AC/DC Switching Power Supply (ESC Booth #1028 )

Kontron (Poway, CA) introduces the CP3210 rugged conduction-cooled 3U CompactPCI® CPU board. The CPU board offers a clock rate of 733 MHz and DDR SDRAM of 226 MHz. The CP3210 incorporates a thermal sensor for health monitoring and thermal management. The 3U CompactPCI® CPU board is designed to meet the harshest and most demanding requirements through its very low-power dissipation, real-time and certifiable software support, and conduction- cooled design.

The Kontron CP3210 CompactPCI® CPU board offers a range of standard functions and expansion options including the new PowerPC G3 750FX RISC processor clocked at 733 MHz, onboard user memory of 512 MB DDR SDRAM with ECC clocked at 266 MHz, 128 MB of System Flash memory, 256 MB of User Flash memory, and 128 KB of nvSRAM with realclock. It also offers two onboard serial lines, two Ethernet channels (one Gigabit and one 10/100), and one 33/66 MHz PMC expansion slot (PCI Mezzanine Card). An additional PMC can be implemented via the rugged PMC carrier CPMC1. The CP3210 has reliable operation in temperatures ranging from -40°C to +85°C according to VITA 47 recommendations.

Increasing System Flexibility Using FPGAs

The proliferation of FPGAs into the embedded computing industry has opened up many new pathways for designers to design cost-effective systems that will withstand technology upgrades, changes in application requirements, and requests for low volumes for system components. Because it allows a user to update functionality after the device has left the manufacturer, FPGA technology gives embedded designers the flexibility to configure both customized and standard products. They can rethink the way systems are constructed and build ones that significantly advance existing technologies and blaze new paths for cutting-edge embedded systems.

StackableUSB™ Adapting PC Technology to the Embedded Market

Embedded systems and desktop PC's have had a love hate relationship over the years. The PC has been the source of significant technological advances that have enabled embedded systems to evolve to their current levels of sophistication, using the faster processors and highly-integrated functionality of the CPU cores available today. Additionally, the PC world has also spun off I/O buses, both serial and parallel, that have enabled embedded systems designers to expand and configure their system I/O. On the other hand, the embedded industry has often been wary to adopt PC technology due to the short life cycle some PC technologies experience.

Using Virtualization to Secure Mobile Device Designs

Mobile devices are increasingly coming under attack from malicious applications. As more complex operating systems (OS), such as Symbian, Windows Mobile, and Linux are used in handsets, providing security updates and identifying new vulnerabilities has become more complicated. Addition ally, frequent patching and rewriting of code to keep one step ahead of hackers undermines the utility and longevity of legacy software. What developers really need is an environment that is inherently safe from attack and provides the appropriate level of security for all code running in the target device. Secure, segregated areas for critical code must be combined with secure communications in order to provide protection for mobile devices.

Real-Time Data Distribution for Industrial Automation Systems

The quest to bring lockstep efficiency to labor intensive factory production at first relied on mechanical ingenuity. Over time, as reliable and cost-effective microprocessor technology became available, assembly lines were retooled to use the new electronics to achieve greater automation and productivity. Today, pervasive network technology, including the Internet, is bringing about another evolutionary change in industrial automation. No longer is it sufficient for individual machines to perform their specific tasks independently. Instead, individual parts of a larger process must be aware of each other; they must exchange data in realtime, and adapt to changes in the process or environment. Additionally, it is increasingly necessary to exchange data outside of the traditional industrial network and beyond the factory floor, and to include enterprise LANs and the Internet. Up-tothe- minute information on manufacturing processes needs to be available to analysts, inventory managers, and others within the office environment.

Macromolecular Carriers for Nanomedicine and Nano Devices

Tailoring the surface properties of biodegradable nanospheres and microspheres for in-vivo blood-contacting applications includes defining relationships among chemical composition, processing parameters, nanosphere sizes and size distributions, and surface structure. Developments include: 1) a facile method for achieving magnetite-polylactide nanospheres that can be dispersed in aqueous media; 2) methods for functionalizing the termini of the hydrophilic brushes on the nanospheres in order to conjugate targeting moieties; 3) development of a nanosphere processing approach that yields nanospheres in the desired size range with a narrow distribution of sizes; and 4) maintainence of all of these characteristics with up to approximately 60 weight percent of magnetite incorporated into the nanospheres.

Genetic Studies of Responses of Bones to Mechanical Stresses

Progress has been reported in a continuing program of molecular genetic studies of the responses of bones to mechanical stresses. Prior studies in mice and humans had provided evidence that mechanical loading stimulates bone formation and that immobilization or loss of mechanical stimulation leads to decreasing bone formation and increasing bone loss. Other prior studies in humans and mice had demonstrated that bone anabolic response differs widely among individuals subjected to the same degree of mechanical loading. The initiation of the present studies was motivated by the conjecture that variations in bone anabolic response among individuals are attributable to differences in the transcription levels of genes; that is, they are genetically controlled.

Characterization of a MEMS Directional Sound Sensor

There is a wide range of potential military applications in which ambiguity in bearing occurs with respect to sound. For example, autonomous unmanned aerial vehicles (UAVs) could employ a sensor to determine the bearing of an explosion and conduct battle damage assessment (BDA) on it. With existing sensors this is difficult to do because the explosion is too short in duration to use the Doppler effect to determine the bearing. Also, an autonomous underwater vehicle (AUV) acting as a quiet platform to tow a short, omni-directional hydrophone array must contend with bearing ambiguity.

Two-Camera Imaging System for Kinematic Measurements

A high-speed imaging system has been devised as a noninvasive means of collecting data on the kinematics of working models of developmental underwater or aerial vehicles that would utilize flapping fins or flapping wings for propulsion. The system includes two high-speed digital electronic cameras aimed along orthogonal axes that acquire snapshots of a model simultaneously in rapid succession. The data from successive images are postprocessed to obtain three-dimensional coordinates of points of interest on the model as functions of time. In the case of a flapping appendage, the points of interest are tips on the appendage, and the temporal evolution of the tip coordinates through multiple flapping cycles is utilized, in conjunction with computational fluid dynamics and other analytical tools, in an iterative process of testing and design directed toward improving the swimming or flying performance of the model. The system can, of course, be used as a noninvasive means of kinematic testing of models other than those of vehicles utilizing flapping appendages.

Synthesizing Pseudo-Finer-Resolution MODIS Data Products

A document discusses a methodology for synthesizing finerresolution data products from outputs of the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments aboard NASA's Terra and Aqua satellites. Typical MODIS ocean color data have 1-km resolution, but those in five wavelength bands have 500-m resolution and those in two wavelength bands have 250-m resolution. Finer-resolution bio-optical-property data products improve our capability for monitoring coastal ocean and estuarine processes.
