Publication number: 20240055008Abstract: A method and a transmitting node for supporting generation of comfort noise for at least two audio channels at a receiving node. The method is performed by a transmitting node. The method comprises determining spectral characteristics of audio signals on at least two input audio channels and determining a spatial coherence between the audio signals. The spatial coherence is associated with perceptual importance measures. A compressed representation of the spatial coherence is determined per frequency band by weighting the spatial coherence within each frequency band according to the perceptual importance measures. Information about the spectral characteristics and the compressed representation of the spatial coherence per frequency band is signaled to the receiving node for enabling the generation of the comfort noise at the receiving node.Type: ApplicationFiled: October 26, 2023Publication date: February 15, 2024Inventors: Fredrik Jansson, Erik Norvell, Tomas Jansson Toftgård

Patent number: 10309926Abstract: The present invention relates to a device for controlling movement of a fluid sample along a flow path and a corresponding method. The device comprises a working electrode (2) arranged to contact the fluid sample when the fluid sample moves along the flow path, and a reference electrode (3) arranged to contact the fluid sample when the fluid sample moves along the flow path. At least a portion of the reference electrode is arranged abreast of or downstream at least a portion of the working electrode. The present invention is advantageous in that it provides a device wherein a fluid sample may be transported and accurately controlled, with respect to e.g. timing, volumes and flow rates, over greater distances compared to prior art.Type: GrantFiled: September 3, 2013Date of Patent: June 4, 2019Assignee: GINOLIS OYInventors: Fredrik Jansson, Magnus Molin
