In one aspect of the present disclosure, a gimbal assembly is described for use with an image capturing device. The gimbal assembly includes a motor assembly, a first housing defining an internal compartment that is configured and dimensioned to receive the motor assembly, and a second housing that is mechanically connected to the motor assembly such that actuation of the motor assembly causes relative rotation between the first and second housings. The first housing includes a first guide that is configured and dimensioned to support transmission media adapted to communicate electrical and/or digital signals. The second housing defines a channel that is configured and dimensioned to receive the first guide such that the first guide extends into the second housing through the channel. The transmission media is supported on the first guide such that the first guide routes the transmission media from the first housing into the second housing.

A banner support supports a banner or flag unfurled on the pole. When a preset trigger wind load is exceeded, the banner bracket rotates away from the direction of the wind so as to limit the stress on the pole. The mechanism which enables bracket rotation comprises a disk-shaped cam with a spring-loaded plunger extending from the support arm that biases a cam follower into a proximal cam detent. Subject to the restraint of the cam follower, the cam rotates around a transversely axial cam shaft connected to the support arm. The cam is rigidly attached to the banner bracket, which rotates along with the cam. When the preset wind load is exceeded, the cam follower is forced out of the cam detent, allowing the cam and the connected banner bracket to rotate away from the wind direction. As the banner turns away from the wind, the wind stress decreases, allowing the spring plunger to force the cam follower back into the cam detent, thereby restoring the banner to its rest position.

A brake assembly for braking relative rotational movement of a spindle that is moveable about a central axis relative to a hub. The brake assembly is comprised of a collar comprised of a pair of arcuate leg sections, having a first end pivotally linked together to allow pivoting movement of the leg sections. A frictional surface is provided along the inner surface of each of leg section. An adjustable fastening assembly connects second ends of the leg sections together and clamps the leg sections to the spindle with the frictional surface on the leg sections engaging the outer surface of the spindle. A stop member is connected to the hub and is disposed to engage a surface of the leg sections, wherein rotation of the spindle in a first direction about the axis causes a surface of one of the leg sections to engage the stop and to reduce frictional engagement of one of said leg sections by releasing engagement with the spindle as the spindle moves in said first direction.

A support arm having a proximate support arm segment, a distal support arm segment, a hinge system; and at least one rotation limit stop secured to the hinge system to limit the extent of angular motion of the proximate support arm segment, the distal support arm segment or both, with respect to the hinge system. The rotation limit stop includes a first stop component and a second stop component slidable with respect to the first stop component. When the second stop component encounters a contact point on one of the support arm segments, the angular motion of the arm segment with respect to the hinge system is at a maximum. The second stop component can be secured in a plurality of positions with respect to the first stop component by an adjustment component.

An adjustable holder assembly is disclosed that has a mounting structure and a display support with a center of gravity and being rotatably coupled to the mounting structure for rotation about an axis of rotation. The display support has a support structure and an adjustable counterweight assembly with a counterweight and an adjustment mechanism connected to the counterweight. The counterweight is spaced apart from display support's axis of rotation. The adjustment mechanism is adjustable to move the counterweight in a direction normal to the axis of rotation to move the center of gravity toward or away from the support structure. The adjustable counterweight is configured to provide a force feedback to a user pressing on an input portion of the computer tablet by moving the center of gravity toward or away from the support structure.

A mount for receiving a cylindrical element includes a retention assembly that retains the cylindrical element between the retention assembly and a base. The retention assembly includes arm segments extending from the base and retaining members disposed along at least one of the arm segments. The retaining members are separated from each other by a gap through which the cylindrical element is insertable. At least one of the arm segments or retaining members is resilient so that the gap is widened when that cylindrical element is pushed through the gap. The retaining members retain the cylindrical element between the retaining members and the base until force is applied to pull the cylindrical element back through the gap. A biasing member extends from, and is moveable relative to, the base to bias the cylindrical element against the retaining members while lacking sufficient force to push the cylindrical element through the gap.

The present disclosure described devices and methods for stabilizing a payload. A carrier may be provided. The carrier may manipulate a payload such that the payload is able to rotate about a roll axis by 90 degrees or more. In some instances, the carrier may be directly connected to a component (e.g., gimbal component) configured to permit rotation of the payload about a roll axis. The carrier described herein can have a compact configuration that allows for minimal volume and weight and may be ideally suited for mobile use. Particularly, the carrier may be mounted on an unmanned aerial vehicle (UAV). In some instances, an imaging device may be coupled to the carrier and images having horizontal orientation, vertical orientations, or orientations in-between may be captured and processed.

A gimbal system includes an angle adjusting unit configured to carry an imaging device, a main controller configured to detect posture information of the imaging device, a gimbal control unit configured to control the angle adjusting unit according to the posture information, and a digital video transmission component configured to transmit a digital video signal from the imaging device. The digital video transmission component includes a video converter configured to receive the digital video signal, and convert and compression encode the digital video signal to output a serial differential signal. The digital video transmission component further includes a differential signal transmission line coupled to the video converter and configured to transmit the serial differential signal, and an image transmission unit coupled to the differential signal transmission line and configured to receive the serial differential signal.

A support device includes a support bracket unit mounted on a fixed object, an extension arm unit swingably connected with the support bracket unit to support a movable object, and a flexible unit connected with the extension arm unit and the support bracket unit. The flexible unit includes a stretchable and retractable biasing member and at least one rolling member rollably mounted on the biasing member to slide along the extension arm unit during stretching and retraction of the biasing member. With the rolling member, straightness of the biasing member is maintained, and frictional resistance to the biasing member is decreased so as to enhance smooth operation of the extension arm unit.
