Publication number: 20240248492Abstract: A system is provided which can achieve reliability of a notification about a moving manner of a work machine for a worker regardless of the distance between the work machine and the worker. A sign image M is projected onto a peripheral region of the worker (for example, a ground surface which is present in the vicinity of the worker to the extent that the worker is capable of visually recognizing the sign image M) by an unmanned aircraft 60. The sign image M is an image which represents a moving manner of a work machine 40. Thus, regardless of the distance between the work machine 40 and the worker, reliability of a notification about the moving manner of the work machine 40 for the worker is achieved compared to a case where the sign image M is projected onto an irrelevant place to the position of the worker.Type: ApplicationFiled: December 13, 2021Publication date: July 25, 2024Inventors: Yuki MORITA, Yusuke FUJIWARA, Kazuhiro UEDA, Yoichiro YAMAZAKI

Patent number: 9590543Abstract: The purpose of the present invention is to reduce noise by controlling vibration due to rotation fluctuation, and to consume only current required for maintaining the rotation by bringing the current for driving a motor closer to a state of synchronization. A drive means drives a sensorless brushless DC motor by switching an energization pattern at a constant frequency to determine the rotation position of the rotor of the sensorless brushless DC motor. A detection means detects a zero-cross signal representing the switching of the phase of the rotor. A calculation means calculates a synchronization determination rate representing a percentage of the number of detected zero-cross signals. A pulse width control means controls the pulse width of a PWM drive duty in the drive means so that the calculated synchronization determination rate falls within a target range.Type: GrantFiled: December 10, 2013Date of Patent: March 7, 2017Assignee: MIKUNI CORPORATIONInventors: Kenichi Watanabe, Naoki Kobayashi, Kazuhiro Fujiwara, Takashi Doi
