[ o o o i ] This application claims the benefit under 35 USC 19(e) of U.S. Provisional Application No. 62/581,207, filed on November 3, 2017, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

[ 0002 ] Enterprises, such as private and public companies, municipal, state and federal governmental agencies, and other entities, will often maintain a number of disparate systems to support their operations, track their business relationships, and maintain security. Enterprise Resource Planning (ERP) systems are computer systems that allow enterprises to manage operations. Employee Resource Management (ERM) systems are typically different computer systems that allow the enterprises to track, schedule, and pay their employees. Access control systems are principally concerned with physical security and the selective access to, restriction of access to, and/or notification of access to the enterpri ses' buildings and/or secured parts of those buildings. Information technology (IT) security systems are principally concerned with control and restricting access to computer resources, often including access to any ERP or ERM systems, and possibly other systems such as file servers, etc. In addition, other security systems are often employed by the enterprises to round-out their security needs. A common example is a surveillance system, which may be integrated with any access control sy stem to varying degrees.

[ 0003 ] The ERM systems store and manage many different types of information associated with employees. The ERM system might execute on a single computer system or server, or across multiple computer sy stems and servers, or be implemented in a cloud- based computer system. The different types of employee information often controlled and managed by the ERM systems include biographic, including demographic, information, payroll and salary information, job performance and attendance information, benefits information, and training and compliance information, to list some common examples.

[ 0004 ] Modern ERM systems typically encompass the functionality of multiple legacy systems that had separately managed and stored the different types of information associated with the employees. These legacy systems might have had separate payroll systems for the payroll and salary information, human resources systems for the biographic, job performance and attendance information, benefits systems for the benefits information, and learning systems for the training and compliance information, in examples. At the same time, the ERM system can simply be a collection of local or remote databases that store the different types of information associated with each employee, r o o o 5 j ERP systems generally track business resources such as cash, raw materials, and production capacity. The ERP systems can track business commitments such as orders, purchase orders, and possibly might overlap with ERM systems. As such, these ERP systems are computer systems that often include computer databases and database management systems for the databases, along with different user interfaces. The different user interfaces allow the operators to obtain information from the systems and submit information to them. The ERP systems typically further include various computer systems connected with manufacturing and the control and management of other operations of the enterprises, r 0006 j IT security systems can take many forms. They will often include asset management database computer systems that allow the enterprises to track their computers, the status of the computers, individuals to whom the computers are assigned, along with other systems such as servers, cloud server systems, and networking devices, to list some examples. The IT security systems will almost always include one or more authentication server systems. These computers provide network services that computer systems and applications that execute on those computer systems use to authenticate the credentials, usually account names and passwords, of their users. For example, when a client computer successfully submits a valid set of credentials that were entered by a user trying to log onto the computer, the client computer receives a cryptographic ticket that it can subsequently use to access various other systems such as the enterprise's ERP systems, ERM systems and other computers systems such as even mundane file servers.

[ 0007 ] The access control systems typically include access control readers. These readers are often installed at access points of the buildings to control access to restricted areas, such as buildings or areas of the buildings. Examples of access points include front and interior doors of a building, elevators, hallways connecting two areas of a building, to list a few examples. The access control readers authenticate identities of (or authorize) individuals and then permit those authenticated individuals to access the restricted areas through the access points. Typically, individuals interact with the access control readers by swiping keycards or bringing contactless smart cards within range (approximately 2-3 inches or 5 centimeters) of a reader. The access control readers read user information of the keycards, such as credentials of the individuals, and then the access control systems determine if the individuals are authorized to access the restricted areas. If the individuals are authorized to enter the restricted areas, then the access control readers allow access to the restricted areas by unlocking locked doors, signaling that doors should be unlocked, or generating alarms upon unauthorized entry, for example.

: 0008 ] More recently, frictioniess access control systems are being proposed and designed. These systems typically rely on individuals carrying beacon devices that can broadcast credentials, such as dedicated fob devices or personal mobile computing devices such as tablet or smart phone computing devices. These systems are "frictioniess" in that the individual may not have made any overt gesture indicating a desire to access the restricted area, e.g., the individuals did not swipe a key card. The access control systems will then monitor and track the individuals as they move through the buildings and automatically open access points such as doors when approached, assuming that the individuals are authorized to pass through those access points.

