Abstract: A higher-order acoustical pressure measurement device (e.g., microphone) is disclosed. The device includes a first acoustic pressure measurement from a generally concentrated spatial location and a second acoustic pressure measurement having a spatiality greater than the concentrated spatial location of the first acoustic pressure measurement and at least one destructive interference signal. The destructive interference signal is characterized at least in part by the spatiality of the second acoustic pressure measurement. A higher-order microphone includes sensor elements configured to provide a destructive interference signal such that interference at one sensor element is configured to lower the destructive interference signal for the primary direction of directivity from a source signal.

Abstract: A business method to expand upon prior art methods of billing a utility customer's energy consumption from local power generation energy sources such as wind and solar systems. The invention discerns energy generated locally and energy consumed from a wide area energy source, utility or COOP. The invention allows power generated locally by leased, owned, or rented power generation equipment at the utility customer's location to be measured and billed to the customer at a separate rate than that charged by the utility to the customer. A well-engineered system will locally generate enough power to offset the utility's charges, lower the power customer's power costs and will provide revenue to the local power generation equipment provider by a power billing presented to the utility customer. The invention may utilize any power generation method such as electric, gas, oil, biomass, and or thermal.
