Patents by Inventor Stephanie L. Roberts

Stephanie L. Roberts has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Control system and method for cycle-based processes
    Patent number: 6242877
    Abstract: An apparatus for controlling operation of a processing machine has a computer preferably with a computer aided design program configurable to model a kinematic velocity profile of a point of interest on a machine to be controlled. A graphical user interface on the computer enables an operator to select desired velocity points for a motor drive controlling motion of the point on the machine. A curve fit is applied to the velocity points to realize a desired velocity profile for the motor drive and the point on the machine. The desired velocity profile is then integrated and scaled in order to obtain a scaled velocity profile that realizes an actual, or target displacement of the point as dictated by operation of the machine. By controlling operation of elements of a machine with velocity profiles, coordination of associated elements and points on the machine can be visualized by an operator selecting the velocity points for each drive of the machine. A method for implementing same is also disclosed.
