Patent number: 10267020Abstract: In a display system in an excavator, a position of an upper boundary line and a position of a lower boundary line are calculated. The upper boundary line indicates a height of a top of a cross section of a display object surface. The lower boundary line indicates a height of a bottom of the cross section of the display object surface. A predetermined reference point of a display range is set based on a positional relationship in an up-and-down direction between the current position of the excavator and the upper boundary line or between the current position of the excavator and the lower boundary line. A guidance picture showing a cross section of the display object surface included in the predetermined display range as seen from a side of the excavator, and the current position of the excavator, is displayed.Type: GrantFiled: August 15, 2016Date of Patent: April 23, 2019Assignee: KOMATSU LTD.Inventors: Ryo Fukano, Azumi Nomura, Takashi Kurihara, Etsuo Fujita, Masao Ando, Toshihiro Koide

Patent number: 9435106Abstract: In a display system in an excavator, a position of an upper boundary line and a position of a lower boundary line are calculated. The upper boundary line indicates a height of a top of a cross section of a display object surface. The lower boundary line indicates a height of a bottom of the cross section of the display object surface. When the current position of the excavator is between the upper boundary line and the lower boundary line, a predetermined reference point of a display range is set to a predetermined position between the upper and lower boundary lines. When the current position of the excavator is above the upper boundary line, the reference point is set above the predetermined position. When the current position of the excavator is below the lower boundary line, the reference point is set below the predetermined position.Type: GrantFiled: February 8, 2012Date of Patent: September 6, 2016Assignee: KOMATSU LTD.Inventors: Ryo Fukano, Azumi Nomura, Takashi Kurihara, Etsuo Fujita, Masao Ando, Toshihiro Koide

Patent number: 8903604Abstract: A calculation unit of a hydraulic shovel display system sets a predetermined display range displayed as a guidance picture for land shape data. The guidance picture shows a cross section of a target surface included in a display range as seen from a side of a main vehicle body, and a current position of the hydraulic shovel. The calculation unit calculates a position of a start point nearest the main vehicle body and a position of an end point set apart from the start point by a maximum reach length of the work machine in the cross section of the target surface as seen from the side based on land shape data, work machine data and a current position of the main vehicle body. The calculation unit calculates a predetermined reference point of the display range based on the positions of the start point and the end point.Type: GrantFiled: February 8, 2012Date of Patent: December 2, 2014Assignee: Komatsu Ltd.Inventors: Ryo Fukano, Azumi Nomura, Takashi Kurihara, Etsuo Fujita, Masao Ando, Toshihiro Koide

Patent number: 7579811Abstract: It is aimed at stably implementing a protection function of a secondary battery mainly under software control and providing a battery pack characterized by a reduced circuit installation area, parts costs, and power consumption. An AD converter outputs a voltage value between a positive electrode and a negative electrode of a secondary battery. Based on the voltage value, a microcontroller determines a state of the secondary battery out of overcharge, normal operation, and over-discharge states. According to the determined state, the microcontroller controls operations of a discharge current cutoff means and a charge current cutoff means via a FET driver. When it is determined that the secondary battery is placed in an overcurrent state based on the charge and discharge current size of the secondary battery, an overcurrent detection circuit enables the discharge current cutoff means to be a cutoff state in preference to control by the microcontroller.Type: GrantFiled: November 12, 2004Date of Patent: August 25, 2009Assignees: Sony Corporation, Maxim Japan Co., Ltd.Inventors: Hideyuki Sato, Yukio Tsuchiya, Ryuji Nakamichi, Osamu Nagashima, Toshihiro Koide
