A camera dolly includes an electrical system for powering a hydraulic system for raising and lowering the camera dolly arm or pedestal. The electrical system has an on-board or in-board battery, such as a lithium battery, contained within the dolly chassis. The dimensions and mechanical configuration of the dolly may optionally remain unchanged by the addition of the electrical system and lithium battery. As a result, existing camera dollies may be retrofitted with the present electrical system. The present electrical system provides a camera dolly with on-board electrical power for charging the hydraulic system. The camera dolly consequently can operate for long periods of time without access to wall current, and without using a manual pump for the hydraulic system.

A detection system includes a plurality of support posts, cables supported by the support posts, a winding device operable to wind the cable, a lifting and lowering device that is connected to the cable, and is movable in an air when the cable is wound by the winding device, and a detecting device hung by the lifting and lowering device. The detecting device is configured to be moved by the winding device in a region defined by the support posts, and lowered by the lifting and lowering device to detect information concerning an object.

A mobile safety tower having a base assembly that includes a base housing, an inverter, a power source, a communications router, a camera power supply unit a controller, an internally-cabled tube that is adapted to be moved between a retracted position and an extended position, a means for moving the internally-cabled tube between the retracted position and the extended position, a camera, a plurality of data collection sensors, and a solar energy source. The means for moving the internally-cabled tube between the retracted position and the extended position moves the internally-cabled tube between the retracted position and the extended position. A method for a mobile safety tower including moving the internally-cabled tube between the retracted position and the extended position.

A steering with shifting system for a camera dolly, including a steering column that can be connected to steering wheels of a camera dolly by first motion transmission means, the steering column being configured to rotate around its central axis in a plurality of positions from a central position to rotate the steering wheels by the first motion transmission means; a handlebar integrally connected to the steering column and configured to be moved to rotate the steering column in a respective position of the plurality of positions; a support body configured to contain the first motion transmission means, the support body including a bell-shaped sleeve coaxial to the steering column, the steering column being at least partly inserted in the bell-shaped sleeve and pivotable with respect to the bell-shaped sleeve; and a central position indication element configured to engage when the steering column is in the central position.

A mobile platform includes at least one first sensor mounted at a first position on the mobile platform and at least one second sensor mounted at a second position on the mobile platform, where the first position is offset from the second position. The at least one first sensor is configured to capture first data measurements of plants in the growing area. The at least one second sensor is configured to capture second data measurements of the plants in the growing area. Each of the first and second data measurements is associated with a three-dimensional position within the growing area and a time. The first and second sensors are configured to generate at least one common type of data measurement such that at least some of the first and second data measurements represent stereo-spatio-temporal data measurements of the plants in the growing area.

A camera crane mobile base for carrying a camera crane includes a first powered remotely controllable steering system having first and second axle assemblies at a first end of a chassis. A second steering system including third and fourth axle assemblies is provided at a second end of the chassis. A first electrically powered remotely controllable propulsion system includes an electric propulsion motor connected to first and second axles in the first and second axle assemblies. A telescoping center post is pivotally attached to the chassis. An on-board hydraulic system may power the first steering system and the telescoping center post.

A photographing system for an ultralow-height counterweight-free vehicle-mounted jib, comprising a base (10), a rotating part, a jib, and a damping part. The rotating part comprises a housing (1) provided above the base (10), a frame (37), counterweight blocks (36), a servo electric cylinder (35), a motor (38), a pinion (40), and a large gear (41). The servo electric cylinder (35) is connected to a rapid abutting structure (2) by means of a clamping member (43). The rapid abutting structure (2) is connected to the jib. The other end of the jib is connected to a gimbal camera mounting plate (6) by means of the damping part. The damping part comprises damping springs (8) and a universal joint structure consisting of a pitch damping rod and left and right swing damping rods. A air spring (34) is provided between the frame (37) and the clamping member (43). One end of the air spring (34) is connected onto the clamping member (43), and the other end of the air spring (34) is connected onto the frame (37). A jib body is driven by the servo electric cylinder to perform a pitch motion, and the weight carried by the front end of the jib body is balanced by the air spring, so that the system is counterweight-free.

A method for adjusting a pointing angle of an actively stabilized camera is provided. The camera is housed by an active stabilization system configured to stabilize the camera in accordance with a commanded pointing angle. The active stabilization system comprises a steering member rotatable around one or more of a pan axis, tilt axis, and roll axis of the system. The method comprises: deriving a joint angle measurement of the steering member associated with a rotational movement of the steering member and adjusting the pointing angle of the camera, based on the derived joint angle measurement, in a direction of the rotational movement of the steering member, if the joint angle measurement exceeds the threshold window. If the joint angle measurement is within the threshold window, the pointing angle of the camera is actively stabilized in accordance with the commanded pointing angle.

A device for finely adjusting the position of the counterweight of a telescopic filming crane has an electronically controlled motor, acting on a secondary counterweight platform, which automatically finely adjusts the position of the counterweight as the crane's telescoping tubes are extended and retracted.

A camera slider has a base and a tubular hollow arm pivotally attached to the base. A counterweight carriage is supported on the arm on carriage rollers. An electric drive motor moves the counterweight carriage linearly on top of the arm. A slider counterweight is movable from a first position, wherein the counterweight carriage is at or adjacent to a first end of the arm and the slider counterweight is at or adjacent to a second end of the arm, and a second position wherein the counterweight carriage is at the second end of the arm, opposite from the first end, and the slider counterweight is at or adjacent to the first end of the arm.
