Description




BACKGROUND OF THE INVENTION




In current times, the issue of security has become a significant concern. We strive to keep secure our homes, schools, office buildings and airports. Many accounts have been reported of violent acts taking place such as shootings at schools, post offices, and places of business. In many of these instances, a person has been able to bring an unwanted object or gun into, or within close proximity to, a space area or building. Accordingly, a method for enhancing security around these areas is needed.




Many of the methods and systems presently used for providing security have significant shortcomings. Many of these systems depend on the vigilance of individual people to look for unwanted objects and interrogate persons who may be carrying unwanted objects. These systems are generally limited by the general vulnerability of security persons, the inability of a few security persons to maintain security over a large area to be secured, and basic human error.




SUMMARY OF THE INVENTION




The present invention is directed to a system and method for automatically maintaining the security of an area. In one embodiment of the invention, several space area network elements may be placed near, or in a shaped pattern around, an area to be kept safe, such as a school. The space area network elements are devices including sensors to sense the presence of an unwanted object such as a gun. The space area network elements may also include a wireless communication unit so that when the presence of an unwanted object or gun is sensed, a third party entity such as the police may be alerted. The space area network elements also include inter-element communication units that allow the space area network elements to share information within a space area network. Additionally, the space area network elements may include a positioning system unit that obtains data related to the position of the space area network or any of its elements. By way of the positioning system unit, position information may also be communicated to the third party entity. Accordingly, by use of the space area network, a safe area may be automatically monitored by space area elements. Information obtained regarding the unwanted object, including its position, may be shared among the space area network elements. This information may also be communicated to a third party entity.




In one embodiment of the invention, the unwanted object such as a gun may be sensed by an eddy current sensor located on the space area network elements. In addition, thermal or inductive systems, as well as X-ray and radiation leakage detection systems may be used in instead of, or in conjunction with, the eddy current sensors. The eddy current sensor may be designed to sense the presence of metal in order to detect unwanted objects such as guns. In another embodiment of the invention, the unwanted object, which may be a person, may include a passive receiver device or transponder. The space area network elements may then communicate a signal to detect the presence of any unwanted objects equipped with transponders. Further, the unwanted object may include an active communication device to communicate its presence, with this signal being received by a receiver unit on the space area network elements. Still further, the unwanted object and the space area network elements may both include positioning units and wireless communication units such that the unwanted object and the space area network elements may communicate their position information to a third party entity, such that the position data may be monitored and compared, and so that a space area may be kept safe.




By using the space area network elements, an area may be secured without dependence on the vigilance of individual people or security guards to look for unwanted objects or guns and interrogate persons who may be carrying unwanted objects. Also, by using the space area network elements and a space area network, an area may be automatically secured with less danger to security personnel, and with less susceptibility to human error.

may be, for example, a battery such as a nickel cadmium type, or a lithium ion type, or any other power supply unit as would be known by one skilled in the art. In an exemplary embodiment, power supply unit


20


may be relatively small so that it may be disposed on object area network element


10


with the total size of object area network element


10


such that it may be placed unobtrusively in clothing or on a person's body. In an exemplary embodiment, power supply unit


20


may be of a type wherein the power level remains at an operable level for a relatively long period of time such that replacement or recharging is only infrequently necessary.




Object area network element


10


may also have wireless communication unit

, which may facilitate communications via a cellular or other wireless network between an object area network element


10


and a base station, other object area network elements, or any other device capable of communicating via a wireless communications network. Wireless communications unit


14


, as discussed above with respect to other units of object area network element


10


, may be small enough to be disposed on an integrated circuit chip for easy and unobtrusive placement on clothing or parts of the human body, or other objects.




