Title: Method and system for providing 3d teeth alignment image display services, and computer-readable medium on which the method is recorded

Description:
BACKGROUND 
     1. Field 
     The present invention relates to a method and system for providing 3D teeth alignment image display services, and a computer-readable medium on which the method is recorded and, more particularly, to a method and system for providing 3D teeth alignment image display services to display virtual teeth alignment images as a 3D hologram image to an orthodontic patient, and a computer-readable medium on which the method is recorded. 
     2. Description of the Related Art 
     Orthodontic treatment may be classified into metal-brace treatment using metal braces, lingual treatment using lingual braces, and clear-aligner treatment using clear aligners. 
     In particular, clear-aligner treatment attracts people&#39;s attention compared to the other orthodontic treatment methods because a transparent clear aligner covering teeth like a mouth piece is invisible, detachable, and easily wearable. 
     The Internet consists of a huge number of computers and computer networks for globally interconnecting the computers using communication links. 
     The interconnected computers exchange information using a variety of services, e.g., e-mails, Gopher, and World Wide Web (WWW). The World Wide Web allows a server computer system (e.g., a web server or a website) to transmit graphical webpages of information to a remote client computer system. 
     The remote client computer system may display various webpages received from the server computer. 
     Due to rapid development of wireless communication networks including a mobile communication network such as a second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G), or long term evolution (LTE) network, a WIFI communication network, a Bluetooth communication network, a cellular communication network, a code division multiple access (CDMA) communication network, an Ethernet communication network, a WiMAX communication network, a local area network (LAN), a wide area network (WAN), a radio frequency (RF) communication network, an infrared communication network, an optical communication network, and a near field communication (NFC) network, a variety of systems are being developed using the wireless communication networks. 
     According to the conventional orthodontic treatment methods using orthodontic appliances such as clear aligners, since orthodontic patients are able to actually check their aligned teeth or face contours only after orthodontic treatment is finished and are not able to accurately know the same before orthodontic treatment is finished, reliability of orthodontic treatment may not be high. As such, many people may decide not to receive orthodontic treatment and thus may not have their teeth aligned. 
     In addition, orthodontic patients should imagine their aligned teeth or face contours using only 2D images which are not appropriate to express lifelike teeth or face contours of people, and the inappropriate 2D images increase dissatisfaction of the orthodontic patients and thus are unhelpful for business, advertisement, or promotion. 
     SUMMARY 
     The present invention provides a method and system for providing 3D teeth alignment image display services by inputting a target teeth information on an orthodontic patient from an orthodontist to a server computer, transforming the target teeth information into a virtually aligned teeth information, transforming the virtually aligned teeth information into three-view or four-view image information, transmitting the three-view or four-view image information to the orthodontist or an orthodontic appliance manufacturer, and displaying a 3D teeth alignment image using a 3D holographic device of the orthodontist, to increase reliability of orthodontic treatment, to increase confidence and satisfaction of the orthodontic patient in orthodontic treatment, to achieve advantages in business, advertisement, or promotion, and to provide differentiated and high-value-added services, and a computer-readable medium having recorded the method thereon.

     Herein, the server computer  60  is programmed to receive a target teeth information on the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10  such that three or four images of a display  3  are respectively projected onto a pyramidal three-sided or four-sided projection plate  2  of a 3D holographic device  1  and thus the orthodontic patient checks a 3D hologram of his/her virtually aligned teeth, to transform a virtually aligned teeth information that is obtained based on the target teeth information, to a three-view or four-view image information outputtable by the display  3  such that the virtually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2 , and to transmit the three-view or four-view image information to the orthodontist terminal  20 , and may be a computer provided at a company, an agency, or a franchise capable of providing the 3D teeth alignment image display services through the network  50 . 
     The server computer  60  is not limited to a server computer and may be one of a variety of computers or computing devices capable of functioning as servers. 
     For example, the orthodontic patient terminal  10  may be a device of the orthodontic patient who desires to check his/her virtually aligned teeth or face contour images as a 3D hologram, using the system of the present invention. 
