Now that we have DMMs that have QR code displays you don't need to manually transcribe. All joking aside, I have generated telemetry data and displayed via a QR code for exactly this application. Documenting here as prior art so it can't be patented.
A system and method for displaying time series data from any data-generating device as a Quick Response (QR) code, enabling efficient data extraction from video recordings. This invention facilitates the capture and analysis of time series data without manual transcription across a wide range of applications.
Can you publish details (or a link thereto) to solidify the prior art? IIRC, not only the fact of success but also the methods used must be published to establish prior art.
One of the best ways to do this may be to file a Provisional Patent application. It costs $100, and is a write-up of the outline and methods/technology used. The patent office does nothing but leave it in a drawer. If you file a proper patent application referencing it within 365 days, then it becomes part of the new patent and holds your priority date. If you don't then the contents of the Provisional Patent app becomes public domain - now fully and authoritatively documented public domain.
Depends, we managed to OCR all pixels from a standard 128x64pixel OLED. Doing 20 kB/s as a debugging interface was marvelous. Someone smart used the mounting holes on the screen to mount a fixed Finder pattern (the squares in QR Codes), and it was almost fool proof. So Yeah you can easily do seven segment displays now days.
