Hospital beds are mainly designed to carry static load of patients and to provide more comfort to them by means of their ergonomic design. As a result, in the case of bed ridden patients bystanders will have to put in a lot of effort to move the patients to various positions, which are essential for their quick recovery. Patients will also have to be moved to various positions in order to prevent further complications in their existing medical conditions. Hence an affordable bed having various movements to bring the patients into suitable comfort positions becomes a necessity. The authors aim to solve these problems by the development of a conceptual bed here onwards known as care bed. Care bed is a novel concept which, by providing an additional side wise movement to the bed in addition to the bed to wheel chair transformation movements. As a surplus benefit of this added movement, easy transformation of patients from bed to stretcher became much simpler and easier to accomplish. The basic idea of care bed involves dividing the bed into three portions laterally as well as longitudinally, thus making a total of nine pieces. These pieces are joined by means of a hinge to allow relative movement between them. The hinges also restrict movements to that along only one axis at a time. So when bed to wheel chair transformation movement take place, the side wise panel movement does not cause any sort of hindrance and vice versa. The movements of the panel are accomplished by, means of single phase ac induction motor through the employment of power screw mechanism. This greatly helped to reduce the cost and complexity, that might have come into play when hydraulic or pneumatic systems may have been involved. By providing movement along the longitudinal and transverse axis, it became possible to rectify the conditions which might have culminated in the occurrence of hazardous pressure ulcer. In a nutshell it can be said that, care bed is a product that cater to the woes of bystanders as well as the patients and can be regarded as one among the rare attempts to do so. With the increasing number of bed ridden patients owing to various new ailments, increasing accidents and the rise in old age population, the product finds wide variety of application in the present and future times.

Our project aims to design and prototype an Innovative Walking Stick for the Physically Challenged and the elderly. Our research studies revealed that the aforesaid communities still long for an innovative mobility-aid for their subsistence. The studies have further underlined the fact that such people prefer to use a walking stick or a walker over a wheelchair in public. Conventional walking stick is designed exclusively to provide assistance for walking. Apart from improvising the basic purpose of a walking aid, I-WaK makes life simple and effortless for the handicapped people with its additional features. I-WaK is a walking stick which can be transformed into a walker at will. I-WaK is a three legged walker which can be assembled into a single piece walking stick using scissor mechanism and a motor. Thus I-WaK serves as a conventional walking stick and renders additional support when navigating through crowds, steep roads, wet paths etc. as a walker. The main features of I-WaK includes walker with two additional legs to the main leg, by means of a scissor mechanism. Scissor mechanism transforms the I-WaK into a walker and engages a seating arrangement. I-WaK is made portable and compact by the use of scissor mechanism.

The power demand in our country is increased so that there is a consistent power cut in rural areas. This is because of high power consumption by factories and also due to less availability of non-renewable energy resources. So it is a known fact that the application of hybrid renewable energy system to generate power at economic, quick, reliable answer to the rural household’s need for power. This Solar-wind energy system can be considerably reducing of our power requirement in rural areas. But, the wind speed is varying both day and night time the produced electricity through horizontal axis wind turbine. To overcome this, issue the vertical axis Savonius Wind Turbine (SWT) with guide vanes has been introduced for producing electricity at low wind speed (cut in speed approximately 3m/s) by combining both SWT and solar photo-voltaic (PV), the hybrid design had been fabricated. The hybrid controller has been selected for the rated power output of the proposed system. In this study, the power generation through Vertical VASWT and PV hybrid system achieved the overall efficiency of 22% for the stand alone system for electricity generation. In this study the optimized design of VASWT has been selected and the performance study has been done with addition of PV panel and modified automobile car alternator.

Pages: 321 - 325
XML is a standard for exchanging and presenting information on the Web because XML makes data flexible in representation and easily portable as well. However, XML data is also recognized as verbose since it heavily increases the size of the data due to the repeated tags and structures. The data verbosity problem gives rise to many challenges of conventional query processing and data exchange. The XML increase the overhead of bandwidth-and memory-limited devices. XML compression and optimization are one of the solutions of the verbosity problems of XML. Although many effective XML compressors, such as XMill, have been proposed to solve the data size problem but it does not address the problem of running queries on compressed XML data. Other compressors have been proposed to query compressed XML data. However, the compression ratio of these compressors is usually worse than that of XMill and that of the generic compressor gzip, while their query performance and the expressive power of the query language they support are inadequate. The main objective of this work is in two folds; first design and development of XML compression method and second optimization of existing methods of XML compression. In addition, the increased size affects both query processing and data exchange. XML files require a lot more storage space and network bandwidth.

Robotic lower limb exoskeletons have been built for augmenting human performance, assisting people with disabilities, studying human physiology, and re-training motor deficiencies. The main function of a powered exoskeleton is to assist the wearer by boosting their strength and endurance. Our project aims to develop an ergonomic, cost effective, yet powerful exoskeleton to aid the disabled and soldiers. We plan to use a light weight, but stiff material capable enough to handle the compressive stresses developed by the weight of the user. The links are driven using independent motors. Electric motors are used for the actuators due to their higher efficiency and lower weight. The system is fastened to the wearer using broad Velcro strips to employ universal compatibility and to avoid discomfort. The current system uses a pre-programmed microcontroller to actuate the motors. The speed and number of revolutions are determined in accordance with the human gait cycle. In order to obtain the required motion, sprockets are used along with simple cable -pulley system, thereby decreasing the overall weight of the system. The pace can be altered by suitably changing the voltage supplied to the motors using the driver circuit. The primary benefactors of the product will be the senior citizen, whose numbers are expected to shoot up to 70 percentages by 2050. So an ergonomic and cost effective exoskeletons market is expected to go nowhere but upwards. The links of our product are so designed to be 95 percentile human, so that it fits practically everyone. Provisions for small adjustments are also provided for additional comfort. The compact and vertical design not only creates an aesthetic appearance. It is also commendable that the existing technological exoskeletons rest a fortune and hence has not achieved a great appeal in the market. It is in this context that our cost effective exoskeleton becomes commercially important.
