Patents by Inventor Eira Tuulia Seppälä

Eira Tuulia Seppälä has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Generation of differential signals
    Patent number: 9319043
    Abstract: The invention relates to an apparatus comprising a differential driver module configured to generate at least one differential signal having steep rise and fall times for at least partially reducing common-mode noise. The invention also relates to a method for causing the differential driver to generate the signal and a system comprising the differential driver and a conductor module for transmission of the generated differential signal. A computer program for performing the method and a computer-readable medium is also part of the invention.
    Type: Grant

  • Apparatus for spectrum sensing and associated methods
    Patent number: 8421440
    Abstract: In one embodiment, an apparatus comprises a nano-scale spectrum sensor configured to be electromagnetically excitable at a predetermined frequency based on received ambient electromagnetic radiation. The apparatus is also configured to be able to use this excitation of the nano-scale spectrum sensor to thereby determine ambient electromagnetic radiation spectrum usage.
