Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

The embodiment of the application provides an ultrasonic cleaning method and device, a mobile terminal and a storage medium. The mobile terminal may be a smart phone, a tablet computer, or other devices, and may also be a game device, an AR (Augmented Reality) device, a data storage device, an audio playing device, a video playing device, a wearable device, or other devices, where the wearable device may be a smart band, smart glasses, or other devices.

Referring to fig. 1, fig. 1 is a first schematic flow chart of an ultrasonic cleaning method according to an embodiment of the present application. The ultrasonic processing method provided by the embodiment of the application is applied to an electric mobile terminal, and the mobile terminal comprises an ultrasonic sensor; the ultrasonic cleaning method specifically comprises the following steps:

and 101, the mobile terminal identifies whether the ultrasonic sensor is arranged opposite to the accommodating space of the preset container.

The mobile terminal can identify whether the ultrasonic sensor is arranged opposite to the accommodating space of the preset container or not through the ultrasonic sensor. Specifically, an ultrasonic detection signal can be emitted by the ultrasonic sensor, the ultrasonic detection signal is reflected by an obstacle (such as a preset container) to form a first detection reflection signal, the ultrasonic sensor receives the first detection reflection signal, and the relative position of the preset container and the ultrasonic sensor is determined according to the first detection reflection signal, so that whether the ultrasonic sensor is arranged relative to the accommodating space of the preset container or not is determined.

The mobile terminal can also identify the relative position of the preset container and the mobile terminal through the camera, so as to determine whether the ultrasonic sensor is arranged relative to the accommodating space of the preset container. Wherein, the camera is located same side with ultrasonic sensor. For example, the ultrasonic wave is located at the rear shell of the mobile terminal, and the camera is a rear camera. For another example, the ultrasonic wave is located below the display screen of the mobile terminal, and the camera is a front camera.

The intended container may be a glass container, a plastic container, etc., such as a glass, a glass bowl, a glass dish, a glass kettle, a plastic cup, etc.

It should be noted that, the ultrasonic sensor is disposed opposite to the accommodating space of the preset container, which is to be understood that the ultrasonic sensor is at least partially opposite to the accommodating space of the preset container, or a projection of the bottom of the preset container on the mobile terminal is at least partially overlapped with the ultrasonic sensor.

102, when the ultrasonic sensor is arranged opposite to the accommodating space of the preset container, the mobile terminal identifies whether the preset container has the preset liquid therein.

When recognizing that the ultrasonic sensor is arranged opposite to the accommodating space of the preset container, the mobile terminal recognizes whether the preset container is internally provided with preset liquid or not. The preset liquid can be water or other cleaning liquids. The mobile terminal can identify whether the preset container has the preset liquid or not through the ultrasonic sensor or the camera, and can also determine whether the preset container has the preset liquid or not through the acquired weight. For example, if the mobile terminal is located below the preset container, the mobile terminal has acquired the container weight of the preset container, and the weight acquired by the mobile terminal (the total weight of the preset container and the objects in the preset container) is greater than the container weight, it may be determined that the preset container contains the preset liquid.

103, when the preset liquid in the preset container is identified, the mobile terminal detects whether the preset liquid contains objects to be cleaned.

After the preset liquid in the preset container is identified, the mobile terminal detects whether the preset liquid is filled with the object to be cleaned, and the object to be cleaned can be glasses, a waterproof mobile phone, a waterproof hand, a key and the like, and can also be accessories such as a bracelet, an earring and a necklace. The mobile terminal can determine whether the preset liquid contains objects to be cleaned through the ultrasonic sensor, the camera, the weight sensor, the pressure sensor and the like.

104, when the object to be cleaned in the preset liquid is identified, the mobile terminal drives the ultrasonic sensor with the target driving power to clean the object to be cleaned.