     Herein, the orthodontic patient terminal  10  is not limited to a smartphone and may be one of all information devices capable of transmitting target teeth information. For example, the orthodontic patient terminal  10  may be a personal computer, a mobile device, a personal digital assistant (PDA), a smart pad, a laptop computer, a smart camera, a smart camcorder, an electronic book, a smart scanner, or the like. 
     For example, the orthodontist terminal  20  may be a device of the orthodontist, e.g., a dentist, a dental nurse, or a dental professional, who desires to provide differentiated and high-value-added services or to achieve advantages in business, advertisement, or promotion by providing aligned teeth images as a virtual 3D hologram image of the 3D holographic device  1  to the orthodontic patient, using the system of the present invention. 
     Herein, the orthodontist terminal  20  is not limited to a smartphone and may be one of a variety of cameras, 3D cameras, scanners, 3D scanners, etc. capable of inputting the target teeth information of the orthodontic patient, and all information devices capable of receiving or displaying image information used for a 3D hologram, e.g., the 3D holographic device  1  of  FIG. 1 . For example, the orthodontist terminal  20  may be a camera, a 3D camera, a scanner, a 3D scanner, a personal computer, a mobile device, a PDA, a smart pad, a laptop computer, a smart camera, a smart camcorder, an electronic book, a smart scanner, the 3D holographic device  1 , or the like. 
     For example, the orthodontic appliance manufacturer device  30  may be a computer or a smartphone provided at a company, an agency, or a franchise which desires to manufacture a variety of orthodontic appliances, e.g., a clear aligner set and added or modified clear aligners to be provided to the orthodontic patient, using the system of the present invention. 
     Herein, the orthodontic appliance manufacturer device  30  is not limited to a smartphone and may be one of all information devices capable of receiving information about manufacturing of the orthodontic appliances. For example, the orthodontic appliance manufacturer device  30  may be a personal computer, a mobile device, a PDA, a smart pad, a laptop computer, a smart camera, a smart camcorder, an electronic book, a smart scanner, or the like. 
     For example, the operator device  100  is a device of a person, a company, an agency, or a franchise for managing and operating the server computer  60 , is not limited to a computer or a smartphone, and may be an information device, a PDA, a smartphone, a smart pad, a camera, a camcorder, a laptop computer, an electronic book, a personal computer, or another server computer capable of receiving various types of text information, number information, or image information, and of selecting various commands. 
     Although the orthodontic appliance manufacturer device  30  and the operator device  100  are separately managed in  FIG. 1 , the present invention is not limited thereto. For example, the above-described operator device  100  may also serve as the orthodontic appliance manufacturer device  30 . That is, the operator may also be the orthodontic appliance manufacturer. In addition, the operator may also be the orthodontist. 
     The orthodontic patient terminal  10 , the orthodontist terminal  20 , the orthodontic appliance manufacturer device  30 , the operator device  100 , and the server computer  60  of  FIG. 1  are interconnected through the network  50  using various applications, hybrid applications, or programs installed thereon. The devices  10 ,  20 ,  30 , and  40  interconnected through the network  50  may use a conventional mobile communication network such as a second generation (2G), third generation (3G), or fourth generation (4G) network, a WIFI communication network, a Bluetooth communication network, a cellular communication network, a code division multiple access (CDMA) communication network, a long term evolution (LTE) communication network, an Ethernet communication network, a WiMAX communication network, a local area network (LAN), a wide area network (WAN), a radio frequency (RF) communication network, an infrared communication network, an optical communication network, or a near field communication (NFC) network, and may have an Internet browser (e.g., Netscape or Internet Explorer) capable of displaying websites in the form of HTML, XML, or HTMLS, an internal, external, or short-distance/long-distance wired/wireless network access protocol device, or the like. 
     As illustrated in  FIG. 1 , the server computer  60  includes a program controller PG for controlling programs, and a database DB for storing various types of information. 
