  • Publication number: 20150002409
    Abstract: A convertible computer is provided. The convertible computer includes: a base housing, a touch housing, and a hinge unit. The base housing is equipped with a built-in control module for determining an angle between the base housing and the touch housing according to rotation of the hinge unit, and controlling the touch screen unit and the electrochromic unit according to the determined angle. When the angle exceeds a preset opening angle, the built-in control module enables the electrochromic unit to present a virtual keyboard, and the built-in control module receives inputs corresponding to manipulation of the virtual keyboard. When the angle is less than a preset closing angle, the built-in control module enables the touch screen unit, and the built-in control module receives inputs corresponding to manipulation of the touch screen unit.

  • Publication number: 20140247015
    Abstract: A battery is provided. The battery includes a battery cell, a connector, a universal serial bus, a first micro control unit and a second micro control unit. The connector has an enable pin for determining whether the battery is electrically connected to a portable electronic device through the connector. The first micro control unit is coupled to the enable pin and the second micro control unit is coupled to the universal serial bus. When it is determined that the battery is connected to the portable electronic device, the first micro control unit is enabled to perform a charge/discharge process on the battery cell through the portable electronic device. When it is determined that the battery is not connected to the portable electronic device, the second micro control unit is enabled to electrically connect the battery cell to the universal serial bus.

  • Patent number: 6711004
    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.

  • Patent number: 6654233
    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.

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 engine 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.
