When a user is using the device, these millimeter waves are within the radiation range of the human body. If absorbed by the user's body, blood, and bones, they can pose a radiation hazard. Furthermore, when the human body is in the direction of the antenna's radiation, it causes the millimeter waves to diverge, affecting communication quality. Summary of the Invention

[0026] Figure 9 This is a schematic diagram of the structure of a mobile device provided in an embodiment of this disclosure. Detailed Implementation

[0027] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0028] Figure 1 This is a schematic flowchart of a mobile device control method according to an embodiment of the present disclosure.

[0029] This embodiment illustrates the example of a mobile device control method being configured as a control device for a mobile device.

[0030] In this embodiment, the control method for the mobile device can be configured in the control device of the mobile device, and the control device of the mobile device can be set in the mobile device. This embodiment does not limit this.

[0031] This embodiment uses the example of a control method for a mobile device being configured within a mobile device. The mobile device can be a smartphone, tablet, personal digital assistant, wearable device, or other hardware device with various operating systems and imaging capabilities.

[0032] It should be noted that the execution entity of the embodiments disclosed herein may be, for example, a central processing unit (CPU) in a mobile device in terms of hardware, and may be, for example, a related background service in a mobile device in terms of software, without limitation.

[0033] The mobile device screen in this embodiment may specifically be an organic light-emitting diode (OLED) screen, and there is no limitation thereto.

[0034] like Figure 1 As shown, the control method for this mobile device includes:

[0035] S101: Obtain the relative spatial status information between the user and the mobile device.

[0036] In this embodiment of the disclosure, the relative spatial state information between the user and the mobile device is first obtained.

[0037] The mobile device can be, for example, a smartphone, tablet, wearable device, or any other possible mobile device, without limitation.

[0038] Relative spatial state information is used to describe the relative spatial position relationship between the user and the mobile device.

[0039] In some embodiments, during the operation of acquiring the relative spatial state information, the gripping state information and / or relative motion information of the mobile device and the posture information of the mobile device can be acquired. The gripping state information, and / or relative motion information, and posture information are used as the relative spatial state information. That is to say, the gripping state information, relative motion information, posture information, and any other possible relative position information can be referred to as the relative spatial state information.

[0040] Among them, the grip status information is used to describe the grip status of the mobile device, such as whether the mobile device (smartphone) is being held by the user.

[0041] Relative motion information is used to indicate whether the mobile device is moving toward the human body, for example, whether the mobile device is approaching the user's body.

[0042] In practical applications, detecting mobile devices can acquire information about the gripping state and relative motion. In some embodiments, sensors can be embedded in the mobile device to detect the gripping state and proximity state. Such sensors include specific absorption rate sensors (SAR sensors), hereinafter referred to as SAR sensors. Figure 2a This is a schematic diagram of the SAR sensor circuit structure provided in the embodiments of this disclosure, as shown below. Figure 2a As shown, the SAR sensor circuit may include a high-frequency shielding module (RF Shield), a touch sensing module and an analog-to-digital converter module (Cap Sense & ADC), a smart engine module, a power-on reset module (POR), an oscillator (OSC), and a control I2C bus (CTRL & I2C). It is connected to the mobile device (HOST) through clock signal lines (SCL), data signal lines (SDA), and interrupt (NIRQ), and is also connected to wireless communication (cellular) and wireless hotspot (WiFi) through multiple CSIO interfaces (interface 0, interface 1...). The SAR sensor can detect the communication antenna of 5G (Fifth Generation Mobile Communication Technology). All channels and bands are connected to the antenna, and the sensor detection is shielded by ground. A sensor pad is set up, which has a parasitic capacitance Cp to ground. When an object with a certain conductivity, such as a human body, hand, or face, approaches, the electric field radiated by the sensor pad is absorbed by the human body, which is equivalent to a transfer of charge. Therefore, the detection capacitance of the sensor changes. This change in capacitance is converted into a voltage signal through internal capacitance-to-voltage conversion. The voltage signal is collected by an analog-to-digital converter (ADC) to form binary bit information, and then sent to the central processing unit (CPU) of the mobile device through the communication protocol line for processing to obtain the grip status information and relative motion information.

