  • Patent number: 10839245
    Abstract: A structured document analyzer that associates keys and values in structured documents based on key, value, and key-value container bounding boxes. A trained machine learning model analyzes images of structured documents to determine bounding boxes for keys, values, and key-value containers in the images with confidence scores for the classifications. For each image, duplicate bounding boxes are removed, and then a set of key-value containers are selected and sorted based on the confidence scores. For each key-value container, a best key and value are determined for the container based on overlap of the key and value bounding boxes with the container bounding box and the confidence scores. Optical character recognition may be performed on the image to determine text for the keys and values.

  • Patent number: 10819213
    Abstract: A method for detecting zero-current of a voltage converter includes resetting a comparator output during a first period when a power switch of the voltage converter is turned on, and receiving, by an offset cancellation circuit, sample signals from the comparator. The method also determines a comparator offset using the sample signals. In response to an output voltage of the voltage converter being less than a threshold voltage, the comparator output is reset during a second period when the power switch is turned off. The comparator compares a first signal from the voltage converter with a second signal representing a ground voltage to generate a ZCD signal indicative of a comparison of the first and second signals. Then, an offset cancellation signal indicative of the determined comparator offset is generated to cancel the comparator offset.