Object area network element


10


may also have sensor unit


16


. Sensor unit


16


may, in turn, have various sensing units used to gather information related to the monitored person as well as the environment surrounding such a person. Sensor unit


16


may include temperature sensing unit


22


. Temperature sensing unit


22


may be of a type capable of sensing the body temperature of the monitored person. Additionally, multiple temperature sensing units may be used so that the temperature of the surrounding air or environment may also be sensed. Temperature sensing unit


22


may be of any type known to those skilled in the art, its design being a matter of application-specific design choice. Sensor unit


16


may also have pressure sensing unit


24


which may sense the atmospheric pressure in the surrounding environment of the object area network element


10


and thus around the monitored person. Pressure sensing unit


24


may also facilitate the monitoring of a heart rate, or other vital functions of a monitored person. Pressure sensing unit


24


may be any type known to those skilled in the art and its specific design is a matter of application specific design choice. Sensor unit


16


may also have sound sensing unit


26


, which may be capable of sensing sounds from the monitored person as well as from the surrounding environment. Sound sensing unit


26


may be a miniature microphone or other such sensing unit, as may be determined by one skilled in the art as a matter of application specific design choice. Object area network element


10


may also have alerting unit


18


, which may be used by the monitored person in order to manually alert others of an impending dangerous situation or other such circumstances. In an exemplary embodiment, alerting unit


18


may be a miniature push button, microswitch, capacitive sensor, thermal sensor, or other such button or unit that may be easily triggered by a touch from the monitored person.




In an exemplary embodiment, object area network element


10


, and all components thereof, may be combined such that all or most elements are on a single integrated circuit chip, or at least in the same package or housing. This chip may be easily disposed on or within the monitored person's clothing, or easily and unobtrusively affixed to a unit of the monitored person's body, or even implanted beneath the skin of the monitored person.




Referring to

FIG. 2

, in an exemplary embodiment, multiple object area network elements


10


may be used with a monitored person or object


48


. An object area network system may have, for example, a first object area network element


50


, a second object area network element


52


and a third object area network element


54


. In an exemplary embodiment, first, second and third object area network elements


50


,


52


,


54


may be disposed over a relatively wide area of monitored person's


48


body. For example, object area network element


50


may be disposed on the upper unit of the monitored person's


48


body, such as near the wrist, arm, neck, head, shoulder, or chest. Second object area network element


52


may be disposed near the middle of monitored person's


48


body such as near the waist, or stomach. Third object area network element


54


may be disposed near the lower unit of the monitored person's


48


body such as near the knees, ankles, feet, calves, or other body parts on the lower unit of monitored person's


48


body.




Object area network elements


10


may be disposed directly on the monitored person's


48


body, or may be placed on or integrated into a monitored person's


48


clothing. For example, the object area network elements


10


may be integrated into a hat, shirt, belt, pants, socks, shoes, gloves, or other articles of clothing worn by the monitored person. An object area network element


10


may also be affixed to a monitored person's


48


skin at any of these locations, such as the arm, hand, wrist, chest, leg, feet, or other body parts. In an exemplary embodiment, object area network element


10


may be placed such that biometric information regarding the monitored person


48


, such as body temperature, heart rate, and sound made by the monitored person


48


may be sensed by object area network element


10


. Further, in an exemplary embodiment, information regarding the environment surrounding the object area network element


10


and monitored person


48


may also be sensed, such as the ambient temperature of the air, sound in the surrounding environment, or the atmospheric pressure in the surrounding environment. In an exemplary embodiment, object area network elements


10


may be small enough such that they may be unobtrusively disposed on the monitored person's


48


body or on or within the monitored person's


48


clothing, such that monitored person's movements and daily activities are not interfered with, and the object area network elements


10


are not easily discernible or viewable by other persons, such as a potential attacker. Further, since object area network elements


10


may be integrated into articles of clothing and also since multiple object area network elements


10


may be used within an object area network system on a monitored person


48


, it may be difficult and time consuming for a potential attacker to identify the location of, and remove or disable the multiple object area network elements


10


disposed near different regions of monitored person's


48


body. Also, since in an exemplary embodiment, the object area network elements


10


are disposed at different regions of monitored person's


48


body, a more reliable sampling of environmental and biometric information may be obtained than would be obtained from a sensor disposed at a single location of monitored person's


48


body. Also, if an object area network element


10


, such as, for example, first object area network element


50


, temporarily loses sensor contact with monitored person's


48


body, the other object area network elements


10


, such as, for example, second object area network element


52


and third object area network element


54


, may continue to receive sensor information regarding monitored person


48


. This ability to continue the monitoring of the monitored person


48


, while an object area network element temporarily loses sensor contact with the monitored person


48


, facilitates the minimizing of false alarms that may be triggered by a monitoring system that only uses a single monitoring element.




