The Department of Defense’s (DoD) ambitious smartphone program may or may not reach its goal of providing advanced mobile communication devices to the warfighter, but it certainly has already scored one noteworthy achievement: creating stories for journalists. At last count, Google News has 300+ entries for “military smartphone.” Most of these stories report that the single biggest obstacle to smartphones deployment is security. Read more
In describing computer displays, what do the terms “transmissive,” “reflective,” and “transflective” mean?
Transmissive is the most commonly used means of illuminating a computer display. The display is lit up from the back. While this method is fine for indoor use, strong sunlight may overwhelm it, making the computer screen difficult to read.
Reflective method does very well in the bright outdoors. The computer is illuminated by the reflected light of the computer’s surroundings. The brighter the sun, the brighter the display. However, it does not do well in dim settings, i.e. indoors.
Transflective combines the transmissive and reflective methods of illumination. This gives the viewer the best of both worlds, enabling the display to be optimized for the greatest variety of environments.
Even though transflective appears to be the best method, it may not be the best for you. You need to consider your applications specific needs, including energy usage, heat generation, and issues such as compatibility with night vision goggles. Display brightness may also be affected by chemical treatment of the surface (anti-glare coating), viewing angle, contrast controls, and a host of other factors. For more information, see Are nits the only important rating for hi-bright display?
The initial purchase price of your rugged computer may only be a small part of the Total Cost of Ownership (TCO). Platform support, customization, integration, connectivity, and inadequate durability may make your “bargain” very expensive. Will your rugged computer be good for your ROI five or ten years from now or just for today?
Commercial Off the Shelf (COTS) products are attractive for the price and established supply chain. However, there is a fundamental problem buying mass-produced off-the-shelf items. New and upgraded products typically generate more profit than old ones. Corporations prioritize the overhead of product support for the greatest revenue earners, i.e. the new products. Support for older platforms is phased out. Read more
Los Angeles, CA (April 28, 2011) American Reliance, Inc. (AMREL) announced the launch of the ROCKY DB6 — the smallest, fully rugged handheld that can support standard Windows 7 and Linux Operating Systems (OS). Certified by independent parties to meet military standards for ruggedness, this compact handheld weighs less than two pounds.
“The military is pushing the envelope of connectivity out to the front lines,” explains Ron McMahan, AMREL’s VP of Sales. “They want ISR (Intelligence, Surveillance and Recognizance) data in the hands of the warfighter. This has created a need for a computer that can transmit large encrypted files in real time, operate in harsh combat conditions, and is small enough to fit into a cargo pants pocket. The DB6 is that computer.”
The key to the DB6 is the Intel® Atom™ Processor. More powerful than typical PDA processors, it consumes very little energy. Consequently, the lightweight DB6 can run the same OS and applications as a laptop, but with significantly longer battery life. This reduces logistical burdens in the battlefield and eliminates the need to modify standard programming for mobile devices. Read more
No. Life is not simple and neither is buying a bright monitor. Many factors besides nits can interfere with the visibility of a screen. Computer displays are usually protected by see-through shielding material (glass or plastic) on top of their displays. How this shielding is bonded to the underlying surface can have a huge effect on the amount of glare (reflection) that is created. Anti-reflective coating on the shielding material can also affect the overall illumination. Even the mounting of the internal components of the computer can affect the brightness. So, it is theoretically possible that a display with a high nit rating will be dimmer than one that has a lower rating. To be sure you get what you want, consult your computer professional.
The primary purpose of MIL-STD 810 is for “…generating confidence in the environmental worthiness and overall durability of materiel system design”(U.S. Army Developmental Test Command (DTC)). This standard establishes specifications and testing procedures for resistance to rain, shock, vibration, dust, humidity, salt fog, and extreme temperatures.
Some think of 810 as “the” rugged standard, which of course, is not true. Many other standards come into play, such as MIL-STD 461 for electromagnetic emissions or the Navy’s MIL-S-901D for equipment mounted on US ships.
MIL-STD 810 is sufficiently complex and multivariable, that it may be more appropriate to think of it as a set of environmental standards, rather than a single specification. This is especially true when evaluating compliance. It is quite common for commercial companies to claim that their product “meets” MIL-STD 810, when actually it only meets a small fraction of the specifications. Read more
In a recent posting (Network-centric Warfare: Dead or Alive ?), I wrote about the debate concerning network-centric warfare. In the wake of the “reorganization” and outright elimination of high-profile initiatives and programs associated with network-centric warfare, Defense vendors are anxiously wondering if it will persist as a central doctrine for transforming the military.
Clearly, the military’s obsession with connectivity is far from over. DARPA is actively working to overcome the military’s traditional anxiety about the security of distributed servers (Pentagon Looks to Militarize the Cloud). The Army is running a contest for mobile applications and talking about issuing smartphones to every soldier (A Smart Phone for Every Soldier?). Solutions are being displayed for sticking 3G cellular pods on a variety of vehicles, including UAVs (Forward Airborne Secure Transmissions and Communications).
