Filed: 2001-10-04
Abstract: Light from a light source (1) is fed into a resonator comprising an resonator fiber (3) and highly reflective couplers (4, 5). Light coupled out of the resonator fiber (3) is detected by a light sensor (7).      The resonator is built such that its losses depend on a physical parameter to be measured. The light fed to the light source is switched on and off in step-like manner and the corresponding build-up or decay of the light de-tector signal is used to determine the time constant of the resonator and therefrom the physical parameter. It is found that, even when light of a comparatively broad bandwidth is used, accurate measurements of the time con-stant are possible.

Filed: 2000-03-01
Abstract: La centrifugation est utilisée pour induire et/ou améliorer la liaison entre des cibles macromoléculaires et des ligands à petites molécules ou de grandes biomolécules pris séparément ou mélangés. Grâce à cette amélioration, le procédé permet de détecter les ligands qui se lient aux substances cibles et qui améliorent la conception de ces ligands. Le processus se fonde sur la force centrifuge pour établir un gradient de concentration différentiel et sélectif entre les cibles thérapeutiques macromoléculaires et les ligands souhaités. Une fois formés, on obtient des informations relatives aux événements de liaison autosélective dérivées de l'analyse du gradient différentiel des macromolécules et des ligands in situ ou du fractionnement du gradient en échantillons individuels en vue d'une analyse indépendante. Une grande variété de procédés ou leur combinaison peuvent servir pour rechercher des taux améliorés de ligands liés.

Title: Electrophoretic, high index, or phase transition control of total internal reflection in high efficiency variable reflectivity image displays
Inventor: KOTLICKI ANDRZEJ
IPC: G02F1/1677
Filed: 2000-05-26
Abstract: Charged particles (21) suspended in a medium (20) such as Fluorinert.TM. Electronic Liquid are used to electrophoretically control total internal reflection (TIR) at a retro-reflective surface formed on a high refractive index material. Prismatic structures (35, 32, 81) redirect ambient light from an overhead light source toward a display image and then from the image to the region in front of the image, yielding a high contrast reflective display. A transparent planar waveguide (36) front lights the display with sequential flashes of red, blue and green light to generate a full colour display. TIR can also be controlled at retro-reflective surfaces by means of a vapour-liquid phase transition, or by changing the absorption coefficient of a material using electrical, chemical and/or electrochemical methods.
