12V Front-End Distributed Power Supply

Emerson Network Power (Carlsbad, CA) has introduced the DS2900, a high-wattage 12V front-end distributed power supply. The Emerson DS2900 is rated for up to 2900W of adjustable output power at 240A. In addition to 12 VDC output, it offers 3.3 VDC auxiliary output for powering standby circuitry, and an optional alternative 5.5 VDC auxiliary output. The compact 2U × 3U form factor offers system-level power density of more than 24W per cubic inch. It offers typical operating efficiency of approximately 91 percent at 50 percent load. The power supply’s shorter form factor also allows mid-plane rack configurations, while same-side AC inputs and DC outputs allow hot-plug rack configuration.

UPS With Long-Life Batteries

Falcon Electric, Inc. (Irwindale, CA) has introduced a long-life battery in its SSG Series™ Industrial-Grade Uninterruptible Power Systems (UPS) Plus product line. The units are available in models from 1.5 to 3kVA and in both 120 VAC and 230 VAC versions, and are capable of withstanding elevated temperatures of up to 55°C for prolonged periods of time. The long-life battery is particularly suited to environments with temperatures that exceed 40°C, such as a factory floor, a desert setting, or any computer rack. In such temperatures, the batteries are rated to last at least twice as long as a standard five-year/40°C rated battery. Specifically, the long-life battery has an expected life of seven years at 40°C and four years at 50°C, as compared to a standard battery, which is rated to last less than two years at 40°C and less than a year at 50°C.

Using Parallel Processing on GPUs to Accelerate Finite-Difference Time-Domain Algorithms for Electromagnetic and Seismic Applications

Many scientific, technical and engineering applications in finance, medical imaging, modeling, simulation, and image processing can benefit greatly from the floating point acceleration offered by modern general purpose graphics processing units (GPGPU). Today’s graphics processors have evolved into sophisticated, massively-parallel, highly-programmable compute engines ideally suited for algorithms with a high degree of data parallelism. Combined with modern parallel programming languages and application interfaces such as industry standard OpenCL™, GPGPU offers a new paradigm for high-performance computing (HPC).

Using Multiprocessing in Industrial Automation Systems

Automated industrial control systems are an integral part of today’s manufacturing facilities. As these systems’ capabilities advance, the engineer shifts from someone who oversees processes to one who manages the data produced and functions performed by these systems to ensure product quality. Manufacturing systems need to be reliable, since downtime is an expensive alternative. Automation has reduced the number of people staffed at each facility so, if a system goes down, it’s probably not feasible for people to actually step in and move production along. If a system stops, so does production.

Using FPGAs for Automated Design Validation

In the design process, after the first prototype returns from fabrication, engineers often use traditional test equipment to make low-level measurements such as digital rise times, voltage thresholds, and leakage currents, and analog harmonic and spurious distortion, noise, and more. Once these parameters are verified to be within specification, higher-level attributes such as protocol compliance on digital devices and modulation parameters on communications devices are then checked. This gives the engineer a good understanding of how the device behaves, and whether or not that behavior allows the device to properly interact with the world around it. However, how can you guarantee that the device will continue to operate over time, with the myriad of permutations of device state, data content, and in the presence of non-ideal, real-world conditions? Who has the time to run all those tests?

Implementing Rack-Level I/O Consolidation

The desire to consolidate datacenter I/O has existed for several decades. It has been driven by I/O hardware providers who didn’t want to develop multiple versions of the same I/O card for different computer busses, and by end-users who did not want to stock multiple cards, as well as manage different fabrics with different tools. The problems that I/O consolidation needs to solve are:
