Abstract: A device comprises a first comparator to generate a first clock signal based on a reference voltage and a first voltage at an output of a switched-capacitor power converter (SCPC), and a second comparator to generate a first control signal based on the first voltage and a threshold voltage. A sensor is to generate a second control signal based on one of a level of a current of the first clock signal, or a duty cycle of the first clock signal. A frequency divider circuit is to generate a second clock signal based on the first control signal and the second control signal, and in some embodiments, further based on one of the first clock signal or a third clock signal. Controller circuitry is to operate switch circuitry of the SCPC based on the first clock signal.

Abstract: A method for content categorization including firstly retrieving content from a first content source from among a categorized list of content sources, extracting a plurality of words from the firstly retrieved content, associating any of the words with a category to which the firstly retrieved content is associated in the categorized list, secondly retrieving content from a second content source independently from the categorized list of content sources, extracting a plurality of words from the secondly retrieved content, and associating the secondly retrieved content with the category where any of the words in the secondly retrieved content matches any of the words in the firstly retrieved content, where the match is in accordance with a predefined heuristic.
