according to an embodiment.

The sensor device 500a of FIG. 5A includes two induction mechanism harvesters which are perpendicular to each other. Given that the induction mechanism harvester produces electric energy as the sensor device 500a moves and that electronic devices, such as dryers and washers, typically and mainly perform circular rotating motions or falling motions, if the sensor device 500a includes only one cylindrical induction mechanism harvester, when the sensor device 500a is disposed so that the height direction of the cylinder corresponding to the guide of the induction mechanism harvester is parallel to a normal of the plane formed by the direction of motion of the electronic device, the magnet included in the induction mechanism harvester does not move and, thus, no electric energy is produced. Thus, as the sensor device 500a includes two cylindrical induction mechanism harvesters perpendicular to each other, failure to produce electric energy may be prevented.

The example of FIG. 5A where two cylindrical induction mechanism harvesters are perpendicular to each other is merely an example. For example, the angle between the two cylindrical induction mechanism harvesters may be varied. Although the angle between the two cylindrical induction mechanism harvesters is not a right angle, failure to produce electric energy may be prevented as long as the two cylindrical induction mechanism harvesters are not perfectly parallel with each other.

According to an embodiment, the sensor device 500a may include three or more induction mechanism harvesters.

According to an embodiment, the first guide 510b and the second guide 520b may be shaped to have both the ends closed at least partially.

Referring to FIG. 5B, the first guide 510b and the second guide 520b being perpendicular to each other is merely an example, and the angle between the first guide 510b and the second guide 520b may be varied. Referring to FIG. 5B, the distance between the center of the first guide 510b and the center of the second guide 520b may be 40 mm or more.

Referring to FIG. 9, according to an embodiment, an electronic device 900 may include a processor 910. According to an embodiment, the processor 910 may receive, via the communication module 920, a sensing value and information indicating the magnitude of energy generated by a sensor device from the sensor device generating electric energy. According to an embodiment, the processor 910 may control the operation of the actuator or other hardware based on the sensing value and the information indicating the magnitude of energy generated by the sensor device. For example, when the electronic device 900 is a dryer and receives a temperature and/or humidity as the sensing value from the sensor device, if the temperature and/or humidity is higher than a reference value, the hardware of the electronic device 900 may be controlled. When the electronic device 900 is a washer, and a detergent quantity, as the sensing value, is received from the sensor device, if the detergent quantity is more than an adequate amount, the hardware of the electronic device 900 may be controlled so that more water may be supplied.

In another example, when the electronic device 900 is a refrigerator and receives the information indicating the magnitude of energy generated by the sensor device from the sensor device including a photoelectric harvester, if the magnitude of energy generated by the sensor device is less than a predetermined value, the processor 910 of the electronic device 900 may increase the output of light inside the refrigerator.

According to an embodiment, the processor 910 may be a single processor or multiple processors. The processor 910 may execute, for example, software to control at least one other component (e.g., a hardware or software component) of the electronic device 900 and may perform various data processing or computation. According to one embodiment, as at least part of the data processing or computation, the processor 910 may load a command or data received from another component (e.g., communication module 920) onto a volatile memory, process the command or the data stored in the volatile memory, and store resulting data in a non-volatile memory. According to an embodiment, the processor 910 may include a main processor (e.g., a CPU or an AP), and an auxiliary processor (e.g., a GPU, an ISP, a sensor hub processor, or a CP) that is operable independently from, or in conjunction with, the main processor. Additionally or alternatively, the auxiliary processor may be adapted to consume less power than the main processor, or to be specific to a specified function.

According to an embodiment, the electronic device 900 may include a communication module 920. The communication module 920 may be used to receive a sensing value and information indicating the magnitude of energy generated by the sensor device from the sensor device. According to an embodiment, the communication module 920 may perform BLE, Bluetooth, Zigbee, Wi-Fi, or IR communication. According to an embodiment, the communication module 920 may be implemented in the same chip as the processor 910.

The communication module 920 may establish a wireless communication channel between the electronic device 900 and an external electronic device (e.g., the sensor device 200c) and support communication via the established communication channel. The communication module 920 may include one or more communication processors that are operated independently from the processor 910 (e.g., an application processor) and supports wireless communication. According to an embodiment, the communication module 920 may include a wireless communication module (e.g., a cellular communication module, a short-range wireless communication module, or a GNSS communication module). A corresponding one of these communication modules may communicate with the external electronic device via the first network (e.g., a short-range communication network, such as BluetoothTM, Wi-Fi direct, or IrDA) or the second network (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or WAN). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module may identify and authenticate the electronic device 900 in a communication network, such as the first network or the second network, using subscriber information (e.g., IMSI) stored in the subscriber identification module.

