Patent number: 11681320Abstract: In embodiments, a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device, an MRF joystick resistance mechanism, and a controller architecture. The joystick device includes, in turn, a base housing, a joystick movably mounted to the base housing, and a joystick bias mechanism coupled to the joystick and exerting a centering force urging the joystick to return to the centered position when moved therefrom. The controller architecture is operable in a modified centering mode in which the controller architecture: (i) determines when the joystick begins return toward the centered position due to the centering force applied by the joystick bias mechanism; and (ii) when so determining, commands the MRF joystick resistance mechanism to modify a rate at which the joystick returns to the centered position by varying the MRF resistance force applied to the joystick.Type: GrantFiled: May 1, 2020Date of Patent: June 20, 2023Assignee: DEERE & COMPANYInventors: Aaron R.

Patent number: 11667043Abstract: An electromechanical system operates in part through physical interaction with an operator, and includes a multi-axis robot, a controller, and a counterbalance mechanism connected to the robot. The counterbalance mechanism includes a base structure connected to a set of linkages, a pneumatic cylinder, a spring-loaded cam assembly, and an optional constant force spring. The linkages form a four-bar parallelogram assembly connectable to a load. The cylinder and cam assembly, and optional constant force spring, each impart respective vertical forces to the parallelogram assembly. The forces combine to provide gravity compensation and self-centering functions or behaviors to the load, enabling the load to move with a vertical degree of freedom when manually acted upon by the operator, and to return the load to a nominal center position.Type: GrantFiled: February 9, 2021Date of Patent: June 6, 2023Assignee: GM Global Technology Operations LLCInventors: Muhammad E.

Patent number: 11619269Abstract: During installation, an engagement structure of an actuator assembly positioning device restricts movement of a securement element of an anti-rotation bracket past a target location (e.g. midpoint) relative to a securement slot of an thereby, thereby guiding a user in positioning the anti-rotation bracket and actuator in a desired mounting arrangement. An optional constricting structure of the positioning device provides tactile feedback that the desired arrangement of the anti-rotation bracket and actuator has been reached. Upon being subject to a force in excess of a threshold force (e.g., as a result of eccentric loading on the actuator arising from an off-centered mounting of the actuator relative to a rotatable shaft), the engagement structure transitions to a second configuration in which the securement element is allowed to move past the target location, thereby accommodating eccentric movement of the actuator during operation.Type: GrantFiled: October 22, 2019Date of Patent: April 4, 2023Assignee: Johnson Controls Tyco IP Holdings LLPInventor: Russell T.
