Description

Technical Field

[0001] The present application relates to the technical field of neonatal care, and in particular to a soothing device, a soothing appliance and a soothing method. Background Art

[0002] Clinical research and practice have shown that newborns are often in a state of high anxiety and stress due to their incomplete physiological development. Premature babies in particular have a much greater need for stability and relief than full-term newborns.

[0003] To meet this need, a variety of devices and methods have been developed to soothe premature babies, such as using non-invasive methods such as music, soft light, and touch to reduce premature babies' sense of stress and improve their sleep quality.

[0004] However, these methods are not able to simulate the experience of newborns in the mother's womb very well. Therefore, these methods are not effective enough in soothing newborns. Summary of the invention

[0005] The purpose of the present application is to provide a soothing device, a soothing appliance and a soothing method, which can better soothe a newborn by simulating the vibration and sound felt by the newborn in the mother's body.

[0006] In a first aspect, the present application provides a soothing device, comprising a shell, a controller, a vibration element and an audio output element; a accommodating space is formed inside the shell, and the controller, the vibration element and the audio output element are respectively arranged in the accommodating space; the vibration element and the audio output element are respectively electrically connected to the controller.

[0007] The soothing device described above can better simulate the experience of a newborn in the mother's womb by outputting heartbeat-like vibrations at the frequency of a heartbeat through a vibration element and outputting soothing audio through an audio output element, thereby achieving better soothing of the newborn.

[0008] In combination with the first aspect, optionally, the vibration element includes a linear resonator.

[0009] The soothing device determines the amplitude of the simulated heartbeat vibration signal to be consistent with the heartbeat amplitude of the newborn's mother, and outputs the vibration through the linear resonator. Since the working principle of the linear resonator is mainly based on resonance and has higher precision vibration control, it further simulates a more realistic maternal living environment, thereby further improving the effect of soothing the newborn.

[0010] In combination with the first aspect, optionally, the linear resonator has a linear vibration direction; the shell has a length direction; and the linear vibration direction is oblique to the length direction.

[0011] The soothing device described above has a linear vibration direction obliquely intersecting with the length direction of the shell, so that when the soothing device outputs vibration, the shell has vibration components in the length direction and the width direction orthogonal to the length direction, thereby avoiding the need to find the strongest vibration direction to determine the installation direction of the soothing device when installing the soothing device on the neonatal equipment. That is, the soothing device is more convenient to use.

[0012] In combination with the first aspect, optionally, the shell includes a bottom wall; and the linear vibration direction is oblique to the plane where the bottom wall is located.

[0013] The above-mentioned soothing device, through the oblique intersection of the linear vibration direction with the plane where the bottom wall is located, makes the soothing device also have a vibration component in the height direction which is orthogonal to the length direction and width direction of the shell during the process of outputting vibration, thereby further improving the convenience of use of the soothing device.

[0014] In combination with the first aspect, optionally, the shell includes a first sub-shell and a second sub-shell; the accommodating space includes a first accommodating sub-space formed inside the first sub-shell and a second accommodating sub-space formed inside the second sub-shell; the first sub-shell is connected to the second sub-shell through a connecting member; the controller and the audio output element are respectively arranged in the first accommodating sub-space; and the vibration element is arranged in the second accommodating sub-space.

[0015] The soothing device mentioned above increases the distance between the audio output element and the vibration element by installing the audio output element and the vibration element in the first sub-shell and the second sub-shell respectively, and uses a connector to connect the first sub-shell and the second sub-shell, so that the soothing device can be arranged more flexibly in plush toys and other utensils. For example, the soothing device is placed in a long strip of toys, the vibration shell is smaller and can be closer to the chest or abdomen of the newborn, while the shell containing the battery control board and the speaker is larger and can be arranged at the far end without being close to the newborn. This further improves the effect of soothing the newborn.

[0016] In combination with the first aspect, optionally, the connecting member includes an elastic connecting rod.

