  • Patent number: 9936025
    Abstract: Described herein is a framework for vehicle-to-vehicle communication. In accordance with one aspect, a send message to a receiving driver of a receiving vehicle is generated from a sending end-user device in response to a user event from a sending driver. The send message may be generated to include an image of the receiving vehicle of the receiving driver, and a voice message created by the sending driver. The send message may be sent to a server using the sending end-user device. The send message may further be processed by the server, in which the processing may include identifying the receiving vehicle, searching to find information of a receiving end-user device, and sending the send message to the receiving end-user device if information of the receiving end-user device is found.

  • Publication number: 20150269642
    Abstract: Described herein is a framework for an integrated shopping assistance. In accordance with one aspect, the framework may detect a customer in an establishment. The framework may detect the customer by determining location proximity data of one or more detected customer-registered devices in an establishment. The framework may further perform, based on one or more data sources, image recognition of a captured image of a customer. Information associated to the customer may be retrieved from the one or more data sources. Real-time analytics may further be performed based at least in part on the location proximity data and the retrieved customer information. The framework may present, via a client device, a notification based on the location proximity data, a verification of the customer, the associated customer information, and results of the analytics.
