INTRODUCTION ADDICTION is a chronic disorder which is a combination of genetic ,biological and social factors ex: gambling , alcohol consumption etc Addiction avoider is based on simple principle of controlling “ Brain waves” KEY TERMS: BRAIN BRAIN WAVES ADDICTION

BRAIN: ELECTROCHEMICAL ORGAN Temporal lobe produces brain waves AMYGDALA controls social sexual and other emotions Generates 10 watts of power

DIFFERENT BRAINWAVES AND ITS FREQUENCIES SNO BRAIN WAVES FREQUENCY (HZ) ASSOCIATED WITH 1 DELTA 0.5-4 Deep dreamless sleep 2. THETA 5-8 Dreams 3. ALPHA 9-14 Meditation 4. LOW BETA 15-32 Active conversation 5. HIGH BETA 32-40 stress, depression Different brainwaves with their names and the situations when it occurs.

TYPES OF ADDICTION PHYSICAL DEPENDENCY PSYCHOLOGICAL DEPENDENCY Appearance of charecteristic with drawal symptoms when drug is suddenly discontinued Antideppresants EX:cartisone,effexor This chain can be stopped by doctor intervention These are dependency of mind and lead to psychological withdrawal symptoms These are opposite to physical dependency EX:opium This chain is difficult to break

RECOVERY THERAPY To assess the severity of problems of addiction an index is developed known as ADDICTION SEVERITY INDEX based on factors-: Medical Employment Alcohol and other drug use Legal Family/social Psychiatric Medical detoxification, Ibogaine, methadone-for healing opium addiction Counseling classes

THE ADDICTION AVOIDER PRINCIPLE: It works on principle of “BINAURAL BEATS” “ A beating tone will be perceived when two tones at slightly different frequencies mixed naturally ,out of brain.” Frequency of beating tones : Range 1000-1500hz Difference <30hz

WORKING EEG SENSOR: It Senses analog brain wave and applied to the 8515 microcontroller 0.7 inch diametre in size It is a hard plastic outer disc made up of silver Chloride cap

8515 MICROCONTROLLER PIN OUT DIAGRAM OFAT90S8515 “Utilizes the AVR® RISC Architecture” 118 Powerful Instructions 32 x 8 General Purpose Working Registers Specifications: Low-power, High-speed CMOS Process Technology Fully Static Operation Power Consumption at 4 MHz, 3V, 25°C • Operating Voltages: 2.7 - 6.0V (AT90S4414 and AT90S8515) 4.0 - 6.0V (AT90S4414and AT90S8515)

AMPLIFIERS GAIN FORMULA: TOTAL GAIN = A1*A2*A3*A4 =2*10^5 A = -R2/R1,

OSCILLATORS & STEREO HEAD PHONES WEIN BRIDGE oscillator generates audio freqs below 1500 hz Two oscillators are designed with difference in frequency ranges STEREO HEAD PHONES It sends audio waves from two oscilators to the two Sides of head phones

APPLICATIONS IT avoids the addiction caused by narcotic Drugs and alchohol Simple addictions like over-eating Gambling etc A person under deep depression Can be cured To study the resonance of brain during brain diseases

FUTURE PROSPECTS MERITS: DEMERITS: Pregnant women Pace maker users The concept of binaural waves can be further researched and find out a communication with deaf and dumb people. MERITS: It is light in weight Economical(costs around Rs3000/) Head band completely touches skin DEMERITS: Pregnant women Pace maker users
