Latest Patents

Sekimoto's latest inventions include two groundbreaking patents: the "Microbial particle measuring apparatus and microbial particle measuring method," and the "Viable particle counting system and viable particle counting method."

The microbial particle measuring apparatus features a light emitter that irradiates a fluid with a specific wavelength of light over a designated measurement period. It includes a fluorescence receiver that selectively collects fluorescence emitted from particles within the fluid, outputting a signal proportional to the intensity of this fluorescence. A signal acquisition unit captures the signal at regular intervals, while a determiner calculates the slope of the waveform. By analyzing the attenuation of fluorescence intensity during periods of low slope, the apparatus determines the concentration of microbial particles present.

The viable particle counting system consists of a particle counting means and pre-stage irradiation means. This system counts particles in a fluid by irradiating them with light at a predetermined wavelength, effectively distinguishing target particles via their autofluorescence or phosphorescence. The pre-stage irradiation primarily uses ultraviolet light to enhance detection performance, and the system incorporates a band-pass filter to refine the light wavelength range allowed for analysis, ensuring accurate particle identification.
