Latest Patents
One of Ishii's latest inventions is a pulse wave analysis device. This device analyzes the condition of a human body by wrapping a cuff band around the tip of the second finger. When the measurement begins, the finger tip is subjected to various pressures using an air pump and pressure sensor. The device automatically measures pulse wave signals at different pressure values through an optical fingertip plethysmogram sensor. These signals are processed by a CPU, which performs FFT analyses to determine the closest pattern from stored data, ultimately displaying the viscoelasticity of the subject's peripheral circulation tissue.
Another significant patent is a fire alarm device designed to detect physical quantities associated with fire outbreaks. This device utilizes preset membership functions to correlate detected physical quantities with the perceived danger level. By calculating the danger degree based on actual fire conditions, the device can provide alarms and control measures that reflect the severity of the situation.
