Heart 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.
Temperature control is a procedure to maintain the temperature at a certain level. This method is commonly used in all regions of the world.

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

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.

The servo motor is most commonly used for high technology devices in the industrial application like automation technology. It is a self contained electrical device, that rotate parts of a machine with high efficiency and great precision. The output shaft of this motor can be moved to a particular angle. Servo motors are mainly used in home electronics, toys, cars, airplanes, etc.This article discusses about what is a servo motor, servo motor working, servo motor types and its applications.
Types of Servo Motor
Servo motors are classified into different types based on their application, such as AC servo motor, DC servo motor, brushless DC servo motor, positional rotation, continuous rotation and linear servo motor etc. Typical servo motors comprise of three wires namely, power control and ground. The shape and size of these motors depend on their applications. RC servo motor is the most common type of servo motor used in hobby applications, robotics due to their simplicity, affordability and reliability of control by microprocessors.
DC Servo Motor
The motor which is used as a DC servo motor generally have a separate DC source in the field of winding & armature winding. The control can be archived either by controlling the armature current or field current. Field control includes some particular advantages over armature control. In the same way armature control includes some advantages over field control. Based on the applications the control should be applied to the DC servo motor. DC servo motor provides very accurate and also fast respond to start or stop command signals due to the low armature inductive reactance. DC servo motors are used in similar equipments and computerized numerically controlled machines.
AC Servo Motor
AC servo motor is an AC motor that includes encoder is used with controllers for giving closed loop control and feedback. This motor can be placed to high accuracy and also controlled precisely as compulsory for the applications. Frequently these motors have higher designs of tolerance or better bearings and some simple designs also use higher voltages in order to accomplish greater torque. Applications of an AC motor mainly involve in automation, robotics, CNC machinery, and other applications a high level of precision and needful versatility.
Positional Rotation Servo Motor
Positional rotation servo motor is a most common type of servo motor. The shaft’s o/p rotates in about 180o. It includes physical stops located in the gear mechanism to stop turning outside these limits to guard the rotation sensor. These common servos involve in radio controlled water, radio controlled cars, aircraft, robots, toys and many other applications.
Continuous Rotation Servo Motor
Continuous rotation servo motor is quite related to the common positional rotation servo motor, but it can go in any direction indefinitely. The control signal, rather than set the static position of the servo, is understood as the speed and direction of rotation. The range of potential commands sources the servo to rotate clockwise or anticlockwise as preferred, at changing speed, depending on the command signal. This type of motor is used in a radar dish if you are riding one on a robot or you can use one as a drive motor on a mobile robot.
Linear Servo Motor
Linear servo motor is also similar the positional rotation servo motor is discussed above, but with an extra gears to alter the o/p from circular to back-and-forth. These servo motors are not simple to find, but sometimes you can find them at hobby stores where they are used as actuators in higher model airplanes.
Servo Motor Working
A unique design for servo motors are proposed in controlling the robotics and for control applications. They are basically used to adjust the speed control at high torques and accurate positioning. Parts required are motor position sensor and a highly developed controller. These motors can be categorized according the servo motor controlled by servomechanism. If DC motor is controlled using this mechanism, then it is named as a DC servo motor. Servo motors are available in power ratings from fraction of a watt to 100 watts.The rotor of a servo motor is designed longer in length and smaller in diameter so that it has low inertia.
