Abstract: An iron core-annular array multi-ring magnetosensitive current sensor and a current measurement method, the method comprising: using a first loop structure (101) to acquire a feedback current signal generated according to a first magnetic field signal generated by a primary side current; using a second loop structure (102) to measure a second magnetic field signal generated by the current of a wire in a coil; and using a digital processing unit (103) to calculate, according to the feedback current signal and the second magnetic field signal, the feature quantity that characterizes the current of the wire, and determining the current on the wire according to the feature quantity that characterizes the current of the wire.

Abstract: The present disclosure provides a flight anti-collision method and apparatus based on electromagnetic field detection of an overhead transmission line. An example method includes: determining whether an overhead transmission line around is an Alternating Current (AC) transmission line or a (Direct Current) DC transmission line; if the overhead transmission line is an AC transmission line, determining a position relationship between an aircraft and the overhead transmission line on the basis of a phase distribution model and an electric field phase and a magnetic field phase measured by a phase detector on the aircraft; if the overhead transmission line around is a DC transmission line, determining the position relationship between the aircraft and the overhead transmission line on the basis of a magnetic field intensity distribution model and the magnetic field intensities collected by magnetic field intensity sensors on the aircraft; and thus controlling the aircraft.

Abstract: Provided here are methods, systems, and apparatus, including computer programs encoded on computer storage media, for searching new media information using search engine. One of the methods includes: receiving search information input by a user using a search engine, and sending the search information to a server; obtaining, from a search result returned by the server, element data of new media information related to the search information; and displaying, in a current search result page of the search engine, the element data of the new media information in a new media display format, wherein the element data is data that is directly displayable without a page jump in response to an operation of the user on the element data.
