Description

Skin treatment device and its operating method

[0001] The present invention relates to a skin treatment device and its operating method. In particular, it relates to a technical concept that can enhance the effectiveness of treatment by applying electrical energy to the skin.

[0002]

[0003] There is a known method of treating skin diseases and fat using electrical energy such as RF pulse energy or high-frequency energy.

[0004] For example, there is the unipolar method, which uses the body as a (-) ground and the (+) handpiece to contact the skin and use it in a vertical downward manner, and the bipolar method, which applies electrical energy from both sides by sucking the skin.

[0005] An example of this bipolar method is also disclosed in Korean Patent No. 10-2407711, "Therapeutic Handpiece with Vacuum Cap," filed and registered by the applicant of the present invention. The contents of the previous patent may be incorporated by reference into the present invention.

[0006] As disclosed in the previous patent, by sucking the skin to form the skin in three dimensions and then applying electrical energy through the placed electrodes, the fat component melts and a therapeutic effect can be achieved.

[0007] However, this conventional method has a problem in that the skin may not adhere well to the electrode.

[0008] Figure 1 is a drawing for explaining the problems of conventional skin treatment devices.

[0009] As shown in Fig. 1, a conventional skin treatment device (10) forms negative pressure through a hole (12) to suck skin into a cavity provided in the skin treatment device (10) and then irradiates electrical energy through an electrode pair (11) to perform skin treatment.

[0010] However, as shown in Fig. 1, when the skin is suctioned, the suctioned skin is formed like a mountain peak, so the degree of adhesion to the electrodes arranged on both ends is considerably low. Normally, when suction is performed by simply applying negative pressure through a vacuum device, only about 30 to 40% of the suctioned skin area is in contact with the electrode, and the remaining 60 to 70% is not in contact. Since electrical energy is irradiated only to the contacted skin area, there is a problem that the effect of skin treatment is reduced. In other words, even if the suction pressure on the skin is increased, there is a limit to the degree of skin adhesion to the electrode.

[0015]

[0016] The problem to be solved by the present invention is to provide a technical idea that can dramatically increase the area of ​​contact with the electrode while the skin is sucked into the cavity, thereby enhancing the therapeutic effect through electric energy.

[0017] It also provides a technical idea that by applying pressure to the skin to provide a massage effect, the tissue of the skin fat is destroyed or softened so that it can be better decomposed by electrical energy.

[0018]

[0019] In order to solve the above technical problem, a skin treatment device according to an embodiment of the present invention comprises a skin receiving cap having an open lower surface and a cavity therein, an electrode pair arranged to face each other in a first direction so that the sucked skin is contacted within the cavity of the skin receiving cap when a target area of ​​the skin is sucked toward the cavity of the skin receiving cap, a driving device for driving the pressing plate to enter and retract inwardly from the cavity, a controller for controlling the driving device, and at least one pressing plate driven by the driving device to enter inwardly from the cavity in a second direction different from the first direction, and to push the skin sucked into the cavity inwardly so as to increase the area in contact with the electrode pair.

[0020] The above skin treatment device may have a pair of compression plates arranged to face each other in the second direction.

[0021] The above controller can control the electrode pair to differentially perform irradiation of RF pulses or irradiation intensity according to the operation of the pressing plate.

[0022] At least one of the above pressing plates or at least one of the above electrode pairs may be formed to be inclined at a predetermined angle so that the lower part of the inner surface facing inward of the cavity protrudes further inward than the upper part.

[0023] The above driving device unit can further drive the electrode pair to advance and retreat inwardly from the cavity.

[0024] The above skin treatment device may further include a cooling module capable of cooling the electrode pair.

[0025] The above skin treatment device may further include a vacuum pump that provides negative pressure so that the target area of ​​the skin can be sucked toward the cavity of the skin receiving cap.

[0026] The above driving device unit can repeatedly advance and retract at least one of the pressing plate or the electrode pair at a predetermined frequency.

[0027] The above skin treatment device further comprises a temperature sensor for sensing the temperature of skin sucked into the common portion, and the controller can control the driving device or control whether to operate the skin treatment device based on the sensed temperature.

