The design of a microcontroller based pacemaker tester is presented in this paper. Both invasive and noninvasive (transthoracic) pacemakers can be tested using this device. Two test loads are provided; a 500 ohms load for testing invasive pacemakers and a 50 ohms load for testing non-invasive pacemakers. A two line LCD display is used to indicate the test parameters, test results and the test i...

A dielectric constant measurement setup has been developed to measure dielectric constant of liquids using AT89C55WD microcontroller. A modified operational amplifier based AC Schering Bridge network is used to compute capacitance and hence calculate dielectric constant of liquids. This instrument system permits recording of dielectric constant of liquids at various concentrations and temperatu...

This project is developed with aims to improve home security systems available in current market. This project claims to produce a prototype camera and global system for mobile communication (GSM) interfacing system for home security surveillance. This system uses two sensors, namely ultrasonic and passive infrared receiver (PIR). The ultrasonic sensor is used to detect movement of objects and ...

Real-time microcontrollers have been widely adopted in cyber-physical systems that require both real-time and security guarantees. Unfortunately, security is sometimes traded for real-time performance in such systems. Notably, memory isolation, which is one of the most established security features in modern computer systems, is typically not available in many real-time microcontroller systems ...

This paper presents the development of imager block to be associated in a capsule endoscopy system. Since the capsule endoscope is used to diagnose gastrointestinal diseases, the imager block must be in small size which is comfortable for the patients to swallow. In this project, a small size 1.5V button battery is used as the power supply while the voltage supply requirements for other compone...

This review paper is based on the real world applications of various microcontrollers in the field of pacemakers. The study conducted is based on various factors such as cost, power consumption, power saving, reliability, efficiency etc. These features differentiate each microcontroller from the other. The goal of this study is to study each microcontroller that are being employed in the field ...

In the present study, a portable system based on a microcontroller has been developed to classify different kinds of honeys. In order to do this classification, a Simplified Fuzzy ARTMAP network (SFA) implemented in a microcontroller has been used. Due to memory limits when working with microcontrollers, it is necessary to optimize the use of both program and data memory. Thus, a Graphical User...

Mankind has always strived to give life like qualities to its artifacts in an attempt to find substitutes for himself to carry out his orders and also to work in a hostile environment. The popular concept of a robot is of a machine that looks and works like a human being. The industry is moving from current state of automation to Robotization, to increase productivity and to deliver uniform qua...

The purpose of this paper is to acquire the remote electrical parameters like Voltage, Current and Apparent Power and send these real time values over GSM network using GSM Modem. This facilitates the remote monitoring of these parameters without any geographical constraints, since a GSM module is used. Real time power monitoring system relate generally to the field of electric energy consumpti...

Battery management system (BMS) forms a crucial system component in various applications like electric vehicles (EV), hybrid electric vehicles (HEV), uninterrupted power supplies (UPS), telecommunications and so on. The accuracy of these systems has always been a point of discussion as they generally give an error of maximum 10% considering all the parameters together. In this paper a system is...
