Patent number: 11962669Abstract: The present disclosure relates to utilizing a content service system to improve selecting data sources that are used to retrieve digital content items in response to content requests. For example, in response to receiving a content request, the content service system determines to retrieve content items by either calling a lower-quality data source with lower computing costs based on the request having lower service quality metrics or by calling a higher-quality data source with higher computing-costs based on the request having superior service quality metrics. In many instances, the service quality metric is based on the user characteristics of a user identifier associated with the requesting device. By dynamically determining to utilize different data sources having different computing costs based on service quality metrics, the content service system significantly reduces the total amount of computing costs for retrieving and providing digital content, without hurting the user experience.Type: GrantFiled: September 27, 2022Date of Patent: April 16, 2024Assignee: Microsoft Technology Licensing, LLCInventors: José Carlos Almeida Dos Santos, Naseer Ud Din Ahmed Batt, Prateek Tiwari

Patent number: 10969370Abstract: An example method of characterizing a semiconductor sample includes measuring an initial value, Vin, of a surface potential at a region of a surface of the semiconductor sample, biasing the semiconductor sample to have a target surface potential value (V0) of 2V or less, and depositing a monitored amount of corona charge (?Q1) on the region of the surface after adjusting the surface potential to the target value. The method also includes measuring a first value, V1, of the surface potential at the region after depositing the corona charge, determining the first change of surface potential (?V1=V1?V0), and determining the first capacitance value C1=?Q1/?V1, and characterizing the semiconductor sample based on V0, V1, ?V1, ?Q1 and C1.Type: GrantFiled: June 5, 2015Date of Patent: April 6, 2021Assignee: SEMILAB Semiconductor Physics Laboratory Co., Ltd.Inventors: Jacek Lagowski, Marshall Wilson, Alexandre Savtchouk, Carlos Almeida, Csaba Buday

Patent number: 10936945Abstract: Non-limiting examples of the present disclosure describe query classification to identify appropriateness of a query. A query may be received by at least one processing device. A deep neural network (DNN) model may be applied to evaluate the query. A vector representation may be generated for query based on application of the DNN model, where the DNN model is trained to classify queries according to a plurality of categories of appropriateness. The DNN model may be utilized to classify the query in a category of appropriateness based on analysis of the vector representation. In one example, auto-complete suggestions for the query may be filtered based on the classification of the category of appropriateness. In another example, classification of the query may be provided to an entry point. In yet another example, a response to the query is managed based on the classification of the query. Other examples are also described.Type: GrantFiled: June 6, 2016Date of Patent: March 2, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Jose Carlos Almeida Santos, Paul David Arnold, Ward Farquhar Roper, Parth Gupta

Patent number: 10826149Abstract: A dielectric waveguide and/or a cable for transmission of millimeter-wave signals. The dielectric waveguide and/or the cable comprises an inner core having a dielectric medium adapted to transmit a millimeter-wave signal by carrying an electromagnetic field along the dielectric waveguide and/or the cable.
