Using Laser Direct Structuring (LDS) to Create Robust Hardware Security Devices

Awide range of devices are designed to handle, convey and store sensitive information that requires varying degrees of security from protecting low level administrative to classified and top secret information. In addition, the information and data can reside in an equally wide range of locations and environments from protected and guarded facilities to unsecure desks and offices and over a wide range of environmental conditions including temperature, humidity, shock and vibration.

VPX-SC N-dimensional Supercomputing Architectures Come To The Critical Embedded Systems Market

From the first computers of the 1940s through the machines of the 1990s, all computer systems were CPUbound. In other words, the I/O interfaces could deliver more data than the CPU could process. In the 1990s Moore’s Law took over and clock speeds doubled every 18 months, along with the addition of multi-core processors. So, from 1990 through today, we have been I/O-bound, meaning CPUs can now process more data than the I/O links can deliver. Increases in CPU performance have been revolutionary while the increases in interconnect bandwidth have been incremental for many decades. However, bandwidth increases in RapidIO, InfiniBand, and Ethernet are breaking this bottleneck, giving us the ability to design incredibly powerful embedded supercomputing architectures for today’s dataintensive applications.

Uninterruptible Power Supply

Rugged Power Supply Protects Aircraft Carrier’s Voice-Data-Video Network Node

Earl Integrated Power & Controls, a division of Earl Industries (Portsmouth, VA), was enlisted by the U.S. Navy to create an innovative, vertically mounted voice-data-video (VDV) network node for the Ford Class Aircraft Carrier. One of the major challenges in this endeavor was that the rugged uninterruptible power supply (UPS) required to power the system would have to be equally innovative, owing to the node’s vertical orientation; the need for extended battery backup runtime; quick replacement of the unit’s power factor correction board; access to the Ethernet switch; and limited space availability.

Interoperable Communications Platform

NATO Special Forces Taps Mutualink for Global Cross Coalition Communications

NATO Special Operations Forces Headquarters (NSHQ) recently selected Mutualink as its official interoperable communications platform. Using Mutualink’s ruggedized Valence™ series platform, NATO SOF coalition partners will be equipped with advanced anywhere, anytime, interoperable communications and information sharing capability. This next generation capability securely links warfighters and command and control elements with each other as needed across different communications systems and allows them to share real time ISR, including files, maps, system views and full motion video (FMV) on the fly. For NATO SOF, quick reaction time and agile response capabilities are a must. Often first on the ground in challenging operational environments, harnessing collaborative multi-national information and intelligence sharing and seamless communications capability is critical.

Fastener Inserts

Fastener Inserts Designed for Lightweight Aerospace Materials Reduce Risks, Costs

Ongoing efforts to increase fuel efficiency, tactical mobility, and payload capacity in aerospace design have driven engineers to find numerous ways to reduce mass through the extensive use of lightweight materials such as composites, aluminum, and plastics. Use of these lightweight materials can create other issues, however, such as finding safe and reliable ways to fasten assemblies that provide complete assurance of joint integrity under the severe conditions of shock, vibration and thermal cycling common in aerospace applications.

Testing Ethernet Based Avionics in Aircraft

Since the 1970’s, military aircraft avionics systems have communicated via the MIL-STD-1553 bus. This has proven to be a very effective method, and is still in widespread use today. MIL-STD-1553 is a time division multiplexed command and response bus with a bus controller initiating all communications on the bus. The bus operates at 1 Mbps, and is dual redundant for reliable operation.

The Evolution of AdvancedTCA How Far Has It Come?

AdvancedTCA (ATCA) continues to evolve to meet not just the market demands for the telecom central office, but networking, data center, medical, and military communications applications. The two main goals that ATCA suppliers have been trying to solve often conflict with each other: offering more performance in less space, while meeting the specific market and compliance requirements for each industry.
