Electronic Embedded System Design – Important Feature Of Online Electronics Magazines

The world of electronics is witnessing a revolution in the way products are conceived, designed and implemented. The ever growing importance of the web, the advent of microprocessors of great computational power, the explosion of wireless communication, the development of new generations of integrated sensors and actuators are changing the world in which we live to perform. The online electronic magazines provide every information about the ongoing trends that take place in the designs of electronics including those in Electronic embedded system design. One well designed and planned magazine that I like much is Electronics For You; it provides every possible knowledge about ongoing trends in electronic designs. It is a boon for all those associated with electronics trade.

Electronic embedded system design is a routine segment of this online electronics magazine. The overall goal of electronic embedded system design is to balance production costs with development time and cost in view of performance and functionality considerations. Manufacturing cost depends mainly on the hardware components of the product. Minimizing production cost is the result of a balance between competing criteria. If one considers an integrated circuit implementation, the size of the chip is an important factor in determining production cost. Minimizing the size of the chip implies tailoring the hardware architecture to the functionality of the product.

As the complexity of the products under design increases, the development efforts increase dramatically. At the same time, the market dynamics for electronics systems push for shorter and shorter development times. It will be soon imperative to keep to a strict design time budget, no matter how complex the design problem, with as little as six months from initial specification to a final and correct implementation. To keep these efforts in check and at the same time meet the design time requirements a design methodology that favors reuse and early error detection is essential. We expect the majority of high volume platforms developed to be programmable either at the logic/interconnect level (e.g. via FPGA) or using software.

Both reuse and early error detection imply that the design activity must be defined well, so that all phases are clearly identified and appropriate checks are enforced. To be effective, Electronic embedded system design methodology that addresses complex systems must start at high levels of abstraction. The professionals of most companies, engaged in Electronic embedded system designs and IC design, are familiar with working at levels of abstraction that are too close to implementation.

It is must to know the latest updates in Electronic embedded system design practices to keep the production cost and the product cost bare minimum; and efy like electronics web-portals may be the good source to get all the information within seconds.

What Are The Advantages Of Electronic Locks

Switching to electronic locks has become a great option for many people. Keeping your valuables and important paper work safe is a top priority. Electronic locks give you the peace of mind you are looking for both for the home or the small business owner. Understanding how electronic locks work will help you make your decision regarding which one to buy for your purposes.

Electronic Locks Offer Extra Security

The new trend in electronic locks is being led by large security companies who are now able to offer safety systems that include a direct connection to the local emergency support system. They go way beyond the lock and key system that has been used for years, to offer even more security, as well as, ease of use. The new systems are able to offer your more security and more protection.

These new systems offer a level of security that heretofore has not been available. Electronic locks work using an electrical current. There are a variety of systems. Some are attached directly to the lock, while others are connected to a control system located elsewhere.

The Magnetic Lock

There are two major types of electronic locks on the market. One is the magnetic lock, or more popularly referred to as a mag lock. These locks use a magnet that is placed on the door frame that engages the armature on the door. The magnet holds them tightly together. This is a very easy lock to install and it is difficult to break into. They do require electricity to work and if the power source is disrupted the lock will not work.

The Electric Strike Lock

The electric strike lock is the one most often used in the buzz in types of systems. Instead of a standard strike, an electric strike is used that is hooked into an electronic mechanism. There are a variety of types of electric strike locks. Some are easier to install than others and some will work regardless of the availability of current and some will not.

Verification before Entry

The keystone of electronic locks is that they require some form of confirmation that you are allowed to open the lock. A numerical code is used most often that requires the person entering to type in the correct sequence of numbers in order to gain access. Once the code is entered correctly the lock will disengage.

Another method of verification used is a key card or pass card that must be scanned or swiped to gain entrance. Many businesses use this type of electronic lock to enter offices, elevators and garages.

A third method that is growing in popularity is biometrics, which is a fancy name for fingerprint scanning, retinal scanning and voiceprint identification. Places where a high level of security is required most often use this type of electronic lock.

Now that you know what types of locks are available, you can begin to consider what type of lock will work best for you. These locks offer such an increased level of security for the average person; it only makes sense to replace the old fashion lock and key with an electronic lock as soon as possible.