According to an embodiment, the electronic device 900 may include a power supply circuit 930. According to an embodiment, the power supply circuit 930 may include at least one of a battery, a capacitor, or a supercapacitor. According to an embodiment, the power supply circuit 930 may be electrically connected to an external power source to transfer external power to the processor 910.

According to an embodiment, the electronic device 900 may include an actuator 940. The actuator 940 may cause a mechanical movement, emit light, or vary the ambient temperature using an electrical signal received from the processor 910. According to an embodiment, the actuator 940 may be a dryer or washer and may include a motor embedded in the electronic device 900. According to an embodiment, the electronic device 900 may be a refrigerator, and the actuator 940 may include at least one of a light or cooler inside the refrigerator.

According to an embodiment, the processor 910 of the electronic device 900 may display a message to allow the sensor device to be positioned in the electronic device 900 on the display 950 in response to establishing a connection with the sensor device (e.g., the sensor device 200c) via the communication module 920. According to an embodiment, the processor 910 of the electronic device 900 may output a message to allow the sensor device to be positioned in the electronic device 900 in the form of a sound in response to establishing a connection with the sensor device 200c via the communication module 920. In this case, the sensor device 200c may establish a connection with the communication module 920 of the electronic device 900 based on the electric energy generated as the user shakes the sensor device 200c.

According to an embodiment, the processor 910 of the electronic device 900 may display, on the display 950, information which is based on at least part of the information indicating the magnitude of energy generated by the sensor device and the sensing value received from the sensor device (e.g., the sensor device 200c) via the communication module 920. For example, when the electronic device 900 is a dryer, the processor 910 may display at least one of the temperature or humidity in the dryer, the charging voltage of the sensor device, or estimated time to complete drying on the display 950. For example, when the electronic device 900 is a washer, the processor 910 may display at least one of the amount of laundry, temperature, charging voltage of the sensor device, or wash time expected on the display 950. According to an embodiment, the processor 910 of the electronic device 900 may store a history for the sensing value and the information indicating the magnitude of energy generated by the sensor device in a memory (not shown) and may display information which is based on the history for the sensing value and information indicating the magnitude of energy generated by the sensor device stored in the memory on the display 950.

FIG. 10 is a view illustrating operations performed by a sensor device and an electronic device according to an embodiment of the disclosure.

Referring to FIG. 10, a flow diagram 1000 illustrates operations of the sensor device and the electronic device. In operation 1010, the electronic device 1002 (e.g., the processor 910) may control the actuator 940 to perform a first operation. According to an embodiment, the first operation may be identified based on a sensing value received from the sensor device 1001 (e.g., the processor 270c).

In operation 1020, the sensor device 1001 (e.g., the processor 270c) may obtain information indicating the magnitude of the generated electric energy via the monitoring circuit (e.g., the monitoring circuit 260c). According to an embodiment, the electric energy may be generated as the actuator 940 performs the first operation. According to an embodiment, the obtained information may be at least one of the current, voltage, or power supplied to the processor 270c. In operation 1030, the sensor device 1001 (e.g., the processor 270c) may transmit the information indicating the magnitude of the generated electric energy to the electronic device 1002 via the communication module (e.g., the communication module 290c).

In operation 1040, the electronic device 1002 (e.g., the processor 910) may identify whether the magnitude of the generated electric energy is larger than a preset value based on the information indicating the magnitude of the generated electric energy, which is received from the sensor device 1001. If the magnitude of the generated electric energy is larger than the preset value, the electronic device 1002 (e.g., the processor 910) may terminate the operations without changing the operations performed by the actuator 940. In this case, the actuator 940 may continue to perform the first operation. If the magnitude of the generated electric energy is not larger than the preset value, the electronic device 1002 (e.g., the processor 910) may control the actuator 940 to perform a second operation different from the first operation in operation 1050.

According to an embodiment, the second operation may be the same in kind as the first operation but may have a higher strength than the first operation. For example, the second operation may be a motor's rotation at a higher rotation per minute (RPM) than the first operation. If the magnitude of the generated electric energy is not larger than the preset value, the electronic device 1002 (e.g., the processor 910) may control the actuator 940 to perform a stronger operation than the first operation, allowing the sensor device 1001 positioned in the electronic device 1002 to harvest more energy. According to an embodiment, at least part of the second operation may at least partially differ in kind from the first operation.

FIG. 11A illustrates operations performed by a sensor device and an electronic device according to an embodiment of the disclosure.

FIG. 11B illustrates a relationship between an amount of laundry in a dryer and a cumulative voltage according to an embodiment of the disclosure.

