Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bio-

TECHNICAL FIELD The present invention relates to a biosurfactant system for removing microorganisms, chemical agents, and the like present in the air in an automobile by using ultraviolet rays, and a method of sterilizing the same.

Recently, various viral avian influenza and bacterial infectious diseases have occurred, and life threatening of many animals is frequently occurred, and some problems of human infection are also occurring. It is not easy to defend against the spread of microorganisms that have already occurred, by constructing various preventive systems and spraying disinfectants in areas where infection is expected.

Microorganisms are small organisms that can not be observed by the naked eye and generally include fungi, protozoa, bacteria, viruses, algae, and the like. One of the widely used means of eradicating microorganisms is ultraviolet ray (UV). Ultraviolet (UV) energy has been used since the early 1900s to kill bacteria and microorganisms. When a sufficient amount of ultraviolet energy is applied, ultraviolet energy can kill microorganisms very effectively. However, when the ultraviolet light level is low and the uniformity of the ultraviolet radiation is insufficient, the ultraviolet ray sterilization effect is remarkably lowered. On the other hand, resistance to ultraviolet rays differs from organism to organism, and some organisms are more resistant to ultraviolet than other organisms. In particular, some organisms that form endospores and are in the semi-dormant state show strong resistance to ultraviolet light. Endogenous spores are known to resist considerably more sterilization techniques including heat, chemicals, x-rays and ultraviolet light.

Conventional ultraviolet sterilization systems have not been able to efficiently and effectively utilize ultraviolet energy to destroy airborne contaminants such as microorganisms below a certain level. Therefore, there is a need for a high energy ultraviolet sterilization system that can have a uniform distribution needed for the most effective process of disinfecting microorganisms in dangerous air and destroying other contaminants.

This problem is also the case in a limited space such as a car. The automobile basically has an air conditioning system for air purification. An air conditioner of an automobile includes an air intake port exposed to the outside so as to introduce outside air, an air circulation motor for sucking outside air through the intake port, an air purifying filter for filtering dust and the like from the introduced air, To an internal space of the vehicle. Air filters can filter out contaminants with sizes greater than fine dust, but they do not filter out microorganisms or chemicals.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail with reference to the drawings.

1 and 2, an automotive biosurfactant system 100 according to the present invention is installed in an automobile 10 and includes an ultraviolet sterilizer 110, a chemical agent filter unit 130, a sensor unit 150, And an air pollution monitor 170. The air pollution monitor 170 is connected to an electronic control unit (ECU) 11 of the automobile 10.

Ultraviolet Sterilizer

The ultraviolet sterilizer 110 may be implemented as a part of the automotive interior air conditioner 13 or may be provided as a separate device following the internal air conditioner 13. [ The ultraviolet sterilizer 110 may be manufactured separately from the air pollution monitor 170 or may be manufactured integrally with the air pollution monitor 170.

The ultraviolet sterilizer 110 is generally installed in a form buried without being exposed to the interior space of the automobile. Preferably, an ultraviolet sterilizer 110 is provided in parallel with an air purification filter (not shown) so as to constitute a part of the internal air conditioning apparatus 13 of the automobile 10 as described above, or an ultraviolet sterilizer (110) may be provided. Further, in consideration of the structure of the automobile 10, it is desirable that the ultraviolet sterilizer 110 is designed to be mountable and detachable for replacement and repair.

The ultraviolet sterilizer 110 forms a path of air that is sealed, and uses ultraviolet rays to sterilize microorganisms in the air. To this end, the present invention proposes a structure of the ultraviolet sterilizer 110 that can significantly increase the intensity and uniformity of ultraviolet energy (UV energy) in the ultraviolet sterilizer 110, thereby providing a very high and uniform ultraviolet dose .

The ultraviolet sterilizer 110 includes a main body 210 forming a sealed internal space 210a, a reflector 215 provided on an inner wall of the internal space 210a, And an ultraviolet lamp 231 for irradiating the ultraviolet ray.

The main body 210 forms a closed internal space 210a and the internal space 210a forms a path through which the air flows in accordance with the internal air conditioning apparatus 13 of the automobile, . The ultraviolet sterilizer 110 sterilizes the microorganisms present in the air flowing into the internal space 210a to discharge the cleaned air. An ultraviolet lamp 231 is embedded in the internal space 210a of the ultraviolet sterilizer 110 to sterilize microorganisms in the air.

