A lens bracket assembly for supporting an imaging device. The imaging device includes a body and a lens connected to the body. The lens bracket assembly includes a mounting plate, a supporting plate configured for carrying the imaging device, and a bracket. The mounting plate includes a first surface and two inner sidewalls extended from two opposing ends of the first surface along a direction substantially perpendicular to the first surface. The two inner sidewalls provide first sliding slots. The supporting plate includes a first side and two outer sidewalls providing second sliding slots, and is slidably disposed on the mounting plate with the second sliding slots matching the first sliding slots at corresponding positions. The bracket is coupled to the first side of the supporting plate, and includes a shape that matches the lens of the imaging device.

A camera rig configured support a video camera or other cinematographic equipment is disclosed. The camera rig includes a first track and a second track movably coupled to the first track. The second track is configured to move along the first track between a first angular position and a second angular position. The camera rig also includes a platform movably coupled to the second track. The platform is configured to support the video camera or the other cinematographic equipment. The platform is configured to move along the second track between a first vertical position and a second vertical position.

A translation axis assembly includes a supporting arm, a connecting plate, and a center-of-gravity adjusting device connected between the supporting arm and the connecting plate. The center-of-gravity adjusting device is configured to adjust a position of the supporting arm on the connecting plate to adjust a center of gravity of the translation axis assembly. The center-of-gravity adjusting device includes a locking assembly configured to allow the supporting arm and the connecting plate to be in a loose fit or to hold tightly to each other.

A damping device includes an upper damping connecting member, a lower damping connecting member opposite to and spaced apart from the upper damping connecting member, a steel wire rope damper disposed between the upper damping connecting member and the lower damping connecting member, and a carrying damper connected with the upper damping connecting member. Two ends of the steel wire rope damper are connected with the upper damping connecting member and the lower damping connecting member, respectively.

The present invention relates to the technical field of vehicle maintenance and device calibration, and discloses a vehicle-mounted radar calibration device and method. The vehicle-mounted radar calibration device includes a bracket apparatus and a radar calibration component. The radar calibration component is configured to be installed on the bracket apparatus and includes a base board. After calibration on the vertical plane of the base board is completed, the radar calibration component is configured to reflect a radar wave, emitted by a vehicle-mounted radar of a to-be-calibrated vehicle, to the vehicle-mounted radar, to calibrate the vehicle-mounted radar. In the present invention, after the vertical plane of the base board is calibrated, the radar calibration component is used to reflect the radar wave emitted by the vehicle-mounted radar to the vehicle-mounted radar.

A base and movable platform are connected by a linearly extendable member, so that a motor may be adjustably located at a desired distance from other machinery which receives power. A motor mounted on such a movable platform may be linearly displaced so that belts, chain, or silent chain or the like may be adjusted to operate at a desired tension. In another embodiment, a motor driving a gear train may be adjusted so that the depth of engagement of meshed teeth and the allowable backlash between a driving gear on the motor and a driven gear may be adjusted and controlled. An automatic belt tension control system may be constructed by adding a tension sensor and a control module configured to maintain operating tensions within a preferred range and optionally to emit alarms or command a shutdown if an unsafe condition is detected.

The present disclosure provides an attachable external display screen for use on electronic devices. The display screen may be removably mounted onto a surface of an electronic device to provide the user with an additional display screen. The attachable display screen may utilize a dual sliding mechanism that allows for the display screen to slide out to different lengths relative to the screen of the electronic device. The attachable display screen may also utilize a torque hinge to pivotally couple the display screen to a frame that mounts onto the electronic device. The attachable display screen is rotatable about both the horizontal and vertical axes, which allows a user to tilt and adjust the angle of the display screen.

An assembly including a channel track for engagement with the surface of a desk, having a generally flat bottom surface, a hollow interior portion and a slot extending the entire length of the channel track; at least two hubs, having a coupling with a bushing for receiving an office accessory; at least two plate nuts disposed in the hollow interior portion of the channel track, and wherein each hub is secured to a corresponding plate nut by a bolt which extends through the hub, through the slot in the channel track and into engagement with the corresponding plate nut; and either a bolt or clamp member for securing the channel track to the desk.

A monopod for mounting to the boat seat mount of a marine vessel, such as a bass boat or speed boat, which is capable of providing power for mobile accessories via a second monopod affixed to the navigation light port of the boat. The monopod is extendable to heights up to or exceeding eight feet (8′) above the deck of the boat, providing exceptional views for recording with a mounted camera while users participate in sports or other events within the boat. A release mechanism allows one portion of the monopod to telescope away from a second portion, thereby extending the monopod.

A method for controlling a multi-screen system includes acquiring a control instruction for the multi-screen system; and controlling a plurality of display screens to move according to the control instruction. The multi-screen system includes a plurality of display screens and a driving mechanism configured to drive the plurality of display screens to move in space.
