A new technique for creating films of barium titanate (BaTiO3) nano particles in a polymer matrix could allow fabrication of improved new powerful capacitors able to store twice as much energy as conventional devices. The improved new powerful capacitors could be used in consumer devices such as cellular telephones – and in defense applications requiring…
Super Charger Engines combust (burn) fuel and use the energy of that combustion to do work. The more fuel that is combusted in any given time then the more energy is available to carry out the engines task. Fuel requires air (or the oxygen contained within air) to burn so if there isn’t enough air…
Turbo-Charger A turbocharger is actually a type of supercharger. Originally, the turbocharger was called a “turbo super charger.” Obviously, the name was shortened out of convenience. A turbocharger’s purpose is to compress the oxygen entering a car’s engine, increasing the amount of oxygen that enters and thereby increasing the power output. Unlike the belt-driven supercharger…
Variable Turbo Chargers Variable geometry turbochargers (VGTs) are a family of turbochargers, usually designed to allow the effective aspect ratio (sometimes called A/R Ratio) of the turbo to be altered as conditions change. This is done because optimum aspect ratio at low engine speeds is very different from that at high engine speeds. If the…
microprocessor are essential for many of the products we use every day such as TVs cars, radio, home appliance, and computers. microprocessor based controls also called microcontrollers. microcontroller is a digital integrated circuits which serves as a heart of many modern control applications.
microprocessor and microcontrollers are similar but the architecture of the both differs in the applications domains. microprocessor are employed for high speed applications such as desktop and laptop computers whereas the microcontroller are employed in automations and control applications such as microwave ovens, automatic washing machines, dish washers, engine management system, DVD players etc.
Taptic Engine In older days tiny joysticks are used in Laptop’s which are replaced by touch pad’s. Later touch pad’s with the function of separate mouse buttons feel immense. Already the latest gadgets have multiple fingers at once, Pinch to zoom and scrolling with two fingers. Latest technology adapted to the Apple’s watch, Macbook Pro…
Components of a common rail system In the common rail system, a pressure sensor measures the fuel pressure in the rail, its signal valve is compared with the desired value stored in the engine computer. If the measured value and the desired value are different, an overflow orifice in the pressure regulator on the high…
Hybrid Drive Trains Hybrid vehicles The term Hybrid drive denotes such vehicle drives with more than one drive source. Hybrid drives can incorporate several similar or dissimilar types of energy stores and/or power converters. The goal of the hybrid drive developments is to combine different drive components, such that the advantages of each are utilized…
Speed Governor The governor is a device which is used to controlling the speed of an engine based on the load requirements. Basic governors sense speed and sometimes load of a prime mover and adjust the energy source to maintain the desired level. So it’s simply mentioned as a device giving automatic control (either pressure…
STEERING The steering system in a vehicle is used to move the vehicle in a particular direction. This is a very important sub-system in a car without which it would be impossible for a vehicle to follow its desired path. The steering system can be used to steer all kinds of vehicles like cars, trucks,…
Touch screen technology in fast few years has grown drastically in various applications, in order to overcome the difficulties faced by the touch screen; a new frontier technology has to take its part to revitalize the use of touch screen. In this counterpart gorilla glass has thrown a flash light focus on touch screen technology….

Aerogel is a very special type of foam which is 99.8% air. Aerogel is a low-density solid-state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties, most notably its effectiveness as a thermal insulator. Aerogels…
LEDs won’t burn your hand like some light sources, but they do produce heat. All light sources convert electric power into radiant energy and heat in various proportions. LEDs generate little or no IR or UV, but convert only 20%-30% of the power into visible light; the remainder (70%) is converted to heat that must…