First object area network element


50


, second object area network element


52


, and third object area network element


54


wirelessly communicate with each other via local object area network


56


. By communicating via local object area network


56


, first object area network element


50


, second object area network element


52


, and third object area network element


54


may continuously check on the status and functionality of the other object area network elements


10


in object area network


56


in order to facilitate the working and operation of the system. In an exemplary embodiment, each object area network element


10


may have an inter-element communication unit


88


(see FIG.


1


). Object area network elements


10


may wirelessly communicate with each other via inter-element communication units


58


, forming local object area network


56


. Inter-element communication units


58


may be, for example, Radio Frequency (RF) devices, Infrared (IR) devices, or other short-range wireless communication devices such as those using the BLUETOOTH® communication technology and protocol. Additionally, object area network


56


may be formed via other wireless network communications devices as is known by those skilled in the art. Further, object area network elements


10


may communicate via local object area network


56


by use of wireless communications, whereby inter-element communication units


58


and wireless communications units


14


operate as a combined communication device. The use of local object area network


56


allows the object area network elements


10


to work together, using the inter-element communication units


58


, and to compare sensed information in order to average sampled data, such as body temperature, and also to minimize false alarms if one object area network element


10


is temporarily malfunctioning or is removed from misses sensory contact with the monitored person's


48


body or the ambient environment.




Each object area network element


10


, by use of its wireless communications unit


14


, may communicate via a wireless communications network, and, for example, a first wireless communications tower


88


to a base station


62


. It may be noted that this communication between the wireless communication unit


14


of an object area network element


10


and a base station


62


may be separate and distinct from the local network communications between the object area network elements


10


via inter-element communication units


58


.




By way of this wireless communication with a base station


62


, pertinent biometric data from the monitored person


48


, as well as data from the ambient environment may be automatically and continuously monitored via a wireless communications network at base station


62


. In this manner, a person having a heart attack, or being abducted, may have his or her information automatically sent to base station


62


so that the proper steps to remedy the emergency situation may be initiated. Base station


62


may be a private or a public entity or agency set up for the monitoring of persons. In addition, wireless communications may be with a parent of a small child or the adult child of an elderly adult person or parent, or any other person endeavoring to monitor monitored person


48


, so that monitoring may be continuously and automatically achieved.




Each object area network element


10


may also communicate, via its respective GPS unit


12


, with a global positioning satellite


60


in order to accurately track the position of the object area network elements


10


and thus the monitored person


48


.




Turning to

FIG. 3

, first object area network element


50


, second object area network element


52


, and third object area network element


54


each may communicate via their respective GPS units


12


with the global positioning satellite


60


, as is known in the art, in order to calculate the position of each of the first, second and third object area network elements


50


,


52


,


54


. In this manner, when an emergency situation is sensed by object area network elements


50


,


52


,


54


, the position of monitored person


48


may also be transmitted to base station


62


so that a proper response, such as a visit by police or an ambulance may be directed to the proper location quickly and efficiently. Since each of the first, second and third object area network elements


50


,


52


,


54


may independently calculate its position via its respective GPS unit


12


, the first, second and third object area network elements may also calculate the respective distances between each of the object area network elements


50


,


52


,


54


. For example, distance L


1


may be the distance between first object area network element


50


, and second object area network element


52


, while distance L


2


may be the distance between second object area network element


52


and third object area network element


54


, and distance L


3


may be the distance between third object area network element


54


and first object area network element


50


. By calculating the relative distances between the first, second and third object area network elements,


50


,


52


,


54


, an emergency situation may be triggered if one of the object area network elements


10


is removed from the monitored person


48


as monitored person


48


is abducted. If, for example, an attacker abducts a child who is being monitored, and the attacker removes one of the object area network elements


50


,


52


,


54


, but does not locate or have enough time to remove the other object area network elements, as a child is abducted, an emergency situation may be triggered as the relative distances between the first, second and third object area network elements


