Debt management system
InactiveUS20050097033A1Low costEfficient actionFinanceSpecial data processing applicationsCredit cardCost effectiveness
A debt management system includes a financial planning tool that examines a user's mortgages, home equity loans, auto loans, savings, credit cards, and unsecured debt to determine actions that can be taken to improve the user's debt situation. Upon receiving and saving user financial information, the debt management system dynamically recommends the most cost-effective debt management actions available to the user. The recommendations are based upon one or more parameters, such as desired debt management strategy, optimized user-selected financial goals, user credit information, available debt reduction instruments, real time interest rates, and current underwriting guidelines and upon a variety of user-inputted information. The recommendations of the debt management system are monitored and adaptively changed according to changes in the fiscal environment.

ActiveUS20120014148A1Total current dropImprove efficiencyEfficient power electronics conversionDc-dc conversionHigher order harmonicsSwitching frequency
Light load efficiency of a power factor correction circuit is improved by adaptive on-time control and providing for selection between a continuous conduction mode and a discontinuous conduction mode wherein the discontinuous conduction mode increases time between switching pulses controlling connection of a cyclically varying voltage to a filter / inductor that delivers a desired DC voltage and thus can greatly reduce the switching frequency at light loads where switching frequency related losses dominate efficiency. The mode for controlling switching is preferably selected for each switching pulse within a half cycle of the cyclically varying input voltage. A multi-phase embodiment allows cancellation of EMI noise at harmonics of the switching frequency and adaptive change of phase angle allows for cancellation of dominant higher order harmonics as switching frequency is reduced.
