flashlight batteries and have little if any shock resistant capabilities. Other batteries have solder
tabs that seem to fail in the 3 to 4g range. Still others have deteriorated over time without any
warning to the flight crew.
Emerging Lifesaving Technologies uses only welded-tab batteries and our internal tests show
survivability over 500g. In addition, the specific battery chemistry lends to long shelf life, no
corrosion, and no natural decay. This battery pack has proven to provide over 110 hours of
continuous operation. The battery pack is attached to the back plate with a shock absorber
material to prevent them from rattling around during normal flight. A battery life monitor is
installed to ensure at least 36 hours of operation. This is 50% more than the minimum 24 hours
required by the FAA.
In addition, the PC board is mounted on shock absorbers and all loose wires and connections are
sealed with a potting compound to reduce failures.
Emerging Lifesaving Technologies has tested far and above the minimum requirements and all
of our units are capable of being installed in any aircraft or helicopter.
Our blade antennas are both vertically and horizontally polarized. This means that unless the
aircraft is completely up-side-down it will not be masked from satellite surveillance. Mid speed
(250 kts), and high speed (600 kts) antennas are available with altitude capabilities up to 50,000
ft.
Note: Helicopters require different G-switches due to different attitudes of flight but the basic
unit is the same.

T007 and DO-160F testing.