When the object to be cleaned in the preset liquid is identified, the mobile terminal drives the ultrasonic sensor with the target driving power to clean the object to be cleaned. For example, the mobile terminal drives the ultrasonic sensor at the maximum power to clean the object to be cleaned in the preset liquid. The mobile terminal drives the ultrasonic sensor to emit cleaning ultrasonic waves at the maximum power, micro-bubbles exist in liquid after the cleaning ultrasonic waves are vibrated, the micro-bubbles vibrate under the action of the cleaning ultrasonic waves, when sound pressure reaches a certain value, the micro-bubbles grow rapidly and then close, when the micro-bubbles close, shock waves are generated, and thousands of atmospheric pressures are generated around the shock waves. The continuously generated instant high pressure strongly impacts the surface of the object to be cleaned, so that dirt on the surface of the object to be cleaned and in the gap is rapidly peeled off, and the purpose of cleaning the surface of the object to be cleaned and the gap is achieved. The problem of among the correlation technique, ultrasonic cleaning equipment has plug and mains connection, carries and uses inconveniently is solved.

Referring to fig. 2, fig. 2 is a schematic flowchart of a second ultrasonic cleaning method according to an embodiment of the present application. The ultrasonic processing method provided by the embodiment of the application is applied to an electric mobile terminal, and the mobile terminal comprises an ultrasonic sensor; the ultrasonic cleaning method specifically comprises the following steps:

and 201, the mobile terminal identifies whether the ultrasonic sensor is arranged opposite to the accommodating space of the preset container.

202, when the ultrasonic sensor is arranged opposite to the accommodating space of the preset container, the mobile terminal identifies whether the preset container has the preset liquid therein.

And 203, when the preset liquid is identified to be in the preset container, the mobile terminal detects whether the preset liquid contains objects to be cleaned.

204, when the object to be cleaned in the preset liquid is identified, the mobile terminal obtains a second pressure of the preset liquid.

Waterproof mobile terminal can be located the bottom in predetermineeing the container, and the pressure sensor on the mobile terminal can acquire predetermineeing the pressure of predetermineeing the interior liquid of container. Before no object to be cleaned exists in the preset liquid, the mobile terminal acquires a first pressure of the preset liquid. When the object to be cleaned in the preset liquid is identified, the mobile terminal obtains a second pressure of the preset liquid.

A pressure difference is obtained 205 from the first pressure and the second pressure.

Because, increase in the preset liquid of presetting the container and wait to wash the thing after, the water level of presetting liquid can increase, and the pressure that is located the mobile terminal detection of presetting the container bottom and obtains also can increase. The second pressure will be greater than the first pressure, resulting in a pressure difference between the first pressure and the second pressure.

And 206, obtaining the volume of the object to be cleaned according to the pressure difference value and the preset container size.

The mobile terminal can obtain the volume of the object to be cleaned according to the pressure difference value and the size of the preset container. The mobile terminal may acquire the size of the preset container in advance. For example, the preset container is cylindrical, the height value of the water level increase can be obtained through the pressure difference, and the volume of the object to be cleaned can be obtained according to the product of the bottom area of the preset container and the height value.

207, from the plurality of driving powers of the ultrasonic sensor, a corresponding target driving power is determined according to the volume of the object to be cleaned.

The mobile terminal drives the ultrasonic sensor to have a plurality of driving powers with different powers, and corresponding target driving power can be determined from the plurality of driving powers according to the volume of the object to be cleaned. For example, the mobile terminal has a first driving power and a second driving power which are sequentially increased, when the volume of the object to be cleaned is smaller than a preset threshold value, the first driving power is determined as the target driving power, and when the volume of the object to be cleaned is larger than the preset threshold value, the second driving power is determined as the target driving power. The mobile terminal may have a plurality of levels of driving power, for example, the mobile terminal may have 4 levels of driving power, and the 4 levels of driving power correspond to 4 levels of the volume of the object to be cleaned.

In some embodiments, step 204 and step 207 may be replaced by other methods, as follows:

when an object to be cleaned in the preset liquid is identified, acquiring an image of the object to be cleaned;

determining a target cleaning difficulty level according to the image from the plurality of cleaning difficulty levels;

and determining corresponding target driving power according to the target cleaning difficulty level from a plurality of driving powers of the ultrasonic sensor.