[ 0009 ] Enterprise surveillance systems are used to help protect people, property, and reduce crime. These systems are used to monitor buildings, lobbies, entries/exits, and secure areas within the buildings of the enterprises, to list a few examples. The surveillance systems record illegal activity such as theft or trespassing, in examples. At the same time, these surveillance systems can also have business uses. They can track employee locations across different rooms within buildings and among the different buildings of the enterprises,

[ 0010 ] In these surveillance systems, surveillance cameras capture image data of scenes. The image data is typically represented as two-dimensional arrays of pixels. The cameras then include the image data within streams, and users of the system such as security personnel view the streams on display devices such as video monitors. The image data is also typically stored to a video management system (VMS) for later access and analysis.

[ o o 11 ] Increasingly, it is being proposed to make these VMSs smarter. For example, VMSs with image analytics systems are becoming more prevalent. These analytics systems allow the VMSs to interpret the captured image data and possibly send alerts when detecting trespassing or other problems. One common type of image analytics is facial recognition. In such instances, modules of the VMS will identify faces within the image data and compare those faces to databases to try to identify the different individuals captured in the image data,

SUMMARY OF THE INVENTION

[ 0012 ] A proposed enterprise security system obtains information from disparate repositories and combines the information with tracking information to validate movement of individuals within the enterprise and also uses the information to validate log-on events on computer systems. In one application, the enterprise security system uses the combined information to determine whether the individuals are located in and/or moving to a correct/authorized location for those individuals. For example, based upon a desk location, it will be possible to monitor the iocation of an individual within a building and determine that they are in and/or are moving to the correct location within the building.

[ 0013 ] Additional functions are possible. The system can use biographic and physical information such as age, gender, facial hair, and whether or not the person is wearing glasses, in examples, to determine that obtained facial recognition information matches that of an employee record maintained by the ERM system. The system can combine facial recognition with information technology (IT) systems monitoring to confirm that a person whose face has been recognized uses the correct login identifier to log into a computer system within the building(s) of the enterprise.

[ 0014 ] In general, according to one aspect, the invention features an enterprise security system. The system includes one more tracking systems, an IT system and a security- integration system. The one or more tracking systems track movement of the individuals throughout the enterprise. The IT system provides access to computer resources within the enterprise. The security integration system can then generate commands to block access to the computer resources based on the tracked movement of the individuals within the enterprise. r 0015 j In this way, the system might augment the validation provided by a traditional authentication server by ensuring that log-on attempts are consistent with the individuals actually present in a conference room, for example. [ 0016 ] In embodiments, the tracking systems include a surveillance system including surveillance cameras and a facial recognition module for performing facial recognition of individuals in the image data from the surveillance cameras. The tracking systems can also, or alternatively, include access control systems that control access of individuals through access points within the enterprise.

[ 0017 ] Typically, the security integration system determines authorized computer systems for individuals and instructs the IT system to block access to the computer systems when authorized users of the computer systems are not present. The security integration system can also access an asset management database to determine locations of the computer systems within the enterprise.

[ 0018 ] In general, according to another aspect, the invention features an enterprise security system. The enterprise security system includes one or more tracking systems for tracking movement of individuals throughout an enterprise, an employee resource management system including an employee database, and a security integration system. The employee database stores location of desks of the employees. The security integration system receives a metadata stream of the tracked movement of the employees and determines whether the employees are moving to and/or from the respective desks of the employees by reference to the information from the employee database. r o o 19 j In general , according to yet another aspect, the invention features an enterprise security method. The method includes tracking movement of individuals throughout an enterprise, providing access to computer resources within the enterprise using an authentication server, and blocking access to the computer resources based on the tracked movement of the individuals within the enterprise. r o 02 o j In one example, tracking movement includes controlling and reporting access of individuals through access points within the enterprise. Tracking movement can further or alternatively include capturing images of the individuals and performing facial recognition of the individuals.

[ 0021 ] In general, according to still another aspect, the invention features another enterprise security method. This method includes tracking movement of individuals throughout an enterprise, an employee resource management system including an employee database indicating location of desks of the employees, and receiving a metadata stream of the tracked movement of the employees and determining whether the employees are moving to and/or from the respective desks of the employees.

[ 0031 ] Fig. 1 shows an exemplary enterprise including an enterprise security system 100, which has been constructed according to the principles of the present invention.

