Publication number: 20230033010Abstract: A first method of protecting an engine and a transmission of a marine vessel during gear shifts and a second method of programming one or more Shift Protection Sequences (SPS) are disclosed. The first method includes receiving a Shift Request (SR) and activating a SPS from among a plurality of enabled SPS. The second method includes configuring a Shift Protection Type (SPT); enabling and configuring a plurality of required and SPS variables; and, optionally, enabling and configuring a plurality of optional SPS variables. The SPT may be a Basic Shift Protection (BSP), which includes time-based SPS; or the SPT may be an Advanced Shift Protection (ASP), which includes alternate time-based and operating-variable based SPS. The SPS of the ASP may be incrementally programmed and added to the BSP.Type: ApplicationFiled: July 27, 2021Publication date: February 2, 2023Applicant: Caterpillar Inc.Inventors: Merritt P. Callaghan, Cameron S. Gandy, Brian P. Neathery

Publication number: 20220380013Abstract: An advanced control station system for a marine vessel. The control station provides a motor-controlled lever head with the ability to control the amount of pressure required to move the lever head as well as the ability to set adjustable detents within the range of motion of the lever head. The advanced control station further provides for electronic communication between multiple stations controls so that the throttle and transmission settings from one control station can be synchronized during a control station transfer.Type: ApplicationFiled: May 28, 2021Publication date: December 1, 2022Applicant: Caterpillar Inc.Inventors: Brian P. Neathery, Cameron S. Gandy, Merritt P. Callaghan

Patent number: 11238833Abstract: A graphical user interface (GUI) of a display screen connected to a machine and, more particularly, to GUIs of one or more display screens that have a relative coordinate system to display parameter information from one or more connected machines. The GUI may include one or more display screens associated with a data bus for a machine, one or more data storage devices for storing processor readable instructions, and at least one processor configured to perform operations stored on the one or more data storage devices. The at least one processor may be configured to receive operations data from the data bus for the machine, extract parameter information from the operations data, and generate the GUI. The GUI may depict a plurality of parameter elements, wherein the plurality of parameter elements are arranged and scaled according to the extracted parameter information, arrangement rules, and display screen resolution.Type: GrantFiled: May 26, 2020Date of Patent: February 1, 2022Assignee: Caterpillar Inc.Inventors: Fu P. Yuet, Meghna Prasad, Keith R. Folken, Merritt P. Callaghan

Patent number: 11040762Abstract: A propulsion system for a marine vessel having a first driveline assembly having a first engine and a first motor-generator, a second driveline assembly having a second engine and second motor-generator, and a controller configured to operate of the assemblies in a split mode. The split mode includes the first driveline assembly being driven by the first engine without torque assistance from the first motor-generator and the second driveline assembly being driven by the second motor-generator without torque assistance from the second engine and includes the first motor generator providing electrical power to the marine vessel grid for consumption.Type: GrantFiled: October 18, 2019Date of Patent: June 22, 2021Assignee: Caterpillar Inc.Inventors: Candace L. Marquis, Merritt P. Callaghan, Adnan Kadribasic, Per Jonas Granath, Brian P. Neathery, Mark I. Harrison

Patent number: 9110467Abstract: The disclosure relates to a marine vessel having a control system for automatically steering the marine vessel for the purpose of aiding an angler who has hooked a fish. The control system includes a GPS unit for determining the orientation of the marine vessel, a sonar unit for determining the bearing of a fish, and an algorithm for minimizing the error between the two. The control system will execute steering commands in the propulsion system in order to minimize the error in order to aid the angler as he tries to land the hooked fish.Type: GrantFiled: September 14, 2012Date of Patent: August 18, 2015Assignee: Caterpillar Inc.Inventors: Fu P. Yuet, Merritt P. Callaghan, Justin Anderson

Patent number: 9067664Abstract: A marine vessel is disclosed having a control system for automatically controlling thrusters for steering the marine vessel for the purpose of aiding an angler who has hooked a fish. The control system will automatically control the thrusters based on the positions of the propulsion unit control levers if the control levers are split. The control system may also control the thrusters if the propulsion unit control levers have moved past a predetermined threshold. The predetermined threshold can be set by the operator of the marine vessel.Type: GrantFiled: May 31, 2013Date of Patent: June 30, 2015Assignee: Caterpillar Inc.Inventors: Fu P. Yuet, Hashim Marzuq, Merritt P. Callaghan, Patrick Lee, Andrew Hutchison
