  • Machine learning item delivery using sensor data
    Patent number: 11941572
    Abstract: Various embodiments are disclosed for providing machine learning routines with peripheral device data to infer driver activity and location. Peripheral device data may be collected on a peripheral device having a machine learning routine executing thereon to infer driver activity and perform improved estimation of driver location. Using driver activity and location estimation, contextually relevant delivery workflow assistance may be automatically provided to a delivery driver or other individual without requiring manual input, thereby improving driver safety and operational efficiency.

  • Multiple prime number generation using a parallel prime number search algorithm
    Patent number: 7120248
    Abstract: A process is provided for searching in parallel for a plurality of prime number values simultaneously includes the steps of: randomly generating a plurality of k random odd numbers (wherein k is preferably more than 2, but could also be one or more) expressed as n0,0, n1,0, . . . n((k?1)),0, each number providing a prime number candidate; determining a plurality of y additional odd numbers based on each one of the randomly generated odd numbers n0,0, n1,0, . . .