50


,


52


,


54


will indicate that an emergency situation has occurred. Additionally, monitored person


48


may have the ability to remove one of the object area network elements


50


,


52


,


54


such as, for example, third object area network element


54


from monitored person's


48


sneaker, so that monitored person


48


may, for example, wade in knee deep water at a pool or lake while leaving third object area network element


54


on the shore. In this scenario, first, second and third object area network elements


50


,


52


,


54


may calculate the respective distances between the elements and factor into the calculations that one of the object area network elements


50


,


52


,


54


is at a greater distance from the monitored person


48


than the other two, so that monitored person


48


may undertake an activity such as wading in knee deep water without triggering a false alarm when removing one of the object area network elements


50


,


52


,


54


.




Referring to

FIG. 4

, there is shown a monitored person


48


located at a first location A. Monitored person


48


may have, disposed on or near his or her body first object area network element


50


, second object area network element


52


and third object area network element


54


. As described above, the first, second and third object area network elements


50


,


52


,


54


may communicate with each other via wireless local object area network


56


. Object area network elements


50


,


52


,


54


may calculate their position or geographic location by way of GPS units


12


(see

FIG. 1

) which may communicate with a global positioning satellite such as, for example, first global positioning satellite


84


. Object area network elements


50


,


52


,


54


may alternatively communicate, using wireless communication units


14


, via a cellular or wireless communications network and, for example, first wireless communications tower


88


.




Personal data


82


of monitored person


48


may be stored in a first data base


78


. Personal data


82


may consist of any pertinent information related to monitored person


48


. Personal data


82


may include, but is not limited to, monitored person's


48


body temperature, pulse rate, speech patterns, and other pertinent biometric information. Also included in the personal data


82


may be notes normally taken during travel, areas of location which may be off limits, other persons whom monitored person


48


should not approach or be close to, as well as other pertinent information. Additionally, other information may be part of personal data


82


, such as, for example, monitored person's


48


social security number, driver license information, automobile registration information, banking information, and emergency contact information.




Personal data


82


may be located in first dynamic data base


78


. First dynamic data base


78


may be stored in first server


92


which, in turn, may be disposed in first base station


74


.




In an exemplary embodiment, first dynamic data base


78


may be a relational data base as is known by those skilled in the art, such that personal data


82


of monitored person


48


may be stored, referenced, and updated. First server


92


, may be a computer server capable of storing the personal data


82


in first dynamic data base


78


, as is known in the art. The specific choice of computer server is a matter of application specific design choice.




As personal data


82


of monitored person


48


may be stored in first dynamic data base


78


, the monitoring of monitored person


48


may be facilitated. For example, if monitored person


48


is a child, common or approved routes that the child may take, such as the trip from home to school, may be stored in personal data


82


of first dynamic data base


78


. If the child were to stray from the approved route because of, for example, becoming lost, or due to being abducted by an attacker, the position of the child could be determined by object area network elements


50


,


52


,


54


in first global positioning satellite


84


. The location of the child could be compared with information stored in personal data


82


and if the position of the child were to deviate from an approved route stored in personal data


82


, an alarm situation may be triggered with the proper response, such as the police or a rescue squad, being directed to the location of the child. Alternatively, a similar monitoring scenario could take place if monitored person


48


were an elderly person who were to become disoriented or lost and not able to find his or her way home. As described above with respect to the tracking of the child, the location of the elderly person could be determined and assistance could be dispatched.




Further, if monitored person


48


were to be in an automobile accident or other accident wherein monitored person


48


were to become unconscious or otherwise incapacitated, the identity of monitored person


48


, as well as any pertinent medical information, such as drug allergies, or medical conditions could be stored in personal data


82


and thus accessed by the proper authorities so that monitored person


82


, although unconscious or incapacitated, could be helped and attended to. Still further, in case of such an emergency, monitored person's


48


family could be automatically alerted to the emergency situation so that the injured person may not be considered to be missing or unidentified for an undue period of time.




