Abstract
Description
[Technical Field]
[0001] The present invention relates to devices and systems for determining properties of an object, and more particularly to devices and systems that use at least the amplitude and frequency of broadband sound signals emitted by the device. [Background technology]
[0002] In recent years, the demand for detecting the location, movement, or other properties of one or more objects has been continuously increasing. For example, the Internet of Things (IoT) has seen explosive growth in many applications. To name a few, the demand for automated warehousing, automated logistics, and intelligent fitness equipment is continuously growing.
[0003] Typically, to date, detectors placed on an object to detect one or more properties of the object have used one or more of the following technologies: gyroscopes, motion detectors, multi-axis detectors, Hall elements, piezoelectrics, magnetometers, imaging optics, infrared elements, other fixed electronic elements, and the like. Additionally, such detectors often transmit signals of the detected property or properties using Bluetooth, Wi-Fi, other wireless chips, or cable lines. Summary of the Invention [Problem to be solved by the invention]
[0004] However, all of these currently available detectors are limited by the drawbacks discussed below. (1) The number of channels for wireless connections, such as those provided by Bluetooth and Wi-Fi, is limited, often limiting the connection between a detector and a corresponding analytical device, especially when the analytical device is further connected to one or more other detectors or one or more other devices. (2) The hardware cost and energy consumption of such detectors. (3) Sensitivity, reliability, complexity of corresponding algorithm, limited signal transmission distance, and low spatial flexibility of cable lines.
[0005] Clearly, new techniques need to be developed to better detect one or more properties of one or more objects distributed within a space.
[0006] The present invention was developed in light of the above-mentioned problems and is based on the inventor's extensive research. Its objective is to provide a detection device and a determination system for determining the position, movement, or other properties of one or more objects distributed in space. In this determination system, several detection devices are attached to several objects separated from each other, respectively, and the detected properties of the one or more objects are transmitted to an analysis device in the form of a wide-frequency sound signal (e.g., an audio signal or an ultrasonic signal) and analyzed. The analysis device may be a smartphone, tablet, laptop, or the like with a relevant application program installed. Each detection device includes at least a trigger module and a sound module, the former configured to detect one or more properties of the object to which the detection device is attached, and the latter configured to transmit a broadband sound signal based on the detection result of the trigger module. In this way, if a property of the object has a specific value, the trigger module attached to the object detects and transmits a message to the sound module, which then transmits a corresponding broadband sound signal to the corresponding analysis device. The property of the object is determined by analyzing the received signal transmitted from the sound module.
[0007] Generally, many embodiments of the present invention use a crystal oscillator to simply and efficiently provide the required broadband sound signal. Using a single crystal oscillator to provide a single vibration signal offers the advantage of integrating the trigger module, crystal oscillator module, and sound module into a single circuit. In this way, when the detected object property has a first value, the trigger module is triggered and electrically connected to the crystal oscillator module and sound module, thereby converting the vibration signal into a broadband sound signal. Conversely, when the object property is not detected or is detected to have another value, the driver is not driven and is electrically isolated from the crystal oscillator module and sound module, resulting in no broadband sound signal being converted into a vibration signal.
[0008] The use of a crystal oscillator has at least the following advantages: (1) Flexible selection of many conventional commercial products. (2) It is low cost, consumes little energy, and is easy to operate. (3) The generated vibration signal can be easily converted into a broadband sound signal. Furthermore, the use of broadband sound signals has at least the following advantages. (1) It does not conflict with currently widely used Bluetooth, Wi-Fi and / or other wireless communication technologies. (2) By adjusting the frequencies of the different broadband sound signals transmitted by different detectors, mutual interference can be reduced. (3) It is low cost, consumes little energy, and is easy to operate.
[0009] It should be noted that the broadband sound signal transmitted to a distant sound module differs from the broadband sound signal received by the analyzer because, due to the Doppler effect, the frequency of the signal transmitted to the distant sound module is inversely proportional to the speed of movement between the two modules and the square of the amplitude of the signal. Reasonably, the changes in frequency and amplitude of the broadband sound signal can be used to determine the relative motion and distance between the analyzer and the detector.
