Project on Pulse Oximeter

For patients at risk of respiratory failure, it is important to monitor the blood oxygen saturation of such individuals to ensure proper perfusion of blood in their system. Preferably this information should be received on a continuous basis. Both of these objectives can be reached via the non−invasive method of pulse oximetry. This is currently used in hospital/clinical settings, however uses wires which in effect bound an individual to an area. The purpose is to create a clinical diagnostic system which takes a few physiologically relevant signals and transmits them wirelessly to a base station.  This project specifically deals with the design of a wireless pulse oximeter for this system. By using the principle of differential light absorption and the assumption that the transmission of light through the arterial bed is influenced only by the relative concentrations of oxygenated and reduced hemoglobin and their  absorption coefficients at the two wavelengths, light intensity will decrease logarithmically according to Beer−Lambert’s law.The theory behind our device, hardware design and the experimental results of the system are presented.

Project on Wireless Drawing Device

For our final project, we want to build a wireless drawing device. The user uses a keypad or a mouse to draw on the TV through a wireless communication medium (RF - 433.92 MHz). The user should be able to move
the drawing pointer to anywhere within the four border lines. One should also be able to draw or erase images on the TV screen. In designing this project, we have two goals - a primary, which is realizable, and a secondary, which is feasible. Our realizable goal is to build a wireless keypad interface with the television. In this interface, we want the keypad to be able to draw and erase on the TV. When we accomplish our primary goal, we shall attempt to achieve our secondary goal: to build a wireless mouse having the same functionality as the keypad. Due to time constraints, we ended up only being able to complete the primary goal. We chose this project because we were inspired by wireless communication technology.

Project on Security Entrance System

Our security system is a stand alone device that allows access to registered users identified by their magnetic cards.(For this project, "access" is represented by a lit LED, showing how the system could be used to control an external locking mechanism.)The system includes features such as:
  • Multiple accounts, including Administrator accounts (which can create, modify, or delete the other accounts). The account information is stored in non-volatile EEPROM memory, so that it is maintained even if the system is reset.
  • A "lock down" of the system when someone tries to gain access by repeatedly swiping incorrect cards.
  • A 20x4 LCD display to give the user feedback on the current state (such as "Access allowed." or "try swiping the card the other way.") and to prompt administrators for commands. All messages printed to the LCD are simultaneously transmitted to an RS232 port, so that all activity can be logged by a PC.

Project On LEDZEPPELIN HARP

  We resolved to build the poor man’s laser harp, using LED emitters shining across a set of sensors that would notice when we blocked them with our hands.  It needed to play tones that sounded sweet and lovely when we needed it for ballads, and hard-edged and techno when we were feeling the dirty nerdy groove.  It needed to play several notes at once and listen to a remote control.  Most of all, it needed to have a 3.5mm jack so that someday we could live the dream, playing it in that room next to that guy, fog machines and all.

Project on Low-Cost Portable Potentiostat for Biosensing Applications

A potentiostat is an instrument used in chemical and biological tests that controls the voltage between two electrodes, working and reference, at a constant value. Chemical and biological tests are typically run in a three-electrode system, which includes the aforementioned working and reference electrode as well as a counter electrode. These systems are used to test the electrical activity of certain compounds or microbes, where the electrode acts as either the electron acceptor or electron donor. By monitoring the current and plotting the data against either time (chronoamperometry) or potential (voltammetry), information can be obtained as to the electrochemical activity of chemical compounds and/or microbes. In this project, we will present a design for this potentiostat using the ATMega644, an external digital-to-analog converter (DAC), and a series of operational amplifiers (op-amps). We will utilize the serial peripheral interface (SPI) to communicate between the microcontroller and DAC, the op-amps to process the signal from the DAC and apply a potential to the electrochemical cell, and the internal analog-to-digital converter (ADC) to record the current at the working electrode.

Project On Handheld Ultrasonic Rangefinder

Our ultrasonic rangefinder is capable of allowing the user to determine his or her distance from an object or wall.
When deciding on what type of project to design and construct, we decided that we wanted to create something that would have some practical use in life. Many groups in the past created video games, but we wanted to be different. We considered issues such as safety, user interface, and ease of use, and came up with the idea of making an ultrasonic rangefinder. A rangefinder can be used in various applications such as a measuring device or an obstacle detection device.

