Latest Patents
One of his latest inventions is a code division multiple access apparatus. This apparatus is designed for high-speed synchronization and features a simple construction. It also achieves reduced electric power consumption during standby. The system utilizes a surface acoustic wave (SAW) matched filter to detect specific patterns in received signals, generating a synchronization signal after a set time. Additionally, an orthogonal PN code generator and a carrier generator work together to modulate the received signal, returning it to its original baseband data form.
Another significant patent is the radio IC card system. This system includes an IC card and a toll collector. When an automobile equipped with the IC card passes through a tollgate, the toll collector transmits a radio signal that is spread modulated using a pseudorandom noise (PN) code. The IC card's antenna receives this signal, and a SAW correlator extracts the PN code, outputting a peak signal. This peak signal is accumulated, and when it exceeds a certain threshold, it activates a relay switch to supply power to the data communication unit. The IC card then transmits its identification code and tollgate records to the toll collector.
