Abstract: Described herein is a sensor probe for association with a portion of an aircraft. The sensor probe includes a microphone assembly having a portion configured to receive audio signals. The sensor probe further includes a nosecone associated with the microphone assembly. The nosecone assembly is configured to shield the portion of the microphone assembly from noise generated by direct impact of an airflow for a plurality of local flow angles. In some examples, the nosecone includes a tip and a body portion, wherein a diameter of the body portion of the nosecone is smaller than a length of the nosecone and the nosecone is configured to mitigate drag of the sensor probe in an airflow.

Abstract: Described herein is an aircraft. The aircraft includes a peripheral assembly, such as a sensor probe. The aircraft further includes a release assembly connecting the peripheral assembly to a portion of the aircraft. The release assembly is configured to separate the peripheral assembly and the portion upon receipt of a threshold force. The release assembly may be configured to allow for the quick release, such as via a snap-fit connection, between the peripheral assembly and the portion of the aircraft.

Abstract: An acoustic detection system of an aircraft receives a first signal, where the first signal is a multichannel audio signal. The multichannel audio signal is determined to be associated with at least one intruding aircraft based on the multichannel audio signal. An avoidance maneuver is commanded for the aircraft based on a track of the intruding aircraft generated based on the multichannel audio signal and a second signal providing additional information about the intruding aircraft.

Abstract: A rules-based accounting system and method for accounting for transactions, comprises a transaction engine for receiving transaction events, an accounting engine for determining a set of rules to apply to the transaction event, deriving accounting information for the transaction based on the set of rules, and posting the derived accounting information to the account. The transaction events are processed as they are received and reconstruction is performed where the transactions are not received in proper order. The set of rules to be applied to the transaction event are determined by a cost basis, transaction classification, asset classification and event type. Rules may added, changed or removed by the user as needed.
