Latest Patents

Maeda’s listed patents address practical challenges in printing and secure data communication.

“Thermal Print Head and Thermal Printer Provided with Wireless Communication Function Using Such Thermal Print Head” describes a thermal printhead that prints on RFID tags containing a coil antenna and memory. The printhead incorporates a coil antenna as part of a wireless data transmitter-receiver, enabling communication with the tag.

“IC Card Having a Display for Displaying a Response State” describes an IC card that indicates the outcome of data communication. An abnormality determination circuit checks how data has been processed. If data is written successfully, the card displays a normal-completion indication. If an error occurs but the data is recovered using protected memory, the card displays a recovery indication. If recovery fails, it displays a communication-abnormality indication.
