  • Patent number: 10109085
    Abstract: A data perspective analysis method is provided. The method includes obtaining, using a processor, one or more perspective criteria stored in a memory device. The method includes gathering, at the processor, master data and transactional data associated with each of the one or more perspective criteria.

  • Publication number: 20170249669
    Abstract: A system receives registrations of users specifying a geographic preference and product preferences for demonstrations. The system likewise receives notifications of available demonstrations from vendors. Relevant demonstrations are identified for each user. In response to detecting a demonstration meeting the user's geographic preference, a notification of the demonstration is transmitted to the user. Notifications may be sent in response to demonstrations within a threshold distance from a location specified by the user, upon the user entering a store near a scheduled time for a relevant demonstration. Notifications may be sent in response to detecting a relevant demonstration within a threshold time from a predicted shopping trip of the user.

  • Patent number: 9138711
    Abstract: A population of nanoparticles is disclosed. The population is comprised of a plurality of core/shell nanocrystals, each including: a semiconductor core, an intermediate semiconductor shell layer disposed over the semiconductor core, an external semiconductor shell layer disposed over the intermediate semiconductor shell layer, and a hydrophilic organic layer in direct contact with the external semi-conductor shell layer.