[0017] The soothing device, by connecting the first sub-shell and the second sub-shell with an elastic connecting rod, can better maintain the distance between the first sub-shell and the second sub-shell compared to flexible connecting members such as flexible cables, thereby improving the safety of the soothing device.

[0018] In a second aspect, the present application provides a soothing appliance, including a neonatal appliance and the soothing device described in the first aspect.

[0019] The soothing device described above has the same beneficial effects as the supporting member provided in the first aspect and any optional implementation manner of the first aspect, and will not be described in detail here.

[0020] In combination with the second aspect, optionally, the neonatal appliance includes an outer layer; the material of the outer layer includes a flexible material; and filling particles are provided inside the outer layer to wrap the vibration element or the soothing device.

[0021] The soothing device described above has a strong vibration in the longitudinal direction of the linear resonator and is significantly weak in the other two directions. When the linear resonator is installed at a certain angle, the directionality of the vibration on the shell surface is not so strong. The soothing device is placed in a strip pillow and surrounded by filling particles. The filling particles are wrapped in a flexible material, and on the one hand, they have fluidity, so that the soothing device can be deformed and adjusted to its relative position and usage with the newborn at will. On the other hand, they have rigidity, and when the filling particles tightly wrap the soothing device, they have the effect of transmitting vibration. Since the filling particles can be distributed in all directions, the contact between them is also close. The vibration on the shell surface is transmitted to the filling particles in contact with it, and is transmitted to the contacting skin of the newborn through the flexible material through the contact path between the filling particles. Therefore, the path for the vibration of the shell to be transmitted to the skin of the newborn is in all directions and has no directionality. Therefore, the vibration felt by the newborn is more uniform and three-dimensional. This further simulates a more realistic maternal living environment and further improves the effect of soothing the newborn.

[0022] In a third aspect, the present application provides a soothing method, comprising: a soothing device outputs heartbeat-like vibrations and soothing audio according to a pre-stored soothing signal; wherein the pre-storage method of the soothing signal comprises: obtaining a mother's heartbeat signal; filtering the heartbeat signal to obtain a low-frequency signal; and storing a first signal and a second signal in the low-frequency signal in a first channel and a second channel, respectively.

[0023] The above-mentioned soothing method has the same beneficial effects as the supporting member provided in the first aspect and any optional implementation manner of the first aspect, and will not be repeated here.

[0024] In combination with the third aspect, optionally, the first signal includes a vibration signal in the low-frequency signal, and the second signal includes an audio signal in the vibration signal in the low-frequency signal.

[0025] The above-mentioned soothing method realizes stereo output of low-frequency signals by storing low-frequency vibration signals and audio signals in different channels respectively, and outputting them to vibration elements and audio output elements respectively through different channels, thereby further simulating a more realistic maternal living environment, thereby further improving the effect of soothing newborns.

[0026] In summary, the soothing device, soothing appliance, and soothing method provided by the present application, by means of a vibration element that outputs heartbeat-like vibrations at the frequency of a heartbeat and an audio output element that outputs soothing audio, better simulates the experience of a newborn in the mother's body, thereby achieving better soothing of the newborn. By making the linear vibration direction oblique to the length direction of the shell and the plane where the bottom wall is located, the soothing device also has vibration components in the length direction, width direction, and height direction of the shell during the process of outputting vibrations, thereby avoiding the need to find the strongest vibration direction to determine the installation direction of the soothing device during the process of installing the soothing device on the neonatal appliance. In other words, the ease of use of the soothing device is improved. By installing the audio output element and the vibration element in the first sub-shell and the second sub-shell respectively, and connecting the first sub-shell and the second sub-shell with a connector, the distance between the audio output element and the vibration element is increased, so that the soothing device can be arranged more flexibly in plush toys and other utensils. For example, the soothing device is placed in a long strip of toys, the vibration shell is smaller and can be closer to the chest or abdomen of the newborn, while the shell containing the battery control board and the speaker is larger and can be arranged at the far end without being close to the newborn. This further improves the effect of soothing the newborn. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0041] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the invented product is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0042] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0043] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] Most of the current soothing devices have vibration devices that provide a certain frequency and intensity of rotational oscillation to soothe newborns. Or they can generate a certain regular pulse signal to the rotating motor, driving the eccentric rotor to produce a heartbeat effect, so as to soothe the nervous and uneasy emotions of humans or animals.

