A self-balancing Two-Rotation Driving Mechanism (TRDM) uses parallelogram and has low weight, high load, high accuracy, quick response and good adaptation with multi equipment. A longitudinal rotation motor assembly is constrained fully with a base assembly and drives a longitudinal rotation assembly through connecting rod parallelogram. The lateral rotation motor assembly is assembled in the hub of a longitudinal rotation assembly and rotates an equipment clamping assembly in a lateral direction. Generally, the TRDM can drive equipment clamping assembly in two rotations, with longitudinal rotation in the range of ±45° and lateral rotation in range of ±20°. A rotation limitation is reached when limitation shafts touch the end of respective grooves.

A mounting system capable of mounting objects to support structures. The mounting system includes a wall mount including a display bracket configured to hold the object, a fixed support bracket coupleable to a vertical support structure, and a linkage assembly. The linkage assembly has a low-profile stowed configuration in which the object is held in a raised position close to the support structure. The linkage assembly moves to another configuration to move the object. The object can be held in a lowered position. A biasing mechanism can facilitate convenient movement of the object.

The invention is a monitor arm assembly including a rotation limiter that includes movable tabs to set the rotation limits of the arms with respect to each other or other assemblies. The rotation limiter may include exterior ring activators and outer visual references for the set limitations. The monitor arm assembly also includes a plurality of slide tracks to allow the monitor attached the arm to take a plurality of lateral positions. The assembly may further include a connector to join adjacent slide tracks.

Disclosed is an ultrasonic diagnostic apparatus including an improved actuator to compensate for a weight of an input/output device. The ultrasonic diagnostic apparatus includes a main body, an input/output device coupled to the main body and configured to receive information from a user or output information received from the main body, and a connection device to connect the main body and the input/output device, wherein the connection device includes a shaft having a shaft body, a link frame having a frame body and a shaft coupling portion extending from the frame body to be coupled with the shaft, and an actuator including a torsion spring having a first end supported by the shaft and a second end supported by the link frame, so as to compensate for a weight of the input/output device.

A load-stabilizing apparatus includes a load-connecting member configured to carry a load, a parallelogram mechanism connected to the load-connecting member, and a stabilizing motor drivingly connected to the parallelogram mechanism. The stabilizing motor is configured to drive the parallelogram mechanism to deform, such that the parallelogram mechanism drives the load-connecting member to move.

A stabilization degree adjustment method includes obtaining a stabilization degree adjustment instruction and adjusting a stabilization degree of a stabilization mechanism according to the stabilization degree adjustment instruction. The stabilization mechanism is configured to support a load.

A camera mount that can provide high stability, ease of operation, and flexible configurations for different applications and installation scenarios. The camera mount has an improved attachment mechanism that provides multiple locking positions and strengthened positioning pins. The camera mount has a plurality of anchoring devices capable of securing the camera mount on different curved surfaces.

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.

Support systems and stands for electronic devices include tilt hinges, lift arms, and their component parts. Some tilt hinges include assemblies for guiding and retaining bars or protrusions into preferred positioning within receiver openings to unify the parts, particularly as they move, and to reduce wobble or slop in the joints. Lift arms provide simplified and low-cost guidance and counterbalance mechanisms for controlling movement of the electronic device relative to the base of a stand. In some cases, the lift arms have sheaths to help protect or cover mechanisms while allowing additional space for the mechanisms within the lift arm. Other interconnection systems hide and protect a connector interface between the stand and the electronic device within a housing until unlocked and the connector is moved into an exposed position. These systems improve efficiency, comfort, ergonomics, accessibility, and user satisfaction of the electronic devices and their supports.
