or optically recorded by a sensing apparatus 105 it is assumed that the sensing apparatus 105 is embedded in a wtru as soon as the sensing apparatus 105 is activated the wtru identifies its own location and creates a field of usage fou the creation of the fou marks the location boundary of the sensing apparatus in terms of position coordinates the sensing apparatus 105 may include various sensing devices such as a zoom lens 120 for gathering optical information of a target 150 a microphone 125 for gathering audible information regarding the target 150 or the like these various sensing devices 120 125 may be used in determining the fou the sensing apparatus 105 may analyze the location of the target 150 with the help of the fou the sensing apparatus attempts to identify if a communication path is available to the target 150 if a direct communication path as shown in fig1 is available through some form of local ad hoc peer to peer network it will try to alert the communicating devices e g cell phone 110 pager 115 associated with the target 150 by sending an electronic warning signal 130 if a direct communication path is not available the sensing apparatus 105 sends the fou information along with the result of analysis i e location image sound of the target 150 to a network server 205 as shown in fig2 the network server 205 attempts to identify the target 150 which may require the network server 205 having to request information from servers of other operators personal information databases or the like if the network.
