A mobile workstation comprises a wheeled base, a height-adjustable post assembly fixedly coupled to the rear end of the wheeled base, and a tray assembly fixedly coupled to the top of the post assembly. The post assembly has a four-post construction, with upper and lower vertical posts pivotally connected to a pair of linking posts. To accommodate different users, the post assembly is designed to articulate between an upper position and a lower position through a primarily vertical travel path. The four-post construction of the post assembly disperses the weight of the tray assembly, thereby reducing the manual force required to implement height adjustment. The planar, primarily vertical, travel path undertaken by the post assembly during height adjustment maintains the workstation center of gravity to a centralized location in the base, thereby minimizing the use of counterbalances to ensure stability. As a result, the workstation is lightweight and easily maneuverable.

A foldable handheld gimbal includes a handle, a first motor arranged at the handle and configured to drive a load to rotate around a first motor shaft, a first connection bracket, a second motor configured to drive the load to rotate around a second motor shaft, a second connection bracket, a third motor configured to drive the load to rotate around a third motor shaft, a carrier structure configured to carry the load, a first hinge structure, and a second hinge structure. The handle includes a top, a bottom, and a side wall arranged between the top and the bottom. The first connection bracket and the second motor respectively rotate around the first hinge structure and the second hinge structure to switch the handheld gimbal among a plurality of states. The first motor and the second motor are respectively arranged at the top and the bottom of the handle.

Techniques are disclosed for systems and methods for nested gimbal assemblies. A gimbal system may include a base, a yoke, and a gimbal assembly rotatably connecting the yoke to the base. The gimbal assembly may include a motor, a bearing, and a ferrofluid seal. The motor may be configured to rotate the yoke relative to the base about a rotational axis. The bearing may be seated within the base and permit rotation of the yoke relative to the base about the rotational axis. The ferrofluid seal may be positioned to seal an interface between the yoke and the base. The motor may be positioned within an inner diameter of the bearing. The bearing may be positioned within an inner diameter of the ferrofluid seal.

A display device includes a head including a display panel, a stand supporting the head, and a moving assembly coupled to the head and to the stand, the moving assembly including a rotational assembly for rotating the head and a tilt assembly for allowing the head to be inclined, the rotational assembly includes a base and a rotating plate rotatably disposed at the base, the tilt assembly includes a holder fixed to the stand, a rotating body coupled to the base and rotatably coupled to the holder, the rotating body having a rotational axis intersecting a rotational axis of the rotating plate, and an elastic member disposed between the holder and the rotating body, wherein a first end of the elastic member is coupled to the holder, and wherein the rotating body is supported by the elastic member at a position adjacent to a second end of the elastic member.

A mobile self-unloading observatory is presented for transporting observation equipment such as a telescope to a remote location, with a subsequent automatic setting up the equipment for observation. The observation equipment is transported on a suspended platform that protects the equipment against shock and vibrations. At the remote location, a self-leveling telescopic pier is extended to the ground under the chassis of the observatory, and released from being held within a frame of the observatory. The telescopic pier is extended towards the platform to support the observation equipment over the ground. The transportation, the setting up, and the teardown of the equipment may be performed without having to manually handle heavy or bulky objects.

A pivotal supporting device includes a supporting base, a pivot shaft disposed on the supporting base, a supporting arm having a plate attached to the pivot shaft, two levers having one end portions pivotally attached to the plate with pivot pins, a panel pivotally attached to the other end portions of the levers with pivot axles for forming a parallelepiped structure with the levers and the plate, and a spindle attached to the panel, a carrier attached to the spindle, and a remote member attached to the carrier. One or more spring biasing elements are engaged onto the pivot shaft and one or more spring biasing members are engaged onto the spindle and one or more spring biasing components are engaged between the pivot shaft and the spindle.

A foldable handheld gimbal includes a handle having a rod shape, a first motor arranged at the handle and configured to drive a load to rotate around a first motor shaft, a first connection bracket, a second motor connected to another end of the first connection bracket and configured to drive the load to rotate around a second motor shaft, a second connection bracket with one end of the second connection bracket connected to the second motor, a third motor connected to another end of the second connection bracket and configured to drive the load to rotate around a third motor shaft, a carrier structure fixedly connected to a rotor of the third motor and configured to carry the load, and a hinge structure. The second motor, the third motor, and the hinge structure are arranged at a same side of the handle.

Aspects of the present invention provide a display support arm assembly that includes a proximal housing supporting at least one proximal shaft, a distal housing spaced from the proximal housing and supporting at least one distal shaft, and at least one link extending from the at least one proximal shaft to the at least one distal shaft. The at least one link is coupled for pivotal movement about an axis of the at least one proximal shaft. The display support assembly also includes a gas strut extending between the proximal housing and the distal housing. The gas strut provides substantially constant force throughout a range of the vertical adjustment of the display support arm. The display support assembly further includes at least one torque element associated with either or both of the at least one proximal shaft and the at least one distal shaft.