[ 0032 ] The figure shows client computer systems 122 at a building 50 of the enterprise. Some of these client computer systems might be public terminals in conference rooms that might be used by different individuals over the course of the day. In other examples, the client computer systems 122 are dedicated computer systems assigned to a specific employees of the enterprise or shared computers systems such as servers or server systems,

[ 0033 ] Also shown are other computer systems that are associated with the operations of the enterprise, such an enterprise information technology (IT) system 20, a surveillance system, an ERM system 138, a file server 42, an access control system 128, and an ERP system 44. Finally, a security integration system (SIS) 80 provides some of the important functions of the present invention. A local area or enterprise network 210 provides network connectivity. [ 0034 ] In more detail, the cameras 103 of the surveillance system capture image data 99 of the rooms 1 13 throughout the enterprise's building and thus images of individuals 60 in each room 1 13. Cameras 103-1 and 103-2 are respectively installed in rooms 1 13-1 and 1 13-2. r 0035 j The surveillance system's VMS 1 0 stores the image data 99 from the cameras 103 and includes a camera locations table 21 and a facial recognition module 107. The camera locations table 21 typically has a record for each of the surveillance cameras 103. The record contains such information as the room in which the camera is installed. It may also include information concerning the type of camera and possibly even the field of view of the camera with respect to a map or floor layout of the building 50. The facial recognition module 107 determines facial recognition information of the individuals captured in the image data and monitors movement and/or activity of individuals 60 within the rooms 1 13. r 0036 j The IT system 20 includes an authentication server 22. The authentication server 22 allows the individuals 60 to log onto the computer systems 122, such as client computer systems, and then typically access other resources such as the file server 42 and/or the ERP system 44 and/or ERM system 138. For this purpose, the authentication server 22 has a user database 39 that stores user records 149 for the individuals 60. The individuals 60 are typically employees of the enterprise. Each user record 149 includes information that identifies each individual and the computer systems 122 each is authorized to access, in examples. In more detail, the user record 149 for each individual 60 typically includes a user ID 72, a login ID 144, user credentials including passwords 172, and a list of authorized computer systems 179.

[ 0037 ] Another common feature of IT systems is an asset management database 30. The asset management database 30 includes a computer locations table 96. As its name implies, the table 96 maintains locations (e.g. room numbers) for each of the computer systems 122. Often, these asset management databases 30 will include additional information such as specific details concerning the computer systems 122, such as production year operating system, applications installed on the computer systems and possibly other license information.

[ 0038 ] The ERM system 138 is preferably as described hereinabove. As such, it has an employee database 139 that stores employee records 123 of employees 60. The employee records 123 include information for identifying each employee and locations of desks 5 within the building 50 for the employees. In more detail, each employee record 123 typically includes a name 24, an employee number 32, a badge number 34, a badge photo 36, user biographic and physical information 141, an authorization level 151, and one or more desk locations 161. The desk locations 161 list the locations of desks that each employee is authorized to be present at or is otherwise expected to be near during work hours. In addition, the ERM system 138 may also include other information such as databases that store the same information for contractors and visitors to the enterprise.

[ 0039 ] The user biographic and physical information 141 includes other information for possibly identifying each individual 60. This information might include the following: a birthplace, home address, age, race, hair color/length, and whether the individual typically wears glasses, in examples.

[ 0040 ] The access control system 128 controls physical access through access points 10 of the building 50. In the illustrated example, the access points are doors, but may also include hallways or elevators or floors within the buildings of the enterprise. Typically, the access control system 128 further includes card readers for reading employee badges and/or frictionless readers that might validate employees based on credentials provided by a mobile computing device such as a smart phone operated by the employees. In this way, the access control system is able to monitor movement of individuals through access points.

[ 0041 ] In one embodiment, the enterprise security system includes one or more tracking systems (such as the surveillance system and/or the access control system). These one or more tracking systems track movement of the individuals 60 throughout the enterprise and provide this information as meta data streams. The IT system 20 provides access to computer resources within the enterprise and provides its own meta data stream of log-on events,

[ 0042 ] The SIS 80 functions to integrate the operation of the tracking system(s) and the IT system. As such, the SIS 80 can be a separate computer system or could be a process or module that executes on the IT system computers, e.g., authentication server, or on a computer associated with the tracking systems, or even a separate computer system or a computer system integrated with the ERP or ERM computer systems. In any case, the SIS instructs the IT system 20 to block access to the computer systems 122 when authorized users of the computer systems 122 are not present.

