The present disclosure provides a display screen bracket. The display screen bracket includes a first support body configured to carry a display screen, a second support body disposed opposite to the first support body, and a first linkage mechanism configured to connect the first support body to the second support body. By means of linkage of the first linkage mechanism, a display screen is swingable about a first axis of the display screen. In this way, watching requirements for different positions and angles are satisfied.

A support system for a display device includes a first arm configured to extend from a support surface. A second arm is rotatably connected to the first arm. The second arm has a range of movement relative to the first arm. A tilt head is rotatably connected to the second arm and configured to connect to a display. A first biasing member is positioned in the second arm and configured to provide a first counterbalancing force to the second arm to offset a load of the display. A second biasing member is positioned in the second arm and configured to provide a second counterbalancing force to the second arm to offset the load of the display. A lockout mechanism is configured to disengage the second biasing member and eliminate the second counterbalancing through at least a portion of the range of motion.

A gimbal photographing device includes a body including a supporting wall and a side wall adjacent to the supporting wall, a folding mechanism connected to the body and configured to rotate around a rotation axis, and a gimbal camera connected to the folding mechanism and having an expanded state and a folded state. In response to the folding mechanism driving the gimbal camera to rotate to the expanded state, at least a portion of the folding mechanism abuts against the supporting wall. In response to the folding mechanism driving the gimbal camera to rotate to the folded state, the gimbal camera fits to the side wall of the body.

The present disclosure relates to a plane-distributed load sharing pressure device and a use method thereof. The plane-distributed load sharing pressure device includes a first-stage balance rod to an Nth-stage balance rod, N≥2. The middle part of the first-stage balance rod is hinged to a force applying member. The two ends of the first-stage balance rod are respectively perpendicular to and hinged to the middle parts of second-stage balance rods. The two ends of the second-stage balance rod are respectively perpendicular to and hinged to the middle parts of third-stage balance rods. Similarly, the two ends of an (N−1)th-stage balance rod are respectively perpendicular to and hinged to the middle parts of Nth-stage balance rods. Force bearing members used for resolving a force applied by the force applying member to target members are arranged at the two ends of the Nth-stage balance rods.

A modular track and dolly system for cinematography includes a set of detachable, human-portable track sections, each including a unitary rigid frame supporting first and second spaced apart guide rails and having at least at least one connection plate at each longitudinal end of the frame providing a precise joint interface surface for aligning adjacent track sections. The rigid frame may include a pair of longitudinally extending chords connected by perpendicular struts and two or more web members extending at an oblique angle relative to the chords and struts. Each track section may also include a lightweight subframe made up of an assembly of longitudinal members and lateral stringers connected together, with the rigid frame being supported on and attached to the subframe. A dolly for carrying a cinematography robot is guided by the guide rails and may include a motor-driven pinion that engages a rack on the track.

A trussed suspended platform having uniform weigh distribution for use as part of a temporary shelter such as a tent or other structure or to hold or hang equipment and other materials off the ground. A modular geometric embodiment includes a polygon shaped center cell, a plurality of polygon shaped body cells, and a plurality of polygon shaped edge cells forming the platform edge and corners, each corner having an anchor bar with attachment holes and hardware for attaching the platform to support posts and for attaching a center extended truss hub structure positioned over the center cell with truss cables extending from the hub to anchored platform corners. A hub and spoke embodiment provides a unique trussing hub assembly for supporting a weight bearing spoke platform. Each embodiment is a sturdy suspend able mobile platform allowing assembly and disassembly in the field.

A motorized pentagram armature comprises a parallelogram with a bridge piece positioned at a centroid base, to enable pivotal mounting of the armature to the bridge piece. Plural motors allow movement of the elements of the armature to allow manual or automated positioning of any article carried on the end of a reach arm, for positional movement of the article.

Particular embodiments disclosed herein provide a joint of a tray arm assembly, comprising a joint body, a shaft configured to rotate relative to the joint body about a longitudinal axis of the shaft, and a slip clutch assembly, comprising a clutch stack, including a plurality of first clutch plates keyed to the shaft and a plurality of second clutch plates keyed to the joint body. The clutch stack further comprises a spring configured to selectively exert a force on the clutch stack, wherein the force compresses the clutch stack causing a friction between the plurality of first clutch plates and the plurality of second clutch plates with respect to a rotation of the shaft relative to the joint body.

The present invention relates to an unmanned remote radiation detector capable of accurately detecting radiation radiating in different directions by approaching a place, where the radiation leaks, from above by the control of a user, the unmanned remote radiation detector having: an unmanned aircraft controlled by the user to fly above a nuclear power facility; and a detection part position adjustment part which is coupled to the unmanned aircraft, enables distance adjustment so as to bring a radiation detection part provided on one side thereof near the nuclear power facility, and orients the radiation detection part toward the nuclear power facility by driving same to incline forward, backward, left and right.

A joint apparatus with two degrees of freedom and a large range of singularity-free motion is provided including a first support, a second support, a pivot coupled between the first and second supports for allowing the second support to tilt in first and second directions relative to the first support, a first linkage coupled between the first and second supports for tilting the second support in the first direction relative to the first support, and a second linkage coupled between the first and second supports for tilting the second support in the second direction relative to the first support.
