Abstract: A display device which can elevate and rotate to a position includes a base, a controlling member mounted to the base, and a supporting frame. A display is mounted on the supporting frame, and a first magnetic piece is positioned on the controlling member. A second magnetic piece is positioned on the supporting frame. The first and second magnetic pieces are configured to attract each other. The controlling member includes a first elastic piece between the base and the supporting frame. The first elastic piece retracts to enable the supporting frame to rotate. The controlling member can slide to detach the second magnetic piece from the first magnetic piece, and the first elastic piece retracts to allow an upward rotation of the supporting frame thereby changing height of the display.

Abstract: A moored balloon includes a balloon, a wire coupled to the balloon, an antenna, a cable coupled to the balloon, a rotating device hung below the balloon, and a fixing device. The rotating device comprises a rotating unit and a bracket. The rotating unit comprises a bearing seat mounted on the bracket, a bearing unit mounted on the bearing seat, and a shaft passing through the bearing unit and coupled to the balloon. The fixing device comprises a receiving tube for receiving the antenna. The receiving tube is located on the bracket. The shaft moves with the balloon to generate a twisting force, the bearing unit counterbalances the twisting force to prevent the cable being twisted with the wires.

Abstract: A mounting apparatus, able to maintain the relative position of a camera during rotations between portrait and landscape presentations of an electronic device, includes a camera. The mounting apparatus is mounted to an electronic device, which has a display screen. When the electronic device is rotated from a first presentation state to a second presentation state, the camera remains in position above the display screen.

Abstract: A camera assembly includes a camera and a rotating mechanism configured to drive the camera to rotate. The rotating mechanism includes a base, a driving device, a first driving gear, a second driving gear connected with the camera, and a switch gear. The driving device, the second driving gear, and the switch gear are located on the bracket. The first driving gear is located on the base. The switch gear is driven to selectively engage with the one of the first driving gear and the second driving gear. When the switch gear is connected with the first driving gear, the bracket is driven to rotate and rotate the camera on a first plane. When the switch gear is connected with the second driving gear, the driving device drives the camera to rotate via the switch gear and the second driving gear.
