Abstract: A pivot-and-positioning assembly for an electronic device includes a mounting seat, a rotatable member mounted rotatably on the mounting seat, a first engaging member mounted on the rotatable member and rotatable along a circumferential trajectory, and a pair of diametrically disposed second engaging members mounted on the mounting seat. Each second engaging member defines a retaining recess that opens at a tangential direction relative to the trajectory for receiving the first engaging member.

Abstract: A portable electronic apparatus for selectively operating in normal mode and tablet mode includes a trigger device that generates a signal and a trigger value after being activated; a processing center that, in response to the signal, retrieves from the portable electronic apparatus a normal value corresponding to normal mode, and compares the normal value and the trigger value to obtain a comparison result; and an executing unit that, according to the comparison result, selectively executes normal mode and tablet mode.

Abstract: A latch unit is mounted on an electronic device having first and second housings. The latch unit includes a hook member for interlocking the first and second housings. The hook member is mounted in the first housing and has opposite first and second engaging ends. The first engaging end projects from the first housing and extends into and releasably engages the second housing upon movement of the hook member to an engaging position when the first housing is positioned at a first transverse position. The second engaging end projects from the first housing and extends into and releasably engages the second housing upon movement of the hook member to the engaging position when the first housing is positioned at a second transverse position.

Abstract: A positioning unit is mounted on an electronic device and includes a catch member and a locking member. The catch member defines a gap which has a width that is reducible when the catch member moves from a non-catching position to a catching position and that is expandable when the catch member moves from the catching position to the non-catching position. The locking member has an engaging end extending into the gap. The locking member is operable to move the catch member from the non-catching position to the catching position and from the catching position to an urging position. The engaging end of the locking member engages the catch member when the width of the gap is reduced upon movement of the catch member to the catching position. The engaging end of the locking member disengages from the catch member when the width of the gap is enlarged upon movement of the catch member to the non-catching position.

Abstract: A data processing device includes a main body, a display unit, a keyboard unit, and a liquid discharge path. The main body includes a casing and a circuit board. The casing includes an upper case having a top side formed with a tray receiving recess that is confined by an upright peripheral wall. The display and keyboard units are coupled electrically to the main body. The keyboard unit includes a tray and a plurality of keys. The tray includes a bottom wall and a surrounding wall. The liquid discharge path is formed through the surrounding wall and the peripheral wall, and/or through the bottom wall of the tray and the upper and lower cases of the casing, and is adapted to permit discharge of liquid that spills into the tray.
