  • Publication number: 20220071570
    Abstract: A physiological parameter sensing system receives signals from (on includes) a first physiological parameter sensor and an activity monitor. The first physiological parameter signal is used to determine when additional physiological parameter sensing is recommended and an alert is then generated. The alert has characteristics which depend on the type and/or level of activity currently being undertaken by the user. In this way, the alert can be selected so that it is perceived by the user but without being an annoyance.

  • Publication number: 20200335115
    Abstract: An audio encoder comprises a multi-channel receiver which receives an M-channel audio signal where M>2. A down-mix processor down-mixes the M-channel audio signal to a first stereo signal and associated parametric data and a spatial processor modifies the first stereo signal to generate a second stereo signal in response to the associated parametric data and spatial parameter data for a binaural perceptual transfer function, such as a Head Related Transfer Function (HRTF). The second stereo signal is a binaural signal and may specifically be a (3D) virtual spatial signal. An output data stream comprising the encoded data and the associated parametric data is generated by an encode processor and an output processor. The HRTF processing may allow the generation of a (3D) virtual spatial signal by conventional stereo decoders. A multi-channel decoder may reverse the process of the spatial processor to generate an improved quality multi-channel signal.

  • Patent number: 10722183
    Abstract: A method and device are provided for conditioning a sleep signal from a sleep sensor for a sleep monitor. A sleep sensor is configured to sense a physiological signal, such as a cardiac or respiratory signal from a sleeping mammal, such as a human, e.g. an infant or a baby. If the mammal exhibits also (gross) body movement during his sleep, the sensor signal may be clipped. The method and device provide a conditioning of the sleep signal by providing an estimation of the sleep signal instead of the conditioned sleep signal itself when the sensor signal is clipping.

  • Patent number: 10076281
    Abstract: A sleep monitoring device (100) is disclosed for measuring a biophysical variable (131) of a living-being (150), comprising at least two pressure sensors (101-103) spatially arranged in a predefined planar geometry. The living-being rests on the supporting layer (199) contacted by the sensors that generate sensor signals in response to pressure caused by the living being via the supporting layer. A processing unit (110) determines the position of the living-being on the supporting layer based on differences between the sensor signals; a magnitude attenuation factor is determined based on the position of the living-being and a position of a sensor; the biophysical variable is determined from a sensor signal generated by that sensor, including a magnitude correction based on the magnitude attenuation factor. The effect of the invention is that only few sensors are needed to measure a biophysical variable accurately, irrespective of the living-being's position on the supporting layer.