Referring to FIG. 11A, a flow diagram 1100a illustrates operations of the electronic device and the sensor device. In operation 1110a, the electronic device 1102a (e.g., the processor 910) may control the communication module 920 to communicate signals for establishing a communication connection with a sensor device 1101a (e.g., the processor 270c), thereby establishing a communication connection with the sensor device 1101a. According to an embodiment, the electronic device 1102a may be, e.g., a dryer. According to an embodiment, the communication connection between the electronic device 1102a and the sensor device 1101a may be a BLE connection.

In operation 1120a, the electronic device 1102a (e.g., the processor 910) may receive information indicating the magnitude of the generated electric energy from the sensor device 1101a via the communication module 920. According to an embodiment, the information received from the sensor device 1101a may indicate the magnitude of electric energy generated by the sensor device 1101a positioned inside the electronic device 1102a as the actuator (e.g., the actuator 940) of the electronic device 1102a operates. According to an embodiment, the obtained information may be at least one of the current, voltage, or power supplied to the processor 270c (or output from a power conversion circuit).

In operation 1130a, the electronic device 1102a (e.g., the processor 910) may identify an operation routine for the actuator (e.g., the actuator 940) of the electronic device 1102a to process laundry based on the information indicating the magnitude of the generated electric energy received from the sensor device 1101a. According to an embodiment, the operation routine may be identified based on the amount of laundry in the electronic device 1102a which is indicated by the information indicating the magnitude of the generated electric energy. For example, the electronic device 1102a (e.g., the processor 910) may previously store the relationship between the amount of laundry and the increasing speed of the cumulative voltage over time, i.e., the slope of the cumulative voltage over time.

For example, referring to FIG. 11B, as the amount of laundry reduces, the slope of the cumulative voltage over time increases and, as the amount of laundry increases, the slope of the cumulative voltage over time reduces. The electronic device 1102a (e.g., the processor 910) may identify the amount of laundry in the electronic device 1102a based on the information indicating the magnitude of the generated electric energy, received from the sensor device 1101a, and the pre-stored relationship between the amount of laundry and the increasing speed of the cumulative voltage over time.

According to an embodiment, when the electronic device 1102a is a dryer, the operation routine may indicate one or more operations for drying. According to an embodiment, when the electronic device 1102a is a dryer, the operation routine may include at least one of the total operation time, the rotation speed of motor over time during the total operation time, direction of rotation of motor over time, or temperature. According to an embodiment, when the electronic device 1102a is a washer, the operation routine may indicate one or more operations for washing laundry. According to an embodiment, when the electronic device 1102a is a washer, the operation routine may include at least one of the total operation time, or the rotation speed or direction of motor over time during the total operation time.

In operation 1140a, the sensor device 1101a (e.g., the processor 270c) may control the actuator 940 to operate according to the identified operation routine.

In operation 1150a, the sensor device 1101a (e.g., the processor 270c) may receive a sensing value from the sensor (e.g., the sensor 280c) via the communication module (e.g., the communication module 290c) while the actuator 940 is operated according to the identified operation routine.

In operation 1160a, the sensor device 1101a (e.g., the processor 270c) may vary the operation routine of the actuator 940 for processing laundry based on the sensing value received from the sensor (e.g., the sensor 280c) and control the actuator 940 to operate according to the varied operation routine.

In the operations shown in FIG. 11A, since the amount of laundry in the electronic device identified based on the information indicating the magnitude of the generated electric energy, as well as the sensing value received in real-time from the sensor 280c, is considered during the course of identifying the operation routine performed by the actuator 940, the electronic device 1102a (e.g., the processor 910) may control the actuator 940 to perform more efficient and adequate operations.

FIG. 11C illustrates operations performed by a sensor device and an electronic device according to an embodiment of the disclosure.

Referring to FIG. 11C, a flow diagram 1100c illustrates performed by an electronic device and a sensor device. In operation 1110c, the electronic device 1102c (e.g., the processor 910) may control the communication module 920 to communicate signals for establishing a communication connection with a sensor device 1101c (e.g., the processor 270c), thereby establishing a communication connection with the sensor device 1101c. Since the details described above in connection with operation 1110a of FIG. 11A may apply likewise to operation 1110c, no repetitive description is given below.

In operation 1120c, the electronic device 1102a (e.g., the processor 910) may receive a sensing value and information indicating the magnitude of the generated electric energy from the sensor device 1101c via the communication module 920.

