| 20110013810 | SYSTEM AND METHOD FOR AUTOMATIC TAGGING OF A DIGITAL IMAGE - A system for automatically tagging a digital image includes an electronic device having a face detector for receiving a digital image and determining whether the digital image contains at least one face. A faceprint generator generates a faceprint representing a face detected in the digital image. A matching operation attempts to match the faceprint to a reference data item to identify the face represented by the faceprint. If a match is found, a tag generator generates a text tag corresponding to the identity of the face represented by the faceprint, and may associate the tag with the digital image. If a match is not found, the faceprint may be transmitted with an identification request to an external electronic device, which performs the matching operation. Upon matching the faceprint to a reference data item, identification data identifying the face represented by the faceprint may be transmitted from the external electronic device to the originating electronic device. A text tag may then be generated based on the identification data. | 01-20-2011 |

An input device in the electronic device receives a tag input based on the area of interest to be applied to the associated images. In one embodiment, the input device is a keypad that receives a manual tag input. Alternatively, portions of the rendered images may be transmitted to a network server. The server may compare the image portions to a reference database to identify the subject matter of the image portions, and generate a plurality of suggested tags based on the subject matter. | 01-20-2011 |

| 20100267373 | METHOD OF DETECTING INCORRECT CELL IDENTITY IN WIRELESS COMMUNICATION SYSTEMS - By transmitting the Measurement cell identity (MCI), in addition to the PCI PLMN cell identity (PCI), in a request to a node, an MCI to PCI mismatch is early discovered by the node and reported to the source eNode B. The handover procedure can be aborted in an earlier stage, saving time and resources. The node can then also include information in the response to the source eNode B, which makes it possible for the source eNode B to blacklist MCIs and MCI to PCI combinations. This way faulty or faked MCIs or PCIs can be discovered already in the source eNode B, saving even more time and resources. | 10-21-2010 |
