Detailed ways

The details of the present invention are described in order to facilitate an understanding of the embodiments of the present invention. However, those skilled in the art will recognize that the embodiments can be practiced in the absence of one or more specific details. , methods, materials, components, and the like, and the structures, materials, or operations are not specifically shown or described in detail to avoid obscuring or obscuring the embodiments of the present invention.

As shown in FIG. 1, the device of the present invention is independently installed in each door of the door. If the device is included in the production of the car, the device can be hidden in the door, and only two electrical switches are exposed, and the cost is It can also be much lower than the former. One of the two electric switches can immediately stop the prompt sound when pressed, and the other side push electric switch can turn off the function of the prompt sound.

The main function or feature of the present invention is that the signal or voice prompt is triggered only when the user opens the door from the vehicle compartment. The beep sounds and the prompt sound is automatically stopped when the door is closed.

A sub-function or feature of the present invention is that: When the prompt is triggered, the prompt sounds to stop immediately by pressing only one button. After the sound is stopped, the function of prompting the sound when the door is opened can be resumed without pressing the button.

The secondary function or feature 2 is: If the user in the car wants to avoid triggering the prompt when the door is opened, you can first press and hold the electric switch button in the retracted position, and then open the door with the opening door handle, when the door opens two This function can be achieved by pressing the electric switch button more than three centimeters and after the door handle is returned to its original position.

Five preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which respectively employ two basic circuits. Example 1:

It uses the basic circuit of the doorbell used in ordinary homes (Fig. 49 or Fig. 49A), and the IC of its circuit diagram (Fig. 49, Fig. 49A and Fig. 53) can use the IC used in the ordinary button doorbell sound box.

As shown in Figure 1, the front seat door of the car is equipped with a reminder body 1 covered with a large safety mat 10, a standard electric switch 装 2 with a small safety mat, and a permanent magnet small magnetic rod carrier 33 (attached to the driving door) The back of the handle 38), the permanent magnet magnet switch 匣22 and the permanent magnet strong magnet 43 (attached to the car floor). The main body of the reminder of the rear seat of the carriage is not equipped with a large safety mat, just to mark the upper part of each part. The permanent magnet magnet switch 安装 mounted on the bottom of the door is fixed to the bottom edge of the back of the prompter body. There is also a permanent magnet magnet 43 attached to the floor of the car as a magnetic source of the magnetoelectric switch.

The function and mounting method of each component will now be analyzed in detail. As shown in Fig. 3, the permanent magnet small magnetic bar carrier 33 is mounted on the back of the door handle 38, preferably about 10 mm from the end of the door handle. The permanent magnet small magnetic rod carrier has a color-developing scale line symmetrically dividing it for the purpose of visually aligning the standard electrical switch 匣21 within 5 mm below it. The standard electric switch of the invention can be selected from the model of the magnetic switch SD-8571 of Shenzhen Xinwei Electronics Co., Ltd. (SUNWAVE), and its thickness is only 4 mm. It is also possible to use the SD-8581 model with the cable from the end (Fig. 26) or other company's young tubular magnetoelectric switch for driving in a recess below. Door Handle. The standard electrical switch of the present invention is additionally provided with color development marks on both sides, which are about 3 mm from the end. The permanent magnet magnet switch 匣22 (Figs. 9 and 22) is an electric switch 加 with a super-strong permanent magnet. The north pole or the south pole of the ultra-fine permanent magnet 222 is the best magnetic receiving point on either side of the reed switch on the positive electric switch, and is fixed by the magnet sealing cover 223 (Fig. 21), so that the reed switch is often The current is turned on to form a magnetically closed normally closed switch. As shown in FIGS. 4 and 20, the permanent magnet small magnetic rod has a diameter of 2.4 mm and a length of 6 mm. The reed switch 212 (Figs. 17 and 25) in the standard electric switch 匣21 and the permanent magnet bar 32 (Fig. 19) in the permanent magnet bar 3 are filled with a synthetic glue. fixed. The length, width and thickness of the figure show that it is small, and the safety pad is more suitable for driving safety. Pulling the door handle of the permanent magnet small magnetic rod carrier in the car to drive the door can effectively transmit the magnetic switch to the standard electric switch 安装 installed under it, so that the reed switch has two conductive connections at a time.

