What one refers to, when they use the word GPS tracking is the global positioning system receiver that they use to determine the precise location of the person and vehicle while it is moving, and so, one can continuously track their location. The beauty of this system is that it uses a GPS antenna (of about 10-15 feet) to collect GPS data from specific satellites orbiting the earth which is then sent to GPS tracking company’s servers for processing in real-time.This GPS tracking system was initially developed and implemented by the United States military with the set up of the 27 Earth-orbiting satellites, and now has been opened to the public for use. Several companies now use this system that is in place to provide GPS services to organizations that are in need of such systems.

Interestingly, depending on the time taken by the GPS satellites to send signals back to earth, the GPS receiver is able to calculate its position. However, even a small clock error can result in a large error as it is multiplied into the speed of light as this is the speed at which the signals are sent to receiver. So, three of four satellites are normally used to determine the time accurately.Some of these companies also provide gps fleet tracking services for transportation companies that have an entire fleet of vehicle transporting materials and for whom, most importantly, time is money.

Transportation firms have come to depend on GPS tracking system solutions for quality customer service and fleet efficiency. In order to satisfy your clientele and provide quality products and services, we recommend the latest GPS tracking hardware such as the Locator 2000 Trailer. The following is an inside peak at this innovative product available through Global Tracking Communications, Inc.

Specifically engineered to monitor tractor trailers and heavy equipment, the L2000 Trailer reports tracking information from trailers (tethered or un-tethered) and heavy equipment. When set to offer 15-minute updates without outside power sources, the fleet GPS tracking system can track for 30 days. However, when updates are extended to longer periods of time, battery life may extend to several months. Managers and other users receive location reports, history logs, trail routes and other reporting options.

If you’re interested in maximizing your sales and reducing your losses, this cell phone GPS tracking system can help you achieve your goals. By monitoring your fleet resources daily, you will protect your investments and guarantee accurate pick-up and delivery times.

Keeping the power going to your commercial facility is critical to your survival. But if switchboards, transformers or ITE circuit breakers fail, this is all at risk. If your supplier has the part on back order, you are normally stuck until they are able to get a replacement in stock. This can have a crippling effect on your business.

One solution to this problem is to rent electrical equipment from a leading supplier like RELECTRIC. It’s a fast and easy way to get your system up and operational, and all products are pulled from the company’s main inventory and have the same one-year warranty as products like Cutler hammer breakers. For more information on rental equipment from RELECTRIC, please visit www.relectric.com.

A downhole transducer goes through extreme environmental stress when it is deployed into an underground environment. This means that it needs to be specially designed to withstand the rigors placed on it. Here are a few examples of the environmental factors that require specialized transducers:

Pressure: The purpose of a downhole pressure transducer is to take readings of gas and liquid pressures below the Earth’s surface. Depending on what is being measured and how deep it is underground, these pressures can be quite substantial. There will likely also be a maximum operating pressure that a sensor can take before it is unable to function.

Temperature extremes: Depending on its usage, a downhole temperature probe can be exposed to a range of temperatures from 40 degrees below or lower to well over 400 degrees for extended periods of time. In fact, the temperatures that a probe goes through in one locate can fluctuate wildly as well. Some applications such as measuring well bore fluid temperature in oil tools, engine in-line fluid or air/gas temperature sensing can require the ability to measure temperatures more than 300 degrees below zero or over 500 degrees.

A multiport serial card is installed in on the ISA or PCI bus of a PC. The card is helpful to the user because it provides many serial ports in the place of one, and so many computer users now use numerous external devices, such as video cameras, digital cameras, and scanners. Additionally, others use work-related equipment such as video-editing applications, faxes, or special printers for desktop publishing. At one time, serial cards were mainly used for connecting up many modems to serial ports. Today, several modems can now be built into an internal card. For this reason, multiport serial cards are not used as commonly as they were before.

Each multiport card has a number of external connecters (DB-25 or RJ45) so that one may connect up a number of devices (modems, terminals, etc.). Each such physical device would then be connected to its own serial port. It then requires a USB serial adapter.  There are dozens of different serial ports and adapters that can be used for various applications. For example, a video splitter requires one set, but a scanner or fax would require an entirely different set unique to those machines.

Finally, because there is limited space on the external-facing part of the card, sometimes there is not enough space to hold all the serial port connectors. In this case, the connectors may be on the ends of cables that extend from the card. Or, they can be on an external box that is connected by a cable to a multiport card.

One of the ways that many non-gamers have come to recognize gaming PC is by the case.  While not all computers configured for gaming can be so identified, there are quite a few models that sport far flashier cases than one normally finds on more mainstream computers designed for everyday workloads.  In particular, companies like Digital Storm that focus solely on building gaming computers tend to offer cases with eye-catching features such as clear panels and accent lighting.

One important thing to note is that these cases are more than just flashy. They are also built to be functional.  While you’re generally getting the best of the best when you order custom gaming computers, the specs might not be good enough for the hottest games down the road. The cases are thus generally built to allow for easy expansion. They also have to provide ample cooling for the high-end components.

The thrill of having a sleek new laptop can quickly change to regret when a disappointed owner realizes that the new computer lacks a standard serial port. There is an easy solution though! The user can purchase a serial card that will provide a standard DB9 serial port for nearly any laptop. (As with all electronic products, before making a purchase, confirm with the manufacturer to be sure the product will work with your laptop.) An example of this type of card is the PCMCIA Serial Card. Most laptops today come with a USB Serial Port, but there is no set solution to connect a CNC machine via a laptop using this USB technology. Ideally, users need a USB Serial adapter that works under Windows 2000 and XP.

An ideal solution is using a RS-232 serial PCMCIA card. These can work with any laptop to add additional ports for various portable systems. They function like standard COM ports and can be left in the computer at all times. The small size and the fact that the card itself can be left inside the computer at all times is convenient and practical for use with portable systems. To connect a laptop to any CNC, purchase a PCMCIA card along with an RS232 extension cable. Many users wonder how an RS232 connector can be soldered to an USB extension cable—but the differences in design between RS232 and USB technologies don’t yet allow for this.

The Internet has changed the way the many people experience entertainment. One of the many popular additions to our lives is the advent of free radio stations that are streamed online. This allows listeners to experience a much wider range of music than they would hear on their local radio waves, as well as giving them the ability to find very specialized stations that better cater to their tastes. However, things haven’t been entirely smooth for Internet radio, particularly in terms of royalty fees.

Radio stations that stream over the Internet have never been the most profitable business plan. Many are actually labors of love for the owners. These stations were able to exist because the from 1998 to 2005, the royalty rate was only $0.000768 per song. However, in May of 2007, the United States Copyright Royalty Board approved a rate increase for royalties paid to stream music online. This decision is currently under appeal, as it would force the closure of a large number of stations, or at the very least a major upheaval of their business plan. According to the revises rates, the owners of affected stations would be required to pay as much as $2.3 billion in royalties this year. This number is actually four times the amount that traditional radio stations pay in royalties.

One plan that some stations are opting for is to switch to broadcasting from foreign territories that are outside of the jurisdiction of US Copyright law. In order to protest the proposed royalty rate changes, many online radio stations participated in a Day of Silence on June 26, shutting down their broadcast for the day. A bill known as the Internet Radio Equality Act has been proposed and has already been introduced to both the House of Representatives and the Senate. There are currently over a hundred co-sponsors in Congress.
