Publication number: 20230063445Abstract: A rotation base has a base circular structure. A display backing has a backing circular structure. The backing circular structure is rotatably attached to the base circular structure to permit the display backing to rotate between landscape and portrait orientations relative to the rotation base. One of the base and backing circular structures defines a slot. The other of the base and backing circular structures defines a tab rotatably disposed within the slot.Type: ApplicationFiled: February 13, 2020Publication date: March 2, 2023Inventors: Robin P. Yergenson, Brian C. Mayer, Alan Williamson

Publication number: 20230021732Abstract: Examples of the present disclosure are directed toward a control panel display with rotatable mount. An example apparatus includes a control panel mount including a first surface to receive a control panel display and a second surface opposite the first surface. The apparatus further includes a rotatable mount including a first surface and a second surface opposite the first surface. A first hinge mechanism which is rotatable about a first axis may allow the rotatable mount to move between a first operational position in which the rotatable mount is disposed in contiguous contact with a top cover of the apparatus and a second operational position in which the control panel display is disposed within a recessed portion of the top cover. A second hinge mechanism may be rotatable about a second axis orthogonal to the first axis to change a display angle of the control panel display.Type: ApplicationFiled: December 20, 2019Publication date: January 26, 2023Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Josiah RADCLIFFE, Alan WILLIAMSON

Patent number: 8474254Abstract: A system and method for performing a floating function in an earthmoving implement of an earthmoving machine without physically connecting chambers within a hydraulic actuator that is adapted to raise and lower the earthmoving implement. The system includes a device for delivering a pressurized fluid to and receiving pressurized fluid from the actuator, a valve for compensating for differences in volume between chambers of the actuator, and an electronic control circuit that includes electronic sensors for sensing the pressures in the chambers of the actuator, and a controller for receiving outputs of the sensors. The controller calculates an amount of the pressurized fluid that, when delivered to or received from the actuator, achieves a substantially constant pressures in the chambers of the actuator and enables the earthmoving implement to float regardless of motion of the actuator.Type: GrantFiled: November 5, 2009Date of Patent: July 2, 2013Assignee: Purdue Research FoundationInventors: Edward C. Hughes, IV, Christopher Alan Williamson, Joshua D. Zimmerman, Monika Marianne Ivantysynova

Patent number: 8453441Abstract: A system and method for controlling the movement of an implement of an earthmoving machine. The system includes a hydraulic actuator adapted to move the implement. A variable displacement pump is coupled to the actuator for delivering a pressurized fluid to and receiving pressurized fluid from chambers within the actuator. A sensor generates an output based on the position of the actuator's piston or piston rod, and a controller controls the displacement of the variable displacement pump in response to the output of the sensor by executing an algorithm to reduce the flow rate of the fluid to and from the actuator's chambers and thereby reduce the velocity of the piston as it approaches an end of a piston stroke thereof and prevent the piston from impacting the actuator at the end of the piston stroke.Type: GrantFiled: November 5, 2009Date of Patent: June 4, 2013Assignee: Purdue Research FoundationInventors: Christopher Alan Williamson, Monika Marianne Ivantysynova
