A system comprises a cantilever structure and a harmonic absorber. The cantilever structure is anchored at an anchor end and connected to a device at a distal end. Use of the device imparts vibrations in the cantilever structure. The harmonic absorber is located at the distal end of the cantilever structure. The harmonic absorber is tuned to a structural frequency of the cantilever structure such that the vibrations in the cantilever structure are damped.

A trajectory record arm is disclosed, on which the connection apparatus is engaged in order to provide the transmission of the motion trajectory of a connection apparatus to a trajectory recording device. The trajectory record arm includes: at least one telescopic bar which is engaged on one side with at least one fastening element and on the other side with the connection apparatus such that freedom of rotation is allowed between the fastening element and the connection apparatus, at least one first sensor for detecting the movement between the telescopic bar and the fastening element, at least one second sensor for detecting the distance change between the fastening element and the connection apparatus based on the change in the length of the telescopic bar, at least one third sensor for detecting the movement of the connection apparatus in relation with the telescopic bar.

This invention discloses a pan-tilt hand holder which features that: It includes a clamping mechanism for holding the mobile terminal, a control device, and a power device are provided, wherein, the frame body is configured to install a pan-tilt, the control device is configured to control the movement of the pan-tilt, and the power device is configured to supply electric power to the control device. The application of the invention achieves not only the handheld movement operation of the pan-tilt, but also the operation with just one hand, which is convenient for use.

A positioning apparatus mounted with at least one linear axis or axis of rotation and a robot on a base and mounted with vibration isolators and the robot includes vibration isolators that are capable of seating and suspending the base and a controller that controls suspension and seating of the vibration isolators in accordance with an operating condition of the robot.

A flat panel TV bracket includes a bracket body and a display hanging plate assembly. The bracket body includes a wall mounting plate, a first rocker arm and a second rocker arm. The display hanging plate assembly includes a hanging plate and a connector. The connector rotatably includes a support plate and a rotating plate. The support plate pivotally connects with a connecting block. The rotating plate fixedly connects with the hanging plate, the lower end of the rotating plate pivotally connects with the lower end of the support plate, and the upper end of the rotating plate slidably connects with the upper end of the support plate. The second rocker arm includes a rotating block; upper and lower arms; and upper and lower arm housings; and an air spring. The air spring rotatably connects with the lower arm on the rotating block and pivotally connects with the connecting block.

A mounting assembly includes a base; a post extending from the base, the post defining a vertical axis; a beam mounted on the post and being pivotable about the vertical axis, the beam comprising a first portion extending in a first horizontal direction and terminating in a first end, and a second portion extending in a second horizontal direction opposite of the first direction and terminating in a second end; an equipment mounting bracket at the first end; a latch along the beam and having an engaged position and release position, wherein in the engaged position the latch prevents the beam from pivoting; and a latch release along the second portion of the beam. A method of accessing equipment mounted on the mounting assembly includes actuating the latch release such that the latch moves from the engaged position to the release position; and rotating the beam about the vertical axis.

An easy extention of a telescopic rod. The telescopic rod extends in the axial direction by a gas forcibly fed to the inside and is provided with a posture control means.

Systems and methods are disclosed for releasably securing items such as health, medical, fitness, and exercise equipment, in which anchor units are securely attachable directly or indirectly to a surface and are securely but releasably attachable to a plurality of items. The anchor unit may have a mounting base attachable to a surface, a fitting bracket that at one end may be permanently attachable or securely but releasably attachable to the mounting base, and an attachment subsystem for releasably, tightly, and securably attaching the mounting base to the fitting bracket. At its other end, the fitting bracket may be attachable to multiple items, or it may be permanently attachable to a selected item.

An articulating arm for balancing a tray for holding tools and equipment such as air tools, grinders, welders, vacuum, and electrical tools off the ground and movable horizontally and vertically to position the tools or equipment near a work area. The arm comprising a tray end and a mount end with an articulating parallelogram arm allowing the tray end to articulate vertically and horizontally with an adjustment mechanism configured to adjust a linkage that interacts with a spring such that the tray end vertically stays when it is released at any elevation.

A gimbal for supporting a load includes at least three rotatably coupled driving axis assemblies and a controller. Each driving axis assembly includes a driving device and a joint arm configured to rotate when driven by the driving device. The controller is configured to control the gimbal to limit a rotation of a first driving axis assembly, and adjust positions of a second driving axis assembly and a third driving axis assembly, respectively, relative to the load, such that the gimbal maintains a forward orientation of the load.
