Six firefighters misplaced their lives responding to a hearth in a century-old, deserted warehouse in Worcester, Massachusetts, in December 1999. Worried that civilians have been trapped inside, rescue groups initiated a speedy intervention; however, unfamiliar with the structure of the constructing, the smoke-filled warehouse turned a labyrinth for people who entered. Unfortunately, the courageous people that answered this name have been unable to find any exits earlier than they ran out of air.
We nonetheless bear in mind them greater than 20 years later, and this incident—together with tons of in the years since—served as the catalyst for groundbreaking new Department of Homeland Security Science and Technology Directorate (S&T) monitoring and placement expertise. Precision Outdoor and Indoor Navigation and Tracking for Emergency Responders (POINTER) will quickly enable companies to pinpoint their firefighters to inside centimeters, serving to to navigate them shortly and safely out of doubtlessly disorienting emergency situations.
“From containing small kitchen fires to carrying civilians out of burning homes to securing local infrastructure, first responders put their lives on the line daily to ensure the safety of their communities,” stated Greg Price, who leads S&T’s first responder analysis and improvement packages. “The reality is, even with all of the advances made in firefighting technology, we still lose far too many firefighters each year. We want them to know that we have their backs, that we are working to give them the tools they need to ensure their own safety. POINTER is that solution.”
Throughout the improvement of POINTER, S&T has not solely been designing the expertise for responders, however with them as nicely—together with firefighters in Worcester.
“We have tested many different technologies, finding them not very accommodating to our needs for one reason or another” stated Chief Michael Lavoie of the Worcester Fire Department. “Mostly, the equipment was bulky and would work in some situations, but not all. However, experimentation over the last 21 years has brought technological advances in this area and we are pleased to have been asked to field test the POINTER system.”
S&T has collaborated with the NASA Jet Propulsion Laboratory (JPL) in Southern California and first responder stakeholders since 2014 to develop POINTER, a wearable and transportable, cost-effective monitoring and placement expertise that leverages cutting-edge science to succeed the place current merchandise might fail.
For occasion, applied sciences that use GPS, acoustic sensors, radio location, radio-frequency identification, ultra-wideband radar or different strategies usually lose sign or face place drift in line-of-sight denied environments. Many can’t penetrate by means of sure constructing supplies and even attain underground. POINTER can do all of this and extra, making it each extra correct and dependable.
POINTER makes use of magnetoquasistatic (MQS) fields to three-dimensionally monitor and find responders in low-visibility environments. “MQS fields are not blocked or reflected by the materials found in most buildings due to weak response of the materials to magnetic-dominant fields,” stated Dr. Darmindra D. Arumugam, principal investigator and senior technologist at NASA JPL. Dr. Arumugam developed the idea, method and algorithms that may analyze each the electrical and the magnetic parts of MQS fields to allow them to be utilized by POINTER. “This presents a significant difference to how remote wave-based position sensing works and performs.”
The POINTER system operates in three components:
- Transmitter: This expertise based mostly exterior at incident command generates the MQS fields that geolocate the responders. Complex sensors and algorithms clear up for place and orientation, monitoring responders to the exact ground they’re situated on from up to 70 meters away.
- Receiver: As they enter a burning construction, firefighters put on a tool, at the moment the measurement of a smartphone however that in the end will likely be even smaller, that’s wirelessly linked to the transmitter. MQS fields ping the receivers on every responder and ship knowledge again to command.
- Base Station: A laptop computer laptop situated at incident command homes a visualization element that exhibits the responders in actual time, mentioning whether or not the particular person remains to be, transferring, or down inside the construction and informing whether or not intervention could also be wanted.
S&T’s First Responder Resource Group, an advisory physique of responders from throughout the nation, expressed that this sort of expertise is a prime precedence as a result of of the lives it’ll save. Because responder enter is so important, S&T has labored hand-in-hand with them from the begin to construct this method to their specs. Since improvement started, POINTER has advanced from a expertise that might monitor first responders to inside three meters of accuracy to now finding them inside centimeters of their precise place.
S&T, NASA JPL, and trade companion Balboa Geolocation Inc. proceed to work carefully with these and different first responders from throughout the nation to operationally check POINTER. Most lately, successful tests of POINTER technology have been carried out in a 5-level, 8,000 sq. foot construction with very promising outcomes.
“The success of these tests signals the first step towards commercial availability in 2022,” added Price.
Throughout 2021, S&T, NASA JPL and first responders will proceed testing POINTER in further simulated response environments, together with rural 2- to 3-story homes, row properties and city homes, and warehouses. By 12 months’s finish, the objective is to put POINTER prototypes in the fingers of departments in cities throughout the nation (like Worcester) that may validate its accuracy in their very own coaching and operational environments.
“I’m sure I speak for the entire Worcester Fire Department when I say that we are extremely excited to begin the testing process with the development team and DHS,” stated Chief Lavoie. “It is my hope that we have finally arrived with a system that works in all settings so that no fire departments will have to suffer the same losses that we experienced.”
