The GigE Vision® Interface Standard: Transforming Medical Imaging

Live, high-resolution imaging is increasingly being leveraged to enhance operating procedures. It can improve the precision of physicians and their instruments, and minimize the invasiveness of many procedures. Increasingly, one small component in a vision system — the interfacing technology — is providing answers to the most common of these challenges.

New Standards Allow More CPU Options in Embedded Computing

Embedded system designers often find themselves trapped by CPU design choices they made years earlier, since switching costs can be astronomical. Hardware development often involves processor-specific interface chips and board design. Software switching costs can be even more onerous, since CPU architectures drive the purchase of development tools and the requirement for customized software. However, a couple of industry trends have opened up the CPU platform, and system designers are gaining the ability to mix and match CPU suppliers or even change CPU instruction sets to optimize products across a wider range of applications.

Designing CompactPCI Systems with Serial Interfaces

With more than a year under its belt since it was officially ratified by PICMG in March of 2011, CompactPCI Serial (PICMG CPCI-S.0) has proven to be a good example of how an industry standard can be upgraded to meet the needs of evolving computing parameters while protecting the historical investments tied to the original architecture. The fact that it has found a new home in a wider variety of application environments is just one more benefit that this new computing standard offers.

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.

Optimizing Finite Element Material Models in a Crash Test Dummy

Finite element representations of crash test dummies are widely used in the simulation of vehicle safety systems. The biofidelity of such models is strongly dependent on the accurate representation of the nonlinear behavior of the constituent rubber, plastic, and foam materials. Advanced material models are often needed to capture the dynamic response of the various parts of the dummy. The process of calibrating a finite element material model is resource-intensive, as it involves optimizing model parameters to achieve good correlation with test data under different loading conditions and rates.

Reducing Machine Controller Design and Deployment

Machine design and deployment requires integration of various technologies such as controls, mechanics, vision, lasers, data acquisition, and software, to mention only a few. These mechatronic solutions usually target a specific purpose such as part manufacturing, marking, packaging, etc. Often the controller is a key focus in the design because it must connect and coordinate all of the processes on the machine. Using separate programmable logic controllers (PLCs) and motion controllers necessitates integration, which is costly and time-consuming. Using a single controller for the machine eliminates the need for integration and shortens design and deployment time and cost.
