Latest Patents

One of his latest inventions is a fire detector unit. This improved fire detector unit features a plastic base that defines a smoke chamber for detecting smoke density through light scattering caused by smoke particles. The base is equipped with a circuit board that mounts a light-emitting element, a light-receiving element, and other components that form a fire-detecting circuit. This circuit generates a fire warning signal based on the detected smoke density. Additionally, a metal-made electromagnetic shield is molded into the base to protect the light-receiving element from electromagnetic radiation noise. The shield includes a ground terminal for connection with the circuit board's ground line, and terminal pins are molded into the base for electrical and physical connection to the circuit board.

Another significant invention is a particle sensor. This sensor incorporates gain control and offset voltage adjustment to provide a consistent output indicative of particle density, compensating for background noise. The gain control and offset voltage adjustment are achieved through digitally controllable variable resistor networks with multiple switches. A memory module is included to store instruction data for controlling the switches, which is essential for the gain control and offset voltage adjustment. The particle sensor also features a memory interface that allows the selective use of two types of memory means: an intelligent memory module composed of EEPROM and a microcomputer, and a standard memory module consisting of EEPROM.