The permanent magnet small magnetic rod carrier 33 and the standard electric switch 匣21 must not turn on the current of the reed switch 212 of the standard electric switch 匣21 when the door handle is not pulled after being installed; but pull the door to open the door There must be two times before and after the moment to make the reed switch turn on the current, because the effective magnetic field of the north pole or the south pole of the permanent magnet small magnetic rod 332 usually has two times back and forth across the standard electric switch within 5 mm below it. The tick position on one side. Installation They can also follow this principle in other types of door handles. Even small magnets can be removed for attachment to alternative door handles; however, such door handles must be unobtrusive.

As shown in Fig. 2, the prompter main body 1 is most preferably mounted on the lower side of the inner seat 39 on the inner door 39 of the vehicle compartment, because even if a traffic accident occurs and the vehicle body side is hit, it does not cause a passenger. hurt. The main body of the reminder is fixed on the door by four to six screws. If the door is not flat, the two fixing holes in the middle can be used (the two screw fixing holes of the main switch can also be two of the fixing holes).

The prompter main body 1 (Fig. 8) is a battery case 11 on the side and a stop button 161, a main electric switch box 5 and a sound box 12 on the other side. In addition to the battery position 111, the battery case 11 also has a sealed circuit board case 112 for sealing the circuit board case to enhance waterproof performance. When the door is opened on rainy days, the entire reminder has access to rain. But even the battery cover 114 Not enough to tighten, the infiltration of rain will only damage the battery.

The sealed circuit board box has six sets of two wires leading out. The first set of double wires 1121 is connected to the main switch box 5 via the battery case. The second set of wires 1122 is connected via a battery compartment to a standard electrical switch 匣 21 under the door handle. The third set of wires 1123 is led out of the battery case and connected to the permanent magnet magnet switch 匣 22 on the door near the door. The fourth set of wires 1124 is led out to the waterproof speaker 121 of the sound box 12 via the battery case. The fifth set of wires 1125 is connected to the permanent magnet magnetic normally closed switch 16 via the battery case. The five sets of wires are led out through five oblique holes, and the gaps at the exits of the five sets of wires are completely sealed with industrial glue. The sixth set of wires 1126 is connected to the 3V battery level 111. The inside of the battery compartment cover just prevents the two batteries from automatically slipping out. According to another embodiment of the present invention, a plurality of sets of lead wires may be disposed to be connected to the power source of the vehicle itself, and in this case, a flashing light that is lit when the prompt sounds may be added to enhance the prompting effect; The car burglaring sounder also illuminates when the ringing sounds.

The first set of double wires 1121 is connected to the main power switch box 5; it is an electric switch box with an electric switch push button, as an option to temporarily turn off the prompt sound function. Its connection in the circuit is not fixed because it is only an electrical switch box that can turn off the circuit.

The main power switch box 5 is a combination developed by the standard electric switch 匣 21 (Fig. 28). It includes a mains switch box top cover 52, an electrical switch push button 53, a main electrical switch box backplane, and a standard electrical switch 匣 21 (Fig. 27). The electric switch push button 53 (Figs. 27 and 31) includes a push button body 531, an ultra-fine permanent magnet 222 and a push button bottom cover 532 (Fig. 30), both of which are combined by ultrasonic bonding technology or industrial paste. The main switch box bottom plate and the standard electric switch 匣 21 are also made by ultrasonic bonding technology or industrial paste combination. The top of the upper switch box cover 52 has an open rail for the push button to be pushed. One of the center of the track has a narrow, slightly raised portion for locking the position of the electric switch push button in the open or closed position.

After the combination, when the electric switch push button is pushed to the middle of the upper cover of the main switch box (Fig. 29), the ultra-thin permanent magnet 222 of the push button can effectively make the reed switch in the standard electric switch 匣21. Turn on the circuit. If the push button is pushed to the end of the opening track of the upper cover of the main electrical switch box, the internal contacts of the reed switch are disengaged from the magnetic sense and are not connected. The second set of dual wires 1122 leads to a standard electrical switch 匣 21 (Fig. 3) that is connected below the drive door handle 38. A third set of dual wires 1123 leads to the permanent magnet magnet switch 匣 22 (Figs. 9 and 22). The permanent magnet magnet switch 匣 is preferably fixed to the door edge near the door of the car floor, and is reciprocally supported by the magnetic force of the permanent magnet magnet 43 which is fixed to the correct magnetic pole of the car floor and at an appropriate distance. The contact is separated; the current is terminated to stop the sound; it can also be fixed to other positions on the door near the door to be placed by the permanent magnets 43 near the door to produce the same magneto-electric switching effect. . A circular permanent magnet magnet has a colored mark on one side to indicate that it is a South or North Pole.

