The method uses onboard navigation aid systems, such as a flight management system, a system for managing in-flight alerts for the implementation of the following steps: creation of a task by the flight management system; scheduling of the tasks by a system for managing alerts; and task execution by the system for managing alerts. | 06-30-2011 |
| 20110153873 | METHOD AND DEVICE FOR DETECTING ERRONEOUS TRANSFERS FOR MICROCONTROLLER OR MICROPROCESSOR WITH A VIEW TO GUARANTEEING PARTITIONING - A method and a device for the detection of erroneous or inopportune transactions of any entity of a microprocessor or microcontroller includes programming counters internal or external to the microcontroller, which is configured to count the number of transactions in the target area of the target interface of the microcontroller; count the total number of transactions on the target interface, and verify that the number of transactions outside of the target area of the target interface of the microcontroller is zero. Equality between the number of transactions in the target area of the target interface and the total number of transactions on the target interface of the microcontroller is verified. | 06-23-2011 |
