Available in PDF, EPUB and Kindle. Book excerpt: The interest on microfluidic systems based on electrowetting-on-dielectric (EWOD) and the miniaturization of such integrated devices, has increased significantly mainly due to the advent of mass market applications such as lab-on-chip, liquid lenses and reflective displays. The main objective of this work focuses on the scientific and technological challenges that the fabrication and optimization of liquid lens faces. Those are mainly related to the materials used and their associated fabrication techniques, in order to have stable devices with high performance for long term functionality. The work reported here contributes the research to reduce the actuation voltage and to increase stability and reliability of electrowetting devices such as liquid lenses at laboratory scale. We address various aspects related to liquid lenses: (a), improvement of the hydrophobic layer deposition process leading contact angle recovery enhancement, (b) investigation of the dielectric materials and deposition techniques to reduce the required applied voltage (c) specific design of electrodes for 2D movement of the liquid lens, and (d) investigation of nonaqueous liquids to improve the dynamic behavior and long term cycling functionality. (e) An attempt is made to develop behavioral models that can explain EWOD phenomena with an electronic circuit software.

Many new developments are comprehensively reviewed and explained, including aberration correction, acoustic measurements, acoustic radiation force imaging, alternate imaging architectures, bioeffects: diagnostic to therapeutic, Fourier transform imaging, multimode imaging, plane wave compounding, research platforms, synthetic aperture, vector Doppler, transient shear wave elastography, ultrafast imaging and Doppler, functional ultrasound and viscoelastic models
Download or read book Considerations in Contact Lens Use Under Adverse Conditions written by National Research Council and published by National Academies Press. This book was released on 1991-02-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes current understanding of the scientific, clinical, and technical issues surrounding the use of contact lenses. It discusses the special occupational conditions experienced by military personnel, particularly in extreme environments, that give rise to the question of whether or not to use contact lenses. Experts in optometry, ophthalmology, visual psychophysics, and engineering describe recent developments in design and use; and representatives of the military services provide examples of actual situations in aerospace settings. Considerations in Contact Lens Use Under Adverse Conditions will be of particular interest to those involved in the design of contact lenses and those responsible for occupational safety and health matters in the private sector.

Download or read book The Elliptical Cylindrical Liquid Lens written by C. Yeh and published by . This book was released on 1971 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of the focusing of pressure wave by a thick elliptical cylinder liquid lens has been treated in a rigorous manner. The size of the lens is of the order of or slightly greater than the wavelength of the incoming acoustic signal. Detailed computation has been carried out for a representative case in which a liquid lens with index of refraction of 1.8 and density of 1900 kg/cubic meter is assumed to be immersed in seawater. It is shown that a slight deformation of the boundary surface of a circular liquid lens results in significant changes in the location of the focalregion and that elliptical lens may provide stronger focusing than an equivalent circular lens. This research also points out the necessity pursuing an investigation on thin lenses where the focal regions are located outside the lenses. (Author).
