Provided in the present disclosure are a camera apparatus and a mobile terminal. The camera apparatus of the present disclosure comprises: a camera assembly; a rotary shaft that is fixedly connected to the camera assembly, a first gear being fixed at an end of the rotary shaft that is away from the camera assembly; a transmission component that is fixed on the rotary shaft and that abuts against the camera assembly; a screw rod that is rotationally connected to the transmission component, a second gear being fixed on the screw rod, and the screw rod and the rotary shaft being arranged in parallel; and a control structure that is connected to the screw rod, the control structure driving the screw rod to rotate, and the screw rod rotatingly driving the transmission component to move along the central axis of the rotary shaft.

Implementations relate to a moveable display system. In some implementations, a control unit includes a first support and a second support coupled to the first support. The second support is linearly translatable along a first axis in a first degree of freedom with respect to the first support, and at least a portion of the second support is linearly translatable along a second axis in a second degree of freedom with respect to the first support. The control unit includes a display unit rotatably coupled to the second support. The display unit is rotatable about a third axis in a third degree of freedom with respect to the second support, and the display unit includes a display device.

A yoke for a suspension system for a medical lamp comprises a rigid yoke member having a first end and a second end, a first revolving joint-component fixed to the first end, wherein the first revolving joint has a first rotation axis, and a second revolving joint-component fixed to the second end, wherein the second revolving joint has a second rotation axis. The first rotation axis is included in a plane and the second rotation axis intersects the plane or is included in the plane, and the first rotation axis and a projection, onto the plane, of the second rotation axis intersecting the plane or the second rotation axis included in the plane enclose an angle (α) of more than 0 degrees and less than 90 degrees.

An articulating arm assembly for a passenger seat includes a static portion attachable to the passenger seat, a rotation portion attached to the static portion such that the rotation portion is pivotable about a rotation axis, an arm body attached to the rotation portion, such that the rotation portion and the arm body are movable between a stowed position and a deployed position, and a wiring portion disposed inside the arm body and extending from the arm body into the rotation portion. The wiring portion extends parallel to the rotation axis from the rotation portion toward and into the static portion.

The wiring portion extends parallel to the rotation axis from the rotation portion toward and into the static portion.

An interactive information system includes a first frame, a second frame, and a first inter-frame cable. A first interactive module is arranged in the first frame and includes a first display module; a first touch input module; at least one first user input device; a first control module bridge board configured to transmit intra-frame electrical signals; a first interactive module bridge board configured to transmit inter-frame signals; and a first intra-frame cable. A control module is arranged in the second frame and includes a logic module configured to generate the first GUI and to perform function of the interactive information system based on user inputs. The first interactive module and the control module are electrically coupled via only the first inter-frame cable. Both the first frame and the second frame contain an electro-magnetic (EM) shielding material.

A display device can include a display; a mounting bracket coupled to a rear surface of the display; a first arm connected to the mounting bracket for tilting the mounting bracket up and down; a second arm connected to an end portion of the first arm and the first arm being configured to rotate based on a first swivel shaft disposed in the second arm; a third arm connected to an end portion of the second arm and rotates based on a second swivel shaft disposed in the third arm; a pillar connected to the third arm and the pillar being configured to move up and down; and a fixing part configured to be fixed to an external object, in which the pillar is connected to an upper surface of the fixing part and rotates based on a third swivel shaft disposed in the fixing part or the pillar.

A modular coupler coaxially mountable with a mast includes a first plate, a second plate and a column axially extending between the first and second plates. An arm is rotatably attached to the column and generally transversely extends therefrom and beyond a radial extent of the first plate and of the second plate. A mounting bracket projects from the arm along a portion of the arm outside the radial extent of the first plate and of the second plate. The mounting bracket is configured to removably mount a first surveillance equipment thereto. A motor is mounted to the arm outside the radial extent of the first plate and of the second plate and is configured to rotate the arm about the column.

An angle-adjustable supporting mechanism that includes a knob-type locking mechanism and a rotatable holder is provided. The knob-type locking mechanism has a base, a knob, and a latch member. The base has a receiving space and a supporting portion. The knob is rotatably received in the receiving space. The latch member is movably received in the supporting portion in a linear direction. The latch member has a bolt, a first stressed part, and a second stressed part. The bolt is disposed at one side of the first stressed part. The first stressed part is disposed between the bolt and the second stressed part. When the knob is rotated in different directions, the bolt of the latch member is drove to lock or release.
