Publication number: 20190312426Abstract: An interface control circuit includes an interface signal transceiver circuit and a protection circuit. The interface signal transceiver circuit transmits and/or receives an interface signal through a transmission interface which includes at least a first interface pin. The protection circuit includes a switch and a comparison circuit. The switch controls a conduction between the first interface pin and a signal source. The comparison circuit senses a voltage of the first interface pin, and determines whether the voltage of the first interface pin is within a threshold voltage range which corresponds to a foreign object attachment event, whereby the interface signal transceiver circuit is triggered to execute a protection operation.Type: ApplicationFiled: January 14, 2019Publication date: October 10, 2019Inventors: Chih-Wei Mu, Chieh-Min Lo, Wei-Chung Chang

Patent number: 9773045Abstract: Search results may include both objective results and person results. In one example, a search query is evaluated to determine whether it is the type of query that a user might want to ask to a friend. If the query is of such a type, then the search engine may examine a social graph to determine which friends of the user who entered the query may have information that is relevant to answering the query. If such friends exist, then the friends may be displayed along with objective search results, along with an explanation of each friend's relevance to the query. Clicking on a person in the results may cause a conversation to be initiated with that person, thereby allowing the user who entered the query to ask his or her friend about the subject of the query.Type: GrantFiled: September 17, 2013Date of Patent: September 26, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Sandy Wong, Wei Mu, Jun Yin, Rahul Nair, Simon King, Srinivasan Badrinarayanan, Xavier Legros, Michael Ching, Kevin Haas, Shubha Nabar
