MASKING AND SHADOW HEARING IN BONE CONDUCTION

Archives of Otolaryngology - Head and Neck Surgery, 1950
IN THE performance of a hearing test the object of masking is to keep one ear occupied while the other ear is being tested. A complex noise consisting of the essential frequencies gives a satisfactory masking effect. The specific areas on the basilar membrane will resonate to the complex masking sound and will become refractory to stimulation from ...

Automated shadow mask inspection using DSP

Proceedings IROS '91:IEEE/RSJ International Workshop on Intelligent Robots and Systems '91, 2002
Presents a new shadow mask inspection method which can detect the very small hole defects reliably and rapidly; the shadow mask line image data is periodical. The inspection method mainly depends on the fact that a small defect can be significantly emphasized in terms of the comparison between the image pixels departed by the period.

AN APPROACH OF SHADOW MASK FOR DEEP-HOLES PATTERNING

International Journal of Computational Engineering Science, 2003
This paper presents a method to pattern metal in deep holes. We do this by etching holes through a separate wafer to form a shadow mask and then depositing metal by electron-beam evaporation or sputtering through the holes on this shadow mask on to the device wafer.

Efficient visibility masking for crowd rendering with shadows

SIGGRAPH Asia 2012 Posters, 2012
Virtual real-time applications such as games and simulations frequently require rendering of large number of agents. Various GPU accelerated eye space culling and level of detail management techniques are being used to achieve efficient rendering of massive virtual crowds. However effective light space rendering is important for shadow mapping.

Printed shadow masks for organic transistors

Applied Physics Letters, 2007
We have manufactured organic field-effect transistors by using shadow masks that are patterned by a screen printing system. The 50-nm-thick pentacene layer is sublimed as a channel in the vacuum system through the shadow mask on the base film with a multilayer patterned by ink-jet.

Mask and shadow: for large orchestra

2014
Mask and Shadow pour orchestre explore le concept esthétique d'imperfection en composition musicale. Cette thèse se présente en deux parties: La partition complète et l'analyse. La méthode originale par laquelle ce concept est mis en marche dans cette composition musicale comporte deux éléments: D'abord le concept d'imperfection est subdivisé en ...

A shadow-mask evaporated pyroMEMS igniter

Journal of Micromechanics and Microengineering, 2011
A reliable pyroMEMS igniter was successfully demonstrated based on shadow-mask evaporation of metal directly onto solid propellant drops. In this way, intimate contact between the fuel and the igniter was guaranteed. No visible degradation of the fuel was observed after the evaporation. A preliminary process-parameter study was carried out.

Shadowing 3D mask effects in EUV

SPIE Proceedings, 2012
A new method to evaluate the shadowing effect of 3-dimensional mask has been developed and implemented for extreme UV technology. The method is composed of several key ingredients. The illuminator(source) is divided into very small domains to account for the partial coherence nature of the illumination employed by the microchip industry.

Production of shadow-mask-improved technology

Journal of Materials Processing Technology, 2002
Abstract A shadow-mask is a specific metal plate that is used in color TVs and computer monitors. Manufacturing is generally composed of coating, cleaning, exposure and etching processes. After a thin metal plate is made by rolling, a photosensitive liquid is coated on the metal plate in a coating process.