[0028] According to another aspect, a skin treatment device includes a skin receiving cap having an open bottom and a cavity inside, an electrode pair arranged to face each other in a first direction so that sucked skin is contacted within the cavity of the skin receiving cap when a target area of ​​the skin is sucked toward the cavity of the skin receiving cap, a driving device for driving the electrode pair to advance and retreat inwardly from the cavity, and a controller for controlling the driving device, wherein the electrode pair is driven by the driving device to push the skin sucked into the cavity inwardly so as to increase an area in contact with the electrode pair.

[0029] A method for driving a skin treatment device according to the technical idea of ​​the present invention includes a step in which the skin treatment device sucks a target area of ​​the skin toward a cavity of a skin receiving cap, a step in which the skin treatment device allows a compression plate to enter the cavity in a second direction different from the first direction of an electrode pair arranged in a first direction so that the sucked skin comes into contact within the cavity of the skin receiving cap, and a step in which the skin treatment device irradiates electric energy through the electrode pair.

[0030] The method for driving the skin treatment device may further include a step of the skin treatment device repeatedly entering and retracting at least one of the compression plate or the electrode pair at a predetermined frequency.

[0031] A method for operating a skin treatment device according to another aspect may include a step in which the skin treatment device sucks a target area of ​​the skin toward a cavity of a skin receiving cap, a step in which the skin treatment device introduces an electrode pair arranged in a first direction into the cavity of the skin receiving cap so that the sucked skin comes into contact with the cavity, and a step in which the skin treatment device irradiates electric energy through the electrode pair.

[0032]

[0033]

[0034] According to an embodiment of the present invention, by pushing the skin toward the center of the cavity with a compression plate and / or electrode while the skin is sucked into the cavity, the area in contact with the electrode can be dramatically increased, thereby increasing the area of ​​the skin to which electric energy is applied, thereby increasing the therapeutic effect.

[0035] It also has the effect of applying pressure to the skin to provide a massage effect, thereby destroying or softening the tissue of the skin fat, making it more receptive to electrical energy.

[0044]

[0045] The present invention is susceptible to various modifications and embodiments, and specific embodiments are illustrated and described in detail in the drawings. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention. In describing the present invention, detailed descriptions of related known technologies will be omitted if they are deemed to obscure the gist of the present invention.

[0046] Terms such as first, second, etc. may be used to describe various components, but these components should not be limited by these terms. These terms are used solely to distinguish one component from another.

[0047] The terminology used in this application is solely for the purpose of describing specific embodiments and is not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly dictates otherwise.

[0048] In this specification, terms such as “include” or “have” are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0049] Hereinafter, the present invention will be described in detail, focusing on embodiments thereof, with reference to the attached drawings. The same reference numerals in each drawing represent the same components.

[0050] FIG. 2 is a drawing showing a schematic configuration of a skin treatment device according to an embodiment of the present invention.

[0051] Referring to FIG. 2, a skin treatment device (1000) according to the technical concept of the present invention may include a skin receiving cap (100). The skin receiving cap (100) has a space, i.e., a cavity, through which skin can be sucked, as disclosed in a previous patent (a vacuum cap in the previous patent).

[0052] In one embodiment, the cavity may have a rectangular prism shape with a rectangular cross-section, but is not necessarily limited thereto. The cavity has an open lower surface through which skin can be sucked.

[0053] The above skin receiving cap (100) may be provided with an electrode pair (110) arranged to face each other in a first direction (e.g., in the depth direction of the drawing) so that when a target area of ​​the skin is absorbed toward the cavity of the skin receiving cap (100), the absorbed skin can be brought into contact within the cavity of the skin receiving cap (100). Electrical energy can be applied to the skin in contact with the electrode pair (110) through the electrode pair (110). It goes without saying that the electrode pair (1101) can be implemented to irradiate electrical energy in various ways and embodiments, such as RF pulses and high-frequency currents.

[0054] In addition, the skin receiving cap (100) may be provided with at least one compression plate (120, 121) that can enter and then retreat toward the center of the cavity according to the technical idea of ​​the present invention. The compression plates (120, 121) may be arranged to face each other in a second direction (e.g., the left-right direction in the drawing) that is different from a first direction (e.g., the depth direction in the drawing). When the compression plates (120, 121) enter the center through the driving device unit (130, 131), the skin sucked into the cavity is pushed toward the center, and in this case, the volume of the cavity is reduced, so that the area of ​​the skin in contact with the electrode pair (110) can become very large.

