  • Patent number: 10555226
    Abstract: A method and an apparatus for determining a location of a mobile device. The location of a mobile device is determined accurately according to information which includes call data records of the mobile device. By employing a partial ellipse integral model, two physical world factors are taken into consideration in reducing the location uncertainty in call data records. The factors include: spatiotemporal constraints of the device's movement in the physical world and the telecommunication cell area's geometry information, which increase the accuracy of determining the location of a mobile device.

  • Patent number: 10536749
    Abstract: Media-presentation-conscious scheduling protocols are disclosed that may associate a geographical location containing a thing with an identifier of the thing and allow later-found media works that pertain to the identifier to be presented at a mobile device before the device reaches a waypoint of the location. Alternatively or additionally, such protocols may respond to a predicted connectivity impairment of a traveling device by obtaining supplemental content to mitigate a predicted capacity shortage. Alternatively or additionally, such protocols may interrupt live stream content, insert on-demand content, and later return to live stream presentation automatically.

  • Publication number: 20190314117
    Abstract: Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems of the invention include tooth attachments having improved or optimized parameters selected or modified for more optimal and/or effective application of forces for a desired/selected orthodontic movement. Attachments of the present invention can be customized to a particular patient (e.g., patient-customized), a particular movement, and/or a sub-group or sub-set of patients, and configured to engage an orthodontic tooth positioning appliance worn by a patient, where engagement between the attachment and orthodontic appliance results in application of a repositioning force or series/system of forces to the tooth having the attachment and will generally elicit a tooth movement.

  • Patent number: 10423943
    Abstract: Provided herein are systems and methods for generating a set of recommended media works based on an identified seed media work. The seed media work is used to identify a set of co-occurring media works, which are defined as media works that have been intentionally interacted with within a predetermined time window as the seed media work by a single user. After the co-occurrence set is created, it is ranked and filtered. Media works identified in the co-occurrence set may then be selected based on their ranking.