[0043] Generally, SAR sensors can be designed with a rectification / feedback unit (Active Front End, AFE). Figure 2b This is a schematic diagram of the sensor AFE circuit structure provided in the embodiments of this disclosure, as shown below. Figure 2bAs shown, the rectification / feedback unit mainly includes an offset compensation module, a shield control module, an analog-to-digital converter (ADC) module, and a current-to-voltage (C-to-V) module. When a finger, palm, or face is near the sensor, the sensor feeds back a signal to the C-to-V module. The shield control module can also control the shield to reduce interference. Furthermore, the SAR sensor can also be designed with circuit modules such as an analog-to-digital converter (ADC), an oscillator circuit module (OSC), a communication module, and a power supply module.

[0044] Furthermore, a single SAR sensor on a mobile device can be configured with a single channel, or multiple channels can be configured for a single SAR sensor, or multiple sensor channels can be configured for multiple SAR sensors. Moreover, in the case of multiple SAR sensors, multiple sensor pads and sensor channels can be placed at different locations on the mobile device to detect grip status information and relative motion information at different locations on the mobile device, without any restrictions.

[0045] In a specific instance Figure 3 This is a schematic diagram of the radiation adjustment structure of a mobile device according to an embodiment of this disclosure, such as... Figure 3 As shown, a mobile device can be equipped with multiple SAR sensors, such as electromagnetic wave sensor 1 (Sar1 sensor) and electromagnetic wave sensor 2 (Sar2 sensor), hereinafter referred to as Sar1 and Sar2. The gripping state information and relative motion information can be detected through Sar1 and Sar2.

[0046] Attitude information, used to describe the attitude of a mobile device, such as the device's gravitational acceleration and angular velocity, is not subject to any restrictions.

[0047] In some embodiments, attitude sensors may be used to detect the attitude information of the mobile device, such as MEMS-based sensors; or attitude information may be acquired in any other possible manner, without limitation.

[0048] S102: Determine antenna configuration information based on relative spatial state information.

[0049] After obtaining relative spatial state information such as holding state, relative motion state, and attitude information, the antenna configuration information is further determined based on the relative spatial state information.

[0050] The antenna configuration information indicates the antenna configuration that the mobile device can use under its current holding state, relative motion, and posture.

[0051] In some embodiments, antenna configuration information may include: the number of target antennas, and / or the antenna layout location, and / or the target radiation direction.

[0052] In the context of the current holding state, relative motion state, and posture, the number of antennas used by the mobile device for communication can be referred to as the number of target antennas. The installation position of the target antenna in the mobile device is called the antenna layout position. The radiation direction of the target antenna can be referred to as the target radiation direction. Generally, the target radiation direction points away from the human body.

[0053] In other words, for communication in any holding state, relative motion state, and posture, the mobile device can determine antenna configuration information such as the target antenna, the target antenna layout position, and the radiation direction of the target antenna. Therefore, the antenna configuration information can include a variety of data, which is beneficial for subsequent rational antenna configuration.

[0054] For example, attitude data algorithms can be used to calculate the holding state information, relative motion information, and attitude information to determine the antenna configuration information. The attitude data algorithm can be any algorithm, and there are no restrictions on it.

[0055] Some embodiments, such as Figure 3 As shown, the attitude data algorithm can run in the microcontroller unit (MCU) of a mobile device. The MCU calls the attitude data algorithm to calculate the antenna configuration information based on the grip state information and relative motion information detected by the SAR sensor, as well as the attitude information detected by the attitude sensor. Alternatively, the attitude data algorithm can also run in the sensor core of the electronic processing unit (AP). The sensor core uses the attitude data algorithm to calculate the antenna configuration information based on the grip state information, relative motion information, and attitude information. There are no restrictions on which one is used.

[0056] S103: Configure the antenna array in the mobile device according to the antenna configuration information.

[0057] Mobile devices can be equipped with one or more antenna arrays, for example, m*n antenna arrays. The multiple antennas included in the m*n antenna arrays can be referred to as alternative antennas.

[0058] In some embodiments, the target number of antennas can be selected from multiple candidate antennas as target candidate antennas based on antenna configuration information, and the layout position of the target candidate antennas satisfies the antenna layout position.

[0059] In other words, one or more antennas that meet the target antenna quantity and antenna layout requirements are selected from multiple candidate antennas as the target candidate antennas.