[0055] Ultimately, the technical idea of ​​the present invention is to increase the area of ​​the target area of ​​the sucked skin that comes into contact with the electrode pair (110) by mechanically pushing the skin toward the center through the compression plate (120, 121) after sucking the skin into the common area. Accordingly, the area of ​​the skin to which the electrical energy irradiated through the electrode pair (110) is applied can be increased, thereby enhancing the fat decomposition effect.

[0056] The above skin receiving cap (100) can be combined with the body part (500) to implement the technical idea of ​​the present invention.

[0057] As disclosed in the previous patent, the body part (500) can be rotatably coupled to the skin receiving cap (100), thereby enabling the therapist to easily adjust the angle to a desired angle during skin treatment while holding the body part (500).

[0058] In order to implement the technical idea of ​​the present invention, the skin needs to be sucked into the cavity, and various methods may be possible for this.

[0059] According to one embodiment, the skin treatment device (1000) can suction skin by applying negative pressure to the cavity through a vacuum pump (or vacuum device, 200). The vacuum pump (200) is connected to a vacuum valve (210) through a predetermined pipe, and the vacuum valve (210) can be connected to a hole (220) that communicates with the skin receiving cap (100). Through this, a predetermined negative pressure can be applied to the skin receiving cap (100). The skin receiving cap (100) or the vacuum valve (210) can be equipped with a predetermined vacuum pressure sensor (not shown), through which the negative pressure applied to the cavity can be sensed.

[0060] The negative pressure applied to the cavity can be controlled by the controller (400). The controller (400) can control the negative pressure applied to the cavity by controlling the vacuum pump (200) and / or the vacuum valve (210). According to one embodiment, the controller (400) can provide a physical stimulus in which the skin is sucked into the cavity and rises upward and then falls while changing the size of the negative pressure applied to the cavity at a certain cycle, thereby providing not only a massage effect but also an effect of destroying or gently massaging the fatty tissue inside the skin.

[0061] While one embodiment of the present invention exemplifies a case where skin is sucked into the cavity by applying negative pressure via a vacuum pump (200), the present invention is not necessarily limited to this. For example, the skin may be grasped by hand, the target area of ​​the skin may be protruded upward, and then the skin may be manually inserted into the cavity.

[0062] Meanwhile, the skin receiving cap (100) of the above skin treatment device (1000) may be equipped with a driving device (130, 131).

[0063] The above driving device (130, 131) can drive at least one compression plate (120, 121) according to the technical idea of ​​the present invention. In Fig. 2, an example is shown in which the compression plates (120, 121) are provided to face each other toward the center of the common portion, but the present invention is not necessarily limited thereto. For example, only one of the compression plates (120, 121) may be provided and the other may be fixedly arranged. Even in this case, an average expert in the technical field of the present invention will be able to easily infer that the area of ​​the skin contacting the electrode pair (110) may be larger compared to the conventional case in which the compression plates (120, 121) are not provided.

[0064] Meanwhile, in this specification, a case is representatively described in which the compression plate (120, 121) enters and then retreats toward the center of the cavity by the driving device (130, 131), but depending on the embodiment, the skin treatment device (1000) may be implemented so that the electrode pair (110) can also enter and then retreat toward the center of the cavity.

[0065] That is, instead of being equipped with a separate compression plate (120, 121) in the skin receiving cap (100), the electrode pair (110) may be implemented so that it can enter and then retreat toward the center of the common portion, and in this case, the electrode pair (110) may be implemented so that it is connected to a predetermined driving device.

[0066] According to another embodiment, a predetermined driving device (e.g., a cylinder) may be connected to both the electrode pair (110) and the pressing plate (120, 121), in which case both the electrode pair (110) and the pressing plate (120, 121) may be able to enter and retract into the center of the cavity.

[0067] Various embodiments are possible, and in this specification, a case in which the pressing plates (120, 121) are arranged in pairs facing each other to enable entry and retraction into the center of the common portion is representatively described, but the scope of the present invention is not limited thereto.

