Patent number: 11519900Abstract: A method for synchronizing data for gas samples with volatile organic compounds. The data includes chromatographic data indicative of molecule retention times. The method includes identifying or selecting marker molecules and clustering the plurality of gas samples into a plurality of clusters according to a clustering criterion. Next, a first correction of retention time deviations is performed on the data for the gas samples between clusters by using the marker molecules as anchor points to provide a coarse reduction of retention time deviations between the data. Finally, a second correction of retention time deviations is performed on the data, so as to further reduce retention time deviations between the data. The method reduces significant retention time deviations to allow, e.g., breath sample fingerprints obtained by different equipment at different times to be compared in one database for use on a digital platform.Type: GrantFiled: January 17, 2018Date of Patent: December 6, 2022Assignee: Koninklijke Philips N.V.Inventors: Johannes Weda, Teunis Johannes Vink, Hugo Hubertus Knobel, Tamara Mathea Elisabeth Nijsen

Publication number: 20210356453Abstract: A method (RT_A) for synchronizing data for a plurality of gas samples, e.g. breath samples, with volatile organic compounds. The data comprises chromatographic data indicative of molecule elution times, and preferably also mass spectrography data. The method comprises identifying or selecting (I_MM) marker molecules, e.g. 5-20 molecules, preferably easily identifiable molecules for each of the plurality of gas samples, and clustering (CL) the plurality of gas samples into a plurality of clusters according to a clustering criterion, e.g. including additional information such as time of obtaining the data and/or analyzing equipment used. Next, a first correction of retention time deviations (P_C1) is performed on the data for the gas samples between clusters by using the marker molecules as anchor points, so as to provide a coarse reduction of retention time deviations (d) between the data for the gas samples.Type: ApplicationFiled: January 17, 2018Publication date: November 18, 2021Inventors: JOHANNES WEDA, TEUNIS JOHANNES VINK, HUGO HUBERTUS KNOBEL, TAMARA MATHEA ELISABETH NIJSEN

Publication number: 20120123288Abstract: A method and apparatus of determining the level of exhaled nitric oxide (NO) is disclosed. The method involves measuring the level of exhaled NO (34) and the corresponding exhalation flow rate in one or more exhalations (30, 32) of a tidal breathing manoeuvre performed by a subject. The data is used with a model describing the flow dependence of exhaled NO to derive a value for exhaled NO corresponding to a fixed flow rate, especially to an exhaled NO level corresponding to a fixed flow rate of 50 ml/s. During the manoeuvre a variation in flow restriction (31) may be applied so as to vary the overall flow rate of exhalation. The method offers a simple and quick way to determine exhaled NO levels with good accuracy and is suitable for use with children.Type: ApplicationFiled: July 23, 2010Publication date: May 17, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Hans Willem Van Kesteren, Teunis Johannes Vink, Nicolaas Petrus Willard

Publication number: 20090128819Abstract: Nitrogen-containing compounds are detected by chemically converting (210) them to nitrogen dioxide, and detecting (10) the amount of nitrogen dioxide. A semiconductor laser or light emitting diode (132) provides a modulated light (131) in the blue-violet-green wavelength range and a narrow bandwidth photo-acoustic sensor (10) detects the standing waves produced by the absorption of the light by the nitrogen dioxide. The photo-acoustic sensor (10) uses a resonant cavity (161, 182a-b) with a resonant frequency that corresponds to the modulation frequency of the light (131). For detecting nitric oxide, a surface chemical oxidation unit (210) is preferably used to convert the nitric oxide to nitrogen dioxide, using, for example potassium permanganate (KMnO4) filter, or a platinum (Pt) catalyst unit (260).Type: ApplicationFiled: April 25, 2006Publication date: May 21, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: HANS WILLEM VAN KESTEREN, TEUNIS JOHANNES VINK, NICOLAAS PETRUS WILLARD
