Patent EP-3462452-A1 (EP)
Inventor: KJEMS ULRIK
IPC: H04M9/08

Abstract: The application relates to a method for audio signal processing. The application further relates to a method of processing signals obtained from a multi-microphone system. The object of the present application is to reduce undesired noise sources and residual echo signals from an initial echo cancellation step. The problem is solved by 
receiving  M  communication signals in frequency subbands where  M  is at least two; 
processing the  M  subband communication signals in each subband with a blocking matrix  (203,303,403)  of  M  rows and  N  linearly independent columns in each subband, where  N >=1 and  N<M,  to obtain  N  target-cancelled signals in each subband; 
processing the  M  subband communication signals and the  N  target-cancelled signals in each subband with a set of beamformer coefficients  (204,304,404)  to obtain a beamformer output signal in each subband; 
processing the communication signals with a target absence detector  (309)  to obtain a target absence signal in each subband; 
using the target absence signal to obtain an inverse target-cancelled covariance matrix of order N  (310,410)  in each band; 
processing the N target-cancelled signals in each subband with the inverse target-cancelled covariance matrix in a quadratic form  (312, 412)  to yield a real-valued noise correction factor in each subband; 
using the target absence signal to obtain an initial estimate  (311, 411 ) of the noise power in the beamformer output signal averaged over recent frames with target absence in each subband; 
multiplying the initial noise estimate with the noise correction factor to obtain a refined estimate  (417)  of the power of the beamformer output noise signal component in each subband; 
processing the refined estimate of the power of the beamformer output noise signal component with the magnitude of the beamformer output to obtain a postfilter gain value in each subband; 
processing the beamformer output signal with the postfilter gain value  (206,306,406)  to obtain a postfilter output signal in each subband; 
processing the postfilter output subband signals through a synthesis filterbank  (207,307,407)  to obtain an enhanced beamformed output signal where the target signal is enhanced by attenuation of noise signal components. This has the advantage of providing improved sound quality and reduction of undesired signal components such as the late reverberant part of an acoustic echo signal. The invention may e.g. be used for headsets, hearing aids, active ear protection systems, mobile telephones, teleconferencing systems, karaoke systems, public address systems, mobile communication devices, hands-free communication devices, voice control systems, car audio systems, navigation systems, audio capture, video cameras, and video telephony.

Abstract: An ultrasonic flow meter (UFM) (100) includes a first (T 1 ) and second ultrasonic transducer (T 2 ) for attaching to a pipe (160), and a transceiver (111, 112) coupled to the transducers by a multiplexer (115). A controller (120) having an associated memory (124) runs an adaptive multi-frequency hopping and coding algorithm that selects ≥ 1 frequency to be hopped within the measured transducer impedance spectrum using a threshold level that selects at least a peak for the phase or a valley for the magnitude, and selects a coding scheme for the chosen frequency to provide a coded frequency sequence. A received signal generated responsive to an ultrasonic signal with the coded frequency sequence into the fluid is decoded, and peak detection is performed on the decoded received signal. The travel time is calculated from the decoded signal, and a speed of the fluid is then determined from the travel time.

Abstract: An active fan-assisted pollution mask makes use of an optical sensor for detecting rotation of the fan and, during fan rotation, the speed of rotation. Breathing cycle detection and/or an automatic turn on and/or turn off function of the fan are implemented based on the analysis of the optical sensor signal. The use of an optical sensor provides a low cost and compact way to implement an automatic control function. It avoids the need for any particular fan design, since the detection is based on optical analysis of the fan rotation rather than analysis of electrical fan signals.
