  • Patent number: 9173613
    Abstract: The present invention relates to a system (1) and method for automatically monitoring the movement activity of a fetus. In order to provide a simple and reliable technique for monitoring the movement activity of a fetus, a method of automatically monitoring the movement activity of a fetus is suggested, the method comprising the steps of: detecting (200) the overall movements of a pregnant female, said overall movements comprising movements of the pregnant female and movements of the fetus; detecting at least one second physiological signal (26) of the pregnant female; and—determining (300) the movement activity of the fetus by analyzing the detected overall movements of the pregnant female, analyzing the at least one second physiological signal (26) of the pregnant female, and discriminating movements of the pregnant female from movements of the fetus depending on the analyzing results.

  • Patent number: 9044170
    Abstract: The present invention discloses a method and signal processing device (620) for analyzing a ballistocardiogram (BCG). The actual energy content of the cardiac part of the BCG in a predefined time window is determined and compared with a reference value. A difference between the actual energy content and the reference energy content exceeding a predefined threshold is indicative of the presence of an arrhythmia in the evaluated part of the BCG because the force exerted by an arrhythmic ventricular contraction, if at all present, is typically substantially smaller than the force exerted by a ventricular contraction of a regular heartbeat. This insight facilitates a more accurate detection of the presence of arrhythmias in a BCG compared to BCG detection schemes based on a heart rate analysis.

  • Patent number: 8583206
    Abstract: The invention refers to a sensor arrangement with at least one sensor and a method for monitoring physiological parameters of a person, a textile fabric and a use of a textile fabric. An sensor arrangement is described that is suited to improve signal quality and suppress noise, for instance in remote capacitive sensing of body parameters. To achieve this, certain textile fabrics are used, preferably integrated into textile used in a bed, e.g. the blanket, the bed cover, or the mattress. These textile fabrics allow for a suppression of electromagnetic interference from external sources and can be arranged to avoid charge build-up during measurements, in particular those caused by movements of the person.

  • Patent number: 8529457
    Abstract: This invention relates to a system and a kit for stress and relaxation management. A cardiac activity sensor (101) is used for measuring the heart rate variability (HRV) signal of the user and a respiration sensor (102) for measuring the respiratory signal of the user. The system contains a user interaction device (103) having an input unit (104) for receiving user specific data and an output unit for providing information output to the user. A processor (106) is used to assess the stress level of the user by determining a user related stress index. The processor is also used to monitor the user during a relaxation exercise by means of determining a relaxation index based on the measured HRV and respiratory signals, the relaxation index being continuously adapted to the incoming measured signals and based thereon the processor instructs the output unit to provide the user with biofeedback and support messages.