The method comprises the steps of obtaining an image of an object to be cleaned through a camera of a mobile terminal, identifying the image through an image identification technology, determining a target cleaning difficulty grade according to the image from a plurality of cleaning difficulty grades, and determining corresponding target driving power according to the target cleaning difficulty grade from a plurality of driving powers of an ultrasonic sensor. For example, if the object to be cleaned is a regular object (e.g. an ophthalmic lens), a lower level of difficulty in cleaning is determined, corresponding to a lower drive power. If the object to be cleaned is an irregular object with more gaps (such as a long bracelet), the object to be cleaned is determined to be in a higher cleaning difficulty grade, and the object to be cleaned corresponds to higher driving power.

when an object to be cleaned in the preset liquid is identified, acquiring the shape of the object to be cleaned according to the ultrasonic sensor;

determining a target cleaning difficulty level according to the shape from a plurality of cleaning difficulty levels;

determining corresponding target driving power according to the target cleaning difficulty level from a plurality of driving powers of the ultrasonic sensor;

the mobile terminal drives the ultrasonic sensor according to the target driving power.

The shape of an object to be cleaned is obtained through an ultrasonic sensor of the mobile terminal, then a target cleaning difficulty grade is determined according to the shape from a plurality of cleaning difficulty grades, and then a corresponding target driving power is determined according to the target cleaning difficulty grade from a plurality of driving powers of the ultrasonic sensor. For example, if the object to be cleaned is a regular object (e.g. a circular spectacle lens), a lower level of difficulty in cleaning is determined, corresponding to a lower drive power. If the object to be cleaned is an irregular object with more gaps (such as a long bracelet with a complex shape), the object to be cleaned is determined to be in a higher cleaning difficulty grade, and the object to be cleaned corresponds to higher driving power.

the method comprises the steps that a mobile terminal obtains a first weight of a preset container and a preset liquid;

when the object to be cleaned in the preset liquid is identified, the mobile terminal obtains a second weight of the preset container, the preset liquid and the object to be cleaned;

obtaining a third weight of the object to be cleaned according to the first weight and the second weight;

a corresponding target drive power is determined from the third weight among the plurality of drive powers of the ultrasonic sensor.

The method comprises the steps that a mobile terminal firstly obtains a first weight of a preset container and preset liquid without objects to be cleaned; then, obtaining a second weight of the preset container, the preset liquid and the object to be cleaned, thereby obtaining a third weight of the object to be cleaned; and finally, determining the corresponding target driving power according to the third weight from the plurality of driving powers of the ultrasonic sensor.

The drive power is determined by the weight of the object to be cleaned, the greater the weight the greater the difficulty to clean. For example, if the items to be cleaned are lightweight items, a lower level of difficulty in cleaning is determined, corresponding to a lower drive power. If the objects to be cleaned are heavy objects, the objects are determined to be in a higher cleaning difficulty grade, and the objects correspond to higher driving power.

In some embodiments, step 207 may be replaced by another method, as follows:

acquiring the shape of an object to be cleaned according to the ultrasonic sensor;

determining a target cleaning difficulty grade according to the size and the shape of an object to be cleaned from a plurality of cleaning difficulty grades;

The shape of an object to be cleaned is obtained through an ultrasonic sensor of the mobile terminal, then a target cleaning difficulty grade is determined according to the shape and the volume from a plurality of cleaning difficulty grades, and then corresponding target driving power is determined according to the target cleaning difficulty grade from a plurality of driving powers of the ultrasonic sensor. For example, if the object to be cleaned is a regular and small-volume item (e.g. a round spectacle lens), a lower level of difficulty in cleaning is determined, corresponding to a lower drive power. If the object to be cleaned is an irregular and bulky object (such as a string of keys), a higher level of difficulty in cleaning is determined, corresponding to a higher driving power.

In some embodiments, the mobile terminal may further determine the cleaning time according to the image, shape and weight of the object to be cleaned, and the more difficult the object to be cleaned is, the longer the cleaning time is.

The mobile terminal drives the ultrasonic sensor according to the target driving power 208.

The mobile terminal drives the ultrasonic sensor with the target driving power to clean the object to be cleaned. Different volumes of the object to be cleaned correspond to different levels of driving power. For example, the mobile terminal drives the ultrasonic sensor with a target driving power to clean the object to be cleaned in a preset liquid. The mobile terminal drives the ultrasonic sensor to send cleaning ultrasonic waves with target driving power, micro-bubbles exist in liquid after the ultrasonic vibration is generated, the micro-bubbles vibrate under the action of the cleaning ultrasonic waves, when sound pressure reaches a certain value, the micro-bubbles grow rapidly and then close, when the micro-bubbles close, shock waves are generated, and thousands of atmospheric pressures are generated around the shock waves. The continuously generated instant high pressure strongly impacts the surface of the object to be cleaned, so that dirt on the surface of the object to be cleaned and in the gap is rapidly peeled off, and the purpose of cleaning the surface of the object to be cleaned and the gap is achieved.

