Cryogenic Nano - Actuator for JWST
An extremely precise positioning mechanism has been developed for use in space for optical positioning of large mirrors. The design incorporates traditional mechanical components such as gears, bearings and flexures in a unique configuration covered by two patents. This linear actuator is capable of 10 nanometer position resolution over a range of 20 mm and can operate under cryogenic condition...
متن کاملFabrication of PGS/CaTiO3 Nano-Composite for Biomedical Application
Biodegradable elastomeric materials are gaining extensive attention in the field of soft tissue engineering. Poly (glycerol sebacate) (PGS) is a novel biocompatible elastomer in this scope. However this polymer has poor mechanical properties especially when the molar ratio of glycerol is higher than sebacic acid. Calcium Titanate (CaTiO3) is a biocompatible ceramic with some degr...
متن کاملNano-optomechanical actuator and pull-back instability.
This paper studies the nonlinear behavior of a nano-optomechanical actuator, consisting of a free-standing arc in a ring resonator that is coupled to a bus waveguide through evanescent waves. The arc deflects when a control light of a fixed wavelength and optical power is pumped into the bus waveguide, while the amount of deflection is monitored by measuring the transmission spectrum of a broad...
متن کاملFigure mining for biomedical research
MOTIVATION Figures from biomedical articles contain valuable information difficult to reach without specialized tools. Currently, there is no search engine that can retrieve specific figure types. RESULTS This study describes a retrieval method that takes advantage of principles in image understanding, text mining and optical character recognition (OCR) to retrieve figure types defined concep...
متن کاملDesign and Development of a Two-axis Reluctance Based Actuator for Hexflex Nano-positioner Design and Development of Two-axis Reluctance Based Actuator for Hexflex Nano-positioner Acknowledgements
An endeavor was conducted to explore the design and development of a two-axis linear reluctance actuator for use as a part of a nano-positioner with the application of serving as a small scale kinematic coupling assembly station. This nano-positioner is designed to be able to accurately and repeatable provide precise motion control of small objects with a resolution on the nanometer scale. This...