The permanent magnet magnet switch 22 of Fig. 42 is mounted on the bottom edge of the back of the prompter body, and the reminder body and the floor of the compartment have been positioned by a foam film at a distance of about 10 mm in the installation procedure, so the permanent magnet magnet The switch 匣 22 has been mounted approximately 10 mm from the floor of the carriage.

The upward magnetic pole of the permanent magnet magnet 43 of Fig. 42 must be opposite to the magnetic pole of the permanent magnet magnet of the permanent magnet magnet switch 向 which faces the side of the electric switch. If the ultra-strong permanent magnet 222 on the side of the reed switch is the north pole, the permanent magnet 43 magnet mounted under it must be in the south pole.

If the permanent magnets 43 move parallel in parallel to the side of the permanent magnet magnet switch 匣 without the permanent magnet, the distance between the two remains unchanged, and the permanent magnet 43 is reversed. The opposite poles are opposite each other, which produces the same magnetic effect; but to avoid confusion, only the former installation method is used.

Near the permanent magnet magnet switch 匣22, there are two magnet positioning members flat columns 17 and 171 (Fig. 7) under the front surface of the prompting body; the two flat columns are matched with the magnet positioning member 431 (for mounting permanent magnets and strong magnets for the car floor) Figure 48B1). The magnet positioning member 431 also has two small holes into which two small holes can be inserted into the sides of the two flat columns (Fig. 48B1 and 2 for mounting the permanent magnet strong magnet 43 on the floor of the passenger compartment). The positioning of the permanent magnet magnet 43 in the front view (left diagram) of Fig. 42 can be shifted to the left or right by a certain distance, preferably within 3 mm, and the side view (right side view) of the permanent magnet magnet 43 Can only be valid within the range indicated. The magnet magnet 43 may also be provided with a magnet sheath 432 (Fig. 43). If the door does not allow the body of the reminder to be installed under the door, it can be installed in other positions on the door, but it is best to install a safety pad as shown in Figure 1 (Figures 45 and 46).

The fourth set of dual wires 1124 is connected to the sound box 12 (Figs. 1, 7, and 12) via the battery compartment. The sound box includes a waterproof speaker 121, a sound box bottom plate 122, and a sound box cover 123 (Fig. 11). The bottom of the sound box bottom plate includes a very permeable grille, the wires can be connected to the waterproof speaker through the gap between the branches, and the front of the sound box cover is provided with a mesh hole for sound transmission. The sound box cover is fixed to the sound box bottom by screwing, snap fit, sliding fit, or bonding, so as to be easily removed, so that the sludge on the speaker can be removed with a small hair brush, because the sludge will hinder the sound. propagation.

The fifth set of double wires 1125 is connected to the permanent magnet magnetic normally closed switch 16 via the battery case (Fig. 14). This switch is used because it is absolutely waterproof, and ordinary normally closed switches cannot. The normally closed switch includes a standard electric switch box 21, a sound stop button 161, a strong permanent magnet magnet 162, a spring 163, and a sound stop button support cover 164. The stop button support cover is fixed by the pin 166 to the spring 163. After the combination, a part of the standard electric switch box is hidden in the concave position of the permanent magnet magnetic constant-close switch top plate portion 165; the sound-stop button support cover also has two longer pillars and a small portion is inserted into the other two recesses. Positioning. The stop button has a small hole to hide the strong permanent magnet 162 (Fig. 16); there are two missing positions on the side of the stop button to match the thicker part of the two longer struts of the stop button support cover (not shown in the figure), which prevents the stop button from rotating and the strong permanent magnet 162 under the thrust of the spring 163 to align with the best magnetization point on either side of the standard electrical switch box (Fig. 15), It constitutes a normally closed switch caused by a magnetic force. When the stop button is pressed to the end, the standard electric switch 匣 is released from the magnetic sense without being energized. By cutting off the current at the appropriate circuit point of the circuit, the next prompt beep will automatically start from the beginning when power is restored.

