With a total of 2 patents, his work reflects a commitment to advancing technological solutions for various applications.

Latest Patents

One of Tyseer Aboulnasr's latest patents is focused on "Multiresolution Based Power Spectral Density Estimation." This technology describes methods for computing a first power spectral density (PSD) of a signal to determine a first frequency resolution and a first error variance (EV) value associated with the PSD. The first PSD is computed using fewer segments of the signal to achieve a higher resolution, which is linked to a higher EV due to the limited segments used. Subsequently, a second PSD is computed using more segments to determine a second resolution and EV, allowing for the identification of missing frequency variables through an expectation maximization technique.

Another significant patent is for a "Fully Learning Classification System and Method for Hearing Aids." This method enables a hearing aid to continuously learn and adapt to the specific user. It includes a sound environment classification system that tracks and defines sound environment classes relevant to the user. The system redefines these classes based on new environments encountered by the user, ensuring optimal performance of the hearing aid.