And 209, when the preset container is identified to have no object to be cleaned, turning off or driving the ultrasonic sensor at the lowest driving power.

When the preset container is identified to have no object to be cleaned, the ultrasonic sensor can be turned off, and the ultrasonic sensor can also be driven at the lowest driving power. The ultrasonic sensor driven by the lowest driving power can be used for detecting whether objects to be cleaned enter preset liquid or not in real time, and can also realize other functions such as proximity detection, fingerprint identification and the like.

Referring to fig. 3, fig. 3 is a third schematic flow chart of an ultrasonic cleaning method according to an embodiment of the present application. The ultrasonic processing method provided by the embodiment of the application is applied to an electric mobile terminal, and the mobile terminal comprises an ultrasonic sensor; the ultrasonic cleaning method specifically comprises the following steps:

301, the mobile terminal identifies whether the ultrasonic sensor is disposed opposite to the accommodating space of the preset container.

302, when the ultrasonic sensor is disposed opposite to the accommodating space of the preset container, the mobile terminal identifies whether the preset container has a preset liquid therein.

303, when recognizing that the preset container has the preset liquid therein, the mobile terminal detects whether the preset liquid has the object to be cleaned.

304, when the object to be cleaned in the preset liquid is identified, the mobile terminal obtains a second pressure of the preset liquid.

Waterproof mobile terminal is located the bottom in predetermineeing the container, and the pressure sensor on the mobile terminal can acquire predetermineeing the pressure of liquid in the container. Before no object to be cleaned exists in the preset liquid, the mobile terminal acquires a first pressure of the preset liquid. When the object to be cleaned in the preset liquid is identified, the mobile terminal obtains a second pressure of the preset liquid.

307, determining a corresponding target driving time length according to the volume of the object to be cleaned from a plurality of driving time lengths of the ultrasonic sensor.

The mobile terminal drives the ultrasonic sensor to have a plurality of driving time lengths with different powers, and the corresponding target driving time length can be determined from the plurality of driving time lengths according to the volume of the object to be cleaned. For example, the mobile terminal has a first driving duration and a second driving duration which are sequentially increased, when the volume of the object to be cleaned is smaller than a preset threshold, the first driving duration is determined as the target driving duration, and when the volume of the object to be cleaned is larger than the preset threshold, the second driving duration is determined as the target driving duration. The mobile terminal may have a plurality of levels of driving duration, for example, the mobile terminal has a 4-level driving duration, and the 4-level driving duration corresponds to 4 levels of the volume of the object to be cleaned.

In some embodiments, the

step

304 and 307 may be replaced by other methods, as follows:

and determining a corresponding target driving time length according to the target cleaning difficulty grade from a plurality of driving time lengths of the ultrasonic sensor.

The method comprises the steps of obtaining an image of an object to be cleaned through a camera of a mobile terminal, identifying the image through an image identification technology, determining a target cleaning difficulty grade according to the image from a plurality of cleaning difficulty grades, and determining a corresponding target driving time length according to the target cleaning difficulty grade from a plurality of driving time lengths of an ultrasonic sensor. For example, if the object to be cleaned is a regular object (e.g. an ophthalmic lens), a lower level of difficulty in cleaning is determined, corresponding to a lower actuation time period. If the object to be cleaned is an irregular object with more gaps (such as a long bracelet), a higher cleaning difficulty level is determined, and a higher driving time is corresponded.

In some embodiments, the

step

304 and 307 may be replaced by other methods, as follows:

determining a corresponding target driving time length according to the target cleaning difficulty level from a plurality of driving time lengths of the ultrasonic sensor;

and the mobile terminal drives the ultrasonic sensor according to the target driving duration.

