  • Patent number: 10728702
    Abstract: Techniques are disclosed for networked data management using pedestrian traffic patterns. Data is collected from a plurality of mobile devices by one or more immobile devices. A traffic pattern is determined for a subset of the plurality of mobile devices. Interest level management and cluster analysis can be performed using the traffic pattern. Pausing by a mobile device, within the subset of the plurality of mobile devices, can be sensed. Direction of a gaze by an individual associated with the mobile device can be evaluated. A plurality of content messages is ranked, and one message is selected from the plurality of content messages as the content for pushing to the display. The content that is pushed can be defined using environmental information. Content is pushed to a display associated with the one or more immobile devices.
    Type: Grant
    Filed: January 19, 2018
    Date of Patent: July 28, 2020
    Assignee: Changing Environments, Inc.

  • Patent number: 8575394
    Abstract: A process for the preparation of an 1,1-disubstituted oxirane is disclosed, wherein an organic sulphide is reacted in a polar solvent with an educt containing a leaving group attached to a primary or secondary carbon atom, and/or the sulfonium salt formed in this way is reacted with a ketone in presence of a base and a polar solvent. Oxiranes of the type obtained may be further converted into the corresponding ?-hydroxyketone or ?-aminoketone, either in one step by subjecting to aerobic oxidation in the presence of a transition metal catalyst, or in two steps by hydrolyzation in the presence of an aqueous acid to the corresponding dialcohol and subsequent selective oxidation. Further described are some novel epoxide intermediates. The ?-hydroxyketones and ?-aminoketones thus obtainable are useful inter alia as photoinitiators.
