Trimming Wiring Harnesses Becomes Design Focus

Wires and cables help design teams add electronic features and functions, but networks and wiring harnesses add a fair amount of weight while their connections can be the cause of failures. That’s prompting developers to examine ways to reduce the size and weight of wires and cables. Read more at http://articles.sae.org/13419.

Open Generic Avionics Architectures and Distributed Processing Using Ethernet and VPX

The backplane and hardware module standards help to increase part commonality and the reuse of components in different system architectures and applications, but this is only one part of the system design challenge. While the specified footprint, backplane format, and electrical signal characteristics help the design of modular hardware and open architectures, they still tell very little about how modular (and unambiguous) the interfacing among functions and their interactions are. This aspect is covered at the system integration (network) layer.

Small Form Factor Strategies for Military Embedded Systems

The proliferation of unmanned military vehicles tasked with critical communications and radar requirements drives the need for powerful data acquisition and signal processing products that must fit into increasingly tighter spaces. New industry standards meeting these needs offer smaller circuit boards and enclosures, optical gigabit serial links, and advanced thermal management strategies. With new resources found in the latest processors and FPGAs, system designers can now create powerful, compact systems surpassing performance levels achievable only a few years ago.

Electronics Take Charge

Electronic controls are slowly transforming aircraft engines of all types, bringing improved fuel consumption, improved efficiency, and more power. As the functionality of control units for jet engines increases, digital management is also adding more capabilities for helicopters and small piston engines.

iSLC Flash Technology

Robots have been employed by the military to assist in missions where it would be, and has been, too dangerous to have a human being take on the task. These robots can detect and disable bombs. Some can be thrown into rooms where they land on their “feet”, and scan the room for counter-insurgents. Others blow up mine fields, to ensure safe travel of ground vehicles and the personnel they carry.

From VME to VPX

Sequestration, defense reform and cost constraints are driving a new paradigm in the defense industry, where leveraging existing technologies is no longer optional, but required. This is especially true as we migrate from VME to VPX-based embedded computing.

CompactPCI Steps Into the Future

CompactPCI Serial has proven to be a beneficial technology upgrade for a number of embedded systems designers accustomed to working with the legacy CompactPCI platform. Not only does CompactPCI Serial bring modern serial interfaces and a ruggedized connector scheme into play, but it also provides significant cost advantages while adhering to many known design principles, lessening a developer’s need to learn a new and complex technology.

The Evolution of AdvancedTCA: From telecommunications to military, aerospace and security

The Advanced Telecom Computing Architecture (AdvancedTCA® or ATCA®) is a series of open standard computing platform specifications originally ratified in 2002 to meet the needs of carrier grade communications equipment, primarily for core network telecommunications applications. In the 11 years since ATCA products first appeared on the market, there have been numerous advances in the governing standard, the products available, and the products and applications that are driving its adoption and growth.

Designing Rugged, Standards-Based Embedded Solutions

It can be argued that small form factor design trends are paradoxical. As form factor size decreases, functionality requirements increase; as processing power requirements heighten, lower power consumption and thermal output is expected. Add to that the requirement for ruggedness to accommodate for the shock, vibration, humidity, and temperature extremes and variance inherent in mobile and outdoor applications, and designers are faced with a very complex soup.

Tips for Selecting or Designing a Membrane Switch

Membrane switches are known for standing up to tough environmental conditions. Flexible and durable, the membrane switch can be customized with embossing, backlighting, sealing, and electrostatic discharge (ESD) shielding. Membrane switches can be made with either tactile or non-tactile feedback and they can be integrated with LEDs and other components. To get the switch that works for your application, follow these simple guidelines.
