Shape Sensing Using Multi-core Optical Fibers with Distributed Fiber Bragg Gratings

Fiber optic sensors are being used for sensing everything from chemicals, to pressure, to structural loads, and temperature. Recently, multi-core optical fiber has enabled a new type of fiber optic measurement known as fiber optic shape sensing. While bonded fiber optic strain gages can be used to track shape changes of fairly rigid structures, their use in highly flexible structures such as inflatable vehicles or morphing flaps is limited due to the impracticality of bonding to such mediums. Multi-core fibers can sense structural shape changes and do not require bonding. A multi-core fiber optic cable embedded with distributed low-reflectivity Fiber Bragg Gratings can be interrogated using an Optical Frequency Domain Reflectometry system in order to measure local bending along the entire length of the fiber, which enables a position measurement of the multi-core fiber in three dimensions. Such fibers are being investigated for uses beyond aerospace, including undersea towed instrument position tracking, tether monitoring in tethered satellites, underground drill position tracking, and surgical catheter path monitoring. In this Webinar, the process of transitioning distributed strain measurements of multi-core fiber into a three-dimensional shape determination of the fiber is explained and the methods for including twisting and stretching measurements of the multi-core fiber into the solutions will be detailed. In addition to showing actual results, simulation methods relevant to the technique will be covered.

Vincent Systems Prosthetics Give Patients A New Feel For Life

The human hand is a biomechanical marvel and therefore hard to replace. Being ready to take up this challenge the Vincent Systems GmbH builds ultra-sophisticated prosthetic hands and partial hand systems since the founding in 2009. Ever since the Company attempts to mimic the range of the human hands natural capabilities by combining mechanical performance with an anatomically correct sized soft-shell design and an intuitive usage. This Webinar gives the audience a brief introduction to the daily work at the Vincent Systems GmbH and on how their products affect the life of prosthesis wearers. Precision, functionality and control have to go hand in hand with aesthetic design and natural feel. Vincent Systems masters all these challenges within PTC’s Creo 3D CAD system and the computing power of the HP Z420 workstation. You will get an overview about how these systems work and on how they are designed and build.

Advances in Metal Additive Manufacturing -- the Development and Applications of Electron Beam Freeform Fabrication (EBF3)

Metal additive manufacturing, also called “3D printing,” has blossomed over the past decade, growing from a novelty research area to commercial systems used in a variety of small-scale production applications. Electron beam freeform fabrication (EBF3) is an additive manufacturing process that builds three-dimensional metal parts layer-by-layer using wire feedstock and an electron beam heat source. Researchers at NASA’s Langley Research Center initiated development of EBF3 to address challenges in applying metal additive manufacturing to large-scale structural aircraft components, launch vehicles, and in-space manufacturing for building tools, spares and replacement parts for use in space. This webcast will discuss the maturation of the EBF3 technology from inception to commercialization and will describe some of NASA’s current and emerging applications of this additive manufacturing technology.

P2P Pumped Two Phase Cooling For High Heat Flux Applications

Thermal management solutions for powered applications are becoming more demanding. Traditional air-cooling and pumped single phase liquid cooling systems are becoming too large and heavy to address high heat load applications. Pumped Two Phase (P2P) Cooling solutions are now being more routinely applied for cooling high heat load, particularly when a high degree of isothermality is required. P2P cooling can be applied to all sectors from laser diodes to IGBTs to large scale system applications. This presentation will provide design engineers with a better understanding of the fundamentals of P2P cooling technologies, including new solutions and opportunities for implementation.
