  • Publication number: 20210011466
    Abstract: A real-time control system includes a simulation system to implement a predictive, look-ahead function that provides an operator with information that enables a higher level of situational awareness of the expected transitional events of future steps within the control program or sequence logic. The simulation system enables future steps and transitions to be monitored before they actually occur, which enables the operator to recognize and potentially take action, in a current time step, to alleviate the underlying cause of the problem, thus reducing the likelihood of or preventing a sequence stall of the control program.

  • Patent number: 10877294
    Abstract: Contact lenses incorporating an array of non-coaxial lenslets with add power that create non-coaxial myopic defocus within the optic zone of the lens may be utilized to prevent and/or slow myopia progression. The positive, non-coaxial lenslets cover about twenty to eighty percent of the central pupil area to deliver positive foci of light in front of the retina to slow the rate of myopia progression.

  • Publication number: 20200328304
    Abstract: A method for improving breakdown voltage of a Laterally Diffused Metal Oxide Semiconductor (LDMOS) includes biasing a first well of a Field Effect Transistor (FET) to a first voltage. The first well is laterally separated from a second well. An isolation ring is charged to a second voltage in response to the first voltage exceeding a breakdown voltage of a diode connected between the isolation ring and the first well. The isolation ring laterally surrounds the FET and contacts a buried layer (BL) extending below the first well and the second well. A substrate is biased to a third voltage being less than or equal to the first voltage. The substrate laterally extends below the BL and contacts the BL.

  • Patent number: 10606254
    Abstract: Systems and approaches for error detection detect discrepancies in industrial equipment by comparing a particular asset to similar industrial assets running in parallel to the particular asset. An error detection unit detects a difference between an estimated and actual output of the asset. Based on the magnitude of the difference, the error detection unit determines whether an input value of the particular asset is similar to input values of the plurality of industrial assets and whether an output value of the particular asset is similar to output values of the plurality of industrial assets. If the input value of the particular asset is similar to the input values of the plurality of industrial assets and the output value of the particular asset is not similar to the output values of the plurality of industrial assets, then the error detection system sets an alarm.
