Description

Technology Field

[0001] The present invention relates to a light source-based black ice removal device, a light source-based black ice removal system, and a control method for a light source-based black ice removal device. More specifically, the invention relates to a light source-based black ice removal device, a light source-based black ice removal system, and a control method for a light source-based black ice removal device for removing black ice on a road surface by controlling the radiant heat irradiation of light generated from a light source. Background Technology

[0002] Road surface conditions and driver visibility have the most significant impact on ensuring vehicle driving stability. For example, snow accumulation or frozen ice significantly reduces frictional resistance, while black ice—which forms when the road freezes due to condensation or sudden temperature drops following rainfall—is even more dangerous because it cannot be observed by the driver's naked eye.

[0003] In addition, when caused by a sudden temperature difference between the air and the ground, even in the absence of snowfall, water vapor in the air may freeze immediately upon contact with the ground, resulting in the formation of black ice as described above. At this time, fog may also be present, obstructing the driver's view and making it impossible to observe the black ice. This can lead to serious accidents on roads where high-speed driving takes place, such as highways, but there is currently no special alternative other than driver caution.

[0004] Various technologies have been proposed to provide a safe driving environment despite the rapidly changing road surface conditions due to weather conditions. For example, on roads designated as freezing risk zones, salt spraying facilities are installed to spray calcium chloride onto the road to lower the freezing point of the road surface and prevent freezing, or heating wires are embedded in the bottom of the road to apply current to the wires according to weather conditions to prevent freezing.

[0005] However, these brine spraying facilities have the problem that the brine containing calcium chloride can flow into adjacent farmland through the road surface, contaminating the soil, or get on moving vehicles and cause corrosion, and if brine is sprayed on civil engineering structures made of concrete such as bridges or retaining walls, it causes deterioration of the concrete, which reduces the durability of the facilities.

[0006] In addition, burying heating cables in roads has limitations in terms of economic feasibility, as not only is installation expensive, but excessive electrical energy is consumed during operation.

[0007] In order to solve these problems, the applicant filed and obtained the registration of the "anti-slip device for black ice on roads" under Korean Patent No. 10-2221831 (registered on February 23, 2021, hereinafter referred to as the "prior art document"). The aforementioned prior art document proposes a method for transmitting hot air through a blower pipe using a hot air production means and a blower fan, wherein the hot air is sprayed onto the road using pressure injection nozzles continuously provided in the blower pipe.

[0008] However, this hot air injection method has a limitation in that the pressure of the hot air discharged from the pressure injection nozzle drops significantly, preventing the hot air from reaching the opposite side of the road.

[0009] Accordingly, there has been a need for technology to remove black ice by irradiating radiant heat, in addition to methods such as brine spraying, hot air spraying, and burying heating wires. The problem to be solved

[0010] The objective of the present invention is to provide a light source-based black ice removal device, a light source-based black ice removal system, and a method for controlling the light source-based black ice removal device for removing black ice on a road surface by controlling the radiant heat irradiation of light generated from a light source. means of solving the problem

[0012] Here, the lens portion includes a first lens and a second lens, and the generated light is refracted through the first lens, gathered at the focal point of the first lens, and then spreads out, and is refracted again through the second lens to have a straight line.

[0013] In addition, the focal points of the first lens and the second lens are the same.

[0014] In addition, the reflector can be adjusted vertically and rotated left and right, and the processor can control the irradiation angle of the light in correspondence with the adjusted angle of the reflector and control the irradiation direction of the light in correspondence with the amount of left and right rotation of the reflector.

[0015] Additionally, the second lens can move in the direction of the focal length, and the processor can control the movement of the second lens to adjust the distance between the first lens and the second lens, and control the width of the light irradiation range corresponding to the adjusted distance between the first lens and the second lens.

[0016] In addition, the processor can calculate the temperature increase / decrease rate based on the temperature information, and can control at least one of the width of the light irradiation range and the irradiation angle in correspondence with the temperature increase / decrease rate.

[0017] In addition, the barrel housing including the lens portion can be extended or retracted in the vertical direction and rotated in the horizontal direction, and the processor can control the irradiation angle of the light in response to the vertical movement of the barrel housing and control the irradiation direction of the light in response to the amount of rotation of the barrel housing in the horizontal direction.

[0018] In addition, the light source unit includes a laser generator, and the generated light is a laser.

