Description

Additive effects system and method for multiple projections

Technical Field

The present invention relates to a multi-projection (multi-projection) add-on effect system and method, and more particularly, to an add-on effect system and method, which can configure the direction of an add-on effect differently in association with a change of an image projected on a plurality of projection planes.

Background

Conventionally, in order to reproduce images such as movies, advertisements, and the like, two-dimensional images are projected on a single screen disposed in front of a theater. However, viewers under such systems can only view two-dimensional (2D) images.

Recently, a three-dimensional (3D) image technology for providing a viewer with a 3D image has been developed. The 3D image technique uses the principle of: when different images are presented to the left and right eyes of a viewer and combined in the brain, the viewer is enabled to feel a 3D effect even from a flat image. In detail, two cameras equipped with different polarization filters are used during photographing, and a viewer wears glasses with the polarization filters so that different images are presented to the left and right eyes during viewing.

However, although these 3D technologies may provide 3D images to viewers, the viewers only view images reproduced on a single screen, which may reduce the input level of the images. Further, the direction of the 3D effect perceived by the viewer is limited to the direction of a single screen.

In addition, according to the conventional 3D technology, a viewer must wear glasses equipped with a polarization filter during viewing, which may be inconvenient for the viewer, and different images are artificially presented to the left and right eyes, which may cause some sensitive viewers to feel dizzy or nausea.

Therefore, a so-called "multi-projection system" has been proposed, which can solve the problems of the conventional projection system based on a single screen. "multiple projection system" refers to a technique in which: a plurality of projection surfaces are arranged around the auditorium such that a synchronized image is reproduced on the plurality of projection surfaces, thus providing the auditorium with a three-dimensional effect and an immersive sensation.

Furthermore, it is necessary to provide characteristics that can be associated with multi-projection to additional effects (e.g., sound, wind, smell, etc.) other than images to maximize the 3D effect and immersion that viewers can feel from a "multi-projection system". However, there is no technique for additional effects that may be associated with multiple projection systems.

Accordingly, there is a need to develop a system that can provide additional effects (e.g., sound, wind, odor, temperature, etc.) in a new viewing angle associated with a "multi-projection system" that includes multiple projection surfaces.

The side effect system may change an output direction of sound associated with a corresponding object through the two or more speakers when the object in the image moves between the projection surfaces.

When the environment in the image relatively changes between projection surfaces, the side effect system may change the output direction of the sound associated with the corresponding environment through the two or more speakers.

When a specific event in an image occurs only on a specific projection surface among the plurality of projection surfaces, the bonus effect system may output a sound associated with the event only from a speaker installed in a direction of the specific projection surface.

Detailed Description

Hereinafter, a system and method for multi-projection additive effects according to the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided only for illustrative purposes so that those skilled in the art can sufficiently understand the spirit of the present invention, but the present invention is not limited thereto. Further, it should be understood that all matters shown in the accompanying drawings are to be interpreted as illustrative and may be in a form different from those of an actual implementation.

Next, an additional effects system according to the present invention will be described with reference to fig. 1 to 8.

Referring to fig. 1 and 2, the bonus effect system according to the present invention may include a plurality of projection surfaces 300 installed in a single theater, two or more bonus effect devices 100 implementing a bonus effect other than images projected on the plurality of projection surfaces, and a bonus effect management device 200 controlling the two or more bonus effect devices 100.

Here, the additional effect device 100 may configure the direction of the additional effect differently according to the images projected on the plurality of projection surfaces 300.

Further, it is preferable that two or more of the additional effect devices 100 are installed in a single theater, and the directionality of the additional effect can be variously achieved by the operation configuration of the two or more of the additional effect devices 100.

Multiple projection surfaces 300 are provided for multiple projections in a single theater. Multiple images may be rendered on multiple projection surfaces 300. Here, the images reproduced on the plurality of projection surfaces 300 may be synchronized with each other based on the synchronization signal. In this case, it is preferable that the images reproduced on the plurality of projection surfaces 300 generally generate a uniform image. In detail, although different images can be reproduced on the respective projection surfaces 300, it is preferable that the different images be associated with each other to generate a unified image when viewed on the entire projection surface.

Of course, according to embodiments, individual images (e.g., a primary image, a descriptive image for a primary image, etc.) may be projected on multiple projection surfaces 300.

