The most essential automation is saving human life, saving their belongings, protecting their properties and making arrangements in a systematic way for automation. This paper deals with the design of a real time Human Limb which acts according to the design configurations of the prescribed datas as per the sensor calibrated. This research proposes to overcome current limitations using three axis optimal inertial sensors combined with an Embedded Controller on which the filter algorithm as well as analog to digital converter is implemented for correcting drift and angular motion through all orientations. The mechanical design will have miniature or hybrid stepper motors with associated mechanical elements to move the limbs on all the axis like up/down ,roll, elevation and azimuth. Source

This paper presents an experimental investigation of human skin. It can be easily examined with the eyes; however, many particular aspects of the skin are better evaluated by non-invasive methods. Then it describes a method that helps in detection of suntanned or precancerous skin using gross-over all image segmentation. A skin cancer can become highly invasive and lethal if not treated at the earliest possible stage and it aims to eliminate the need for a patient to undergo biopsy as a means of basic diagnosis for melanoma. Generally UV rays from the sun and other sources can damage skin cells causing cells to grow abnormally. Melanoma is considered as one such dangerous type of skin cancer. The main cause of melanoma is excessive exposure to UV radiation reaching the skin. When compared to the normal skin the structure of abnormal skin as an irregular outer epidermal layer as well as the inner dermal layer. In this paper all types of skin viz normal skin, suntanned and pre-cancerous can be tested it also diagnosis the freckle (mole) and congenital nevi (moles that appear at birth). © Research India Publications.

An efficient hardware solution to perform table lookup is the content addressable memory (CAM). A CAM can be used as a co-processor for the network processing unit to offload the table lookup tasks. Besides the networking equipment, CAMs are also attractive for other key applications such as translation look-aside buffers in virtual memory systems. Ternary content addressable memories (TCAMs) are hardware-based parallel lookup tables with bit-level masking capability. A special logic unit, named Multiple Match Resolver (MMR), is required to resolve the best candidate if more than one words indicate a "match". In the early development of TCAM, the capacity was small, with only a few hundred to several thousand words. The design of MMR was relatively easy, and could be realized using static digital logics. They are attractive for applications such as packet forwarding and classification in network routers. Despite the attractive features of TCAMs, high power consumption is one of the most critical challenges faced by TCAM designers. This work proposes circuit techniques for reducing TCAM power consumption. The main contribution of this work is divided in two parts: (i) reduction in match line (ML) sensing energy, and (ii) static-power reduction techniques. The ML sensing energy is reduced by employing (i) positive-feedback ML sense amplifiers (MLSAs), (ii) low-capacitance comparison logic, and (iii) low-power MLsegmentation techniques. Here this technique was used in CAM memory which is combined with RAM memory to enhance the performance level while searching data from memory. The focus of this work is not on the TCAM memory cell design, but rather, it is on the low-power circuit techniques for multiple match resolution and detection in TCAM. Both digital techniques and mixed-signal techniques are presented and analyzed in details. Source

Blind navigator to navigate the blind and visually impaired people with embedded based system is proposed in this paper. Blind Navigator would detect an object or obstacle and guide the blind with the use of audio instructions and vibrations. The main concept behind the system is to operate when the disabled is in need. The embedded system is dedicated to specific tasks, which can optimize a embedded designed system to reduce the size and cost of the product and increase its reliability and performance. The blind navigator mainly uses camera and Infrared sensor (IR sensor). A microcontroller (or MCU) is a computer-on-a-chip used to control electronic devices. A typical microcontroller contains all the memory and interfaces needed for a simple application. The APR sound system is used for audio instruction and relay controlled vibration motor is used for vibration. The importance of our system is, it is used for both indoor and outdoor navigation. © Research India Publications. Source

This paper presents the results of our studies concerning the implementation and exploitation of Geographical Information System (GIS) dedicated to the support and assistance of decisions requested by drought management. In this study on diverting of surplus water through canals, ponds and check dams in the study area was carried out. The remote sensing data and GIS data was used to identify the drought prone villages in Sivaganga taluk and to generate present landuse, drainage pattern as well as slope and contour. This analysis was carried out for diverting surplus water through proposed canal and pond. The results of the study indicate that if the surplus water from the ponds and streams are diverted to the drought villages in Sivaganga taluk, it will definitely improve the agricultural production due to availability of water in the ponds. The improvements in agricultural production will help to improve the economical condition of the farmers in the region. Source
