Abstract

Embodiments of the invention include devices, systems and methods for operating a pressure wave detector. Embodiments include attaching a plurality of members and a ground plate to a substrate, and coupling the ground plate with the plurality of members attached to the substrate. Embodiments also include measuring a pressure wave by at least one of the plurality of members, converting the pressure wave into an electrical signal representing the pressure wave, and monitoring the pressure wave over a configurable period of time.

First claim

What is claimed is:

1. A method of detecting a pressure wave, comprising:
attaching a plurality of members and a ground cylinder to a substrate;
coupling the ground cylinder with the plurality of members attached to the substrate;
measuring a pressure wave with at least one of the plurality of members;

measuring the pressure wave with the plurality of members;
converting each of the plurality of measurements of the pressure wave into an electrical signal representing the pressure wave;
monitoring the pressure wave over a configurable period of time; and
determining a direction of a source of the pressure wave based at least in part on the plurality of measurements by the plurality of members.

2. The method of claim 1 , wherein a distance between the plurality of members and the ground cylinder alters a capacitance indicating an amount of pressure of the pressure wave.

3. The method of claim 1 , further comprising determining a magnitude of the pressure wave based at least in part on the plurality of measurements by at least one of the plurality of members.

4. The method of claim 1 , wherein a plurality of pressure wave sensor systems are located on a nose, tail, and wings of an aircraft.

a ground cylinder coupled to the substrate;
a plurality of members coupled to the substrate, wherein the plurality of members operate as pressure sensing cantilevers, wherein the plurality of members are used to determine a plurality of measurements and a direction of a source of the pressure wave based at least in part on the plurality measurements by the plurality of members;
one or more ports; and
one or more lines coupled to the ground cylinder, the plurality of members and one or more ports on the substrate, wherein one or more ports are coupled to a system for controlling a pressure sensitive electronic unit based at least in part on a detected pressure wave.

14. The device of claim 13 , wherein a distance between the plurality of members and the ground cylinder alters a capacitance indicating an amount of pressure of a measured pressure wave.

15. The device of claim 13 , wherein the plurality of members determines a magnitude of the pressure wave based at least in part on a measurement by at least one of the plurality of members.