[0060] For example, such as Figure 3 As shown, the upper half of the mobile device is equipped with antenna array 1, and the lower half is equipped with antenna array 2. Antenna array 1 and antenna array 2 are connected to a transceiver. Antenna array 1 and antenna array 2 can be, for example, a 4x4 antenna array. Antenna configuration information, for example, if the target number of antennas is 4 and the antenna layout is in the upper half of the mobile device, then 4 antennas are selected from antenna array 1 in the upper half of the mobile device as target candidate antennas. In practical applications, to make the electromagnetic wave field radiation direction of the multi-transmitted signals more concentrated and directional, antennas that are close to each other can be selected from antenna array 1 as target candidate antennas. For example, the 4 central antennas can be selected from the 4x4 antenna array 1 as target candidate antennas, thereby making the radiation more concentrated and the power density higher; alternatively, the antenna configuration information can also indicate specific antennas as target candidate antennas, without limitation. Furthermore, in the design process of mobile devices, it is preferable to use antenna arrays with a large number of antennas to make the radiation more concentrated and the power density higher.

[0061] Furthermore, the current radiation direction of the target candidate antenna is adjusted to the target radiation direction. That is to say, the radiation direction of the antenna is adjusted according to the target radiation direction in the antenna configuration information. For example, by adjusting the phase of the antenna, the radiation direction is adjusted to avoid the human body.

[0062] In this embodiment of the disclosure, by acquiring the relative spatial state information of the user and the mobile device, determining the antenna configuration information based on the relative spatial state information, and configuring the antenna array in the mobile device accordingly based on the antenna configuration information, the radiation hazards of millimeter waves generated by antenna communication to the human body can be reduced, and the communication quality can be improved and the communication power reduced, thereby improving the control effect of the mobile device.

[0063] Figure 4 This is a flowchart illustrating a mobile device control method according to another embodiment of this disclosure, as shown below. Figure 4 As shown, the control method for this mobile device includes:

[0064] S401: Obtain status information on whether the mobile device is being held. When the status information indicates that the mobile device is being held, obtain the location information of the area where the mobile device is being held. The status information and the location information are used together as the holding status information.

[0065] In this embodiment, a single SAR sensor can be used to detect the mobile device to obtain information about whether the mobile device is being held, i.e., whether the mobile device is being held by a person's hand. Alternatively, the mobile device can be equipped with multiple SAR sensors, and the value changes sensed by the capacitance values ​​of multiple SAR sensors (e.g., SAR1 and SAR2) can be used to determine whether it is being held with one hand or two hands.

[0066] Furthermore, once it is determined that the mobile device is being held, it is also possible to detect the location information of the area where the mobile device is being held, that is, to detect the location where it is being held.

[0067] In some embodiments, the capacitive sensor pad of sar1 can be designed in the upper half of the mobile device, and the capacitive sensor pad of sar2 can be designed in the lower half of the mobile device. Based on the capacitance values ​​of sar1 and sar2, the location information of the area where the mobile device is held can be determined, such as: the upper half is held, or the lower half is held, or the upper half and the lower half are held at the same time.

[0068] In other embodiments, sar1 and sar2 may each have a capacitive sensor pad and a sensor channel in the upper and lower halves of the mobile device, respectively. Based on the capacitance values ​​of each sar1 in the upper and lower halves, the status information of whether it is being held and the area location information are determined.

[0069] S402: Acquire information on the relative distance change and relative motion direction between human skin and mobile device, and use the relative distance change and relative motion direction as relative motion information.

[0070] Among them, the relative distance change information is used to describe the change in distance between human skin and mobile device, and can be represented by d.

[0071] The relative direction of motion is used to describe the direction of motion between human skin and mobile device, such as: human skin moving towards the mobile device, or human skin moving away from the mobile device.

