Patents by Inventor Walter R. Strand

Walter R. Strand 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).

  • Patent number: 9329967
    Abstract: Method and related systems are described for navigating through information related to the status of one or more layers of a signal, such as a serial or parallel bus. Information may be displayed by selecting fields within a visual depicted on an oscilloscope or similar measuring instrument. By selecting particular fields, and indicators, different aspects of a layer may be analyzed without the need to have extensive knowledge of the operation of the measuring instrument.
    Type: Grant
    Filed: November 13, 2012
    Date of Patent: May 3, 2016
    Assignee: TEKTRONIX, INC.
    Inventors: Keith D. Rule, Walter R. Strand, Keith A. Olson, Michael J. Wadzita, Steve M. Mishler
  • Patent number: 9178792
    Abstract: Embodiments of this invention include a protocol sensitive visual navigation apparatus, and associated methods, for navigating and relating different protocol levels of a protocol. A test and measurement instrument can include the protocol sensitive visual navigation apparatus, which can facilitate analyzing, searching, and measuring various aspects of the different protocol layers and cross-correlating items from one protocol layer to another protocol layer. The type and characteristics of the analysis is informed by a selected protocol layer. Physical layer signals or events can be correlated to protocol level information, thereby increasing an understanding of the overall protocol and associated protocol layers and events.

  • Patent number: 7920990
    Abstract: Apparatus and methods are provided to allow multiple, possibly overlapping, regions of interest within a frequency spectrum to be defined, and managed. Each of these regions of interest may be selected for further testing or identification. Unselected regions are allowed to collapse into narrow bars so as not to interfere with the selected region. Multiple rows are provided to allow for the definition and selection of overlapping regions of interest. Furthermore, in some embodiments aid is provided for identifying the signal type by providing a list of signal type candidates based upon such parameters as region of interest bandwidth, region of interest center frequency and geographic location.
