Abstract: An electronic device, and an operation method thereof, are disclosed. The electronic device may include a memory; and a processor configured to execute at least one operating system executed in a first region allowing an operation based on a first authority; execute at least one application executed in a second region allowing an operation based on a second authority; receive a first authority policy from a server; obtain a second authority policy from the at least one application; and in response to detection of access to at least one device resource by the at least one application, configure authority of access to the at least one device resource, according to a third authority policy based on the first authority policy and the second authority policy, by using an authority determination module executed in a third region allowing an operation based on a third authority.

Abstract: A system and method for authentication. In some embodiments, the method includes displaying a plurality of objects to a user's left eye and to the user's right eye, and monitoring the user's eye positions while the user looks at a subset of the displayed objects, one at a time. The method may further include comparing an angular offset for an object of the plurality of objects to a vergence measured for the user's eyes while the user looks at the object.

Abstract: A wake turbulence warning and caution system and method for a protected aircraft tracks and stores a trajectory of a wake trailing behind a nearby aircraft and adjusts the wake position for the effect of local wind velocity, and then calculates a distance and time to closure between the protected aircraft and the wake. A caution is annunciated aurally and/or on a navigation map display and/or on a primary flight display if the distance or time to closure is less than a first predetermined threshold, and a warning is annunciated if the distance or time to closure is less than a second predetermined threshold. The wake trajectory is calculated based on range, bearing, and altitude information about the nearby aircraft supplied by a Traffic Collision Avoidance System (TCAS) aboard the protected aircraft, and based on inertial position and attitude of the protected aircraft supplied by an inertial reference system (IRS).
