Latest Patents

Hiroshi Kiyosugi holds a patent for a magnetic brake system and elevator trouble detection system. This invention aims to accurately detect issues with a magnetic brake by eliminating the effects of temperature at the installation site. The system incorporates a temperature sensor to measure the magnetic brake's temperature. When the armature is attracted in response to a brake release command, the temperature is recorded as the first temperature. Before the armature returns in response to a brake actuation command, the temperature is measured again as the second temperature. A comparison of these temperatures allows for the determination of whether the magnetic brake has developed a trouble, specifically if the difference exceeds a predetermined value.
