Patent number: 11914599Abstract: Apparatus and associated methods relate to mitigating data-stream dropout in a serial data-stream. A time-sequence of messages of the serial data-stream is received, each containing a data packet communicating an action. Validity of each of the time-sequence of messages received is determined. After receiving each valid message, a plurality of future actions is created based at least in part on the valid message received. The plurality of future actions corresponds to a plurality of future data packets of the time-sequence of messages. After receiving each valid message, the action communicated in the valid message received is performed. After receiving each invalid messages, a next one of the set of sequential future actions created is instead used in place of any action communicated in the data packet of the invalid message received.Type: GrantFiled: November 19, 2021Date of Patent: February 27, 2024Assignee: Hamilton Sundstrand CorporationInventors: Kirk A. Lillestolen, Kanwalpreet Reen, Richard A. Poisson
