  • Publication number: 20240140029
    Abstract: The present application relates to an apparatus and method for three-dimensional printing. The apparatus comprises a gantry, a tilting print head and a rotary table. The tilting print head comprises an extruder, an elongated nozzle connected to the extruder and a filament tube connected to side-entrance of the extruder. The extruder is configured to rotate around the tilting axis. The filament tube is configured to feed the printing material into the extruder. The tilting print head is configured to control the printing material to enter the extruder through the filament tube, spiral through the extruder and enter the elongated nozzle. As the entrance is arranged on the side of the extruder and the filament tube is close to the tilting axis, the printing material can be more stable when the tilting print head rotates upward or downward.

  • Patent number: 11972803
    Abstract: A memory device that uses different programming parameters base on the word line(s) to be programmed is described. The programming parameter PROGSRC_PCH provides a pre-charge voltage to physical word lines. In some instances, the PROGSRC_PCH voltage is decoupled, and a new PROGSRC_PCH represents an adjusted (e.g., increased) pre-charge voltage for a certain physical word line or word line zone (i.e., predetermined group of word lines). Using different PROGSRC_PCH voltages can limit or prevent Vt distribution window degradation, particularly for relatively low physical word lines. Additionally, the overall programming time and average current consumed can also be reduced.

An MPC module includes a robot dynamics model which inherently reflects response nonlinearities associated with changes in robot configuration, and an optimization solver having an objective function with a torque rate term and inequality constraints defining bounds on both torque and torque rate. The torque rate control in the MPC module provides an effective means of controlling jerk in robot joints, while accurately modeling robot dynamics as the robot changes configuration during a motion program. End tooling oscillation dynamics may also be included in the MPC objective function and constraints in order to automatically control end tooling vibration in the calculations of the MPC module.
