His work focuses on developing innovative methods and apparatuses that enhance the understanding and management of spectral regions in various applications.
Latest Patents
One of Schmidt's latest patents is titled "Apparatus and methods of defining spectral regions of interest for signal analysis." This invention provides a framework for defining and managing multiple, possibly overlapping, regions of interest within a frequency spectrum. The design allows for the selection of specific regions for further testing or identification, while unselected regions can collapse into narrow bars to avoid interference. Additionally, the invention aids in identifying signal types by offering a list of candidates based on parameters such as bandwidth and center frequency.
Another significant patent is the "Method for measuring spectral energy interference in a cable." This method establishes a spectrum frequency measurement window with defined start and stop frequencies, along with an amplitude threshold. It involves acquiring data representative of the spectral energy within the window and comparing it against the threshold. If the data indicates the absence of a carrier signal, a display is generated to characterize the interference over the window. This method allows for the establishment of multiple measurement windows to assess different portions of the cable transmission system frequency spectrum.
