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: Improved clasp structure for use with both planar-type and curvilinear button-type external electrode sensors for electrical transfer of ECG signals. An integral connector on this universal-type clasp structure provides mechanically interlocked connection with a shielded cable to significantly reduce signal interference from external electrical sources. This new clasp structure can be used and reused in a sterile environment; it can be sterilized in a steam autoclave and is partially covered with sterilized surgical tubing so as to prevent pick-up of stray patient signals.
