20090001284 | Biosensor with One-Dimensional Sub-Diffraction-Limited Apertures Composed of a Grid and a Polarizer - A method and sensor for the detection of luminescence radiation generated by at least one luminophore is disclosed. In the context of the present invention the biosensor comprises a grid ( | 01-01-2009 |
20110293712 | COAXIALLY ENCAPSULATED CELL SUSPENSIONS AND MICROTISSUES - The present invention provides for the coaxial encapsulation of a plurality of cells in a single elongated compartment. By this encapsulation, the cells are protected by at least one layer of separation material and kept in close contact, which leads to a better vitality of the encapsulated cells and consequently results in higher chances to form microtissue. Methods and devices for the production of such encapsulated cell compartments are disclosed as well as medical uses of such compartments in cell, tissue therapy and tissue engineering. | 12-01-2011 |
20120033173 | MULTIFUNCTIONAL OPTICAL SENSOR - The invention relates to a multifunctional optical sensor, having at least 2 areas which independently react to different input parameters, the sensor comprising a substrate and a polymeric layer comprising polymerized liquid crystal monomers having an ordered morphology, wherein the color, the reflectivity or the birefringence of the sensor changes due to a change of the morphology, wherein said change of the morphology is caused by physical contact with a chemical agent such as a gas or liquid a change of temperature, or passage of time. The invention also relates to a process for the preparation of the sensor and for the use of a film comprising a single substrate, a layer having a cholesteric liquid crystalline structure for application in labels for packaging of perishable goods, food, fine chemicals, bio-medical materials. | 02-09-2012 |

20130329447 | FLAT OPTICAL FIBER LIGHTING ASSEMBLY WITH INTEGRATED ELECTRICAL CIRCUITRY - Lighting assembly comprises an optical fiber light guide panel member having a light conducting core cladded on opposite sides by cladding made of optically transparent material having a lower index of refraction than the light conducting core to cause total internal reflection of conducted light within the light conducting core at the core-cladding interface. Disruptions at one or more areas of the cladding cause conducted light within the light conducting core to be emitted from one or more areas of the panel member. Electrical circuitry is bonded to one or both sides of the cladding. One or more LEDs embedded in the panel member are in electrical conduct with the electrical circuitry and optically coupled to the light conducting core. | 12-12-2013 |
20140022812 | DISPLAY FRONT LIGHTING DEVICE - A display front lighting device comprises an optically transmissive sheet member that provides reflective means to evenly distribute light for the illumination of the text and/or graphics of display modules while permitting the text and/or graphics to visibly pass through the sheet member for viewing. The transmissive sheet member has LEDs offset mounted at an angle relative to one side of the sheet member such that a portion of the light emitted by the LEDs is reflected by the one side onto the adjacent dis play. The LEDs are mounted on a flexible printed circuit board, or alternatively on the conductive traces bonded to the sheet member. | 01-23-2014 |