[ 0043 ] In the illustrated example, the computer systems 122 are located in the rooms 1 13. Room 1 1 1-1 includes computer system 122-1. Room 1 13-2 includes computer system 122-2 upon a desk 45. The locations and types of there computers are stored in the computer locations table 96 of the asset management database 30. Multiple individuals 60 are located within and/or are moving about the rooms 1 13, and are attempting to access computer resources from within the rooms 1 13. Individual 60-1 is located in rooml 1 13-1 and individual 60-2 is located in room2 1 13-2. Individual 60-2 is also located near the desk 45 and is attempting to access/log onto a user account via the computer system 122.

[ 0044 ] In general, the individuals 60 might be employees. As such, when the individuals are originally hired as employees, a guard or security operator or human resources representative would create the employee record 123 for each employee in the employee database 139. The security operator also takes a picture of the employee's face to use as the badge photo 36, and additionally uses the facial recognition module 107 of the VMS 1 10 to create stored facial recognition information for each of the employees.

[ 0045 ] The facial recognition information can be of different types. In one example, the information is a biometric identifier such as a facial signature of the individual. In another example, the information i s simply a still image of the person's face extracted from the image data, also known as a facial patch.

[ 0046 ] The facial signature for an individual is a unique value or set of values that represent the face of an individual/employee. The facial recognition module 107 uses one or various predetermined facial signature algorithms to create the facial signature, based upon various features of each person's face. These features include the eyes, nose, mouth, eyebrows, cheekbones, and chin of each face, and distances between each of these features, in examples.

[ 0047 ] The facial recognition module also maps each instance of facial recognition information (e.g. the facial signature or facial patch) for each employee to a user credential or other identifier (OD). In thi s way, the OD associated with each instance of stored facial recognition information can be used to identify the individual for which the facial signature was obtained. [ 0048 ] The V S 1 10 then stores the facial recognition information and associated ID for identifying each employee. In one example, the VMS stores this information locally to the VMS 110. In another example, the VMS 110 might store this information to the employee record 123 for each employee. r 0049 j The enterprise security system 100 generally operates as follows. After the individuals 60 are registered as employees, one or more individuals arrive at access points 10 such as doors of the building 50, The individuals typically present keycards that include their user credentials to the card readers 70 of the access control system 128 at the doors. The cameras 103 also capture and send the image data 99 of the individuals to the VMS 110.

[ 0050 ] The VMS 110 then uses its facial recognition module 107 to determine whether the images of the individuals 60 in the image data 99 from the surveillance cameras match the stored facial recognition information for registered employees. If the individuals 60 are determined to be employees, the VMS 110 operates in conjunction with the SIS 80, the IT system 20, the ERM 138, and possibly the ERP system 44 to determine whether the individuals are: in the correct rooms within the building 50; attempting to access computer systems to which they are authorized; and traversing paths near desk locations to which they are assigned, in examples. r 0051 j Fig. 2A is a sequence diagram that illustrates one application of the enterprise security system 100.

[ 0052 ] The enterprise security system 100 protects against improper access of computer systems 122 within the rooms 113 of the building. After the identity of the individual 60 entering or within a room 1 13 has been determined via facial recognition, only IT user records 149 associated with that individual will be allowed to be accessed from computer systems located within that room 113. Thus, if an othenvise authorized user 60 enters the room 113 and tries to use another person's credentials, the individual 60 will be prohibited from doing so. In this way, only an individual 60 that is expected to be near a computing system 122 at a specific location can log onto that computer system 122, in one example.

[ 0053 ] In more detail, in step 202, one or more card readers 70 read key card credentials of individuals 60 presented at the card readers. The card readers 70 send the credentials to the ACS 128 i step 204. [ 0054 ] According to step 206, the ACS 128 sends an indication as whether the individuals 60 are authorized. In one example, the indication is a door lock signal to unlock or otherwise disengage the door locks for the doors (or other access points) at which the card readers 70 are installed. The ACS 128 sends these indications to the door controller 112. Then, in step 208, the ACS 128 reports these credentials of the individuals 60 and the room 1 13 that each entered to the SIS 80 as an access control meta data stream.

