An adjustable support arm utilizing an elastomeric member having a dynamic attachment point to support the weight of an attached object. The adjustable support arm can include a lower bracket that is connected to an upper bracket by an upper arm and a lower arm. The elastomeric member counterbalances the weight of an attached object. The first end of the elastomeric member can be attached to a linkage, which can include a first, second, and third link and the second end of the elastomeric member can be attached to one of the arms. The links can be coupled to each other between the upper and lower arms such that the linkage is dynamically moveable upon movement of the support arm.

A connection assembly and a gimbal device are provided. The connection assembly includes a first connection member, a second connection member and a locking structure. The first connection member is connected to the gimbal. The second connection member is connected to the first connection member. When the locking structure is in a locking state, the locking structure may lock the first connection member and the second connection member. When the locking structure is in a released state, the first connection member and the second connection member may rotate relative to each other, so that the gimbal may be switched between at least two operation postures.

A lens device includes a first lens system including a first lens, a second lens system including a second lens, a moving member configured to move in an optical axis direction of the first lens, and a physical structure configured to move the first lens in the optical axis direction and move the moving member in a direction opposite to a movement direction of a center of gravity of a physical system that includes the first lens.

A translation axis assembly includes a supporting arm, a connecting plate configured to be movably mounted to the supporting arm, 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 center of gravity of the translation axis assembly by adjusting a position of the supporting arm on the connecting plate. The center-of-gravity adjusting device includes a lead screw and a moving member rotatably and movably arranged on the lead screw. The moving member is received by the connecting plate and is fixedly connected to the supporting arm. The moving member includes a threaded hole in a threaded connection with the lead screw.

A method for object tracking. The method includes capturing a sequence of images of a scene, detecting, by a hardware processor, based on a pattern of local light change across the sequence of images, a reflective light source in the scene, comparing, by the hardware processor in response to detecting the reflective light source, a location of the reflective light source in at least one image of the sequence of images and a target position within the at least one image to generate a result, and generating, by the hardware processor based on the result, a control signal for changing a field-of-view of a camera device such that the reflective light source substantially aligns with the target position within the field-of-view, wherein the reflective light source emits an object-reflected light.

A gimbal control method includes obtaining a working parameter of a gimbal, where the gimbal includes an axial arm and a motor configured to drive the axial arm to rotate to drive a photographing device mounted on the gimbal to move in one or more directions. The method further includes obtaining a working parameter of the gimbal when the gimbal is controlled by a remote controller; and in response to the measured working parameter being greater than the working parameter of the gimbal when the gimbal is controlled by the remote controller, controlling the motor to drive the axial arm to rotate to a target attitude.

A payload stabilizer and methods for stabilizing a payload suitable for use with video camera payloads. The support and stabilizing apparatus has a gimbal having two or more mutually perpendicular axes about which motion is generated by at least two of a pan motor, a tilt motor and a roll motor wherein the pan motor is integral to the gimbal handle and surrounds the main post. The stabilizer has a feedback system providing supplemental torques to the payload through a gimbal.

Aspects of the present invention provide a display support arm assembly that includes a proximal housing supporting at least one proximal shaft, a distal housing spaced from the proximal housing and supporting at least one distal shaft, and at least one link extending from the at least one proximal shaft to the at least one distal shaft.
