20150161665 | SYSTEM AND METHOD OF PREDICTING A LOCATION OF A CONSUMER WITHIN A RETAIL ESTABLISHMENT - The disclosure relates to systems and methods of predicting one or more locations to which a consumer will travel within a retail establishment during a current shopping trip based on prior shopping histories, current in-store behavior, and demographic information. The system may make the predictions based on a model of a population of consumers to determine correlations between prior shopping histories and demographic information and locations visited during previous shopping trips. A particular consumer's shopping histories, current in-store behavior, and demographics may be used to identify an appropriate model for the consumer. The system may use the model to make the predictions and provide information such as incentives based on the predictions. | 06-11-2015 |

20080253550 | Activating Private Access Points For Wireless Networking - A unique identifier is associated with a personal access point. The personal access point is distributed to an end user, who sends a text message including the identifier. Within an automated computer system, the text message is received, a billing account is associated with the personal access point on the basis of the text message, and the personal access point is activated to provide wireless access to a network. | 10-16-2008 |
20100113006 | CELL CALIBRATION - A system and method for enabling an access point to transmit a pilot signal to a mobile device operating in a specified location until a pilot signal acknowledgement is received from the mobile device indicating the pilot signal was detected at the specified location. The system and method further enabling the access point to automatically set an operational power level for the pilot signal based on a power level at which the pilot signal was being transmitted when the pilot signal acknowledgement was received. | 05-06-2010 |

20110206054 | DATA SESSION HANDLING - A method and apparatus to transfer a data session from one device connected to a residential gateway to another. The transfer is completed within the residential gateway, without routing data through the service provider's network. In one embodiment, a native address of a communication device engaged in an active data session is stored in a memory as a temporary device address. A session address in memory is set equal to the stored temporary device address and the temporary device address is associated with the session address in memory. When a request to transfer the data session to another device is received, the temporary device address in memory set to the native address of the new communication device and the session history is sent to the new device. Any new data received in the session, intended for the original device, is routed by a data session handling engine to the new communication device. | 08-25-2011 |