Also, with regard to monitoring biometric characteristics of monitored person


48


, to determine if a medical emergency has occurred such as, for example, if the pulse rate is indicative of a heart attack or other serious condition, proper authorities may be alerted, so that help, such as an ambulance, may be automatically, efficiently, and quickly dispatched. Information included as part of personal data


82


and first dynamic data base


78


may be communicated to and from object area network elements


50


,


52


,


54


via wireless communications. Different biometric profiles based on the activities that monitored person


48


is undertaking may be used. For example, if monitored person


48


is sitting at a desk, a certain heart rate may be considered normal. However, if monitored person


48


is, for example, jogging, which could be determined through GPS unit


12


and global positioning satellite


84


, a different heart rate profile may be taken from personal data


82


and dynamically updated on object area network elements


50


,


52


,


54


such that a false alarm on an increased heart rate or body temperature would not occur.




Accordingly, by having personal data


82


stored in first dynamic data base


78


, monitored person


48


does not need to carry on his or her person information regarding medical histories, automobile information, social security information, and banking information.




If monitored person


48


were to travel from location A located, for example, on the East Coast of the United States to location B located, for example, on the West Coast of the United States, monitored person's


48


movements may be tracked by use of GPS units


12


on object area network elements


50


,


52


,


54


in conjunction with first global positioning satellite


84


and second global positioning satellite


86


. Further, while the positioning system has been described with respect to a first and second global positioning satellite and first and second communications towers for descriptive purposes, the present invention may be used in conjunction with more than two satellites or towers, the specific number used being a matter of design choice as is known by those skilled in the art.




In an exemplary embodiment, as monitored person


48


moves from location A to location B, the personal data


82


related to monitored person


48


may move from first dynamic data base


78


, located in first server


92


, located in first base station


74


, located relatively within the geographic region of location A, to second dynamic data base


80


located in second server


94


which, in turn, is located in second base station


76


. Personal data


82


may be moved or transferred from first dynamic database


78


to second dynamic database


80


via a wireless communications network or other known network. In this manner, personal data


82


of monitored person


48


may follow monitored person


48


as he or she moves from location A to location B. Accordingly, if monitored person


48


were to travel from location A on, for example, the East Coast of the United States, to location B at, for example, the West Coast of the United States, monitored person's


48


, personal data


82


would follow monitored person


48


in his or her travels and would be stored in second dynamic data base


80


relatively locally to monitored person's


48


location.




If monitored person


48


were to have an emergency situation such as an accident, where monitored person


48


to become unconscious or incapacitated, while in location B, the pertinent information and help could be accessed quickly by having personal data


82


stored in second dynamic data base


80


located relatively close to the actual position of monitored person


48


at location B. In an emergency situation, the proper authorities, such as an ambulance squad or police, may be notified from second base station


76


so that assistance may be quickly and efficiently provided.




By having personal data


82


follow monitored person


48


from location A to location B, communication pathways, such as communication networks, may be freed up as less wireless traffic is created when personal data


82


in second dynamic data base


80


is accessed through second wireless communications tower


90


when monitored person


48


is at location B than if personal data


82


were to be accessed from first dynamic data base


78


located nearer to location A. In other words, if personal data


82


must be retrieved from a relatively far location, more communications traffic is created as the signal must be relayed through multiple cellular or wireless communication cells or hops and any necessary intervening communication networks. Also, by having personal data


82


stored at a location relatively close to the position of monitored position


48


, the speed of communication between object area network elements


50


,


52


,


54


, or any authorized third party, and the personal data


82


may be increased.




While the communication pathway is described as being a cellular communications network, other communications networks, such as satellite communications, other wireless communications systems, telephone communications, or computer network communications may be used as well. In addition, a single type of communications network need not be used, as a combination of communication networks may be employed. The type or combination of type of communications networks being used is an application specific matter of design choice.




In an exemplary embodiment, wireless communications network traffic may also be reduced by moving personal data


82


from first dynamic data base


78


to second dynamic data base


80


during off peak or low traffic time periods. If, for example, monitored person


48


moves from location A to location B, this movement may be tracked by GPS units


12


on object area network elements


50


,


52


,


54


and the first global positioning satellite


84


, and second global positioning satellite


86


. If this movement takes place during a peak communications time period or a high communication traffic period, movement of personal data


82


from first dynamic data base


78


to second dynamic data base


80


may be delayed such that personal data


82


is moved during a relatively low communications traffic time period so that communication traffic minimization is facilitated.




