mobile controlled robo for face deetection

An autonomous mobile robot with a face detection system should be
able to find human faces. The robot is controlled through a mobile phone any
where in the world .But, what‟s more useful about out MOBILE CONTROL
ROBOT USED TO FACE DETECTION is that they can find whether human are come across the restricted area.

FOR FURTHER DETAILS
While we make call to the robot it will be in auto pick up mode .we can
control the robot after the call attended .The values are feed to the
microcontroller and they can be processed. Then robot is controlled through
far away distance with another mobile the controls are front, back, right turn
left turn ,and camera rotated with 360 degrees.
The live video is capture through a web cam .video is converted into 12
frames per second after conversion each frame is compare with the predefined
algorithms mat lab for face detection system if any human faces is detected a
marking the detected face is show on system monitor.

OP-AMP Circuits

What exactly is an OPerational AMPlifier?
Let's define what that component is and look at the parameters of this amazing device. An operational amplifier IC is a solid-state integrated circuit that uses external feedback to control its functions. It is one of the most versatile devices in all of electronics. The term 'op-amp' was originally used to describe a chain of high performance dc amplifiers that was used as a basis for the analog type computers of long ago.

MORE CIRCUIT DESIGN USING OP-AMP
I have given full detials

The very high gain op-amp IC's our days uses external feedback networks to control responses. The op-amp without any external devices is called 'open-loop' mode, referring actually to the so-called 'ideal' operational amplifier with infinite open-loop gain, input resistance, bandwidth and a zero output resistance. However, in practice no op-amp can meet these ideal characteristics. And as you will see, a little later on, there is no such thing as an ideal op-amp. Since the LM741/NE741/uA741 Op-Amps are the most popular one, this tutorial is direct associated with this particular type. Nowadays the 741 is a frequency compensated device and although still widely used, the Bi-polar types are low-noise and replacing the old-style op-amps.
Shown in Fig.1 at the right are op-amp symbols as usedtoday. The one on the right is an older way of drawing it but still used in books like the ARRL (American Radio Relay Leaque) and older schematics. It is common practice to omit the power supply connections as they are implied.

MOBILE BUG

This handy, pocket-size mobile transmission detector can sense the presence of an activated
mobile phone from a distance of one and-a-half metres. So it can be used to prevent use of mobile phones in examination halls, confidential rooms, etc.


HOW DOES IR WORKS

It is also useful for detecting the use of mobile phone for spying and unauthorised video transmission. The circuit can detect both the incoming and outgoing calls, SMS and video transmission even if the mobile phone is kept in the silent mode. The moment the bug detects RF transmission signal from an activated mobile phone, it starts sounding a beep alarm and the LED blinks. The alarm continues until the signal transmission ceases. An ordinary RF detector usingtuned LC circuits is not suitable for detecting signals in the GHz frequency band used in mobile phones. The transmission frequency of mobile phones ranges from 0.9 to 3 GHz with a wavelength of 3.3 to 10 cm. So a circuit detecting gigahertz signals is required for a mobile bug.

ELECTRONICS PLAYS IN MEDICAL FIELDS

• ECG • EEG • EMG • PCG • EOG • ANIMAL CELLS
ECG
Deals with the study of electrical activity of the heart muscles. The potentials originated in the human being fibres of heart muscles are added to produce the ECG waveform. Electrocardiogram is the recorded ECG wave pattern. Heart consists of four chambers namely two auricles and two ventricles. Cardiac action potential is generated by contraction and expansion of the muscle fibres.

HOW DOES IT PLAY
EEG
Deals with the recording and study of electrical activity of brain. By means of electrodes attached to the skull of the patients , the brain waves are picked up and recorded.
Electromyography (EMG)
It is the science of recording and interpreting the electrical activity of muscle’s action potential. Recording of peripheral nerve’s action potential is called ELECTRONEUROGRAPHY
Electrooculography (EOG)
It is a technique for measuring the resting potential of the retina.
the resulting signal is called the electrooculogram. The main applications are in ophthalmological diagnosis and in recording eye movements.
BIO-CHEMICAL & NON-ELECTRICAL
PARAMETER MEASUREMENT
RADIOLOGICAL EQUIPMENTS
WHAT IS ENDOSCOPY?
An endoscope is a medical device consisting of a camera mounted on a flexible tube. Small instruments can be used to take samples of suspicious tissues through the endoscope. In gastrointestinal (digestive tract) endoscopy, this device is inserted through the mouth or anus. For other areas, small incisions are made.
WHAT IS LASER?
Laser is an acronym for Light Amplification by Stimulated Emission of Radiation. Laser beam consists of high intense radiation in unique direction without spreading of its energy in other directions.

Wiper Circuits for Transports

A popular modification for early Sprites and Midgets is to replace the single speed wiper motor with a dual speed motor from a later model car. While it's relatively easy to wire up a switch for the two speeds, getting the wiper motor to auto park when the switch is turned off can be a little more tricky.


HOW DOES IT WORK

Flicking the toggle switch to the first position (slow operation), power is applied to the relay, closing the contact and supplying power to pin 5 on the wiper motor (via pin 87 and 30 on the relay). The Auto Park connection on the Wiper Motor (pin 2) is not connected to anything while the relay is energized.
Flicking the toggle switch to the second position (fast operation), power is supplied directly to pin 3 on the Wiper Motor. At this point you might expect the relay to turn off, but in fact the relay remains turned on by current leaking back out of pin 5 (slow) of the wiper motor (via pin 30 and 87 of the relay). The Auto Park connection on the Wiper Motor (pin 2) is not connected to anything while the relay remains energized.
Flicking the switch to off, causes the relay to turn off, this connects pin 2 of the Wiper Motor to pin 5 of the Wiper Motor (via pin 87a and 30 of the relay). What I think happens here is that power is connected to pin 4 of the Wiper Motor, this must be internally connected to pin 2 via a switch, which allows us to continue to supply power to the slow pin 5 of the motor until it reaches the park position when pin 2 turns itself off.

How to Construct a Line Follower Robot

What is line follower robot?

Find out more inside....



For my mini project, I decided to make a line-follower robot. This simple robot is designed to be able to follow a black line or white line on the ground without getting off the line too much. The robot has two sensors installed underneath the front part of the body, and two DC motors drive wheels moving forward. A circuit inside takes an input signal from two sensors and controls the speed of wheels’ rotation. The control is done in such a way that when a sensor senses a black line, the motor slows down or even stops. Then the difference of rotation speed makes it possible to make turns. For instance, in the figure on the right, if the sensor somehow senses a black line, the wheel on that side slows down and the robot will make a right turn.

Download for the design is given below