Further, the plurality of projection surfaces 300 may be arranged not to be parallel to each other. According to the related art, an image is projected only on a screen disposed in front of a theater so that a viewer views an image reproduced on a two-dimensional screen, or a 3D technique is applied to the image itself reproduced on a plane. In contrast, according to the present invention, the plurality of projection surfaces 300 are three-dimensionally arranged so as not to be parallel to each other, and therefore a three-dimensional image having a high three-dimensional effect and an immersive sensation can be provided to the viewer through the three-dimensionally arranged plurality of projection surfaces 300 without applying a 3D technique to the image itself.

Further, it is preferable that the plurality of projection surfaces 300 are arranged around auditoriums in a theater. Accordingly, the viewers can feel as if they are in the space generated by the synchronized images reproduced on the plurality of projection surfaces 300, and thus the three-dimensional effect, the immersion, and the virtual reality felt by the viewers can be maximized.

In addition, the angle between the projection surfaces 300 is not limited to a specific angle, and the plurality of projection surfaces 300 may be arranged at various angles as long as the viewer can feel the three-dimensional effect.

In addition, the plurality of projection surfaces 300 may be arranged adjacent to or spaced apart from each other, even in this case, it is preferable that the plurality of projection surfaces 300 are arranged around the auditorium.

Fig. 6 is a diagram showing an example in which a plurality of projection surfaces are arranged on the front side, the left side, and the right side with respect to an auditorium, fig. 7 is a diagram showing an example in which a plurality of projection surfaces are arranged on the front side, the left side, the right side, and the top side with respect to an auditorium, and fig. 8 is a diagram showing an example in which a plurality of projection surfaces are arranged on the front side, the left side, the right side, the top side, and the bottom side with respect to an auditorium.

Further, the plurality of projection surfaces 300 may be constituted by various types of projection surfaces 300 such as a screen, a wall, and the like, and may include different types of projection surfaces 300 at the same time.

Further, the images reproduced on the plurality of projection surfaces 300 may be projected by two or more projection apparatuses installed in a theater, which may be implemented by variously including an optical system and a heating unit. For example, the projection device may be implemented in various ways, such as with a Cathode Ray Tube (CRT), with a Liquid Crystal Display (LCD), by Digital Light Processing (DLP) with a Digital Micromirror Device (DMD) chip, by liquid crystal on silicon (LcoS), and so forth. Further, two or more projection devices may be electrically connected to the image management device and then integrally controlled by the image management device, and images may be projected on the plurality of projection surfaces 300 under the control of the image management device.

Further, the operation of reproducing the synchronized image on the plurality of projection surfaces (multi-projection operation) may not be performed throughout the entire running time, but may be performed only at a specific scene or a specific timing. For example, basically, an image may be projected on only a single projection surface (main projection surface), and then a multi-projection effect may be achieved on a plurality of projection surfaces only at a specific time point or a specific scene (e.g., a battle scene, a fire scene, a climate change, etc.).

Of course, the operation of rendering the synchronized images on multiple projection surfaces may be performed throughout the run time.

The bonus effect device 100 is a device for realizing a bonus effect other than images projected on a plurality of projection surfaces 300. In particular, the additive effects device 100 is a device that adds an effect that increases the visual sense of realism or adds an effect that can be perceived by other senses than vision to increase the sense of immersion and sense of realism that viewers can perceive while viewing a multi-projection image. The additional effects that can be provided by the additional effects device 100 may include a sound effect, a wind effect, a smell effect, a fog effect, a temperature change effect, a laser effect, a light effect, a bubble effect, a water spray effect, a vibration effect, etc., and various effects associated with five senses of a human. Thus, the supplemental effects device 100 can include various devices that can simulate human five senses, such as speakers, blowers, fragrance diffusers, aerosolizers, heaters, coolers, laser devices, bubble generators, LEDs, water jets, vibrating devices, and the like.

In addition, two or more of the bonus effect devices 100 may be installed in a single theater. In particular, two or more of the bonus effects devices 100 may be installed near a plurality of projection surfaces 300 as shown in fig. 1, or may be installed at each auditorium as shown in fig. 2. Alternatively, some may be mounted near the plane of projection and some may be mounted near the auditorium.