[0010] In addition, the trigger module may be activated in a variety of ways, for example, using different hardware in different embodiments to detect the value of a property and work in conjunction with the sound module. For example, a thermistor may be used to detect the temperature of an object, and the sound module may transmit a signal related to the object's temperature based on the detected temperature. For example, a magnet may be used to detect whether an object is locked with a magnetic button, and the sound module may convert this message to notify an analysis device of the object's status. For example, in some embodiments, the trigger module may be triggered when different values of a property are measured at different times, allowing the sound module to convert different vibration signals provided by different crystal oscillators. For example, in some embodiments, the trigger module may be configured to be continuously or not continuously triggered, thereby fixing a broadband sound signal transmitted from a remote sound module, and changes in the amplitude and / or frequency of the received broadband sound signal may be used to analyze the object's position and / or movement.

[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the following embodiments and may take various forms as long as they fall within the technical scope of the present disclosure.
[0014] The present invention provides a detection device and a determination device for detecting one or more properties of one or more objects distributed in a space. For example, an electrochemical detector for detecting volatile organic compounds, a humidity detector, a gas detector, etc., can be used to detect the position, movement direction, movement speed, or temperature of one or more objects distributed in a space. The determination system attaches one or more detection devices to one or more objects, respectively, to generate and transmit one or more broadband sound signals corresponding to one or more properties of the objects, and applies an analysis device (e.g., a smartphone, tablet, laptop, or other device capable of executing an application program) to receive and analyze the broadband sound signals, thereby understanding one or more properties of each of the objects. Figure 1A is a schematic diagram showing the relationship between the determination system 100 of the present invention and a detection device 101, and also shows the analysis device 102. Similarly, FIG. 1B is a schematic diagram showing how a determination system 100 with multiple detection devices 101 detects multiple objects 103 that may or may not be similar to one another, where one detection device 101 may not be used to detect one or more properties of one object, but rather to detect one or more properties (e.g., temperature) of a location in this space, as shown in the top right corner of FIG. 1B.
[0015] One key feature of the present invention is apparent when compared with the aforementioned currently available detectors. Clearly, the use of broadband sound signals is a key feature of the present invention, regardless of whether the broadband sound signals are audio signals audible to humans or inaudible ultrasonic signals, and regardless of the specific frequency of the broadband sound signals, e.g., 18-22 KHz or 24-48 KHz, commercial applications for smart fitness equipment and the like are possible. A key advantage of using broadband sound signals is that they are not limited by the limited number of channels available with Bluetooth, Wi-Fi, or other currently available wireless communications. In particular, when the analytical device is a smartphone, laptop, and / or tablet device that typically communicates with other devices using wireless channels such as Bluetooth and / or Wi-Fi, the use of broadband sound signals prevents other commercial products from competing for wireless communication channels with the analytical device. Note that because the detectors are only used to transmit messages related to the position, movement, and / or temperature or other properties of the object to which they are attached, and not to transmit music, photos, movies, or other large file contents, the frequency bandwidth required for each detector is not large. Incidentally, an analytical device can easily communicate with multiple detectors using receivers that receive different sound signals having different frequencies within a wide frequency range. This increases the number of detectors that an analytical device can communicate with compared to the number of detectors that can communicate with each other when using Wi-Fi, Bluetooth, or other currently available wireless communications, and also avoids mutual interference when detectors communicate with other devices via Wi-Fi, Bluetooth, or other currently available wireless communications.
[0016] The main advantage of using broadband sound signals is that there are many commercially available products and technologies available today. Therefore, the advantage of using broadband sound signals is that they can be implemented efficiently and without significant technical and / or cost difficulties. By arranging different detectors 101, different broadband sound signals having different frequencies can be transmitted, allowing the analyzer 102 to efficiently distinguish between the different signals from the detectors 101. Even if the detectors 101 are attached to different objects far away from each other, and even if the detectors 101 are not far apart, two or more detectors 101 can transmit separate broadband sound signals having the same frequency, as long as the crosstalk and / or interference between the signals is acceptable.
