The present disclosure relates to the technical field of photography and videography equipment, and in particular to a rotating assembly, a supporting stand, and a photographing device. The rotating assembly comprises a head adjusting structure including a first button, a first toothed disc, a second toothed disc, and a first elastic member. The first toothed disc is fixedly connected with a first head connector. The first elastic member is configured to enable teeth on the second toothed disc to mesh with teeth on the first toothed disc. The first button is configured to overcome an elastic force of the first elastic member under the action of an external force, so that the teeth on the second toothed disc are disengaged from the teeth on the first toothed disc. The angle of the first head connector fixedly connected to the first toothed disc is adjusted by using the first button, the first toothed disc, the second toothed disc, and the first elastic member, so that the angle of an external device, such as an image acquisition apparatus, mounted to the first head connector can be adjusted without using a separate head, which contributes to cost saving.

A crop management system including at least one crop monitoring subsystem including at least one crop sensor assembly for sensing at least one crop growth parameter in a predetermined region, at least one field monitoring subsystem including at least one field sensor assembly for sensing at least one field parameter in the predetermined region, an analysis engine receiving an output from at least one of the at least one crop monitoring subsystem and the at least one field monitoring subsystem and being operative to identify at least one anomaly in at least one of the parameters and an anomaly locator operative to provide an output indication of spatial coordinates of at least one location of the at least one anomaly.

A gimbal photographing device includes a fuselage; a folding mechanism, connected to the fuselage; and a gimbal camera, connected to the folding mechanism. The gimbal camera is foldable and unfoldable relative to the fuselage via the folding mechanism. A power switch is disposed on the fuselage. The folding mechanism includes a base connected to the gimbal camera. When the gimbal camera is unfolded relative to the fuselage, the base is configured to abut against the power switch to turn on the gimbal photographing device.

A camera support includes a post, a gimbal assembly, and a mounting member. The mounting member couples the gimbal assembly to the post for rotation of the gimbal assembly about a pan axis coincident with a longitudinal axis of symmetry of the post. The gimbal assembly includes a roll cradle, a tilt body and a second mounting member. The roll cradle is movably secured to the first mounting member for rotation about a roll axis perpendicular to the pan axis. The tilt body is movably mounted to the roll cradle for rotation about a tilt axis perpendicular to both the pan axis and the roll axis. The second mounting member is connected to the tilt body for attaching a camera to the tilt body.

An articulated mechanism is included in an articulated pointing system. The articulated mechanism includes first, second, and third spherical joints, and a first, second, and third lever. The first and second spherical joints are linked by the first lever. The first lever includes a first projecting portion. The first and third spherical joints are linked by the second lever, the second lever including a second projecting portion projecting in an opposite direction of the first projecting portion. The second and third spherical joints are linked by the third lever, such that the longitudinal axes of the first lever and of the second lever are perpendicular. The articulated pointing system includes a basement platform and a mobile platform joined by two articulated hinges. The hinges are moved by actuators. The articulated mechanism has the first lever attached to the mobile platform and the second lever attached to the basement platform.

A display device includes a screen, a screen support and a fixing module. The screen support is pivotally connected to the screen, and the screen support includes a first end and a second end. The fixing module is detachably connected to the screen support and includes a first sub-component and a second sub-component. The first sub-component has a first surface and a second surface, and the first sub-component is selectively connected to one of the first end and the second end. The second sub-component has a third surface and a fourth surface, and the second sub-component is configured for clamping a board. One of the first surface and the second surface of the first sub-component and one of the third surface and the fourth surface of the second sub-component are detachably connected.

The bone or chew toy holder is a device that is adapted to support a chew toy or a pet treat at an elevation that is adapted to be consistent with an applicable pet animal. The bone or chew toy holder is constructed of a base that may be weighted. The base includes a pole that extends vertically from the base. The pole is attached to a spring member that in turn is attached to a bracket. The bracket is used to attach to at least one clamp member. The at least one clamp member is adapted to support a chew toy or pet treat.

An assembly includes a first structure, a first bearing assembly, and a second structure. The first structure has a first predetermined stiffness, and the first bearing assembly is mounted on the first structure. The second structure, which has a second predetermined stiffness, is mounted on the first bearing assembly, whereby relative motion about a first rotational axis is allowed between the first and second structure. At least one of the first structure and the second structure distort when a force is supplied thereto along the first rotational axis, and the distortion of at least one of the first structure and the second structure imparts a first preload force on the first bearing assembly.

An apparatus for growing plants in a grow room includes an enclosure having a window. The enclosure contains a grow lamp that is arranged to direct light downward through the widow toward the plants. A blower is coupled with the enclosure to drive a flow of air through the enclosure. A gantry apparatus supports the enclosure in the grow room for movement above the plants.
