Abstract:
An aircraft in-flight entertainment system includes a plurality of seat electronic units (SEUs) that are daisy chained through a packet data network (PDN) loop to a content server containing media content. The SEU includes a power supply, a communication switch, a processor, a communication interface, and a power control circuit. The power supply supplies power to the communication switch, the processor, and the communication interface. The communication switch selectively routes packets containing media content through the processor and the communication interface to the video display unit, or through a segment of the PDN loop to a downstream electronic unit. The power control circuit responds to the power supply supplying less than a threshold level of power by supplying power to the communication switch from the segment of the PDN loop connected to the upstream electronic unit and/or the downstream electronic unit.
Abstract:
An object recognition computer for a vehicle includes at least one processor and at least one memory storing program code executable by the at least one processor to perform operations. The operations are configured to receive video streams from a plurality of cameras spaced apart within the vehicle and each having a field-of-view capturing at least one passenger seat. For each of the video streams, the operations retrieve from a data structure information that defines a region within video frames of the video stream where object recognition is to be performed to attempt to identify a defined object associated with the at least one passenger seat. The operations then perform object recognition limited to within the defined region to identify the defined object. Notifications can be selectively generated to passengers and/or crew based on the object recognition.