[0068] The above driving unit (130, 131) may be implemented as a cylinder that can advance or retreat the pressing plate (120, 121). Although FIG. 2 shows an embodiment in which the driving unit (130, 131) is implemented as an air cylinder, an average expert in the technical field of the present invention will be able to easily infer that the driving unit (130, 131) may be implemented in various ways, such as an oil cylinder or a solenoid, depending on the embodiment.

[0069] When the above driving unit (130, 131) is implemented as an air cylinder, the driving unit (130, 131) can be moved forward or backward through the pressure of the gas provided by the compressor (300). The compressor (300) can adjust the pressure by compressing or expanding a predetermined gas, and the compressor (300) can be connected to the driving unit (130, 131) through at least one valve (e.g., solenoid valve, 310, 320). In addition, a pressure sensor (330) can be provided at a predetermined position for sensing the pressure applied to at least one valve (310, 320) or the driving unit (130, 131), through which the driving unit (130, 131) can be controlled.

[0070] The above compressor (300) and / or the at least one valve (310, 320) can be controlled by a controller (400).

[0071] The controller (400) can control the drive unit (130, 131) by controlling the compressor (300) and / or the at least one valve (310, 320). In one example, the controller (400) can control the drive unit (130, 131) to repeatedly advance and retreat the compression plate (120, 121) at a predetermined frequency. In this case, in addition to increasing the skin area in contact with the electrode pair (110) through the compression plate (120, 121), the physical stimulation of the compression plate (120, 121) provides a massage effect in which adipose tissue of the skin is destroyed or softened, thereby further enhancing the effect of lipolysis.

[0072] Of course, as mentioned above, the electrode pair (110) can also be implemented to be able to advance and retreat by the driving device, and in this case, the controller (400) can control the driving device to repeatedly advance and retreat the electrode pair (110) at a predetermined frequency. In this case as well, a massage effect through physical stimulation is of course generated.

[0073] The above controller (400) can control the electrode pair (110) according to the operation of the pressing plate (120, 121) to differentially perform irradiation of electric energy or irradiation intensity.

[0074] Controlling whether or not to irradiate electric energy or the intensity of irradiation according to the operation of the compression plate (120, 121) may mean that whether or not to irradiate electric energy can be controlled depending on the position of the compression plate (120, 121), such as irradiating electric energy only when the compression plate (120, 121) has entered the cavity by a certain degree or more. In addition, the controller (400) may also adjust the intensity of the electric energy to be irradiated depending on the degree to which the compression plate (120, 121) has entered the cavity. For example, the intensity of the electric energy irradiated when the compression plate (120, 121) has entered to the maximum and when it has entered by about 50% may be different. Of course, regardless of the degree of entry, electric energy of the same intensity may be irradiated when the compression plate (120, 121) has entered by a certain degree or more.

[0075] According to one embodiment, the controller (400) can repeatedly advance and retreat the pressing plate (120, 121) at a constant frequency, and at this time, the controller (400) can also irradiate electric energy in accordance with the driving cycle of the pressing plate (120, 121) by irradiating electric energy when entering and not irradiating electric energy when retracting.

[0076] According to another embodiment, the controller (400) may not immediately apply electric energy upon entry of the compression plate (120, 121), but may apply electric energy after a certain period of time. For example, the controller (400) may repeatedly cause the compression plate (120, 121) to enter and retract at a certain frequency, and after the compression plate (120, 121) is fixed in the entered state after such repeated entry and retraction, the controller (400) may apply electric energy through the electrode pair (110) for a certain period of time.

[0077] A person skilled in the art of the present invention will be able to easily infer that the controller (400) can control the driving of the pressing plate (120, 121) and the irradiation of electric energy through the electrode pair (110) in various ways.

[0078] The controller (400) for this purpose may include a predetermined processor, a storage device, and / or a program stored in the storage device and executed by the processor.

[0079] The above controller (400) may perform a function of controlling operations and other components (e.g., driving unit (130, 131), vacuum pump (200), compressor (300), various valves, etc.) for implementing the technical idea of ​​the present invention, and may include a processor, a storage device, and a program stored in the storage device and executed by the processor. In the present specification, it will be easily inferred by an average expert in the technical field to which the present invention pertains that the controller (400) performs a predetermined operation can be performed by a series of data processing and / or control performed by the processor executing the program.