[0019] In addition, the first lens and the second lens may include a convex lens that refracts and converges the generated laser.

[0020] Meanwhile, a light source-based black ice removal system according to one embodiment of the present invention comprises a plurality of temperature sensors installed embedded in a road surface and a plurality of light source-based black ice removal devices installed embedded inside a concrete structure disposed on the road surface and irradiating light through an opening formed in the concrete structure. The light source-based black ice removal device may include a light source unit that generates light and emits it in a certain direction, a lens unit that refracts the generated light, a reflector unit that reflects the light refracted through the lens unit to irradiate it in a desired direction, a communication unit that receives temperature information of the road surface from each of the plurality of temperature sensors, and a processor that extracts an area where the temperature of the road surface is calculated to be below a preset temperature based on the temperature information, and controls the reflector unit so that the irradiation range of the light is positioned in the extracted area to transmit radiant heat through the light.

[0021] Meanwhile, a control method for a light source-based black ice removal device according to one embodiment of the present invention includes the steps of receiving temperature information of a road surface from each of a plurality of temperature sensors installed embedded in the road surface, extracting an area where the temperature of the road surface is calculated to be below a preset temperature based on the temperature information, and controlling a reflector so that radiant heat through the light is transmitted by positioning the irradiation range of light generated through a light source unit over the extracted area.

Specific details for implementing the invention

[0024] The present invention will be described in more detail below with reference to the drawings. Furthermore, in describing the present invention, detailed descriptions of related known functions or configurations are omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the invention. Additionally, the terms described below are defined considering their functions in the present invention, and these may vary depending on the intentions or relationships of the user or operator. Therefore, their definitions should be based on the content throughout this specification.

[0025] FIG. 1 is a diagram illustrating the configuration of a light source-based black ice removal device according to one embodiment of the present invention.

[0026] Referring to FIG. 1, a light source-based black ice removal device according to one embodiment of the present invention includes a light source unit (110), a lens unit (120), a reflection unit (130), a communication unit (140), and a processor (150).

[0027] Here, the light source-based black ice removal device (100) includes all devices having a form that transmits radiant heat by irradiating light generated from a light source unit (110) onto a desired area on the road surface, and this may include the configuration described above.

[0028] Specifically, the light source (110) can generate light and emit it in a certain direction, for example, it can generate and emit infrared light or a laser, which are types of invisible light. In the case of such types of invisible light, such as infrared light or a laser, it is not visible to the human eye but can enable heat transfer.

[0029] Here, the light described in this specification may include all light of the non-visible light series that exhibits linearity and radiates heat, and in particular, may include lasers.

[0030] That is, the light source (110) generates infrared or laser light, which is non-visible light, and emits it in a certain direction, and the emitted infrared or laser is irradiated onto a certain area through the reflection part (130) to be described later, and heat is transferred through the irradiated infrared or laser, and the heat transferred in this way is defined as a type of radiant heat.

[0031] In addition, the irradiation range described in this specification refers to the irradiation range of light generated from the light source unit (110), and the irradiation range of the light is defined as being the same as the irradiation range of radiant heat transmitted through the light.

[0032] Accordingly, infrared rays or lasers, which are a type of invisible light generated through the light source (110) but are invisible to the human eye, are irradiated onto a certain area of ​​the road surface, and radiant heat is transferred to the irradiated area, causing the temperature of the irradiated area to rise and thus removing black ice.

[0033] Meanwhile, the lens unit (120) can refract the generated light. Here, the lens unit (120) may include a plurality of lenses and can perform the function of refracting light that has the property of not spreading out and moving in a certain direction, such as a laser, to gather it to a single point and then spread it out again.

[0034] And, the reflector (130) can reflect the light refracted through the lens (120) so that it is irradiated in a desired direction.

[0035] This reflective part (130) can be implemented as a flat mirror and can perform the function of reflecting light refracted through the lens part (120) in a desired direction.

[0036] Additionally, the reflector (130) is connected to at least one actuator and is capable of moving in all directions. Here, an actuator refers to a mechanical device used to move or control a system, and is a term that includes, for example, a prime mover using electricity, hydraulics, compressed air, etc.