Project On Intelligent Wireless Pedometer

We have built an intelligent, wearable pedometer. This wireless pedometer can calculate many useful statistics such as the number of steps a user has taken, the distance and the speed the person has walked/run, as well as the number of calories the person has burned. This information is wireless transmitted to the base-station, and it is displayed on the PC in a useful manner. This project is in collaboration with the Paramedics Project with John Belina.Traditionally, pedometers only measure the number of steps a user has taken. Recently, more advanced pedometers include GPS units to calculate the distance a person has traveled, but using GPS substantially increase the cost of the product. Our project uses a low-cost accelerometer to determine the distance, speed, number of steps taken, and calories burned of a user instead.

Project on digital stethoscope

Our project is a digital stethoscope that displays your heartbeat on any television. It also calculates beats per
minute and alerts you if your rate falls out of a specified range.
At the highest level, the design of our project centers around an acquisition circuit, data processing in two
MCUs, and the output on a TV screen. The first part of the stethoscope is the acquisition unit, which consists of
an actual stethoscope mated with a microphone, and an amplifier circuit. The microphone captures the audible
signal from the body that is acoustically amplified by the stethoscope. After that, we bias and set the gain of the
signal using an operational amplifier so that the ADC on the MCU will be able to pick up the signal. The
analog data will be independently sampled by the two MCUs at a rate appropriate for display on the TV (CPU1) and a rate sufficient to capture the appropriate characteristics of the signal for beat detection (CPU2). CPU2, uses a moving threshold scheme to detect the actual heartbeats, and from that derive the heart rate. Then the signal is blasted to the TV, which also displays pertinent data, such as beats per minute. Additional information is displayed on the HyperTerm. If applicable, a buzzer will sound if your heart rate falls out of a specified range.

Project on Smart House power System


This project implements a smart algorithm in order to power a house with a photovoltaic, batteries or the power grid.  For this project, we worked closely with a research team whose goal is to power a home with minimal power from the power grid.  In order to form this smart home, we needed to monitor the voltage and current flow from each of the sources (photovoltaic, batteries, and the grid) and the home.  We implemented these current and voltage monitors.  The next step was to come up with an algorithm that would determine what source should be powering the house and when the battery should be charged.  The final step was to send out data to a home display module so that the data can be analyzed.

Project On Robotic Car Traction Control

Robotic vehicles are becoming increasingly complex and often need high levels of movement control. Specifically, when the wheels of a vehicle begin to slip, it is optimal to adjust their speed so that the vehicle moves towards its intended direction. Applications include vehicles traveling over rough terrain, exploratory robots, and remote controlled cars. The purpose of our project is to design and implement a four wheel drive robot that monitors the rotational velocity of each wheel and limits the amount of slip when the vehicle is accelerating.

Analysis of Frequency Response of Synchronous Machines Using the Magnitude Data

Over the past two decades, frequency response tests have become widely accepted as an alternative for determination of synchronous machine parameters. As a machine equivalent circuits move towards the high order models, designers need to analysis the performance and characteristics of the frequency response tests data. A major benefit of frequency response tests allows a more accurate modelling for the direct and quadrature axis. The normal approach is to use numerical curve-fitting techniques to match the measured data with the initial estimates time constants.
Due to the difficulty of estimating the higher order models, this thesis project is undertaken to design and implement the time constant extraction using an analytical method. This task can be divided into two steps: Firstly, the research into current methods used for determining the both axes equivalent circuit parameters. Secondly, development of the mathematical model was to be performed using theoretical analysis and then implement the design into the simulation program using the MATLAB software. The design program will only focus on the magnitude data of the step response. This program did not require an intimate understanding of the system order to be develop but utilized only the step response of the system.

Project on Ultrasonic Haptic Vision System

The ultrasonic haptic vision system enables a person to navigate hallways and around large objects without sight, through the use of an ultrasonic rangefinder that haptically interfaces with the user via tiny vibrating motors mounted on the user’s head. The idea behind this project was to construct a sixth sensory system that interacts with the body in an intuitive and user friendly fashion and enables the user to navigate without vision. We also implemented RF transmission in order to provide feedback to a program running on the computer to keep track of the sensory data obtained from the mobile user mounted sensor system. This enabled the person sitting at the computer to observe all the distances between the surrounding obstacles and the user wearing the hat. The rangefinder rotated on a motor atop the hardhat in order to take the sensory data at discrete points around the user. The hat and required hardware is all battery powered so that it is totally mobile and can be used as intended, so that movement is not restricted by the length of wires.

A simple Seismometer/Earthquake detector Project

Most earthquake detectors use a heavy weight attached to a coil moving inside a magnetic field. Earth movement will cause the ground and attached magnet to move. The suspended weight and coil tend to stay stationary and hence a signal is generated. Elaborate electronic filters and damping needs to be employed to get a meaningful signal.
My project avoids some of these problems by the use of ready made detectors with a low impedance and their own built in damping.

