Abstract: A computerized system for transacting the purchase and sale of consumer motor fuels between motor fuel merchants and retail consumers through software on a mobile or desktop connected device for periods in the future through the simultaneous execution of multi-party, multi-layered contingent transactions and pricing algorithms to ensure that all inter-related motor fuel merchant transactions are simultaneously transacted upon a retail consumer purchase execution. Motor fuels include refined products such as gasoline and diesel fuel, renewable fuels (e.g. ethanol, biodiesel), natural gas (including liquefied natural gas), jet fuel and electricity.

Abstract: An interactive training application has three components: a lesson engine, a lesson delivery system, and a lesson authoring tool. The lesson engine runs an interactive, multimedia training exercise based on the contents of a lesson file, which comprises a plurality of pages. Each page includes a navigation item, associated with another page, and a reference to multimedia content. The lesson delivery system displays a menu of lessons to a student, fetches a lesson file corresponding to the student's selection, and invokes the lesson engine upon the lesson file. The lesson authoring tool provides a graphical interface for inputting and editing storyboards, from which the lesson authoring tool is configured for generating a lesson file.

Abstract: Apparatus is disclosed for selectively dispensing heated water, cooled water, or water at ambient temperature. Water under pressure is supplied to a refrigerated reservoir by a water supply pipe having a solenoid operated valve therein. An ambient dispensing valve and a heated water tank having a dispensing valve are each in communication with said water supply pipe at a location between said valve and reservoir.
