Abstract: A mobile terminal is provided that includes a housing having an opening, a display provided in the opening of the housing, a bezel provided on the housing, and at least one sensor or a touch screen/sensor provided at the bezel. The at least one sensor or touch screen detects a user selection on the bezel such that an image on the display changes or a command is performed by the mobile terminal. The sensor or the touch screen/sensor also allows images on the main display to be not hidden because items or commands are selected on the bezel.

Abstract: A portable terminal includes a first body having a first touch screen on an outer surface of the first body, a second body having a second touch screen on an outer surface of the second body, and a hinge unit configured to rotatably connect the first body and the second body. The first touch screen and the second touch screen face the same direction in an unfolded configuration, and the first touch screen and the second touch screen face each other in a folded configuration. The portable terminal further includes a rotation preventing unit configured to prevent relative rotation of the first body and the second body in the absence of an action for relative rotation when the portable terminal is in the unfolded configuration.

Abstract: A function-extending assembly and a portable terminal having the same. The function-extending assembly includes a body to which a terminal body is detachably mounted, and having a module mounting unit; function-extending modules detachably mounted to the module mounting unit, and providing one or more functions relating to the terminal body; and a user input unit disposed on the module mounting unit, and receiving a user input information as manipulating units installed at the function-extending modules are handled. Since a plurality of function-extending modules having various functions are applied to the function-extending assembly in a replaceable manner, various extended functions are provided to the portable terminal serving as a single device.

Abstract: The present invention relates to a system and a method for measuring liquid level by image, and more particularly to a system and a method for measuring liquid level by image, which is capable of measuring a liquid level accurately and automatically by photographing a proximity of liquid surface where a staff gage contacts the liquid using an image capturing apparatus, such as a camera, being located apart from the liquid to be measured, and by analyzing the photographed footage. The system for measuring liquid level by image comprises: a staff gage installed in the liquid; an image capturing part provided with a distance from where the staff gage is installed and capturing an image by photographing a proximity of liquid surface where the staff gage is installed; and a level recognition part controlling a capture of the image, wherein the level recognition part receives the image captured by the image capturing part and determines the liquid level.