     Particularly, as illustrated in  FIG. 1 , the program controller PG may include a main program  61  for managing all the other programs, a membership program  62  for receiving a membership information from the orthodontic patient terminal  10 , the orthodontist terminal  20 , or the orthodontic appliance manufacturer device  30  and storing the membership information, a log-in program  63  for receiving a log-in information from the orthodontic patient terminal  10 , the orthodontist terminal  20 , or the orthodontic appliance manufacturer device  30 , a target teeth information input program  64  for receiving the target teeth information on the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10  such that the three or four images of the display  3  are respectively projected onto the pyramidal three-sided or four-sided projection plate  2  and thus the orthodontic patient checks the 3D hologram of his/her virtually aligned teeth, a three-view or four-view image information transformation program  65  for transforming the virtually aligned teeth information that is obtained based on the target teeth information, to the three-view or four-view image information outputtable by the display  3  such that the virtually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2 , a three-view or four-view image information transmission program  66  for transmitting the three-view or four-view image information to the orthodontist terminal  20 , a virtual alignment program  67  for virtually aligning the target teeth information into the virtually aligned teeth information, a comparison program  68  for receiving a completely aligned teeth information on completely aligned teeth of the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10 , transforming an actually aligned teeth information to a three-view or four-view image information outputtable by the display  3  such that the actually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2  to be compared with the virtually aligned teeth information, and transmitting the three-view or four-view image information to the orthodontist terminal  20 , and other programs  69  for performing other functions, e.g., home page management, promotion, advertisement, data processing, cost management, and application installation. 
     Herein, the main program  61  manages all the other programs. The main program  61  may be implemented in the form of an on-line home page or a main page of an application, and may be a program for controlling all the other programs by receiving various command signals from the orthodontic patient terminal  10 , the orthodontist terminal  20 , the orthodontic appliance manufacturer device  30 , and the operator device  100 . 
     The membership program  62  may be a program for registering the orthodontic patient, the orthodontist, and the orthodontic appliance manufacturer as members. The membership program  62  may provide standard terms or terms for collecting and using personal information and may get an agreement thereof to receive the membership information from the orthodontic patient terminal  10 , the orthodontist terminal  20 , or the orthodontic appliance manufacturer device  30  and to store the membership information. For example, the membership information may include at least one of a real name, an Internet personal identification number (i-PIN), an identifier (ID), a password, an e-mail address, a mobile phone number, an address, personal information, a department name, a position name, an employee identification number, a resident registration number, and a unique number. 
     The log-in program  63  may be a program for receiving the log-in information, e.g., an ID or a password, required when the orthodontic patient, the orthodontist, or the orthodontic appliance manufacturer logs in the server computer  60 , from the orthodontic patient terminal  10 , the orthodontist terminal  20 , or the orthodontic appliance manufacturer device  30 . 
     The target teeth information input program  64  may be a program for receiving the target teeth information indicating a current state of teeth or face contours of the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10 . For example, the target teeth information may include image or value information obtained from the orthodontic patient using a camera, a 3D camera, or a 3D scanner provided at a clinic of the orthodontist. 
     Accordingly, the orthodontist may transmit the target teeth information of the orthodontic patient, which is obtained by a camera or a scanner, through the network  50  to the server computer  60  using the target teeth information input program  64 . 
     However, the person who inputs the target teeth information is not limited to the orthodontist, and the orthodontic patient may obtain the target teeth information by photographing or scanning himself or herself using the orthodontic patient terminal  10  and transmit the same through the network  50  to the server computer  60 . 
     Alternatively, the person who inputs the target teeth information may be the orthodontic appliance manufacturer. In this case, the orthodontic appliance manufacturer may obtain the target teeth information by photographing or scanning the orthodontic patient using a camera, a 3D camera, or a 3D scanner provided at an office and transmit the same through the network  50  to the server computer  60 . 
     Herein, for example, the target teeth information may include at least one of teeth photo information obtained by photographing teeth or dental impressions of the orthodontic patient, 3D-scanned teeth information obtained by 3D-scanning the teeth or the dental impressions of the orthodontic patient, face photo information obtained by photographing a face of the orthodontic patient, 3D-scanned face information obtained by 3D-scanning the face of orthodontic patient, current mouth shape information of the orthodontic patient, current voice information of the orthodontic patient, current facial expression information of the orthodontic patient, and combinations thereof. 