The main body 210 is provided in the form of a tube or a pipe, and has an input unit 211 and an output unit 213 at both ends thereof. The input unit 211 is provided toward the intake port (not shown) of the automotive air conditioner 13 and the output unit 213 is provided toward the exhaust port (not shown) of the automotive air conditioner 13, Is introduced into the internal space 210a through the input unit 211 and purified, and then discharged through the output unit 213 to the internal space of the vehicle. The input unit 211 and the output unit 213 are implemented by, for example, a flat panel to seal the internal space 210a, a plurality of intake through holes 211a through which air is introduced into the input unit 211, A plurality of exhaust through holes 213a through which the internal air is discharged are formed in the portion 213. Since the input unit 211 and the output unit 213 are functionally named based on the air flow and the air does not flow in only one direction, the input unit 211 and the output unit 213, Can also be changed.

Since sterilization of an organism depends greatly on the amount of ultraviolet energy transmitted to the organism, sufficient and effective sterilization in the ultraviolet sterilizer 110 is required to be performed at any arbitrary point in the ultraviolet sterilizer 110, Roughness or dose is required. The present invention utilizes a chamber structure to realize an ultraviolet radiation dose of at least 75,000 cd / m 2 at any arbitrary position in the ultraviolet sterilizer 110, preferably at least 100,000 cd / Cm < 2 > is effective. The maximum amount of ultraviolet radiation irradiated to the microorganisms introduced into the ultraviolet sterilizer 110 varies depending on the residence time of the air. Assuming that the air stays less than 2 seconds in the ultraviolet sterilizer 110 in a state in which ultraviolet rays of 75,000 cps / cm 2 are irradiated, the ultraviolet sterilizer 110 irradiates the inflow air with an ultraviolet radiation dose of at least 150,000 cps / . ≪ / RTI > Here, the ultraviolet ray irradiation amount is a measurement of ultraviolet ray energy per unit area for microorganisms, such as UV energy density (E) using ㎼ · sec / ㎠ as a unit.

The ultraviolet illuminance in the ultraviolet sterilizer 110 is naturally influenced by the illuminance of the ultraviolet lamp 231 itself but is not sufficient as the illuminance of the ultraviolet lamp 231 itself, It is difficult to make a space of uniform illumination because it decreases sharply according to the distance. Particularly, in the case of an automobile, since the electric power to be used is limited, it is difficult to make sufficient illuminance by the ultraviolet lamp 231 itself.

In order to solve this problem, in the present invention, a reflection plate 215 is installed on the entire inner wall of the main body 210. The sealed body 210 and the reflection plate 215 accumulate and intensify the ultraviolet energy in the internal space portion 210a together with the effect of blocking the ultraviolet energy emitted from the ultraviolet lamp 231. [ The ultraviolet sterilizer 110 of the present invention can increase ultraviolet light intensity in the ultraviolet sterilizer 110 from 10 times to almost 50 times as compared with the case where only a simple ultraviolet lamp is used and uniformity of illumination is also improved.

The ultraviolet lamp 231 may be provided with a reflector such as normal lighting, but such reflector is installed in the lamp and is not installed in the entire space. The reflector 215 of the present invention is installed on the entire inner space 210a which is a closed space. It is preferable that the reflector 215 is installed at 95% or more, preferably 99% or more of the entire surface area of the inner wall of the main body 210.

It is preferable that the reflection plate 215 can scatter and / or reflect ultraviolet rays emitted from the ultraviolet lamp 231 by 95% or more. The reflection plate 215 may be formed by a method of attaching a panel of a material having an ultraviolet reflection characteristic or applying a paste of a material having a reflection characteristic to the inner wall of the ultraviolet sterilizer 110, Mirror) may be installed. For example, the reflector 215 can be implemented with mirror-polished aluminum or chemically polished and anodized aluminum material.

The size and the number of the intake through holes 211a and the exhaust through holes 213a of the main body 210 affect the residence time of the air and may affect the ultraviolet energy accumulating ability in the ultraviolet sterilizer 110. [ For example, the ratio of the intake through hole 211a in the input unit 211 and the exhaust through-hole 213a in the output unit 213 are respectively less than 40%, so that the stay of the air in the ultraviolet sterilizer 110 It is necessary to increase the time, for example, to be less than 10% so as to improve the air retention time and the energy accumulation efficiency.

