Abstract: This invention of a continuous motion revolving piston engine describes a machine comprising piston(s) fitted to rings that revolve around a stator circular base which has a cavity in which a disc fits to create a closed combustion compartment together with the casing. The disc has a disc cavity to allow the piston to pass. The rotation of the disc and piston are synchronized to allow the piston to pass through the disc cavity. As there are no reciprocating parts and optionally enables an oil free operation, it is more efficient and has cleaner exhaust than existing engines.

Abstract: This invention of a revenue management willingness to pay higher fares indicator, provides a method to define in a computer based revenue management system, levels of willingness to pay higher fares, used to improve the forecasting of potential revenue and improve the availability controls defined by the revenue management system. Where current revenue management systems use booked fare class information as basis for forecasting revenue, when demand with a higher willingness to pay higher fares books in a low fare class, this information is not recognized as only the (lower) booked fare class information is stored and used. The method proposed defines levels of willingness to pay higher fares based on booking record characteristics without directly using the actual booked fare class and storing this information for usage in further steps in forecasting and defining availability controls by the revenue management system.