In addition, it is preferable that the additional effect device 100 is installed at a place where the viewer can optimally feel the corresponding additional effect according to various properties of the achieved additional effect. Specifically, in the case of the bubble effect, the viewer can feel the effect optimally when the bubble generator is installed near the projection surface, and in the case of the water spray effect, the viewer can feel the effect optimally when the water spray is installed near the auditorium. Therefore, it is preferable that the additional effects device 100 is disposed at a place where the viewer can optimally feel the corresponding effect.

Further, it is preferable that two or more of the supplementary effects devices 100 are arranged in the same direction as the plurality of projection surfaces 300, because supplementary effects matching the directions of the plurality of projection surfaces 300 can be achieved by this arrangement.

The two or more additional effects devices 100 may change the direction of the additional effect in association with a change in the viewpoint of the multi-projection image projected on the plurality of projection surfaces 300.

For example, two or more of the supplemental effect devices 100 may change the direction of the supplemental effect as the object in the image moves between the projection surfaces 300. Referring to fig. 3, when an object (vehicle) in a multi-projection image moves from a left projection plane (a) to a middle projection plane (B) and then to a right projection plane (C), two or more additional effect devices 100 may change the direction of an additional effect (e.g., wind). In particular, as an object in an image moves between projection planes (a → B and B → C, visually switching between projection planes), two or more additional effect devices 100 may change the direction (indicated by an arrow in the drawing) of an additional effect (e.g., wind) according to the moving direction of the object, and thus may maximize the sense of realism and the sense of immersion felt by a viewer by the change of the direction of the additional effect. At this time, other additional effects (e.g., a sound effect, a smell effect, etc.) may be provided according to the moving direction of the object in addition to the wind effect. When various additional effects are provided by two or more additional effects devices 100 according to the moving direction of the object in the above-described manner, it is advantageous that the sense of realism and the sense of immersion perceived by the viewer can be maximized.

Further, when the environment (e.g., weather, fire, etc.) in the image relatively changes between the projection surfaces 300, the two or more additional effect devices 100 may change the configuration of the direction of the additional effect. Referring to fig. 4, when an environment (e.g., fire, etc.) in an image relatively changes between a left projection plane, a middle projection plane, and a right projection plane, two or more additional effect devices 100 may change a configuration of directions of additional effects (e.g., temperature changes). In particular, when a fire (a) existing only on the left projection plane spreads to the right projection plane (C) via the middle projection plane (B), two or more of the supplementary effects devices 100 may configure the direction of the supplementary effect differently. For example, in the case of a, the two or more additional effect devices 100 may generate high-temperature heat only in the vertical direction of the left projection plane, in the case of B, the two or more additional effect devices 100 may generate high-temperature heat in the vertical direction of the left projection plane and the middle projection plane, and in the case of C, the two or more additional effect devices 100 may generate high-temperature heat in the vertical direction of all three projection planes. Thus, two or more of the supplemental effect devices 100 can provide a change in the configuration of the direction of the supplemental effect, thereby maximizing the sense of realism and the sense of immersion perceived by the viewer.

In addition, when a specific event in an image occurs only on a specific projection plane among the plurality of projection planes 300, the two or more additional effect devices 100 may implement the corresponding additional effect only in a direction starting from the corresponding projection plane. Referring to fig. 5, when a specific event (e.g., a change in the state of an object in an image, a change in the environment in an image, etc.) occurs only in an image on a left projection plane (a), only in an image on a right projection plane (B), or only in an image on a middle projection plane (C), two or more additional effect devices 100 may implement an additional effect only in directions from the respective projection planes. Accordingly, when a specific event occurs only on a specific projection surface, the viewer can recognize an additional effect (e.g., temperature change, smell, sound, etc.) associated with the specific event along with the directivity, and thus can feel maximized sense of reality and immersion.

Further, the two or more additional effect devices 100 may change the configuration of the direction of the additional effect through various methods that may be associated with the change of the viewpoint of the multi-projection image, in addition to the above-described methods.

Further, two or more of the bonus effect devices 100 may change the direction of the bonus effect by selective operation. For example, the supplemental effect device 100 may be mounted in various orientations that are implemented and selectively operated to change the configuration of the direction of the supplemental effect.

Further, two or more of the bonus effects devices 100 may adjust the intensity of the bonus effects in addition to the direction.

