Abstract: Un dispositivo protector que comprende un cerramiento que incluye una entrada de gas, una salida de gas y un indicador multicapa en capa fina, en donde: A) el cerramiento contiene medio sorbente que puede sorber un vapor de interés que fluye desde la entrada hacia la salida; B) el indicador multicapa en capa fina comprende: i) una capa porosa detectora cuyo espesor óptico cambia en la presencia del vapor, situada entre ii) una capa semirreflectante que se puede ver desde el exterior del cerramiento y iii) una capa reflectante permeable al vapor; y C) la capa reflectante está lo suficientemente cerca del medio de forma tal que en estado de equilibrio a la concentración de vapor aplicada entre al menos una parte del medio y el vapor, el vapor puede pasar del medio por la capa reflectante y hacia la capa de detección y cambiar el espesor óptico de la capa de detección lo suficiente para producir un cambio discernible visiblemente en el aspecto del indicador tal como se observa a través de la capa semireflectante.

Abstract: A sorbent media protective device includes an enclosure having a gas inlet, gas outlet and a thin-film multilayer indicator. The thin-film multilayer indicator is proximate sorbent media that can sorb a vapor of interest flowing from the gas inlet towards the gas outlet. The indicator includes a porous detection layer whose optical thickness changes in the presence of the vapor, located between a semireflective layer and a reflective layer permeable to the vapor. With equilibration at the applied vapor concentration between at least a portion of the media and the vapor, the vapor can pass through the reflective layer into the detection layer and change the detection layer optical thickness sufficiently to cause a visibly discernible change in the indicator appearance if viewed through the semireflective layer.

Abstract: C WURPorbnDCC\HFSW240623.I DOC-28A)3/2012 An optically-responsive multilayer reflective article is formed by applying a dilute solution or suspension of metallic nanoparticles to an optically-responsive detection layer. The 5 solution or suspension is allowed to dry to form a semicontinuous liquid or vapor permeable light-reflective layer that will permit a liquid or vapor analyte to pass through the light-reflective layer to cause an optically-responsive change in the detection layer in the presence of the analyte.

Abstract: The present invention relates to increasing the photosensitivity of optical fibers. One aspect of the present invention comprises a method for rapidly diffusing hydrogen or deuterium into an optical fiber from a gas mixture having a low total hydrogen content to generate changes in the refractive index of the optical fiber. The resulting photosensitive fiber may be used to create optical devices including Bragg gratings and Bragg grating-based devices.