[0017] Furthermore, the structure of the detection device 200 basically includes a trigger module 201 and a sound module 202 (see FIG. 2A), and further includes a crystal oscillator module 203 (see FIG. 2B), which typically includes one or more crystal oscillators. The trigger module 201 is configured to generate a detection signal based on one or more properties of the attached object (or based on one or more properties of the location of the detection device 200 under certain specific circumstances), and the sound module 202 is configured to generate and transmit a broadband sound signal based on the detection signal (or the trigger device of the trigger module 201). In brief, when the detection module 201 detects that the value of a specific property of the attached object exceeds a critical value, for example, if the tilt angle of the attached object's horizontal axis is greater than a specific angle, the trigger module 201 sets the value of the detection signal to 1 or a first specific value and notifies the sound module 202 to generate and transmit a corresponding broadband sound signal. Alternatively, when the trigger module 201 sets the value of the detection signal to 0 or a second specific value, it notifies the sound module 202 that it does not need to generate and transmit any broadband sound signal, or that it needs to generate and transmit another broadband sound signal corresponding to the second specific value. In short, based on the values of one or more properties of the attached member in determining, the detection device 200 may not generate and transmit any broadband sound signal, or may generate and transmit a different broadband sound signal having a different value.
[0018] Incidentally, if broadband sound signals are used instead of Wi-Fi, Bluetooth, or other wireless communications, the present invention does not necessarily limit how the sound module 202 generates the broadband sound signal based on the trigger status of the trigger module 201. In other words, any known, developing, and / or future technology can be applied to generate and transmit the required broadband sound signal in the present invention. That is, using a crystal oscillator is a simple and low-cost method because all crystal oscillators provide particularly high-precision vibration signals. In this way, the trigger module 201, the crystal oscillator module 203, and the sound module 202 jointly form a circuit. When the trigger module 201 is triggered, both the detection signal and the vibration signal generated by the crystal oscillator module 203 are transmitted to the sound module 202 and used to generate the broadband sound signal. In contrast, when the trigger module 201 is not triggered, neither the detection signal nor the vibration signal generated by the crystal oscillator module 203 are transmitted to the sound module 202, and no corresponding broadband sound signal is generated. In this way, each crystal oscillator generates a separate vibration signal, and the vibration signal generated by the crystal oscillator module 203 is electrically connected to the trigger module 201 and the sound module 202 by at least one or more portions of the crystal oscillator. Therefore, by using the crystal oscillator module 203 having one or more crystal oscillators and controllably adjusting the operation of the crystal oscillator module 203, the vibration signal output by the crystal oscillator module 203 can be used to generate a broadband sound signal. For example, the output vibration signal may be adjusted to have a frequency of 20 KHz, and the sound module 202 may have a horn diaphragm to convert the vibration signal into an ultrasonic signal having a frequency of 20 KHz.For example, the output vibration signal is adjusted to have a frequency of 5 KHz, the detection signal has three such values, and the sound module 202 has a mixing circuit and a horn diaphragm, which mixes the vibration signal and the detection signal and converts them into an ultrasonic signal with a frequency of 15 KHz. Of course, in some situations, the frequency of the broadband sound signal is fixed and is not based on the operation of the trigger module 201. For example, when the trigger module 201 corresponding to a certain special object is triggered at any time, the broadband sound signal is continuously emitted, that is, the analysis device of the determination system continuously monitors this special object.
[0019] Furthermore, there is no need to limit the specific details of the trigger module 201. In fact, depending on which property of the attached material is desired to be detected, different types of trigger modules 201 may be used to detect the same property. As an example, Figures 3A-3I are schematic diagrams each showing several useful types of trigger modules 201.
[0020] In the situation shown in Figure 3A, the trigger module 301 includes a thermistor, the detection signal is related to the temperature detected by the thermistor, and the sound module 302 includes an ultrasonic sensor. Reasonably, as the detected temperature (e.g., the temperature of the attached object) decreases, the electrical resistance increases, and the amplitude of the ultrasonic signal (or the amplitude of the broadband sound signal) decreases accordingly, and vice versa. Therefore, the vibration signal within the sound module 302 is considered to be fixed, and the output ultrasonic signal is also considered to be determined by both the internal vibration signal and the detection signal, which changes according to the change in temperature detected by the thermistor. Obviously, in this situation, the trigger module is continuously triggered, and the output detection signal is continuously modified.
[0021] 3B, the trigger module 301 includes a conductive ball 3011 (e.g., a metal ball) located inside the conduit 3012, and the detection signal is related to the tilt angle detected by the conductive ball 3011 located inside the conduit 3012. Obviously, the conductive wires 304 of other components 305 (including but not limited to the sound module 302) electrically connected to the detection device 300 are also electrically connected to different parts of the conduit 3012, and the trigger module 301 and the other components 305 form a closed circuit when the conductive ball 3011 is located at the right end of the conduit 3012, but form an open circuit when the conductive ball 3011 is located at other parts of the conduit 3012. As a result, the trigger module 301 is triggered when the conductive ball 3011 is not rolling at the right end of the remote conductor 3012, i.e., the trigger module 301 is used to detect the inclination of the object to which the detection device 300 is attached along the axial direction of the pipeline 3012.
