  • Patent number: 10694324
    Abstract: In some embodiments, a method includes: obtaining position information of a wireless hotspot where the user locates, based on hotspot scanning information of wireless hotspots already scanned by the user; acquiring one or more candidate Points of Interest (POIs) close to the wireless hotspot based on the position information; based on characteristic information corresponding to the wireless hotspot and respective candidate POIs, ranking all candidate POIs to determine an POI matching the wireless hotspot, wherein the characteristic information comprises access characteristic information. In some embodiments, the following advantages may be realized: the POI matching the wireless hotspot is obtained based on relevant data that the user scans the wireless hotspot to predict the POI actually accessed by the user without a procedure of manually collecting the data or user feedback, thereby improving the efficiency.

  • Patent number: 10473475
    Abstract: A method and apparatus are for determining a location of a new point of interest by determining demand information of a user based on retrieval data of the user. The retrieval data includes at least point of interest data, and the demand information includes at least a demand occurrence position. Supply information, including at least a supply region of existing points of interest are obtained based on the retrieval data. The demand information of the user is matched with the supply information of the existing points of interest to obtain the unsatisfied demand information of the user. The location of the new point of interest is determined based on the unsatisfied demand information of the user. The demand information for determining the location of a new point of interest is more accurate and comprehensive, and accuracy and reliability of the site selection of a new point of interest are improved.

  • Publication number: 20190247192
    Abstract: A prosthetic mitral annuloplasty ring includes a wire, an adjustment member for changing a length of the wire and a jacketing annulus for adjusting a radial dimension of the mitral valve annuloplasty ring. The jacketing annulus is sleeved over the wire and forms, together with the adjustment member, a shape matching that of a native mitral valve annulus. After the prosthetic mitral annuloplasty ring is implanted by suturing in a conventional surgical procedure and the patient's heart starts to beat again, the adjustment member can be connected to the delivery device and the wire length therein can be adjusted by a rotating operation of the delivery device so that the mitral valve annuloplasty ring will be expanded or contracted until the prosthetic mitral annuloplasty ring perfectly fits the native mitral valve annulus in shape, effectively avoiding the problem of incomplete mitral leaflet coaptation.
