3. WHAT ARE EMBEDDED SYSTEMS? An embedded system is any device controlled by instructions stored on a chip. These devices are usually controlled by a micro processor that executes the instructions stored on a read only memory(ROM) chip.

4. IN THE DRIVING SEAT There are several tasks in which real time OSs beat their desktop counterparts hands-down. A common application of embedded systems in the real world is in automobiles because these systems are cheap, efficient and problem free. Almost every car that rolls off the production line these days makes use of embedded technology in one form or the other.

5. THE DOCTOR WILL SEE YOU NOW Imagine a time when body transplants like cardiac pacemakers will be able to monitor and manage themselves remotely. These systems will be so compact that the patient wouldn’t even be aware that they are embedded in his body.

6. WIRED WEARABLES A mobile phone in the form of a ring or an ear ring? What about cool sunglasses with streaming video displays built into them? All these can soon be a reality. Embedded systems have a small foot print and consume very little power which makes them ideal for wearable computing applications. The minimal system requirements of these devices ensure that the hardware is almost microscopic.

7. DON’T KEEP YOUR EYES ON THE ROAD Embedded systems can also make driverless vehicle control a reality. Major automobile manufacturers are already engaged in work on these concepts. One such technology is Adaptive Cruise Control (ACC).

8. THE WORKING PRINCIPLE OF ADAPTIVE CRUISE CONTROL Higher Pitch Sound In this case the vehicle is speeding towards the stationary listener. The distance between the listener and the car is decreasing. Then the listener will hear a higher pitch sound from the car, which means the frequency of sound, is increased.

9. Lower pitch sound In this case the vehicle is moving away from the listener. The distance between and the car is increasing. Then the listener will hear a lower pitch sound from the car, which means the frequency of sound, is decreased. So that is the Doppler Effect in case of sound waves.

10. ABOUT THE BEAUTY OF ADAPTIVE CRUISE CONTROL As the driver in the next lane swerves in front of you, you feel that gas back off and the brakes grab in the car you’ re driving- a Mercedes Benz S-class luxury vehicle, the first passenger car equipped with a technology called adaptive cruise control. The technology makes these adjustments even though you haven’t touched the brake or gas pedal.

11. CONCLUSION Most of the microprocessors in the world are not in pcs, they are embedded in devices which control traffic for highways, airspace, railway tracks, and shipping lanes to manufacturing systems with robots. An embedded system is any device controlled by instructions stored on a chip.
