"V-Buzz" advanced Safety Helmet

The safety helmet is designed by my intelligence bo'on srey Na ( sister Na) and her groupmates. Although the helmet looks like a toy to me, it is very useful and safe for motorcyclists for various reasons. She promised that she will redesign a better outlook when she is free from school. It took me a long times to ask for her permission to pose in here...hehee.


below is her description on how it works:
For Safety Part,
- The main function of this helmet is to increase the level of safety to the motocyclists,esp to sleepy riders. However beside safety we also look into the energy conversation n rider comfort to enhance the safety we equippped this helmet with 3 vibrators (placed inside the helmet),one buzzer,n nit kit.The vibrators work in such a way that once the rider bend his/her head down to certain degree(as he/she start to feel sleepy) it will vibrate.If the rider still not awake n fall asleep n bend his/her to lower lever then the buzzer will be on together with the vibrators.Once the rider is back to normal position the system will be off.However, if the rider wants to bend the head for other purpose,he/she can always switch off the system b4 bending as the switch is placed outside more than that our switch is ajustable so that different users can adjust to their own level of head bending.On the other hand, the additional nit kit is used to enhance the visiblity of the rider at nit.we have glow in the dark which will shine in the dark, the reflector which shine as it is flash by the light of other road user, emergency rear light bubls will be on in the dark n quick motion (like braking).

For Energy Part:
- We use the windcharger as the power supply to our helmet.This windcharger is used to convert the mechanical energy to electricity.It is used similar concept to wind turbine though to certain wind speed the fan attaching to the motor will spin.As the fan spin the motor will produce the electricity, we connect the other side of motor to charging circuit, which function as the charging controler. The output of this circuit is connected to the rechargable batterOnce the voltage of the batter drop below the preset value (set by engineers), then this circuit will let the power flow from the motor to the batter. But, if the voltage of the batter is reach beyonce the preset value, the circuit will disconnect the motor n the batter n the charging is stop.This is to prevent the overcharging.

For Comforty Part:
- We have replace the padding of the helmet by a better material, which can absorb more sweat andn can be easily taken out for washing purpose.In addition to that we also add the activated carbon which is good at absorbing odor. This will help the rider to get rid of odor problem.
