Using Path Defender

Contact!

The motherboard is still asleep, saving your battery's energy! The LEDs remain shut down.

Turn signal on!

The bulb works as usual, run by the turn signal module of the motorcycle. The turn signal LED are turned on and off along with the bulb, temporarily disconnected from Path Defender.
 
Start engine!

The motherboard wakes up! The white LEDs inside the front turn signals light up, shining with a steady light or flashing slowly as the engine idles, depending on the chosen connection on the motherboard wiring.
The LEDs switch automatically to maximum or minimum light intensity depending on ambient light conditions. At dark, the light intensity is considerably lowered thanks to the Path Defender light sensor you've mounted on the front of your bike. This avoids disturbing or even glaring other drivers at dusk or at night.
Path Defender allows to simply choose the way the motherboard drives the LEDs: wind the antenna one turn around one spark plug wire to select the flashing mode, or just leave the antenna under the seat if you prefer the steady lighting mode.

A) The antenna wire is still under the seat
The LEDs are in steady mode. The bike's turn signals are performing as two extra light sources, enlarging the bike's light print.

Advantages:
   1. Improved conspicuity: three light sources instead of one (the headlight), stronger total luminosity of the bike.
   2. The distance between the turn signals improve by a factor of 4 (ratio turn signals/headlight width) the perception of the distance to the bike.
   3. The bike's direction changes are easier to perceive because the Path Defender optic produce narrow light beams from the LEDs, restrained to a smaller sector on the bike's axis.
   4. The LEDs cold light is slightly different from the headlight's, allowing other drivers to spot the bike more easily among other vehicles riding with their headlights on.

B) The antenn wire is wound one turn around one spark plug wire
The motherboard uses the signal from the antenna wire to compute a flashing frequency used to drive the LEDs in each front turn signal.

The LEDs flash at a frequency depending on the engine revs, starting at 1 Hz when the engine is idling and going up to 10 Hz at the maximum engine revs reached since the first pulse on the chosen spark plug wire. This value is reset at each engine start.

Advantages:
1) The most informative indication on the engine revs, either at stabilized speed or during an acceleration/slowing down.
2) Other drivers see instantly if the LEDs are flashing at high frequency, instinctively associated which speed, and whether the flash is speeding up or slowing down, which is intuitively related to a speed increase or decrease.
2) The flash catches the eye more effectively than a steady light. Path Defender is stimulating other drivers' attention; they reach instinctively a higher awareness level.

All Path Defender indications are provided permanently, and in particular in the dangerous situations accounting for 75% of bike accidents (ratio in France).

Shut the engine off!

The motherboard checks for a few seconds the engine really has stopped, turns the LEDs off and switches automatically to low consumption mode, saving your battery.