[0022] In the situation shown in FIG. 3C, the trigger module 301 includes a mercury switch 3013, and the detection signal is related to the tilt angle detected by the mercury switch. The mercury switch 3013 is a known commercial product, and measures tilt angle and / or deformation based on which of several conductive parts of the container a drop of mercury stored inside contacts. Therefore, specific details of the mercury switch 3013 can be omitted. Two conductive parts of the container of the mercury switch 3013 are electrically connected to other components 305 of the detection device 300 (including, but not limited to, the sound module) via conductors 304. This determines whether the tilt angle of the mercury switch 3013 forms a closed circuit or an open circuit, and the trigger module 301 is used to detect the tilt angle of the object to which the detection device 300 is attached in the direction of the two conductive parts connected to the container of the mercury switch 3013.
[0023] In the situation shown in FIG. 3D , the trigger module 301 includes a Hall effect switch 3014, and the detection signal is related to the magnetic field detected by the Hall effect switch 3014. The Hall effect switch 3014 is a known commercial product, and determines whether to turn on or off based on the strength of the detected magnetic field. Therefore, specific details of the Hall effect switch 3014 are omitted. The on and off positions of the Hall effect switch 3014 are electrically connected using wires 304 to different parts 305 of the detection device 300 (including, but not limited to, the sound module), and the magnetic field detected by the Hall effect switch 3014 is used to determine whether to form a closed circuit or an open circuit, and the trigger module 301 is used to detect the magnetic field of the object to which the detection device 300 is attached or the magnetic field at the location of the detection device 300.
[0024] In the situation shown in Figure 3E, the trigger module 301 includes a spring switch 3015, and the detection signal is related to the movement measured by the spring switch 3015. One end of the spring switch 3015 is fixed and electrically connected to another component 305 of the detection device 300 (including, but not limited to, the sound module) via a conductor 304. The other end is free and is adjacent to another conductor 304 that is electrically connected to another component 305 of the detection device 300. Thus, when the spring switch 3015 swings along a certain direction and the swing width is greater than a certain width threshold, the spring switch 3015 simultaneously contacts all of the conductors 304 and forms a closed circuit. However, when the swing width of the spring switch 3015 along these certain directions is smaller than the width threshold or when the spring switch 3015 swings along another certain direction, the spring switch 3015 does not simultaneously contact all of the conductors 304 and forms an open circuit. That is, by using the spring switch 3015, the detection device 300 detects whether the width of the object attached thereto in a certain direction is greater than a certain width threshold value.
[0025] In the situation shown in Fig. 3F, the trigger module 301 includes a ball 3016 located inside a combination of a transmission conduit 3017 and an insulating tube 3018, and the detection signal is determined by whether the ball 3016 enters the transmission conduit 3017 or the insulating tube 3018. Logically, this situation is a variation of the situation shown in Fig. 3A, and is used to detect the tilt of an object attached to the detection device 300 along the axis of these conduits 3017 / 3018. Here, two conductors 304 are connected to two opposite ends of the transmission conduit 3017 and are also connected to other components 305 of the detection device 300 (including, but not limited to, a sound module), and whether a closed circuit or an open circuit is formed is determined by how the ball 3016 moves.
[0026] In the situation shown in Figure 3G, the trigger module 301 includes a ball 3016 located inside a combination of multiple transmission conduits 3017 and multiple insulating tubes 3018, and the detection signal is determined by which transmission conduit 3017 the ball 3016 enters. Reasonably, this situation is a further variation of the situation shown in Figure 3F, and is used to more accurately and flexibly detect the inclination of an object attached to the detection device 300 along the axial direction of these conduits 3017 / 3018. Here, two conductive wires 304 are connected to the two opposite ends of each conductive conduit 3018 and are also connected to other components 305 of the detection device 300 (including, but not limited to, a sound module), and whether a closed circuit or an open circuit is formed is determined by how the ball 3016 moves.
