Abstract: An electronic circuit comprises an error amplifier and an overshoot and undershoot detection circuit. The error amplifier has an output stage including a differential input to single ended output amplifier that includes a frequency compensation resistor. A switch circuit is connected across the frequency compensation resistor that shunts the frequency compensation resistor when activated. The overshoot and undershoot detection circuit compares differential input nodes of the output amplifier to a baseline voltage signal and activates the switch circuit when detecting an overshoot condition or an undershoot condition using the baseline voltage signal.

Abstract: A method and apparatus for providing distributed fleet communications between aircraft including decentralized location tracking, weather data, and fleet health is used to determine actual aircraft position, better weather data from multiple sources, and health data to help with logistical calculations and increase efficiencies. The communication is a distributed communication network using blockchains wherein the block includes a data, a hash and a prior hash, determining, by a processor, a validity of the block in response to a blockchain register stored on a memory, the hash and the prior hash, determining, by the processor. The processor is configured to generate a record to be added to the local copy of the blockchain ledger stored in the memory, then send an update to the fleet blockchain to be added as a valid record to be stored and used by the fleet or other trusted individual operators.

Abstract: A communication node for use in a distributed communication network, a communication network and a method for monitoring communication and cybersecurity in a distributed communication network are provided. The communication node includes, but is not limited to a communication module, a memory, and a processor. The communication module is configured to communicate with a communication module of another communication node in a distributed communication network and to store a local copy of a blockchain ledger in the memory. The processor is further configured to generate a record to be added to the local copy of the blockchain ledger stored in the memory every time the communication node communicates with any of the plurality of communication nodes in the distributed communication network. The processor is further configured to verify and monitor the permissioned blockchain by consensus computing and previous hash comparisons.

Abstract: A system and a method for drone detection and collision avoidance, particularly for use in an aircraft, is provided. The system includes, but is not limited to a sensor, a processor, and an avoidance unit comprising a control unit.
