Patent number: 10876964Abstract: The invention relates to a substance determining apparatus and method for determining a substance within a fluid. Particles attach to the substance and bind to a binding surface (30), wherein a particle release curve being indicative of a release of bound particles from the binding surface (30) is determined, and a part of the particle release curve caused by particles bound to the binding surface via a predefined kind of binding is determined based on the temporal behaviour of the particle release curve. The substance within the fluid is determined based on the part of the particle release curve. The substance can therefore be determined based on particles which are bound to the binding surface via a certain kind of binding, i.e. other kinds of binding substantially do not affect the determination of the substance, thereby improving the accuracy of determining the substance.Type: GrantFiled: December 10, 2010Date of Patent: December 29, 2020Assignee: Koninklijke Philips N.V.Inventors: Joannes Baptist Adrianus Dionisius Van Zon, Toon Hendrik Evers, Maatje Koets

Publication number: 20200018689Abstract: The invention relates to a method and a sensor device (100) for evaluating an assay with a sample. During the assay, optical measurements are made at a sensing surface (112), and at least one “homogeneity-image” of the sensing surface (112) is generated. From this image, an “homogeneity-indicator” is determined for at least one region of interest, and the optical measurements are then evaluated in dependence on said indicator. The homogeneity-indicator may for example be a binary value which indicates if an inhomogeneity was detected or not. If an inhomogeneity was detected, all optical measurements may be rejected, only measurements for the involved region of interest may be rejected, or measurements for a selected sub-area of the involved region of interest (ROI) may be rejected.Type: ApplicationFiled: September 25, 2019Publication date: January 16, 2020Inventors: Toon Hendrik EVERS, Derk Jan Wilfred KLUNDER, Jeroen Hans NIEUWENHUIS, Joannes Baptist Adrianus Dionisius VAN ZON

Patent number: 10393735Abstract: The invention relates to a method and a processing device for the processing of a fluid containing interfering particles (C). Magnetic particles (MP) are added to the fluid in a processing chamber and distributed, in part, using a magnetic field to provide a blocking zone (BZ) within the processing chamber to impede or prevent such migration of the interfering particles (C) through the processing chamber. The blocking zone (BZ) hence acts as a filter element by which interfering particles (C) can for example be kept away from a detection region at the surface of the processing chamber.Type: GrantFiled: June 20, 2013Date of Patent: August 27, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Toon Hendrik Evers, Ron Martinus Laurentius Van Lieshout, Joannes Baptist Adrianus Dionisius Van Zon

Patent number: 10079086Abstract: The invention relates to an apparatus (100) and a method for the processing of magnetic particles (MP) provided in a processing chamber (114) with a binding region (116) to which said magnetic particles (MP) can (specifically) bind. Removal of unbound magnetic particles (MP) from the binding region (116) is achieved by first separating them from the binding region (116) by gravitational forces and then moving them further away by magnetic forces. Gravitational forces can for example be generated by tilting the binding region with a tilting unit (156). The prior separation by gravitational forces prevents that unbound magnetic particles (MP) are captured in a cluster with bound magnetic particles.Type: GrantFiled: June 20, 2013Date of Patent: September 18, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Ron Martinus Laurentius Van Lieshout, Joannes Baptist Adrianus Dionisius Van Zon, Toon Hendrik Evers

Patent number: 9841421Abstract: The invention relates to a sensor device (100) and a method for the detection of magnetic particles (1) in a sample chamber (2) with a contact surface (11). The sensor device (100) comprises a sensor unit (120, 130) for detecting magnetic particles (1) in a target region (TR) and/or in at least one reference region on the contact surface. Moreover, it comprises a magnetic field generator (140) for generating a magnetic field that shall guide magnetic particles to the contact surface. With the help of these components, an “auxiliary parameter” is determined that is related to the magnetic particles (1) and/or their movement but that is independent of binding processes taking place in the target region between magnetic particles and the contact surface. The auxiliary parameter may for example be related to the degree of mismatch between the positions reached by the magnetic particles (1) under the influence of a magnetic field and the target region (TR).Type: GrantFiled: November 28, 2011Date of Patent: December 12, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Wendy Uyen Dittmer, Mikhail Mikhaylovich Ovsyanko, Toon Hendrik Evers, Jeroen Hans Nieuwenhuis, Joannes Baptist Adrianus Dionisius Van Zon