[0027] 3H, the trigger module 301 comprises a hemispherical structure 3019, in which several transmission lines 30191 and several holes 30192 are fitted, and several conductive balls 30193 are located. Each transmission line 30191 has one or more holes 30192, and each hole 30192 is completely filled with at least one conductive ball 30193. Reasonably, this type is a further variation of the type shown in FIG. 3G, and is used to more accurately and flexibly detect the movement of an object attached to the detection device 300 along many directions intersecting with the hemispherical structure 3019. It should be noted that the operation of the transmission line 30191 having several holes 30192 corresponds to the operation of a combination of several conductive pipes and several insulated conductors arranged to intersect with each other, and the fact that several holes 30192 are completely filled with several conductive balls 30193 can be considered to form a closed circuit by electrically connecting each conductor. In addition, different transmission lines 30191 located in different parts of the hemispherical structure 3019 and extending in different directions are used to detect the distribution of these conductive balls 30193 in different parts along different directions, and are basically used only to detect more of the above-mentioned types of messages that change along one and only one axis. Therefore, by using such a hemispherical structure 3019, the detection signal is determined by multi-dimensional movement affected by gravity and velocity effects, i.e., the detection device 300 can appropriately detect the movement in multiple dimensions of an object attached to it. Here, for simplicity of illustration, only the hemispherical structure 3019 is depicted.
[0028] In the situation shown in Figure 3I, the detection signal is related to the relative movement between two objects (or the relative movement between two parts of one large object). As shown in Figure 3I, two objects 391 and 392 are close to each other, and the two objects 391 and 392 are each attached to a detection device 3009 via a magnet 3931 to detect the adjacent magnetic field. Reasonably, if the strength of the magnet 3931 is fixed, the strength of the magnetic field detected by the detection device 3009 is directly proportional to the distance between the magnet 3931 and the detection device 3009. In other words, by using the detection device 3009 to detect whether the adjacent magnetic field exceeds a critical value, the relative movement (or relative motion) between the objects 391 and 392 is detected and is signaled by the transmission of a broadband sound signal.
[0029] Briefly, by using different types of trigger modules, various properties of the object to which the detection device is attached can be detected, and changes in the broadband sound signal can be transmitted and displayed. The above-described embodiments are merely examples of the present invention and are not intended to limit the present invention. For example, in some not-shown embodiments, the trigger module uses a gas flow meter to detect the flow rate of gas through the attached object and emits a detection signal only when the detected gas flow rate exceeds a critical value. For example, in some not-shown embodiments, the trigger module uses a photometer to measure the intensity of a light beam on the attached object and continuously generates a detection signal that is directly proportional to the measured light intensity. For example, in some not-shown embodiments, the trigger module includes an electrochemical sensor for determining gas concentration, humidity, or volatile organic compounds, and modifies the detection signal by modifying the voltage, electrical resistance, or current, thereby affecting the broadband sound signal.
[0030] Incidentally, to emphasize the reliability of the present invention, an exemplary experiment was performed to verify the difference between the actual temperature and the temperature detected using a trigger module equipped with the thermistor shown in FIG. 3A. In this experiment, such a detection device was used to detect the temperature of an attached object a total of 15 times, and the detection results were converted into a correction curve of the detected temperature and the intensity of the fast Fourier transform signal using a fast Fourier transform. Five of the 15 detected temperatures were then selected and compared with the actual temperature, the fast Fourier transform signal, and the fast Fourier transform temperature obtained when approximating the detected temperature using a linear equation. Table 1 lists the 15 detected temperatures and their fast Fourier transform temperature values. FIG. 4 lists the detected temperatures, their corresponding fast Fourier signals, and the approximated linear equations. Table 2 lists the correlated values and the percentage difference between them. Clearly, the higher the detected temperature, the greater the change in the corresponding fast Fourier signal. Furthermore, the relationship between the detected temperatures and the fast Fourier signals more appropriately approximates the straight line of the linear equation described below. y (temperature) is equal to 11.627FFT-signal (Fast Fourier signal) + 12.563, and the difference between the two squares is R 2 is equal to 0.9712. Furthermore, within the detection range of this experiment, the percentage difference is less than approximately 10 parts per hundred, and approximately 7 parts per hundred, except for the middle part of the detection temperature. Therefore, more experiments will undoubtedly be conducted to at least further optimize the detection device, for example, to optimize the specific thermistor and the specific crystal oscillator used, so as to more accurately measure the temperature of an object and more accurately convert it into a broadband sound signal. It should be emphasized that the present invention is not limited to any specific details of the detection device, for example, to any particular combination of thermistor and crystal oscillator. Therefore, many details have been omitted to avoid unnecessary confusion.

