Publication number: 20130141726Abstract: The invention relates to a sensing device (1) for detecting a substance (3) in a fluid (6), wherein the sensing device (1) comprises a sensing region (2) for being used for generating a sensing signal depending on the substance, a reference region (4) for being used for providing a reference signal, and a reference element (5) covering the reference region (4). The reference element (5) is adapted to shield the reference region (4) from the substance (3) and to allow the fluid (6) to penetrate the reference element (5). This reduces the influence of the reference signal by the substance (3) and, since the reference element (5) is adapted to allow the fluid (6) to penetrate the reference element (5), differences regarding properties of the fluid (6) at the sensing region (2) and of the reference element (5) at the reference region (4) can be reduced. This reduction leads to an improved reference signal, which can be used, for example, for correcting the sensing signal.Type: ApplicationFiled: April 26, 2011Publication date: June 6, 2013Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Ron Martinus Laurentius Van Lieshout, Roel Penterman

Publication number: 20120266986Abstract: A microfluidic cartridge for placement onto a parallel pneumatic interface plate of a pneumatic instrument is provided. The cartridge includes a three dimensional fluid channel, in which a fluid is to be transported, a flexible membrane that spans a plane and is part of an outer surface of the cartridge. The three dimensional fluid channel is spatially defined in three dimensions by internal walls of the cartridge and by the flexible membrane. The flexible membrane is in a ground state, when no pressure or vacuum is applied to the flexible membrane. However, the flexible membrane is pneumatically deflectable from the ground state perpendicular to the plane of the flexible membrane in two directions when the cartridge is placed onto the parallel pneumatic interface plate.Type: ApplicationFiled: October 6, 2010Publication date: October 25, 2012Applicant: BIOCARTIS SAInventors: Reinhold Wimberger-Friedl, Roel Penterman, Hendrik Halling Van Amerongen, Theodorus Antonius Johannes Loring, Martijn Jochem Van Uden

Patent number: 7847885Abstract: A mechanical structure comprises an element which is moveable by nonmechanical means, such as heat or radiation, between a first state having a first shape and a second state having a second shape different. To this end, the element includes a layer of oriented polymerized liquid crystal which exhibits an anisotropic expansion when subjected to such means. In order to facilitate manufacture the element is positioned on a substrate which has a region of high adhesiveness and a region of low adhesiveness for polymerized liquid crystal. To manufacture such structures a layer of oriented polymerizable liquid crystal is formed on a substrate (201) which is provided with a patterned surface that provides adhesive regions (204) with high adhesiveness to polymerized liquid crystal and nonadhesive regions (203) with low adhesiveness to polymerized liquid crystal.Type: GrantFiled: January 27, 2005Date of Patent: December 7, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Dirk Jan Broer, Christiane Maria Rosette De Witz, Grietje Neeltje Mol, Roel Penterman

Publication number: 20100272608Abstract: Embodiments of the invention relates to a temperature sensor and an analytical device comprising the same. The temperature sensor comprises a carrier (11) with a detection surface (12) on which temperature indicating agents (14) are present and, optionally, at which target components can collect and optionally bind to specific capture elements. An incident light beam (L1) is transmitted into the carrier and evanescent wave excitation is induced at the detection surface (12). The amount of light in the reflected light beam (L2) or an optical, e.g. luminescence response is then detected by a light detector (31). In one example, evanescent light is affected (absorbed, scattered) by temperature indicating agents and optionally target components and/or label particles at the binding surface (12) and will therefore be missing in a frustrated total internal reflected light beam (L2).Type: ApplicationFiled: November 17, 2008Publication date: October 28, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Roel Penterman, Steven Van Lierop, Albert Hendrik Jan Immink, Dirk Jan Broer