A flashing light 7 (Figs. 1, 7, and 9) that illuminates when the beep sounds can be added next to the stop button to enhance the prompting effect; just as some car burglars sound when the beep sounds, there is also a flashing light. However, it is best to use a power source from the car itself.

The entire function of this first embodiment will now be described. When the passenger pulls the door open from the compartment, the first is The effective magnetic field of the small magnetic bar on the handle of the door passes over the standard electric switch 匣, so that the internal contacts of the reed switch are separated by the instantaneous suction connection. This situation is the same as the moment when the visitor presses the doorbell outside the door to make the circuit contacts in the button have a momentary connection. But at the time the door was still not open or only slightly opened, so that the permanent magnet magnet switch on the side of the door 匣

The inner contact of the reed switch of 22 is still intercepted by the permanent magnet strong magnet 43 to cut off the critical connection point of the circuit, so the prompt sound will not be emitted; but when the passenger pushes the door open, the handle is opened and the rebound is made. When returning to the original position, the effective magnetic field with the small magnetic bar passes over the standard electric switch 匣; since the door is open enough at that time, the internal contact of the reed switch of the permanent magnet magnet switch mounted on the door of the door has been restored by itself. The ultra-fine permanent magnets are connected by a strong magnet, and the circuit is restored to the original, so the prompt sounds immediately.

When the sound box sounds, as soon as the door is closed, the sound will stop immediately, because the permanent magnets 43 will cut off the critical connection point of the circuit. Similarly, when the prompt sounds, as long as the stop button 161 is pressed to the end, the current through the permanent magnet magnetic normally closed switch is terminated, and the prompt sound is immediately stopped. If the passenger wants to open the door to avoid the prompt, you can first press and hold the button with two or three fingers at the same time, and then open the door with the other hand. When the door is opened two or three centimeters or more. And when the door handle is returned to the original position, the button is stopped and the button is completed. In addition, you can also choose to turn off the beep, just turn the electric switch push button 53 in the correct direction.

Example 2:

In this embodiment, a magnetic induction door opening sounder circuit (such as FIG. 50) is used. In addition to the circuit board, in addition to the circuit board, the permanent magnet magnetic bar 匣3 can be selectively replaced with the permanent magnet small magnetic bar carrier. The permanent magnet bar or permanent magnet small bar carrier can be mounted on the outside of the door handle (Figs. 32 and 34), and the standard electric switch 匣 21 is to be mounted in the lower 8 mm range; if necessary, Another safety pad can be added to cover the permanent magnet bar. For the mounting method, reference may be made to the mounting method of the permanent magnet small magnetic rod carrier 33 and the standard electric switch 匣 21.

The circuit of this embodiment makes it possible to sound a sound when the sound box and the reed switch and the permanent magnet magnet box are installed in the door, and the door does not stop the sound. In the circuit of this embodiment, two circuit points are connected. The sound of the sound box is hidden, and the sound can be resumed without being connected; the power will not be consumed if it is connected for a long time. In the present embodiment, the standard electric switch 匣21 mounted on the door near the door is connected to the two circuit points as a magnetic control switch to stop the prompt sound, and the mounting method is the same as that of the first embodiment. The floor of the compartment installed underneath is also a permanent magnet magnet 43, but it is not necessary to align the direction of the north and south of the magnet (Fig. 41). The permanent magnet magnet 43 of the front view (the left diagram) of Fig. 41 is allowed to deviate to the left or right within 3 mm, and the permanent magnet magnet 43 of the side view (the diagram to the right) can only be effective within the range indicated.

In terms of function, when the door handle of the car is pulled apart to separate the inner contacts of the reed switch of the standard electric switch 匣21 underneath, the circuit of the circuit board box is triggered, but if the door is not opened to the standard side of the door The switch 匣21 (the reminder body is installed close to the floor of the car, so that the standard electric switch 底部21 at the bottom is also located at the door side) is still connected to the reed switch, and the sound box still fails to sound. In other words, if the passenger in the compartment only pulls the door handle and deliberately pulls the door and does not push it open, the sound box will not sound. In fact, the circuit of the circuit board box has been triggered, and the sound is suppressed. When the prompt sounds, the door is closed, and the sound stops immediately, but the set sounding process continues until the set sounding content is completed. The rest of the first sub-function is exactly the same as the former. The second sub-function is to first press the button with one finger and not open it, then open the door with the other hand. When the door is opened for more than two or three centimeters, the button is pressed to complete. This saves the conditions after the door handle returns to its original position.