The ultraviolet lamp 231 uses ultraviolet rays in the band of 220 to 300 nm and can use a low-pressure mercury discharge lamp that emits ultraviolet rays continuously and narrowly banded. The ultraviolet lamp 231 is fixed to the outside of the ultraviolet sterilizer 110 through the fixing-through hole 210a formed in the wall of the main body 210 or the end panel.

The ultraviolet lamp 231 receives operating power from the air pollution monitor 170. The electric power provided by the air pollution monitor 170 to the ultraviolet lamp 231 is preferably a constant electric power of the automobile supplied from a generator (not shown) of the automobile or directly from an automobile battery (not shown).

A photo sensor 151 connected to the air pollution monitor 170 and measuring the ultraviolet illuminance inside the ultraviolet sterilizer 110 is installed in the internal space 210a of the main body 210. [ The air pollution monitor 170 controls the ultraviolet light intensity of the ultraviolet light sterilizer 110 to be equal to or larger than a predetermined reference size or within a reference range using the measured value of the photosensor 151.

The operation of the ultraviolet sterilizer 110 is controlled by the air pollution monitor 170. As described below, the ultraviolet sterilizer 110 basically operates only when the automobile 10 is in operation, and the operation of the ultraviolet sterilizer 110 is also stopped when the automobile is turned off. The control of the air pollution monitor 170 should take these points into consideration.

Chemical agent filter section

The chemical agent filter 130 filters chemical agents contained in the air flowing into the automobile interior space. A chemical agent is a chemical agent that is used for the purpose of killing or neutralizing a person or an animal through a physiological effect, and is a toxic chemical agent. Chemical agents include nerve agents that act on the nervous system of the human body, vagal agents that cause severe pain and inflammation in the skin / eyes / mucosa, vaginal bleeding agents and vaginal agents.

The chemical agent filter 130 includes at least one chemical agent filter. Each chemical agent filter has a different chemical agent that can be filtered or decrypted. Therefore, the chemical agent filter unit 130 must have a plurality of chemical agent filters in accordance with the chemical agent selected as the object to be treated.

The chemical agent filter unit 130 is preferably implemented as a part of the automotive air conditioner 13. The chemical agent filter unit 130 is disposed to face the input unit 211 at the front end of the ultraviolet sterilizer 110 or at the rear end of the ultraviolet sterilizer 110 213, respectively. On the other hand, since the chemical agent filter unit 130 does not use any electric power, it is not necessary to receive operating power from the air pollution monitor 170 or the automobile 10. [

The sensor unit

The sensor unit 150 includes at least one photosensor 151 and a biosensor 153 and is connected to the air pollution monitor 170.

The photosensor 151 is installed in the internal space 210a of the ultraviolet sterilizer 110 and the air pollution monitor 170 measures ultraviolet light intensity using the photosensor 151. [

The biosensor 153 is a sensor for detecting microorganisms in the air and can detect the concentration of microorganisms in the air and can identify the microorganisms in the air. Therefore, according to the configuration of the biosensor 153, You may. 3, the biosensor 153 of the present invention may be a combination of a plurality of sensors.

The biosensor 153 may be installed at various points in the interior space of the vehicle. For example, (1) regardless of the installation position of the ultraviolet sterilizer 110, the biosensor 153 of the interior space of the vehicle can be installed to monitor air contamination in the interior space of the vehicle. (2) In addition, the biosensor 153 may be installed in front of the input unit 301 in which the sterilizer 101 is installed and in front of the output unit 213 to check the operation state of the sterilizer 101 It is possible.

As described above, if the ultraviolet sterilizer 110 is designed to operate only when the automobile 10 is in operation while the automobile 10 is not operating normally, if the automobile 10 is operated for a predetermined time or longer, Can be introduced into the inner space. Therefore, it is necessary for the driver to check the state of microorganisms in the interior space of the vehicle before boarding or after boarding, so that installation by the method (1) may be necessary.

