Latest Patents

One of May's latest patents is titled "Systems and methods for printing patterns using near infrared upconverting inks." This invention focuses on utilizing upconverting inks to produce highly-resolved patterns for various applications, including security. The technology involves the use of sols (inks) and printing processes that create well-defined printed features made of polymers infused with luminescent upconversion nanocrystals. The resulting patterns can display defined shapes, text characters, and various images.

Another notable patent is the "Reader apparatus for upconverting nanoparticle ink printed images." This invention provides an improved system and method for reading the upconversion response from nanoparticle inks. The system directs a near-infrared excitation wavelength at a readable indicia, generating a near-infrared emission wavelength from the upconverting nanoparticle inks. It includes a short pass filter to filter the excitation wavelength and a camera that captures the emission wavelength. An integrated circuit processes the signal, allowing for manipulation, decoding, and display of the output.
