Abstract: A portable communication device including a casing having a front section and a back section is provided. The back section may at least partly made of an electrically conducting material. The casing also may enclose a ground plane and a radio circuit that is connected to a radiation receiving antenna element and the ground plane. The radiation receiving antenna element is provided in an area of electrically conducting material of the back section of the casing.

Abstract: The present invention provides a method, a computer program, and device for navigation assistance where the method and the computer program may include receiving location information related to the geographical location of a device for navigation assistance, continuously receiving visual information registered by a camera, displaying the visual information received, calculating the geographical coordinates of the device from the received location information related to the geographical location of the device and analyzing the visual information received and relating it to the calculated geographical location of the device.

Abstract: The invention relates to a method for processing a picture file in a mobile communication device. The method includes the steps of obtaining a picture file, detecting a object in the obtained picture file, recognizing the detected object, comparing the detected object with objects in a database, tagging the picture file depending on the comparison, and organizing the tagged picture file depending on the tagging.
