Title: Hideo Takahashi: Innovator in Optical Measurement Technology
Introduction
Hideo Takahashi is a prominent inventor based in Hamamatsu, Japan. He has made significant contributions to the field of optical measurement technology, holding a total of 3 patents. His work focuses on developing innovative devices that enhance the accuracy and reliability of biological measurements.
Latest Patents
Takahashi's latest patents include a noninvasive biological optical measuring instrument, a measured portion holding device, and a method for manufacturing the same. The noninvasive biological optical measuring instrument is designed with a measurement site holder constructed using a negative impression of the measurement site. This design reduces variations in measured values caused by the non-uniform distribution of components in the measurement site. It also minimizes the impact of variations in light path length and blood flow that can occur due to differences in contact pressure. Additionally, living-body information and measurement parameters are recorded on a dedicated recording medium, preventing erroneous acquisition of data for individual patients and allowing for reproducible measurements.
Another notable patent involves a photodetector and solid-state imaging apparatus. This device features a light chopper that periodically transmits and blocks light. A dark current cancelling circuit determines an approximate mean value of the dark current from a photodiode when the light is blocked. This mean value is then canceled from the current signal fed into the integrated circuit. Furthermore, a differential arithmetic circuit subtracts the remaining dark current component from the output of the integration circuit, ensuring that the remaining signal reflects only the signal current component.
