Patents by Inventor Dennis Rosenauer

Dennis Rosenauer 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).

  • Beamforming device testing
    Patent number: 12113583
    Abstract: Improved electrical testing of N-port beamforming devices is provided. For testing, an N:1 electrical network is connected to the N ports of the device under test to provide a single test port. This mode of testing can be used to determine parameters of interest (e.g., far field radiation patterns etc.) of the device under test more rapidly than with antenna range testing or with characterization of each port of the device under test. The N:1 electrical network can be passive or active. The N:1 electrical network can be integrated in a probe head to provide probe array testing of beamforming devices. Alternatively, the N:1 electrical network can be integrated with the device under test to provide onboard testing capability.

  • Method for combining communication beams in a wireless communication system
    Patent number: 6987958
    Abstract: A method provides a technique for optimally combining communication beams. The method forms a plurality of beams from captured signals. One beam is selected as the primary beam while a subset of the others are applied to auxiliary receivers. A digital signal processor weights and combines these primary and secondary beams.
