RAPID PROTOTYPING

Rapid Prototyping Technology is a group of manufacturing processes that enable the direct physical realization of 3D computer models. This technology converts the 3D computer data provided by a dedicated file format directly to a physical model, layer by layer with a high degree of accuracy. This technology is fast developing and is more than
competitive to traditional model building techniques considering time and degree of detail. The paper gives an overview on existing major RP techniques and their applications in engineering fields.

Micromachining

Literally Micro in Micro machining implies that parts are made to the size of 1 to 999 µm. However Micro also means very small in the fields of machining, manufacture of small parts are not easy. Therefore micro components should also indicate too small components to be machined Prof. Taniguchi defines Micro Engineering as the fields where components sizes are a few millimeters. When the part size is between 100µm to 100mm, a term MESO manufacturing is also used to address such parts. In fact, the range of micro varies according to era, person, machining method, type of product or material.

FUELCELL

A Fuel cell is a device that uses hydrogen (or hydrogen-rich fuel) and oxygen to create electricity by an electrochemical process. If pure hydrogen is used as a fuel, fuel cells emit only heat and water as a byproduct. Several fuel cell types are under development, and they have a variety of potential applications . Fuel cells are being developed to power passenger vehicles, commercial buildings, homes, and even small devices such as laptop computers.

End-of-life vehicles

In Japan nearly 100% of all End-of-life vehicles (ELVs) xare recycled, with a recycling rate of 75% by vehicle weight. The auto industry hopes to increase this rate to over 90% for new vehicles manufactured after 2002 by using materials that are easier to recycle and by developing technologies that enable easier dismantling and disassembly of vehicle parts. Thus, the automobile recycling effort begins at the earliest stages of vehicle design and development in order to assure the appropriate disposal of a vehicle at the end of its service life. In addition to increased recyclability, efforts are now being made to reduce the volume of automobile shredder residue (ASR) that is generated from ELVs--and that up until now was simply disposed of in landfills--and to utilize ASR more effectively, by such means as converting it into distilled gas to recover its energy. Automobile manufacturers also help support the operations of the Association for Cooperation in Abandoned Car Disposal and a foundation that promotes the appropriate treatment of industrial waste.

Cryo Tracker

The Cryo-Tracker System was originally developed for the aerospace vehicles but can be used in any cryogenic tank. Accurate mass gauging of the cryogenic propellants loaded onto aerospace vehicles prior to launch is critical for mission success. Figure 1 shows a propellant tank loaded with densified (subcooled liquid below the normal boiling point) cryogenic propellant. Mass gauging the stratified cryogenic propellant requires knowing the tank pressure, tank volume, liquid temperature profile, and liquid level. The Cryo-Tracker® MGS is designed to measure the temperature profile and the liquid level.

BioMass gassifier

Gasification is a process that converts carbonaceous materials, such as coal, petroleum, biofuel, or biomass, into carbon monoxide and hydrogen by reacting the raw material, such as house waste, or compost at high temperatures with a controlled amount of oxygen and/or steam. The resulting gas mixture is called synthesis gas or syngas and is itself a fuel. Gasification is a method for extracting energy from many different types of organic materials.

Brake Assist System

Brake Assist System senses emergency braking by detecting the speed at which the driver presses the brake pedal and immediately applying all available power boosts .brake assistance can potentially reduce overall stopping distance by eliminating the delay caused by a common human tendency of braking hard enough or soon enough.

Biomechatronic hand

The Biomechatronic hand is to develop an artificial hand aimed at replicating the appearance and performance of the natural hand or to obtain a complete functional substitution of the natural hand.
Main problems to be solved in order to improve the performance of prosthetic hands are:
1) lack of sensory information gives to the
amputee
2) lack of “natural” command interface.
3) limited grasping capabilities
4) unnatural movements of fingers during grasping

APACHE HELICOPTERS

The Apache helicopter is a revolutionary development in the history of war. It is essentially a flying tank -- a helicopter designed to survive heavy attack and inflict massive damage. It can zero in on specific targets, day or night, even in terrible weather. As you might expect, it is a terrifying machine to ground forces.
In this edition, we'll look at the Apache's amazing flight systems, weapons systems, sensor systems and armor systems. Individually, these components are remarkable pieces of technology. Combined together, they make up an unbelievable fighting machine -- the most lethal helicopter ever created

Airmuscles

Air muscle is essentially a robotic actuator which is replacing the conventional pneumatic cylinders at a rapid pace. Due to their low production costs and very high power to weight ratio, as high as 400:1, the preference for Air Muscles is increasing. Air Muscles find huge applications in biorobotics and development of fully functional prosthetic limbs, having superior controlling as well as functional capabilities compared with the current models. This paper discusses Air Muscles in general, their construction, and principle of operation, operational characteristics and applications.

Atomic Force Microscope

Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very high-resolution type of scanning probe microscopy, with demonstrated resolution of fractions of a nanometer, more than 1000 times better than the optical diffraction limit. The precursor to the AFM, the scanning tunneling microscope, was developed by Gerd Binnig and Heinrich Rohrer in the early 1980s, a development that earned them the Nobel Prize for Physics in 1986. Binnig, Quate and Gerber invented the first atomic force microscope (also abbreviated as AFM) in 1986. The AFM is one of the foremost tools for imaging, measuring, and manipulating matter at the nanoscale

Active Suspension system

Active or adaptive suspension is an automotive technology that controls the vertical movement of the wheels via an onboard system rather than the movement being determined entirely by the surface on which the car is driving. The system therefore virtually eliminates body roll and pitch variation in many driving situations including cornering, accelerating, and braking.
This technology allows car manufacturers to achieve a higher degree of both ride quality and car handling by keeping the tires perpendicular to the road in corners, allowing for much higher levels of grip and control.