Project on Fire Fighting Robot

Trinity College hosts an annual Robot Fire-Fighting contest drawing participants from around the world. The contestants vary in age, skill level, and experience, ranging from middle school students, college students, professors and all other robot enthusiasts. The purpose of this contest is to simulate the real-world operation of an autonomous robot providing a fire protection function in a house. The situation being simulated is a robot inside a home responding to a smoke detector going off by searching the house for a fire and putting it out as fast as possible. The contest is used as an educational tool while simultaneously promoting advancements in the field of robotics. This robot will first be activated by a smoke alarm signal, which then will proceed throughout the mock household and search for a flame. Upon finding the flame, the robot will extinguish it by actuating a pressurized CO2 cartridge. Once the flame is out, the robot will return to its original starting position in the quickest amount of time possible. There is no weight restriction for this robot, but in order to maximize its speed and performance the robot will be light and small in size.

Project on SINGLE PHASE POWER FACTOR CORRECTION CIRCUIT WITH WIDE OUTPUT VOLTAGE RANGE

The conventional power factor correction circuit has a fixed output voltage. However, in some applications, a PFC circuit with a wide output voltage range is needed. A single phase power factor correction circuit with wide output voltage range is developed in this work. After a comparison of two main power stage candidates (Buck+Boost and Sepic) in terms of efficiency, complexity, cost and device rating, the buck+boost converter is employed as the variable output PFC power stage. From the loss analysis, this topology has a high
efficiency from light load to heavy load. The control system of the variable output PFC circuit is analyzed and designed. Charge average current sensing scheme has been adopted to sense the input current. The problem
of high input harmonic currents at low output voltage is discussed. It is found that the current loop gain and cross over frequency will change greatly when the output voltage changes. To solve this problem, an automatic gain control scheme is proposed and a detailed circuit is designed and added to the current loop. A modified input current sensing scheme is presented to overcome the problem of an insufficient phase margin of the PFC circuit near the maximum output voltage. The charge average current sensing circuit will be bypassed automatically by a logical circuit when the output voltage is higher than the peak line voltage. Instead, a resistor is used to
sense the input current at that condition. Therefore, the phase delay caused by the charge average current sensing circuit is avoided.

Engineeering Ebook: On how to develop a small hydro site

The objective of a hydro power scheme is to convert the potential energy of a mass of water, flowing in a stream with a certain fall (termed the “head”), into electric energy at the lower end of the scheme, where the powerhouse is located. The power of the scheme is proportional to the flow and to the head. Medium and high head schemes use weirs to divert water to the intake, from where it is conveyed to the turbines, via a pressure pipe or penstock. Penstocks are expensive and consequently this design is usually uneconomic. A small hydropower scheme cannot afford a large reservoir to operate the plant when it is most convenient; the cost of a relatively large dam and its hydraulic appurtenances would be too high to make it economically viable. But if the reservoir has already been built for other purposes – flood control, irrigation network, water abstraction for a big city, recreation area.

Project on Simple Digital Heart Rate Monitor

The aim of this project is to implement an ECG and Digital Heart Rate counter. The main challenges include amplifying the desired weak signal in the presence of noise from other muscles and electrical sources. A display of the heart rate will be obtained by measuring the time between signal peaks and then calculating the frequency of the peaks in units of beats per minute.
The device is most useful if it is portable. This requires a battery to be able to power all of the necessary components as well as the power output of the battery to be regulated.Our implementation of the heart monitor involves low cost amplifier and filter components coupled with a sophisticated microcontroller and LCD screen.
Results were successful for the amplifier filter stage of the implementation with an ECG successfully detected and recorded but variability of the voltage points complicated the calculation and display of the actual rate.

Project On Bluetooth Based Location Estimation for Mobile Applications

Many applications nowadays require location based services to ful ll their intended functionality. There already exist localization techniques, such as GPS, that function in outdoor schemes. Yet, these techniques are not suitable for indoor scenarios where the line of sight component of the wireless signal is blocked. We propose to design a system that tackles this problem and provides the indoor location based services. Moreover, since the user's location is not xed, wired technologies can not be utilized, therefore wireless technologies should be exploited. Among these technologies, Bluetooth appears to be the best candidate because it operates at lower
power and cost and provides better accuracy. Through location awareness capability, the proposed system provides the user with a service relative to his location.
We propose to exploit the available advances of Bluetooth technology to design a solution to the aforementioned problem. The proposed solution targets mobile devices, that are within the reach of most people, such as mobile phones, personal digital assistance (PDAs), laptops, tablet PCs.

