  • Bitcell wordline strapping circuitry
    Patent number: 10923161
    Abstract: Various implementations described herein are directed to an integrated circuit. The integrated circuit may include a bitcell and multiple straps including a first strap, a second strap, and a third strap. The first strap may couple the bitcell to ground. The second strap may couple the bitcell to a bitline. The third strap may couple the bitcell to a wordline within a boundary of the bitcell.
    Type: Grant

  • Using an artificial neural network for combustion phasing control in a spark ignited internal combustion engine
    Patent number: 10788396
    Abstract: A calibration system and method for a spark ignition engine of a vehicle involve artificially weighting engine dynamometer data in high engine load regions and using it to generate training data for an artificial neutral network (ANN). A plurality of ANNs are trained using the training data and the plurality of ANNs are then filtered based on their maximum error to obtain a filtered set of trained ANNs. A statistical analysis is performed on each of the filtered set of trained ANNs including determining a set of statistical metrics for each of the filtered set of trained ANNs and then one of the filtered set of trained ANNs having a best combination of error at high engine loads and the set of statistical error metrics is then selected. Finally, an ANN calibration is generated using the selected one of the filtered set of trained ANNs.
