Latest Patents

Shinohara's latest patents include innovative designs for power window apparatuses with advanced functions. One of his patents describes a power window apparatus with a function of pinching detection. In this invention, a microcontroller unit (MCU) monitors changes in motor rotating speed from the motor start to detect a peak in the motor's speed. It measures the time taken from the motor start to the point where the decrease in speed is maximal, establishing an activation/cancellation time period. This period is adjusted by adding a predetermined time to account for door vibration.

Another patent focuses on a power window apparatus with a pinch detecting function. Here, the MCU determines if there is backlash in the driving system, which includes a motor and window driving mechanism. If backlash is detected, the MCU sets a termination time for the start cancellation period based on the time elapsed since the peak of the motor's rotations. If no backlash is present, the termination time is set based on the rate of change of the motor's revolutions.
