Abstract: A user terminal combining touch-screen and keyboard functionality, and also combining laptop and flat-pad layouts. The flat-pad layout can be locked into place using sliding pieces. The terminal comprises a base including a keyboard, a first display screen attached to the base along a primary fold line, a second display screen included in the base and located between the keyboard and the primary fold line, and at least one sliding piece for fixing the second display screen in a substantially flat configuration with the first display screen and/or with another part of the base. The first display screen, the second display screen, and the keyboard have substantially the same width, in order to fully utilize the width of the entire user terminal. This user terminal has a simple mechanical structure, having less than three fold lines, and the keyboard may be detached to reveal additional screen space.

Abstract: A full function keyboard is provided for use with a mobile communication device. The keyboard is constructed in two portions which may be pivoted relative to the body of the device between two positions, one in which the keyboard is hidden and the keypad of the device is exposed for normal use and a second in which the two portions of the keyboard are positioned on opposite sides of the screen of the device to allow holding with both hands and operation with the thumb.

Abstract: A mobile telephone has a plurality of user adjustable operating characteristics, such as the volume of an output signal, the ringing volume, and the generation of tones. When moving from one environment to another, such as from an indoor environment to an in-car environment or an out-door environment, it is preferable to modify a plurality of these operating characteristics. In order to facilitate the modification of the plurality of user adjustable characteristics each group includes predetermined values for all these characteristics and the selection of a particular group results in a plurality of characteristics being modified simultaneously. Thus, when moving from one environment to another, a user is only required to make a single menu selection, resulting in a plurality of operating characteristics being modified simultaneously.
