Used Foundry Networks Hardware Remains in High Demand

“In recent years, the trend towards used networking hardware has continued to surge. Drawn by the lure of lowering operation expenses, and the relative durability and extended useful life of second-hand IT equipment, a significant majority of IT professionals are turning to the secondary market for their technology demands.

According to a recent CIO survey, 77% of companies currently use refurbished equipment to run their networks. Many reported that the incremental performance advances of new technology rarely justified the capital outlay required to purchase hardware new. In addition, many companies sited the compatibility with existing networking equipment as a major consideration. With projected sales of routers to service providers expected to exceed $5 Billion in 2006, the market for refurbished IT hardware looks to gain significantly.

Foundry Networks is poised to benefit from this increased demand. According to a Dell’Oro report published in Q106, Foundry ranks number 4 in a total market share of over $3,659 Million, an improvement from the previous quarter. In addition, Foundry ServerIron application switches rank number 1 in the worldwide market share for total port shipments and Gigabit Ethernet growth, and are the best-selling content switch and server load balancing solution on the market. With an industry-leading 90% growth over the year 2003-2004 and the price/performance ratio of Foundry Products, it’s no surprise that the demand for used Foundry Networks has increased in kind.

As companies outgrow their existing network hardware, products like the ServerIron become readily available on the secondary market. For emerging companies looking to bolster or upgrade their network, many are looking to Foundry Networks products for their investment protection and full-feature set. With newer models being acquisitioned all the time, buyers in the secondary market are constantly gaining access to newer technologies at bargain prices. With almost 50% of CIO’s survey saying they expect to increase their spending on used gear in the next 18 months, it stands to mean a significant increase in the market for Used Foundry Networks products.

Keep Your Peace Of Mind With A Vehicle Tracking Device

A vehicle tracing system is a great device for security and productivity. This is used by both individuals and corporations to keep track of their vehicles. You can typically get a discount on auto insurance from having a vehicle tracking system on your car. This is because with a vehicle tracking system, your car is more likely to be recovered than without. This ensures that your damages will be much less expensive to repair if any repair is needed at all. Insurance companies like this fact because they will not have to pay out large sums of money in case of auto theft. Individuals like this because they will be more likely to have their vehicle back. Even with insurance, the amount of money you get for your vehicle if it is stolen usually does not account for all the money you put into it. Having a car stolen can be a very frustrating and expensive experience that is not worth it in the long run.

A vehicle tracking system is also used by corporations. Not only is it a good security measure for anti theft, it is a good way to check on productivity of drivers. For a company that has a fleet of vehicles security is very important. This is true for both the vehicle and the driver of the vehicle. A company can track where a vehicle is at any given time to see if the truck is being used somewhere it is not supposed to be. If it is very much off course, the company can contact the driver to see if there is a problem. It is also good for productivity. Because the company can see where the vehicle is at any given time, they can better keep track of their merchandise and their employees. If a driver is continually going off route, they may be running personal errands instead of doing the job they are supposed to be doing. Also, if a driver is lost, someone at the control center will be able to give them directions on how to get to their destination by seeing where they are and where they need to be going.

Metal Detectors For Treasure Hunting?

A metal detector is a portable electronic device which penetrates the ground magnetically in order to find traces of metal. This metal could either be discarded pieces of aluminum or valuable coins, jewelry and other buried treasures. Part of the appeal of metal detecting is this unknown factor, keeping amateurs and professionals on a constant scan for new sources of metal and more promising locations. These devices can usually penetrate sand, soil, wood and other non-metallic substances, making most areas fair game for treasure hunters.

Some metal detectors can discriminate between various metals, allowing users to decide if a particular discovery would be worth digging up. A significant percentage of hits are indeed pieces of metallic trash or discarded building materials. Part of the appeal of this hobby, however, is discovering a lost class ring or a piece connected with local history. Some professional treasure hunters use very discriminating detectors set only for valuable metals, but hobbyists tend to explore even the less lucrative hits.

Metal detectors are electronic devices that are used to find traces of metal usually from the ground, a person, or cargo. This metal could be anything from discarded pieces of aluminum to buried treasures. These devices can penetrate sand, soil, wood and other non-metallic substances.

Most metal detectors, hand held, and the walk-through ones at the airport utilize a field-disturbance detector. That is a fancy name for a simple concept. When a conductor passes through a magnetic field, a portion of that magnetic field is disturbed, distorted and reduced. That reduction in the magnetic field is related to a small amount of current that is induced or created in the conductor.

