  • Publication number: 20170109615
    Abstract: Computer-implemented methods and systems for automatically classifying businesses from imagery can include providing one or more images of a location entity as input to a statistical model that can be applied to each image. A plurality of classification labels for the location entity in the one or more images can be generated and provided as an output of the statistical model. The plurality of classification labels can be generated by selecting from an ontology that identifies predetermined relationships between location entities and categories associated with corresponding classification labels at multiple levels of granularity. Confidence scores for the plurality of classification labels can be generated to indicate a likelihood level that each generated classification label is accurate for its corresponding location entity. Associations based on the classification labels generated for each image can be stored in a database and used to help retrieve relevant business information requested by a user.

  • Patent number: 9628120
    Abstract: A system includes a crest-factor reduction circuit, a signal analyzer, and a pre-distortion circuit. The crest-factor reduction circuit reduces a crest factor of a baseband signal and generates a feedforward signal. The signal analyzer generates parameters based on the feedforward signal and an output signal from a power amplifier. The pre-distortion circuit generates a pre-distorted baseband signal based on the parameters for input to the power amplifier.

  • Patent number: 9319058
    Abstract: Methods and apparatus for blind detection and correction of interleaving errors using all-digital processing of data output by multiple sub-ADCs of a time-interleaved ADC are disclosed. The methods and apparatus detect and correct frequency-dependent timing and gain mismatches of the sub-ADCs of the time-interleaved ADC using a novel multiple-input multiple-output (MIMO) filter structure. Additionally, a novel adaptive sampling frequency hopping scheme is proposed to achieve uninterrupted data conversion by the time-interleaved ADC during transient time of ADC clock frequency switching.