The method comprises the steps of obtaining the shape of an object to be cleaned through an ultrasonic sensor of a mobile terminal, determining a target cleaning difficulty grade according to the shape from a plurality of cleaning difficulty grades, and determining a corresponding target driving time length according to the target cleaning difficulty grade from a plurality of driving time lengths of the ultrasonic sensor. For example, if the object to be cleaned is a regular object (e.g. a circular spectacle lens), a lower cleaning difficulty level is determined, corresponding to a lower actuation time period. If the object to be cleaned is an irregular object with more gaps (such as a long bracelet with a complex shape), the object to be cleaned is determined to be in a higher cleaning difficulty grade, and the object to be cleaned corresponds to a higher driving time.

In some embodiments, the

step

304 and 307 may be replaced by other methods, as follows:

and determining a corresponding target driving time length according to the third weight from the plurality of driving time lengths of the ultrasonic sensor.

The method comprises the steps that a mobile terminal firstly obtains a first weight of a preset container and preset liquid without objects to be cleaned; then, obtaining a second weight of the preset container, the preset liquid and the object to be cleaned, thereby obtaining a third weight of the object to be cleaned; and finally, determining a corresponding target driving time length according to the third weight from a plurality of driving time lengths of the ultrasonic sensor.

The driving time period is determined by the weight of the object to be cleaned, the more the weight, the greater the difficulty to be cleaned. For example, if the items to be cleaned are lightweight items, a lower level of difficulty in cleaning is determined, corresponding to a lower drive time. If the objects to be cleaned are heavy objects, the objects are determined to be in a higher cleaning difficulty grade, and the driving time is longer correspondingly.

In some embodiments, step 207 may be replaced by another method, as follows:

The shape of an object to be cleaned is obtained through an ultrasonic sensor of the mobile terminal, then a target cleaning difficulty grade is determined according to the shape and the volume from a plurality of cleaning difficulty grades, and then a corresponding target driving time length is determined according to the target cleaning difficulty grade from a plurality of driving time lengths of the ultrasonic sensor. For example, if the object to be cleaned is a regular and small-volume item (e.g. a round spectacle lens), a lower cleaning difficulty level is determined, corresponding to a lower drive duration. If the object to be cleaned is an irregular and bulky object (such as a string of keys), a higher level of difficulty in cleaning is determined, corresponding to a higher actuation time.

In some embodiments, the mobile terminal can also determine the target driving power of the ultrasonic sensor according to the image, the shape and the weight of the object to be cleaned, and the more difficult the object to be cleaned is, the larger the target driving power is. For a specific method for determining the target driving power, reference may be made to the above embodiments, and details are not repeated herein.

308, the mobile terminal drives the ultrasonic sensor according to the target driving time length.

The mobile terminal drives the ultrasonic sensor for a target driving duration to clean the object to be cleaned. Different volumes of the object to be cleaned correspond to different levels of drive duration. For example, the mobile terminal drives the ultrasonic sensor for a target driving time period to clean the object to be cleaned in the preset liquid. The mobile terminal drives the ultrasonic sensor to send cleaning ultrasonic wave in a long time with target driving, micro-bubbles exist in liquid after the ultrasonic wave vibration is generated, the micro-bubbles vibrate under the action of the cleaning ultrasonic wave, when sound pressure reaches a certain value, the micro-bubbles grow rapidly and then close, when the micro-bubbles close, shock waves are generated, and thousands of atmospheric pressures are generated around the shock waves. The continuously generated instant high pressure strongly impacts the surface of the object to be cleaned, so that dirt on the surface of the object to be cleaned and in the gap is rapidly peeled off, and the purpose of cleaning the surface of the object to be cleaned and the gap is achieved.

The mobile terminal can drive the ultrasonic sensor with the maximum driving power, and can also drive the ultrasonic sensor by matching the target driving time length with the target driving power.

In some embodiments, the plurality of driving durations and the plurality of driving powers are combined to obtain a plurality of levels, and then the corresponding level is selected according to one or more of an image, a shape, a volume, and a weight of the object to be cleaned, thereby selecting the corresponding driving duration and driving power. For example, the highest level, i.e., the longest driving time period and the largest driving power, is selected to drive the ultrasonic sensor, in which the shape is very complicated or the shape is very complicated and the volume is also very large. The shape is generally complex or the shape is generally complex and the volume is generally large, and the intermediate level, namely, the long driving time and the large driving power are selected to drive the ultrasonic sensor.

And 309, when the preset container is identified to have no object to be cleaned, turning off or driving the ultrasonic sensor at the lowest driving power.

