Abstract: Sensor data having values received from several sensors of a mobile device and response data associated with the sensor data may be used in the determination or training of a predictive model. Received sensor data may be input into the predictive model, and the output of the predictive model may be used in the selection and serving of content items to the mobile device. Data to effect presentation of the selected content item may be outputted to the mobile device to effect presentation. In some instances, the predictive model may be updated using the received plurality of values. The updated predictive model may be used in the selection of a subsequent content item for the mobile device. In other implementations, historical sensor data may be used with the set of received sensor data as input for the predictive model.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. A first call for content to be published on a resource associated with a publisher is received from a requesting device. A determination is made when the publisher has authorized additional content item calls to be automatically generated responsive to receipt of the first call. A first content item responsive to the first call is determined. A message including call parameters is generated that define publisher or serving system criteria for the additional content items. The first content item and message responsive to the first call are provided. A second call for content, in conformance with the call parameters, is received after processing the message. A second different content item that is responsive to the second call is provided for publication on the resource along with the first content item.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. Login credentials provided by a user are received when communicating through a first user device, and a temporal identifier is created for the user and provided to the first user device. Prior to expiration of the temporary key, login credentials provided by the user on a second different user device are received. The temporal identifier is re-created for the user and provided to the second different user device. A first request is received from the first or second different user device. The temporal identifier is stored and an identifier associated with the device. A second request is received from the other device. A device identifier for the first and second different user device are linked in association with the temporal identifier. The linking is used to respond to the second request.

Abstract: In one aspect, a method includes electing one of a plurality of browser tabs at a client device as a master browser tab based on a timer value associated with each of the plurality of browser tabs, each of the plurality of browser tabs running web pages or web applications maintained by a common service being served by one or more servers, issuing a request from the master browser tab to the one or more servers, receiving a response to the request including a time value indicating the next time a request should be sent to the one or more servers at the master browser tab, updating, by the master browser tab, a local storage accessible by the plurality of browser tabs with the time value and resetting the timer value at each of the plurality of browser tabs according to the time value in response to receiving the response.