[0037] Meanwhile, the communication unit (140) can receive temperature information of the road surface from each of a plurality of temperature sensors installed embedded in the road surface. Here, the communication unit (130) can communicate with at least one of the temperature sensors, a server, and an external device, and can communicate with the server and the external device through various communication methods such as BT (Bluetooth), IoT (Internet of Things), WI-FI (Wireless Fidelity), Zigbee, IR (Infrared), Serial Interface, USB (Universal Serial Bus), LoRa (Long Range), LTE (Long Term Evolution), etc.

[0038] For example, the communication unit (130) can communicate with a cloud server and can be linked with all devices connected to the cloud server. Here, the communication unit (130) can transmit humidity information, camera recognition information, status and operation information of the light source-based black ice removal device (100), etc., to the server in addition to road surface temperature information obtained through a temperature sensor.

[0039] Meanwhile, the processor (150) can extract an area where the temperature of the road surface is calculated to be below a preset temperature based on temperature information, and control the reflector (130) so that the irradiation range of light is positioned for the extracted area so that radiant heat is transmitted through light.

[0040] Specifically, when temperature information is received from each of a plurality of temperature sensors embedded within the road surface, the processor (150) determines whether each of the received temperature information is below a preset temperature, detects the temperature sensor corresponding to the temperature information below the preset temperature, and can extract the area where the detected temperature sensor is placed.

[0041] Additionally, when temperature information is received from each of the multiple temperature sensors installed embedded within the road surface, the processor (150) can calculate the temperature of the area where the temperature sensor is not embedded based on the received temperature information.

[0042] For example, in an area where the first temperature sensor and the second temperature sensor are buried apart from each other, the processor (150) can calculate the area between the first temperature sensor and the second temperature sensor as the average of 3 degrees when the first temperature sensor is 2 degrees and the second temperature sensor is 4 degrees.

[0043] Additionally, the processor (150) may calculate the temperature of the road surface by calculating a correction value for the temperature information of the temperature sensor installed embedded within the road surface. Specifically, the processor (150) may calculate the temperature of the road surface by calculating a correction value that reduces the value by 10% for the temperature information of the temperature sensor installed embedded within the road surface.

[0044] Here, the correction value may change depending on wind speed, temperature, humidity, etc.

[0045] As described above, the temperature information of the road surface refers to the temperature information of the surface for both the area where the temperature sensor is installed and the area where the temperature sensor is not installed. The processor (150) can calculate the temperature of the area where the temperature sensor is installed as well as the area where the temperature sensor is not installed based on the temperature information of the temperature sensor installed inside the road surface, and can calculate the temperature of the road surface by calculating a correction value for the temperature information calculated in this way.

[0046] And, the processor (150) can extract an area where the temperature of the road surface calculated as described above is calculated to be below a preset temperature, and can control the reflector (130) so that the irradiation range of light is positioned for the extracted area so that radiant heat through light is transmitted.

[0047] Specifically, the processor (150) can control the reflector (130) to move through an actuator so that the reflector (130) can be positioned in an area where the light irradiation range is calculated to be below a preset temperature.

[0048] Accordingly, the irradiation range of light reflected through the reflector (130) is positioned in the area where the temperature of the road surface is calculated to be below a preset temperature, thereby allowing radiant heat to be transferred to the irradiation range, and thus allowing the temperature of the road surface to be maintained above a certain temperature, thereby preventing the creation of conditions where black ice can form on the road surface, or melting and removing the black ice that has formed.

[0049] Meanwhile, the lens unit (120) includes a first lens and a second lens, and the generated light is refracted through the first lens, gathered at the focal point of the first lens, and then spreads out, and is refracted again through the second lens to have a straight line.

[0050] FIG. 2 is a drawing illustrating the configuration of a lens part and a reflector part according to an embodiment of the present invention.

[0051] Referring to FIG. 2, the lens unit (120) includes a first lens (121) and a second lens (122), and light (10) generated from the light source unit (110) is refracted through the first lens (121), and the refracted light (11) is gathered at the focal point of the first lens (121) and then spreads out, and is refracted again through the second lens (122) to become light (12) that has straight-line propagation.

[0052] And, the light (12) that has a straight line is reflected by the reflector (130), and the reflected light (13) is irradiated in a desired direction.

[0053] Here, the focal points of the first lens (121) and the second lens (122) according to one embodiment of the present invention are the same.

[0054] FIG. 3 is a drawing illustrating the focus of a first lens and a second lens according to an embodiment of the present invention.

