  • Patent number: 10706191
    Abstract: Systems, methods, and computer-readable storage media that may be used to generate a Bayesian hierarchical model. One method includes generating a plurality of geographic regions by grouping one or more geographic sub-regions into each of the plurality of geographic regions. The method further includes receiving data for the geographic sub-regions, the data including responses, content inputs, content types, and location identifiers. The method further includes generating geo-level data from the received data by grouping the responses and content inputs of the received data based on a correlation of the location identifiers of the received data to the plurality of geographic regions. The method includes fitting a Bayesian hierarchical model based on at least the geo-level data, the content types, and the geographic regions and determining a content input mix for the content types for each geographic region based on the Bayesian hierarchical model and a content input constraint.

  • Patent number: 9564819
    Abstract: A switching power supply device includes: a transformer; a first switch connected between a high potential terminal of an input DC voltage source and a primary winding; a second switch connected between a low potential terminal of the input DC voltage source and a primary winding; a control circuit outputting a driving pulse signal for synchronizing the first and second switches; first and second rectifying devices; a synchronous rectifier circuit; and a positive bias circuit that applies a positive bias to a control terminal of one of the first and second switches so as to constantly turn the one of the first and second switches ON. When the first and second switches stop a switching operation while an output voltage exists between the output terminals, the positive bias circuit applies the positive bias to the one of the first and second switches.

  • Patent number: 9490717
    Abstract: A switching power supply device includes: a main transformer; a main switch that is connected between a high potential terminal of an input direct current voltage source and a primary-side main winding; a synchronous rectifier circuit includes: a rectifying switch that is connected to a secondary-side main winding in series and that is turned ON in synchronization with a turning ON state of the main switch and a commutation switch that is connected to the rectifying switch series circuit in parallel and that is turned ON in synchronization with a turning OFF state of the main switch; and an auxiliary switch circuit that turns the commutation switch OFF. When the main switch stops a switching operation while a voltage exists at a first output terminal on a high potential side, the auxiliary switch circuit turns the commutation switch OFF to prevent continuation of self-excited oscillation.

  • Patent number: 9270166
    Abstract: A power factor improvement circuit is configured with two series circuits each having a switching element and a rectifying element connected in series. Two input terminals of a single-phase AC power source are respectively connected between the switching elements and the rectifying elements in the series circuits. An inductor element is connected between an output terminal of the power factor improvement circuit and two terminals, which are on the other side of the rectifying elements, of the switching elements. A capacitor element is connected between the output terminal and the two terminals. According to the above configuration, it is possible to decrease a loss of a bridge circuit and common-mode noise, and to provide a power factor improvement circuit in a smaller size.
