摘要： A packet-switched, fault-tolerant, vehicle communication internetwork (100, 400, 500) comprising port-based VLANs. Two or more VLANs are embodied where a source node (110, 410, 510, 610) comprises two or more network interface circuits (130,140, 415,425, 515,525, 630,640), and where looping is precluded via specific VLAN tagging and switch ports (131-134, 200, 300, 420, 430, 435, 445, 455, 465, 535, 540, 545, 560, 575, 585, associated with at least one specific VLAN. A destination node (120, 440, 450, 460, 570, 580, 590, 620) may feedback packets to the source node via a general VLAN tag along pathways associated with the two or more specific outgoing VLAN tags.

摘要： An actuator controller with a power supply that steps down a high voltage for use by remote auxiliary loads in an aircraft is provided. A high voltage power bus running through the aircraft may use high gage or smaller diameter wiring, resulting in weight savings in the power bus. A control network running through the aircraft may use fiber optic cabling, providing further weight reductions. An actuator controller may receive the high voltage from the power bus and provide a lower voltage to a remote device. The actuator controller may facilitate communication between the control network and the remote device. The integration of control and power supply may enhance endurance, reliability, and enable localized calibration of the remote device. Modular wing components may include interface controllers, high and low power busswork, and remote devices. The modular wing components may include power and control interconnections.