For example, when reproducing a scene of a match, two or more of the bonus effect devices 100 may generate low-temperature heat (e.g., 20 ℃), and when reproducing a scene of a fire on a hill, two or more of the bonus effect devices 100 may generate high-temperature heat (e.g., 40 ℃). Further, when reproducing a scene in which an airplane passes, the two or more additional effect devices 100 may adjust the intensity of the additional effect such that stronger wind is generated than in the case in which a vehicle passes.

In addition, the two or more additional effects devices 100 may adjust the intensity of various types of additional effects (sound, smell, fog, laser, light, bubbles, water spray, vibration, etc.) according to the image, in addition to these additional effects such as heat, wind, etc.

The bonus effect management apparatus 200 is an apparatus that controls two or more bonus effect apparatuses 100.

The bonus effect management device 200 may be electrically connected to two or more bonus effect devices 100 to control the respective bonus effect devices 100. Further, the bonus effect management device 200 may preferably be connected in parallel to two or more bonus effect devices 100 to control each of the bonus effect devices 100 simultaneously or individually. Further, the bonus effect management apparatus 200 may be connected to two or more bonus effect apparatuses 100 in a wired or wireless manner.

Further, the additional effect management device 200 may transmit a control signal to each additional effect device 100 to control the operation of each additional effect device 100, eventually changing the configuration of the direction of the additional effect. The control signal may include time information data and operation information data. The time information data may include information of a point of time at which each device is to operate, and the operation information data may include detailed operation information (output intensity, output type, etc.). More specifically, the time information data may be time information at which an image of a specific scene is to be displayed, and the operation information data may be detailed operation information (output type, direction, intensity, etc.) of a device that is to be operated at the image of the specific scene. Accordingly, each of the additional effects devices 100 can be synchronized with other additional effects devices 100 and images projected on the plurality of projection surfaces 300 based on the time information data, and an appropriate additional effect that can match a multi-projection image can be realized. Further, it is preferable that the time information data is generated based on a time code of the multi-projected image content so that each of the bonus effects devices 100 can be easily synchronized with the multi-projected image content. Further, the additional effect management device 200 may selectively operate two or more additional effect devices 100 based on the control signal, and this selective operation may change the configuration of the direction of the additional effect.

Further, the added-effect management apparatus 200 may be implemented using various electronic apparatuses. For example, the additional effect management apparatus 200 may be implemented in a single server or in a manner that two or more servers are interconnected. Further, the added-effect management apparatus 200 may be implemented in such a manner that a server and other electronic apparatuses are interconnected, or implemented in an arithmetic unit other than the server.

Further, the added effect management apparatus 200 may be configured in the form of an integrated management apparatus combined with an image management apparatus, which integrally controls two or more projection apparatuses. In particular, an integrated management device that can perform all functions of the image management device and the additional effects management device 200 may be configured (preferably, in the form of a server) to control the projection device and the additional effects device 100. Here, the integrated management device may synchronize two or more projection devices with two or more bonus effect devices 100 based on a common synchronization signal, and may be connected to the respective devices in parallel to control the respective devices simultaneously or individually.

Further, when the added effect management apparatus 200 is connected to an image management apparatus to constitute an integrated management apparatus, the integrated management apparatus may correct image contents to be projected by two or more projection apparatuses and enable the corrected image contents to be projected on a plurality of projection surfaces 300 through the two or more projection apparatuses.

Here, the integrated management apparatus may correct the image content based on information about two or more projection apparatuses or information about a plurality of projection surfaces 300. In this case, it is preferable that correction of the image content is performed to compensate for a difference in properties (brightness, color, image quality, material, structure, etc.) of the plurality of projection surfaces 300 or a difference in properties (lamp output, resolution, etc.) of the two or more projection devices (so as to generate a synchronized and unified image on the plurality of projection surfaces).

First, correction of image content performed by the integrated management apparatus based on information on the plurality of projection surfaces 300 will now be described. The integrated management apparatus may correct the image content based on the information on the properties of the plurality of projection surfaces 300. In particular, the integrated management device may correct image content to compensate for property differences (e.g., chromaticity differences, luminance differences, reflectivity differences, etc.) between the projection surfaces 300 based on information regarding the property differences.

