describe a sudden and unexpected infant death which is initially unexplained [3]. In many cases post-mortem examinations will find a reasonable cause of death, but there are some cases where no reasonable cause is found and so the verdict of sudden infant death syndrome (SIDS) is registered. In the UK, 355 such deaths were registered in 2005 according to the UK Foundation for the Study of Infant Deaths (FSID) ; in the USA it is estimated by the Centre for Disease Control and Prevention (CDCP) that 2250 infant deaths are registered as SIDS [3]. It is noteworthy that these figures are for infants aged 0-12 months – in the UK during 2005 only 18 cases of SIDS were recorded for infants aged over 12 months, indicating that infants are most at risk from SIDS in the first twelve months of their lives. According to the National SIDS/Infant Death Resource Centre, SIDS is responsible for roughly 50 deaths per 100,000 births in the U.S. in 2004. The SIDS rate has been declining due to the awareness in caregivers and parents but it is still far higher than one would expect in such a developed country like the U.S. The costs and suffering due to the tragic occurrences of SIDS to families and societies are significant [3]. Reducing the sudden death rate in infants by an effective monitoring and alarm system is a challenge for researchers considering the syndrome usually has no obvious warning signs or symptoms. The aim of this work is to provide such a monitoring and diagnostic system which is easier to handle and less obstructive than the commonly used medical systems. Most previous approaches for the monitoring of infants provides parameters like respiration, heart rate, temperature and humidity, to detect excessive sweating, for the continuous monitoring of infants. Main goal of a proposed system is to provide more security and more parameters for incubator for the continuous monitoring of infants under clinical and home conditions. Main objective of a proposed system is 1. To monitor the parameters Like Light, respiration, Audio/ voice of the baby that he/she is ok or crying.

the monitoring of infants is proposed here. Healthcare cost is an urgent issue globally. The costs for infant care are high due to highly intensive labor. For healthy infants, Sudden Infant Death Syndrome (SIDS) is one of the most critical problems needed to be addressed and it requires a great deal of care labor. SIDS is defined as any sudden and unexplained death of an apparently healthy infant aged from One month to one year. This research work provides description of design of embedded device for monitoring of infants. The Embedded device includes sensors for Door Security, Light Intensity, Voice detection, and temperature of incubator for the continuous monitoring of infants under clinical and home conditions. It will allow the early detection of potential life threatening events. The device would involve DSP Processor TMS320C5416. It is a stand-alone development and evaluation module. It allows evaluators to examine certain characteristics of the C5416 digital signal processor (DSP) to determine if it meets their application requirements. Code Composer Studio is the integrated environment for TI’s DSP’s. CCStudio includes a suite of tools used to develop and debug embedded applications. It includes Compilers for each of TI’s Device families, source code editor, project build environment, debugger, profiler, simulators and many other features. CCStudio provides a single user interface taking users through each step of the application development flow.

INTRODUCTION

The demand of physicians for the development of monitoring and diagnostic systems which are easier to handle and less obtrusive than the commonly used medical systems is the motivation for the said work. Another motivation is the frequently expressed concern by parents about the danger of apparently life threatening events or even the problems of sudden infant’s death syndrome. Sudden unexpected death in infancy (SUDI), or cot death as it is more commonly referred to, is the term used to

oor parameter to provide Intruder bell so that it will gives alarm/Led indication if any personal will come at the place /Room of baby by breaking the sensor.

To monitor the temperature of the incubator. All these parameters are continuously monitored by system & will display the status on LEDs.

The Developed Cot Death for Infants D in Day Care system also worked on infant’s respiration. There are some proposed infant monitoring systems, such as cardiopulmonary monitoring, vision monitoring, oxygen consumption monitoring and multi-purpose monitoring. Many of these approaches are invasive Tmaking both the infant and parents uncomfortable while some of the monitoring systems are not effective enough due to the unrecognized signs or low response of SIDS [3]. In many SIDS cases, the infants stop breathing without any signs of trauma.

III PROPOSED METHODOLOGY

This proposed scheme aims to design an embedded device which supports mainly the following Features: 1. AUDIO monitoring. 2. Light sensing & Alarm/LED indication. 3. Door sensor to sense Intruder. 4. sense temperature of the incubator The device would involve DSP Processor TMS320C5416 and sensors which can be interfaced with DSP processor. The system will monitor the 4 parameters Door, Light, air temperature of that incubator, Audio/ voice of the baby that he/she is ok or crying. The Door parameter provides an Intruder bell it will gives alarm/Led indication if any person will come at the place /Room of baby by breaking the sensor. Light Intensity can be monitored by using LDR (Light dependent register). Device use temperature sensor to monitor overall temperature of the incubator. All these parameters are continuously monitored by system & will display the status on LEDs or gives alarm. DSP processors are microprocessors designed to perform digital signal Processing—the mathematical manipulation of digitally represented signals. Digital signal processing is one of the core technologies in rapidly growing application areas such as wireless communications, audio and video processing, and industrial control. Most DSP processors share some common basic features designed to support high-performance, repetitive, numerically intensive tasks. Most DSP processors share some common basic features designed to support high-performance, repetitive, numerically intensive tasks. The most often cited of these feature is the ability to perform one or more multiplyaccumulate operations (often called ―M ACs‖) in a single instruction cycle. A second feature shared by DSP processors is the ability to complete several accesses to memory in a single instruction cycle. A third feature often used to speed arithmetic processing on DSP processors is one or more dedicated address generation units.

The developed sensory baby vest for the monitoring of infants includes fully integrated sensors for the parameters respiration, heart rate, temperature and humidity, to detect excessive sweating, for the continuous monitoring of infants under clinical and home conditions. It allows the early alert for potential life threatening events as well as the recognition of the development or progression of diseases at an early stage. Health protection or even life-saving is enabled in time [1]. A variety of principles for the measurement of the parameters have been assessed for the integration into the garment. Prototypes have been manufactured incorporating the chosen sensing principles with textile and textile-compatible technologies.

A non-invasive infant monitoring system includes CO2 sensors to non-invasively monitor the exhaled air from an infant in order to reduce the potential risks for Sudden Infant Death Syndrome (SIDS) [3]. CO2 sensors placed in the crib around an infant to non-invasively monitor the exhaled air concentration variation from him/her. By monitoring the outputs of CO2 sensors, we can detect if there is anything unusual with the infant’s respiration. The output data is sent wirelessly to activate an alarm or logged for further diagnoses.

The C compiler accepts C source code and produces assembly language source code. The assembler translates assembly language source files into machine language object files. The machine language is based on common object file format (COFF). The linker combines object files into a single executable object module. As it creates the executable module, it performs relocation and resolves external references. The linker accepts replaceable COFF object files and object libraries as input. The archiver allows you to collect a group of files into a single archive file, called a library. The archiver also allows you to modify a library by deleting, replacing, extracting, or adding members. The mnemonic-to-algebraic assembly translator utility converts an assembly language source file containing mnemonic instructions into an assembly language source file containing algebraic instructions. You can use the library-build utility to build your own customized run-time-support library. The run-time-support libraries contain ANSI standard run-time-support functions, compiler utility

functions, floating-point arithmetic functions, and I/O functions that are supported by the C compiler. The hex conversion utility converts a COFF object file into TI-Tagged, ASCII-hex, Intel, Motorola-S, or Tektronix object format. The cross-reference lister uses object files to crossreference symbols, their definitions, and their references in the linked source files. The absolute lister accepts linked object files as input and creates .abs files as output. You assemble the .files to produce a listing that contains absolute addresses rather than relative addresses. Without the absolute lister, producing such a listing would be tedious and require many manual operations [10].