     The three-view or four-view image information transformation program  65  may be a program for transforming the virtually aligned teeth information virtually aligned based on the target teeth information, into the three-view or four-view image information outputtable by the display  3  in such a manner that the virtually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2 . In detail, as illustrated in  FIGS. 7 and 8  to be described below, the three-view or four-view image information transformation program  65  may be a program for providing different-view images of an object in such a manner that the display  3  simultaneously projects and displays the images as a 3D hologram in a 3D space. 
     Herein, for example, as illustrated in  FIGS. 7 and 8 , the three-view or four-view image information may be information that can be displayed by the display  3 , and may include at least one of a front view image information, a left side view image information, a right side view image information, and a rear view image information, and combinations thereof, indicating virtually aligned teeth or face contours of the orthodontic patient. The front view image information, the left side view image information, the right side view image information, and the rear view image information may be information on images which are radially provided in three or four equiangular directions about a point that corresponds to an apex of the three-sided or four-sided projection plate  2  and thus are respectively projectable onto sides of the three-sided or four-sided projection plate  2 . 
     However, the three-view or four-view image information may not always include the rear view image information, and the rear view image information may be omitted. 
     Herein, the positions, sizes, angles, distances, etc. of the image information included in the three-view or four-view image information may vary depending on the shape, size, and projection angle of the three-sided or four-sided projection plate  2 , a viewer location, etc., and may be optimized to maximize the 3D hologram effect. 
     Accordingly, since the three-view or four-view image information is easily obtainable using the 3D teeth alignment image display service providing system of the present invention without using additional computing equipment and a technical professional, the orthodontist may provide high-value services to meet customer satisfaction and may achieve great advantages in business, promotion, or advertisement. 
     The three-view or four-view image information transmission program  66  may be a program for transmitting the three-view or four-view image information to the orthodontist terminal  20 . The orthodontist terminal  20  may be one of a large variety of electronic devices. 
     That is, when the orthodontist terminal  20  is an information device such as a smartphone or a personal computer, the orthodontist may receive the three-view or four-view image information and output the same to the display  3  of the 3D holographic device  1  to display a 3D hologram image. 
     Alternatively, the orthodontist terminal  20  may also serve as the 3D holographic device  1 . In this case, the orthodontist may output the three-view or four-view image information to the display  3  immediately after receiving the same, to display a 3D hologram image. 
     The virtual alignment program  67  may be a program for virtually aligning the target teeth information into the virtually aligned teeth information. The virtually aligned teeth information may be automatically generated using an automated internal algorithm. If necessary, partial correction may be manually performed. 
       FIG. 2  is a side view of a virtual face for describing a process for generating the virtually aligned teeth information by the virtual alignment program  67  of the 3D teeth alignment image display service providing system of  FIG. 1 , and  FIG. 3  is a bottom view of virtual teeth for describing the process for generating the virtually aligned teeth information by the virtual alignment program  67  of the 3D teeth alignment image display service providing system of  FIG. 1 . 
     Initially, as illustrated in  FIG. 2 , the virtual alignment program  67  may be a program for virtually moving anterior teeth in the target teeth information in such a manner that a front line FL of the anterior teeth meets an aesthetic guide line KL corresponding to a virtual line for connecting a first skin point n′ located in front of a nasion n from which nasal bones start based on a profile skull line of a person, to a second skin point p′ located in front of a pogonion p. 
     Then, as illustrated in  FIG. 3 , the virtual alignment program  67  may move the other teeth onto virtual and ideal correction arcs CA 1  and CA 2  based on the moved anterior teeth, thereby virtually aligning the target teeth information into the virtually aligned teeth information. 
     Subsequently, using the virtual teeth information, the virtual alignment program  67  may also generate virtual face contour information, virtual mouth shape information, virtual voice information, or facial expression information implementable using the aligned teeth by the orthodontic patient. 
