Abstract: A novel oscillator comprises a curved sheet structure. The curved sheet structure comprises a curved sheet and a tensioner. The curved sheet structure oscillates when the tensioner of the curved sheet structure is extended between two rigidly or semi rigidly fixed points and the curved sheet structure is exposed to a fluid flow. The oscillation results in oscillating tension in the tensioner and oscillating motion of the tensioner in directions perpendicular and parallel to the direction of fluid flow. Energy conversion devices to couple the energy out of the oscillator include a coupling in line with the tensioner and a coupling generally perpendicular to the extension of the tensioner.

Abstract: A computer system implementing a macro economic model based upon macroeconomic data and relative value characteristics data of patents that determines nominal values for (1) goods and services and (2) profits generated by sales that are covered by the rights of a patent, implements an income value theory to value the patent based upon the predicted values of profits or goods and services covered by the patent, determines patent terms from patent filing, publication, and issue dates, determines patent assignees from patent data, and uses the value of a company's patents, the patent issuance data and term date data, to determine trends versus time in: the number of a company's enforceable patents; the number of a company's patents obtained; the nominal value of net earnings and of goods and services sold that are covered by the company's patents; the nominal value of the sum of the company's patents, and provides comparisons of those trends between companies, regions, and economic sectors, providing the results
