Electronic Stethoscope Project Abstract

Introduction:

The project aims at designing a electronic stethoscope. We will design a circuit which same as a conventional stethoscope. The circuit is designed on a veroboard. The entire circuit runs on a 9V battery source. By using low cost electronic components like resistors, capacitors and opamps the required design is achieved.

Circuit description:

The heart beat sounds are generated will be in low frequency range of 20 t0 30 khz. So it equipment must be designed to detect these low frequency range. The opamp is made to operate low frequency ranges so the gain of the opamp will be in the range of 3.9. The high output impedance of the fet makes the resistor to operate at 12 khz, by which the capacitor allows only low frequency signals. A Butter worth low pass filter with a cutoff frequency of 103hz is produced due to gain of the resistors and by making it to pass through capacitors a sharp butterwoth response is produced. By reducing the capacitor gain values the cut off frequency gets increased to 1khz and this frequency range is used for detecting respiratory sounds.

Design:

The entire circuit is placed on a veroboad and the microphone is connected by using a shielded cable. The microphone is connected to the stethoscope by using a isolated rubber sleeve. The stethoscope head can be designed by using thick jar. The microphone must be sealed properly to avoid acoustical noise. To avoid fiction noises the microphone head must be moved while listening heart beats. Thus the stethoscope can be designed by using electronic components.

Electronic Wastage’s A Poisonous Soup of 21st Century Seminar Report

Introduction to E-wastage:

This paper mainly elaborates about wastage and harmful effects on environment E-Wastage occurs due to useless electronic equipment’s which are dumped into the soil or thrown into oceans. Some of developed countries make use of undeveloped countries for dumping their E-wastage contains led and plastic which harm the nature. so we mainly stress on the aspects to reduce E-Wastage and recycling methods  to be followed

Briefly into the E-Wastage effects and recycling methods:

All the electronic components contain led in certain percentage levels mainly the batteries contains 50% of led ,monitors contain 29% of led and other product  has the less composition of led. America has been dumping its 80% of the E-Wastege in asia. In order to control this E-Wastage company’s hare to process recyclable products .the use of led and other tonic materials are to reduced and they are to replaced by metals or recyclable materials. The alloys systems have to use for replacement of led, these alloys are to be brought in to extensive use. The availability of these alloys should be more and cost effective so that the companies prefer to use these alloy materials instead of led. the CFA project will work efficient to meet the temperature requirement of the metals because the melting point of metals is more compared to that of led.

Effects of E-Wastage:

Due to continuous dumping of E-Wastage in soil, in that soil area gets effected .in such areas the water gets polluted and that soil cannot be used for agriculture purpose if the people think of that polluted water affected with dreadful diseases .after the recycling process the left out material like plastic board and microchips and other elements are burnt due to which air gets polluted .the cycle workers the point brass has for extracting small remains of toner due to which toner clouds gets formed in such areas. It has a serious effect on the respiratory system of the human beings. Many electronic ports are compromised of tiny amount of gold which is extracted by process called acidic stripping while performing this process several tonic gases are released into environment .the remaining wastage obtained after this process are thrown into rivers affect the aquatic life and humans who use the water for various purpose .thus we can conclude that E-Wastage is serious growing problem which is to reduced by taking preventing measures.

PIC Micro controller Data Acquisition System Project Report

Introduction:

The debugging of an electrical circuit can be done by knowing the voltage , temperature and current information. By providing the data acquisition system in the power supply  we can know these values . this paper concentrates on developing a data acquition system which measures the voltage from 0 to 50v, current values up to 50 amps and finds temperature on the ambient and load.

Construction of data acquition system:

The current voltage and temperature sensors are used which gives the sensed information during the working of the circuit the sensed information from the sensors is fed to analog to digital converter, which is a 14 pin package. For monitoring the process a pic micro controller is used. From the available pic microcontroller’s we need to select the required one which has a 4adc channels and counter timer and quart. For the pic microcontroller to operate accordingly we have to provide it with the data. The internal oscillator frequency is set to 4mhz for its working. The baud rate at which the data is transmitted is 9 bits in which one bit  is used for stat or stop information and the other 8 bits are used for data information. To control the sampling rate timer is used and by polling the overflow bit are controlled. The micro chip on the pic microcontroller provides environment for compiling coding setting up and controlling programs. The flash memory of the pic can be reprogrammed by using the interface ide of usb. By using RS232 and max232 the transfer of digital data is possible in between the pc and thru registers of the microcontroller.

 Conclusions’ and Future scope:

Here the complexity of the project increases due to selection of the pic microcontroller other than a normal microcontroller. The data acquisition system can be further developed by the use of high resolution ADC converters. Here the chances of crashing occurs when the captured data is plotted on a excel sheet, which can be overcome by use of high integrated capture display programs.

E-coupled Wireless Technology Seminar Topic

Introduction to e-coupled technology:

E-coupled technology is the process by which the power gets transmitted to the electrical devices virtually without the use of chords. In this the control unit monitors the flow of power. A single power source is used for the transmission of power. By using the concept of resonance the power gets transmitted which has efficiencies greater than 98%. The power is transmitted to the devices by the authentication process.

Brief into e-coupled technology:

The dynamic control and inter operability is employed so that the power gets according to the device range, thereby reducing wastage and providing device safety. A protocol system is employed to communicate with the devices. The devices have to detect and to undergo authentication so that they can receive power according to their specified range. A parasitic metal detection is used so that the power source can run over the specified and shut down when the device do not need power. By this the power source can maintain the devices within the range and provide a higher efficiency.

Advantages:

 By using e-coupled technology the risk of shorting arcing are overcome. The usage of the interconnection system for the power transmission gets reduced. E-coupled technology allows simultaneous transmission of power to multiple users at a time. E-coupled technology is an echo friendly technology which does not cause any pollution. This technology is being successfully used in espring water purifier systems. E-coupled technology can completely eliminate the connector losses which in turn increases the efficiency.

Echo Cancellation MatLab Project Report

Introduction to echo cancellation:

To improve the voice quality of the telephone calls echo cancellation method is employed to completely eliminate the echoes occurred during transmission and reception. By using the silence suppression method the echo get cancelled from the signal. The two types of echoes which occur in telephony signals are acoustic echo and hybrid echo. In this paper we are going to look into the causes for occurring and the cancellation methods proposed by the AT&T bell labs for suppression of the echoes. DSP processors are used for the echo signal from the reappearing original signal. The echo cancellation techniques were first proposed in 1950s for cancellation of echoes occurred due to long delays in satellite communication.

Acoustic echo:

The acoustic echo occurs due to sound coning from loud speakers. The acoustic echo along with the original voice signal enters into direct path. The echo signal will have change in frequencies due to absorption and varied frequencies at different strengths. To suppress the signal the far end signal is delivered into the room by using a speaker and delayed to reassembled a near end signal. By subtracting both the signals we will obtain the echo free signal.

Hybrid echo:

Due to reflection of the electrical energy by public switched telephone networks the hybrid echoes are generated. Because PSTN allows the same frequencies to be generated so to suppress these echoes we employ full bandwidth cancellation method by which the original speech signal is reassembled.

Disadvantages:

Due to echo suppression techniques double talk gets generated by which it echo suppressor cannot detect the signal of far end speaker. Due to alternative inserting and removing loss the clipping of the signals occurs.
