Moving with the help of a white cane is an elusive task for the visually challenged unless they create a mental route map with recognizable reference elements. The smart cane is intended to provide the visually challenged a better walking experience. The design is incorporated with Bluetooth enabled Obstacle detection module, supported with heat detection and haptic modules. The ultrasonic range finders help in detecting obstacles. The distance between the obstacle and the user is sent to an Android device via Bluetooth. The user gets voice alerts about the distance through Bluetooth headset. Haptics module is included to warn the user of moving obstacles with the help of vibratory motors. This research work explains about the setup we used for the implementation, design details and experimental results of the measured parameters. © 2014 IEEE.

A. S, Unnikrishnan, U., and Unnikrishnan, U., “ Wearable medical devices in preventive health care Cuffless blood-pressure measurement”, in International Conference on Intelligent, Computing and Communication Devices, 2014.[Abstract]


The advent of technology has made great leaps from the conventional methods of disease treatment. Nowadays, there has been a great shift toward continual monitoring, early detection, and prevention of diseases. Complimenting to this is the innovation of wearable medical devices. Wearable medical devices are portable electronic devices embedded in the user’s outfit. This not only facilitates faster treatment but also ensures comfortable diagnostic environment for the patient. ECG and PPG signals are of prime importance when the continual monitoring of the cardiac state of the patient is concerned. Hence, using a wearable medical device, the biomedical signals can be easily obtained and interpreted. This paper discusses a method to measure blood pressure from ECG and PPG signals acquired from the device. To realize the method, various algorithms for the implementation were coded in MATLAB. The algorithm was tested on records taken from PhysioNet ATM and a private database.

Rkannan Meghalinkham, Sreedharan, P., Prabhu, V. Raghavendr, Raj, R., and Katoch, R., “Wheeled Patient Monitoring System”, in International Conference on Intelligent, Computing and Communication Devices (2014), 2014.[Abstract]


The most common and serious problem that the elderly suffers due to old age is their degrading health conditions that restrict their ability to perform life activities. Most of them require wheelchair to move even within their residence. According to WHO, there are about 1 % of world population that require wheelchair for mobility. People with debility in moving from one location to another are either bedridden or depend upon the wheelchair. An elder, dependent on wheelchair, often requires regular health check-up to keep track of their health status, and it is very difficult for them to have frequent visits to hospitals. Wheeled patient monitoring system (WPMS), in such a situation, is a system that continuously monitors the health condition of the patient by measuring body temperature, blood oxygen saturation in blood and heart rate. These three parameters are the crucial parameters of a body and help the doctor to diagnose easily. WPMS constantly monitors health parameters and identifies critical situations to inform physicians and healthcare centres so that the users are taken care at the earliest. The system can be easily attached to or detached from the wheel chair. WPMS can also be used by patients at hospitals.

K., “Assistive technology for elders: Wireless intelligent healthcare gadget”, in Proceedings - 2011 IEEE Global Humanitarian Technology Conference, GHTC 2011, Seattle, WA, 2011, pp. 296-300.[Abstract]


Improving the quality of life for the elderly persons and giving them the proper care at the right time is the responsibility of the younger generation. But due to lack of awareness on proper elder care, unavoidable busy schedule etc. the elderly population is seem to be quite ignored. In such a scenario we are trying to find an amicable solution to this problem using a compact and user friendly system design. The proposed system is a compact device which has various wearable sensors all attached inside a glove. It has a process flow controller module and a communication control module. These modules perform together to excite an alert mechanism to the relatives or to the doctors via an SMS or a voice call to their mobile phones, whenever some critical situations arise. The system measures the heart rate, oxygen content in blood, body temperature and the pressure of the elderly person, which are the important parameters for a proper diagnosis. © 2011 IEEE.

Efficient monitoring of physiological signals of injured people in a disaster affected area is always a challenging and tedious task. In this paper we propose an emergency medical service system which can be used in disaster hit areas. Our proposed system aims at reducing this problem and help doctors to serve the injured and save lives. The system designed is easily portable. This system can also be efficaciously link the disaster affected community with the doctor who is willing to assist from anywhere in the world. The proposed portable system can measure physiological signals of people without the requirement of elaborate patient monitoring system, which also consumes lot of power. The expedite response underpins our system and by its exclusive usage in the most challenging environments makes it a perfect solution for patient monitoring in disaster affected areas. The experimental results show the performance of our system is comparatively similar to the manually measured parameters. © 2010 ACM.

Developing countries are struggling to meet the electric power demands of fast expanding economies. Added to this is the poor infrastructure which has not kept pace with the increasing demand. Quality of supply too is gaining in importance. Poor metering and billing has rendered huge losses for utilities. Tampering and fraud is also rampant. Introducing Advanced Metering Infrastructure will go a long way in mitigating many of these problems. This paper details the development of Advanced Metering Infrastructure incorporating features to monitor supply parameters and perform functions like real time billing and alerts against overvoltage and overcurrent. The proposed meter is to utilize the capabilities of ADE7758 IC as well as microcontrollers such as ATMega16. © 2011 IEEE. More »»

In this paper we discuss about the Design of an Automated Wireless Carpooling System (AWCS), which can curtail the over usage of on road vehicles to a considerable amount. This system is designed for private vehicle owners who commute individually from the workplace to home. The system makes use of pre registration method, by which only identified people get into the carpool vehicles so that crime can be reduced. The Central Monitoring system (CMS) used here intelligently handles carpool requests and switches them efficiently. The user can acquire details of his/her travel by sending a SMS from their mobile phone. Waiting centers are allocated at each part of the city and the users can enter the carpooled vehicles only from these waiting centers. A person is assigned at each waiting center to check the identity of the people entering. Thus the proposed AWCS can be implemented in a city efficiently. © 2011 IEEE.