Further, referring again to

FIG. 4

, if personal data


82


is moved from first dynamic data base


78


to second dynamic data base


80


, this information may be deleted from first dynamic data base


78


so that redundant information need not be stored. Once monitored person


48


returns from location B back to location A, personal data


82


may be moved from second dynamic data base


80


back to first dynamic data base


78


with the personal data


82


being deleted from second dynamic data base


80


. In this manner, in addition to facilitating the quickening of communications between the stored personal data


82


and the object area network elements


50


,


52


,


54


, and minimizing wireless communications traffic, the need for computer storage capabilities is minimized as personal data


82


moves with monitored person


48


and is only stored at a location near monitored person


48


, with personal data


82


being deleted from other locations so that overall storage and computer capacity may be used more efficiently.




While the above described examples have been directed to a scenario with only two locations, location A and location B, for ease of explanation and simplicity of discussion, the dynamic data base system may be used in conjunction with a wide array of dynamic data bases located throughout a region, country, or throughout the world. Dynamic data bases might be located, for example, in each county or in each state. In an exemplary embodiment, dynamic data bases may be set up in a hierarchical topology wherein servers are located at the county level at one hierarchic level and then at the state level at another hierarchic level with information being transferred from a county level to a state level and then to another county or state dynamic data base.




Alternatively, personal data


82


may be stored in multiple dynamic databases if monitored person


48


were to frequently visit a certain geographic location or region. Personal data


82


may be retained for a certain amount of time before being deleted. In this manner, an efficient balance between total storage usage (at the various server locations) and the limiting of communication network traffic may be achieved.




In an exemplary embodiment, personal data


82


may follow monitored person


48


in his or her travels, continuously and automatically, without the need for manual adjustment or updating of data bases. As monitored person's


48


location is tracked during his or her travels, personal data


82


may be automatically and continuously referenced and updated.




While object area network elements


10


have been described with respect to monitoring and tracking persons, in another embodiment, object area network elements


10


may be used to monitor objects other than persons. Turning to

FIG. 5

, a gun or unwanted object


100


is shown. A first unwanted object sensor


102


, a second unwanted object sensor


104


, and a third unwanted object sensor


106


may be disposed on unwanted object


100


. Unwanted object sensors


102


,


104


,


106


may be temperature sensors, pressure sensors, or other sensing units. The temperature and pressure sensors may be any type suitable for the application as would be determined as a matter of application specific design choice by one skilled in the art. In an exemplary embodiment, unwanted object sensing units


102


,


104


,


106


may be disposed on an integrated circuit chip having dimensions such that unwanted object sensor units


102


,


104


,


106


may be integrated into the unwanted object or gun


100


. In an exemplary embodiment unwanted object sensors


102


,


104


,


106


may be disposed on object area network elements having, in addition to a temperature sensing unit


22


and a pressure sensing unit


24


, a GPS unit


12


for determining the positioning of the unwanted object


100


as well as a wireless communications unit


14


for communicating with a base station via a wireless communications network.




In an exemplary embodiment, unwanted object sensors


102


,


104


,


106


may monitor changes in pressure and temperature such that when a gun or unwanted object


100


is fired or discharged, the temperature and pressure sensors


102


,


104


,


106


would be triggered.




In an exemplary embodiment, when unwanted object


100


is fired, and sensors


102


,


104


,


106


detect the firing, the position of unwanted object


100


may be determined by GPS unit


12


of object area network element


10


and this data may be communicated via wireless communications unit


14


via a wireless communications network to a first base station


74


. Unwanted object


100


may have corresponding unwanted object data


110


stored in first dynamic data base


78


and first base station


74


. When unwanted object


100


is fired, the information regarding the firing of unwanted object


100


, as well as its position, may be updated and unwanted object data


110


in first dynamic data base


78


.




