Abstract: A mobile terminal having a floated display unit is provided. The mobile terminal includes a first body unit having a first surface and a second surface opposite to the first surface, a second body, and a hinge unit. The second body unit is shorter than the first body unit, is disposed in a central part of the first surface of the first body unit, and has a first display unit disposed in a first surface of the second body unit opposite to a second surface of the body unit facing the first surface of the first body unit. The hinge unit connects the first body unit and the second body unit. The second body unit is movable about the hinge unit to open/close the second body unit with respect to the first surface of the first body unit.

Abstract: A method of controlling a display unit of a portable terminal includes receiving a signal corresponding to a user gesture from a touch sensor unit located in a peripheral area of the display unit; and activating or deactivating at least part of the display unit according to the signal received from the touch sensor unit.

Abstract: The present invention seeks to provide a dual mode mobile satellite communication unit, which requires low communication cost and very little battery power, does not require always carrying a large unit frame and does not always provide great weight burden on the user. A terrestrial communication portable unit is detachably mounted in the mobile satellite communication unit. The mobile satellite communication unit as base unit does not include a key operating section, a display section and a speech transducer section having a microphone and a loudspeaker, and utilizes those mechanically assembled on the portable unit side for keying and other operations. In an interlocked relation to the removal of the portable unit, the stand-by state of the base unit is turned off. It is thus possible to avoid wasteful battery power consumption on the base unit side.