According to an embodiment, the sensor unit 150 may further include at least one chemical agent detection sensor 155. [ The chemical agent detection sensor 155 detects a specific chemical agent in the air. In the case of the chemical agent detection sensor (155), since the chemical agent that can be detected per sensor is different, in order to detect various chemical agents, a combination of detection sensors corresponding to the agent is required.

However, since the chemical agent filter unit 130 does not use any electric power, it operates at all times irrespective of whether the vehicle 10 is operated or not. Therefore, it is not necessary to dispose the chemical agent detection sensor 155 inside or outside the automobile 10, or at the front end or the rear end of the chemical agent filter section 130. Nevertheless, in the case of being disposed on the outside of the automobile 10 or on the input side of the chemical agent filter unit 130, the need can be examined in that the chemical agent can be detected in the air and displayed to the driver. Further, since the vehicle 10 is not a completely enclosed space, it is also conceivable that the vehicle interior space may be contaminated at any time.

Air pollution monitor

The air pollution monitor 170 is connected to the ultraviolet sterilizer 110 and the sensor unit 150 to control the overall operation of the automotive biosurfactant system 100 of the present invention.

3, the air pollution monitor 170 includes a power source unit 301, a sterilizer driving unit 303, a sensor receiving unit 305, an ECU interface 307, and a control unit 310. The air pollution monitor 170 includes an ultraviolet sterilizer 110).

The power supply unit 301 receives the constant power from the constant power supply of the automobile and controls the power supply according to the operation mode of the air pollution monitor 170. The power supply unit 301 may be connected to a junction box (not shown) in which various kinds of fuses of an automobile are built, or may be connected to a power line of an automobile. In any case, it is preferable that the power source unit 301 is connected to a constant power source to which power is supplied even when the vehicle is not turned on.

The sterilizer driving unit 303 supplies the power supplied from the power source of the automobile at all times to the ultraviolet lamp 231 of the ultraviolet sterilizer 110 and controls the power supply according to the control of the control unit 310 and controls the ultraviolet lamp 231 And a voltage to be supplied.

The automobile power supply is usually DC + 12V. When the key input of the automobile is located at the first stage (ACC), electric power is supplied to the accessory of the vehicle such as the radio. When the key input is located at the second stage (ON), the head lighter, Power is supplied to the control unit (ECU) and the like. The second stage at this time supplies power to the entire vehicle, but uses the battery power of the vehicle as in the first stage. If the vehicle key input enters the third stage (START) and the vehicle is started, the vehicle key input returns to the second stage. At this time, the vehicle operates by the power generated from the generator in the vehicle.

Considering the power consumption of the ultraviolet lamp 231, the ultraviolet sterilizer 110 can not use the first stage (ACC) power and preferably uses the generator power after the start of the vehicle. However, in exceptional cases, the automobile battery power can be used as the emergency power according to the embodiment described below.

The sensor receiving unit 305 is connected to the sensor unit 150 to supply the required power to the sensor unit 150 and reads the measured value of the sensor unit 150. The photosensor 151 and the biosensor 153 are connected to the sensor receiving unit 305 and the chemical agent detecting sensor 155 is connected to the sensor receiving unit 305 as necessary. The sensor receiving unit 305 provides the control unit 310 with ultraviolet light intensity, the number and concentration of microorganisms, the presence or absence of a chemical agent, and a concentration measurement value using the measured values of the sensor unit 150.

The sensor receiving unit 305 includes a plurality of connection terminals to which the biosensor 153 is connected and the photosensor 151, the plurality of biosensors 153, and the chemical agent detection sensors 155 ).

The ECU interface 307 is an interface capable of transmitting and receiving data or messages such as 'special sterilization-event' with the electronic control unit 11 of the vehicle 10, and corresponds to an interface held by the electronic control unit 11. [ The ECU interface 307 may be a serial communication system or a simple contact signal system. In the following description, it is to be understood that the transmission of data and the like between the air pollution monitor 170 and the electronic control unit 11 is performed through the ECU interface 307 even if not described.

Meanwhile, when the air pollution monitor 170 is connected to an external server (not shown), it may further include another network interface (not shown). For example, the network interface is a wireless network unit that can connect to a network (not shown) such as the Internet. The network interface provides status information to an external server under the control of the controller 310 and transmits control commands and the like, ).

