Publication number: 20160001701Abstract: A site-aware controller and various sensors determine if objects are located within a safety dome surrounding a machine such as a construction vehicle. The site-aware controller compares data from the various sensors to determine if the machine or independently moveable implements located on the machine are capable of impacting objects within the safety dome and/or travel of the machine into restricted areas. Detection of objects within the safety dome can trigger alerts (e.g., visual and/or audible) to an operator of the machine of a particular situation. Detection of objects within the safety dome can also prevent further movement of the machine or independently moveable implements located on the machine to prevent impacting the objects. The system can also prevent movement of the machine into restricted areas.Type: ApplicationFiled: July 1, 2015Publication date: January 7, 2016Applicants: TOPCON POSITIONING SYSTEMS, INC., INFOMOBILITY S.R.L., TIERRA S.P.A.Inventors: Daniele Pagliani, Nicola Finardi, Aldo Longhi, Ivan Di Federico

Publication number: 20150308074Abstract: On a dozer, a semi-automatic system automatically translates a joystick to control blade elevation and provides an indicator display to guide manual control of blade slope angle. A mechanical linkage operably couples the joystick to an electrical motor. A computational system receives measurements from measurement units mounted on the dozer; calculates estimated values of elevation and slope angle; compares the estimated values to reference values; and calculates error and control signals. Drivers generate a motor drive signal and a display drive signal. In response to the motor drive signal, the electrical motor translates the joystick to control elevation. In response to the display drive signal, the indicator display generates a graphical representation of the status of slope angle. When the operator needs to take manual control, a proximity sensor detects the presence of at least a portion of the operator's hand, wrist, or forearm and disengages automatic control of elevation.Type: ApplicationFiled: April 24, 2014Publication date: October 29, 2015Applicant: Topcon Positioning Systems, Inc.Inventors: Alexey Vladislavovich Zhdanov, Stanislav Georgievich Saul, Alexey Andreevich Kosarev, Ivan Giovanni di Federico, Anton Gennadievich Golovanov

Patent number: 9115999Abstract: A digital video camera is placed on a vehicle. The video camera is attached to the vehicle and is directed to a surface at a certain angle to the surface. The camera angle can change while vehicle is in motion. The camera angle is constantly measured by angular sensor (i.e., inclinometer). Images of the surface are projected onto a video matrix and transformed into a sequence of digital frames that are formed at a pre-set time interval. A speed of the video camera relative to the surface is calculated as a ratio of an off-set between the adjacent frames and the time interval between the frames. Then a known relative speed of the vehicle can be corrected by multiplication of the height of the camera (above the surface) by a coefficient that equals a ratio of the known vehicle speed and the measured camera speed.Type: GrantFiled: September 4, 2012Date of Patent: August 25, 2015Assignee: Topcon Positioning Systems, Inc.Inventor: Michael Y.
