Latest Patents

Numata's most recent patents include an innovative optical transmission system where a lens converges an optical signal emitted from a light source. This optical signal passes through the lens and enters a multi-mode fiber (MMF). A unique feature of this system is the distance between the vertex of the lens and the input plane of the MMF, which is deliberately set to a value that differs from the lens's focal distance. This design minimizes the effects of mode dispersion, leading to a more affordable optical transmission solution.

Another notable patent revolves around a light-emitting device drive circuit that enhances the signal-to-noise (S/N) ratio of the light output from an LED. In this system, a digital electrical signal is supplied to various components, including a transistor and a current compensation circuit, to generate an injection current. By adjusting the constant-current source, the signal’s integrity is improved, significantly enhancing the S/N ratio of the transmitted signal with band compensation.