Are Refurbished Or Recertified Electronics Safe To Buy

The term “refurbished” typically refers to electronics that have been spoiled and returned, then repaired and re-sold by the maker. But the definition is actually broader than that. Refurbish may never have been damaged to begin with. Some are simple returns and interactions. Some refurbished electronics are ready with new cases and batteries, so they externally resemble their new counterparts. It varies by vendor and manufacturer, so be sure to check out the detailed policies before you buy.

Another word may comes in mind is “re-certified.” This usually means that the electronics equipments have been returned or repaired, then tested and settled some kind of guarantee. However, all refurbished products have to be experienced before they can be sold, too. Also, some refurbish have brilliant warranties, while some re-certified products have terrible ones. In general, “recertified” and “refurbished” can be used interchangeably. What matters most is that the creation in question has a good warranty.
This means that they can’t be measured an “investment,” because they lose value over time. To take the car example further, most cars lose 25% to 40% of their value within the first two years. However, a two-year-old car will have lost almost none of its utility. This is why it’s best to let someone else buy new, pay that 40% extra, then sell to you. The same logic applies to laptops and other classy electronics. Very few of us need the latest, most powerful components, and those of us who do can usually stand to want the few weeks or months it takes for the first refurbished models to show up.

But we should be careful about buying electronics used. Laptops don’t have the same lifetime as cars. Refurbished is an improved choice, because of that all-important contract I keep talking about. In general, you should look for a warranty of at least a month or two, to make sure the product doesn’t have any clear defects. Preferably, the warranty should expand beyond that. To once again use Apple as an example, their refurbish come with the same one-year warranty as their new products yet another cause to buy refurbished.
Huge deals can be found in refurbished or recertified stuff. But, you need to make sure that the item will robust your needs. Make sure to study in and do some research on both the item you are thinking of purchasing and the seller. A trustworthy seller will offer a return if the item does not work when you receive it and most times offer some sort of short term warranty. So, don’t be afraid of the words refurbished or recertified on items. They can be a great deal, a super deal, and save you lots of money if you research properly.
Conclusion:
A good tip if you’re thinking about buying a refurbished or recertified item is to ask if it comes with a warranty. Not all manufacturers offer this, but you should ask, and if they do, ask how long the warranty lasts. At the end of the day refurbished or recertified products can be good, you can get great bargains on items that may have little, or no defects. If it wasn’t for manufacturer’s refurbishing or recertifying their products, they would all end up on the trash heap. Buying these products is kind of like buying a recycled product, it is a good idea, and can become a speculation in the long run.

Computers, office equipment, mo bile phones, and many other business necessities are available both online and off-line, so you have many options to consider.

Tips for In-Store Buying

When shopping for electronics or computers at a local store, compare brand names, features and pricing carefully. Sometimes a low price means sacrificing the quality or features you really need. For instance, if you’re planning to buy a computer desk, consider the design of the desk and all its features. Does it have drawers or shelves to make organization easy? Does it have a pullout keyboard or a desktop keyboard? Also, consider the size of the desk and the quality of its materials (steel, solid wood or particle board).

When buying a computer, consider brand name, size of the hard drive and memory, as well as any pre-installed software it may contain. Avoid buying computers that have “advertising” menu bars pre-installed on the Windows screen. These tend to hang up often and are not worth the hassle although they are usually lower in price. Look for reputable brand names such as Dell, Pentium, Acer, and Compaq. Dependable laptops are available from these companies: Dell, Averatec, Compaq, HP Pavillion, Acer, Gateway, and IBM.

Avoid rebate offers. Rebates are often more trouble than they’re worth, and your name might get added to hundreds of mailing lists! Instead, shop around for a great value up front to get the PC or laptop that will meet your needs.

Refurbished Products

With refurbished electronics or computers, find a reputable company that has a good standing with the Better Business Bureau. Some companies will advertise refurbished items, but will not follow through with a guarantee. Before buying a refurbished item, check for a guarantee and do a little research on the company to find out if other customers were satisfied with the products and service.

