Abstract: A distributed enhanced payment processing system includes a merchant point of sale (POS) terminal system and a remote payment management system. The POS terminal system initiates a transaction that includes receiving a payment amount, a purchaser account identifier, a virtual electronic payment indicator, and a merchant ID via a payment client. Subsequently, the POS terminal system outputs the transaction to the remote payment management system which generates a token for the transaction. The payment management system then provides the purchaser account identifier, a merchant account identifier, and the payment amount to a remote virtual electronic payment (VEP) entity system. Upon receiving a VEP entity system response, the payment management system outputs the response and token to the POS terminal system.

Abstract: A computer system including circuitry for accurately and economically controlling the charge voltage and charge current at the terminals of its rechargeable battery. During a battery recharge, sensor circuitry coupled to the battery provides accurate data to a battery microcontroller regarding the charge voltage and charge current present at the battery terminals. A battery microcontroller relays this information to a multipurpose microcontroller. The battery microcontroller also provides the desired charging voltage and current as determined by the battery pack's charging algorithm. The multipurpose microcontroller uses the battery status information to program an addressable potentiometer. In turn, the potentiometer generates an adjustment signal that controls the output voltage of the computer's AC adapter. Preferably, the AC adapter is capable of being operated in a constant-power mode.
