  • Patent number: 10876627
    Abstract: Calibration and simulation techniques for modeled gear shift events of an automatic transmission of a vehicle comprise obtaining a set of parameters for a modeled gear shift event of the transmission and, based on the set of parameters, modeling forward/aft vehicle acceleration caused by the modeled gear shift event. A shift quality rating system is the utilized to obtain a shift quality rating of the modeled gear shift event based on at least one of the set of parameters and the modeled forward/aft vehicle acceleration. Finally, the techniques determine whether the determined shift quality rating satisfies a shift quality rating threshold and, when the determined shift quality rating fails to satisfy the shift quality rating threshold, a gear ratio gradient for the modeled gear shift event is adjusted and the process is repeated until the determined shift quality rating satisfies the shift quality rating threshold.

  • Patent number: 6757827
    Abstract: A method and a data file structure (100) for embedding a digital signature verification key (108) within a particular type of image data file enables validation of the image data (102a,b) autonomously—i.e. without consulting large external data bases of public keys or certificates.

  • Patent number: 5675649
    Abstract: A process for cryptographic key generation and safekeeping is provided. A plurality of key agents are selected, each having a copy of the source code. One copy of the source code is loaded onto a secure computer system and is compared with at least one other copy of the source code to validate the loaded copy of the source code. Master key information and locking key information are generated by executing compiled source code. The master key information is then separated into a plurality of master key shares which are distributed to master key agents such that each master key agent possesses one master key share. The locking key information is separated into a plurality of locking key shares which are distributed to locking key agents such that each locking key agent possesses one locking key share. Then, the plurality of locking key shares and the plurality of master key shares are validated, and the secure computer system is securely shut down.
