Publication number: 20240268712Abstract: The invention relates to a method and apparatus for processing a cyclic physiological signal (30, 40, 52, 53, 54). The method comprises the steps of repeatedly collecting (2) the physiological signal (30, 40, 52, 53, 54) over a time period (31, 32, 33) covering two or more cycles of the cyclic physiological signal (30, 40, 52, 53, 54), wherein a next time period (31, 32, 33) is adjacent to or overlaps with a previous time period (31, 32, 33), extracting values (3, 13) of a set of predefined parameters from the physiological signal (30, 40, 52, 53, 54) within each time period (31, 32, 33) which parameter values characterize the physiological signal (30, 40, 52, 53, 54) within the time period (31, 32, 33), and classifying (4, 14) the physiological signal (30, 40, 52, 53, 54) within each time period (31, 32, 33) based upon the extracted set of predefined parameter values.Type: ApplicationFiled: April 3, 2024Publication date: August 15, 2024Inventors: Bin YIN, Haris DURIC, Geert Guy Georges MORREN, Steven Antonie Willem FOKKENROOD, Jens MUEHLSTEFF

Patent number: 10271751Abstract: 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: GrantFiled: August 12, 2009Date of Patent: April 30, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jens Muhlsteff, Geert Guy Georges Morren, Xavier Louis Marie Antoine Aubert

Patent number: 9675282Abstract: The invention relates to a method and apparatus for determining a respiration of a subject (305) in which, with a single multi-axial accelerometer (310) positioned on a body of the subject (305), accelerometer signals are generated (101) indicative of the acceleration of the subject (305) along different spatial axes, a vector magnitude signal of the acceleration of the subject (305) along the different spatial axes is calculated (102) from the accelerometer signals, a non-respiratory motion contribution to the acceleration along the different spatial axes is identified (103, 203) from the vector magnitude signal, which non-respiratory motion contribution is not caused by the respiration, and a respiration signal indicative of the respiration of the subject is determined (104, 204) by filtering the non-respiratory motion contribution from at least one of the accelerometer signals.Type: GrantFiled: February 7, 2011Date of Patent: June 13, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Geert Guy Georges Morren

Patent number: 9510775Abstract: The invention relates to a motion determination apparatus for determining motion of a moving object, wherein the motion determination apparatus (1) comprises a multi-axial accelerometer (2) for being positioned at the moving object (4), wherein the multi-axial accelerometer (2) is adapted to generate accelerometer signals indicative of the acceleration along different spatial axes. The motion determination apparatus further comprises a motion signal generation unit (3) for generating a motion signal indicative of the motion of the object (4) by combining the accelerometer signals of different spatial axes. The combination of the accelerometer signals of different spatial axes yields a motion signal having a large signal-to-noise ratio, even if an axis is located close to a rotational axis of the movement.Type: GrantFiled: June 2, 2010Date of Patent: December 6, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Geert Guy Georges Morren, Anmin Jin, Bin Jin, Haris Duric, Ronaldus Maria Aarts

Publication number: 20130090566Abstract: The invention relates to a method and a device for detecting a critical physiological state of a patient, especially for detecting a critical hemodynamic event. A set of values of physiological parameters is measured, including the heart rate and the pulse arrival time. On the basis of these measurements, a risk assessment is performed including the allocation of a representation of the measured set of values as a vector in a vector space to a risk level representing the risk of the occurrence of a critical hemodynamic event.Type: ApplicationFiled: June 17, 2011Publication date: April 11, 2013Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Jens Mühlsteff, Geert Guy Georges Morren, Christian Meyer
