Abstract: A method for reducing vibrations in an airframe of an aircraft includes determining, with a processor, information indicative of an initial error value between a desired vibration level and a measured vibration level in the airframe; determining, with the processor, an initial adjustment solution for the aircraft in response to the determining of the information for the initial error value; receiving, with the processor, information indicative of a flight response to the initial adjustment solution; combining, with the processor, disturbance signals indicative of vibration noise with the information for the flight response; determining, with the processor, a subsequent error value between the desired vibration level and a subsequent measured vibration level; and determining, with the processor, a predicted adjustment solution in response to the determining of the subsequent error value.

Abstract: A system and a process for emulating a synchronous time-division-multiplexed (TDM) signal across a packet-oriented network by receiving a synchronous TDM signal, such as a SONET signal, at each of a number of processors, also receiving a number of signals from a time-slot decoder, each signal being associated with a respective processor, and processing the received synchronous TDM signal responsive to the received time-slot-decoder signal. Channel processing includes the storing, by at least one of the processors, the received data in a memory element associated with the at least one of the processors, and creating a packet conforming to a protocol of a packet-oriented network, such as internet protocol, MPLS, and asynchronous transfer mode, using the stored data.
