  • Patent number: 11447175
    Abstract: A method for a steer by wire steering system. The method includes determining a difference between a commanded steering ratio and an achieved steering ratio and determining whether the difference between the commanded steering ratio and the achieved steering ratio is greater than a threshold. The method also includes, in response to a determination that the difference between the commanded steering ratio and the achieved steering ratio is greater than the threshold, adjusting the commanded steering ratio to be equal to the achieved steering ratio. The method also includes, in response to a determination that the difference between the commanded steering ratio and the achieved steering ratio is greater than the threshold, selectively adjusting a bandwidth of a filter based on at least one vehicle characteristic of an associated vehicle and adjusting, using the filter, the commanded steering ratio to be equal to a desired steering ratio.

  • Patent number: 11384343
    Abstract: The present invention relates to non-naturally occurring polypeptides useful for preparing armodafinil, polynucleotides encoding the polypeptides, and methods of using the polypeptides. The non-naturally occurring polypeptides of the present invention are effective in carrying out biocatalytic conversion of the (i) 2-(benzhydrylsulfinyl)acetamide to (?)-2-[(R)-(diphenylmethyl)sulfinyl]acetamide (armodafinil), or (ii) benzhydryl-thioacetic acid to (R)-2-(benzhydrylsulfinyl)acetic acid, which is a pivotal intermediate in the synthesis of armodafinil, in enantiomeric excess.

  • Publication number: 20220169307
    Abstract: A method for diagnosing an input power supply providing power to a motor includes: applying, using the input power supply, a power stimulus to the motor; measuring a response to the power stimulus; calculating, based on the response to the power stimulus, a metric indicative of a status of the input power supply; determining a degraded condition of the input power supply based on the metric indicative of the status of the input power supply; and performing an action in response to determining a degraded condition of the input power supply. The action may include one or more of: limiting an output power supplied to the motor; generating a diagnostic trouble code; and/or notifying an operator of the degraded condition of the input power supply.
