  • Patent number: 12225351
    Abstract: A hearing device adapted for being worn at or in an ear of a user, comprises a) an input unit comprising at last two input transducers each for converting sound around said hearing device to an electric input signal representing said sound, thereby providing at least two electric input signals; b) a beamformer filter comprising a minimum processing beamformer defined by optimized beamformer weights, the beamformer filter being configured to provide a filtered signal in dependence of said at least two electric input signals and said optimized beamformer weights; c) a reference signal representing sound around said hearing device; d) a performance criterion for said minimum processing beamformer. The minimum processing beamformer is a beamformer that provides the filtered signal with as little modification as possible in terms of a selected distance measure compared to said reference signal, while still fulfilling said performance criterion.

  • Publication number: 20240201303
    Abstract: In a method of estimating motion of an object and/or magnetic field offsets in a region surrounding the object during a magnetic resonance (MR) imaging scan of the object, superimposed magnetic fields and radiofrequency fields are generated according to an MR sequence for forming images, the MR sequence comprising a train of sequence modules, each sequence module comprising a radiofrequency (RF) excitation segment and an image encoding gradient segment, the MR sequence further comprising a plurality of navigator gradient segments. The navigator signal is acquired along a trajectory in k-space and expressed as a discrete time series comprising a predefined number of complex-valued signal datapoints. The navigator signal acquired in a first sequence module is used to calculate a transformation matrix which relates rotation angles and translational shifts and/or changes of the magnetic field to corresponding changes in navigator signal in a first order approximation.
