Patent number: 8314412Abstract: A method of manufacturing a grid (1) for selective transmission of electromagnetic radiation, particularly X-ray radiation, is proposed. The method comprises: providing a support element (3) having self-supporting stability, wherein the support element (3) is made with a material which essentially absorbs no electromagnetic radiation to be selectively transmitted through the grid; applying a metal layer (5) at a surface of the support element (3); and building a selective transmission structure (7) at a surface of the metal layer (5) with a material which absorbs electromagnetic radiation to be selectively transmitted through the grid, wherein the transmission structure is build using selective laser sintering.Type: GrantFiled: October 7, 2009Date of Patent: November 20, 2012Assignee: Koninklijke Philips Electrnics N.V.Inventor: Geroen Vogtmeier

Publication number: 20110144456Abstract: A method for monitoring the blood pressure of a patient, comprising the following steps: determining a pulse arrival time signal from the patient 2 based on the pulse wave velocity method; determining an accelerometer signal from the patient 2; and triggering an additional measure or deriving a blood pressure value, taking into account the pulse arrival time signal and a DC component of the accelerometer signal. In this way, a possibility for monitoring the blood pressure of a patient is provided with which false alarms and/or unnecessary additional cuff-based blood pressure measurements can be avoided.Type: ApplicationFiled: August 12, 2009Publication date: June 16, 2011Applicant: KONINKLIJKE PHILIPS ELECTRNICS N.V.Inventors: Jens Muhlsteff, Geert Guy Georges Morren, Xavier Louis Marie Antoine Aubert

Publication number: 20090325164Abstract: The invention relates to a microelectronic sensor device and a method for the investigation of biological target substances (20), for example oligonucleotides like DNA fragments. In one embodiment, the device comprises a reaction surface (RS) to which target specific reactants (10) are attached and which lies between a sample chamber (SC) and an array of selectively controllable heating elements (HE). The temperature profile in the sample chamber (SC) can be controlled as desired to provide for example conditions for a PCR and/or for a controlled melting of hybridizations. The reactant (10) and/or the target substance (20) comprises a label (12) with an observable property, like fluorescence, that changes if the target substance (20) is bound to the reactant (10), said property being detected by an array of sensor elements, for example photosensors (SE).Type: ApplicationFiled: May 24, 2007Publication date: December 31, 2009Applicant: KONINKLIJKE PHILIPS ELECTRNICS N.V.Inventors: Erik Robert Vossenaar, Marc Wilhelmus Gisbert Ponjee, Hendrik Roelof Stapert, Mark Thomas Johnson

Publication number: 20080044027Abstract: A secure solution is provided to the problem of secret key agreement. In particular, a method of reliable forward secret key sharing is disclosed between two legitimate correspondents whose profiles match sufficiently. The invention relies on a physical random function, sometimes referred to as a physical unclonable function (PUF) to provide a secure solution to the problem of secret key agreement. In one embodiment, a one-pass protocol is introduced based on Reed-Solomon codes leading to an unconditionally secure solution. In a further embodiment, the solution of the first embodiment is improved upon by providing a conditionally secure solution based on a pseudo random family of functions. In a still further embodiment, a two-pass protocol is introduced which is used exclusively for purposes of identification and authentication. In accordance with the principles of the two-pass protocol, two communications are required and unlike the one-pass protocol, the second correspondent selects the secret key K.Type: ApplicationFiled: October 28, 2004Publication date: February 21, 2008Applicant: KONINKLIJKE PHILIPS ELECTRNICS, N.V.Inventor: Marten E.

Publication number: 20070057905Abstract: A system implements a method of activating an electrophoretic display (10). First, the system provides at least one image-dependent data frame (70) including pixel data (72) and a data frame time (74). Second, the system determines a blanking frame (80) including a blanking frame time (84) based on the data frame time. Third, the system addresses the electrophoretic display (10) based on the pixel data (72), the data frame time (74), and the blanking frame (80) to reduce vertical crosstalk.Type: ApplicationFiled: August 30, 2004Publication date: March 15, 2007Applicant: KONINKLIJKE PHILIPS ELECTRNICS N.V.Inventors: Mark Johnson, Guofu Zhou, Jan Kamer

Publication number: 20060273728Abstract: A high-pressure gas discharge (HID, high intensity discharge) lamp is described, having a discharge vessel (1) that contains a metal that is applied at least to parts of those regions of the feedthroughs and/or walls of the discharge vessel (1) at which condensation of ingredients of the gas filling may occur as a result of a temperature sink that occurs when the lamp is in a state of operation. In this way, it is possible to at least largely prevent not only chemical interactions between ingredients of the gas filling (particularly the metal halides) and the relevant regions of the feedthroughs or walls at which, due to the lower temperature of these regions, the ingredients condense, but also losses of ingredients of this kind from the gas filling. This in turn means that there is no risk of any damage to the lamp or of any degradation of its lumen maintenance.Type: ApplicationFiled: September 1, 2004Publication date: December 7, 2006Applicant: Koninklijke Philips Electrnics N.V.Inventors: Matthias Born, Ulrich Niemann
