Abstract: Vehicle power distribution systems are described comprising one or more advanced master control units in electrical communication with a vehicle power source. The advanced master control unit is configured to receive the vehicle current and generate a first current in response to the vehicle current. Power outlets and/or data ports may be in electrical communication with the advanced master control unit, such that they can receive the first current. The system may also have a simple power supply that can receive the first current and convert this to a second current, which can be used to power in-flight entertainment devices and other components of the vehicle.

Abstract: Enhanced short circuit damage protection by using circuit card and electronic assembly features to steer liquids, including water, onto detector arrays. In a typical implementation, a circuit card has detection elements in one or more places implemented as artwork on an outer circuit layer. The finished circuit card assembly is conformal coated with masked areas over detection artwork. When the masking is removed, channels are left behind for liquids to flow toward and pool over detection artwork. In other implementations through shaping, additive or subtractive manufacturing processes, cavities are left behind for liquids to collect over detection artwork.
