An electronic device and a method for controlling a camera module are provided. The electronic device includes a housing, a camera module, a rotating mechanism, and a pushing mechanism. The camera module disposed in the housing. The rotating mechanism is configured to drive the camera module to rotate in the housing. The pushing mechanism is configured to drive the camera module to an outside of the housing when the camera module rotates to a preset orientation.

In an example implementation, a mobile communication device assembly includes a housing having an opening configured and sized to support a display screen of a mobile communication device. A controller is mounted in the housing and configured to communicably couple to the mobile communication device. An angular adjustment assembly is mounted in the housing and including a first motor electrically coupled to the controller; a first gear assembly driveably coupled to the first motor; and a support member coupled to the first gear assembly and extendable, with the first gear assembly, from a first position flush with the housing to a second position angularly extended from the housing.

A display control method includes: obtaining, by a terminal, orientations and display statuses of a first screen and a second screen; determining, by the terminal, whether a trigger event used for adjusting the display statuses of the first screen and the second screen occurs; and when the trigger event occurs, displaying, by the terminal, adjusted display content on the first screen and the second screen based on the orientations and the display statuses of the first screen and the second screen. By obtaining an orientation and a display status of a terminal screen, when the trigger event occurs, the terminal can adjust the display status of the screen in a timely manner, so that a user can perform an interaction operation and interaction display between different screens.

Dust mitigation techniques are disclosed. An example apparatus includes a first component coupled in a movable relationship with a second component. The first component or the second component includes a recess accessible through an aperture. The apparatus also includes a brush disposed at the aperture and comprising fibers configured to prevent intrusion of dust into the recess. The apparatus also includes a vibration device configured to deliver a vibrational stimulus to the brush, wherein the vibration device activates a dust collection mode in response to a first movement of the first component relative to the second component and activates a dust shedding mode in response to a second movement of the first component relative to the second component.

A display control method includes: obtaining, by a terminal, orientations and display statuses of a first screen and a second screen; determining, by the terminal, whether a trigger event used for adjusting the display statuses of the first screen and the second screen occurs; and when the trigger event occurs, displaying, by the terminal, adjusted display content on the first screen and the second screen based on the orientations and the display statuses of the first screen and the second screen. By obtaining an orientation and a display status of a terminal screen, when the trigger event occurs, the terminal can adjust the display status of the screen in a timely manner, so that a user can perform an interaction operation and interaction display between different screens.

A connecting system of a multi-section housing provided at one end face of a first and second housing superposed with their display surfaces at the outsides, comprising: a first shaft vertical to superposed surfaces of first and second housing; and a second shaft perpendicular to the first shaft, wherein if a center line of the first shaft is arranged on a line bisecting the end face to the left and right and the center line of the second shaft is arranged on the superposed surfaces of the first and second housing, the first shaft can be used to allow the second housing superposed over the first housing to be rotated by 180 degrees and, in this state, the first housing can be made to rotate by the second shaft by 180 degrees so as to arrange the display surfaces of the first and second housings on the same plane.

An apparatus includes first and second portions configured for relative movement; and a compression transmission arrangement extending between them and configured to enable movement of the first portion and the second portion towards each other and further configured to transmit compression forces between the first portion and the second portion to limit movement of the first portion and the second portion towards each other. The apparatus further includes a tension transmission arrangement extending between those portions which is configured to enable movement of the first portion and the second portion away from each other and further configured to transmit tension forces between the first portion and the second portion to limit movement of the first portion and the second portion away from each other. Both transmission arrangements may be on the same side of an equilibrium plane of the apparatus.

A mobile terminal includes: a body in which an electronic component is installed; and a movement unit fastened to the body in at least a portion thereof, configured to output information processed in the mobile terminal, and the movement unit being flexible on the body as curvature of the body is varied, wherein the body includes a varied portion whose curvature is varied and fixed portions formed on both ends of the varied portion and having curvature which is not changed, wherein the varied portion includes a plurality of micro blocks formed in a movement direction and configured to form a predetermined curvature and an elastic member formed in the micro blocks and enabling the micro blocks to form a predetermined curvature when external force is applied or when external force is removed.

An optical device detachably attached to a frame fixed to a user's head is provided. The optical device includes a body extending in one direction, a display extending in a direction intersecting the one direction, connected to the body, and disposed to be adjacent to the user's eye when fixed to the frame, so as to provide visual information, and a clip module protruding from the body and caught in one region of the frame.

A multiple screen arrangement for a mobile device that includes a screen module and a communication module for communicatively linking the screen module with the mobile device. The screen module includes first and second screens movably coupled with each other between a first state and a second state, wherein at the first state, the second screen is overlapped behind the first screen in a single screen size manner, and at the second state, the first and second screens are moved side-by-side to provide two viewing windows. The communication module is adapted for receiving data from the mobile device to be displayed on at least one of the first and second screens, such that the first and second screens are adapted for selectively displaying the data from the mobile device between the first state and said second state.