The display screen 10 includes a first substrate layer 11, a display layer 12, a piezoelectric material layer 13, an electrode layer 14, and a second substrate layer 15, which are stacked.

The second substrate layer 15 is provided on one side of the first substrate layer 11. The second substrate layer 15 and the first substrate layer 11 form two substrates, e.g., an upper substrate and a lower substrate, of the display screen 10. The second substrate layer 15 and the first substrate layer 11 provide support and protection for the display layer 12, the piezoelectric material layer 13, and the electrode layer 14.

The first substrate layer 11 may be a glass substrate, for example, and the second substrate layer 15 may be a glass substrate, for example.

The display layer 12 is disposed between the first substrate layer 11 and the second substrate layer 15. The display layer 12 is used for displaying information, such as images, text, etc., thereby implementing the display function of the display screen 10.

The display screen 10 may be a liquid crystal display screen. In this case, the display layer 12 includes liquid crystal, or the display layer 12 is understood to be a liquid crystal layer. The display screen 10 may also be an organic light emitting diode display screen. At this time, the display layer 12 includes an organic light emitting layer, or it is understood that the display layer 12 is an organic light emitting layer.

The layer of piezoelectric material 13 is disposed between the first substrate layer 11 and the second substrate layer 15. The piezoelectric material layer 13 is used to emit an ultrasonic signal.

Referring to fig. 10, fig. 10 is a schematic diagram of a second structure of a display screen in a mobile terminal according to an embodiment of the present application. It is understood that the electrode layer 14 may include a first electrode layer 141 and a second electrode layer 142. Wherein the first electrode layer 141 is disposed between the first substrate layer 11 and the display layer 12, the second electrode layer 142 is disposed between the display layer 12 and the second substrate layer 15, and the piezoelectric material layer 13 is disposed between the display layer 12 and the second electrode layer 142.

It is understood that the positions of the display layer 12 and the piezoelectric material layer 13 in the display screen 10 may be interchanged.

Referring to fig. 11, fig. 11 is a schematic diagram of a third structure of a display screen in a mobile terminal according to an embodiment of the present application. Wherein the first electrode layer 141 is disposed between the first substrate layer 11 and the display layer 12, the second electrode layer 142 is disposed between the display layer 12 and the second substrate layer 15, and the piezoelectric material layer 13 is disposed between the first electrode layer 141 and the display layer 12.

Referring to fig. 12 and 12, fig. 12 is a schematic view of an application scenario of the mobile terminal for performing fingerprint identification according to the embodiment of the present application, and fig. 13 is a schematic view of a principle of performing fingerprint identification by the mobile terminal according to the embodiment of the present application. Wherein, when the user's finger touches or presses on the surface of the mobile terminal (for example, the surface of the display screen), the mobile terminal controls the piezoelectric material layer 21 in the ultrasonic sensor 120 or the piezoelectric material layer 13 in the display screen 10 to emit the ultrasonic signal. When the ultrasonic wave signal contacts with a finger, a reflection signal is generated. The reflected signal is in turn received by the layer of piezoelectric material. And then, the mobile terminal converts the received reflection signal into a corresponding electric signal, and the fingerprint image of the finger of the user can be obtained.

It will be appreciated that the finger surface presents a fingerprint pattern formed by areas of relief. Therefore, when the ultrasonic signals are reflected by different areas of the fingerprint pattern to form reflected signals, the intensity of the reflected signals is different, and the intensity of the reflected signals received by the piezoelectric material layer at different parts of the finger is also different. Therefore, the mobile terminal can acquire the concave-convex degrees of different parts of the finger according to the intensity of the reflected signals of the different parts of the finger, and the three-dimensional fingerprint image of the finger of the user can be formed.

For example, the deepest depressions in the fingerprint pattern may be referred to as fingerprint valleys, and the highest projections in the fingerprint pattern may be referred to as fingerprint ridges. When the user's finger reflects the ultrasonic signal to generate a reflection signal, the intensity of the reflection signal generated by the fingerprint valley is the weakest, and the intensity of the reflection signal generated by the fingerprint ridge is the strongest. The mobile terminal can identify fingerprint valleys and fingerprint ridges on the finger according to the received strength of the reflected signals generated by different parts of the finger.
