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 and allow them to notify their counterparts quickly, safely, and effectively.
In conjunction with Nanohmics, Project Triage 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.
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 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 to a high frequency twice per second.
- 109dB can be heard up to 400 yards away
- Runs for 8 hours on a single CR123 battery
- Rugged housing made of machined aluminum
- Light weight – 3.2 oz. with battery
- High quality anodized surface finish
- Single on/off switch for easy operation
This product is now available on Kickstarter for purchase or donation via Project Triage.
