Latest Patents

Ishida is credited with 1 patent: “Optical Pulse Test Device and Optical Pulse Test Method.” The invention uses OTDR waveform measurements taken at multiple pulse widths. It analyzes event levels, losses, and return losses, then selects a pulse width that meets a required signal-to-noise ratio at each event’s start and end points. By integrating cumulative loss using the selected pulse widths, the device produces an analysis result designed to support reliable optical-fiber testing.

Career Highlights

Ishida’s listed patent reflects work on improving how optical pulse measurements are analyzed. The approach combines measurements at different pulse widths to address signal-to-noise requirements while calculating cumulative loss across detected events.
