  • Patent number: 10467888
    Abstract: A method of dynamically adjusting an emergency coordination simulation system includes performing an emergency coordination simulation for a subarea of a geographic region based on expected user behavior in the subarea and environmental variables of the subarea. An emergency notice is transmitted to a plurality of users. A plurality of citizen sensor reports is received from the users via citizen sensor monitoring devices. The devices communicate with a backend system and form a citizen sensor platform. A consistency check is performed on the plurality of citizen sensor reports. The plurality of citizen sensor reports is filtered to remove outliers. An emergency coordination resimulation is performed for the subarea based on the expected user behavior in the subarea, the environmental variables of the subarea, and the filtered plurality of citizen sensor reports. An updated emergency notice is transmitted to the plurality of users based on the emergency coordination resimulation.

  • Patent number: 10432938
    Abstract: A method and device for coding and decoding are disclosed. The method includes: dividing a picture to be encoded into several slices, each containing macroblocks continuous in a designated scanning sequence in the picture; dividing slices in the picture into one or more slice sets according to attribute information of the slices, each slice set containing one or more slices; and encoding the slices in the slice sets according to slice and slice set division information to get a coded bit stream of the picture. The decoding method includes: obtaining slice and slice set division information from a bit stream to be decoded and decoding the bit stream according to the obtained slice and slice set division information. The invention improves the performance of video transmission effectively and realizes region based coding. The implementation of coding and decoding is simple and the complexity of coding and decoding systems is reduced.

  • Patent number: 10425787
    Abstract: A mobile unit in a housing facility for mobile units may be tracked by activating a first reading device at a first location of the housing facility upon detecting a first mobile unit arriving at or departing from the first location, wherein the first mobile unit has a first tag having an identification code (ID) readable by the first reading device. A set of readings may be performed by the first reading device to read a set of tag IDs during a time interval. Upon an ending of the time interval, tag IDs, in the set of tag IDs, that correspond to the first tag ID are identified based on the set of readings. A record is updated to associate the first tag ID with the first location.

  • Publication number: 20190209075
    Abstract: Social media databases are minded for data related to a subject person. The data in indicative of a level of ultraviolet light exposure of the subject person. An ultraviolet violet exposure profile for the subject person is generated based upon the data and a health assessment report provided. The data may include timestamped images of the subject person and other related persons. The skin characteristics within images are analyzed to determine an ultraviolet light exposure level for the subject person from each image. The skin characteristics may include skin color, freckling and blemishing. The ultraviolet light exposure profile may be developed over an extended interval based upon the image timestamps. The health report may be used to mitigate risks, such as skin cancer, associated with exposure to ultraviolet light.

  • Publication number: 20180276549
    Abstract: A method for reviewing digital publications includes receiving a digital publication while it is being composed. Potential audiences are identified for the digital publication. Information is received from feeds and social media content. A context is modeled for each potential audience based on the received information. The digital publication is analyzed for each potential audience, using the modeled context, by matching content of the digital publication candidate to popular culture references and news information of the corresponding modeled context. Sentiment analysis is performed on the matched content to determine when the digital publication candidate represents a reputational risk to the user for at least one of the potential audiences. A segment of the digital publication candidate corresponding to the matched content is highlighted when it is determined that the reputational risk exists.
