  • Publication number: 20110118614
    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.

  • Publication number: 20100324427
    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.

  • Publication number: 20100299840
    Abstract: The invention refers to a sensor arrangement for weight and/or movement sensing in a bed and uses thereof, to a bed and to a method of sensing weight and/or movement of a user in a bed. For the sensing of weight, activity and/or cardiopulmonary performance in a bed, force sensors (6) integrated between a bedframe (2) and a mattress frame (3) are used. The sensors are designed in a way that they can be positioned between the mattress frame and the bedframe without significantly enhancing the height of a mattress bearing surface. Thus, the integration into any bed with bedframe can be easily realized. The measurements do not require any user interaction or even direct contact between user and sensor.

  • Patent number: 7839573
    Abstract: A device for the homogenization of radiation, preferably light, using chirped microlens arrays (cMLA) from the established regular microlens arrays (rMLA), chirped microlens arrays are an arrangement of non-identical lenses in one array. Non-identical means that the lens parameters of the lenses of the array, such as e.g. the radius of curvature, the free diameter, vertex position, and others, can vary from lens to lens or cell to cell. The parameters of each lens or cell can be determined by functions (analytically, numerically), the functions preferably being dependent upon the position of the cell or the lens in the array.

  • Publication number: 20100262026
    Abstract: A method of determining body position uses ECG sensors at fixed positions, not fixed to the patient. The ECG signals recorded from the sensors are used to detect body position, using the variation of ECG potential over the surface of the body. The results may be processed by measuring artefacts related to the angle between the sensors and the heart, in particular the polarity of the QRS complex. The sensors may be fixed on the upper surface of a bed and used to measure sleep position.

  • Publication number: 20090204030
    Abstract: The invention relates to the area of rehabilitation for patients with motor disabilities, especially for hemiplegic patients. With the present invention a long term, e.g. day and night, patient activity monitoring can be established in a home environment. A core idea of the invention is to evaluate the functional use of a limb by determining the synchronicity of the patient's movements depending on the movement's cyclicity. With this approach a reliable assessment of limb usage can be made based on the daily living activities of the patient. With the present invention the progress of rehabilitation can be monitored and guidance can be provided to therapists and patients about the state of the rehabilitation process. It further makes them aware of a lack of limb usage.
