Publication number: 20240068494Abstract: The present invention provides a controller for hydraulic apparatus (100). The controller is configured to determine (310) that an energy return criteria has been met by movement of a first movement component of a first hydraulic actuator. In response thereto, the controller is further configured to select (320) at least one among a plurality of energy control strategies based on at least one operational characteristic of the hydraulic apparatus, and to control (330) the hydraulic apparatus to implement the energy control strategy during movement of the first movable component in such a way as to meet the energy return criteria. The plurality of energy control strategies comprises a first energy control strategy and a second energy control strategy. The at least one operational characteristic of the hydraulic apparatus comprises an indication of an expected energy recovery of one or more of the energy control strategies.Type: ApplicationFiled: December 30, 2021Publication date: February 29, 2024Inventors: Alexis DOLE, Matthew GREEN, John HUTCHESON, Daniel ABRAHAMS, Niall CALDWELL

Patent number: 11884518Abstract: A pipelayer machine includes a propulsion system, a ranging, and a controller in communication with the propulsion system and the ranging system. The controller is configured to receive a predetermined distance that the pipelayer machine is to maintain between the pipelayer machine and an adjacent pipelayer machine, determine, via the ranging system, a first distance between the pipelayer machine and the adjacent pipelayer machine, and determine that a difference between the first distance and the predetermined distance is outside of a predetermined tolerance range. The controller is further configured to modify a speed of the propulsion system based at least in part on determining that the difference is outside of the predetermined tolerance range, wherein modifying the speed of the propulsion system causes acceleration or deceleration of the pipelayer machine.Type: GrantFiled: January 31, 2020Date of Patent: January 30, 2024Assignee: Caterpillar Inc.Inventors: Curtis John Caldwell, Aaron J.

Publication number: 20230419792Abstract: A system and method involving the use of poker bots to play poker games. In one version, poker tournaments are separated into a first “pre-bubble” stage and a second “in-the-money” stage. The pre-bubble stage lasts until each of the remaining players is eligible to win an award (e.g., if the tournament has 100 players, the pre-bubble stage may last until 10 players remain). The in-the-money stage continues from the end of the pre-bubble stage until the conclusion of the poker tournament. During the pre-bubble stage, poker bots control all play. During the in-the-money stage, players may use their bots or override their bots on a hand-by-hand basis.Type: ApplicationFiled: June 23, 2023Publication date: December 28, 2023Inventors: Robert Williams, John Caldwell

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
