World is plagued by Accidents.

Need an alert for the driver.

Checking the speed of the car is important.

High speeds leads to accidents.

1 person dies every 6 minutes, 10 are injured in the same time frame.India's share of global car accidents is 10%6 % of the world's road accident deaths happen in India.

Bluetooth can communicate with 8 other devices simultaneously .

Hence we can check the speeds of eight cars simultaneously.

Range of communication is up to 100 meters of each other.

100 mts.

The group of eight devices is known as piconet.Piconet is a collection of Master and slaves.The frequency of 2.4 GHz is shared among all the devices in the piconet.

Master is a device which controls all the devices around it.

Slave is a device which is being controlled by a master.

Here A,B are masters and S1 to S6 are the slaves.

If the distance between two vehicle is within the 100m the Bluetooth devices get enabled.

<=100 mts.

>100 mts.

If the distance come closer within 10m the automatic braking system takes the control.

<10 mts.

After the speed of the car is reduced, the hydraulic valves decreases the pressure on the braking circuit, thus effectively decrease the braking force on the wheels.

Four main components to an automatic braking system. 1)Speed sensors 2)Pump

3)Valves 4)Controller

Short distance, low power radio operating in the unlicensed spectrum of 2.4 GHz and using a nominal antenna power of 20 dBm.At the 20 dB the range is 100 meters, meaning equipment must be Within 100 meters to each other (about 328 feet) to communicate using the Bluetooth standard.With the help of this technology we can send data to the eight devices.

A computer constantly monitors the distance between each of these cars .

When it senses that the car is getting too close it moves the hydraulic valves to increase the pressure on the braking circuit.

It effectively increasing the braking force on the wheels.

Controls the speed of the car.

In position one, the valve is open; pressure from the master cylinder is passed right through to the brake. In position two, the valve blocks the line, isolating that brake from the master cylinder.This prevents the pressure from rising further should the driver push the brake pedal harder.In position three, the valve releases some of the pressure from the brake.

The Bluetooth technology is being widely adopted by the Industry leaders.The possibility for new applications is very exciting with this Versatile technology. It provides a simple, logical answer to all the Problems-which is built a single common radio into every mobile computer.It neither do companies have to worry about WAN, nor do communication companies need to worry about building external cables.