Example 3:

Also using the circuit board circuit of Embodiment 2, the entire circuit will now be shown in FIG. The permanent magnet small magnetic rod carrier installed on the back of the driver's door handle is exactly the same as that installed in the first embodiment, but the permanent magnet magnet switch 匣22 is installed under the door handle instead of the standard electric switch 匣21. . The downward magnetic poles of the permanent magnet small magnetic rod carrier 33 are arranged to properly match the magnetic poles of the ultra-fine permanent magnets 222 in the permanent magnet magnet switch 22, the magnetic pole pairs of the two permanent magnets The magnetoelectric switching device mounted on the side of the door of the first embodiment was the same as the prompting of the prompting to stop. The circuit of this embodiment causes the speaker to sound only when its magnetoelectric switch changes from connected to disconnected, and the restoration of the connection does not stop the sounding. The permanent magnet magnet switch 匣22 installed under the handle of the driving door constantly connects the circuit, and the effective magnetic field of the permanent magnet small magnetic rod 332 installed on the back of the driving door handle can make the permanent magnet magnet switch 匣22 dry when passing. The reed contact has a connection from the connection to the disconnection, because the magnetic fields of the upper and lower permanent magnets 332 and the permanent magnet 222 compete, but this can make the ringing; although the permanent magnet is small The effective magnetic field has to pass through the permanent magnet magnet switch twice, and it will not affect the effect.

The standard electric switch 匣21 installed on the door of the car near the door and the permanent magnet strong magnet 43 installed on the floor of the car are exactly the same as those in the second embodiment, so the door must be pressed to suppress the sound, due to the circuit operation of the two. The effect is exactly the same, so the first sub-function is exactly the same as the former. However, the second sub-function needs to be operated by the method of Embodiment 1 because the driving door handle and the effective magnetic field with the permanent magnet small magnetic rod returning to the original position pass over the permanent magnet magnet switch 匣.

Example 4:

Although the circuit of Embodiment 2 or Embodiment 3 is basically the same, the connection method of the circuit (Fig. 52) is slightly modified. The installation method of the portion of the door handle is exactly the same as that of the embodiment 3. The change is only in the permanent magnet magnetic constant-closed switch 16 circuit in series with a magnetically controlled normally closed switch. At the same time, the magnetic switch of the embodiment 2, 3 is connected by connecting two circuit points to stop the door. The permanent magnet magnet switch 匣22 disposed on the door near the door and the permanent magnet strong magnet 43 fixed to the floor of the car are the series of magnetron normally closed switches, because closing the door enables the permanent magnet to be electrically switched. 22 is not powered. The magnetron switch installed at the door side is identical to the one in the first embodiment.

The function of this embodiment will now be described. When the door is opened, the driving door handle is pulled so that the effective magnetic field of the permanent magnet small magnetic rod carrier 33 on the back side is swept twice in the range of 5 mm of the permanent magnet magnet switch 匣5 mm. The first time it passed the permanent magnet magnet switch 匣22 failed to make the prompt sound, because the door is still not open, the circuit is in a truncated state. But when it passes the permanent magnet magnet switch 第二 for the second time, the door is enough to open the magnetron switch on the side of the door.

The contact connection of the (permanent magnet magnet switch 匣 22), the circuit is restored, and the prompt sound is emitted.

This embodiment is more energy-efficient, because the current of the prompter is terminated when the door is closed; unlike the second embodiment and the third embodiment, when the door is closed, the sounding stops, but the set sounding process continues, until the setting The final sounding content ends.

The prompt sounding function in this embodiment is the same as the former, and the method of Embodiment 1 or Embodiment 3 must be employed to perform the second secondary function described above.

Looking at Embodiments 1-4, if the present invention is installed on a future automobile, a permanent magnet small magnetic bar for opening the door handle can be provided in the opening handle of the door, as shown in Fig. 37. The standard electric switch or permanent magnet magnet switch can be hidden in the proper position under the door handle.

The former body of the reminder is restricted to be mounted on the door on the lower side of the seat of the car; otherwise, a safety pad is added. However, if the door has such a device, its setting position is not limited, and the stop button can be placed beside the door of the door to facilitate the use of the first and second sub functions. And the power can come from the battery of the car itself (of course, after voltage reduction). It is also possible to add a flashing light that illuminates when the prompt sounds on the door inside the compartment to enhance the prompting effect, just as some car burglaring sounders also illuminate when the sound is sounding.

