Abstract: A method for cardholders to communicate restrictions on card usability in terms of time, amount, number of charges, and merchants to card issuers though dedicated applications on wireless PDA, cell phone, desktop applications, or Web applications, repeatedly and at will, and for card issuers to evaluate future transactions in terms of these restrictions and authorize or decline those transactions based on the results of those evaluations.

Abstract: An automotive type carburetor has a fast idle cam mechanism that provides a dual path of operation that includes one ramp for engagement with the throttle valve stop screw for progressively closing the throttle valve as a function of temperature increases towards the normal operating level, and a second ramp engagable by the stop screw for automatically indexing the stop screw for an automatic return of the fast idle cam to a high cam step position upon a restart of a cold engine without necessitating any action on the part of the vehicle driver other than to render operable the vehicle ignition system.