Representatively, correction based on information about a chromaticity difference between the projection surfaces 300 will now be described (the process to be described below is of course applicable to correction based on a luminance difference, a reflectance difference, and the like). First, the integrated management apparatus may calculate information on the chromaticity difference between the projection surfaces 300 based on the chromaticity information of the respective projection surfaces 300. In detail, the integrated management apparatus may set a single reference projection plane and then calculate information on relative chromaticity differences of the respective projection planes. For example, information on the relative chromaticity difference is calculated in such a manner that: "the red (R) tone scale of projection plane a is higher than the reference projection plane by 50, the green (G) tone scale is higher than the reference projection plane by 40, and the blue (B) tone scale is the same as the reference projection plane". After the information on the chromaticity difference of the respective projection surfaces is calculated in this way, the image may be corrected based on the information calculated in this way, so as to, for example, "reduce the R gradation of the image projected on the projection surface a by 50, reduce the G gradation by 40, and maintain the B gradation". Therefore, the chromaticity difference of the projection plane can be compensated.

Further, the analysis of the property difference of the plurality of projection surfaces 300 may be performed in various ways in addition to the method of setting the reference projection surface. For example, representative values (e.g., mean, median, mode, etc.) of properties of the plurality of projection surfaces 300 may be calculated, and then relative property differences may be analyzed based on the calculated representative values.

Further, correction of image content performed by the integrated management apparatus based on information on two or more projection apparatuses will now be described. The integrated management device may correct the image content based on the information regarding the properties of the projection device. In particular, the integrated management device may correct image content to compensate for property differences (e.g., contrast differences, brightness differences, resolution differences, image quality differences due to physical distances, etc.) between two or more projection devices based on information regarding the property differences.

Representatively, correction based on information about a difference in luminance between two or more projection devices will now be described (the process to be described below is of course applicable to correction based on a difference in contrast, a difference in resolution, a difference in image quality, and the like). First, the integrated management device may compensate for a brightness difference between the projection devices by correction. For example, if it is assumed that the brightness of projection device a is 500ANSI lumens, the brightness of projection device B is 1000ANSI lumens, and the brightness of projection device C is 1500ANSI lumens, then the brightness difference can be compensated for by image correction. In detail, the luminance ratio of the images projected by the projection device A, B and C is corrected to 3:2:1, thereby compensating for the heterogeneity of the images that may occur due to the luminance difference between the devices.

Next, a specific embodiment of the added effects system according to the present invention will be described with reference to fig. 9 to 11.

Although the additional effect may be configured in various ways as described above, the wind effect, the sound effect, and the vibration effect will be described below.

Referring to fig. 9, the additive effect system may implement a wind effect by two or more blowers a-f distributed in a theater and change the direction of the wind according to multi-projection images.

For example, when an object in a multi-projection image moves between projection surfaces (a → B → C), the additive effect system can dynamically change the direction of the wind to the direction in which the object on each projection surface moves. In particular, when an object (e.g., an airplane) in an image moves rightward on the projection plane a, the additional effect system may generate wind matching the moving direction of the corresponding object by operating the blower a. Further, when an object in an image is switched to the projection plane B and moves rightward on the projection plane B, the additional effect system may change the direction of wind to a direction matching the moving direction of the corresponding object by operating the blower c. In addition, when an object in an image is switched to the projection plane C and moves rightward on the projection plane C, the additional effect system may change the direction of wind to a direction matching the moving direction of the corresponding object by operating the blower e.

In addition, if it is assumed that the object in the image of fig. 9 moves to the left, the additional effect system may realize a wind effect matching the moving direction of the object in the image by sequentially operating the blowers f, d, and a. In addition to these methods, the side effects system can change the direction of the wind effect in various ways.

Further, even when the environment in the image relatively changes between projection surfaces, the side effect system can change the configuration of the wind direction by two or more blowers. For example, when the weather environment (e.g., tornado) in the image relatively extends in the direction of the projection plane a → B → C, the additional effects system can change the configuration of the wind direction by the operation of the blowers a-f in the figure and other blowers (not shown).

Referring to fig. 10, the additional effects system may implement sound effects through two or more speakers a-f distributed in a theater and change the direction of sound according to multi-projection images.

