  • Patent number: 10770983
    Abstract: An isolated switched-mode power converter converts power from an input source into power for an output load. A digital controller senses a secondary-side voltage, such as a rectified voltage, of the power converter. The secondary-side voltage is divided down using a high-impedance voltage divider. The resultant divided-down voltage is provided to a voltage sensor within the digital controller. The voltage sensor level shifts the provided voltage, and buffers the resulting level-shifted voltage. The buffered, level-shifted voltage is provided to a tracking analog-to-digital converter (ADC) for digitization. The buffered signal provided to the tracking ADC has a high current capability, such that the voltage input to the tracking ADC may quickly converge before the tracking ADC outputs a digital value for the sensed secondary-side voltage.

  • Patent number: 10454879
    Abstract: A method and system for processing Domain Name Services (DNS) request in a gateway. The gateway receives a DNS request from a host from its local area network. The gateway then selects DNS server(s) and transmits a new DNS request to at least one DNS server(s). DNS server(s) may or may not be accessible through a first tunnel. The contents of the new DNS request are the same as the content of the received DNS request. Further, when the gateway receives a DNS response corresponding to the DNS request, it determines a decision whether to transfer data to the host whose IP address is specified in the DNS response through a second tunnel. The decision may be based on a geographical location of an IP address.
