  • Patent number: 11099816
    Abstract: A workflow development system is described that provides a developer with a search utility for finding steps for inclusion in a workflow. The system also automatically generates a meaningful name and/or graphical representation for a workflow. The system also provides a graphical user interface that represents output parameters of a first workflow step as user-interactive objects. These objects can be interacted with to cause the objects to be inserted into a data entry element that is used to specify a value for an input parameter of a second workflow step. When executable logic representing the first and second workflow steps is generated, the insertion of the objects into the data entry element has the effect of causing the value of the input parameter of the second workflow step to be defined to include the values of the output parameters that correspond to the inserted objects.

  • Patent number: 11031262
    Abstract: Implementations disclosed herein describe a bevel etch apparatus within a loadlock bevel etch chamber and methods of using the same. The bevel etch apparatus has a mask assembly within the loadlock bevel etch chamber. During an etch process, the mask assembly delivers a gas flow to control bevel etch without the use of a shadow frame. As such, the edge exclusion at the bevel edge can be reduced, thus increasing product yield.

  • Publication number: 20210156327
    Abstract: A method of calibrating a soot load estimating function for a diesel particulate filter uses radio frequency attenuation measurement and temperature measurements. The method comprises identifying a minimum mean attenuation value associated with a standard deviation that exceeds a standard deviation threshold and using this minimum mean attenuation value as a reference value. The method further comprises using a data library that contains gradient values for each of a range of possible temperature values to obtain a first gradient value, the first gradient value corresponding to the first temperature value, wherein each gradient value relates to the gradient of a linear approximation between mean attenuation and soot load at the corresponding temperature. The method involves using the reference value and the first gradient value to determine an axis intercept value for use as an offset value and adopting the offset value as a temperature-independent calibration value for the diesel particulate filter.
