Patent number: 11964569Abstract: In a case of a normal operation, a battery controller (22) assumes a normal operation mode and permits charging and discharging of a battery module (21). Upon receiving a discharge command from a vehicle body controller (17) for completely discharging the battery module (21), the battery controller (22) assumes a discharge mode to discharge the battery module (21) to reach a safe voltage level and store discharge information. Upon reading out the discharge information, the battery controller (22) assumes a discharge prohibition mode to prohibit charging and discharging of the battery module (21).Type: GrantFiled: July 4, 2019Date of Patent: April 23, 2024Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Toshihiko Watanabe, Seiji Ishida, Ken Takeuchi

Patent number: 11497382Abstract: A system and method for displaying an endoscope image in a preferred orientation. An endoscope scans a sample with spectrally encoded light by rotating imaging optics inside an endoscope guide. A processor generates an image based on light returned from the sample, and rotates the image by a first angle offset value and a second angle offset value to display the rotated image in the preferred orientation. The first offset value is an angle difference between a specific direction in which the image is to be displayed on a display and a direction in which the tip of the endoscope is oriented with respect to the imaging plane. The second offset value is an angle difference between a direction of the line of scanning light projected onto a plane perpendicular to the tip and the specific direction in which the image is to be displayed.Type: GrantFiled: March 26, 2021Date of Patent: November 15, 2022Assignee: Canon U.S.A., Inc.Inventors: Mitsuhiro Ikuta, Anderson Thi Mach, Seiji Takeuchi, Xuri Yan