[0045] However, the current soothing devices of this type have unsatisfactory soothing effects due to fixed vibration patterns or simple sound playback, single vibration intensity and frequency, and may even have adverse effects on premature infants in some cases.

[0046] Research has found that the sounds that the fetus hears most often in the womb are the mother's own sounds, including heartbeats (which are the first and most persistent sounds that the fetus hears, about 160-180 times / minute), blood flow, gastrointestinal motility, and other sounds produced by internal physiological activities. These sounds form a continuous and stable background sound environment that soothes the fetus. Due to physical characteristics, the high-frequency parts of these sounds are attenuated more by media such as the uterus, amniotic fluid, and adipose tissue during the transmission process; while the low-frequency parts are more likely to penetrate these barriers and reach the fetus' ears.

[0047] The sounds that a fetus hears most often in the womb leave an imprint in the fetus' brain. After birth, the newborn may show a preference for or faster recognition of these familiar sounds.

[0048] Neonatal heartbeat sound soothing is a method that uses heartbeat sounds similar to those heard in the mother's womb to help newborns feel safe and relaxed. Compared with complex and changing external sounds, simple and repetitive heartbeat sounds are less likely to overstimulate the newborn's senses, helping to maintain their sensory balance and avoid over-arousal. Heartbeat sound soothing is a natural, gentle and effective soothing method that uses the newborn's innate physiological memory to help them feel comfortable and peaceful during the transition period after birth, and has a positive effect on promoting the psychological and physical health of newborns.

[0049] Heartbeat vibration soothing can provide a rhythmic vibration similar to that felt in the mother's womb to the newborn directly through physical contact or a vibration device that simulates the heartbeat, which helps calm and soothe the newborn. The vibration sensation can be transmitted through skin touch and may have a more direct effect on the newborn's muscle relaxation and emotional stability.

[0050] In view of this, the present application provides a soothing device, a soothing appliance and a soothing method in combination with the above research results to solve the problems existing in most current soothing devices. Specifically, please refer to the embodiments and drawings provided in the present application.

[0051] Please refer to Figure 1 and Figure 2 , Figure 1 This is a first stereoscopic diagram of the soothing device 100 provided in an embodiment of the present application; Figure 2 : is an exploded view of the soothing device 100 provided in an embodiment of the present application. The soothing device 100 provided in an embodiment of the present application can be used to be installed on a neonatal appliance 200 to soothe a newborn. The soothing device 100 may include a housing 110, a controller 120, a vibration element 130, and an audio output element 140. A accommodating space may be formed inside the housing 110, and the controller 120, the vibration element 130, and the audio output element 140 may be respectively arranged in the accommodating space. The vibration element 130 and the audio output element 140 may be electrically connected to the controller 120, respectively. The vibration element 130 may be configured to output a heartbeat-like vibration in response to a heartbeat-like vibration signal of the controller 120. The audio output element 140 may be configured to output a soothing audio in response to a soothing audio signal of the controller 120.

[0052] The newborn appliance 200 may be a toy, a pillow or a newborn bed. The vibration element and / or the audio may be placed on the surface or inside the bed, and the controller, the power switch, etc. are all inside the bed. The connection relationship is a rigid connection. It is preferably removable. In this way, the vibration and audio signals can be better transmitted without being restricted by the original soothing device housing 110. The controller 120 may be a circuit board integrated with components such as a touch switch, a USB interface, a connector, an audio playback chip, an audio storage chip, and an audio power amplifier chip.

