Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to perimeter alarms and more particularly pertains to a new perimeter security system for providing a security alarm for people leaving or entering a predetermined area. 
     2. Description of the Prior Art 
     The use of perimeter alarms is known in the prior art. More specifically, perimeter alarms heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     Known prior art includes U.S. Pat. Nos. 5,486,814; 5,619,187; 5,408,222; 5,748,080; 5,821,874; and Des. 374,190. 
     While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new perimeter security system. The inventive device includes a main sensor unit, wearable by a user, which provides an alarm if the wearer breaks a boundary of the predefined area; a perimeter defining assembly for providing an indication of the boundary of the predefined area; and a remote unit for receiving a signal from the main sensor unit that the boundary of the predefined area has been broken, which provides an alarm for a caretaker. 
     In these respects, the perimeter security system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of providing a security alarm for people leaving or entering a predetermined area. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of perimeter alarms now present in the prior art, the present invention provides a new perimeter security system construction wherein the same can be utilized for providing a security alarm for people leaving or entering a predetermined area. 
     The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new perimeter security system apparatus and method which has many of the advantages of the perimeter alarms mentioned heretofore and many novel features that result in a new perimeter security system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art perimeter alarms, either alone or in any combination thereof. 
     To attain this, the present invention generally comprises a main sensor unit, wearable by a user, which provides an alarm if the wearer breaks a boundary of the predefined area; a perimeter defining assembly for providing an indication of the boundary of the predefined area; and a remote unit for receiving a signal from the main sensor unit that the boundary of the predefined area has been broken, which provides an alarm for a caretaker. 
     There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

     As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention. 
     Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way. 
     It is therefore an object of the present invention to provide a new perimeter security system apparatus and method which has many of the advantages of the perimeter alarms mentioned heretofore and many novel features that result in a new perimeter security system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art perimeter alarms, either alone or in any combination thereof.

     The perimeter defining assembly  70  provides an indication of the boundary of the predefined area. 
     The remote unit  50  receives a signal from the main sensor unit  20  that the boundary of the predefined area has been broken when the main sensor unit  20  passes the perimeter defining assembly  70 . The remote unit  50  provides an alarm for a caretaker. 
     In an embodiment, the main sensor unit  20  further comprises a housing  22 , sensor assembly  21 , transmitter assembly  24 , water activated switch  25 , vibration assembly  26 , at least one strobe light  27  and an audible alarm assembly  28 . The housing  22  is preferably wearable by the user. The sensor assembly  21  is positioned substantially within the housing  22 . The sensor  21  detects when the main sensor unit  20  passes the perimeter defining assembly  70 . The transmitter assembly  24  is used for sending a signal to the remote unit  50  indicating the main sensor unit  20  has broken the boundary of the predefined area. The water activated switch  25  facilitates activating an alarm when the main sensor unit  20  contacts water. The housing  22  includes at least one aperture  23  for facilitating water flow to the water activated switch  25  when the main sensor unit  20  contacts water. Preferably, the interior of the housing  22  is divided into two portions: a first portion for the water activated switch  25  and a substantially water-proof portion for the remaining parts of the main sensor unit  20 . The vibration assembly  26  provides a tactile alarm to the user when the boundary of the predetermined area is broken such that the user is aware of the violation of the boundary and may return to an appropriate area. The strobe light  27  is positioned on an exterior surface of the housing  22  such that the strobe light  27  is visible when activated. The strobe light  27  is activated when the boundary of the predetermined area is broken facilitating visual location of the user.
