Magnetic Ram......The future RAM

Magnetoresistive Random Access Memory (MRAM) combines a magnetic device with standard silicon-based microelectronics to obtain the combined attributes of non-volatility, high-speed operation and unlimited read and write endurance not found in any other existing memory technology. We describe how the cell architecture, bit structure, and the toggle switching mode are combined to provide significantly improved operational performance and manufacturability as compared to MRAM based on conventional switching. One potential barrier to MRAM manufacturability is associated with the method of write selection in which two orthogonal currents in coincidence must write data, whereas each of the orthogonal currents alone cannot disturb the data. This "2D" selection method places constraints on uniformity of MRAM memory cells. Using a transistor per cell for write select greatly improves operating margins and lowers write currents.

Nanotechnology.......... Long life in an open world

We the humans have lived in various kinds of ages; Stone Age, Bronze Age, Iron Age, and silicon age. Each and every age has its own impact on the life of human beings. Nevertheless we are well in to the new and emerging age called 'Nano age'. The age where no one knows what is a disease? And what is aging? Imagine curing cancer by drinking medicine stirred into your favorite juice, a super computer no bigger than a human cell. These are just a few promises of nanotechnology. Nanotechnology promises to make us healthy and wealthy, and it will be able to do so without consuming any natural resources or without spewing pollution in to the environment. My paper will be focusing on how this Nano--Technology plays a vital role in improving life of humans by eliminating virtually all kinds of deadly viral diseases such as cancer and also focuses on how can we eliminate all kinds of old age diseases that are faced by the today's mankind, thereby prolonging the life of humans far beyond the current limitation, making life more enjoyable.

PAPER ON CAR SPEED CONTORLING

In the current scenario the world is plagued by accidents which are primarily due to human errors in judgment and hence thousands of lives are lost. These accidents can be avoided if only there was a mechanism to alert the driver of approaching danger. This can be done by monitoring the distance between nearby cars and alerting the driver whenever the distance becomes too short. This is precisely the aim of this paper. In this paper we propose the use of Bluetooth Technology by which we can check the speed of the car whenever it comes dangerously close to any other vehicle up front, thereby saving very many lives.

PAPER ON NOISE LESS MOBILE COMUNICATION

Conventional Microphones used in the speech accessories of mobile phones are transducers, which convert speech (sound vibrations) in to electrical signal. In addition, they also convert external noise and disturbances along with the normal speech, because of which the person at the receiving end cannot hear the exact voice clearly. This becomes a serious problem when conversing during traffic jams, riding on a bike or car.
This innovative idea deals with a noise elimination technique which facilitates noiseless conversation and the person can speak normally even in a heavy disturbing environment.

This technique uses a Laryngophone (a transducer) instead of conventional microphone in the speech accessory of cell phone. Laryngophone is a type of microphone that picks up sound directly through sensors in contact with the neck, which facilitates direct communication. It is able to pick up speech in loud environments where other types of microphones would not function well because the speech would be drowned by back ground noise.

PAPER ON VIRTUAL REALITY

ABSTRACT Our innovations have given us the power to transform our environment. Technologies have made this possible—from the simplest wooden plough to the most advanced personal computers. Throughout the journey of shaping the world, our technology went a long way in transforming our lives only physically but have you heard of a promising technology which brings about physical as well as mental transformations?. With the recent breakthrough in information technology, virtual reality has made it possible.

Virtual Reality is stimulating the user’s senses in such a way that a computer generated world is experienced as real. The computer presents the stimulating 3-D environment which creates sense of presence and deeply engaged by providing the interface using display devices like Head-Mounted Display (HMD), Binocular Omni-Orientation Monitor (BOOM), &Cave Automatic Virtual Environment (CAVE).The participant interacts with computer generated 3-D world through input devices like Data Gloves, Joysticks, Hand-Held Wands, & Body Sensors. Virtual world gives mental support to people with disabilities, cancer, AIDS, strokes, depression and other ailments, there by giving them second life. Its other applications include simulation of surgical incision, Virtual Prototyping, & Information Visualization. Thus, virtual reality brings the imagination as close and realistic as reality itself.

In short, virtual reality is the simulation of another world, the world in which the user can see through his own eyes, the world in which a user can experience his aspirations virtually and do it really, and the world which can be rightly called as his second life

PAPER ON NANOTECHNOLOGY

Abstract:

Nanotechnology broadly refers to a field of applied science and technology whose unifying theme is the control of matter on the atomic and molecular scale, normally 1 to 100 nanometers, and the fabrication of devices within that size range. It is a highly multidisciplinary field, drawing from fields such as applied physics, interface and colloid science, supramolecular chemistry, self-replicating machines and robotics and all the branches of engineering. Nanotechnology can be seen as an extension of existing sciences into nanoscale and using a modern term. Examples of nanotechnology in modern use are the manufacture of polymers based on molecular structure and the design of computer chip layouts based on surface science.
