Title: Keiko Makie: Innovator in Neuromagnetic Diagnosis
Introduction
Keiko Makie is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of neuromagnetic diagnosis through her innovative patents. With a total of 2 patents, her work has garnered attention in both academic and industrial circles.
Latest Patents
One of her latest patents is a weak magnetic field measuring system using a dc-SQUID magnetometer. This multichannel system is designed for neuromagnetic diagnosis and includes several dc-SQUID magnetometers. The system features bias current setting circuits that detect an even harmonic component of the output across the terminals of the corresponding SQUID. These circuits automatically adjust the DC bias current to the SQUID, ensuring that the level of the component reaches a predetermined value. Additionally, the system includes circuitry for equalizing the magnetic flux detection sensitivities of the dc-SQUID magnetometers. It also has abnormal operation detecting circuits that produce outputs when the level of the corresponding even harmonic component falls below a certain threshold.
Another notable patent is a digital signal weighting processing apparatus and method. This invention comprises a sampling section that responds to a measurement start signal, initiating the measurement of an input signal and outputting sample values. It includes a sample value storage section for storing these values in synchronism with each measurement. The apparatus also features a weighting coefficient generation section that calculates weighting coefficients based on the magnitude of the sample values. The weighting section then reads out sample values at the same sampling time point and weights them by the corresponding coefficients to conduct an arithmetical mean operation.