Unwanted object data


110


may include to whom the gun


100


is registered, as well as areas where unwanted object


100


is permitted to be taken, as well as locations where unwanted object


100


is not permitted to be taken. Also, the position of unwanted object


100


may be determined and if unwanted object


100


is in a location where firing should not take place, such as in a school zone, emergency personnel such as an ambulance squad or the police may be dispatched to the location of unwanted object


100


.




Further, if unwanted object data


100


includes owner registration information, and the registered owner of unwanted object


100


has object area network elements disposed on his or her person, as discussed above, relative locations of the registered owner of unwanted object


100


and the location of unwanted object


100


may be calculated to determine if the owner of unwanted object


100


is in the vicinity of unwanted object


100


or if unwanted object


100


may have been stolen or otherwise removed from the possession of the owner of unwanted object


100


.




In an exemplary embodiment, a child may be a monitored person


48


, having object area network elements disposed on his or her person such that the monitored person


48


may be tracked via a GPS receiver system. Automatic monitoring may be initiated whereby the position of unwanted object


100


is monitored with respect to the position of monitored person or child


48


, such that if unwanted object


100


were to come within a distance determined to be too close to monitored person or child


48


, an emergency condition would be initiated and the proper authorities, such as the police, could be quickly dispatched to the location of the child. Additionally, if respective locations of the monitored person or child


48


and the unwanted object


100


are determined at timely intervals, the relative velocity vectors of the two may be calculated such that a meeting of the monitored person


48


and the unwanted object


100


may be anticipated before a critical distance is reached. Additionally, ex-convicts may be fitted with the object area network elements as part of an early release or parole requirement. In an exemplary embodiment, besides monitoring the position of an ex-convict, the position of the ex-convict now may be calculated with respect to the location of unwanted object


100


, such that if the distance between the two becomes too small, indicating that an ex-convict has unwanted object


100


in his or her possession, the proper authorities, such as the police, may be automatically dispatched in a timely and efficient manner.




Additionally, unwanted object


100


may be fitted with unwanted object disabling unit


108


which may be remotely activated via the wireless communications network such that if it is determined that unwanted object


100


is in the wrong hands, unwanted object


100


may be remotely disabled via unwanted object disabling unit


108


.




Additionally, the monitored person or potential victim


48


may be alerted to the presence of unwanted object


100


via wireless communication to an object area network element on the potential victim's person via the alerting unit


18


of object area network element


10


. Alerting unit


18


may be a speaker capable of sounding an alarm or a speaker that would allow monitored person


48


to communicate via a wireless communications network and give voice instructions or alternatively, alerting unit


18


of object area network element


10


may be a flashing light, or vibrating unit as is used in pagers, a thermal unit that changes temperature to alert the potential victim or any other alerting unit as is known by those skilled in the art.




In an exemplary embodiment, sensing units


102


,


104


,


106


and object area network elements


10


on unwanted object


100


may be integrated into unwanted object


100


such that they may not be easily removed and, if they are removed, unwanted object


100


may be disabled.




Turning to

FIG. 6

, another embodiment of the present invention is shown wherein a space area network is shown. In an exemplary embodiment, unwanted object or gun


100


may not have any sensors


102


,


104


,


106


or object area network elements


10


, as described in the previous embodiments. The space area network may be disposed in order to facilitate protection of those people located at a space location


122


, such as a school, from a person carrying an unwanted object or gun


100


. Space area network sensors may have eddy current sensors capable of sensing the amount of metals present in a small gun or unwanted object


100


. Space area network sensors


124


may also have infrared (IR) sensors capable of sensing the body heat of a person. The IR sensors of space area network sensors


124


may be any type known to those skilled in the art, the exact specifications of which are a matter of application specific design choice. Space area network sensors


124


may also be formed on space area network elements


125


which may communicate via wireless communications with a base station


74


having a first server


92


, having data base


78


and space area network data


112


.




In an exemplary embodiment, space area network elements


125


with space area network sensors


124


may be disposed in a pattern of concentric rings surrounding a space location or school


122


. In an exemplary embodiment, space area network elements and space area network sensors may be disposed in a first or inner sensor circle


126


, a second or middle sensor circle


128


and a third or outer sensor circle


130


. Sensor circles


126


,


128


,


130


define space area network regions such as, for example, first space area network zone


132


, second space area network zone


134


, third space area network zone


136


and outer space area network zone


138


.