[ 0055 ] At the same time, in step 210, the cameras 103-1 and 103-2 within the rooms 1 13-1 and 113-2 of the building 50 capture the image data 99 of scenes in the rooms 1 13. The cameras 103 send the image 99 to the VMS 110 for storage and subsequent analysis. r 0056 j In step 212, the facial recognition module 107 of the VMS 110 locates the individuals 60 in the image data 99. In step 214, the facial recognition module 107 then performs facial recognition of the individuals located in the image data 99 to identify the individuals 60. For this purpose, the facial recognition module 107 preferably uses the same facial recognition algorithms used when the security operators first registered the individuals as employees. In this way, the facial recognition module 107 can identify employees in the image data by reference to the badge photos 36 stored in the employee database 139 of the ERM system 138.

[ 0057 ] It can also be appreciated that the facial recognition module 107 can be included within and execute upon other components of the enterprise management system 100. In one example, the facial recognition module 107 might be integrated within the cameras 103 and execute upon a microcontroller of the cameras 103. In another example, the facial recognition module 107 might execute upon a microcontroller or central processing unit (CPU) of the ACS 128. r 0058 j In step 216, the VMS 1 10 provides a surveillance meta data stream of the identified individuals, using facial recognition, and the rooms 113 in which those individuals are located based on the location of the various cameras 103 that captured their image, along with a timestamp indicating the time of identificaiton. For this purpose, the VMS 1 10 executes a lookup of a camera identifier for each camera 103 in the camera locations table 21 to obtain the location (e.g. room number) of each camera 103, The VMS 110 then reports this information in the surveillance system meta data stream, including each identified individual and room and time, to the SIS 80. [ 0059 ] At the same time, in step 218, the security integration system 80 requests a list of authorized computer systems 179 for each of the employees from the authentication server 22 of the IT system 20. The authentication server 22 then returns the list of authorized computer systems 179 for each of the employees in step 220. r 0060 j The SIS 80 further determines the locations of the various computer systems 122 relative to the rooms 113 from the asset management database 30. This is indicated in step 222, For this purpose, the SIS 80 queries the computer locations table 96 of the asset management database 30. The asset management database 30 returns the computer locations relative to the rooms 1 13 back to the SIS 80 in step 224. r o o 61 j Then, based on the list of authorized computer system s for each individual and the computer systems in each room, the SIS 80 provides a white list of valid potential users, i.e., the valid users that are known to be in the same room as the computer systems, for each computer system 122. The SIS 80 provides the white list to the authentication server 22, in step 226.

[ 0062 ] The computer systems 122 might then receive user login requests from individuals 60 within the rooms, in step 228. For example, one of the individuals may try to logon to one of the client computers 122 by entering a username and password. The user login requests include at least user credentials (e.g. user ID, login ID) and a computer system name. The computer systems then send the user login requests including the user credentials and the requested computer system names to the authentication system 22 for further processing.

[ 0063 ] The authentication server 22, in step 230, compares the user credentials and the requested computer system names in the login requests to the white list of valid potential users for each computer system 122. Upon finding a matching entry in the white list for that individual 60, the authentication system 22 authenticates that individual on that computer system and might further send a message to the computer system 122 to allow access to the computer system 122 named in the user login request. Otherwise, the authentication server 22 denies/blocks access to the computer system named in the user login request when it has been determined that the user is not even present in the room, for example.

[ 0064 ] Fig. 2B is a sequence diagram that illustrates an alternate implementation for the enterprise security system 100. [ 0065 ] In Fig. 2B, steps 202 through 216 are substantially similar as steps 202 through 216 in Fig. 2A,

[ 0066 ] In step 280, the security integration system 80 requests a list of authorized computer systems for each of the employees from the authentication server 22 of the IT system 20. The authentication server 22 then returns the list of authorized computer systems 179 for each of the employees in step 282.

[ o o 6 ] The SIS 80 further determines the locations of the various computer systems 122 relative to the rooms 1 13 from the asset management database 30. This is indicated in step 284. For this purpose, the SIS 80 requests the computer locations table 96 of the asset management database 30. The asset management database 30 returns the computer locations relative to the rooms 113 back to the SIS 80 in step 286.