[0053] The vibration element 130 may be a pneumatic vibrator, an electromagnetic vibrator, a linear resonator, etc. The audio output element 140 may be a speaker.

[0054] The controller 120 may pre-store a heartbeat signal obtained from the mother, and may filter the heartbeat signal to obtain a low-frequency signal. Finally, the heartbeat-like vibration signal and the soothing audio signal in the low-frequency signal may be stored in different channels respectively. In the process of the soothing device 100 soothing the newborn, the controller 120 may output the heartbeat-like vibration signal to the vibration element 130 so that the vibration element 130 vibrates at the frequency of the heartbeat; the controller 120 may also output the soothing audio to the audio output element 140 so that the audio output element 140 plays the soothing audio. Among them, the soothing audio may imitate the heartbeat sound heard by the newborn in the mother's body, or it may be soothing music, such as a lullaby, etc., or it may be breathing sounds, bowel sounds, etc.

[0055] In the above implementation process, the vibration element 130 outputs the simulated heartbeat vibration at the heartbeat frequency and the audio output element 140 outputs the soothing audio, which better simulates the experience of the newborn in the mother's body, thereby achieving better soothing of the newborn.

[0056] In some optional embodiments, the vibration element 130 may include a linear resonator. The amplitude of the heartbeat-simulating vibration signal may be consistent with the heartbeat amplitude of the newborn's mother.

[0057] The linear resonator usually has obvious vibration in one direction. The amplitude of the simulated heartbeat vibration signal can be determined by obtaining the amplitude of the heartbeat signal from a pre-stored heartbeat signal.

[0058] In the above implementation process, the amplitude of the simulated heartbeat vibration signal is determined to be consistent with the heartbeat amplitude of the newborn's mother, and the linear resonator outputs the vibration. Since the working principle of the linear resonator is mainly based on resonance and has higher precision vibration control, a more realistic maternal living environment is further simulated, thereby further improving the effect of soothing the newborn.

[0059] Please refer to Figure 3 , Figure 3 1 is a partial exploded view of the soothing device 100 provided in an embodiment of the present application. In some optional embodiments, the linear resonator may have a linear vibration direction. The housing 110 may have a length direction. The linear vibration direction may be oblique to the length direction.

[0060] The angle between the linear vibration direction and the length direction of the shell 110 can be 10°, 15°, 30°, 45°, 50°, 60°, 65°, 70°, 75°, etc.

[0061] In the above implementation process, the linear vibration direction is obliquely intersected with the length direction of the housing 110, so that when the soothing device 100 outputs vibration, the housing 110 has vibration components in both the length direction and the width direction orthogonal to the length direction, thereby avoiding the need to find the strongest vibration direction to determine the installation direction of the soothing device 100 when installing the soothing device 100 on the neonatal appliance 200. That is, the soothing device 100 is more convenient to use.

[0062] Please continue to refer to Figure 3 In some optional embodiments, the housing 110 may include a bottom wall 1111. The linear vibration direction may be oblique to the plane where the bottom wall 1111 is located.

[0063] The angle between the length direction of the shell 110 and the plane where the bottom wall 1111 is located can be 20°, 30°, etc.

[0064] During the above implementation process, the linear vibration direction is obliquely intersected with the plane where the bottom wall 1111 is located, so that when the soothing device 100 outputs vibration, the height direction that is orthogonal to the length direction and the width direction of the shell 110 also has a vibration component, thereby further improving the ease of use of the soothing device 100.

