Abstract: A method for testing the functionality of an electronic flight bag (EFB) has been developed. First a communication link is established between the EFB and a central maintenance computer (CMC). Next, a power loss presence test is initiated for the EFB. This test determines if critical applications of the EFB are recovered during a restart after a power loss. If the EFB fails the test, a failure message is transmitted to the CMC. Next, a communication bus test is initiated for the EFB. The communication bus test determines if adequate communication links exist between the EFB and a data source for critical applications. If the EFB fails the test, a failure message is transmitted to the CMC.

Abstract: A system and method of protecting one or more objects rendered on a display device from being observed by an unwanted viewer. A primary object is rendered on the display device, and a privacy protection object is simultaneously rendered over at least a portion of the primary object. At least a portion of the privacy protection object is rendered with a color saturation value, a transparency value, and a phase delay relative to the primary object such that the portion of the primary object over which the privacy protection object is rendered is visibly obscured to a viewer that is located greater than a predetermined viewing distance from the display device and beyond a predetermined field of view of the display device.
