Publication number: 20190167207Abstract: 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.Type: ApplicationFiled: April 6, 2017Publication date: June 6, 2019Inventor: ERIK GOSUINUS PETRUS SCHUIJERS

Patent number: 10076281Abstract: 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.Type: GrantFiled: November 27, 2014Date of Patent: September 18, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Igor Berezhnyy, Erik Gosuinus Petrus Schuijers, Pedro Miguel Fonseca

Publication number: 20180151185Abstract: 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.Type: ApplicationFiled: January 8, 2018Publication date: May 31, 2018Inventors: Dirk Jeroen BREEBAART, Erik Gosuinus Petrus SCHUIJERS, Arnoldus Werner Johannes OOMEN

Patent number: 9973871Abstract: An audio renderer comprises a receiver (801) receiving input data comprising early part data indicative of an early part of a head related binaural transfer function; reverberation data indicative of a reverberation part of the transfer function; and a synchronization indication indicative of a time offset between the early part and the reverberation part. An early part circuit (803) generates an audio component by applying a binaural processing to an audio signal where the processing depends on the early part data. A reverberator (807) generates a second audio component by applying a reverberation processing to the audio signal where the reverberation processing depends on the reverberation data. A combiner (809) generates a signal of a binaural stereo signal by combining the two audio components. The relative timing of the audio components is adjusted based on the synchronization indication by a synchronizer (805) which specifically may be a delay.Type: GrantFiled: January 8, 2014Date of Patent: May 15, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jeroen Gerardus Henricus Koppens, Arnoldus Werner Johannes Oomen, Erik Gosuinus Petrus Schuijers

Publication number: 20170125030Abstract: An encoder generates data representing an audio scene by a first downmix and data characterizing audio objects. In addition, a direction dependent diffuseness parameter indicative of a degree of diffuseness of a residual downmix is provided where the residual downmix corresponds to a downmix of audio components of the audio scene with the audio objects being removed. A rendering apparatus comprises a receiver receiving the data from the encoder. A circuit generates signals for a spatial speaker configuration from the audio objects. A transformer generates non-diffuse sound signals for the spatial speaker configuration by applying a first transformation to the residual downmix and another transformer generates signals for the spatial speaker configuration by applying a second transformation to the residual downmix by applying a decorrelation to the residual downmix. The transformations are dependent on the direction dependent diffuseness parameter. The signals are combined to generate an output signal.Type: ApplicationFiled: January 18, 2017Publication date: May 4, 2017Inventors: JEROEN GERARDUS HENRICUS KOPPENS, ERIK GOSUINUS PETRUS SCHUIJERS, ARNOLDUS WERNER JOHANNES OOMEN, LEON MARIA VAN DE KERKHOF
