About this project

Overview

2 out of 3 police officers killed in the line of duty do not die from gunshot or stab wounds but rather from the subsequent blood loss associated with those injuries, according to The International Association of Chiefs of Police. Many of these officers lose consciousness and are unable to notify backup of their location. 

The SoLo Rescue Signal is an auditory beacon that will help identify the location of an injured officer.

In partnership with Project Triage, Nanohmics has developed an electronic rescue signal which operates like a flashlight and generates 109dB of sound. It is small, lightweight, rugged, and can easily be worn on a patrol belt. 

Now we need your help to get the SoLo Rescue Signal into the field. 

Project Triage, a non-profit organization, was founded by former Police Chief Christopher Howell in response to an incident in August 2012, where he was shot in the line of duty. Just months prior to this life-threatening incident, Chief Howell obtained trauma kits and field training for his unit. Chief Howell’s injuries would have resulted in his death had he not applied the trauma kit that he was now carrying. 

Since 2013, Project Triage has donated over 5,000 trauma kits to Police Departments and 9 officer's lives have been saved.  

In 2015, Chief Howell approached Nanohmics with an idea for a man down marker and after numerous iterations the SoLo Rescue Signal is now ready for production. To continue the amazing work Project Triage has done, we partnered with them to distribute this safety device to Police Departments across the country.

How it Works

To quickly locate the origin of a sound, humans needs to identify both the distance and direction. Our auditory system uses several cues, including time and level differences between both ears, spectral information, timing analysis, correlation analysis, and pattern matching.  

The SoLo Rescue Signal utilizes the interaural intensity and time differences to improve the speed and accuracy with which it can be located. The specially designed siren tone sweeps from a low frequency (2.75 KHz) to a high frequency (3.25 KHz) twice per second.