[ 0068 ] Then, based on the list of authorized computer systems for each individual and the computer systems in each room, the SIS 80 provides a black list of denied users for each computer system 122. In step 288, the SIS 80 provides the black list for each of the individuals 60 back to the authentication server 22.

[ 0069 ] The computer systems 122 then receive user login requests from individuals 60 within the rooms, in step 290. This is substantially similar to step 288 in Fig. 2A. The computer systems 122 then send the user login requests including the user credentials and the requested computer system names to the authentication system 22 for further processing.

[ 0070 ] The authentication system 22, in step 292, compares the user credentials and the requested computer system names in the login requests to the black list of denied users for each computer system 122. Upon finding a matching entry in the black list for that individual 60, the authentication server 22 blocks access to the computer system 122 named in the user login request.

[ 0071 ] In this way, the enterprise security system 100 also tracks movement of individuals throughout an enterprise, provides access to computer resources within the enterprise using an authentication server, and blocks access to the computer resources based on the tracked movement of the individuals within the enterprise.

[ 0072 ] Fig. 3 illustrates another method of operation for the enterprise security sy stem 100. [ 0073 ] As before, the VMS 110 provides a surveillance metadata stream to the SIS 80. The stream includes identified employees/individuals and location(s) in the building 50 where they were tracked along with a timestamp indicating the time of detection. The ACS 128 provides its access control meta data stream after employees interact with card readers, for example.

[ 0074 ] Now, the SIS 80 also accesses the ERM system 138 to determine the assigned desks for those employees and then confirms that the employees are on valid paths to or from their desks 45, in one example.

[ 0075 ] As before, the enterprise security system 100 includes one or more tracking systems for tracking movement of the individuals 60 throughout the enterprise. In this way, the SIS 80 receives a metadata stream of the tracked movements of the employees and determines whether the employees are moving to and/or from the respective desks of the employees by reference to information from the ERM 138.

[ 0076 ] In more detail, in step 250-1, camera 103-1 sends image data 99 captured of a scene within room 113-1 to the VMS 100. In a similar vein, camera 103-2 in step 250-2 sends image data 99 captured of a scene within room 113-2 to the VMS 110.

[ 0077 ] In step 252, the facial recognition module 107 of the VMS 1 10 locates the individuals 60 in the image data 99. The facial recognition module 107 then performs facial recognition of the individuals located in the image data 99 to identify the individuals 60 in step 254.

[ 0078 ] According to step 256, the VMS 110 sends the metadata stream of information for any employee/ individuals 60 identified, where the stream includes a building name, location (e.g. room 113) within the building 50, and a time stamp for each identified employee, in examples, to the SIS 80.

[ 0079 ] Also, as before, the ACS 128 also preferably provides its access control meta data stream to the SIS 80.

[ 0080 ] In step 258, the SIS 80 requests a list of assigned desk locations 161 for each identified employee. The desk locations 161 are included in the employee records 123 of the individuals, which the ERM system 138 maintains in its employee database 139. The ERM system 138 sends the list of assigned desk locations 161 for each identified employee back to the SIS 80 in step 260. In addition, the ERM system 138 sends the badge photo 36 for each identified employee to the SIS 80 in step 262.

[ 008 1 ] In step 264, the SIS 80 determines if each of the identified employees are traversing a path through the buiiding(s) 50 that is consistent with the list of assigned desk locations for each employee.

[ 0082 ] The SIS 80 also determines, in step 266, if surveillance images obtained of the rooms (at substantially the same times as the time stamps in the stream) include badge photos 36 that match the identified employee badge photos. A mismatch indicates that the individuals 60 in the rooms 1 13 may have stolen or forged their security badges. The SIS 80 can then send messages alerting security operators of this event so that the security operators can investigate further.

[ 0083 ] The method of operation for the enterprise security system 100 in Fig. 3 has additional benefits. The system might be used to monitor usage of desks 45 by the individuals 60 over time. This could then be provided as input to future real estate occupancy decisions by analyzing the space usage over a longer period. For example, if the occupancy is less than 80% of the available desk 45 space, an operator at the enterprise may wish to consider moving to a smaller building 50. Similarly, if the desk 45 space usage exceeds 90%, then, if the enterprise wishes to expand, it may need to consider moving to a larger building 50.

[ 0084 ] While this invention has been particularly shown and described with references to 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 scope of the invention encompassed by the appended claims.
