  • Publication number: 20190357851
    Abstract: A data processing device (100, 200) is disclosed for extracting a desired vital signal containing a physiological information component from sensor data that includes time-dependent first sensor data (PPG1) comprising the physiological information component and at least one motion artifact component, and that includes time-dependent second sensor data that is indicative of a position, a velocity or an acceleration of the sensed region as a function of time. A decomposition unit (104, 204) decomposes the second sensor data into at least two components of decomposed sensor data and, based on the decomposed second sensor data, provides at least two different sets of motion reference data in at least two different motion reference data channels. An artifact removal unit (106, 206) determines the vital signal formed from a linear combination of the first sensor data and the motion reference data of at least one two of the motion reference data channels.

  • Publication number: 20190159688
    Abstract: The present invention relates to a device (10) for determining an arterial compliance of a subject (12). The device (10) comprises an inflatable cuff (14), a pressure sensor (18) which is configured to sense a pressure signal (52) that is indicative of a pressure within the cuff (14), a second sensor (20) which is at least partly integrated in the cuff (14) and configured to sense a second signal (56) that is responsive to expansions and contractions of the cuff (14) caused by a pulsating blood flow in an artery (50) of the subject (12), and a processing unit (22). The processing unit is configured to determine based on said part of the pressure signal (52) a pulse pressure of the subject (12), to determine based on said part of the second signal (56) an arterial volume change of the artery (50) of the subject (12) during at least one cardiac cycle, and to determine the arterial compliance of the subject (12) based on pulse pressure and the arterial volume change.

  • Publication number: 20190008458
    Abstract: A data processing device (100, 200) determines heart rate information regarding a subject of interest (605) from time-dependent sensor data (110) that includes physiological sensor data (114) comprising a heart beat component and at least one motion artifact component, and that further includes motion sensor data (116). A reconstruction unit receives artifact-removed physiological sensor data (130) and decomposes it into a plurality of artifact-removed physiological sensor data components (145) with associated component amplitudes, and provides reconstructed heart beat component data (150) as a combination of a component subset of at least two of the artifact-removed physiological sensor data components (145) of highest component amplitudes.

  • Patent number: 10034639
    Abstract: An optical vital signs sensor is provided which comprises at least one light source with a primary and a secondary light unit and a photo detector, a motion sensor configured to detect a motion of a user, a periodicity metric unit to analyze an output signal of the at least one motion sensor to detect a periodicity in its output signal and a control unit configured to control an operation of the at least one primary and secondary light unit and to activate the at least one secondary light unit in addition to the at least one primary light unit when the periodicity metric unit does not detect a periodicity in the output signal of the motion sensor.

  • Patent number: 9765516
    Abstract: A room divider (100) for dividing a room into two sub-portions (R1, R2) and for attenuating sound (S1, S2) travelling between the two sub-portions is provided. The room divider comprises hollow cylindrical elements (110) arranged periodically for dividing the room into the two sub-portions. At least some of the hollow cylindrical elements have a cylindrical shell (111) with at least one slit (112) extending in an axial direction (120) of the shell. The shell extends continuously along the perimeter of the corresponding hollow cylindrical element from one side (113) of the at least one slit to another side (114) of the at least one slit. Each of the at least one slit faces in a local elongation direction (130) of the room divider for increasing acoustic symmetry with respect to the two sub-portions. The use of destructive interference and resonance to attenuate sound allows for a less bulky/heavy acoustically absorbing room divider.

  • Publication number: 20170215747
    Abstract: An optical vital signs sensor embodied as a PPG sensor is provided. The optical vital signs sensor comprises a light source to generate light at at least two wavelengths, a photo detector unit configured to detect the light of the at least two wavelengths, a contact surface to be placed against a skin of the user and an off-skin detection unit configured to detect whether the contact surface is in contact with the skin of the user based on output signals of the photo detector at the at least two wavelengths.
