Abstract: 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.

Abstract: A counterweight balancing system for filming cranes that are mounted on a vehicle and used to film moving images. The filming crane (1) has a rotating center (4) with a counterweight system (2), on one side, and a filming camera (3), on the other side, which oscillate as if on a balance. A pantograph mechanism enables the counterweight system (2) to be maintained in relation to the ground, in the event of any ascending or descending movement of an arm, holding the filming camera (3), as a result of the system being equipped with articulated points (6, 7, 8 and 9), fixed shafts (10 and 11) and shafts (9 and 9?) movable in relation to a central shaft of the crane (5), thereby forming the pantograph mechanism.

Abstract: A dolly used for filming includes a vertical telescopic column having a filming head or camera positioned on the end thereof. The column includes a movable tube placed externally around a stationary main column; the movable tube is connected to the end of the telescopic column. A camera-supporting element is in turn movably mounted on the movable tube, and a tilting mechanism is included as well.

Abstract: The invention relates to improvements to the vertical columns of dollies used for filming, intended for dollies that include a vertical telescopic column having a filming head or camera positioned on the end thereof. The invention includes a movable tube (2) placed externally around the main column (1), which tube is connected to the very end of the telescopic column (1) or mechanism and, as such, moves in relation to the main tube (1). The invention also includes a movable supporting element (3) that is moved by means of the movable tube (2).

Abstract: Device for stabilizing a light beam or images of the type that can be used to stabilize film cameras or light beam emitters, such as a laser emitter or a pulsed laser beam emitter, which includes means for detecting movements in several axes, means for coding the latter and driving means for correcting the unwanted movements of the object to be stabilized (1), in which a stabilized mirror (4) is arranged, upon which the light beam (2) falls, which light beam related the object to be stabilized (1) to the lens captured or emitted by said light beam (2); said device includes a base with a hollow-shaft pan motor (3) which allows said light beam (2) to pass.

Abstract: Device for fine adjustment of the counterweight of a telescopic filming crane, such as the type of crane with telescopic mechanisms wherein unfolding and retraction thereof is compensated for by means of the displacement of counterweights with the aim of maintaining its equilibrium, comprising electronic means which control a movement transmission means (3) on a secondary counterweight platform (2) which regulate the position of the crane counterweight (1), ensuring more precise adjustment of the position of the crane counterweight (1) and its equilibrium in relation to the fulcrum thereof.

Abstract: HEAD FOR FILM CAMERAS, of the type that comprises a supporting frame with means for automated and remotely controlled movement about three orthogonal axles aa?, bb?, cc?, said head (1) frames comprising two “U”'s, one of them being secondary (2) and rotating about the TILT axle bb?, and the other being a main “U” (3) and rotating about the PAN axle aa?, said “U” facing one another and being articulatedly joined, the base of said secondary “U” (2) having a swinging crosspiece (4) that on its inner face supports a curve guide (6) for fixing and supporting that film camera, which curve guide (6) provides rotation along the ROLL axle cc?, said head (1) being joined to its support (5) with resilient damping means against undesirable movements and vibrations of said support (5) and in addition to the known movement axles, namely, PAN aa?, TILT bb? and ROLL cc?, said head (1) is provided with an independent correcting axle dd? having means for performing a correcting movement in the opposite direction to the undesir

Abstract: A support for a film camera includes a modular body which can be mounted at the end of a camera crane. The body has a pivotable camera-supporting platform which is kept level by an electric motor controlled by electronics. The electronics maintain the platform level with the horizon by rotating the platform in response to signals received from another transducer which indicates inclination of the body with respect to the horizon.

Abstract: A computer operated man assisted motion generation system for use with a camera in cinematography. The system responds to the measured or sensed position of a camera support such as a crane or dolly, and determines the desired camera pan, tilt, roll, focus, zoom, etc. based on predetermined correspondence between camera location and camera parameters, and generate movement of the camera and camera control accordingly.

Abstract: An assembly for holding a camera comprising a first section including two flat portions, a sleeve portion from which the flat portions extend so as to enable movement of the sleeve portion, a first and a second pair of tubes extending perpendicularly from an end of each flat portion, a platform slidable supported by the first pair of tubes, a double clamp slidable supported by the second pair of tubes, a second section including a substantially flat upright, a first pair of tubes extending perpendicularly from a lower end of the upright, a double clamp separating the ends of the first pair of tubes, a second pair of tubes extending perpendicularly from the double clamp, the first section being connected with the second section so as to enable relative rotation between the sections.