[0072] Figure 5a This is a schematic diagram of the internal SAR circuit design of a mobile device provided in an embodiment of this disclosure, wherein SAR1 and SAR2 communicate with the mobile device (Host); Figure 5bThis is a schematic diagram of the sensor pad structure provided in the embodiments of this disclosure, including a side view and a top view, as shown below. Figure 5b As shown, the sensor structure includes an overlay and a printed circuit board dielectric. Figure 5c This is a schematic diagram of capacitance change when a living object approaches, provided in an embodiment of this disclosure. Figures 5a-5c As shown, electric field lines are distributed around the sensor. Multiple SAR sensors (e.g., SAR1 and SAR2) can be designed inside a mobile device. Each SAR sensor can use multiple sensor pads and sensor channels to achieve proximity detection at multiple locations. Figure 5b and Figure 5c As shown, each sensor pad has a parasitic capacitance Cp = Cenv from the environment, as well as a capacitance Cuser changed by the user's finger. The sensor pad has a certain electric field in space, and its electric field lines diverge in space. When human skin (such as fingers) moves towards the mobile device, some of the electric field lines are attracted by the fingers, thereby changing the capacitance Cuser between the sensor pad and the ground. Figure 2b The circuit shown is an amplified version of the Cuser change section. Internally, it uses a differential operational amplifier circuit. Based on the change in the capacitance value Cuser, the relative distance change between the human skin and the mobile device can be determined, i.e., the distance d between the human skin and the mobile device. Therefore, this embodiment can determine the relative movement direction and relative distance between the human skin and the mobile device simply by observing the change in capacitance value, thus enabling rapid proximity detection and improving the speed of detecting relative motion information.

[0073] S403: Obtain the gravitational acceleration corresponding to the mobile device.

[0074] For example, a MEMS-based accelerometer can be used to detect the mobile device to obtain its gravitational acceleration g, or other methods can be used to detect this gravitational acceleration without limitation.

[0075] S404: Determine multiple acceleration components corresponding to gravitational acceleration. These multiple acceleration components correspond to multiple coordinate axes. Any two coordinate axes constitute a corresponding coordinate plane. These multiple coordinate planes constitute the target coordinate system.

[0076] For example, an accelerometer could be an accelerometer triaxial sensor. Gravitational acceleration has three acceleration components along the accelerometer triaxial axis, which can be represented as Gx, Gy, and Gz. These three acceleration components correspond to the x, y, and z coordinate axes. Any two of these axes can form a coordinate plane, such as the xoy plane, yoz plane, and zox plane. These planes together constitute the target coordinate system.

[0077] S405: Determine the acceleration plane vector in the corresponding coordinate axis plane based on any two coordinate axes. That is, determine the acceleration plane vector in the xoy plane based on the acceleration components of the x-axis and y-axis, determine the acceleration plane vector in the yoz plane based on the acceleration components of the y-axis and z-axis, determine the acceleration plane vector in the zox plane based on the acceleration components of the x-axis and z-axis, and the superposition of multiple acceleration plane vectors is the gravitational acceleration g of the mobile device.

[0078] S406: Obtain multiple angle information corresponding to multiple acceleration plane vectors respectively.

[0079] For example, multiple angle information can be the supplementary angle between the gravitational acceleration g and the cosine angle of the xoy, yoz, zox coordinate axis plane mentioned above, or it can be any other possible angle information, without any restrictions.

[0080] S407: Based on multiple angle information, determine a first direction of the mobile device relative to human skin and a second direction of the top of the mobile device. The first and second directions are used together as attitude information.

[0081] The direction of the mobile device relative to the human skin can be referred to as the first direction. For example, the front of the mobile device may face the human skin, or the back of the mobile device may face the human skin.

[0082] The second direction describes the orientation of the top of the mobile device; for example, the second direction indicates that the top of the mobile device is facing up, or that the top of the mobile device is facing down.

[0083] Therefore, this embodiment can use the orientation of the mobile device relative to the human skin and the orientation of the top of the mobile device as attitude information, thus reflecting a more comprehensive attitude. Furthermore, in determining the attitude information, the gravitational acceleration is first determined, then the acceleration plane vector is determined, followed by the angle information, and finally the attitude information is determined based on the angle information. Therefore, the attitude information of the mobile device can be calculated step by step, improving the accuracy of the attitude information.

[0084] S408: Determine antenna configuration information based on relative spatial state information.

[0085] S409: Configure the antenna array in the mobile device according to the antenna configuration information.

[0086] For a detailed description of S408-S409, please refer to the above embodiments, and they will not be repeated here.

[0087] This embodiment of the invention, by acquiring the relative spatial state information between the user and the mobile device, determining antenna configuration information based on this information, and configuring the antenna array in the mobile device accordingly, can reduce the radiation hazards of millimeter waves generated by antenna communication to the human body, improve communication quality, reduce communication power, and thus enhance the control effect of the mobile device. Furthermore, this embodiment can determine the relative motion direction and relative distance between the human skin and the mobile device simply by observing changes in capacitance, thereby enabling rapid proximity detection and improving the speed of detecting relative motion information. Moreover, this embodiment can use the direction of the mobile device relative to the human skin and the direction of the top of the mobile device as attitude information, thus reflecting a more comprehensive attitude. In determining the attitude information, the gravitational acceleration is first determined, then the acceleration plane vector is determined, followed by the angle information, and finally the attitude information is determined based on the angle information. Therefore, the attitude information of the mobile device can be calculated step by step, improving the accuracy of the attitude information.

