Abstract: Controlling machine pose using sensor fusion includes receiving from each of a plurality of Inertial Measurement Units mounted on different components, a time series of signals indicative of acceleration and angular rate of motion for each of the components of the machine, and from at least one non-IMU sensor, a signal indicative of at least one of position, velocity, or acceleration of at least one of the components, a position, velocity, or acceleration of any potential obstacles or other features, or an operator input. The signals are fused with a separate Kalman filter module to estimate an output joint angle. Estimated and measured values of the output joint angle in successive timesteps are combined, a kinematic equation is solved to determine a real time value for at least one of position, velocity, and acceleration of the component at successive timesteps, and the determined real time value is applied in an implementation of a controlled operational movement of the machine component in a successive time step.

Abstract: A combination of seals and wear guides for use in a hydraulic cylinder provides a sealed engagement between a piston rod of the hydraulic cylinder and an inner circumferential surface of a rod end of a cylinder barrel of the hydraulic cylinder through which the piston rod is axially movable. The combination includes a cylindrical metallic wear guide for seating within a first annular groove formed around the inner circumferential surface, a buffer seal assembly including an annular buffer seal cooperatively mated with an annular backup ring for seating within a second annular groove, a U-cup seal for seating within a third annular groove, a cylindrical plastic wear guide for seating within a fourth annular groove, and a triple lip wiper seal including three ringed lip portions for seating within a fifth annular groove.

Abstract: A hydraulic pump or motor includes a mounting flange that is disposed at the first end of the housing. The mounting flange defines a pair of bolt receiving slots that are disposed along the X-axis on either side of the shaft. The pair of bolt receiving slots each define a radius center that are spaced away from each other a X dimension, and a pilot projection extends longitudinally away from the mounting flange, defining a pilot projection diameter. A ratio of the X dimension to the pilot projection diameter ranges from 1.1 to 1.5.

Abstract: A hydraulic pump or motor includes a mounting flange that is disposed at the first end of the housing. The mounting flange defines a pair of fastener receiving apertures that are disposed along the X-axis on either side of the shaft. The pair of fastener receiving apertures each define a radius center that are spaced away from each other a X dimension, and a pilot projection extends longitudinally away from the mounting flange, defining a pilot projection diameter. A ratio of the X dimension to the pilot projection diameter ranges from 1.07 to 1.11.

Abstract: A female mounting member is configured to mate with a hydraulic pump or fan. The member includes a body that defines a projection receiving cavity defining a cavity diameter, and a first threaded hole defining a first threaded hole diameter. A ratio of the cavity diameter to the first threaded hole diameter ranges from 8.0 to 8.15.
