Building occupant tracker

Abstract

A building occupant tracker for tracking the location of an occupant in a building by tracking a smart device associated with the occupant at a location server.

What is claimed is: 
     
         1 . A smart device with an on-board unit (OBU), comprising:
 a transmitter;   a memory having unique data associated with the OBU;   a location determination unit that generates location data associated with the smart device;   a timer;   a controller coupled to them memory and the transmitter that transmits a location message in response to a timer, where the location message contains location data and the unique data.   
     
     
         2 . The smart device of  claim 1 , where the location determination unit is a global positioning system receiver. 
     
     
         3 . The smart device of  claim 1 , where the location data is longitude and latitude coordinates. 
     
     
         4 . The smart device of  claim 1 , where the location data further includes elevation data. 
     
     
         5 . The smart device of  claim 1 , where the location message is at least partially encrypted. 
     
     
         6 . The smart device of  claim 1  where the OBU is an application located in a memory of the smart device executed by the controller. 
     
     
         7 . The smart device of  claim 1 , where the location message is formatted for receipt by a location server. 
     
     
         8 . A remote location node, comprising:
 a receiver;   a transmitter;   a controller coupled to the receiver that is able to receive identification information from an identification device associated with a user and format a location message that appears to originate with the identification device that is transmitted by the transmitter for receipt by a location server.   
     
     
         9 . The remote location node of  claim 8  where the identification information contains authentication information. 
     
     
         10 . The remote location node of  claim 8  where the location message contains location data. 
     
     
         11 . The remote location node of  claim 10 , where the location message contains additional data. 
     
     
         12 . The remote location node of  claim 11 , where at least a portion of the additional information is encrypted. 
     
     
         13 . The remote location node of  claim 8  where the identification data is a OBU formatted location message. 
     
     
         14 . A method for tracking an on-board unit (OBU) in a building, comprising the steps of:
 generating location data in a location determination unit in a smart device that also has unique data;   setting a timer in response to a controller;   formatting a location message containing the location data and unique data by a controller in the smart device in response to the timer; and   transmitting the location message by a transmitter in response to the controller.   
     
     
         15 . The method for tracking of  claim 14 , where generating location data with the location determination unit further includes determining location data with a global positioning system receiver. 
     
     
         16 . The method for tracking of  claim 14 , where the location data is longitude and latitude coordinates. 
     
     
         17 . The method for tracking of  claim 14 , where the location data further includes elevation data. 
     
     
         18 . The method for tracking of  claim 14 , includes encrypting at least a portion of the location message by the controller where the location message is at least partially encrypted. 
     
     
         19 . The method for tracking of  claim 14  includes executing an OBU application stored in memory of the smart device by the controller. 
     
     
         20 . The smart device of  claim 14 , includes
 formatting the location message for receipt by a location server.   lease replace the informal figures filed at the PCT stage with the formal replacement figures enclosed herein. No new matter has been introduced.