Patent number: 9772272Abstract: A substance determining apparatus determines a substance within a fluid where particles, which have attached the substance, are bound to a binding surface. A sensing unit is configured to generate a sensing signal being indicative of at least one of i) a distance between the particles bound on the binding surface and the binding surface, and ii) an in-plane position of the particles bound on the binding surface. A binding discrimination unit is configured to discriminate between different kinds of binding of the particles bound on the binding surface depending on the generated sensing signal. The binding discrimination unit may be a unit for determining the part of the sensing signal being caused by specifically bound particles and for determining the substance based on this determined part of the sensing signal.Type: GrantFiled: September 24, 2010Date of Patent: September 26, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Toon Hendrik Evers, Johannes Joseph Hubertina Barbara Schleipen, Joannes Baptist Adrianus Dionisius Van Zon, Derk Jan Wilfred Klunder, Josephus Arnoldus Hendricus Maria Kahlman, Ron Martinus Laurentius Van Lieshout, Mikhail Mikhaylovich Ovsyanko, Kim Van Ommering

Patent number: 9612239Abstract: The invention relates to a substance determining apparatus (19) for determining a substance within a fluid. A location event determination unit (34) determines location events indicating that a particle, which may have attached the substance, is located in a sensing region and a property of the location events from the sensing signal generated by sensing the sensing region. A location events selection unit (70) selects a part of the location events having a property in a predefined property range, and a substance determination unit (40) determines the substance within the fluid (3) based on the selected part of the location events. This allows tuning the determination of the substance within the fluid to a desired property range, which can relate to a desired kind of bound particles, thereby reducing the influence of unwanted effects on the determination of the substance and, thus, improving the determination accuracy.Type: GrantFiled: February 27, 2012Date of Patent: April 4, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Joannes Baptist Adrianus Dionisius Van Zon, Toon Hendrik Evers, Ron Martinus Laurentius Van Lieshout, Wilhelmina Maria Hardeman, Derk Jan Wilfred Klunder

Patent number: 9488647Abstract: A method detects magnetic particles (1) bound to a binding surface (111) of a sample chamber (112). The detection is made during and/or immediately after the action of an attractive magnetic field. The attractive magnetic field (B) is preceded by a repulsive magnetic field (B) which removes unbound magnetic particles away from the binding surface (111). Due to the attractive magnetic field (B), bound magnetic particles (1) come closer to the binding surface (111), which increases the signal of surface specific detection techniques like frustrated total internal reflection. The signal can be achieved by an attractive magnetic field that is parallel to the binding surface (111) thus inducing the generation of chains between unbound and bound magnetic particles.Type: GrantFiled: October 31, 2012Date of Patent: November 8, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Joannes Baptist Adrianus Dionisius Van Zon, Ron Martinus Laurentius Van Lieshout

Patent number: 9339813Abstract: The invention relates to a substance determining apparatus for determining a substance within a fluid. Particles attach the substance and bind to a binding surface (30), wherein a sensing signal is generated depending on the bound particles. Binding events indicating a binding of a particle on the binding surface (30) are determined from the generated sensing signal, and the substance within the fluid is determined based on the determined binding events. During a procedure of determining a substance within a fluid, particles may bind to the binding surface and may leave the binding surface. Therefore, during this procedure a number of binding events can be determined being much larger than the number of bound particles. The determination of the substance within the fluid can therefore be based on a very large amount of data, thereby increasing the accuracy of determining the substance within the fluid.Type: GrantFiled: December 10, 2010Date of Patent: May 17, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Josephus Arnoldus Henricus Maria Kahlman, Joannes Baptist Adrianus Dionisius Van Zon, Johannes Joseph Hubertina Barbara Schleipen, Derk Jan Wilfred Klunder, Toon Hendrik Evers, Ron Martinus Laurentius Van Lieshout

Patent number: 9250181Abstract: The invention relates to a method and a sensor device (100) for detecting particles (MP) that are bound to the binding surface (12) of a carrier (11). The sensor device (100) comprises a microscope (50) for imaging bound particles (MP) onto an image sensor (53). In order to increase the spatial resolution of the microscope (50), a displacement unit (60,70,80) is provided that can displace the carrier (11) relative to the image sensor (53). The distance of a bound particle (MP) from the binding surface (12) and/or its lateral displacement in reaction to forces can thus be determine with high accuracy. This allows to discriminate specific bindings of large magnetic particles (MP) that are bound to the binding surface (12) via smaller target particles from nonspecific direct bindings.Type: GrantFiled: September 27, 2010Date of Patent: February 2, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Josephus Arnoldus Henricus Maria Kahlman, Joannes Baptist Adrianus Dionisius Van Zon
