Title: Takashi Oshimi: Optical Measurement and Data Display Innovations.

Introduction. Takashi Oshimi is an inventor based in Isehara, Japan, whose patent work includes technologies for optical-fiber measurement and the presentation of measurement data. He is associated with Anritsu Corporation and holds 4 patents.

Latest Patents. One of Oshimi’s latest patents describes an optical time-domain reflectometer that measures an optical fiber at multiple wavelengths in sequence and displays the resulting waveforms alongside event information. The system generates wavelength-specific light pulses, detects reflected light, stores the resulting signals, and identifies the positions and characteristics of events. Its display separates waveform data from a corresponding event list, helping users compare measurements across wavelengths.

Another patent concerns a measurement data display apparatus. It presents fundamental measurement data on a main screen and, when prompted by a key operation, opens a secondary screen containing menus for additional data. The layout associates smaller menu items with function keys and allows larger menu categories to be selected through another key, providing an organized way to navigate measurement information.

Career Highlights. Oshimi’s patent portfolio reflects a focus on measurement instruments and user interfaces. His inventions address both the acquisition and analysis of optical signals and the clear presentation of technical data.

Collaborations. Oshimi is associated with Anritsu Corporation. His listed coworkers include Norio Nakayama and Shigeo Hori.

Conclusion. Takashi Oshimi’s patents highlight practical innovations in optical-fiber testing and measurement-data display, supporting the collection, interpretation, and navigation of technical information.