Project Title: DEVELOPMENT OF AN EFFICIENT SOLAR POWERED UNMANNED AERIAL VEHICLE WITH AN ONBOARD SOLAR TRACKER

The scope of electric powered unmanned aerial vehicle (UAV) missions is primarily constrained by the relatively low flight endurance that is characteristic of electric powered UAVs. The purpose in utilizing solar energy to power UAVs is to increase UAV endurance capabilities and ultimately achieve indefinite sustained flight. Traditional solar powered UAVs are designed to statically fix the photovoltaic (PV) cells on the top surface of the wing, keeping the cells virtually parallel to the earth’s horizontal plane during normal flight. This puts significant restrictions on both where and what time of year a solar powered UAV is able to capture enough energy from the sun for the PV cells to be advantageous.

Power electronics has already found an important place in modern technology and has revolutionized control of power and energy. As the voltage and current ratings and switching characteristics of power semiconductor devices keep improving, the range of applications continues to expand in areas such as lamp controls, power supplies to motion control, factory automation, transportation, energy storage, multi-megawatt industrial drives, and electric power transmission and distribution. The greater efficiency and tighter control features of power electronics are becoming attractive for applications in motion control by replacing the earlier electro-mechanical and electronic systems. Applications in power transmission include high-voltage dc (VHDC) converter stations, flexible ac transmission system (FACTS), and static-var compensators. In power distribution these include dc-to-ac conversion, dynamic filters, frequency conversion, and Custom Power System.

Engineering Ebook: Antenna Engineering Handbook, Fourth Edition

Needless to say, the commercial mobile communications industry has been the catalyst for the recent explosive growth in antenna design needs. Certainly, the past decade has seen an extensive use of antennas by the public for cellular, GPS, satellite, wireless LAN for computers (WiFi), Bluetooth technology, Radio Frequency ID (RFID) devices, WiMAX, and so on.Antennas are key components of any wireless communication system.1,2 They are the devices that allow for the transfer of a signal (in a wired system) to waves that, in turn, propagate through space and can be received by another antenna.

Engineering Ebook: Schaum's Outline of Digital Principles, Third Edition

The topics outlined in this book were carefully selected to coincide with courses taught at the upper high school, vocational-Iechnical school, technical college, and beginning collcge level. Several of the most widely used textbooks in digital electronics were analyzed. The topics and problems included in this Schaum’s Outline reflect those encountered in standard textbooks. Several microprocessor/ microcomputer-related topics have been included, reflecting the current practice of teaching a microprocessor course after or with digital electronics. A chapter detailing the characteristics of TTL and CMOS devices along with several interfacing topics has been added. Other display technologies such as liquid-crystal displays (LCDs) and vacuum fluorescent (VF) displays have been given expanded coverage. The chapter on microcomputer memory has been revised with added coverage of hard and optical disks. Sections on programmable logic arrays (PLA), magnitude comparators, demultiplexers, and Schmitt trigger devices.

Engineering Ebook: Practical Transformer Handbook

This book takes a somewhat different tack; it deals largely with transformers more relevant to electronic technology, control techniques, instrumentation, and to unusual implementations of transformers and transformer-like devices. In sodoing, the author feels that the highest usefulness will ensue from emphasis on the practical aspects of such transformers and their unique applications. For, if properly done, those readers wishing to probe further will have been guided along appropriate paths to extended investigation. The underlying objective is to stimulate the creativity of engineers, hobbyists, experimenters and inventors, rather than to provide a conventional classroom-like text. It is to be hoped that a readable and interesting exposition of the topic will help dispel much of the prevalent notion that transformers are mundane devices of a mature technology with little prospect of further evolutionary progress. To this end, it should be easy to show that the traditional treatment of transformers,
althogh providing a solid academic-foundation, tends to confine the modern practitioner to a bygone era.

Engineering Ebooks: Power Generation Technologies

This book is primarily about the ways of generating electricity. It does not cover the means of transporting electricity and delivering it to those who wish to use it. Nor does it treat, except obliquely, the political issues that attach themselves to electricity supply. What it does attempt, is to provide an explanation of all the myriad ways that man has devised to produce this most elusive of energy forms. The book is divided into chapters with one chapter devoted to each type of electricity generation. The explanations provided are thorough and
technical where necessary but do not resort to overly technical language where this can be avoided. Readers, who are seeking a full analysis of the thermodynamics of the heat engine, or the differential equations for solving the problem of turbine flow, will need to look elsewhere.