[0088] Figure 6 This is a flowchart illustrating a mobile device control method according to another embodiment of this disclosure, as shown below. Figure 6 As shown, the control method for this mobile device includes:

[0089] S601: Obtain the relative spatial status information between the user and the mobile device.

[0090] For a detailed description of S601, please refer to the above embodiments, which will not be repeated here.

[0091] S602: Obtain the usage status information of the mobile device.

[0092] In this embodiment, the usage status information of the mobile device can also be obtained, such as whether the mobile device is in a call state.

[0093] S603: Determine antenna configuration information based on relative spatial state information and usage state information.

[0094] In other words, based on the information of whether it is being held, the location of the area being held, the relative distance change, the relative direction of movement, the first direction, the second direction, and the status information, the number of target antennas, and / or the antenna layout location, and / or the target radiation direction are determined.

[0095] In some embodiments, reference location information for the unheld area can be determined first based on the area location information. For example, if the lower half of the mobile device is not held, then the lower half of the mobile device is used as the reference location information.

[0096] Furthermore, based on the relative distance change information and relative motion direction, the target location information that does not correspond to human skin is determined from the reference location information, and the location indicated by this target location information is used as the antenna layout location. That is, the number of configurable antennas in the antenna array installed at the target location is used as the target antenna number. Further, based on the first and second directions, the direction avoiding the direction pointing towards human skin is used as the target radiation direction. Therefore, this embodiment can also refer to the usage status of the mobile device during the determination of antenna configuration information, thus ensuring that the mobile device can reduce the harm of radiation to the human body during use and improve communication quality.

[0097] In some embodiments, if status information indicates that a call is in progress, the target radiation direction is avoided from the direction pointing towards the ear. That is, adjusting the target antenna to radiate in a direction other than the ear reduces the back lobe power of the antenna radiation and minimizes the harmful effects of radiation on the human body. Furthermore, radiating in a direction other than the ear reduces the body's obstruction of the radiation direction, thus enhancing communication quality.

[0098] In other embodiments, the mobile device's display screen can be a foldable screen. Generally, foldable mobile devices have antenna array transmitters on both sides (front and back). In this case, if the usage status information indicates that the user is currently in a call, the current usage plane is determined, for example, the current usage plane is the front. Furthermore, the target radiation direction is chosen as the direction that the alternative antennas configured on the current usage plane (front) can face, avoiding the direction pointing towards the user's ear. This reduces the harmful effects of antenna radiation on the human body and enhances communication quality even for foldable mobile devices.

[0099] It is understood that the technical solution of this embodiment can be applied not only to foldable screen mobile devices, but also to rollable screen and other possible forms of mobile devices, without limitation.

[0100] In addition to holding the mobile device in one's hand or bringing one's face close to the mobile device, when the mobile device is close to the body while wearing clothing, such as when the mobile device is placed in a pocket, the system can detect whether the top or bottom of the mobile device is facing down. By adjusting the phase of the antenna array on the top part of the mobile device, the radiation direction is directed away from the skin, thereby enhancing communication quality and reducing the harmful effects of radiation on the human body.

[0101] S604: Configure the antenna array in the mobile device according to the antenna configuration information.

[0102] For a detailed description of S604, please refer to the above embodiments, which will not be repeated here.

[0103] This embodiment of the invention, by acquiring the relative spatial state information of the user and the mobile device, determining antenna configuration information based on the relative spatial state information, and configuring the antenna array in the mobile device accordingly, can reduce the radiation hazards of millimeter waves generated by antenna communication to the human body, improve communication quality, reduce communication power, and thus enhance the control effect of the mobile device. Furthermore, this embodiment can also consider the usage status of the mobile device during the determination of antenna configuration information, thus ensuring that the mobile device can reduce radiation hazards to the human body and improve communication quality during use. Moreover, this invention can achieve the effect of reducing antenna radiation hazards to the human body and enhancing communication quality for mobile devices with screens of any shape.
