How does an Accelerometer Work?

WHAT IS AN ACCELEROMETER?

An accelerometer is an instrument for measuring acceleration, detecting and measuring vibrations, or for measuring acceleration due to gravity (inclination). Accelerometers can be used to measure vibration on vehicles, machines, buildings, process control systems and safety installations. They can also be used to measure seismic activity, inclination, machine vibration, dynamic distance and speed with or without the influence of gravity.

HOW DOES AN ACCELEROMETER WORK?

Used for calculating acceleration and measuring vibrations, the accelerometer is capable of detecting even the slightest movements, from the tilting of a building to smallest vibration caused by a musical instrument. Inside the accelerometer sensor minute structures are present that produces electrical charges if the sensor experiences any movement.
Accelerometers need to be placed on the surface of the object in order to determine the vibrations. It is not capable of work in isolation or apart from the object it is required to assess, it must be firmly attached to the object in order to give precise readings.

KINDS OF ACCELEROMETER

The two kinds of basic accelerometers are:

1. ANALOG ACCELEROMETER

At times Inputs and output readings also matter especially when it comes to determining the kind of accelerometer that needs to be placed on a certain object. If the output is digital then a digital accelerometer must be placed and vice versa. The main feature of this accelerometer is that the output tends to change when there is even a slight change in the input.
The most common type of this accelerometer is used in airbags of automobiles, to note the sudden drop in the speed of the vehicle and to trigger the airbag release. Even laptops are now being equipped with accelerometers in order to protect the hard drive against any physical dangers, caused mainly due to accidental drops.

2. DIGITAL ACCELEROMETER

The digital accelerometer is more sophisticated than the analog. Here the amount of high voltage time is proportional to the acceleration. One of its major advantages is that it is more stable and produces a direct output signal. Accelerometers are now also used in aerospace and many military applications, such as missile launch, weapon fire system, rocket deployment etc. Many a times these accelerometers are used to protect fragile equipment during cargo transportation, and report any strain that might cause a possible damage. Some companies have also managed to develop a wireless 3-axis accelerometers which are not only low in cost but are also shock durable. This 3-axis accelerometer has sensors that are used to protect mobiles and music players. Also these sensors are used in some of the devices used for traffic navigation and control.

New Line up of Cars Relies on Microsoft

A recent study conducted by the Center for Automotive Research (CAR) revealed that automakers are working together in small clusters to gain faster communication about their upcoming innovative cars. In order to do so, they use different information channels like web conferencing and other ways to effect live conversations through the Internet. By doing this, the manufacturers can secure the quality of product and customer awareness in a snap.

The study is entitled “Key Factors that Enable Product Development: An Investigation of Creating ‘Great’ Products”. According to said study, the automakers are demonstrating greater passion by turning to collaborative product development (CPD) technique through the help of Microsoft solutions. They are adopting these solutions to serve as catalyst to gain more advantage in the automotive world.

PSA Peugeot Citroën, for one, has worked with Microsoft Corporation to implement a Microsoft Office Enterprise Project Management solution. Due to this, information is shared hassle-free.

Consequently, Nissan Motor Co. Ltd. has also upgraded to Microsoft Office Professional Edition 2003 and the Windows® XP Professional operating system, along with Microsoft Office Outlook® Web Access and Exchange Server 2003. With this change, Nissan is expecting to maximize productivity at the same time save at least $135 million in the coming years. Nissan will also adopt Microsoft Office Enterprise Project Management in Spain. This is for a Design Change Collaborative Management platform for Nissan auto parts and automobiles. Microsoft technology is aiding Nissan to improve efficiencies in the entire process of complex planning, coordinating and monitoring vehicle manufacturing.

Patty Dilger, national sales director for the U.S. Manufacturing Industries at Microsoft, said “The auto industry is competing globally against an ever-increasing wave of nameplates. If an OEM expects to succeed, it must stand out with innovative cars developed through globally collaborative means that pull the consumer into the design process. By employing easy-to-use Microsoft solutions — from shared Web sites designed for collaboration to project-management tools and a whole range of Web-based methods for direct communication — the auto industry is deploying new ways to work together.”

Microsoft solutions are maximizes management and accelerates productivity. This is the focal reason why more and more automakers are turning to them for a rewarding collaboration.

Used Auto Parts

Used auto parts not only include car parts but also trucks and other vehicles. There are many websites that sell and buy used auto parts. These business firms salvage what they can from junkyards and improve on the quality of that part before selling it. If a person is interested in selling used auto parts then it is advisable to start the business on-line so that the seed money required for the business is less compared to any business that is initiated in the normal market.

The United States of America produces so many cars in a year that it is difficult to recycle every part that is produced and the junkyards have started to pile up. The used car parts market is very big in the US and is cluttered with useless parts that people try to sell. Recognizing and differentiating between useful parts and the useless ones is a skill that is required in this business.

Numerous salvage yards buy used automotive parts and usually purchase the sheet metal of the body and late model trucks or cars with usable parts. This means that almost all salvage yards owners are interested in buying automotive parts that are in working condition.

Used auto parts come in many varieties and the quality of a used auto part can be judged according to its age, the make, whether it was still in use, and according to the wear and tear that it has withstood. Many gas stations sell used auto parts but the quality of these parts may not be very good. If a person is interested in buying and selling used auto parts then a salvage yard can provide the seller or the buyer with myriad choices.

There are retail outlets, online stores, mechanics and salvage yard owners who readily agree to buy or sell used automotive parts to anyone who is interested. A simple garage sale can also be a solution for selling or buying used auto parts.

Ford Focus Fuel Cell Vehicle Hits Woodward Dream Cruise

Ford makes one great move as it graces one great event. Recently, Ford Focus Hydrogen Fuel Cell vehicle amazes over a million spectators in this year’s Dream Cruise. Said event was held in Birmingham, Michigan last Saturday, August 19.

Woodward Dream Cruise is a prestigious annual event of car culture. This event is the largest among car celebrations. It attracts millions of spectators as well as famous car manufacturers. In this 12th Woodward Dream Cruise, Ford made an on the road and on display exhibit to put on show its enormous fleet of fuel cell vehicles.

Due to the cost of fuel cell technology, it is deemed that cars such as Focus can be valued close to $1 million. It can be the most expensive car in the Dream Cruise. This is because Ford Focus parts are quite costly and classy. The car looks like sedan, the main difference lies on what is tucked under the floorplan which is the hydrogen fuel cell and auxiliary energy system. The trunk also carries the renewable hydrogen fuel.

Ford Motor Company is operating 9 hybrid hydrogen Ford Focus Fuel Cell vehicles in California. It is one of the 7 cities which Ford has planned to do testing on fuel cell technology. Ford’s fleet is composed of 30 fuel cell vehicles that can mount up more than 180, 000 miles.

Mary Ann Wright, director of Sustainable Mobility Technologies and Hybrid Programs for Ford Motor Company, said, “the engineers who work on the Focus FCV work hand in hand with those developing our gasoline hybrids. The knowledge we gain by engineering these cars not only benefits our expertise in innovative fuel cell propulsion technology, it also will help us deliver even better gasoline hybrids in the near term.”

Ford Focus Hydrogen Fuel Cell vehicles represent the devotion of Ford to advancing alternative-fuel in today’s generation. In fact, in the next decade, said alternative is expected to be viable in the automotive market.
