Patent number: 11821172Abstract: A controller may obtain, from one or more first devices of a first machine, first information regarding a load associated with a first portion of an object. The first portion, of the object, may be carried by an implement of the first machine and a second portion, of the object, may be carried by an implement of a second machine. The controller may obtain, from one or more second devices of the first machine, second information regarding an orientation of the first machine. The controller may determine, based on the first information and a threshold derived based on the second information, that a load drop condition is satisfied; perform a first action associated with dropping the load; and transmit, to the second machine, information regarding the first action to cause the second machine to perform a second action.Type: GrantFiled: October 8, 2020Date of Patent: November 21, 2023Assignee: Caterpillar Inc.Inventors: Daniel W. Hoyt, Curtis John Caldwell, Aaron J. Gnagey

Patent number: 11704942Abstract: A system may comprise a device. The device may be configured to receive, from one or more sensor devices of the machine, sensor data associated with wear of one or more components of an undercarriage of the machine; and predict, using a machine learning model and the sensor data, an amount wear of the one or more components based on a wear rate of the one or more components. The machine learning model is trained, using training data, to predict the wear rate of the one or more components. The training data includes two or more of: historical sensor data, historical inspection data, or simulation data, of a simulation model, from one or more third devices. The device may perform an action based on the amount of wear.Type: GrantFiled: October 29, 2020Date of Patent: July 18, 2023Assignee: Caterpillar Inc.Inventors: Li Zhang, Eric J.
