Patent number: 9520120Abstract: A system for generating a control signal comprises a data propagator (9) for propagating acoustic sensor array data relating to a set of acoustic measurements at a set of sensor positions covering an aperture towards a set of propagated positions to obtain propagated data relating to the set of propagated positions. A control signal generator (2) is arranged for generating a control signal based on the propagated data. The control signal generator (2) comprises a data analyzer (1) for analyzing the propagated data in a spatial frequency domain. The data propagator (9) is arranged for propagating the sensor array data in real-time and the control signal generator (2) is arranged for generating the control signal in real-time.Type: GrantFiled: July 27, 2011Date of Patent: December 13, 2016Assignees: TECHNISCHE UNIVERSITEIT EINDHOVEN, SORAMA HOLDING B.V.Inventors: Rick Scholte, Ines Lopez Arteaga, Henk Nijmeijer

Patent number: 9084045Abstract: An acoustic transducer assembly is disclosed. It comprises a layer of support material. An electric circuit is integrated with the layer of support material. A plurality of transducers are mounted on the layer of support material to form at least part of an array of transducers A recess or aperture is provided between a pair of the transducers of the array of transducers. The recess or aperture can comprise a recess or aperture of the support material between a pair of transducers of the plurality of transducers mounted on the layer of support material. The layer of support material can be rigid or flexible. A rigid support can be used for supporting at least one transducer of the plurality of transducers.Type: GrantFiled: December 6, 2010Date of Patent: July 14, 2015Assignee: SORAMA HOLDING B.V.Inventor: Rick Scholte
