Patent number: 9040938Abstract: A device (1) comprises a source (20) for emitting ultraviolet light, an inlet (30) for letting in fluid to the device (1), an outlet (40) for letting out fluid from the device (1), and means (51, 52) for performing a straightening action of a flow of fluid through the device (1). The flow straightening means comprise at least one flow straightening element (51, 52) having inlet openings for letting in fluid at one side and outlet openings for letting out fluid at another side, wherein each inlet opening is in communication with a plurality of outlet openings, and wherein the element (51, 52) comprises a maze of randomly arranged, interconnected holes. In such a structure, a water element that is moving from one side of the element (51, 52) to another side may take one of various paths, as a result of which variations in inlet conditions can be dampened.Type: GrantFiled: August 12, 2010Date of Patent: May 26, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Paulus Cornelis Duineveld, Eva Mondt, Harko Jan Taekema, Willem Sjouke Wijma, Marc Alexander Pastoors, Wilhelmus Hendrikus Maria Bruggink

Publication number: 20120247342Abstract: A device (100) for heating a food is disclosed. The device (100) comprises at least one heating chamber (110) and a variable-power steam-generating unit (120) configured to generate steam. The variable-power steam-generating unit (120) is fluidly connected with at least one heating chamber (110). On basis of difference between temperature sensed in the device (100) and a predetermined temperature, power of the variable-power steam-generating unit (120) can be adjusted such as to enable attaining a desired heating temperature in the heating process of the device (100).Type: ApplicationFiled: December 22, 2010Publication date: October 4, 2012Applicant: Koninklijke Philips Electronics N.V.Inventors: Peter Hans Van Der Vlis, Willem Sjouke Wijma, Hendrik Klaas Paauw, Alejandro Santalo Barreiro, Theodoor Stolk

Publication number: 20090263095Abstract: The invention relates to a method for integrating a light guide (1) in or onto a support structure (3), wherein said parts (1,3) are molded and wherein during this molding and/or a subsequent cooling down process, shrink behavior of the respective parts (1,3) is controlled in such way that both parts (1,3) shrink incompatibly, at least temporarily and at least near their bordering areas, thereby causing the parts (1,3) to be separated and an air gap (10) to be formed between their respective separation surfaces. Separation of the parts (1,3) can be promoted by making the parts of materials having incompatible melting points and/or incompatible chemical bonding properties. Incompatible shrinkage can be stimulated by appropriate parts design, by applying materials having incompatible shrink behavior and/or by exposing the parts to different molding and cooling down conditions. The invention furthermore relates to a support structure with light guide and a device comprising such a support structure.Type: ApplicationFiled: July 22, 2005Publication date: October 22, 2009Applicant: KONINKLIJKE PHILPS ELECTRONICS, N.V.Inventors: Willem Sjouke Wijma, Lammert Jan Brouwer
