Patent number: 11939741Abstract: A work vehicle comprising a frame supported by a ground engaging device. A boom assembly is coupled to the frame. An attachment coupler is coupled to the boom assembly. An electronic data processor is communicatively coupled to a boom actuator, an attachment coupler actuator, a boom sensor, an attachment coupler sensor, and an operator input device. A computer readable storage medium comprising machine readable instructions that, when executed by the processor, cause the processor to receive an operator input and for a tilt forward command, command the boom actuator to move the boom assembly to a frame contact position and then command the attachment coupler actuator to move the attachment coupler towards a lower position. For a tilt rearward command, command the attachment coupler actuator to move the attachment coupler towards an upper position and then command the boom actuator to move the boom assembly towards a raised position.Type: GrantFiled: October 28, 2019Date of Patent: March 26, 2024Assignee: Deere & CompanyInventors: Alex R.

Patent number: 10893947Abstract: A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.Type: GrantFiled: September 5, 2018Date of Patent: January 19, 2021Assignee: Zimmer, Inc.Inventors: Jeff Blaylock, Michael Cook, Ron Donkers, Scott Dykema, Maleata Hall, John E.

Patent number: 9814583Abstract: The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough.

Patent number: 8888857Abstract: A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available. The meniscal component includes a mechanism for preventing lift off of the meniscal component from the tibial component, while allowing rotation of the meniscal component relative to the tibial component.Type: GrantFiled: September 5, 2012Date of Patent: November 18, 2014Assignee: Zimmer, Inc.Inventors: John E.
