Cell Technology Tackles 3D Medical Imaging Reconstruction Challenges

Medical imaging is an information processing technique that takes data samples from medical devices such as magnetic resonance imaging (MRI) or computer tomography (CT) scanners and translates them into 2D, 3D or even 4D images. Advances in sensor technology allow for the generation of an increasing number of images per procedure and per patient, posing a tremendous challenge for the efficient, in-time processing and visualization of the resulting images. In addition, sensor systems are now capable of acquiring thousands of projections per second, literally flooding the image reconstruction subsystem with several hundreds of Mbytes of data per second.

User Programmable FPGAs Power CompactRIO Embedded Systems

With a laundry list of design constraints, including a combination of real-time requirements, reliability/durability requests, and functionality and performance needs, it’s not surprising that engineers may find successfully building a competitive embedded solution difficult. To simplify the process, National Instruments developed a rugged, new high-performance embedded system, called CompactRIO, that combines the processing power and flexibility of a field-programmable gate array (FPGA) with the reliability of a real-time processor.

Using RapidIO® Technology as a System-Level Fabric

Both Serial RapidIO and Ethernet are being used as a backplane interconnect technology in a wide range of embedded applications. Many suppliers support both standards and let designers choose to work with whichever interconnect they feel is best. This neutral position provides interesting insights into both of these technologies. From a high-level point of view, it seems as if these two technologies are in stiff competition with each other. While Ethernet is certainly the incumbent technology, Serial RapidIO has had a huge uptake in adoption over the past year, with more silicon vendors supporting the standard than was originally anticipated.

Ruggedized Hard Disk Drives Keep Data Safe In Harsh Environments

Conventional hard disk drives (HDDs) are designed to reliably operate in the hospitable physical surroundings of interior deployments, which are typically characterized by mild temperatures, stable humidity and modest levels of vibration. By contrast, outdoor and mobile storage environments can entail anything from sweltering heat or sub-zero frost to oppressive dampness and pounding vibration. And all may be encountered miles above sea level. So it’s no surprise that bringing the benefits of HDD-based storage to outdoor and mobile settings such as automotive, industrial PC, field computing, and military applications poses a formidable challenge to engineers.

Cyber-Training Today’s Fighting Forces

Dramatic changes are taking place in the way U.S. service men and women prepare for their assignments. Since 9/11, the U.S. Department of Defense (DoD) is moving from a training cycle in which pre-deployment training events for units and staffs were predictable and occurred every 18-24 months, to one in which deployments are occurring every 10-to-12 months. The Department’s leadership views virtual simulation, where soldiers can experience a wider variety of realistic training scenarios more frequently, as one way to supplement live training to prepare its forces to go into harm's way

Embedded Development and the .NET Micro Framework

The scenario:

You’ve been assigned the task of designing and producing an embedded device. You’ve been given time, cost and size constraints that impact your design. An initial analysis of the requirements leads you to the conclusion that a 32-bit processor with a relatively small amount of RAM and Flash are required. A bit of research shows that an ARM processor with 2MB of external Flash and 2MB of external RAM will meet your cost and size constraints.

Embedded Security: Down to the Silicon

Embedded applications are increasingly going online. With the introduction of new embedded technologies that utilize a wide variety of communications options from Ethernet to Wi-Fi and ZigBee, there is a pressing need to secure these applications against the same problems that are inherent in any networked application.
