hi this is neelesh, final yr engg student from vardhaman college of engg. I need a brief information about automation of hydraulic jack which may be used in a four wheeler
i've already made the design which s ready with me but the thing is i need to get it done within certain limits with exact calculation of how much load s lifted nd torque needed etc etc
if u hav any idea could u plz mail it to the below givem mail address
email-id- [email protected]

with regards
neelesh ....etc

MICROELECTROMECHANICAL SYSTEMS (MEMS)
ABSTRACT
Micromechatronic is the synergistic integration of microelectromechanical systems, electronic technologies and precision mechatronics with high added value.
This field is the study of small mechanical devices and systems .they range in size from a few microns to a few millimeters. This field is called by a wide variety of names in different parts of the world: micro electro mechanical systems (MEMS), micromechanics, Microsystems technology (MST), micro machines .this field ....etc

AUTOMATIC ELECTRO-HYDRAULIC JACK FOR FOUR WHEELER
SYNOPSIS
This project work titled “AUTOMATIC ELECTRO-HYDRAULIC JACK FOR LIGHT VEHICLE” has been conceived having studied the difficulty in lifting the any type of light vehicles.
Our survey in the regard in several automobile garages, revealed the facts that mostly some difficult methods were adopted in lifting the vehicles for reconditioning.
Now the project has mainly concentrated on this difficulty, and hence a suitable electronic control unit has been desig ....etc

INTRODUCTION
This project automatic electro-hydraulic jack for light vehicle garages has been developed to the needs of small and medium automobile garages.
In most of the garages the vehicles are lifted by using screw jack. This needs high man power and skilled labors.
In order to avoid all such disadvantages, this automatic electro-hydraulic Jack has been designed in such a way that it can be used to lift the vehicle very smoothly without any impact force. The operation is made be simple that even any person c ....etc

Micro-electro Mechanical Systems (MEMS)

Introduction
The satellite industry could experience its biggest revolution since it joined the ranks of commerce, thanks to some of the smallest machines in existence. Researchers are performing experiments designed to convince the aerospace industry that microelectromechanical systems (MEMS) could open the door to low-cost, high-reliability, mass-produced satellites.MEMS combine conventional semiconductor electronics with beams, gears, levers, switches, accelerometers, diaphragms, microfluidic thrus ....etc

ABSTRACT:

Micro Electro Mechanical Systems (MEMS) in the field of biomedical industry has given rise to Bio MEMS. These encompasses Biosensors, Bio instruments and tools, Bio testing and analysis etc. Bio MEMS present a great challenge to engineers to design and manufacture of these types of sensors and instruments. Biosensor serves as the interface between living and electronic systems. These systems and the sensors should not affect the behavior of the living systems. Thin “ film microelectr ....etc

Micro-electro Mechanical Systems

Micro-electromechanical systems (MEMS) is a technology that combines computers with tiny mechanical devices such as sensors, valves, gears, mirrors, and actuators embedded in semiconductor chips.

Overview
MEMS are already used as accelerometers in automobile air-bags. They've replaced a less reliable device at lower cost and show promise of being able to inflate a bag not only on the basis of sensed deceleration but also on the basis of the size of the person th ....etc

ABSTRACT
Brake performance can be divided into two distinct classes:1) Base brake performance2) Controlled brake performance.A base brake event can be described as a normal or typical stop in which the driver maintains the vehicle in its intended direction at a controlled deceleration level that does not closely approach wheel lock. All other braking events where additional intervention may be necessary, such as wheel brake pressure control to prevent lock-up, application of a wheel brake to transfer torque across an open differential, or appl ....etc
