Firefighter location and rescue equipment employing path comparison of mobile tags
First Claim
1. A rescue system comprising:
- at least one mobile tag to be carried by a person potentially in need of rescue;
one or more fixed devices, each of said one or more fixed devices in radio frequency communication with said at least one mobile tag;
said rescue system configured for determining mobile tag signal property measurements indicative of electromagnetic propagation between said at least one mobile tag and said one or more fixed devices;
said rescue system further comprising a database, said rescue system configured for storing said mobile tag signal property measurements in said database in association with a path variable indicative of a path taken by said at least one mobile tag;
said rescue system further comprising a rescue tag to be carried by a rescuer;
each of said one or more fixed devices in radio frequency communication with said rescue tag;
said rescue system configured for determining rescue tag signal property measurements indicative of electromagnetic propagation between said rescue tag and said one or more fixed devices;
said rescue system configured for comparing said rescue tag signal property measurements with said mobile tag signal property measurements from said database to determine a comparison data set indicating a relative position of said rescue tag to said path taken by said at least one mobile tag.

Abstract
The present application describes firefighter location and rescue equipment (FLARE) comprising: a plurality of tag transmitters, a first tag transmitter of said plurality of tag transmitters emitting a first signal, a plurality of locator-receivers receiving said first signal, each of said plurality of locator receivers determining a first set of signal characteristic data for said first signal, a computer compiling said first set of signal characteristic data in a reference database along with an associated path variable, a second tag transmitter of said plurality of tag transmitters emitting a second signal, a plurality of locator-receivers receiving said second signal, each of said plurality of locator receivers determining a second set of signal characteristic data for said second signal, said computer comparing said second set of signal characteristic data to the reference database, said computer displaying said comparison for evaluating the location of said second tag transmitter relative to a path taken by said first tag transmitter.

15. A rescue method comprising:
-
providing a person with a mobile tag carried by said person; said person traversing a path in accordance with at least one path variable; providing one or more fixed devices in radio frequency communication with said mobile tag; determining mobile tag signal property measurements and recording said signal property measurements in a database, said signal property measurements recorded in association with a path variable, said path variable indicative of a path taken by said mobile tag, said mobile tag signal property measurements indicative electromagnetic propagation between said mobile tag and said one or more fixed devices; providing a rescuer with a rescue tag carried by said rescuer; said rescuer tag in radio frequency communication with said one or more fixed devices; determining rescue tag signal property measurements, said rescue tag signal property measurements indicative of electromagnetic propagation between said rescue tag and said one or more fixed devices; comparing said rescue tag signal property measurements with said mobile tag signal property measurements from said database to determine a comparison data set indicating a relative position of said rescue tag to said path taken by said at least one mobile tag. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
