Patent number: 10871412Abstract: An apparatus for measuring pressure is disclosed. The apparatus can be used to measure static pressures or dynamic pressures as would a conventional microphone, but can be integrated with antenna elements, and can be implemented without need for conductive elements in the array itself to provide the sensed pressure signal for processing. Instead, diaphragm movement is remotely and wirelessly sensed and used to determine pressure.Type: GrantFiled: November 27, 2018Date of Patent: December 22, 2020Assignee: THE BOEING COMPANYInventor: John E.