In operation 1130c, the electronic device 1102c (e.g., the processor 910) may control the operation of the actuator (e.g., the actuator 940) based on at least one of the sensing value or information indicating the magnitude of the generated electric energy from the sensor device 1101c via the communication module 920. For example, when the electronic device 1102c is a refrigerator, and the sensor device 1101c includes a photoelectric harvester, if the magnitude of electric energy generated by the sensor device 1101c is lower than a predetermined value, the electronic device 1102c (e.g., the processor 910) may increase the output of the internal light of the electronic device 1102c. According to an embodiment, when the electronic device 1102c is a refrigerator and receives a temperature, as the sensing value, from the sensor device 1101c, if the received temperature departs from a predetermined range, the electronic device 1102c (e.g., the processor 910) may control the operation of the cooler until the temperature indicates a value within the predetermined range.

FIG. 12 is a flowchart illustrating operations of an electronic device according to an embodiment of the disclosure.

Referring to FIG. 12, a flowchart 1200 illustrates operations of an electronic device. In operation 1210, a processor (e.g., the processor 910) of an electronic device (e.g., the electronic device 900) may control the actuator 940 to perform a first operation. While the actuator 940 performs the first operation, the processor 910 of the electronic device 900 may identify whether a sensing value and information indicating the magnitude of the generated electric energy is received from a sensor device (e.g., the sensor device 200c) in operation 1220. If the sensing value or information indicating the magnitude of the generated electric energy is received, the sensor device 200c operates properly and thus the method is terminated. When the sensing value and information indicating the magnitude of the generated electric energy are not received, the processor 910 may identify whether a predetermined time elapses in operation 1230. When the predetermined time does not elapse, the processor 910 may perform operation 1220 again. When the predetermined time elapses, the processor 910 may control the actuator 940 to perform a second operation different from the first operation which the actuator 940 used to perform in operation 1240.

According to an embodiment, the second operation may be a stronger operation than the first operation. For example, the second operation may rotate a motor at a higher RPM than the first operation. In the operations of FIG. 12, when the sensing value and information indicating the magnitude of the generated electric energy are not received from the sensor device 200c during the predetermined time while the actuator 940 of the electronic device 900 operates, the processor 910 may control the actuator 940 to perform a stronger operation than the first operation, thereby allowing the sensor device 200c positioned in the electronic device 900 to harvest more energy.

It should be appreciated that various embodiments of the disclosure and the terms used therein are not intended to limit the techniques set forth herein to particular embodiments and that various changes, equivalents, and/or replacements therefor also fall within the scope of the disclosure. The same or similar reference denotations may be used to refer to the same or similar elements throughout the specification and the drawings. It is to be understood that the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. As used herein, the term "A or B," "at least one of A and/or B," "A, B, or C," or "at least one of A, B, and/or C" may include all possible combinations of the enumerated items. As used herein, the terms "first" and "second" may modify various components regardless of importance and/or order and are used to distinguish a component from another without limiting the components. It will be understood that when an element (e.g., a first element) is referred to as being (operatively or communicatively) “coupled with/to,” or “connected with/to” another element (e.g., a second element), it can be coupled or connected with/to the other element directly or via a third element.

As used herein, the term "module" includes a unit configured in hardware, software, or firmware and may interchangeably be used with other terms, e.g., "logic," "logic block," "part," or "circuit." A module may be a single integral part or a minimum unit or part for performing one or more functions. For example, the module may be configured in an application-specific integrated circuit (ASIC).

Various embodiments as set forth herein may be implemented as software (e.g., the program 1340) containing commands that are stored in a machine (e.g., computer)-readable storage medium (e.g., an internal memory 1336) or an external memory 1338. The machine may be a device that may invoke a command stored in the storage medium and may be operated as per the invoked command. The machine may include an electronic device (e.g., the electronic device 101) according to embodiments disclosed herein. When the command is executed by a processor (e.g., the processor 1320), the processor may perform a function corresponding to the command on its own or using other components under the control of the processor. The command may contain a code that is generated or executed by a compiler or an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, the term "non-transitory" simply means that the storage medium does not include a signal and is tangible, but this term does not differentiate between where data is semi-permanently stored in the storage medium and where data is temporarily stored in the storage medium.

According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program products may be traded as commodities between sellers and buyers. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., a compact disc read only memory (CD-ROM)) or online through an application store (e.g., PlaystoreTM). When distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in a storage medium, such as the manufacturer's server, a server of the application store, or a relay server.

According to various embodiments, each component (e.g., a module or program) may be configured of a single or multiple entities, and the various embodiments may exclude some of the above-described sub components or add other sub components. Alternatively or additionally, some components (e.g., modules or programs) may be integrated into a single entity that may then perform the respective (pre-integration) functions of the components in the same or similar manner. According to various embodiments, operations performed by modules, programs, or other components may be carried out sequentially, in parallel, repeatedly, or heuristically, or at least some operations may be executed in a different order or omitted, or other operations may be added.
