Latest Patents

One of Okuno's latest patents pertains to a **digital filter** designed for wireless communication devices. This FIR type digital filter employs an input data converting circuit that samples input data at a rate N times faster than the sampling frequency, fs. It effectively outputs the input data for a 1/N period of a sign interval (T) and "0" for the remainder. The digital filter also features a changeover switch, which toggles between outputs from actual input data and interpolation data. This innovation allows for the effective processing of input shapes resembling rectangular wave pulses, making it ideal for applications in spectrum diffusion communication by elegantly removing unwanted sidebands of digital signals.

Another notable invention by Okuno is the **optical fiber and electrical plug/jack interconnection device**. This connector integrates light signal transmission capabilities within a plug that has a protruding piece, allowing for the simultaneous transmission of electrical and optical signals. The design involves placing optical fibers longitudinally inside the plug, while the jack is equipped with electrodes for electrical signals, and a light-emitting or receiving element. This versatility increases the operational efficiency and potential applications of communication technologies.
