Abstract: A system receives information for a plurality of invoices having invoice amounts owed by a debtor-buyer to a plurality of creditor-suppliers, a cash pool amount for a cash pool available by the debtor-buyer for early payment of at least some of the invoice amounts, and a desired return rate, receives a plurality of offers, each offer from a corresponding creditor-supplier and comprising an offer return rate, determines whether each of the plurality of offers is eligible for acceptance based on each offer return rate from each offer and the desired return rate for the buyer and selects one or more invoices each having an invoice amount, and transmits award information to the debtor-buyer.

Abstract: A DC/DC voltage multiplier comprises a charging source (Vs) connected between first and second terminals (Vdd and Vss), a storage capacitor (Ctr) connected between the first terminal and a third terminal (Vdd and Vtr), a plurality of voltage pump stages each comprising four switches (S1a, S1b and S1c) and a pump capacitor (C1). The switches are actuated under the control of a clock (not shown) so that the pump capacitors of the stages are charged one at a time. The multiplied voltage output between the first and third terminals Vdd and Vtr of the circuit is provided by the charging source (Vs) and the pump capacitors in those stages not currently being charged (C2,C3). Any number of voltage pump stages can be used provided that the output of each stage is connected to the input of the following stage and the circuit is driven by an appropriate clock. The output of the final stage is connected to the input of the first stage so as to form a ring of pump stages.
