  • Patent number: 9282476
    Abstract: A REC device of a base station includes a switch instructing unit and an extension signal processor. The switch instructing unit monitors the state of the REC device, and based on a result of the monitoring, determines switching from the REC device to an extension REC device. When the switching is determined, the extension signal processor acquires a signal transmitted from the extension REC device, and requests the switching from the extension REC device. The extension REC device includes an extension signal processor and a digital processor. The extension signal processor receives the switch request from the extension signal processor of the REC device. In response to the received switch request, the digital processor sets the parameters of the REC device in the extension REC device, and establishes a link to a RE.

  • Patent number: 9275270
    Abstract: This invention provides a technique which can enhance personal recognition precision in personal recognition processing of a face in an image. To this end, a management unit classifies feature patterns each including feature information of a plurality of parts of a face region of an object extracted from image data, and manages the feature patterns using a dictionary. A segmenting unit determines whether or not feature information of each part of the face region of the object is segmented, and segments the feature information of the part of interest into a plurality of feature information as new feature information. A registration unit registers a feature pattern as a combination of the new feature information of the part of interest and feature information of parts other than the part of interest in the dictionary as a new feature pattern of the object.