In an exemplary embodiment, space area sensors


124


and space area network elements


125


may be disposed buried under the ground such that they may not be easily identified or removed or tampered with by persons carrying an unwanted object or gun


100


. Space area network elements


125


with space area network sensors


124


may be spaced about first, second and third sensor circles


132


,


130


,


128


, such that the person trying to bring an unwanted object


100


near space location or school


122


may trigger eddy current sensor or IR sensor when traversing each of the sensor circles


126


,


128


,


130


.




As the unwanted object


100


is detected passing outer third sensor circle


130


, this information may be communicated via a wireless communications network to space area network data


112


and dynamic data base


78


. A precautionary alarm may be communicated at this time to the proper authorities such as police or to the occupants of space location or school


122


. Alternatively, if the outer third sensing circle


130


is traversed, no warning may be issued upon this situation. As the unwanted object


100


is brought across the second sensor circle


128


, a heightened state of alarm may be automatically triggered to the proper authorities such as the police and to the occupants of space location or school


122


. Finally, if unwanted object


100


traverses first or inner sensor circle


126


, a full state of emergency may be instituted and the proper authorities, such as the police, as well as the occupants of space location or school


122


, may be alerted to a full alarm situation. In this manner, many tragic shooting incidents at schools and other such locations may be avoided.




Additionally, if several unwanted objects


100


should pass through a sensor circle


130


, the heightened state of awareness might be initiated.




Turning to

FIG. 7

, another embodiment of the present invention is depicted wherein a space area network


121


is shown. As in a previously discussed embodiment, space area network elements


124


may be disposed in a, for example, circular pattern such as first sensor circle


126


defining first space zone


132


for the protection of space location or school


122


. As is the case with the above-discussed embodiment, the space area network


121


facilitates the protection of persons at space location


122


from unwanted object or gun


100


. As an alternative to, or in addition to, the use of eddy current sensors, however, space area network sensors each may have an interrogation unit


142


. Interrogation unit


142


may transmit an interrogation signal


140


to facilitate identification of the presence of unwanted object


100


. Interrogation signal


140


may be any signal suitable for determining the presence or proximity of unwanted object


100


. Interrogation signal


140


may be, for example, an RF signal, an IR signal, or other suitable signal as is known by those skilled in the art.




Unwanted object


100


may have an identifier unit


144


for facilitating the identification of unwanted object


100


by a space area network sensor


124


. Identifier unit


144


may be a passive transponder device of the type known in the art such that no signal is transmitted by identifier unit


144


unless interrogation signal


140


is received at unwanted object


100


. In this embodiment, a space area network sensor


124


may transmit interrogation signal


140


, and once this signal is received at unwanted object


100


, identifier unit


144


may transmit response signal


146


, which may in turn be received at a space area network sensor


124


. In this manner, the space area network sensors


124


may identify the presence of an unwanted object


100


. Once the presence of unwanted object


100


is detected, space area network sensor


124


may communicate via wireless communications path


148


and, for example, first wireless communications tower


88


to alert a base station


74


(see

FIG. 4

) so that the proper authorities, persons, or entities may be contacted.




Returning to

FIG. 7

, alternatively, identifier unit


144


of unwanted object


100


may be an active device, broadcasting announcement signal


150


at regular, predetermined, or otherwise initiated intervals. In this embodiment, identifier unit would not wait for interrogation signal


140


before transmitting, but could transmit announcement signal


150


at certain time intervals to facilitate the determination of the proximity of unwanted object


100


by space area network sensors


124


. Additionally, unwanted object


100


may have a GPS portion (not shown) for communicating with GPS satellite


84


via GPS communication path


152


to determine position information regarding unwanted object


100


. Accordingly, the space area network may facilitate protection of those people located at a space location


122


, such as a school, from a person carrying an unwanted object or gun


100


.




Thus, while there have been shown and described and pointed out fundamental novel features of the invention as applied to exemplary embodiments thereof, it would be understood that various omissions and substitutions and changes in the form and details of the disclosed invention may be made by those skilled in the art without departing from the spirit of the invention.
