Abstract: A cellular telephone handset utilizes an electrically-steered directional antenna to increase the received signal strength when the handset is in a poor signal environment. As a result, the handset reduces the need for an end user to tilt and twirl their head to try and find the direction of the strongest signal strength.

Abstract: Guiding pieces on a bracket cover is engaged with attachment claws on a bracket body. This engagement serves to hold the bracket cover on the bracket body when the bracket cover is set at a first position. When the bracket cover is set at a second position, the engagement between an engagement piece and a hook piece serves to cooperate with the engagement between the guiding pieces and the attachment claws so as to hold the bracket cover on the bracket body. The bracket cover is firmly held on the bracket body when the bracket cover is set at the second position. The bracket cover is thus reliably prevented from detachment from the bracket body.

The invention relates to methods for quickly obtaining and displaying geographic location of a mobile device on its display. These methods can be performed by applying successive fixation steps as outline herein.

Abstract: A method is provided for displaying a message in a mobile communication terminal. According to one example, the method includes the steps of receiving a first message, displaying the first message on a first display of the terminal, and displaying a message preparation window on a second display of the terminal simultaneously with the display of the first message. Since the terminal user can prepare a response text message to a received text message while viewing the received text message, the preparation of the response text message can be more conveniently achieved.
