Abstract

It is well established fact that the process atomization offers the advantages like high accuracy, power saving, manpower saving, reduction in wastage, high & efficient production volumes. In the modern industries precise monitoring, & controlling of temperatures & fluid level of various chemicals in storage tanks at various places is an essential requirement. This paper describes the development of Wireless Embedded System by using Atmel's 89C51 microcontroller for monitoring & control of process parameters from remote site .The system utilizes ASK transmitter & receiver for transmission and reception of reference values i.e., temperature and fluid levels from transmitter to receiver. Interaction with transmitter is done through matrix keypad. A TRIAC AC power controller circuit is used in the receiver which controls the flow of power to the heater. The fluid level is maintained by a water feed pump .User friendly Software is developed using 8051's Assembly language to control the transmitter and receiver units.

The most common adverse event in adults/patients is fall. The fall management has always caused a major challenge in medical systems. Fall in adults/patients can cause major health complications that can ultimately leads to health decline and increases the medical care cost. Many of latest technologies have been in use for fall management like GPS enabled Tri-axial Accelerometers (MEMS), Gyroscopes and Magnetometers etc. This paper presents human fall detection system by using a inexpensive approach of Liquid Fall Detection System (LFDS). It uses GSM architecture for information transformation through SMS. It is also GPS-Based location awareness fall detection system that facilitates immediate positional information to the caretakers. Obviously, the integration of location awareness, GSM and fall detection technologies fulfills the requirements of delivering critical information to respective persons.

Abstract:Various wireless communications is often essential in the field of tele-medicine, home security and industrial security etc. Now a day"s people of all age groups are suffering from two common medical ailments that are Blood Pressure and Blood Sugar. Monitoring of these parameters or Bio-vitals has always been a challenging task to the research community. There are many parameters which always require constant monitoring like Blood pressure, Heart rate or pulse, ECG, Body temperature etc. The blood pressure is a very critical bio-vital as it is directly related to heart. Hence, in-turn measurement of heart rate is highly essential. Timely remedial medical measures/assistance can save the heart patient from heart failure. Advanced technologies are available to monitor the heart rate. The heat rate/pulse rate can be measured at any point on the body where artery"s pulsation pressure is transformed to the body surface by pressing it with index & middle finger. This traditional/conventional method is being used by physicians. The other method is using of digital devices. Latest development in microcontrollers, wireless communications techniques, GSM & GPS technologies, high sensitive wearable sensors have led the monitoring of heart rate more accurate, thus helps the patients to move around without restriction or otherwise patients are confined to the hospital environment. This paper describes a simple 51 architecture based low cost real time heart rate/pulse rate monitoring system that uses digital device OMRON NIBP unit. For clinical trials, the system was taken to the hospital and tested on different age & weight people. Then these results are compared with readings taken by Doctor using traditional methods. The developed system also uses GSM & GPS technologies. The GSM is for bio-vital signal information transformation through SMS and GPS is for location awareness. The developed system is aimed at aged or elderly people, as the movement of these people is restricted because of age factor &other health related issues. Combination of various technologies in a single module fulfils the needs of delivering critical information to concerned people.
