20110103625 | AUDIO PROCESSING - An audio processing arrangement ( | 05-05-2011 |
20110246187 | SPEECH SIGNAL PROCESSING - A speech signal processing system comprises an audio processor ( | 10-06-2011 |
20120082335 | EARPHONE ARRANGEMENT AND METHOD OF OPERATION THEREFOR - An earphone arrangement comprises a microphone ( | 04-05-2012 |
20130262101 | NOISE REDUCTION SYSTEM WITH REMOTE NOISE DETECTOR - Noise reduction system with remote noise detector The present invention relates to a noise reduction system with at least one remote noise detector placed close to at least one noise source, which transmits relevant information to a primary device where it is used for noise reduction. Thereby, acoustic signal enhancement can be achieved via the at least one remote noise detector in that a noise estimate is transmitted to controller for noise reduction in the signal obtained from a primary source. | 10-03-2013 |

20140249810 | SIGNAL NOISE ATTENUATION - A noise attenuation apparatus receives a first signal comprising a desired and a noise signal component. Two codebooks ( | 09-04-2014 |
20150338510 | CONTROLLING TRANSMISSION OF PULSES FROM A SENSOR - A sensor such as a presence sensor for use in a lighting system or other system that adapts to information from a plurality of active presence sensors. If transmissions from the active sensors are uncoordinated, the overall detection performance may be adversely impacted (e.g. due to potential cross-interference), which may make sensing over the detection coverage area defined by a single presence sensor (or the like) become unreliable. The disclosure presents protocols for coordinating transmissions in active sensing systems. The invention may be applied to various active modalities (e.g. ultrasound, RF), for example that find applications in indoor and outdoor lighting controls. | 11-26-2015 |
