Latest Patents

Koji Iio's latest inventions include a DC power-supply unit and a human body detection system. The DC power-supply unit is designed to convert alternating current (AC) into direct current (DC) power effectively. It features a unique mechanism that closes a switch after a preset first delay time when the AC voltage or current passes through a zero point, and opens the switch after a preset second delay time. This innovation includes a rectifier switch, an inductive element, a switching element, and a smoothing unit, which work together seamlessly to control the flow of current.

His human body detection system utilizes a single infrared detector to identify a human presence. This system incorporates a condenser that creates multiple effective detection regions with varying areas. As a human moves across these regions, the infrared detector captures the emitted infrared rays, generating signals that vary in frequency depending on the region. This enables a decision apparatus to discern which part of the detection area is occupied by the human body, enhancing the precision of detection technology.
