Rushikesh Yeldari

This document outlines a project to monitor ECG signals on an Android smartphone. It includes an introduction, sections on what an ECG is and why Android was chosen, a block diagram of the system components, and a conclusion. The system will use an ECG sensor, amplifier, ADC, heart rate sensor, microcontroller, serial interface, and Bluetooth module to monitor and analyze a patient's heart condition through ECG electrodes and display a graph on an Android phone. The goals are to implement ECG monitoring outside of a hospital setting using wearable, robust hardware that can be used in remote areas.

EKG Project Oral Presentation

Abdiqani Sidow

The document describes an ECG project being developed by a student group. The project aims to create an ECG device that outputs heartbeat waveforms to an oscilloscope and displays pulses on an LCD screen. The group has developed analog filtering, amplification, and power subsystems, as well as a digital subsystem to process signals and drive the LCD display. While integration testing is still needed, subsystems are functioning individually according to specifications. The group plans to complete PCB design and begin enclosure design before the deadline.

soldier tracking and health monitoring system

Joshpin Bala.B

This document describes a project to track soldiers and monitor their health status during war using sensors, GPS, and GSM. The system includes sensors to monitor a soldier's pulse rate and temperature, along with a GPS module to track location. If the soldier's pulse drops below 60 or their coordinates exceed a certain range, the system will automatically make an emergency call through the GSM module to alert others. The goal is to allow army personnel to plan strategies based on real-time soldier location and health data. The system uses an ARM7 microcontroller to process data from the sensors and GPS and communicate through GSM when needed.

akbarsaleemtakkasila

This document describes a collision avoidance system using ultrasonic sensors and a microcontroller. The system works by transmitting ultrasonic pulses and measuring the time it takes for the echo to return, allowing it to calculate the distance to any obstacles. If an obstacle gets too close, the system can activate emergency braking. It also monitors vehicle speed and alerts the driver if the speed limit is exceeded. The system aims to help avoid accidents by detecting obstacles and enforcing speed limits.

Automatic solider tracking & health monitoring system

ijaranjani

This document presents a project report on an Automatic Soldier Tracking and Health Monitoring System. The proposed system uses sensors to monitor a soldier's heart rate and body temperature. If the soldier is injured, their vital signs would change. The system would detect this and use a GSM modem to send an alert message with the soldier's location from the GPS modem to a base station. This would help provide medical assistance. The system has advantages like security, reliability, and ability to remotely monitor a soldier's health and location. It could help defense forces better help injured soldiers in need of medical attention.

Sensor network based oil well health monitoring and intelligent control

sudhakar5472

The document proposes a sensor network-based system to monitor oil wells. It describes existing manual monitoring systems that are inefficient. The proposed system uses sensors to measure oil well parameters like temperature and pressure. A Zigbee network transmits these measurements to an intermediate section, where an ARM7 microcontroller analyzes the data and alerts a control center via GSM if abnormalities arise. The system aims to reduce power consumption, facilitate remote monitoring, and allow timely repairs, improving over manual methods.

IRJET- Health Monitoring System Based on GSM

IRJET Journal

This document describes a health monitoring system based on GSM technology that can monitor a patient's heart rate and temperature remotely. The system uses an 8051 microcontroller connected to a heart rate sensor, temperature sensor and GSM modem to measure the vital signs and transmit the data via SMS messages. If abnormal readings are detected for heart rate or temperature, SMS alerts would be sent to both the patient's doctor and relatives. This remote health monitoring system aims to reduce hospital costs by allowing for continuous at-home monitoring of patients after discharge from the hospital.

Novel Rear End Collision & Accident Avoidance System With Dynamic Speed Governor

Dilip V Reddy

The seminar discusses a novel rear end collision avoidance system using an ultrasonic sensor and microcontroller-based dynamic speed governor that can transmit the speed limit of a vehicle using RF to approaching vehicles. The system works by using an ultrasonic sensor to detect obstacles, a microcontroller to analyze transmitted data and control speed, and an RF transmitter to send the speed limit to other vehicles to help avoid accidents. The proposed system aims to increase road safety through dynamic speed control that is flexible and can be adapted using software changes to the microcontroller.

Rajdeep Limbu

This document describes a GPS-based soldier tracking and health monitoring system. It consists of two main parts: a portable soldier unit and a monitoring center. The soldier unit collects the soldier's location, temperature, and heart rate using a GPS receiver, temperature sensor, and heart rate sensor. This health and location data is sent via GSM to the monitoring center. The monitoring center uses this data to track the soldier's position and health status in real-time. The system aims to allow the army to monitor soldiers' well-being and location during combat to improve safety and coordinate responses if needed. The document provides details on the various sensors, microcontrollers, and communication components used to create this soldier tracking and health monitoring system.

Vibration Switches and Monitors

controlspecialties1

Vibration switches and monitors by Robertshaw can minimize production shutdowns and repair costs by measuring vibration in machines. They sum individual acceleration measurements to determine the total destructive force acting on equipment. This enables proactive maintenance to avoid costly downtime and repairs. Vibration monitoring provides early warnings before failures occur and protects unattended machinery. It also allows for predictive maintenance and reduced damage severity through trend analysis of vibration levels.

Interim Presentation

thusithagh

This document outlines a proposed driver sleepiness detection system. It discusses human sleep, the dangers of sleepy driving, and different methods for avoiding sleepy driving including awakening systems. The proposed system would use a sensor device on the steering wheel to monitor force and send data to a PC application, which would analyze the data using neural networks to detect if the driver is falling asleep and raise an alarm if needed. The system is intended as a concept that would not actually be tested in real vehicles.

GPS And IoT Based Soldier Tracking & Health Indication System

IRJET Journal

This document summarizes a research paper that proposes a GPS and IoT-based system to track soldiers and monitor their health. The system uses biomedical sensors attached to soldiers to measure vital signs like temperature and heart rate. GPS is used to track soldier locations in real-time. The data is transmitted via GSM modules to a base station where the soldier locations are displayed on a map and their health status is monitored. The system aims to improve soldier safety and aid in mission coordination by allowing commanders to track soldier movements and respond quickly if health issues arise.

GPS Based Soldier Tracking and Health Monitoring

IRJET Journal

1) The document describes a GPS and sensor-based system to track the location and health of soldiers. It measures soldiers' heart rate, body temperature and other vital signs using sensors and transmits the data via GSM to army control rooms. 2) If a soldier's pulse stops, indicating death, the system detects the change and sends the soldier's last known location to army bases to aid rescue operations and strategy planning. 3) The system aims to allow soldiers to communicate their location and status to commanders, and receive help in emergencies, to enhance safety during military operations.
