Latest Patents
Kunihiko Maejima holds a patent for a gas detector comprising plural gas sensors and a gas detection method. This gas detector includes metal-oxide semiconductor gas sensors and their driving circuit. The device is designed to store the ratio of initial gas sensor resistance in air and that in an atmosphere containing Freon gas. It learns the sensor resistance in air for a gas sensor in use and detects Freon gas by comparing the sensor resistance of the gas sensor in use with the learned resistance in air divided by the ratio. After a predetermined period of use, both the first gas sensor and a second gas sensor are utilized for a learning period to continue detection of Freon by the first gas sensor and to learn the resistance in air of the second gas sensor. Upon completion of the learning period, Freon is detected by the second gas sensor.
