REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims an invention which was disclosed in Provisional Application Number U.S. 61/516,113 filed Mar. 30, 2011, entitled “Proximity Sensors”. The benefit under 35 USC §119(e) of the United States provisional application is hereby claimed, and the aforementioned application is hereby incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to tracking devices, and more particularly, to functions that allows multiple “TDS” (tracking device software) units to work together keeping track of the items needing to be tracked and located. 
       BACKGROUND 
       [0003]    In September 2006-October 2008 the initial idea and concept was developed after reading a Southwest Airlines article in In-Flight magazine stating that over 12,000 laptop computers were misplaced, left or forgotten in LAX airport every week. $30 Billion worth of mobile phones lost or misplaced last year . . . . So then how much is it with Laptops, IPods, cameras, pocketbooks, keys . . . . Proximity Sensors is based on networking units to create methods and applications enabling units with features similar to: 
       Monitoring Tracking Locate Update Manage 
       [0004]    The concept prototype was designed and produced with limited capabilities in 2010 by Davison Inventions. 
         [0005]    Leveraging standard materials, methods, technologies and application logic currently in production with an existing large market. Example: GPS/WiFi/Free In the Air . . . this invention will be able to reach local, national and global markets through tracking items in various settings: 
         [0006]    1. Personal items 
         [0007]    2. Children 
         [0008]    3. Travel 
         [0009]    4. Business Items/Asset Tracking/Location Security 
         [0010]    5. Implement as software using embedded existing technology and components 
         [0011]    6. Work with manufacturers to integrate “TDS” chip into existing product lines 
         [0012]    7. Government/Asset Tracking/Item Location Security/Prison Inmate Monitoring 
       SUMMARY OF APPLICATION 
     Application Example 
     General Use (As shown in FIG.  1 ) 
       [0000]    
       
         
           
             A) Customer purchases 4 TDS units to track or locate the following:
           1. Laptop computer   2. Mobile phone/PDA   3. Car Keys   4. Wallet   
         
             B) Customer needs to activate the 4 TDS units by touching the 4 TDS units to each other.
           *Note that if customer purchased all 4 TDS units as a package, then the 4 units have already been activated prior to shipping from factory.   
         
             C) Customer attaches TDS unit to each of the 4 items noted in “A” above. 
             D) Now all 4 items with the attached TDS unit will alert customer anytime the item is out of the allowable range 15-90 feet (selectable ranges, default is 30 ft.) of the entire group. 
             E) Customer purchased digital camera and wants to add tracking and locating capabilities. 
             F) Customer purchases a single TDS unit to add to the existing group of 4 items currently activated. 
             G) Customer activates the single TDS unit by touching the TDS unit to any of the existing active TDS units. 
             H) Customer attaches the single TDS unit to the digital camera. 
             I) Now the customer has 5 items in the TDS group to track and locate:
           1. Laptop Computer   2. Mobile Phone/PDA   3. Car Keys   4. Wallet   5. Digital Camera   
         
             Note—If any of the 5 items with the TDS units attached is 30 feet apart then the TDS units will alert customer. 
             J) Customer decided not to track and locate item #1, Laptop computer. To deactivate the TDS on the laptop the customer can do the following:
           1. Push and hold the OFF button for 5 seconds.   2. Do nothing and the unit will remove itself after it has no communication with group for 5 minutes.

       Application Example 
     Specialized Use 
     Application 
     Track Luggage 
       [0000]    
       
         
           
             A) Customer purchases a “TDS” travel package that has 2-4 units designed to activate with functions specific to monitor and tracking luggage. 
             B) Customer activates the travel units by touching the units to an existing activated group unit. This will add the travel units selected to the monitor and tracking group. 
             C) Customer attaches TDS units that have been activated to each piece of luggage. 
             D) The travel units are now active and assigned in a monitor and tracking group but need to be enabled to start the luggage specific mode. 
             E) “Typical” process would be to enable the Hibernate/Luggage mode when actually checking in the luggage at the terminal. Terminal=Airport/Cruise/Bus . . . . 
             F) Please note that when any TDS unit is activated all units communicate and this allows the customer to activate features from any unit. 
             G) To enable all the luggage units at one time press the Hibernate/Luggage button and hold for 5 seconds. 
             H) All of the luggage units will flash and produce an audible alert thus confirming the successful change of mode. 
             I) At this point the luggage units are in Hibernate mode and waiting for the Locate message to be sent. Once received the luggage units will send out a return proximity message. 
             J) The unit that activated the Locate function for the luggage will receive the proximity message. 
             K) At this point the customer will know how many of the luggage units are in close proximity.
           Example: Customer is settled in his/her seat on the plane and has located all luggage placed under the plane in the luggage storage area.   
         
             L) If a luggage unit has not responded, the customer can inform the flight attendant.

             1. To begin a group
           Touch any two units together until either the audio alerts “Activated New Group” or the LED&#39;s stay solid green for 5 seconds.   
         
             2. Add units into existing group
           Touch unit to existing activated unit
               Or   
               Press the OFF/ON button twice
               Audible &amp; LED will indicate status   
               
         
           
         
       
     
         [0092]    Methods to Deactivate “TDS” units:
       Same process as above with audible and LED indication status.
