Open Standard Middleware Enables New HPEC Solutions

The military embedded computing landscape has been transformed from where it was 20 years ago — and that has been almost entirely enabled by the ability of prime contractors, systems integrators, and OEMs to leverage the products of COTS manufacturers who take leading edge commercial technologies and apply them successfully to the world of military computing. A look at the commercial landscape today reveals cell phones that are putting vast amounts of location- aware information — and the ability to process that information — directly into the hands of consumers. The Internet of Things has become a deployable reality, with data derived from millions of connected sensors.

Cooling Your Embedded System: What Can Your Open Standard Architecture Handle?

Embedded computing systems for Mil/Aero applications are often conduction-cooled in an ATR or nonstandard chassis. However, there are many designs that require 19" rackmount systems with forced-air cooling. As more processing performance is packed into tight spaces, enclosures that provide advanced cooling options are increasingly common.

Evaluating Key Certification Aspects of Multicore Platforms for Safety Critical Avionics Applications

High performance, low power consumption and small footprint requirements imposed by the embedded market on the processor industry is causing a definite move away from single-core processors to multicore processors. Multicore processors have been deemed as the future of Size, Weight, and Power (SWaP) constrained applications like military and avionics. They provide higher performance (MHz/W) at lower power. They also allow consolidation of multiple functions/ applications onto a single platform.

Advances in Lightweight Electronics Protection

Lightweighting continues to be a key topic for the aerospace, avionics and defense industries as new metals and composites are being integrated into end products and assemblies with the goal of decreasing overall system weight. As technologies continue to evolve, with components often decreasing in size and increasing in complexity, the materials used to manufacture and protect the latest components and systems are also improving. Whether used in commercial or military aircraft, rockets, satellites, terrestrial or water vessels, or the latest in unmanned air, land and sea vehicles; systems within these industries must meet similar requirements – assemblies, components and electronics must be both lightweight and designed to withstand harsh operating conditions.

Powering Outer Space: An In-Depth Look at Aerospace Battery Technology

With space’s extreme environments, there is never a one-size-fits-all battery. Nor is any space mission ever the same, so customized batteries for each operation are essential. Saft, has been powering outer space for more than 50 years. Saft’s first battery was launched into space in 1966 aboard the D1A “Diapason”, which was powered with nickel cadmium (Ni-Cd) technology. To date they are the only battery manufacturer to supply all battery technologies used in space: Nickel (Ni-Cd, Ni-H2), primary lithium (Li-SO2, Li-SOCl2 and Li-MnO2) and rechargeable lithium or lithium-ion (Li-ion).

Advanced Thermal Management Solutions

Now more than ever, devices with increasing power and smaller footprints are demanding a good stable cost effective thermal management solution. Fortunately many options are available today. However, for device packaging designers not familiar with these technologies, determining which thermal management technology is appropriate for their application can be a challenging task. To help sort out the many options, here is an overview of three very different thermal technologies: passive heat pipes, pumped two-phase cooling systems and temporary thermal storage/ phase change materials (PCM) heat sinks. In each case we’ll provide an overview of each of these technologies, explain how they function and provide some examples of when they should be considered.

Thermoelectric Cooling

There are many places one can go to get an outline on the pros and cons of different methods for enclosure cooling. Although we will briefly touch on them here, this is really an in-depth article on how to choose a Peltier (thermoelectric) air conditioner, once you have committed to the technology.

Thermal Ground Planes Optimizing Heat Transfer in Aerospace and Defense Applications

Wide band gap (WBG) semiconductors are semiconductor materials that allow higher voltages, higher frequencies and operation at higher temperatures over conventional electronic materials, thereby allowing higher performance electronics to be constructed. The Defense Advanced Research Projects Agency (DARPA) understood the advantages of using WBG in aerospace and defense applications but also understood that thermal management was going to be a significant technical challenge to achieving the full potential of WBG technology. Accordingly, to overcome these and other challenges, DARPA sponsored the development of a new form of heat pipe, known as a Thermal Ground Plane (TGP), to effectively cool WBG devices.

Thermal Management of Laser Diodes

High-power laser diodes can generate a great deal of heat. Even for laser diodes operating with 70% or higher efficiency, a large amount of applied energy is converted to heat. Since the performance and optical efficiency of a laser diode is dependent upon operating temperature, maintaining a stable temperature close to room temperature (about +25°C) is instrumental in achieving high reliability.

Cloud Security & Compliance

What Every Defense Organization Needs to Know

Not too many years ago, network security was a relatively low level priority in most organizations. That has changed today due to such high level failures as the recent breaches at Sony and Target. Closer to home, the University of Maryland is now incurring large expenses for all students due to the recent leak of personally identifiable student information.