What Are The Advantages Of Using Electronic Tilt Sensors In Off-road Vehicles

Off-road vehicles are designed to perform the most difficult tasks in often in the most extreme outdoor conditions. In industries like construction, forestry and agriculture, vehicles often have to navigate on uneven surfaces and slippery terrain whilst lifting and manoeuvring heavy and uneven loads. This can present difficult challenges for the drivers of these vehicles: for many vehicle operators, the chances of tipping or rolling the vehicle over are high, so obviously safety is a paramount concern. However, electronic sensing technology is now available which makes the vehicle drivers job easier and safer. As these electronic sensors can detect the vehicles operating condition and alignment, the safety of the operator is greatly increased.

Tilt Sensors Monitor the Safe Horizontal Alignment of Vehicles
Off-road vehicles often have to work in extreme conditions, where rugged terrain and heavy moving machine parts can quickly shift the balance of a vehicle. A shift in the dynamics of the vehicle or an uneven transfer of weight or dangerous alignment can cause hazardous conditions for the vehicle operator. Electronic sensors can help operators to monitor the horizontal alignment of vehicles. Tilt sensors can precisely detect even the slightest angle variation. Tilt sensors can give the driver accurate information about the exact road-grade angle, the boom angle, the platform angle and the crane-level angle. Armed with this important information, an operator can then take action to avoid a potentially disastrous situation.

Tilt sensors, however, need to sturdy and resilient. They have to be able to withstand the extreme shock, vibration, and all the harsh elements associated with outdoor use. Moreover they also have to be able to cope with direct exposure to chemicals, dirt, moisture, sunlight, and electrical interference. Therefore tilt sensors have been designed so that they are capable of resisting these elements and are able to perform in extreme environments. They are able to do so because of certain special design features like:

Compact housings rated for IP67 protection which encase and protect the electronics from chemicals and liquid ingress,
UV-resistant plastic and metal housings which prevent damage from exposure to sunlight,
Noise-immune technology which enables the sensors to ignore conducted and radiated electrical noise.
Outputs protected from short-circuits and overloads which eliminate damage during installation,
LHighly flexible cables, which are armoured to resist chemicals and perform at temperatures as low as 40 F.

Sensing technologies
There are two very different, yet highly effective sensing technologies that can be applied to verify the horizontal alignment of off-road vehicles: electrolytic tilt sensing and micro electromechanical sensing. (MEMS)

Electrolytic tilt sensing
Electrolytic tilt sensing technology can measure the tilting of a reference plane in two axes, by measuring the tilt angle with reference to the earths ground plane, using an accelerometer. At the centre of the sensors core are measuring cells surrounded by fluid or liquid. These measuring cells monitor ant change in the liquids conductivity to detect angle variations and deviations.

MEMS sensing technology
The second technology is micro electromechanical sensing (MEMS). When a vehicle lifts or tilts, the movement is transferred to the beams of the sensor that deflect to take the inertial force of the mass. The change in capacitance is proportional to the tilt of the sensor, which is ultimately then converted to a change of voltage and transferred as an analogue value to the driver of the vehicle. The use of MEMS sensors incorporating this technology are better suited to applications where a single-axis wide tilt angle (90) and lower precision (1) are needed.

Electronics for Marine Navigation

Navigating on the open water away from land has always been challenging and very exciting. Boating can be a very rewarding experience provided your vessel is equipped with the required tools to ensure your safety. Good quality marine navigation electronic equipment on board aids easier, faster and safer navigation.

It is recommended to make sure that, the boat is equipped with certain marine electronics. The minimum requirement for safety is to at least have a VHF Marine Radio and a compass before leaving the shore. Other desirable electronics include a GPS plotter, fish finder or depth sounder,radar, and auto pilot. Other more sophisticated but nice to have items include an Automatic Identification System and a networked navigation system

Marine navigation electronics equipment operation and uses are discussed below:

Auto Pilot: It is a highly recommended tool for mariners set to go on a long voyage. Auto Pilot helps to steer the boat automatically and thus, relieves the person at the helm from fatigue. Auto Pilot is of great aid for those that troll while fishing as it controls the boat direction automatically, allowing the captain to join and enjoy the fishing. This tool is very helpful, as it allows to save fuel by maintaining the vessel on a steady heading.

