Patent number: 11880527Abstract: A device to enable touchless operation of an instrument is disclosed. The device includes an actuator configured to vibrate the instrument, a controller configured to control the actuator, and an interval detector configured to detect an interval between the instrument and an object to operate the instrument. The controller is configured to start vibrating the actuator having been still after the interval detected by the interval detector reaches a first threshold, keep vibrating the actuator until the interval detected by the interval detector reaches a second threshold larger than the first threshold after the interval reaches the first threshold, and stop vibrating the actuator after the interval detected by the interval detector reaches the second threshold.Type: GrantFiled: December 8, 2022Date of Patent: January 23, 2024Assignee: SHANGHAI TIANMA MICRO-ELECTRONICS CO., LTD.Inventors: Hiroshi Haga, Koji Shigemura, Hirotsugu Yamamoto
