GPS technology is available for outdoor navigation but it cannot be used for indoor navigation. Indoor Navigation Assistant System will assist visually impaired and elderly people to navigate safely in indoor environment. The system will detect objects in the users path in real time while navigating and will give voice response if obstacle is detected

Automotive Steering Systems In a typical mechanical steering system the driver’s steering input is transmitted by a steering shaft through some type of gear reduction mechanism to generate steering motion at the front wheels. In the present day automobiles‚ power steering assist has become a standard feature. A hydraulic power steering uses hydraulic pressure supplied by an engine-driven pump. Power steering amplifies and supplements the driver-applied torque at the steering wheel so that steering

period‚ navigation was considered part of the set of seven mechanical arts‚ none of which were used for long voyages across open ocean. Polynesian navigation is probably the earliest form of open ocean navigation‚ though it was based on memory and observation rather than on scientific methods or instruments. Early Pacific Polynesians used the motion of stars‚ weather‚ the position of certain wildlife species‚ or the size of waves to find the path from one island to another. Maritime navigation using

Ignition Systems: New and Old Jeff Tuttle Period 3 9/9/04 Ignitions systems in motor vehicles have evolved in the past thirty years. Points was a simple concept but was not reliable and needed adjustment and replacement of components seemed constant. Today a magnetic sensor relays a signal to the computer which in turn sends the voltage to the selected cylinder to ignite the fuel/air mixture. There are not mechanical parts to fail or become corroded and brittle. There are many different

Celestial Navigation is the art and science of finding your way by the sun‚ moon‚ stars‚ and planets‚ and‚ in one form or another‚ is one of the oldest practices in human history. Celestial navigation‚ also known as astronavigation‚ is a position fixing technique that has evolved over several thousand years to help sailors cross oceans without having to rely on estimated calculations‚ or dead reckoning‚ to know their position. Celestial navigation uses "sights‚" or angular measurements taken between

DECEMBER 2001 Overview of Automotive Sensors William J. Fleming Abstract—An up-to-date review paper on automotive sensors is presented. Attention is focused on sensors used in production automotive systems. The primary sensor technologies in use today are reviewed and are classified according to their three major areas ofautomotive systems application–powertrain‚ chassis‚ and body. This subject is extensive. As described in this paper‚ for use in automotive systems‚ there are six types of rotational

to no longer being able to navigate with an atlas because really... it’s not necessary. Using a machine to plan your journey makes travelling less tedious and not as troublesome. Of course you can still use a traditional map; however a satellite navigation device is more accurate than a piece of paper. Gone are the days of maps obscuring your vision of the road when trying to find your position on a sheet the size of the windscreen; instead you have a 4-6 inch screen connecting to satellites and knowing

There are many different methods for air navigation. The system that a pilot uses for navigation depends on the type of flight that will occur‚ which navigation system is installed in the aircraft‚ and the navigation systems that are available in that certain area. The GPS (Global Positioning System) has become the most valuable method in the aviation industry because it is reliable‚ precise‚ and easy to use. GPS allows the pilot to pinpoint specific three or four-dimensional location data.
