Publication number: 20240060971Abstract: Methods and systems are provided for compensating for gravitational and fluid composition effects on a magnetic biosensor system. In one example, a sensor system includes a sample container configured to receive a sample containing an analyte to be tested, the sample container comprising a detection surface and a plurality of signal generating elements in the sample container, wherein the detection surface comprises a binding surface, which has been partially functionalized with capture elements that can bind, directly and/or indirectly, the analyte and/or the plurality of signal generating elements. The sensor system further includes a memory storing instructions executable by a processor to obtain background data comprising sensor signals from one or more background regions of the detection surface, obtain sample data comprising sensor signals from the binding surface, and perform a correction of the sample data based on the background data.Type: ApplicationFiled: December 9, 2021Publication date: February 22, 2024Applicant: Siemens Healthineers Nederland B.V.Inventor: Alexander van Reenen

Patent number: 11519845Abstract: The present invention relates to a device (10) for use in fluid sample analysis. It is described to position (310) a top part (20) of the device (10) adjacent to a base part (30) of the device so as to define a fluidic receiving region in between, the top part being provided with a through opening fluidly connected to the fluidic receiving region, and the bottom part being provided with a radiation window adjacent to the fluidic receiving region. A fluidic sample is supplied (320) through the opening (24). The fluidic sample is moved laterally (330) in the fluid receiving region without the use of an intermediary membrane between the top part and the base part. A radiation is emitted (340) to the fluid receiving region. A radiation is detected (350) that is reflected by the device. A presence of the fluidic sample is determined (360) on the basis of a measured reflectance value based on the detected radiation.Type: GrantFiled: May 16, 2017Date of Patent: December 6, 2022Assignee: Siemens Healthineers Nederland B.V.Inventors: Alexander Van Reenen, Markus Hendrikus Van Roosmalen, Hendrik Sibolt Van Damme

Publication number: 20190302134Abstract: The disclosure pertains to determining a melatonin level in a biological sample of a subject with a determination system. The determination system comprises a melatonin analyzer, a temperature sensor, and a controller. The method comprises providing a first biological sample from the subject to the melatonin analyzer; generating one or more output signals conveying information related to a temperature of the analyzer; controlling the temperature of the analyzer based on the output signals to be within a pre-determined temperature range, such that responsive to the temperature of the analyzer being outside the pre-determined temperature range, the controlling comprises cooling and/or heating the analyzer to bring and maintain the temperature within the pre-determined temperature range; and responsive to the temperature of the analyzer being within the pre-determined temperature range, facilitating determination of a melatonin level of the first biological sample with the analyzer.Type: ApplicationFiled: March 20, 2019Publication date: October 3, 2019Inventors: LAURENT BROUQUEYRE, MANUEL LAURA LAPOINT, ALEXANDER VAN REENEN, MARKUS HENDRIKUS VAN ROOSMALEN

Publication number: 20180372759Abstract: Disclosed is a method for determining onset of a sleep-related analyte. The method includes: obtaining first surrogate measurement(s) of a sleep-related analyte based on signal(s) obtained via sensor(s) during a first time period of observation; obtaining second surrogate measurement(s) of the sleep-related analyte based on signal(s) obtained via sensor(s) during a second time period of observation; determining a first surrogate function or value based on the first surrogate measurement(s) and a second surrogate function or value based on the second surrogate measurement(s); and predicting an onset of the sleep-related analyte for a first individual based on the first surrogate function or value and the second surrogate function or value such that the prediction of the onset of the sleep-related analyte is performed without determining an absolute concentration value for the sleep-related analyte.Type: ApplicationFiled: June 26, 2018Publication date: December 27, 2018Inventors: ALEXANDER VAN REENEN, MARKUS HENDRIKUS VAN ROOSMALEN, LAURENT BROUQUEYRE, PETRUS JOHANNES WILHELMUS VAN LANKVELT

Patent number: 9183657Abstract: A system and method may be provided to access images through a camera service, where the images are generated by a non-sensor image source, such as a composition manager. The system may include the camera service and the non-sensor image source. The non-sensor image source may generate a processed image from a source other than a sensor. The camera service may provide the processed image generated by the non-sensor image source to an image consuming application.Type: GrantFiled: October 1, 2014Date of Patent: November 10, 2015Assignee: 2236008 Ontario Inc.Inventors: Etienne Belanger, Adrian Nita, Adrian Boak, Michael Alexander Van Reenen, Neil John Graham