[0055] Referring to FIG. 3, light (11) refracted through the first lens (121) is gathered at the focal point (20) of the first lens (121), and the focal point (20) of the first lens (121) is the same as the focal point (20) of the second lens (122). Thus, the refracted light (11) gathered at the focal point (20) of the first lens (121) is spread out again, and the light (11) spread out from the focal point (20) of the first lens (121), that is, the focal point (20) of the second lens (122), can be refracted through the second lens (122) and changed into light (12) that has a straight-line propagation.

[0056] As described above, by utilizing the same characteristics of the focal point (20) of the first lens (121) and the focal point (20) of the second lens (122), light is collected through the first lens (121), dispersed, and refracted to have a straight line through the second lens (122), so that light can ultimately be directed in a desired direction through the reflector (130).

[0057] Meanwhile, the reflector (130) can be adjusted vertically and horizontally and rotated, and the processor (150) can control the irradiation angle of light in response to the adjusted angle of the reflector (130) and control the irradiation direction of light in response to the amount of left and right rotation of the reflector (130).

[0058] FIG. 4 is a drawing for explaining the movement of a reflector according to an embodiment of the present invention.

[0059] Referring to FIG. 4, the reflector (130) is connected to the reflector support (131) to enable vertical angle adjustment (410) and horizontal rotation (420), which can be implemented through a plurality of actuators provided inside the support (131).

[0060] In addition, when the reflector (130) shown on the left side of FIG. 4 forms an upward angle of, for example, 30˚, a straight-line light (12) can be reflected and irradiated by the reflector (130), and the reflection angle of such irradiated light (13) forms 30˚.

[0061] And, when the reflector (130) shown on the right side of FIG. 4 moves its angle in a slightly higher direction than the reflector (130) shown on the left side, that is, for example, when it forms 45˚ in the upward direction, light (12) that has straightness can be reflected and irradiated by the reflector (130), and the reflection angle of such irradiated light (13) forms 45˚.

[0062] That is, as the reflector (130) moves up and down and the vertical angle changes, the reflection angle of the light (13) irradiated through the reflector (130) also changes, and consequently, the irradiation angle of the irradiated light (13) can be changed.

[0063] Accordingly, the processor (150) can control the irradiation angle of the irradiation light (13) by adjusting the upper and lower angles of the reflector (130).

[0064] Additionally, the irradiation direction of the irradiation light (13) can be changed in correspondence with the amount of left and right rotation by the left and right rotation (420) of the reflector (130), and the processor (150) can control the irradiation direction of the irradiation light (13) by controlling the left and right rotation of the reflector (130).

[0065] Meanwhile, according to another embodiment of the present invention, the second lens (122) can move in the direction of the focal length, and the processor (150) controls the movement of the second lens (122) to adjust the distance between the first lens (121) and the second lens (122), and can control the width of the light irradiation range corresponding to the adjusted distance between the first lens (121) and the second lens (122).

[0066] FIG. 5 is a drawing for explaining the adjustment of the width of the irradiation range according to the movement of the lens part according to one embodiment of the present invention.

[0067] Referring to FIG. 5, the process of changing the width of the light irradiation range according to the change in the position of the second lens (122) is illustrated.

[0068] On the left side of FIG. 5, the width (520) of the illumination range of light (13) reflected through the reflector (130) is shown with the second lens (122) positioned so that the focal points of the first lens (121) and the second lens (122) are the same.

[0069] Additionally, on the left side of FIG. 5, the second lens (122) is shown in a positioned position in the focal length direction (510), that is, in the downward direction, and in this case, the focal points of the first lens (121) and the second lens (122) become different from each other.

[0070] Accordingly, the light (11) refracted through the first lens (121) is gathered at the focal point of the first lens (121), but the focal point of the first lens (121) is different from the focal point of the second lens (122), so the refracted light (11) is gathered between the focal point of the second lens (122) and the second lens (122) and then spreads out again, and as a result, the refracted light (11) is refracted by the second lens (122) in a state where it is not sufficiently spread out.

[0071] And, the light (12) that has a straight line through the second lens (122) is reflected through the reflector (130), and the width (530) of the irradiation range of the reflected light (13) is shown, and it can be seen that the width (530) of the irradiation range of the reflected light (13) is smaller than the width (520) of the irradiation range of the reflected light (13) shown on the left.

