Latest Patents

One of Yasuhiko Ishida's latest patents is an apparatus for detecting rotational displacement information. This innovative angular division apparatus utilizes Doppler pulses to divide a rotating object into multiple areas. It features an optical head that applies a beam from a light source to the rotating object, detecting Doppler pulses based on the frequency shift of the scattered light. The counting unit then counts these pulses to determine the number of pulses for one revolution, allowing for precise angular division.

Another notable patent is related to a velocimeter, which includes a light source that irradiates light onto an object to be measured. The device features a light-receiving element that captures scattered light and outputs a signal. A signal processing circuit processes this signal to obtain velocity information. The velocimeter is equipped with a bandpass filter that activates when the object's moving velocity is low, ensuring accurate measurements.
