  • Patent number: 6963782
    Abstract: The present invention includes a system and method for fine tuning the control of a manufacturing process. A material adjusting device is in communication with a PID controller and PID control loop, and is used to alter a flow of material used in the manufacturing process, so as to maintain a target physical property of the material at a setpoint. A measurement device captures measurements of the flow relevant to the physical property of interest. A change is introduced to the material adjusting device while the PID controller and PID control loop are disabled, and appropriate measurements of the flow are continually captured; a process that may be repeated several times. Once sufficient physical property measurement data has been captured, the data is loaded into an optimization program that outputs optimized controlled parameters that may be used by the PID controller and control loop to better control the physical property of the material.

  • Patent number: 6728594
    Abstract: The present invention includes a central control system and method for fine tuning a cigarette manufacturing process. A measurement device captures measurements of particular cigarette properties. The measurement data is sent to and stored in a central database. Once sufficient measurement data has been stored, the data is loaded into an optimization program that outputs optimized controlled parameters that may be used by individual control systems to better control the properties of the cigarettes during manufacture. The central control system and method may be used with both off-line and in-line measurement devices, and can communicate and control such devices regardless of the manufacturer thereof.

  • Patent number: 6675073
    Abstract: The present invention includes a system and method for fine tuning the process of controlling the weight of a flow of material, such as a rod of material in a production facility. A control actuator in communication with a PID controller and PID control loop is used to change the unit volume of the flow so as to maintain a target unit weight. A measurement device captures unit weight measurements of the flow at intervals over the length of the flow. A change is introduced to a control actuator while the PID controller and PID control loop are disabled, and appropriate weight measurements of the flow are continually captured along with the control actuator's “feed back” position; a process that may be repeated several times. Once sufficient weight measurement data has been captured, the data is loaded into an optimization program that outputs optimized controlled parameters that may be used by the PID controller and control loop to better control the weight of the flow of material.
