Abstract: An aircraft airflow sensor includes one or more pitot inlets, ports, and/or static ports and a calibration data memory physically storing calibration data with the aircraft airflow sensor probe. The aircraft airflow sensor moreover includes where the calibration data is configured to be implemented in an air data computer (ADC).

Abstract: Exemplary multimeter-wave acoustic resonators and methods employing intermediate layers in the fabricating of piezoelectric devices based on thin-film lithium niobate/lithium tantalate or aluminum nitride/scandium aluminum nitride on a substrate in a film stack that can use higher order first and third antisymmetric bulk acoustic tones. In some embodiments, the acoustic resonator comprises a base substrate of a material with low electromagnetic loss, a piezoelectric film layer that is suspended over the base substrate, and an interdigitated electrode (IDE) array formed by a pair of independently addressable microelectrode arrays disposed on a top surface of the piezoelectric film layer to resonantly vibrate at a range of frequencies greater than 6 GHz. The piezoelectric film layer was formed over an intermediate or sacrificial layer positioned between the base substrate and the piezoelectric film layer and then etched to provide the piezoelectric film layer suspended over the base substrate.

Abstract: An apparatus for coupling and sealing tubes, comprising a flexible duct having a first and second end portions, each portion having an outwardly extending seal portion connected to a flat portion, which in turn is connected to an angled portion which connects to a flat portion having expanded diameter. The apparatus also comprises a sealing assembly comprising a split ring, a compression ring and an end cap subassembly which fits over the compression and split rings. The end cap subassembly comprises a pair of half-rings which are hinged together at one end and latched together using a closure mechanism at the other end. The split ring is mounted over the duct end seal after a tube with a bead is inserted inside the duct. A compression ring is fit over the split ring and the end cap subassembly is latched in place over the compression and split rings, thereby placing the duct seal portion under compressive pressure against the tube and maintaining it in place in a sealed relationship.
