Abstract: Approaches presented herein enable obscuring a query from an external web service provider. More specifically, a user-submitted query is split into at least two non-identical, secondary search queries. The non-identical search queries are submitted to an external web services provider separately, at different times spread throughout a search timeframe, from different virtual locations, thereby obscuring the original search query from the external web services provider. An internal system receives and merges the search results of the non-identical secondary queries from the external web services provider. The internal system then performs a second search on the merged results using the original user-submitted search query to find the results within the merged results that are most relevant to the original query. These relevant results are then presented to the user.

Abstract: A voltage converter whose output voltage is determined by the duty cycle of at least one switch and which includes ripple steering circuitry, and a current source whose output current is determined by the duty cycle of at least one switch and which includes ripple steering circuitry. In some embodiments, the voltage converter includes at least one yoked switch pair, circuitry for controlling the duty cycle of the yoked switch pair, and ripple steering circuitry. Preferably, the voltage converter includes a transformer, an input side, an output side, and ripple steering circuitry implemented on the input side. Examples of voltage converters in the first class are forward converters, flyback converters, and full bridge forward converters.

Abstract: An improvement is provided for a circuit having a first winding of N.sub.1 turns connected in series with a total inductance of L across a first voltage V.sub.1 and a second steering winding of N.sub.2 turns connected in series with a total inductance L.sub.2 across a second voltage V.sub.2 with the second winding magnetically coupled to the first winding and the first winding having an inductance L.sub.c produced by the N.sub.1 turns as seen across the first winding comprising L.sub.1 set substantially greater to zero and L.sub.2 set substantially equal to (L.sub.c) (N.sub.2 /N.sub.1).sup.2 ((V.sub.2 /V.sub.1) (N.sub.1 /N.sub.2)-1)). The setting of L.sub.1 and the setting of L.sub.2 providing an improvement to reduce ac ripple current.
