A method and an apparatus for controlling an interrupt in a portable terminal are provided. One embodiment provides a method for managing access to sensitive data in a database. Redundancy information corresponding to each segment also is distributed randomly over the storage units. In a further embodiment, two endoscopes are associated with the probe. The rotating electrical machine consists of an alternator or a starter-alternator or an alterno-starter comprising such an assembly. This method allows the functionality of a newly designed CPU to be checked in a simulation, even before actual system integration.