[0065] Please refer to Figure 4 , Figure 4 1 is a second stereoscopic diagram of the soothing device 100 provided in an embodiment of the present application. In some optional embodiments, the housing 110 may include a first sub-housing 111 and a second sub-housing 112. The accommodation space may include a first accommodation sub-space formed inside the first sub-housing 111 and a second accommodation sub-space formed inside the second sub-housing 112. The first sub-housing 111 may be connected to the second sub-housing 112 via a connector 113. The controller 120 and the audio output element 140 may be respectively disposed in the first accommodation sub-space. The vibration element 130 may be disposed in the second accommodation sub-space.

[0066] That is, the audio output element 140 and the vibration element 130 are respectively disposed in different housings 110. The connector 113 may be a flexible cable or a flexible hollow silicone column, etc. A wire may be disposed inside the flexible cable or the flexible hollow silicone column, etc.

[0067] In the above implementation process, by installing the audio output element 140 and the vibration element 130 in the first sub-shell 111 and the second sub-shell 112 respectively, and connecting the first sub-shell 111 and the second sub-shell 112 with the connector 113, the distance between the audio output element 140 and the vibration element 130 is increased, so that the soothing device 100 can be arranged more flexibly in a plush toy or other utensils. For example, when the soothing device 100 is placed in a long strip of toy, the vibration shell is smaller and can be closer to the chest or abdomen of the newborn, while the shell containing the battery control board and the speaker is larger and can be arranged at the far end without being close to the newborn. This further improves the effect of soothing the newborn.

[0068] In some optional embodiments, the connecting member 113 may include an elastic connecting rod.

[0069] The flexible hollow silicone column can be used as an elastic connecting rod.

[0070] In the above implementation process, by using an elastic connecting rod to connect the first sub-shell 111 and the second sub-shell 112, compared with flexible connectors 113 such as flexible cables, the distance between the first sub-shell 111 and the second sub-shell 112 can be better maintained, thereby improving the safety of the soothing device 100.

[0071] Please refer to Figures 5 to 7 , Figure 5 This is a first stereoscopic view of the soothing device 10 provided in the embodiment of the present application; Figure 6 is a second stereoscopic view of the soothing appliance 10 provided in the embodiment of the present application; Figure 7 This is a third stereoscopic view of the soothing appliance 10 provided in the embodiment of the present application. Based on the same concept, the soothing appliance 10 provided in the embodiment of the present application may include a newborn appliance 200 and the soothing device 100 described above.

[0072] Likewise, the newborn supplies 200 may be a toy, a pillow, or a newborn bed.

[0073] The above implementation process may be the same as the soothing device 100 described above, and will not be repeated here.

[0074] Please refer to Figure 8 , Figure 8 Schematic diagram of filling particles of the soothing device 10 provided in the embodiment of the present application. In some optional embodiments, the neonatal device 200 may include an outer layer 210. The material of the outer layer 210 may include a flexible material. Filling particles 300 may be provided inside the outer layer 210 to wrap the vibration element 130 or the soothing device 100.

[0075] The flexible material can be various fabrics such as cotton cloth, etc. The filling particles 300 can be EPS (Expanded Polystyrene, expanded polystyrene) or EPP (Expanded Polypropylene, expanded polypropylene), EPE (Expanded polyethylene foamed polyethylene) and the like.

[0076] In the above implementation process, since the vibration of the linear resonator is stronger in the length direction, it is obviously weaker in the other two directions. When the linear resonator is installed at a certain angle, the directionality of the vibration on the shell surface is not so strong. The soothing device 100 is placed in the bar pillow, and the soothing device 100 is surrounded by filling particles 300. Since the filling particles 300 are irregularly distributed, the contact between each other is also irregular. The vibration on the shell surface is transmitted to the filling particles 300 in contact with it, and is transmitted to the contacting skin of the newborn through the contact path between the filling particles 300 through the flexible material. Therefore, the path for the vibration of the shell to be transmitted to the skin of the newborn is irregular and non-directional. Therefore, the vibration felt by the newborn is more uniform. This further simulates a more realistic maternal living environment and further improves the effect of soothing the newborn.