[0080] Meanwhile, a predetermined temperature sensor (600) may be provided at a predetermined location of the skin receiving cap (100), through which an increase in skin temperature due to physical stimulation and / or electrical energy irradiation may be sensed. Furthermore, when the temperature sensor (600) senses that the skin temperature has risen to a predetermined reference temperature, the skin treatment device (1000) may terminate operation.

[0081] FIG. 3 is a drawing for explaining a skin receiving cap of a skin treatment device according to an embodiment of the present invention.

[0082] First, Fig. 3a shows a cross-section in the AA direction of the plan view of the skin receiving cap (100) shown in Fig. 3c, and Fig. 3b shows a cross-section in the BB direction of the plan view.

[0083] As disclosed in FIGS. 3a to 3c, electrode pairs (110, 111) are arranged in a first direction (e.g., in the up-down direction on a plan view) to face each other inside the cavity of the skin receiving cap (100), and skin sucked into the cavity can come into contact with the electrode pairs (110, 111).

[0084] In addition, the electrode pairs (110, 111) and the pressing plates (120, 121) can be arranged to face each other in different directions (e.g., left and right directions on a plan view). In addition, these pressing plates (120, 121) can be moved into and out of the cavity by the driving device (130, 131).

[0085] Meanwhile, as illustrated in FIGS. 3A and 3E, the compression plates (120, 121) may be formed to be inclined at a predetermined angle so that the lower portion of the inner surface facing inward of the cavity protrudes further inward than the upper portion. When negative pressure is applied to the cavity through the hole (220), the target area of ​​the skin that is suctioned is suctioned in the shape of a mountain peak with a wider width at the bottom and a narrower width toward the top. In the case where the inner surface of the compression plates (120, 121) has such an inclined shape with a more protruding lower portion, it can be easier to push upward the skin area within the cavity than in the case where it is not, and through this, there is an effect of rapidly increasing the area in contact with the electrode pair (110, 111).

[0086] Of course, depending on the embodiment, the inner surface of the electrode pair (110, 111) may also be implemented to have a slanted shape with the lower portion protruding more.

[0087] Meanwhile, as illustrated in FIG. 3d, a cooling module (500) may be attached to the outside of the electrode pair (110, 111) to cool the heating of the electrode pair (110, 111). The cooling module (500) may be implemented as a thermoelectric module using a thermoelectric element, for example, but is not limited thereto, and any configuration capable of cooling the electrode pair (110, 111) is sufficient. Through such a cooling module (500), overheating of the electrode pair (110, 111) can be prevented, and there is an effect of extending the treatment time of the skin.

[0088] Additionally, as illustrated in FIG. 3e, a predetermined temperature sensor (600) may be attached to the inner surface of the compression plate (120, 121). In this case, it may be implemented to sense skin temperature by making direct contact with the skin. Of course, as illustrated in FIG. 2, the temperature sensor (600) may be provided at a predetermined position on the upper portion of the skin receiving cap (100), and in this case, it may be implemented as an infrared temperature sensor capable of sensing temperature in a non-contact manner.

[0089] Then, the controller (400) can control the driving device (130, 131) or control whether to operate the skin treatment device (1000) based on the temperature sensed by the temperature sensor (600).

[0090] FIG. 4 is a drawing for explaining the interior of a skin receiving cap when a compression plate enters according to an embodiment of the present invention.

[0091] First, Fig. 4a shows a cross-section in the AA direction of the plan view of the skin receiving cap (100) shown in Fig. 4c, and Fig. 4b shows a cross-section in the BB direction of the plan view.

[0092] As shown in FIGS. 4a to 4c, when the compression plates (120, 121) each enter a certain distance into the cavity, the skin sucked into the cavity is pushed toward the center from both sides, and in this case, as shown in FIG. 4b, it can be seen that the sucked skin comes into contact with the electrode pair (110, 111) over a relatively wide area.

[0093] FIGS. 5 to 7 are drawings for explaining the effects according to the driving method of the skin treatment device according to an embodiment of the present invention.