[0032] [Table 2] JPEG0007788728000002.jpg55170
[0033] Incidentally, to emphasize the reliability of the present invention, an exemplary experiment was performed to verify the difference between the actual distance and the predicted distance using a determination system having an analyzer equipped with a sound module emitting ultrasonic waves at a frequency of 32 kHz and a high-resolution analog-to-digital conversion microphone. In this experiment, such a determination system was used to determine different distances between the attached object and the analyzer, and a fast Fourier transform was used to convert the detection results into a correction curve of the predicted distance and the intensity of the fast Fourier signal. Table 3 shows these predicted distances, these fast Fourier signals, the actual distance, and the percentage difference between the predicted distance and the actual distance. Obviously, the larger the predicted distance, the smaller the fast Fourier transform signal. Furthermore, the relationship between these predicted distances and these fast Fourier transform signals is reasonably close to an n-degree equation (n is not equal to 1) and a curve with two variables. y(distance) is 115.55 FFT-Signal -0.919 (Fast Fourier signal) and the difference between the two squares R 2 is equal to 0.9885. Therefore, more experiments will undoubtedly be conducted to further optimize at least the determination system, for example, to optimize the sound module, analyzer, or crystal oscillator used, so as to more accurately detect the distance of the object and more accurately convert it into a broadband sound signal. It should be emphasized that the present invention is not limited to any particular details of the determination system, for example, to any particular combination of sound module, analyzer, and crystal oscillator. Therefore, more details have been omitted to avoid unnecessary confusion.
[0034] [Table 3] JPEG0007788728000003.jpg89170
[0035] Furthermore, the above-described invention is used to detect the position and / or movement of one or more objects, and the detectors attached to these objects do not directly detect the position and / or movement of the objects. That is, for each detector, the transmitted distant broadband sound signal is static and fixed, or the detection signal sent by the trigger module is static and fixed. However, if a specific object and / or an analyzer are not static and fixed in space, the relative geometric relationship between the specific object and the analyzer is dynamic and changing. Therefore, the emitted broadband sound signal of the distant specific object is also dynamic and different from the broadband sound signal received by the analyzer, and this dynamic difference is used to detect the relative distance and / or relative movement speed between the specific object and the detector.
[0036] As is well known, the square of the amplitude of a signal in three-dimensional space is inversely proportional to the distance. Therefore, the analyzer determines the relative distance between the detector and the object to which the analyzer is attached by analyzing the change in intensity of the broadband sound signal transmitted from the detector. The analyzer also determines the relative distance between the detector and a particular detector (or the object to which the particular detector is attached) by comparing the initial amplitude of the broadband sound signal with the actual amplitude when received by the analyzer. Typically, the analyzer preloads the broadband sound signal generated by the particular detector to the initial amplitude when emitted and transmitted from the distant particular detector.
[0037] As is well known, the Doppler effect refers to the difference in frequency between emitted and received waves due to relative motion between the emitter and receiver. Therefore, an analyzer can determine the relative motion between a particular detector (or object to which the particular detector is attached) by analyzing the change in frequency of a broadband sound signal transmitted from the detector. Furthermore, by comparing the initial frequency of the broadband sound signal with the actual frequency as received by the analyzer, the analyzer can determine the relative motion between a particular detector (or object to which the particular detector is attached). Typically, the analyzer preloads the broadband sound signal generated by the particular detector to the initial frequency as emitted and transmitted from the particular detector.
[0038] The detection device and determination system of the present invention can be applied to many application scenarios. For example, smart fitness equipment can use the present invention to monitor every movement of every part of the fitness equipment. Any conventional technology currently used in smart fitness equipment can be applied to any monitoring, except that the broadband sound signal used by the present invention can replace Wi-Fi, Bluetooth, or other wireless communications currently used in smart fitness equipment. For example, in the Internet of Things, the present invention can be used to establish communication with many devices, because the analysis device receives broadband sound signals from many detection devices, all with slightly different frequencies.

It will be apparent to those skilled in the art that various modifications and improvements can be made to the above examples.