Fish finder: Those who fish for pleasure or hire enjoy the help provided by a good fish finder. The fish finder uses SONAR for its operation. In general, the sonar operates by transmittig a signal down trough the water column until it hits an object with mass, sufficent to return a signal to the device, thus drawing an image on the screen. Thereby, showing the depth of the fish in relation to bottom structure. If a fish finder is not desired or needed then a depth sounder with a digital readout is ample and less expensive.

Automatic Identification System: It is considered an important electronic tool for marine navigation. It provides other boats with your vital information as well as their information to you such as the exact position of the boat, longitude and latitude, Time stamp, Rate of turn, Course over ground etc. While the boat under way AIS shows the above information every 2 to 10 seconds, whereas when the boat is anchored, it shows the information after every 3 minutes. Apart from providing the above-mentioned information, it also provides information about other boats or ships concerning their dimension, location, and type of the boat or ship. It is the best electronic tool for collision avoidance.

EPIRB: The Emergency Position Indicating Radio Beacon (EPIRB) also known as distress radio beacon is a transmitter, which helps rescue services to locate boats in distress. The transmissions are rebroadcast from satellites around the world to the various rescue services. Watercraft operators wishing to have an EPIRB must now use a digital 406MHz unit. The International Copas-Sarsat Satellite System stopped monitoring for all but 406MHz signals for distress alert and position data for rescue operation throughout the world..

GPS Plotter: The GPS system now takes over the duty of the old Loran navigation system. GPS signals are broadcast from those satellites worldwide, that are maintained by the USA . GPS can be read in digital or map format. The preferred method is on a plotter that is loaded with digital maps of the area you are boating in. Most new VHF radios now have the capability to broadcast your location with a distress signal if connected to a GPS

Choosing the Right Keypads for Ruggedized Electronics

Not all electronics are used in homes or office environments where conditions are carefully controlled. Ruggedized electronics are designed for use in harsh environments and have to be designed to function in extreme conditions. Many keypad designs won’t survive these situations which is why manufacturers prefer molded keypads made of silicone.

The Need For Ruggedized Electronics

The military is one of the leading clients needing equipment designed to survive harsh conditions. With operations all over the world, electronics need to remain reliable in scorching desert, humid jungles, or freezing arctic conditions. Packing the equipment in a protective case between uses is not an option. The case adds weight that a soldier needs for other equipment, plus there may not be time to carefully pack the equipment away during an operation.

Civilian clients aren’t much less demanding than military ones. Their ruggedized electronics might be used on field projects where they are exposed to environmental extremes, industrial area where heat and dust are common, or laboratories with corrosive chemicals. This equipment needs molded keypads that won’t be fouled by contaminants or destroyed by environmental factors.

Rugged Coatings For Rugged Electronics

Custom silicone keypads have a number of properties that make them idea for ruggedized electronics. The flexible material means the material won’t fracture if struck by a hard blow. The one-piece construction of the unit resists liquid and gas contaminants getting into the delicate electronics. Silicone has inherent resistance to a number of chemicals and the molded keypads can be customized to fit any size or shape needed.

The inherent capabilities of silicone custom keypads can be enhanced by a number of coatings. Abrasion resistance means the keys won’t wear down and the markings won’t wear off even under heavy abuse. Chemical resistant coatings enhance the silicone’s natural resistance, guarding it against petroleum products and oxidizing chemicals. Conductive coatings protect the electronics behind the molded keypads, keeping them working over a million activation cycles and shielding from EMI.

Tough Solutions Even For Easy Environments

Although the average household may not pose the same challenges as military or industrial clients, consumers will still appreciate the durability of custom silicone keypads.

Liquids are one of the worst enemies of consumer electronics. A spilled drink can spell disaster for electronics, but using molded keypads allows the liquid to slide right off. This doesn’t make the entire component water tight, but it adds some water resistance that customers will appreciate.

Kids are rough on custom keypads even when they aren’t spilling on them. Whether it’s the TV remote, controls on a child’s toy, or some electronic device the kids shouldn’t touch (but you know they will) molded keypads stand up to the abuse. The durability they provide can add years of life to a product and build a company’s reputation for building reliable products.
