October 12th, 2021. Non-provisional utility patent, application number 17/498,937, titled “Photon Sensor”, is filed with the United States Patent and Trademark Office (USPTO). This novel proprietary technology describes, among other things, perovskite-graphene pixels that have high sensitivity and minimal electrical pixel crosstalk, with an extremely low bias potential. A one-step pixel patterning method is described which reduces the cost of fabrication. Lastly an interchangeable upgradeable sensor for the X-ray camera is detailed, which allows for a yearly subscription based business model and gives customers the latest technology year-after-year.
