Cellular Router Enables 3G - GPRS Connectivity To Industrial Equipment by Leon Mengot
Now, thanks to the Connectport WAN VPN, a next- generation cellular router designed to connect RS232 or Ethernet devices in-the-field directly to an internet facing PC, remote sites that previously could not connect to the internet can be networked and web connections made from mobile devices on... Extensive routing functions including NAT, PAT (port forwarding) and VPN gives the unit the flexibility to perform in any way the system architecture dictates. ... A built-in 4-port switch allows four Ethernet devices to connect directly to the Connectport WAN VPN without the requirement for an...

Embedded DVR by Max Bellamy
In most surveillance operations using a DVR, the commonly used method is to link the DVR card to a computer containing the software. This has serious limitations in the event of a virus attack or power failure, because the surveillance system could be thrown off gear. ... In such a system, the storage device is often a replaceable hard disk drive. ... These DVRs are compact and take inputs provided by camera located in different parts of the automobile. ... Specially developed embedded DVRs have in built features like impact resistance, shock & and vibration resistance are now found in...

Expansion Cards Part 1: (of a 3 part series) by Jason Kohrs
PCI The expansion slots available on motherboards allow for a variety of upgrades in a computer system, but matching the appropriate card to an available slot needs to be addressed before making any purchasing decisions. The most common types of expansion cards for modern computer systems can... The letters “PCI” stand for Peripheral Component Interconnect, and is the term used to describe a bus that connects components directly to the system’s memory and to the system’s processor through the “frontside bus.” When discussing communications on a motherboard, the term “bus” has nothing to...

New Laptop Technology You Need To Know (Before Buying Your Next Laptop) by Titus Hoskins
Laptop or notebook computer technology is advancing at a blistering speed. Ferrari fast. So fast that by the time you purchase your new laptop, it's probably already obsolete or out of date. A sobering thought considering the hefty prices you have to pay for a high-end laptop. ... Of course, in an ideal world, all the data in your computer should move thru just one BUS - however, most experts agree it's not likely to happen unless we start over and build a computer system from scratch. ... Keep in mind, the major difference between a 32-bit and a 64-bit system is the amount of memory...

System Buses Explained by Alan Ogden
System Buses Explained I don't know about you, but I for one, despite thinking to myself that I had it all under my grasp always get confused when thinking about the array of buses in a modern computer. Bandwidth of the CPU, memory, AGP plus new technologies such as Hypertransport always leave... The AGP bus was a 32bit bus like the PCI bus, but it operated at 66MHz giving it a maximum bandwidth of 266MB/s. ... # Expand the bandwidth of the bus - Server motherboards, especially with the prevalence of SCSI hard drives requiring more bandwidth than the PCI bus can transfer, have moved to a...

Thermal Plants by Lalit Bansal
SWITCHYARD and GENERAL SIGNIFICANCE Electrical energy management system ensures supply of energy to every consumer at all times at rated voltage, frequency and specified waveform, at lowest cost and minimum environmental degradation. The switchgear, protection and network automation are... Operating Voltage 230 V Rated current 2000 A Minimum short circuit current in bus bars 40 KV Minimum phase to phase clearance 2.5 M Number of horizontal levels of tubular bus bar/flexible bus bars 2.0 M Height of tubular bus-bar of first level above ground 6 m Height of tubular bus-bar of second...

RFID: When You Don't Even Know It's There by Andy Reed
RFID (Radio Frequency ID) enables wireless data capture and transaction processing. Our last column discussed proximity applications, used primarily for access control. This time, we'll take a look at what are broadly defined as vicinity, or long-range applications, used for product tracking,... Instead of the traditional librarian checking out a book - older readers will remember the card slipped into a pocket inside the cover, on which you could read previous borrowers' names hand-written along with the check-out and return dates - or the bar-code system that replaced the cards a...

3D Modeling in Transportation Flows by Lance Winslow
We need to borrow the technology that the military uses for the Battlefield 4D holographic simulations in the Net-centric Warfare Battlespace and transfer this technology to help the DOT and DHS predict how to keep the distribution systems are moving in our Nation in real-time. ... By using such a system and GPS tracking of trucking, cargo containers, ships, planes (using Lockheed’s global system and the FAA system) we can predict under utilization points and times and fill them while alleviating times and areas with choke points causing a loss of productivity to our citizenry, small...

Local Area Networks - Computer Networking by Michael Cooper
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need... The question now is you have a standard and you have a connection now how do you manage the system to run flawlessly?” Networks use protocols, or rules, to exchange information though a single shared connection.

HIPPA Goes Mobile and Wireless for Hospitals and First Responders by Lance Winslow
It appears we need to further streamline health care and HIPPA now in effect is quite a nightmare trying to comply with and implement without making a mistake and possibly being sued as the trial lawyers testing the law. The Malpractice insurance rates may go up again. ... Some lawsuits, but in the end although the problems will be quite burdensome and much will be fought by the employees who do not like it as with any new system, innovation or change due to resistance of the status quo. ...