So the forces that spawned network-centric warfare are still active, but as I concluded in the above-referenced blog post, so are the problems that have frustrated its implementation. Here’s a partial list of obstacles
- Lack of interoperability
- Development and acquisition pipeline logjam
According to at least one analysis, the current cost-climate climate means “… that the personnel and procurement budgets will be reduced to pay for O&M costs…” (Defense Industry Daily). As the demand for novel technology grows, acquisition budgets shrink. Defense wants the latest and greatest solutions, they want them now, and they want them to have a TRL level of 9 before they even see them. Government paying for research, testing, validation and verification? That’s so 20th century.
Using mature systems to develop advanced, useful solutions for today’s challenges is not impossible. Working with strategic partners, AMREL has developed System One, a Last Tactical Mile solution, a system composed of entirely battle-proven technology.
“The Last Tactical Mile” is a classic problem of network-centric warfare. Front-line troops are demanding real-time information. The days are over when data for C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance) only went to the “back-end” (headquarters located away from the front). However, getting this information into hands of the warfighter is a tremendous problem.
To appreciate the complexities of “The Last Tactical Mile,” imagine a team of Marines attacking a high value target in littoral waters. They might be deployed on an amphibious assault vehicle (whatever replaces the now-canceled Expeditionary Fighting Vehicle). In theory, this scenario could require connectivity among a UAV, external ship sensors, satellite networks, the amphibious assault vehicle, mother ship personnel, and the strike team deployed. Space is limited aboard the ships and all equipment must be ruggedized in order to withstand the harsh maritime and combat environments.
System One leverages AMREL’s broad range of from-factors for mature computing platforms, which are more than rugged enough to withstand the brutal vibrations of the high-speed landing craft, the corrosive conditions of the sea, as well as the violent realities of warfighting. AMREL’s durable, battle-tested PDAs are ideal for the Marine strike team. AMREL’s portable, rugged tablets could maintain communication with the amphibious assault vehicle’s coxswain as well as the mother ship’s onboard crew. Our fully functional 19/2® servers are1/4 the size of normal rack-mounted units, so they’re perfect for the cramped quarters of the assault vehicle. Designed to be flexible and to maximize connectivity, AMREL’s computers would have no problem tying the whole thing together with a MESH network.
System One has already successfully demonstrated the connectivity and reliability required for such a scenario. It can be installed on any vehicle, land or sea. It would function perfectly in the high-speed Stiletto boat and is small enough to fit in even the most crowded MRAP vehicle. In fact, it’s so compact, it is even man-portable.
An example of an advanced solution using mature, field-tested components, System One demonstrates that with careful strategic teaming and a bit of imagination, diminished government resources for research and testing can be leveraged into an opportunity.

Some computer manufacturers are eliminating IEEE 802.11b protocols, claiming that it will improve 802.11g. Since 802.11n is the fastest WLAN standard, why have any legacy Wi-Fi at all?
You need a, b, and g, because not all hot spots are running n. For example, if you’re operating an MQ-1 Predator by a wireless control system, while sipping a Frappuccino at Starbuck’s (you have your fantasies; I have mine), your computer better accommodate legacy Wi-Fi networks. If you know that your computer will be solely dedicated to a network that only supports 802.11n, then you don’t need connectivity for the older standards.
By the way, when you use your computer to conduct major combat operations from the local coffee house, be careful where you sit; data throughput dramatically decreases the further away you sit from an access point.
At AMREL, we see a lot of other people’s mistakes. Clients frequently come in with tales of woe, asking us to clean up messes made by them or their previous customization company. Some errors are specific to the customization process; others are true for rugged computers in general.
Of course, we’re happy for the business, but we think a little bit of knowledge can save everyone a lot of headaches. So, before you begin your journey through customization, take this short test to see if you’re ready.
Part One: True or False
Please indicate which of the following statements are true.
1) Mean Time Between Failures (MTBF) is a valid way of comparing quality of parts from different companies.
2) Customizations must be done by third parties.
3) The manufacturer’s warranty never includes customization.
4) Low-volume customizations are too expensive to be practical.
5) The warranty and purchase price reflect the true cost of the computer.
6) A signed obsolescence agreement with your vendor ends your worries about End of Life issues.
7) No such thing as “Customized COTS.”
Part Two: Name three wrong things the narrator did in the following story
“I needed a customized application for rugged computers. It was quite tricky. My team sat down, created a solution, and wrote the specs for it. We weren’t sure which rugged computer company to use, so we picked a large one, assuming they had the best capabilities. They explained to us that our specs weren’t practical. For one thing, the solid state hard drive required by our specs was much more expensive than we expected. We had to eliminate some of our wireless capabilities and other features in order to meet our pricepoint.”
Part Three: In one word, what is the most important thing to look for in a supplier of customized rugged computers?