[0072] That is, as the second lens (122) moves downward (510) and approaches the focal point of the second lens (122), the width of the illumination range of the light (13) reflected through the reflector (130) becomes smaller.

[0073] Additionally, when the second lens (122) moves downward (510) and the distance between the first lens (121) and the second lens (122) decreases, the width of the illumination range of the light (13) reflected through the reflector (130) becomes smaller.

[0074] However, according to one embodiment of the present invention, even if the second lens (122) moves in the downward direction (510) and the distance between the first lens (121) and the second lens (122) is reduced, the second lens (122) can only move up to the focal point of the first lens (121), and the distance between the first lens (121) and the second lens (122) cannot be smaller than the focal distance of the first lens (121).

[0075] That is, the distance that the second lens (122) can move is also likewise limited to within the focal length of the second lens (122).

[0076] And, the processor (150) can adjust the distance between the first lens (121) and the second lens (122) by moving the second lens (122) within the distance at which the second lens (122) can move, and consequently, can adjust the width of the illumination range of the light (13) reflected through the reflector (130).

[0077] Meanwhile, the processor (150) can calculate the temperature increase / decrease rate of each of the plurality of temperature sensors based on temperature information received through the communication unit (140), and can control at least one of the width of the light irradiation range and the irradiation angle in response to the calculated temperature increase / decrease rate.

[0078] Specifically, the processor (150) can calculate the temperature increase / decrease rate of each of the plurality of temperature sensors, detect at least one temperature sensor among them that is calculated to have a temperature drop rate greater than a preset value, extract the area where the temperature sensor is placed, and cause light to be irradiated to the area.

[0079] Additionally, the processor (150) can increase the amount of radiant heat transferred per unit area by increasing the width of the irradiation range to increase the amount of light irradiated or by increasing the irradiation angle so that the irradiation range does not spread out, in order to increase the temperature in the area where at least one temperature sensor is placed and the rate of temperature decrease described above is calculated to be greater than a preset value, and can perform this simultaneously.

[0080] Of course, since the irradiation range does not increase based on the same amount of light energy, the amount of radiant heat transferred per unit area does not decrease simply because the irradiation range is widened; specifically, if the irradiation range increases, the light energy increases accordingly, and if the irradiation range decreases, the light energy decreases accordingly.

[0081] This is because when the distance between the first lens (121) and the second lens (122) is reduced, the light that is refracted and spread through the first lens (121) is refracted through the second lens (122) before it is sufficiently spread, and thus the light that takes on a straight line through the second lens (122) is reduced accordingly.

[0082] Meanwhile, the processor (150) can control at least one of the width of the light irradiation range and the irradiation angle to control the amount of radiant heat transferred per unit area in the irradiation range, thereby effectively removing black ice in the area where light is irradiated or effectively preventing the formation of black ice.

[0083] In addition, as described above, the barrel housing including the lens part (120) as well as the reflector part (130) can be extended or shortened in the vertical direction and can be rotated in the horizontal direction.

[0084] That is, the barrel housing including the first lens (121) and the second lens (122) can also be expanded or contracted in correspondence with the distance between the first lens (121) and the second lens (122), and as a result, the barrel housing can be expanded or contracted in the vertical direction.

[0085] In addition, the barrel housing itself can be rotated in the left and right directions, so that the same effect as the reflector (130) rotating in the left and right directions can be produced.

[0086] Accordingly, the processor (150) can control the irradiation angle of light in response to the up-and-down movement of the barrel housing and control the irradiation direction of light in response to the amount of left-and-right rotation of the barrel housing.

[0087] Meanwhile, a light source unit (110) according to one embodiment of the present invention includes a laser generating unit, and the light generated through the light source unit (110) may be a laser. Here, the laser may include a gas laser, a solid-state laser, a liquid laser, and a semiconductor laser.

[0088] In this way, the laser generated through the light source (110) has the property of traveling in a straight line in a certain direction without spreading, so it can spread through the first lens (121) and the second lens (122) and exhibit straightness.

[0089] In addition, the first lens (121) and the second lens (122) according to one embodiment of the present invention may include convex lenses that refract and converge the generated laser.

[0090] Meanwhile, a light source-based black ice removal system according to one embodiment of the present invention may include a plurality of temperature sensors and a plurality of light source-based black ice removal devices.

