A method includes receiving selection of a target within an image captured by an image sensor of a payload and displayed on a user interface of the payload, detecting a deviation of the target from an expected target state within the image, generating, based at least partly on the deviation, a payload control signal including a first angular velocity for rotating the payload about an axis of the carrier to reduce the deviation about the axis in a subsequent image, and generating a base support control signal including a second angular velocity for rotating the payload with respect to the axis. When the first and second angular velocities are received, the carrier is controlled to rotate the payload at a third angular velocity about the axis. The third angular velocity is the first angular velocity, the second angular velocity, or a combination of both.

Solar trackers that may be advantageously employed on sloped and/or variable terrain to rotate solar panels to track motion of the sun across the sky include bearing assemblies and other mechanical features configured to address mechanical challenges posed by the sloped and/or variable terrain that might otherwise prevent or complicate use of solar trackers on such terrain.

One embodiment includes a device for solar tracker systems. The device includes a first purlin including a first mating surface configured for frictional attachment to a first side of a torque tube. The first purlin further including a first linear shaped top surface configured for mounting a first solar module. A second purlin includes a second mating surface configured for frictional attachment to a second side of the torque tube. The second purlin further including a second linear shaped top surface configured for mounting a second solar module. The first purlin and the second purlin connect to one another with a fastening clamp that is configured for holding the first purlin and the second purlin against the torque tube.

Examples of the present disclosure are directed toward a control panel display with rotatable mount. An example apparatus includes a control panel mount including a first surface to receive a control panel display and a second surface opposite the first surface. The apparatus further includes a rotatable mount including a first surface and a second surface opposite the first surface. A first hinge mechanism which is rotatable about a first axis may allow the rotatable mount to move between a first operational position in which the rotatable mount is disposed in contiguous contact with a top cover of the apparatus and a second operational position in which the control panel display is disposed within a recessed portion of the top cover. A second hinge mechanism may be rotatable about a second axis orthogonal to the first axis to change a display angle of the control panel display.

A display includes a screen, a stand and a hanging element. The stand is connected to the screen and has a first end and a second end. The hanging element is selectively disposed on the first end or the second end. When the hanging element is disposed on the first end, the hanging element could clamp a first plate; when the hanging element is disposed on the second end, the hanging piece could clamp a second plate, wherein the first plate is perpendicular to the second plate.

A security apparatus secures a laptop, and particularly a convertible laptop, to a mounting surface. The security apparatus comprises a housing assembly, and a first arm assembly and a second arm assembly extending from and retractable into the housing assembly. A first end assembly and second end assembly are mounted to the first arm assembly, and a second end assembly. Each arm assembly secures a first side and a second side of a lower body portion of the laptop. A trapping member is positioned in the housing assembly to lock the arm assemblies. A locking rod has a first end extending outside the support housing and a second end extending into the housing assembly and into engagement with the trapping member, the locking rod configured to move the trapping member into engagement with the first and second arm assemblies.
