The circuit described here can be used to switch up to nine appliances. There should be a parallel connection maintained between the telephone lines and the circuit. The DTMF signals on telephone instrument are used as control signals. The circuit consists of DTMF to BCD converter apart form demultiplexer and flip flops. The digit O in the DTMS mode is used to toggle between the appliance mode and the normal telephone operation mode. While being used for the normal conversation,the telephone could be used to switch ON or OFF appliances.

Applications :
Classification of two dimensional ,overlapping, Gaussian distributed pattern. The pattern belonging to class 1 and class 2, which follow Gausian distribution and are overlapping in nature can be classified using LMS algorithm. The optimum efficiency is 81.51%,

The other applications of neural classifiers are :

1. Spike (seizure) identification in EEG
2. Speech recognition
3. Hand written and printed character recognition

Working Principle:
In this experiment, a blower, a heater, fluized bed and themlometers are used. Blower, having a motor of 0.5 H.P. & 2880 rpm, a fan with 6 blades, is used to blow air to the heater with the power of 2 KW is used to heat the air blown by blower. Fluidized bed of height 175 mm is used with a sieve plate and perforated plate is used and feed is fed here alone. An outlet has been provided for hot air passage through the , fluidization bed.

Free flowing solid of known quantity (0.5 -3 kg) with known moisture content is fed. Blower and heater are put on and waited for some time to get a temp., of 75 -85 degrees C in the fluidized bed. After 10 minutes product is removed, this has moisture content of about .5 - 85 degrees C in a the fluided bed. After 10 minutes product is removed, this has moisture content of about 0.5 -0.8 %. Experiment can be repeated.

The project attempts to control a few functions of the computer using the T. V. remote The circuit consists of the IC TSOP1738, which works in the frequency range of 30-80 kHZ .It needs only a 5 V- supply voltage and draws a current of less than 2 mA. Thus ,it is be powered directly from the serial interface.

The circuit also makes use of a 78L05 voltage regulator IC. The supply voltage is taken from the DTR and RTS outputs of the RS232 interface, which are connected together via the isolating diodes. A voltage of around 10 V is activated here using a program running on the PC.

If the IR receiver IC receives an IR signal modulated at 36 KHz, it produces an output signal on its middle pin with an active -low level. These output pulses are connected directly to the CTS lead, where must be decoded using software. A supplementary pull-up resistor is necessary here, since the CTS lead has a relatively low input resistance. The signal is also inverted by a transistor stage and applied to the RxD Input of the serial Interface.

Features
1. High operating range of 10 meters.

3. Any RC5 coded Television Remote can be used.
4. Does not require external power supply.