The controller 310 controls the overall operation of the air pollution monitor 170 of the present invention. The control unit 310 includes a mode control unit 311, a sterilizer control unit 313, and an event monitoring unit 315 to perform the air pollution monitoring characteristic of the present invention.

The mode control unit 311 controls the operation mode of the air pollution monitor 170. The operation mode of the air pollution monitor 170 is divided into a 'normal operation mode' using the electric power of the generator of the automobile and a rest mode in which the power supply of the automotive generator is stopped. The normal operation mode is a state in which the vehicle 10 is running due to startup, and the idle mode is a state in which the vehicle is not started. The power supplied to the power supply unit 301 due to the ignition of the vehicle is not the generator power of the automobile but the battery power of the automobile. In both the normal operation mode and the idle mode, the power supply unit 301 receives the power of the automotive generator or the battery power at all times and supplies the power to the air pollution monitor 170 as operating power.

The mode control unit 311 may determine whether or not the vehicle is in a running state using the information provided by the electronic control unit 11 and may determine whether the vehicle 10 is in a running state, It is possible to judge whether or not the vehicle is started by checking the voltage of the terminal to which the voltage is outputted.

The sterilizer controller 313 controls the operation of the ultraviolet sterilizer 110 using the sterilizer driver 303 and monitors the operation of the ultraviolet sterilizer 110 based on the measured value of the biosensor 153. The sterilizer control unit 313 enters the normal operation mode and controls the sterilizer driving unit 303 to operate the ultraviolet sterilizer 110. [ When the mode is switched to the dormant mode, the sterilizer control unit 313 causes the sterilizer driving unit 303 to stop supplying power to the ultraviolet lamp 231. [

The event monitoring unit 315 generates a special sterilization event according to a predetermined condition and performs a special sterilization operation for a predetermined period of time. The sterilization event is basically generated when the air pollution monitor 170 starts operating as the automobile starts operating or is turned on.

Hereinafter, the operation of the automotive biosurfactant system 100 according to the present invention will be described focusing on operations of the sterilizer control unit 313 and the event monitoring unit 315. FIG.

Sterilization Control 1

In connection with the control of the ultraviolet sterilizer 110, the sterilizer control 313 controls the overall operation of the UV sterilizer 110 via the sterilizer driver 303 during the normal mode of operation. When the mode controller 311 switches the operation mode of the air pollution monitor 170 from the idle mode to the general operation mode, the sterilizer control unit 313 causes the sterilizer driver 303 to supply the ultraviolet lamp 231 with electric power And the ultraviolet lamp 231 is turned on to start the basic sterilizing operation.

The sterilizer controller 313 controls the sterilizer driver 303 such that the ultraviolet illuminance is maintained within a predetermined range in the ultraviolet sterilizer 110 while measuring the ultraviolet illuminance using the measured value of the photosensor 151 installed in the ultraviolet sterilizer 110 ) Controls the power supply to the ultraviolet lamp (231).

According to the embodiment, the sterilizer control unit 313 can provide the status information to the external server or the electronic control unit 11 of the automobile if the ultraviolet illuminance output from the ultraviolet lamp 231 does not fall within a predetermined value range . Also, the sterilizer control unit 313 can change the control method according to the control of the electronic control unit 11 of the external server or the automobile.

Example: Special Sterilization - Disinfection Control by Event

Hereinafter, the sterilization operation of the automotive bios sterilization system 100 according to the special sterilization-event will be described with reference to FIG.

<Special sterilization according to the start of the general operation mode - Event generation: S401 to S409>

When the mode control unit 311 changes the operation mode of the air pollution monitor 170 from the idle mode to the general operation mode in step S401, the sterilizer control unit 313 controls the sterilizer driving unit 303, The event monitoring unit 315 measures the concentration of the microorganisms in the interior space of the vehicle through the plurality of biosensors 153 and detects the concentration of the microorganisms in the monitoring space, (S403, S405, S407).

If it is determined in step S405 that the concentration of the microorganisms is equal to or higher than the reference value or a specific microorganism is detected, the event monitoring unit 315 generates a special sterilization event (S409).

According to the embodiment, in steps S403 to S407, the event monitoring unit 315 detects whether a specific chemical agent is introduced into the interior space of the vehicle through the chemical agent detection sensor 155, and when the specific chemical agent is detected, Sterilization-event.

