4. Technical description

The e-Turtle vest is provided with an electronic system incorporating an algorithm
capable of analyzing the user's movements. When abnormal movements, a fall or an
accident are detected, the system automatically triggers the airbag to inflate before
impact. In the event of an accident, the airbag inflates in 80 ms.
A second optional fork sensor (SDU), to be placed on the motorcycle, can be
associated with the vest to have a more effective protection. It detects more accidents
and it detects them faster. The sensor communicates with the vest when an abnormal
movement is detected on the motorcycle. The fork sensor is an option that is only
compatible with Helite motorcycle electronic vests.
A. IMPACTS AND DETECTED ACCIDENTS
Autonomous version (without SDU fork sensor), the system only detects accidents
from a speed above 20 km/h. Here are the possible detection cases:
- Motorcycle striking or being struck by a significant obstacle (vehicle, wall, post, etc.)
from the front, side or rear.
- Loss of control of the motorcycle (without impact on the motorcycle): Slipping on the
side or falling off the motorcycle.
When the vest is associated with the SDU fork sensor, the list of detected
accidents is extended to impacts from 0 km/h on (e.g. impact when stopped by a third
party vehicle).
The detection time is significantly faster in case of an impact against a vehicle when the
vest is used with the fork sensor.
Please note that each accident is different. Even though the Helite crash detection
system covers a large majority of potential accidents, there is always a non-zero risk of
non-triggering, especially in the following situations:
- Lack of GPS signal (tunnel, underground parking, etc.)
- Speed too low (especially when using the vest in autonomous version)
- Low-amplitude fall.
Caution: The vest sensor is sensitive to sudden body movements. Do not
intentionally execute movements that are not necessary for normal motorcycle
riding.
It is equally important to not intentionally cause shocks to the fork sensor when
your vest is on.
Both of these cases could trigger the airbag to inflate.
