Real-time, two dimensional (2-D) tracking of first responders with identification inside premises
First Claim
1. A system comprising:
- a plurality of active tags, each active tag having an identification;
a plurality of wearable communicator units in communication with each other, each wearable communicator unit associated with one of the plurality of active tags, and each wearable communicator unit comprising a display; and
a plurality of sensor units comprising an ultra-wideband (UWB) radar imaging system, wherein each of the plurality of sensor units is in communication with at least one of the plurality of wearable communicator units, and wherein the plurality of sensor units is configured to;
operate in a static mode that gathers information to depict a layout of a field of operations;
communicate a layout depiction to at least one of the plurality of wearable communicator units;
operate in a dynamic mode that searches for motion of a subject using edge detection based on a depth resolution of about 3 picoseconds of the UWB radar imaging system, reads at least one of the active tags associated with at least one of the plurality of wearable communicator units, and locates a position of the at least one wearable communicator unit; and
communicate a position of the subject and the position of the at least one wearable communicator unit on the layout depiction to the at least one wearable communicator unit, whereinthe at least one wearable communicator unit displays the layout depiction, a subject location on the layout depiction, a wearable communicator unit location on the layout depiction, and active tag identification information on a display of the at least one wearable communicator unit.

Abstract
A combination of active reader tags and ultra wideband (UWB) radar systems provide real-time monitoring of first responders, with identification of each team member using active tags, and detection of victims or other subjects using motion or breathing detection, in a field of operations such as a building affected by fire or hazardous material or search and rescue mission area. Initially, a cluster of miniaturized radars (sensors) act in a static mode of operation, gathering static radar information used to depict a constructed layout of the premises. The cluster of radars then operate in a dynamic mode that detects motion or breathing of multiple subjects inside the field of operations. With dual mode operation the system can read the active tags identification, and by triangulation, display the position of each first responder with its identification and positions of subjects on a composite image of the constructed layout.