     That is, the virtually aligned teeth information generated due to the above-described virtual process may include at least one of virtually corrected teeth information of the orthodontic patient, virtually corrected face contour information of the orthodontic patient, virtually corrected mouth shape information of the orthodontic patient, virtually corrected voice information of the orthodontic patient, virtually corrected facial expression information of the orthodontic patient, and combinations thereof. 
     The comparison program  68  may be a program for receiving a completely aligned teeth information on the completely aligned teeth of the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10 , transforming an actually aligned teeth information to the three-view or four-view image information outputtable by the display  3  such that the actually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2  to be compared with the virtually aligned teeth information, and transmitting the three-view or four-view image information to the orthodontist terminal  20 . For example, the orthodontist may overlap and display the virtually aligned teeth information and the actually aligned teeth information of the orthodontic patient using the 3D holographic device  1 , numerically display virtually and actually aligned positions, or display a rate of matches therebetween in percentage, and thus confidence and satisfaction of the orthodontic patient may be further increased. Furthermore, if the above data is provided to other orthodontic patients, an effect of advertisement or promotion may be achieved. 
     Herein, the above-described programs may be executive programs downloaded or installed in the orthodontic patient terminal  10 , the orthodontist terminal  20 , the orthodontic appliance manufacturer device  30 , or the operator device  100 , and may operate in association with user applications. 
     However, the above-described programs are not limited to executive programs or association with smartphone applications, and may operate in association with various types of devices. 
     Accordingly, since the orthodontist, e.g., a dentist, may accurately and realistically display various types of virtual teeth alignment information predicted after orthodontic treatment, to a patient, i.e., the orthodontic patient, as a 3D hologram using the 3D holographic device  1 , reliability of the orthodontic patient in orthodontic treatment may be increased and thus confidence and satisfaction in orthodontic treatment may also be increased. Therefore, advantages in business, advertisement, or promotion may be achieved and thus differentiated and high-value-added services may be provided. Furthermore, after orthodontic treatment, other orthodontic patients may predict accuracy of orthodontic treatment by comparing actual teeth information to predicted virtual teeth information. 
     As illustrated in  FIG. 1 , the database DB may include a membership information database  81  for storing the membership information, a log-in information database  82  for storing the log-in information, a target teeth information database  83  for storing the target teeth information, a three-view or four-view image information database  84  for storing the three-view or four-view image information, a virtually aligned teeth information database  85  for storing the virtually aligned teeth information, an actually aligned teeth information database  86  for storing the actually aligned teeth information, and other information databases  87  for storing other information. 
     Accordingly, the server computer  60  may provide 3D teeth alignment image display services for receiving the target teeth information of the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10  using the target teeth information input program  64 , virtually aligning the target teeth information into the virtually aligned teeth information using the virtual alignment program  67 , transforming the virtually aligned teeth information that is obtained based on the target teeth information, into the three-view or four-view image information outputtable by the display  3  such that the virtually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2 , using the three-view or four-view image information transformation program  65 , transmitting the three-view or four-view image information to the orthodontist terminal  20  using the three-view or four-view image information transmission program  66 , and receiving a completely aligned teeth information on the completely aligned teeth of the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10 , transforming an actually aligned teeth information into the three-view or four-view image information outputtable by the display  3  such that the actually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2  to be compared with the virtually aligned teeth information, and transmitting the actually aligned teeth information to the orthodontist terminal  20 , using the comparison program  68 . 
       FIG. 4  is a conceptual view showing the relationship among the operator for providing 3D teeth alignment image display services of the present invention, the orthodontic patient, the orthodontist, and the orthodontic appliance manufacturer. 
     Therefore, as illustrated in  FIG. 4 , the operator for operating the server computer  60  may receive fees and charges for the 3D teeth alignment image display services from the orthodontic patient, the orthodontist, and the orthodontic appliance manufacturer. The orthodontic patient, the orthodontist, and the orthodontic appliance manufacturer may receive the high-quality 3D teeth alignment image display services, teeth alignment information, orthodontic appliance information, or the like. As such, confidence and satisfaction may be provided to orthodontic patients, advantages in business, advertisement, or promotion may be achieved, and thus a business model which is advantageous and useful to all may be provided. 
