Latest Patents

One of Yuji Ishii's latest patents is an optical receiver and light receiving method. This optical receiver is designed to receive coherent light and includes an amplitude adjuster, a signal processor, and a controller. The amplitude adjuster modifies the amplitude of an input signal to produce an analog signal. The signal processor then generates a digital signal from this analog output, extracts clock components, and establishes synchronization to process the data components effectively. The controller plays a crucial role by adjusting the amplitude of the analog signal before and after synchronization.

Another notable patent is related to an electronic device and current monitoring method. This device features a detection circuit that measures the voltage difference across a wiring portion of a power supply. It includes a current supply circuit that provides a pilot current, which is less than the main current, to the power supply wiring. The control circuit manages the supply of the pilot current and calculates the wiring resistance and main current based on the voltage differences observed during operation.
