Pulse Amplitude Modulation

Pulse Amplitude Modulation

Today communication is the heart of the technology. Communication is achieved over a transmitter and a receiver through signals. These signals carry the information through modulation. Pulse Amplitude Modulation is one of the kinds of modulation techniques used in signal transmission. Pulse amplitude modulation is the simplest form of modulation. It is Analog to digital conversion method where the message information is encoded in the amplitude of the series of signal pulses.

Heart Attack Detection and Medical Attention Using Heart Beat Sensor

by 4 Comments

Heartbeat sensor for medical applicationsHeart attack (coronary artery disease) is one of the most common and very serious effects of aging. The cholesterol, fatty deposits, emotional stress, and drug intake lead to build spasm in blood vessel walls. As the spasm grows, less blood can flow through the arteries. As a result, the heart muscle can’t get the blood or oxygen what exactly, it needs. This can lead to a heart attack. In this article, We are developing a system which will help to decrease the death rate due to the heart attack by early heart attack detection. In our system, we will be using smart Heart Beat sensor which is easily available in the market.

GPS and GSM Based Soldier Tracking and Health Monitoring System

by 8 Comments

Nowadays, the security system of the nation depending upon the enemy’s war and so the security of the soldiers is considered as an important role in it. Concerning the safety of the soldiers, there are numerous tools to observe the health condition as well as bullets on the soldiers. In soldiers security, biosensor system gives different kinds of sensors like small physiological, Barometric and Oxygen analyzer, processing capabilities and transmission modules, and can thus enable low-cost wearable unremarkable solutions for health monitoring system. The proposed system uses GPS to track the direction of the soldier in the form of latitude and longitude values. So that direction can be found easily.

GPS and GSM Based Soldier Tracking and Health Monitoring System

Designing of this system using GPS and GSM gives a wireless system for tracking the location of the soldier and observing the heart beat rate and body temperature of the soldier. The biomedical sensors used in the proposed system are sensor and beat. The temperature sensor is used to measure the temperature of the body as well as heart beat sensor is used to measure the heartbeat rate of the soldier.

One of the most important tasks in military processes is that the Soldier, not able to interconnect with control room administrator. In addition, every organization wants to apply for certain work when they communicate over the n/w owned and worked with other organizations. Therefore, without cautious planning and coordination, one group cannot interconnect with the other groups. Present a problem faced by the soldiers are; Soldier wants to identify the location. They will not get assistance during terror situation and soldiers are not trackable

Soldier Unit

Soldier unit is placed on the soldier. This unit has four parts, namely biomedical sensor, keypad, GSM, and GPS.

Heartbeat Sensor

The Heart Beat sensor gives an easy way to study the function of the heart This sensor is used to monitor the blood through a finger. As the heart services blood through the blood vessels in the finger, the blood amount in the finger changes with respect to time. Heartbeat sensor shines a light lobe through the finger to measure the light communicated to the LDR.The signal gained from the LDR is changed by the amplifier and will be cleaned and provided to the ADC.

Temperature Sensor

The Temperature sensor can be sensed with the help of the LM35 sensor. This series is accurate integrated circuit sensors, whose o/p voltage is linearly related to the Celsius temperature. A Station, which is pressed directly will aware Base station and thus will not delay for heart beats to go out of the normal range.

Danger Switch

Danger switch is used to help in warning the Base Deference voltage

Environmental Analyzer

The environmental analyzer is used to find the situation of an environment such as the oxygen level and atmosphere pressure and also observe the real-time video of the soldier’s unit.

Webcam

A webcam is a device used to capture a video that is connected to a PC or computer n/w, frequently using a USB port, Wi-Fi or Ethernet, or build in for particular types of laptops.

Keypad

The keypad is a part of Human Machine Interface and plays a vital role in a tiny embedded system where human interaction is required. Matrix keypads are very simple in their architecture and also very simple of interfacing with any microcontroller.

Applications and Advantages

The applications and advantages of the health monitoring system include the following

  • No need to go on the field
  • High reliability
  • Cost effective
  • Efficient and very fast

From the above information(health monitoring system) we can conclude that it would help in tracking the health status of the soldier with measures of heart beats and also the temperature of the body. It would also assist in tracking his location by using GPS and GSM modem. It can send all information to the BSS (base station) so that more necessary action could be taken. Furthermore, any doubts regarding this concept or to implement any electrical and electronic projects, please give your valuable suggestions by commenting in the comment section below. Here is a question for you, What are the applications of health monitoring system ?

Electricity Theft Control using Smart Card

Electricity Theft Control using Smart Card

The electricity theft has appeared as a major problem in power divisions in particular in the expanding countries. A vast amount of income is lost due to this theft. In some nations this is so strict that governments are acquiring losses instead of income. In some cases government has to supply subsidies to the power division to keep a reasonable price of power. The economic loss results in lack of funds for savings to develop the existing capacity of electricity.

As a result government has not succeeded to assure the ever rising demand of electricity. Robbery electricity, avoiding a meter, billing wrongdoings and not paid bills. Billing irregularity comprises wrong meter reading taken by bribed service man. Different technical and non technical techniques were projected in the past to notice electricity stealing. Some of the technical methods to identify pilferage are utilize of central observer meter on harmonic generator, secondary terminals of distribution transformer, extreme learning machine, genetic support vector machines & a power line impedance technique.
