Designing Solid State Drives Into ATCA-based Platforms

Due to the growth of video on demand (VoD), IPTV media content, and embedded database applications, AdvancedTCA (ATCA)-based storage capacity requirements continue to increase exponentially. In addition, storage requirements have become more complex and varied for ATCA designs that have expanded beyond the central office to include network data center and general data center applications that need to handle a wide variety of server platforms. The advancements and general availability of new storage solutions, particularly solid state drives (SSDs), enables ATCA platform developers to meet the design metrics of a broader range of markets where distributed data storage and management become increasingly required. The continual evolution of SSD storage technology, with its improved capacity, performance, and cost reductions, provides additional opportunities for integrating storage directly into the ATCA platform, allowing new designs to gain the benefit of high performance and availability provided by ATCA-based systems.

Achieving Embedded Software Safety with Agility

Safety-critical development standards, such as DO-1781, have been very successful in guiding the production of reliable software. These standards assist developers in applying good software practices during development, ensuring, as much as possible, the absence of errors. Compliance with these stringent standards involves a high cost because of their labor-intensiveness and high levels of know-how.

Cooling Lasers with Thin-Film Thermoelectric Coolers

Laser diodes for telecommunications have traditionally used thermoelectric coolers (TECs) for precision temperature control to improve diode output levels and maintain wavelength integrity. A major trend for photonics in telecommunications has been the move to more integrated packaging that is smaller and simpler in structure in order to lower costs. This, in turn, has opened the door for higher volume manufacturing. In the course of this transition, conventional TEC solutions have become increasingly difficult to implement as conventional bulk thermoelectric technology has not kept pace with the size and power density requirements for next generation devices.

Teleoperation of Unmanned Vehicles Using Immersive Telepresence

In order to extend the usefulness of small, unmanned ground vehicles (UGVs) to a wider range of missions, techniques are being developed to enable high-speed teleoperated control. Our goal is to quadruple the speed of teleoperated UGVs compared to currently deployed models. The key limitation is not mechanical, but in the capability of the operator to maintain situational awareness and control at higher speeds. To address these issues, we are developing technologies for immersive teleoperation and driver-assist behaviors.

Advances in Magnetic Bearings

In this age of environmental consciousness, OEMs around the world are competing to build better, safer, and greener machines. In striving toward such lofty goals, many industries are rediscovering a fundamental principle — magnetics. Magnetic bearings improve reliability, reduce friction, minimize vibration, and offer advanced health monitoring and diagnostics — all without the disadvantages of lubricants.

Hermetic Feedthroughs: A Critical Component in New Flywheel Energy Storage Solutions

The phrase “everything old is new again” certainly applies to today’s flywheel technology. Forget the mechanical bearing, standard atmosphere 5,000 RPM steel behemoths of the past, many of today’s flywheel designs feature compact carbon fiber composite rotors on magnetic bearings, turning in a vacuum at up to 60,000 RPM.