When the invention is embedded in a car, it is only necessary to expose the stop button of the permanent magnet magnetic constant-close switch and the push button of the main electric switch box. It can withstand the most extreme weather temperatures, even if it is flooded, it will not be damaged; it will not cause flammable gas explosion.

Example 5

Many business taxis have equipment that is opened and closed by the driver's button. In order to install a device that sounds in front of the vehicle, in addition to installing the aforementioned door device, another device activated by the driver is installed. The device turns on the electrical switch 201 of the other circuit (Fig. 53) while the driver is starting the metering meter. The circuit and the door sound box circuit of the first embodiment are all modified by a common doorbell circuit used by the public. But the electrical switch connection method of the two is different.

Before the passengers boarded the car, the driver button opened the door and the passengers boarded the car. However, when the passenger boarded the vehicle, the driver also activated the meter by charging the button of the other electric switch 201 (Fig. 53). When the passenger arrives at the destination and the passenger pays the fare, the driver will open the door and release the passenger. When the taxi meter stops beating, it is still in the starting state. Therefore, the driver button opens the door and the passenger gets off the vehicle. The normally open switch 202 of the circuit device triggers the prompting sound; when the driver button closes the door, the normally closed switch 203 button of the circuit device is simultaneously activated to stop the prompt sounding. Then, the driver will return the meter to the un-started state and also turn off the sound box.

The circuit device also has a design to prevent explosion of flammable gas. Its normally open switch 202 is housed in the center of a cylindrical small sealed box 2021 (Fig. 39). The small box has a screw cap 2023 that is tightened. A shaft 2024 passes through the center of the cover and the vertical bearing 2025 is directed to the normally open switch button. The lower portion of the shaft is secured by a small ring 2027, and the top end of the shaft is tightly inserted into a short cylindrical push button 2026. The small ring and button lock the shaft between the bearings of the cover, allowing the shaft to move up and down. When the cover is screwed, pressing the button is a button that presses the normally open switch. Therefore, even if a flammable gas surrounds the screwed small box, the extremely small amount of spark generated by pressing the button does not ignite the flammable gas outside the box.

Similarly, the normally closed switch 203 of the circuit arrangement is also housed in the center of a cylindrical, but bulky, sealed enclosure 2031 (Fig. 38). Since the two cartridges have the same construction principle, even if the cartridge is surrounded by flammable gas, the button 2036 that presses the cartridge does not ignite the flammable gas outside the cartridge.

The main body of the circuit device is a sound box, and the circuit is the circuit of FIG. The power can come from the battery of the car itself (of course, it must be reduced voltage). The sound box can be installed in any position in the car that makes a loud sound during the broadcast. Of course, the device must also take into account the safety of driving. The sound box has two sets of wires, and the first set of wires is made up of a sound box. When the circuit (Fig. 53) is led to the electric switch 201 and the button that is connected at the same time as the start of the metering meter, the normally open switch 202 is connected at the same time, and the two switches are connected in series. The wires are led out from points X and Z in the circuit diagram. The electric switch 201 can be turned on by the driver to turn on the X-point and Y-point in the circuit diagram.

The normally open switch 202 is connected from the Y point and the Z point in the circuit diagram, and is hidden in the small cylindrical case described above. When the driver pushes the button to open the door, the button can be activated to make the sound box sound prompt. Of course, if the driver does not start the meter, it will not trigger the prompt. The second set of wires are connected from the W and Z points in the circuit diagram to the normally closed switch 203 in the larger cylindrical case. When the driver button is closed, the button 2036 can be activated to stop the prompting in the broadcast.

Embodiment 1-4 The normally closed switch in the circuit diagram uses a permanent magnet magnetic normally closed switch 16. In the fifth embodiment, the normally closed switch that is sealed into the sealed cylindrical container can be used, because the displacement of the stop button is not as easy to install as the former.

The above description of the embodiments of the present invention, including the description of the present invention, is not intended to be exhaustive or to limit the invention. The specific embodiments and examples described herein are merely illustrative, and various equivalent modifications or applications can be made within the spirit and scope of the invention, as indicated. Such improvements and applications of the present invention are possible in accordance with the above description of the embodiments of the present invention, and such modifications and applications are intended to be included within the spirit and scope of the invention.