[0094] FIGS. 5a and 5b are drawings showing the shape change of the skin in the skin receiving cap (100) from different directions before the compression plate (120, 121) enters, respectively, FIGS. 6a and 6b are drawings showing the shape change of the skin in the skin receiving cap (100) from different directions when the compression plate (120, 121) enters only a portion (e.g., 50% of the maximum), and FIGS. 7a and 7b are drawings showing the shape change of the skin in the skin receiving cap (100) from different directions after the compression plate (120, 121) enters to the maximum.

[0095] First, as shown in FIGS. 5a and 5b, before the compression plate (120, 121) enters, the area where the skin sucked into the cavity comes into contact with the electrode pair (110, 111) is relatively small, and accordingly, when electric energy is irradiated, the skin area where the electric energy is irradiated (the area indicated by the red wave in FIG. 5b) also becomes relatively small.

[0096] Afterwards, as shown in FIGS. 6a and 6b, when the compression plate (120, 121) enters only a part (e.g., 50% of the maximum), the area where the skin sucked into the cavity comes into contact with the electrode pair (110, 111) becomes relatively larger than that shown in FIG. 5, and accordingly, when electric energy is irradiated, the skin area where the electric energy is irradiated (the area indicated by the red wave in FIG. 6b) also becomes relatively larger.

[0097] After that, when the compression plates (120, 121) enter the maximum as shown in FIGS. 7a and 7b, the area where the skin sucked into the cavity comes into contact with the electrode pair (110, 111) can reach the maximum, and thus, it becomes relatively larger than that shown in FIG. 5, and accordingly, when electric energy is irradiated, the skin area where the electric energy is irradiated (the area indicated by the red wave in FIG. 7b) can also be irradiated to almost the entire sucked skin area. In addition, when the compression plates (120, 121) enter the maximum in this way, the fat molecules inside the skin are destroyed or softened due to the physical pressure applied to the skin, so that the efficiency of fat decomposition through electric energy can be increased, and when the entry and exit of the compression plates (120, 121) are repeatedly performed at a certain frequency, this effect can be further increased.

[0098] The cases illustrated in FIGS. 5 to 7 illustrate a case where the pressing plate (120, 121) is driven by the driving unit (130, 131), but as described above, the electrode pair (110, 111) can also be driven by the driving unit to enter the inside of the cavity, and even in this case, the same effect as described above can be obtained.

[0099] FIG. 8 is a drawing showing a schematic flow chart for explaining a method of operating a skin treatment device according to an embodiment of the present invention.

[0100] Referring to FIG. 8, the skin treatment device (1000) can suction a target area of ​​the skin into the cavity of the skin receiving cap (100) (S100). To this end, the skin treatment device (1000) can sense the negative pressure applied to the cavity through a predetermined pressure sensor and suction the target area of ​​the skin while increasing the negative pressure until it reaches a predetermined reference negative pressure.

[0101] Then, the skin treatment device (1000) can introduce a compression plate (120, 121) and / or an electrode pair (110, 111) (S110). Through this, the area of ​​skin in contact with the electrode pair (110, 111) can be increased.

[0102] After this, the skin treatment device (1000) can irradiate electric energy (pulse) (S120).

[0103] The above skin treatment device (1000) can continuously apply electric energy in a fixed state after the compression plate (120, 121) and / or electrode pair (110, 111) is moved in once, but as described above, the compression plate (120, 121) and / or electrode pair (110, 111) can also be repeatedly moved in and out at a certain frequency to apply physical pressure (S140).

[0104] And, when the skin temperature within the common area reaches a predetermined reference temperature (e.g., 42 degrees) through this process, the skin treatment device (1000) stops irradiating electric energy and also stops driving the compression plate (120, 121) and / or electrode pair (110, 111), thereby terminating the operation of the skin treatment device (1000) (S150).

[0105] Ultimately, according to the technical idea of ​​the present invention, when applying electric energy by sucking the skin, the treatment effect can be increased by increasing the area of ​​the skin in contact with the electrode, and the effect can be further increased by providing a massage effect through a physical external force.

[0106] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that the present invention can be readily modified into other specific forms without altering the technical spirit or essential characteristics thereof. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single component may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined manner. The scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
