Description

FIRST RESPONDER TRACKING AND COMMUNICATION SYSTEMCROSS-REFERENCE TO RELATED APPLICATIONThe present application claims priority to U.S. Provisional Patent Application with Ser. No 63 / 436,157, filed on Dec 30, 2022, the disclosure of which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0001] The present invention generally relates to tracking and communication system, and, more particularly, to first responder tracking and communication system and method.BACKGROUND

[0002] First responders are organizations and personnel that provide law enforcement, safety and protection services to the public. The first responders include law enforcement officers, and fire and safety personnel, for example, police, sheriff, highway patrol, detectives, special law enforcement, firefighters, war fighters, emergency medical services personnel, Red Cross personnel, and other emergency workers.

[0003] During an indoor incident, the first responders need to deal with number of unpredictable situations, for example, building structure, intensity of disaster and number of responders needed may increase depending upon the situation. In these situations, the responders need situational awareness to successfully complete the operation without any loss of personnel. For example, during a fire incident, if a door to a particular room is blocked and a responder is trapped in the room with the civilian. The incident commander, or a fellow first responder in the vicinity of the room needs to be aware of thesituation to save the trapped responder and civilian. However, with the existing conventional system, the trapped responder can only transfer message that he has trapped inside room. The conventional system includes talk-radios to communicate with fellow first responders or incident commander. Sometimes, depending upon the structure and location of the room, for example, an underground room, even transferring message is not possible. The incident commander and fellow first responders have to search through the whole building to find the location of the trapped first responder and civilian. However, during such situation, searching the entire building is not even an option and mostly result in casualties.

[0004] Few patent application reference attempts to address the problems cited in the background as prior art over the presently disclosed subject matter and are explained as follows.

[0005] A prior art US8706414 assigned to Benjamin E. Funk et al. entitled “method and system for locating and monitoring first responders” discloses methods and systems for locating and monitoring the status of people and moveable assets, such as first responders. The system and method use inertial navigation to determine the location, motion and orientation of the personnel or assets and communicates with an external monitoring station to receive requests for location, motion orientation and status information and to transmit the location, motion orientation and status information to the monitoring station.

[0006] Another prior art US11051 156 assigned to Patrick O'Connor et al. entitled “tracking and accountability device and system” discloses a first personal tracking unit (PTU) is configured to be worn to determine their location within a structure. The PTU is in communication with a wireless communication network and it is operative to transmit signals of the locationdata to a command unit. The system generates a visual illustration of an ambient temperature data and the location data obtained from each of the first and second PTU in the form of a map. The measurements from an accelerometer and gyroscope or MEMS sensor allow the system to determine the position and orientation of the PTU. However, the existing system lacks to ensure seamless communication and tracking in any type of environment.

[0007] Therefore, there is a need for a system and a method that facilities to track the location of the first responders in both indoor and outdoor environment. Further, the system and method need to enable communication among the first responders and with the incident commander. Further, the system and method need to facilitate the first responders to track the location of other first responders in the incident environment and enable to communicate with the other first responders in the incident environment.SUMMARY
