Advanced Thermal Management Solutions: Pumped Two Phase Cooling

To efficiently cool high-power electronics, lasers and other devices, advanced thermal management solutions are being developed including the use of pumped two-phase cooling. Traditional air and pumped single-phase cooling systems are large and heavy and in many cases, they cannot dissipate the necessary heat loads while maintaining the device below its maximum operating temperature. While Pumped Two Phase Cooling solutions offer a potentially lighter and more compact solution, they have not been broadly adopted by industry due to their increased complexity. Recent technical advancements have addressed many of these issues and the technology is poised for broader adoptions across many industries. Pumped two-phase cooling systems can now be tailored to meet increasing cooling requirements for a broad range of applications including high power electronics, laser diodes, and IGBTs. This presentation will provide design engineers with a better understanding of the fundamentals of pumped two-phase cooling technologies, including challenges, new solutions and opportunities for implementation.

Promote Interfacial Adhesion and Solve Delamination - An Engineer's Guide

Bonding high performance materials presents engineers with unique challenges to ensure immediate and long term interfacial adhesion success. Economic, environmental and productivity goals raise the stakes on the importance of finding the best solution when working with metals, polymers, adhesives, paints, coatings and other materials. In addition, more manufacturing materials are coming from the polymer composite world, which then must be adhered to metals and other substrates.

Real-Time Fiber Optic Strain and Shape Sensing (FOSS) Technology

Researchers at NASA’s Dryden Flight Research Center have patented a lightweight, fiber optics interrogation algorithm that can be used for real-time wing shape sensing, temperature, and strain measurements. The virtually weightless fiber Bragg grating sensors, along with NASA’s efficient algorithms, provide strain data that enable precise calculations of shape, stress, stiffness (bending and torsion), temperature, pressure, strength, and operational loads in real time. Unlike conventional strain gauges which are heavy, bulky, and spaced at distant intervals, NASA’s fiber optic sensors are small, non-intrusive, easy to install, and provide high-resolution (0.5-inch) strain measurements that are much more precise than ever before. This critical, real-time monitoring capability detects changes during operation without affecting the intrinsic properties of the structure and without the need for structural modifications.

Designing Graphics for Safety Critical Systems Using OpenGL SC

Some implementations for graphics in embedded systems don’t fly in safety-critical uses. For an application to be DO-178B/C certified, all its components must be certifiable. Requirements such as determinism, SWaP, radiation hardening, and others make the situation even more challenging for designers, limiting possibilities.
