Abstract: An electronic device including a first housing, a first lock mechanism disposed in the first housing, a second housing, and a second lock mechanism disposed at the second housing is provided. The first housing has a first surface. The second housing pivoted to the first housing is suitable for rotating relatively to the first housing. The second housing has a second surface and a third surface which are respectively disposed at the two opposite sides of the second housing. When the second surface is closed to the first surface and a first portion of the second lock mechanism is protruded from the second surface, the first portion is locked with the first lock mechanism. When the third surface is closed to the first surface and a second portion of the second lock mechanism is protruded from the third surface, the second portion is locked with the first lock mechanism.

Abstract: An ultrasound transducer apparatus for shaping the ultrasound coverage field per application requirement in both the radiating and receiving mode of operation. Wave coverage field is shaped by forming at least one cut at designated location on the housing wall. A cut on the housing wall of the transducer pot-shaped structural body results into the reduction of wave intensity, either radiating or receiving, toward that direction where the cut is located.

Abstract: In the present invention, a dual-output piezoelectric transformer for driving at least two loads is provided. The dual-output piezoelectric transformer comprises a piezoelectric piece, a set of input electrodes mounted centrally on a first and a second sides of the piece with a first polarization direction along a thickness direction of the piece, and a first and a second output electrodes polarized reversely in a second polarization direction and respectively mounted around surfaces of two ends of the piece with the second polarization direction being a longitudinal direction of the piece.

Abstract: A latch device applied in a tablet personal computer is provided. The latch device comprises a first engagement element and a second engagement element. The first engagement element comprises a hook, button and resilient plate. The hook comprises a sliding cavity, a first hole and a second hole. The first hole and the second hole are positioned symmetrically in two ends of the hook. The resilient plate is mounted against the hook. The button includes a bulge and a stopper pressing on the hook. The bulge is passed through the sliding cavity to slide along the long axis up and down. The second engagement element comprises a hollow and protrusion. The protrusion is in the hollow.

Abstract: A foldable electronic device includes a first body, a second body, a magnetism sensing element and a rotation element. The second body is pivoted on one side of the first body. The magnetism sensing element is disposed inside the first body. The rotation element is disposed inside the second body and includes at least a magnet. When the distance between the magnetism sensing element and the rotation element is equal to or smaller than a first distance, the rotation element rotates to a first angle. When the distance between the magnetism sensing element and the rotation element is greater than the first distance, the rotation element rotates to a second angle, so that a user could open or close the foldable electronic device.

Abstract: A portable computer is disclosed. A triple-hinged supporting assembly, which is employed to connect a display unit with a mainframe unit in the portable computer, can easily change various operation positions of the display unit and even rotate 180° to horizontal, so as to fill different requirements of a user.

Abstract: An electronic device with touch display is disclosed. The electronic device includes a host, a main display apparatus and a touchable display apparatus. The main display apparatus is connected with the host via a joint structure which is able to make the main display apparatus and the host fold against each other and the display apparatus rotate on the host. The touchable display apparatus is installed on the host. When the display function of the touchable display apparatus is disabled, the touchable display apparatus can be used as a touch pad for the host; when the display function of the touch display apparatus is enabled, the touch display apparatus displays the same contents as the display apparatus.

Abstract: A portable apparatus with a mechanism for ejecting an add-on device contained in a socket of the portable apparatus. In a preferred embodiment, the ejecting mechanism comprises two engaging parts that can respectively rotate by rotating along two pivots, and a flexible band connected between the two engaging parts for engaging with the add-on device with a contact surface. When a user pushes the two engaging parts toward the socket, an opposite end across the pivot of each engaging part will move outward from the socket, and the flexible band will be stretched and eject the add-on device.

Abstract: The present invention relates to a support frame for adjusting the height of an image output apparatus. The frame includes a rotatable damping wheel and a supporting foot. When the damping wheel pushes against a side of the supporting foot to form a positioning state, the foot is static to the housing. If the housing is pressed downward, the damping wheel rotates to make the supporting foot move relative to the housing for adjusting height of the image output apparatus.