[0091] FIG. 6 is a drawing for explaining a light source-based black ice removal system according to one embodiment of the present invention.

[0092] Referring to FIG. 6, the light source-based black ice removal system (600) includes a plurality of temperature sensors (610) installed embedded in the road surface (30) and a plurality of light source-based black ice removal devices (620) installed embedded inside a concrete structure (630) placed on the road surface (30) and irradiating light (650) through an opening (640) formed in the concrete structure (630). Here, the light source-based black ice removal devices (620) may include a light source unit that generates light and emits it in a certain direction, a lens unit that refracts the generated light, a reflector unit that reflects the light refracted through the lens unit to irradiate it in a desired direction, a communication unit that receives temperature information of the road surface from each of the plurality of temperature sensors, and a processor that extracts an area where the temperature of the road surface is calculated to be below a preset temperature based on the temperature information, and controls the reflector unit so that the irradiation range of the light is positioned for the extracted area so that radiant heat through the light is transmitted.

[0093] In FIG. 6, a light source-based black ice removal device (620) can irradiate light (650) through an opening (640) formed in a concrete structure (630) onto an area (660) where a temperature sensor (610) is embedded, and it is assumed that the temperature of the road surface (30) measured by the temperature sensor (610) is measured to be below a preset temperature.

[0094] Of course, the light source-based black ice removal device (620) can irradiate light (650) to other areas through an opening (640) formed in the concrete structure (630), and as described above, can efficiently remove black ice by controlling the radiant heat transfer rate per unit area by controlling the width of the irradiation range and the irradiation angle.

[0095] In addition, although only one concrete structure (630) with a light source-based black ice removal device (620) installed is shown in FIG. 6, multiple such concrete structures (630) can be installed at regular intervals along the edge of the road surface (30).

[0096] Additionally, these concrete structures (630) can be implemented as dikes or curbs and can be placed not only at the edges of the road surface (30) but also in the central area of ​​the road surface (30).

[0097] Meanwhile, a light source-based black ice removal device (100) according to one embodiment of the present invention can measure the temperature of the road surface through a non-contact temperature measuring unit (not shown) provided in the light source-based black ice removal device (100) itself, without receiving temperature information of the road surface from each of a plurality of temperature sensors installed embedded in the road surface.

[0098] For example, a non-contact temperature measuring unit may be attached to or connected to a portion of the reflective unit (130), so that it can move in the same direction as the reflective unit (130) moves.

[0099] And, the non-contact temperature measuring unit moves in accordance with the movement of the reflector (130), thereby enabling non-contact temperature measurement over the irradiation range of the reflector (130).

[0100] Meanwhile, a control method for a light source-based black ice removal device according to one embodiment of the present invention may include the step of receiving temperature information of a road surface from each of a plurality of temperature sensors installed embedded in the road surface (S710), the step of extracting an area where the temperature of the road surface is calculated to be below a preset temperature based on the temperature information (S720), and the step of controlling a reflector so that radiant heat through the light is transmitted by positioning the irradiation range of light generated through a light source unit for the extracted area (S730).

[0101] In addition, the operation of the light source-based black ice removal device (100) and the operation process of the processor (150) described above can all be applied in the same way to the control method of the light source-based black ice removal device.

[0102] Meanwhile, a non-transitory computer-readable medium storing a program that sequentially performs the control method according to the present invention may be provided.

[0103] A non-transient readable medium refers to a medium that stores data semi-permanently and can be read by a device, rather than a medium that stores data for a short period of time, such as a register, cache, or memory. Specifically, the various applications or programs described above may be stored and provided on non-transient readable media such as CDs, DVDs, hard disks, Blu-ray discs, USBs, memory cards, and ROMs.

[0104] In addition, although the above-described block diagram illustrating a light source-based black ice removal device, which controls a reflector to transmit radiant heat through light by positioning the irradiation range of light over the extracted area based on temperature information received from each of a plurality of temperature sensors embedded in the road surface to extract an area where a temperature sensor is positioned where the temperature inside the road surface is measured to be below a preset temperature, does not show a bus, communication between each component of the light source-based black ice removal device may be performed via a bus. Furthermore, each device may additionally include a processor, such as a CPU or a microprocessor, that performs the various steps described above.

[0105] Furthermore, although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. It is understood that various modifications can be made by those skilled in the art without departing from the essence of the invention as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