You can do the same thing by jumping rope with a piece of wire instead of the rope. As the wire cuts through the earth’s magnetic field, a small amount of electricity is generated at the end of the wires.

Electromagnetic induction is the creation of an electric field by a fluctuating magnetic field. The electric field may be produced, according to Faraday’s law of induction in two ways: by the motion of a conductor cutting across the lines of magnetic flux of a magnetic field or by a change in the magnetic flux passing through a coil immersed in a non constant magnetic field.

Making My Own Metal Detector!

Mention the words metal detector and you’ll get completely different reactions from different people. For instance, some people think of combing a beach in search of coins or buried treasure. Other people think of airport security, or the handheld scanners at a concert or sporting event.

A basic metal detector consists of an electronic box and battery case on one end, with a brace or handle for the operator’s arm. An insulated wire wraps around a telescoping shaft and into a round plastic disk called the coil. This disk comes off the shaft at an angle which allows it to be held parallel to the ground. The operator straps on or grips the electronic box and turns on the power. The idea is to slowly sweep the coil end over the ground until an electronic signal is heard. This lets the user know that some metallic element is buried directly beneath the area swept by the coil.

Metal detectors work on the principal of electromagnetics and their effects on conductive metals. There are actually two separate elements in the coil of a typical unit. One is a high-powered coil of metal which uses the battery power to generate a penetrating magnetic field. This coil is called the transmitter. As the elecromagnetic field enters the ground, anything metallic will become charged with magnetism, similar to a paper clip become magnetized after contact with a standard bar magnet.

Michael FARADAY observed (1831) that when a magnet is moved through a closed coil of wire, a current is induced in the wire. The direction of the current flow is such as to create a magnetic field opposite in direction to that of the change in the field produced by the magnet. Faraday then replaced the magnet with an electromagnet.

Two coils were wound close together, the first being connected to a battery and the second to a galvanometer, which measures small currents.

Metal detectors must also be adjusted to eliminate false positives generated by natural deposits of metal in the soil or sand itself. Most units allow users to change the sensitivity of the coil in order to cancel out the background clutter. Some other uses of metal detecting technology include security inspections at airports, government buildings and other public places. Construction crews and woodworkers also use hand-held metal detectors to find dangerous nails or other metallic debris in reclaimed building materials and trees.

Closed Circuit TV: Video Surveillance to Protect Our Security

We in UK are quite accustomed to moving around under other’s surveillance than a general person in many third world countries.

More than 400,000 cameras are always monitoring us in a car park, station, shopping complex, on our way to office or may be even in our private spaces, unwanted. General people are day by day supporting its presence to fight against internal and international crime.

In post 9/11 scenario, CCTV cameras are being installed more and more round the corner primarily for better and entrusted public security.

This CCTV monitoring is widespread not simply in our own country. Recorders are being installed on the Trans Europe Motorway from the Greek border through Turkey towards Ankara. This is covering a distance of 700 kilometres. This huge project supports over 1,400 camera inputs and 480 audio channels and it is probably the largest networked recording Security surveillance system contracted until today.

Fifty wi-fi enabled CCTV cameras are installed across central London that may revolutionize the police patrolling system within 18 months of trial period. In recent future, police will be able to track a suspect from a handheld device as the system can be controlled locally within that network coverage.

One thing must be mentioned here that, general people may also use such technology as IFSEC hand-held PDA applications provide security personnel with the ability to view both live or recorded camera images from any installation, located anywhere in the world.

However, this may end up the age long debate that these closed circuit TV cameras only can record a crime in progress. Now the police persons will have more opportunity to reach the spot and take necessary actions on time.

Future really holds hard for drug dealers, peddlers, and an easy finder of parking spaces for citizens.

Nevertheless, currently there are no cost effective night vision systems available for object identification for distances from 150 metres to 2000 metres. On the other hand, active infrared systems have a narrow field of view that makes navigation and orientation difficult.

Still there are some cameras available in the market that can serve the purpose as good. These cameras are ideal for covert applications since they utilises a laser light that operates below the visible spectrum to illuminate the target area.

However, it all depends on the needs of the users.

There is a good lot of software like EVIS that can provide tailor-made solution for the end users and is flexible enough to meet all custom requests by the use of a modular system.

Is there any harm in taking protection beforehand if the users are conscious of their social limits and responsibilities! Time to decide.
