Abstract: Envelope tracking can be employed to reduce power consumption of a power amplifier, but envelope tracking can introduce nonlinearities to a power amplifier. These nonlinearities can manifest themselves as noise at the output of the power amplifier. Embodiments described herein provide techniques for characterizing a parameter indicative of power amplifier noise when envelope tracking is employed. Measurement of this parameter can permit power amplifier designers to decide whether to forgo envelope tracking if a power amplifier is too susceptible to such noise, redesign the power amplifier to improve compatibility with envelope tracking, or to employ distortion compensation circuitry to reduce the noise output by the power amplifier. Counterintuitively, this distortion compensation circuitry may involve increasing the power, such as the envelope tracking power supply. However, increasing the power may be a desirable trade-off for increased linearity.

Abstract: A search engine identifies external data records that describe similar entities and may each conform to a different data format or source schema. The engine derives mappings capable of translating data values between differently formatted attributes of two source schemas and uses these mappings to identify degrees of similarity between attributes and schemas. When the search engine receives a search request, the engine translates submitted search criteria into values of a first schema's attributes and then uses the mappings to map those values onto selected attributes of other schemas. The search engine then uses each schema's selected attributes to select external data records formatted in that schema. Each selected record is assigned a match score that is weighted by the similarity of the record schema's selected attributes to the search criteria. Records are then retrieved in order of decreasing match score.

Abstract: The system obtains a set of tickets representing customer requests generated by a customer-support ticketing system. Next, the system feeds words from each ticket through a model to generate a request vector for the ticket, wherein the request vector comprises numerical values representing words in the ticket.

Next, the system identifies clusters of request vectors, which are within a pre-specified distance of each other in the vector space. If an identified cluster is more than a pre-specified distance away from a closest article vector in the vector space, the system notifies a content creator that a new article needs to be written, or an existing article needs to be updated, to cover the identified cluster.