For example, when an object in a multi-projection image moves between projection surfaces (C → B → A), the add-on system may change the direction of the sound associated with the corresponding object. In particular, when an object (e.g., a bird) in an image appears on the projection plane C, the bonus effect system may output a sound associated with the corresponding object through the speakers e and f. When an object (bird) in the image moves to the projection plane B, the bonus effect system may output a sound associated with the corresponding object through the speakers c and d. Further, when an object (bird) in the image moves to the projection plane a, the bonus effect system may output a sound associated with the corresponding object through the speakers a and b. Therefore, the direction of the position of the object in the multi-projection image can be matched with the direction of the sound of the object by these operations.

Furthermore, when the environment in the image changes relatively between projection surfaces, the side effect system may change the direction of sound through two or more speakers. For example, when an explosion occurs on the projection plane a of fig. 10 and an explosion occurs again in the projection plane C, the additional effect system may change the output direction of the sound associated with the explosion (output sound from the speakers a and b to output sound from the speakers e and f).

In addition, when a specific event in an image occurs only on a specific projection surface among a plurality of projection surfaces, the bonus effect system may output a sound associated with the event only through speakers arranged around the corresponding projection surface. For example, when a battle scene is reproduced only on the projection plane B of fig. 10, the bonus effect system may output sounds associated with the battle through only the speakers c and d. Thus, the directionality of sound matching the visual direction of the event in the image can be achieved.

For reference, the additive effects system may install speakers at various locations of a theater. For example, the additive effects system may mount speakers in various locations of a theater, such as the periphery of multiple projection surfaces, the ceiling, behind auditorium, and so forth. Accordingly, the present invention can provide a three-dimensional sound effect to a viewer, thus maximizing the immersion feeling felt by the viewer.

Referring to fig. 11, the additional effect system may implement a vibration effect by two or more vibration devices distributed in a multi-projection theater, and change the direction of vibration according to multi-projection images. Here, it is preferable that two or more vibration devices are installed on the floor of the multi-projection theater.

For example, when an event associated with the occurrence of vibration (e.g., an earthquake, ice break, movement of an object such as a train, etc.) occurs in the multi-projection image, the side effect system may change the direction of the vibration to the direction in which the occurred event occurred. In this case, the side effect system may sequentially vibrate the floor-mounted vibrating plate in a direction matching the direction in which the event occurred, and such sequential vibration may change the direction of the vibrating effect. Referring to fig. 11, when ice is broken in a direction such as B → a, the vibration device sequentially vibrates (e.g., a1 → a2 → a3 → a4 → B1 → B2). Thus, the present invention can utilize these vibrating devices distributed across the floor to provide the audience with maximum realism and immersion.

Next, an additional effect method according to an embodiment of the present invention will be described with reference to fig. 12.

Referring to fig. 12, the additional effect method according to the embodiment of the present invention may include the steps of: a step (S10) of projecting the images on a plurality of projection surfaces installed in a single theater and realizing additional effects other than the images.

Here, the additional effects may include a sound effect, a wind effect, a smell effect, a fog effect, a temperature change effect, a laser effect, a light effect, a bubble effect, a vibration effect, and the like, and various effects associated with five senses of a human.

After step S10, the images projected on the plurality of projection surfaces will change (S11). For example, an object in an image may move between projection surfaces, an environment in the image may relatively change between projection surfaces, or a specific event may occur on a specific projection surface among a plurality of projection surfaces.

When the images projected on the plurality of projection surfaces have been changed in step S11, the configuration of the direction of the additional effect may be changed according to the change in the images (S12).

Here, it is preferable that the change of the direction of the additional effect and the visual change of the direction of the multi-projection image are performed in such a manner as to match each other and be synchronized with each other.

Therefore, the additional effect method according to the present invention can provide additional effects of various directivities matching the visual change of the direction of the multi-projection image, thus providing the viewer with maximized three-dimensional effect and immersion feeling.

Further, the side effect method may be implemented in the form of a program and then stored in a recording medium readable by an electronic device, or transmitted and received through a communication network. Further, the side effect method may be implemented in the form of a program and then temporarily or permanently stored in various electronic devices.

In addition, the above-described side effect methods according to the present invention may have substantially the same features as the side effect system according to the present invention, although they are of different categories. Thus, the above-described features associated with the side effects system can be easily modified and applied to the side effects method.

While the invention has been shown and described with reference to certain preferred embodiments thereof, 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 invention as defined by the appended claims. Therefore, the scope of the invention is defined not by the detailed description of the invention but by the appended claims, and all differences within the scope will be construed as being included in the present invention.
