The invention discloses a low profile input device for moving a cursor, scrolling a page, or selecting a function on a display of a handheld device. In an embodiment of the invention, a planar joystick ( ) for use moving a cursor on the display of a handheld device comprises a movable sliding button having a first magnet M embedded therein. The button is slid by a user's finger over a second magnet M , an action that distorts the magnetic flux which is detected by a plurality of magnetic flux sensors . The direction and magnitude of the cursor movement on the display correspond to the change in flux caused by the movement of the sliding button.

A portable electronic device, which has a slidingly attached touch screen (DPL ) and a sliding lid (SL ) also slidingly installed on top of the touch screen. A keyboard (KB ) is installed on top of the sliding lid. In a normal state, the display of the device is partly covered by the sliding lid and, thus, protected by the sliding lid against mechanical stress. When necessary, the display can be revealed by moving the sliding lid away from the display, whereupon a cogging (R ) made on the bottom of the sliding lid rotates a cogwheel (CW ), attached inside the device, that touches the cogging. The cogwheel transmits the movement of the sliding lid to a movement that is opposite to that of the sliding lid of the display, through a gear rack R attached to the display. Correspondingly, the device can again be brought to the normal state by moving the sliding lid back on top of the display or the display to underneath the sliding lid, whereupon the cogged surfaces that touch against each other cause the remaining moving element to move, and again bring the device to the normal state.

A turning mechanism for providing a turning motion, and a hinged electronic device. The turning mechanism comprises a power element which is arranged to generate the turning force for the turning motion, and a damping element which is arranged to control the speed of the turning motion. The damping element comprises a substantially cylindrical casing inside of which a spindle is mounted using a clearance fit. The power element is connected with respect to the spindle to allow the spindle to rotate inside the casing along with the turning motion. The clearance fit between the casing and the spindle is provided with an elastic medium which controls the motion of the spindle with respect to the casing and dampens the stopping of the turning motion.

A method in the manufacture of a keyboard for an electronic device, the keyboard comprising a set of separate key caps fitted next to each other for transferring pressings, wherein each key cap is further attached to a common base. In the method, the key caps are separated from a solid piece by laser cutting, the piece being simultaneously attached to said base in such a way that the pieces to be separated from the piece, of which each represents one of said key caps, remain attached to said base even after the cutting.

A hinge structure and a hinged electronic device in order to connect two parts of a foldable electronic device rotatably to one another, the hinge structure ( ) comprising a hinge ( ), about the rotation axis of which the parts ( ) are rotatable with relation to one another, and at least one spring element ( ) which controls the operation of the hinge. The spring element ( ) is attached at its first end ( ) to the cover part ( ) and at its second end ( ) to the base part ( ) such that either end ( ) may freely rotate in the attachment means ( ) of the respective part about a rotation axis that is substantially parallel with the rotation axis of the hinge ( ).