[0077] Based on the same concept, the soothing method provided in the embodiment of the present application may include:

[0078] Step S110: the soothing device 100 outputs heartbeat-simulating vibration and soothing audio according to the pre-stored soothing signal.

[0079] In the above step S110, the heartbeat-like vibration and the soothing audio can be output to the vibration element 130 and the audio output element 140 through different channels. For example, the heartbeat-like vibration can be output to the vibration element 130 through the left channel, and the soothing audio can be output to the audio output element 140 through the right channel.

[0080] Please refer to Fig. 9 , Fig. 9 1 is a method flow chart of a method for pre-storing a soothing signal in a soothing method provided in an embodiment of the present application. The pre-storage method of the soothing signal may include:

[0081] Step S001: Obtain the mother's heartbeat signal.

[0082] In the above step S001, the mother's heartbeat can be recorded by a microphone or a vibration sensor, such as a piezoelectric ceramic sensor. Specifically, the microphone or vibration sensor can be attached to the surface of the mother's skin in the auscultation area to collect the heartbeat signal, and the collected signal can be converted into a digital audio format, such as WAV, MP3 format, etc.

[0083] Step S002: Filter the heartbeat signal to obtain a low-frequency signal.

[0084] In the above step S002, the heartbeat signal is filtered to retain only the low-frequency signal. Generally, the penetration ability of the low-frequency signal is stronger than that of the medium- and high-frequency signals.

[0085] Step S003: storing the first signal and the second signal in the low-frequency signal in the first channel and the second channel respectively.

[0086] In the above step S003, the first signal may be a simulated heartbeat vibration signal, and the first channel may be a left channel. The second signal may be a soothing audio signal, and the first channel may be a right channel.

[0087] The above implementation process may be the same as the soothing device 100 described above, and will not be repeated here.

[0088] In some optional implementations, the first signal may include a vibration signal in the low-frequency signal, and the second signal may include an audio signal in the vibration signal in the low-frequency signal.

[0089] The vibration signal may be a heartbeat-like vibration signal. The audio signal may be a soothing audio signal, specifically, it may be a sound that imitates the heartbeat heard by a newborn in the mother's womb, or it may be soothing music, such as a lullaby.

[0090] In the above implementation process, by storing the low-frequency vibration signal and the audio signal in different channels respectively, and outputting them to the vibration element 130 and the audio output element 140 respectively through different channels, a stereo output of the low-frequency signal is achieved, thereby further simulating a more realistic maternal living environment, thereby further improving the effect of soothing the newborn.

[0091] In summary, the soothing device 100, soothing appliance 10 and soothing method provided in each embodiment of the present application, by means of the vibration element 130 outputting heartbeat-like vibration at the frequency of the heartbeat and the audio output element 140 outputting soothing audio, better simulates the experience of the newborn in the mother's body, thereby achieving better soothing of the newborn. By making the linear vibration direction oblique to the length direction of the shell 110 and the plane where the bottom wall 1111 is located, the soothing device 100, in the process of outputting vibration, also has vibration components in the length direction, width direction and height direction of the shell 110, respectively, avoiding the problem of needing to find the strongest vibration direction to determine the installation direction of the soothing device 100 in the process of installing the soothing device 100 on the neonatal appliance 200. That is, the ease of use of the soothing device 100 is improved. By installing the audio output element 140 and the vibration element 130 in the first sub-shell 111 and the second sub-shell 112 respectively, and connecting the first sub-shell 111 and the second sub-shell 112 with the connector 113, the distance between the audio output element 140 and the vibration element 130 is increased, so that the soothing device 100 can be arranged more flexibly in plush toys and other utensils. For example, when the soothing device 100 is placed in a long toy, the vibration shell is smaller and can be closer to the chest or abdomen of the newborn, while the shell containing the battery control board and the speaker is larger and can be arranged at the far end without being close to the newborn. This further improves the effect of soothing the newborn.

[0092] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
