During my work with the Celadon Research Division of Ellumen Inc., I was a co-inventor on a patent titled “Phase Confocal Method for Near-Field Microwave Imaging” that issued on October 8, 2019. This is the fifth patent I have been a co-inventor on.  If you are interested in learning more about my prior four patents see the post titled “Description of Three Patents Named Co-Inventor On Assigned to Ellumen Inc” and also the post titled “Microwave Imaging Device Patent Named Co-Inventor on Assigned to Ellumen Inc.

This patent builds upon work presented in 2017 in a paper titled paper titled “A Phase Confocal Method for Near-Field Microwave Imaging” published in IEEE Transactions on Microwave Theory and Techniques. The patent describes a frequency domain based method that uses electromagnetic waves transmitted and received by antennas to estimate a phase shift caused by an object in the path of the electromagnetic waves. The phase is reversed to allow for an image to be constructed.

The patent provides protection for a system and method for producing microwave images that calculates phase shifts based on a propagation distance from a receiver to a transmitter, compensating a phase using the phase shift, and calculating a variance of the phase shift using an inverse summation. Further, the patent provides protection for a method for producing images that calculates phase shifts based on a propagation distance from a receiver to a transmitter, compensating a phase using the phase shift, and utilizing complex-number detected microwave signals as unit vectors when producing an image. Additionally, the patent provides protection for a method for producing images that calculates phase shifts based on a propagation distance from a receiver to a transmitter and compensating a phase using the phase shift along with information from a phase change in a connector on both the transmitter and receiver end and a phase change in the transmitter and receiver. The patent also provides protection for methods for utilizing multiple frequencies. The high efficiency of the method allows for real-time imaging.

Below is a patent certificate that was created to celebrate the accomplishment of having the patent granted. This is the first patent I have had issued since after the USPTO celebrated the issuance of 10 million patents and changed the patent cover design.

On April 7, 2019, I visited the cherry blossoms in the Tidal Basin along with the National Museum of African Art and the National Portrait Gallery. Below are some pictures taken while visiting the cherry blossoms, national mall, and museums of the Smithsonian Institution mentioned above in Washington, D.C.

On March 31, 2019, I walked around the National Mall in Washington D.C. and visited the cherry blossoms in the Tidal Basin. This was one day before the predicted peak bloom this year when 70% of the blossoms of the Yoshino cherry trees that surround the Tidal Basin are open. I also went inside the West Building of the National Gallery of Art, the Archives of American Art Lawrence A. Fleischman Gallery, and the National Portrait Gallery. Below are some pictures taken in Washington D.C. while visiting the cherry blossoms and museums mentioned above.

On March 24, 2019, I walked around the National Mall, the Smithsonian Institution Building (the Castle), and the U.S. Capital in Washington D.C. I also went inside the National Postal Museum and the East Building of the National Gallery of Art. Below are some pictures taken in Washington D.C. while outside and inside these two exhibits.

On Washington’s Birthday also known as President’s Day, on February 18, 2019, I attended the George Washington Birthday Parade in Alexandria, VA, and the day before I visited the National Portrait Gallery, which is a part of the Smithsonian Institution, in Washington D.C. The George Washington Birthday Parade marches through Old Town Alexandria and is billed as the largest George Washington Birthday Parade in the U.S. While at the National Portrait Gallery I visited the Hall of Presidents which has portraits of nearly all American presidents. Below are some pictures I took while over Presidents’ Day weekend in February, 2019.