<Special sterilization - Disinfection by event: S411>

The event monitoring unit 315 performs a special sterilization operation for a predetermined time according to the special sterilization-event. First, the event monitoring unit 315 requests the electronic control unit 11 to forcibly switch the air conditioning mode of the vehicle to the 'internal circulation mode'. The air conditioning modes of the vehicle include an internal circulation mode and an external circulation mode. The outer circulation mode is a mode for introducing the outside air into the interior space of the vehicle, and the inner circulation mode is a mode for blocking the inflow of outside air and circulating air in the interior space of the vehicle only. The adjustment of the automotive air conditioning mode may be performed by the control of the driver or may be determined according to the predetermined driving mode. If the existing air conditioning mode was the external circulation mode, it is forcibly switched to the internal circulation mode.

When the air conditioning mode of the vehicle is switched to the internal circulation mode by the electronic control unit 11, air in the interior space of the vehicle is repeatedly circulated in the bios sterilization system 100 in a state where the inflow of outside air is blocked. An air circulation motor (not shown) of the automotive air conditioner can control the air circulation.

After forcibly switching to the internal circulation mode, the electronic control unit 11 ignores the vehicle air conditioning mode control command (switching to the external circulation mode) from the driver without accepting it.

&Lt; Special sterilization - Determination of release of the event: S413 and S415 >

The event monitoring unit 315 repeatedly measures the concentration of microorganisms in the interior space of the vehicle through the biosensor 153 by repeating step S407 to return the concentration of the microorganisms in the monitoring space to a predetermined range, (S413). If it is determined in step S409 that the concentration of the microorganism has returned to the predetermined range and the microorganism has been removed, the event monitoring unit 315 cancels the special sterilization-event (S415).

Likewise, if a chemical agent is detected and a special sterilization-event has occurred, the event monitoring unit 315 detects whether the specific chemical agent is removed from the interior space of the vehicle through the chemical agent detection sensor 155 in steps S409 and S411 , Even if such special sterilization - events can be lifted.

&Lt; Recovery of automobile air conditioning mode: S417, S419 >

When the special sterilization-event is released, the event control unit 310 requests the electronic control unit 11 to release the forced air conditioning mode switching of the vehicle (switching to the internal circulation mode). Thereby, the electronic control unit 11 releases the forced switching of the automotive air conditioning mode to the internal circulation mode. When the forcible conversion is canceled, the automotive air conditioning mode may be returned to the mode selected by the driver, and the mode switching control of the driver may be accepted and processed (S417).

The operation mode of the air pollution monitor 170 maintains the normal operation mode (S419).

In this way, a warning event of the system 100 of the present invention is performed.

Meanwhile, when the air pollution monitor 170 is turned off during the normal operation mode, the apparatus enters a rest mode using battery power. The sterilizer control unit 313 turns off the ultraviolet lamp 231 to stop the ultraviolet sterilization operation . Nevertheless, the event monitoring section 315 can be provided with a special sterilization-event from the electronic control unit 11.

Event is provided from the electronic control unit 11 to the sterilizer control unit 313 and the sterilizer control unit 313 controls the sterilizer control unit 313 to turn on the ultraviolet lamp 231 To perform a special sterilization-event by performing an ultraviolet sterilization operation. Although the automobile battery power source is used as the idle mode, it is to start the ultraviolet disinfection in advance.

The special sterilization-event provided by the electronic control unit 11 can be generated, for example, by the remote control control before the driver boarding. At this time, the remote control of the driver becomes an air pollution monitor 170 and a special sterilization-event generation command of a predetermined type. When the special sterilization-event is received from the driver, the electronic control unit 11 switches the internal power supply to the second stage (ON) even when there is no key input, switches to the internal circulation mode in the air circulation mode, So that the air can be circulated internally.

On the other hand, the remote control of the driver may be an operation start command of the air pollution monitor 170, not the air pollution monitor 170 and the special sterilization-event generation command of a predetermined type. In such a case, the air pollution monitor 170 performs the same operation as that shown in FIG. 3 according to the operation start command of the electronic control unit 11. [ Even in this case, the electronic control unit 11 switches the internal power supply to the second stage (ON) even if there is no key input.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
