Publication number: 20140252342Abstract: Disclosed is an encapsulation barrier stack, capable of encapsulating a moisture and/or oxygen sensitive article and comprising a multilayer film, wherein the multilayer film comprises: one or more barrier layer(s) having low moisture and/or oxygen permeability, and one or more sealing layer(s) arranged to be in contact with a surface of the at least one barrier layer, thereby covering defects present in the barrier layer, wherein the one or more sealing layer(s) comprise(s) a plurality of encapsulated nano-particles, the nanoparticles being reactive in that they are capable of interacting with moisture and/or oxygen to retard the permeation of moisture and/or oxygen through the defects present in the barrier layer. The encapsulation of the particles can be obtained by polymerising a polymerisable compound (a monomeric or a polymeric compound with polymerisible groups or) cross-linking a cross-linkable compound on the surface of the reactive nanoparticles.Type: ApplicationFiled: October 24, 2012Publication date: September 11, 2014Applicant: AGENCY FOR SCIENCE, TECHNOLOGY AND RESEARCHInventors: Senthil Kumar Ramadas, Saravan Shanmugavel

Patent number: 8603772Abstract: This invention provides a novel methods and devices for measurement of particle concentration or changes in particle concentration over a wide linear range. The invention comprises one or more radiation sources and one or more detectors contained in a housing which is interfaced to a medium containing particulate matter. The one or more radiation sources are directed into the medium, scattered or transmitted by the particulate matter, and then some portion of the radiation is detected by the one or more detectors. Methods for confining the measurement to a specific volume within the medium are described. Algorithms are provided for combining the signals generated by multiple source-detector pairs in a manner that results in a wide linear range of response to changes in particle concentration. In one embodiment the sensor provides non-invasive measurements of biomass in a bioreactor. In another embodiment an immersible probe design is described, which may be suited for one-time use.Type: GrantFiled: July 28, 2008Date of Patent: December 10, 2013Assignee: Bug Lab LLCInventors: Martin P. Debreczeny, Jaime Romero, Ethan Petersen

Patent number: 8040609Abstract: A self-adjusting solar light transmission (daylighting) apparatus includes a sunlight concentrating member (e.g., a lens array) for concentrating direct sunlight in focal zone regions disposed inside a sheet containing an evenly-distributed stimuli-responsive material (SRM) that has a relatively high transparency state in the absence of concentrated sunlight, and changes to a relatively opaque (light scattering or absorbing) state in small portions located in the focal zone regions in response to concentrated direct sunlight. Thereby, 80% or more of direct sunlight is prevented from passing through the apparatus, but 80% or more of diffuse light is passed. The outer sheet surfaces are locally parallel (e.g., planar) such that sunlight scattered by the light-scattering SRM portions is transmitted by total internal reflection through the remaining transparent sheet material, and outcoupled to one or more optional solar energy absorbing structures (e.g.Type: GrantFiled: November 29, 2010Date of Patent: October 18, 2011Assignee: Palo Alto Research Center IncorporatedInventors: Philipp H.

Patent number: 7423259Abstract: A mass spectrometer comprises an ion detector, a first amplifier, a second amplifier, and a spectra combiner. The ion detector is configured to generate an analog signal indicative of ions detected by the ion detector. The first amplifier is configured to amplify the analog signal to provide a first amplified signal having a first gain relative to the analog signal. The second amplifier is configured to amplify the analog signal to provide a second amplified signal having a second gain relative to the analog signal, and the first gain is different than the second gain. The spectra combiner is configured to combine first summed digital samples of the first amplified signal with second summed digital samples of the second amplified signal.Type: GrantFiled: April 27, 2006Date of Patent: September 9, 2008Assignee: Agilent Technologies, Inc.Inventors: August Jon Hidalgo, John Christian Fjeldsted, William Daniel Frazer, Carl Alan Myerholtz

Patent number: 6094273Abstract: Devices that comprise novel, mesoscopically periodic materials that combine crystalline colloidal array (CCA) self-assembly with the temperature ined volume phase transitions of various materials, preferably poly(N-isopropylacrylamide) (PNIPAM) are disclosed. In one embodiment, a PNIPAM CCA is formed in an aqueous media and contained within cell means. In another embodiment, a CCA of charged particles is formed and polymerized in a PNIPAM hydrogel. Methods for making these devices are also disclosed. The devices of the present invention are useful in many applications including, for example, optical switches, optical limiters, optical filters, display devices and processing elements. The devices are further useful as membrane filters. All of these devices have the feature of being tunable in response to temperature. Devices that change diffracted wavelength in response to pressure are also disclosed.Type: GrantFiled: September 15, 1998Date of Patent: July 25, 2000Assignee: University of Pittsburgh of the Commonwealth System of Higher EducationInventors: Sanford A.
