Latest Patents
One of Oprea's latest patents is the Passive Transponder. This invention relates to an electronic identification system that includes one or more transponders storing identification and other information in memory. The system utilizes readers that capture information from the transponders and can write new information to them. Communications between transponders and readers are accomplished using radio frequency signals. This invention is particularly useful in automatic fare collection systems, where transponders, often in the form of thin cards, replace printed tickets and eliminate the need for cash exchange. The system allows for simultaneous identification of numerous transponders by one reader, enables selective programming of transponders, exhibits fast transaction speeds, and ensures exceptional data storage integrity.
Another significant patent is the Microwave Integrated Tuned Detector. This invention integrates two circular patch antennas with a detector diode. The design combines high impedance at the edge of the circular patch antenna with 180 degrees out of phase electric fields at diametrically opposite points. This configuration matches the RF impedance of a zero or small DC bias diode, resulting in a simple, high-sensitivity narrow-band microwave integrated detector.
