N.P. Suh (), D.H. Cho, C.T. Rim. KAIST. The Online Electric Vehicle (OLEV), developed by KAIST, is an electric vehicle that can be charged while stationary or driving, thus removing.

This device, which produces high voltage, high frequency alternating currents, enabled Tesla to transfer power over short distances without interconnecting wires via resonant inductive coupling, the near-field wireless transmission of electrical energy between two magnetically coupled coils. The road has a smart function as well, to ksist OLEV buses from regular cars–the segment technology is employed to control the power supply by switching on the power strip when OLEV buses pass along, but switching it off for other vehicles, thereby preventing EMF exposure and standby power consumption.

OLEV has a small battery one-third of the size of the battery equipped with a regular electric car.

South Korean road wirelessly recharges OLEV buses

Wireless charging in the UK is not without its critics. However, the U shaped cores also require return cables which bumps up the cost of production.

It takes about 30 minutes for OLEV to fully charge and they can travel for 40 kilometers between charges about 24 miles and that means they could potentially veer off the established charging route on occasion if they needed to. In response to the cost issue of gen 2, the third generation OLEV was developed. Oleb OLEV system is split into two main parts: The vehicle complies with the international electromagnetic fields EMF standards of The test vehicle, a sports car converted into an electric vehicle, managed to travel the entire route at a moderate speed while simultaneously charging its battery.

The scientists have managed to reduce the number of bulky ferrite sheets by using coil systems, which also reduces the cost.

In Italy, such a system has been in use in Genoa and Turin for over ten years, providing 10 to 15 percent of the power for 30 electric buses which recharge at each bus stop. Fraunhofer’s inductive charging coil for electric cars [Image source: KAIST, via Wired Magazine ] Alongside innovative battery technology, another potential method for kaiet electric vehicles EVs could be wireless energy transfer strips installed on road surfaces.

A wireless parking charge system on display at a motor show [Image source: IWES found that even when a car is 20 centimeters away from a coil embedded in the road, an efficiency level of between 93 and 95 percent is still achievable across the entire power range from watts to 3.

These tests will have a total duration of about 18 months after which more on-road trials would probably need to be conducted. Two other Fraunhofer institutes, the Fraunhofer Institutes for Manufacturing Technology and Advanced Materials IFAM and for Transportation and Infrastructure Systems IVI, have successfully tested wireless transfer systems for use in cars, using a meter-long test route with coils embedded in the road.

It functions by using a segmented “recharging” road that induces a current in “pick-up” modules on the vehicle. The inverter accepts 60Hz 3-phase or voltage from the grid to generate 20k Hz of AC electricity into the cables.

This is kaisr a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living. Use dmy dates from May Attached beneath the vehicle, are “pick-up” modules, or the secondary coils, that consist of wide W-shaped ferrite cores with wires wrapped around the center.

Bhore Committee () and its Relevance Today The Bhore Committee begins w~.th a (*Source for data: World Development Report, World Bank).

The Universal Immunization Programme UIP was launched in to provide universal coverage of infants and pregnant women with immunization against identified vaccine preventable diseases. It laid out the proposal for a national program of health services in India and also stressed the importance of preventive care in addition to curative treatment. Short-term measure — one primary health centre as suggested for a population of 40, The National Rural Health Mission 5 is a major undertaking by United Progressive Alliance Government to honor its commitments under common minimal programme.

Though most of the recommendations of the committee were not implemented at the time, the committee was a trigger to the reforms that followed.

These set of strategies are Core Strategies- Train and enhance capacity of Panchayati Raj Institutions to own, control and manage public health services. The committee consisted of pioneers in the healthcare field who met frequently for two years and submitted their report in The political commitment to rural health and access to primary health care that the CMP articulated was itself a matter of considerable cheer.

In addition, there is a prerequisite to allocation of funds to states requiring signing of Memorandum of Understanding with Government of India, stating the agreement to the policy framework of NRHM and timeliness and performance benchmarks against identified activities.

It has been observed that health care system has expanded considerably over last few decades but quality of services are not upto the mark.

Lack of sensitization among service providers, weak coordination among various stakeholders, unorganized public sector infrastructure and poor living environment further compounded problem of urban poor. Secondary health centrewas also envisaged to provide support to PHC, and to coordinate and supervise their functioning. Health status and access of RCH services of slum dwellers are poor. India has come quite close to Alma Ata Declaration on Primary Health Care made by all countries of the world in 3.

Although a step in forward direction, these changes may weaken the institution of PHC and focus on specialized medical care services at CHC level. Retrieved from ” https: Risk pooling and social health insurance to provide health security to under-privileged population. The first concern is that there is buore systematic analysis of previous policies and no major lessons seem to have been learnt from the past.

commiittee The report, submitted inhad some important recommendations like: But these integrative strategies are limited to RCH and family welfare programmes with no intention of touching three major disease control programmes Malaria, AIDS, TBthat has been verticalised as a part repodt Millennium Development Goals MDG linked to market needs of large pharmaceutical industries.

National Health Policy gave a general exposition of the policies which require recommendation in the circumstances then prevailing in health sector.

Bhore Committee was set up by Government of India in Primary Health Centres were built across the nation to provide integrated promotive, preventive, curative and rehabilitative services to entire urban as well as rural population, as an integral component of wider community development programme.

A Critical Review S Goel. It involves sustaining the high immunization coverage level under UIP, and augmenting activities under Oral Rehydration Therapy, prophylaxis for control of blindness in children and control of acute respiratory infections.

InGovernment made a major move in health politics by coming up very sharply against the health work done in the country in last 35 years.

One will hope and wish that increased awareness and collective power of the people along with detailed guidelines and standards provided in the mission, NRHM will be implemented in letter and spirit to bring sea change in our primary health care system and benefits the disadvantaged segments of population.

National Health Policy was thus formed in 4 to make architectural corrections in health care system.

InDommittee was the first country to launch a national programme emphasizing family planning to stabilize the population at a level consistent with the requirement of national economy. A long-term programme also called the 3 million plan of setting up primary health units with 75 — bedded hospitals for each 10, to 20, population and secondary units with — bedded hospital, again regionalised around district hospitals with beds. The major aim of the committee was to survey the then existing position regarding the health conditions and health organisation in the country and to make recommendations for future development, in order to improve public health system in India.

For mission to achieve its goals, the growing.

It said,”If it was possible to evaluate the loss, which this country annually suffers through the avoidable waste of valuable human material and the lowering of human efficiency through malnutrition and preventable morbidity, we feel that the result would be so startling that the whole country would be aroused and deport not rest until a radical change had been brought about.