       FIG. 5  is a flowchart of a method of providing 3D teeth alignment image display services, according to some embodiments of the present invention. 
     As illustrated in  FIGS. 1 to 5 , the 3D teeth alignment image display service providing method according to some embodiments of the present invention may sequentially include configuring the server computer  60  capable of providing the 3D teeth alignment image display services, (a) receiving a target teeth information on the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10  using the target teeth information input program  64 , (b) transforming a virtually aligned teeth information that is obtained based on the target teeth information, to a three-view or four-view image information outputtable by the display  3  such that the virtually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2 , using the three-view or four-view image information transformation program  65 , and (c) transmitting the three-view or four-view image information to the orthodontist terminal  20  using the three-view or four-view image information transmission program  66 . 
       FIG. 6  is a flowchart of a method of providing 3D teeth alignment image display services, according to other embodiments of the present invention. 
     As illustrated in  FIGS. 1 to 6 , the 3D teeth alignment image display service providing method according to other embodiments of the present invention may sequentially include configuring the server computer  60  capable of providing the 3D teeth alignment image display services, (a) receiving a target teeth information on the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10  using the target teeth information input program  64 , (d) virtually aligning the target teeth information into virtually aligned teeth information using the virtual alignment program  67 , (b) transforming the virtually aligned teeth information virtually aligned based on the target teeth information, to a three-view or four-view image information outputtable by the display  3  such that the virtually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2 , using the three-view or four-view image information transformation program  65 , (c) transmitting the three-view or four-view image information to the orthodontist terminal  20  using the three-view or four-view image information transmission program  66 , and (e) receiving a completely aligned teeth information on completely aligned teeth of the orthodontic patient from the orthodontist terminal  20  or the orthodontic patient terminal  10 , transforming an actually aligned teeth information to a three-view or four-view image information outputtable by the display  3  such that the actually aligned teeth information is projectable onto the three-sided or four-sided projection plate  2  to be compared with the virtually aligned teeth information, and transmitting the three-view or four-view image information to the orthodontist terminal  20 , using the comparison program  68 . 
     Accordingly, since the orthodontist may provide a 3D teeth alignment image to the orthodontic patient using the 3D holographic device  1 , reliability of the orthodontic patient in orthodontic treatment may be increased, confidence and satisfaction in orthodontic treatment may also be increased, and thus the orthodontic patient may easily decide to receive orthodontic treatment. Therefore, advantages in business, advertisement, or promotion may be achieved and thus differentiated and high-value-added services may be provided. Furthermore, after orthodontic treatment, other orthodontic patients may predict accuracy of orthodontic treatment by comparing actual teeth information to predicted virtual teeth information. Therefore, more advantages in business, advertisement, or promotion may be achieved. 
     As described above, according to some embodiments of the present invention, since an orthodontist may provide a 3D teeth alignment image using a 3D holographic device, reliability of an orthodontic patient in orthodontic treatment may be increased and thus confidence and satisfaction in orthodontic treatment may also be increased. Therefore, advantages in business, advertisement, or promotion may be achieved and thus differentiated and high-value-added services may be provided. Furthermore, after orthodontic treatment, other orthodontic patients may predict accuracy of orthodontic treatment by comparing actual teeth information to predicted virtual teeth information. However, the scope of the present invention are not limited to the above-described effects. 
     The present invention can also be embodied as computer-readable code on a computer-readable medium. 
     The computer-readable medium is any data storage device that can store data which can be thereafter read by a computer system. 
     Examples of the computer-readable medium include not only the above-described server computer  60  but also read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, magneto-optical disks, optical data storage devices, flash memory, and carrier waves (e.g., transmission through the Internet). 
     The computer-readable medium can also be distributed over network coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. 
     While the present invention has been particularly shown and described with reference to embodiments thereof, it will be understood by one of ordinary skill 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 as defined by the following claims.
