2. Principles of Operation
The System consists of an Airbag Control Unit (6) with built-in sensors integrated into the
Back Protector (5) and with two external sensors positioned on the shoulders, as shown in
Figure 1.
The cluster of sensors consists of 3 tri-axial accelerometers (1 positioned on the back protec-
tor and 2 positioned on the shoulders) and 1 tri-axial gyroscope. These sensors monitor the
User's body for shocks or unexpected movements. In the event the User's body is subject to a
high and/or sudden amount of energy, the System will deploy. This may occur when the mo-
torcycle is involved in an accident, such as when the motorcycle collides with another vehicle
or object, when the rider loses control or when the rider falls off the motorcycle.
The System is equipped with a Bluetooth Low Energy (BLE) device located in the Electronic
Control Unit (16). The BLE allows the System to connect directly to a mobile phone in order to
receive important information from the System, while also permitting the users to access a
number of other functions (for further information see Section 17 "Tech-Air
important being the ability to update the System to the most recent version of the software.
To connect the System to the mobile phone via Bluetooth, remember to ac-
tivate the Bluetooth module (by turning on Bluetooth on your mobile device)
within your mobile phone's settings and make sure that you immediately
download the Tech-Air
Apple App store.