Rajesh Kannan Megalingam, Nair, R. N., Prakhya, S. M., and Mohan, M., “Low power, intelligent, wireless, home security system for the elderly people”, in ICECT 2011 - 2011 3rd International Conference on Electronics Computer Technology, Kanyakumari, 2011, vol. 4, pp. 320-324.[Abstract]


In this paper, we suggest a Low Power Intelligent, Wireless, Home Security System (IWHSS) for Elders. The elders can avail the services of this IWHSS, conveniently within their room. If the elder is uncomfortable with a stranger trying to get into the home, services of IWHSS can be availed. The strangers can be identified and in emergency situations where the elder feels the necessity of the external help, the police and relatives can be informed via IWHSS. In addition to informing the police, the system also activates an emergency alarm to alert the neighbors. The elders can also see the stranger at the door and make a conversation with them. The system uses GPRS Modem which is interfaced directly with PIC 16F877A microcontroller to make the system power efficient. We have used low cost RF modules, PIC 16F877A microcontroller, IR-TSOP modules and Image Capture module as part of the hardware implementation of the system. The simulation software's used were MPLAB IDE and PROTEUS. © 2011 IEEE.

Rajesh Kannan Megalingam, Nair, R. N., and Prakhya, S. M., “Automated voice based home navigation system for the elderly and the physically challenged”, in International Conference on Advanced Communication Technology, ICACT, Gangwon-Do, 2011, pp. 603-608.[Abstract]


In this paper, we propose an Intelligent Home Navigation System (IHNS) which comprises of a wheelchair, voice module and navigation module. It can be used by an elderly or physically challenged person to move inside the home without any difficulty. It's common that the elders forget the way to the different rooms in house and the physically challenged people find it hard to move the wheel chair without external aid. By making use of IHNS, elderly and the physically challenged can go to different rooms in the house like kitchen, living room, dining room etc by just speaking a word which is predefined to that particular room. The voice of the person is detected by voice capture module which will be compared by voice recognition module with predefined voices loaded in to the system. According to the received voice, the destination is automatically understood and the wheelchair moves according to the route which is predefined. It is also equipped with obstacle avoidance technique, where the person may not be able to provide proper voices at the right time. The wheel chair can automatically navigate from one point to the other in the home as per predefined route based on the voice received. Thus the above proposed system can be used by elderly and physically challenged people in day to day life even if they are alone at home. © 2011 Global IT Research Inst.

In today's world there is a growing demand for real-time implementation of cryptographic algorithms which are being used in secure communication systems, networks and security systems. Traditional computing techniques involved the use of application specific integrated circuits to achieve high performance but with extremely inflexible hardware design meanwhile the flexibility of hardware design was achieved at the cost of slow processing by using general purpose processors. In this research paper a novel reconfigurable processor architecture has been presented for cryptographic applications that bridges the above mentioned gap and also sustains implementations that can show equal or even better performance results than custom-hardware and hitherto preserves all the flexibility of general-purpose processors. We present implementations for representative algorithms of block cipher such as Rijndael, RC5 and RC6 on our architecture. The RTL Description is done in ModelSim using Verilog HDL and the results are synthesized in Synopsys. This work presents an emerging reconfigurable hardware that potentially delivers flexible high performance for cryptographic algorithms. © 2011 IEEE.

A WSN is a constellation of spatially dispersed independent sensors that can collaborate among themselves and a central monitoring station (CMS) to observe physical or environmental phenomena. A sensor node, also known as a mote, is a node in a WSN that can perform some processing, acquire sensory data and communicate with other nodes in the network. Employing a wireless monitoring system will allow remote supervision, simultaneous supervision of multiple patients over a single server and better mobility and less clutter in the intensive care units (ICU). Since the monitoring system is wireless, the server can be kept out of the vicinity of the patient. This will free the fuddle caused by monitoring instruments in the ICUs. In this paper we propose to use a WSN mote with very basic functions. For instance, the sensor for monitoring pulse can be interfaced with a basic mote platform which will then be a part of the active wireless sensor network in the ICU with a unique mote ID enabling discrete monitoring over a remote server. Motes are available only in developed nations which are very generic and have many unwanted functionalities which warrants for the very high cost when shipped to developing nations like India. We propose an indigenous design specifically crafted for medical applications that do away with all the unwanted functionalities and hence would be much more affordable and hence employable in economically confined applications.

Rajesh Kannan Megalingam, Vineeth, R., Krishnan, M. U. D., Akhil, K. S., and Jacob, D. C., “Advanced network based wireless, single PMS for multiple-patient monitoring”, in International Conference on Advanced Communication Technology, ICACT, Gangwon-Do, 2011, pp. 1587-1592.[Abstract]


Real-time monitoring of the physical condition of the patients is one of the major challenges faced by hospital authorities nowadays. All the hospitals today have one Patient Monitoring System (PMS) per patient. Also human intervention is needed frequently for critical patients. In this paper we propose a network based Wireless Single PMS (NWSPMS), which can monitor multiple patients to measure various physical parameters. This must be precise, fast and effective for transmission of information about their health condition to the concerned. Also there lies a need to transmit more parameters and more data for the convenience and fast response by the staffs in the hospital. Since we need an immediate response, we make use of the voice-call facility apart from the SMS mechanism via an GSM modem. The system proposed here monitors blood pressure, heart beat rate, body temperature and ECG of the elderly patient thus giving an overall condition of the patient. © 2011 Global IT Research Inst.
