Various embodiments concern locking release mechanisms that allow an articulated support arm to be moved between various vertical orientations. A locking release mechanism may include a handle release mechanism positioned within the handle of the articulated support arm, and a gas spring release mechanism positioned within the body of the articulated support arm. The articulated support arm can include a gas spring that remains locked until the handle release mechanism is activated, e.g. by applying pressure to a grip actuator. Other embodiments concern cable management techniques for articulated support arms. Oftentimes, an articulated support arm will include cables routed through the arm that are configured to support an attachment. For example, the cable(s) may be adapted for audio signals, video signals, power, etc. The cable(s) can be readily cleaned and/or serviced when routed through an articulated support arm composed of one or more removable pieces.

An X-ray detector holder stand maintaining the position of a detector is proposed. A pillar erected on a base has a sliding window formed on the front surface of a pillar housing to extend upwards/downwards. A rack is fixed inside the pillar housing to extend perpendicularly. A wire is wound around multiple pulleys to extend perpendicularly to the front/rear side of the rack. A balance weight is coupled to the wire behind the rack inside the pillar housing. An arm includes a sliding block guided along the sliding window, a stopper gear coupled to the sliding block to rotate between a locking position and an unlocking position, an elastic pressurizing means for pressurizing the stopper gear to rotate to the locking position, and a lever means for rotating/operating the stopper gear to the unlocking position. A holder is coupled to an end portion of the arm to enable rotational manipulation.

An adjustable multi-monitor support assembly is shown and described. The assembly includes at least one monitor arm, having a proximate end adapted to be attached to a work surface and a distal end and at least one pivot neck secured to the distal end of the monitor arm. Also provided is a hollow monitor support rail, having at least one shuttle aperture therein, being adapted to receive a plurality of monitor mounting brackets for supporting a plurality of monitors and at least one shuttle, having a top and a bottom end, and at least two glides wherein the glides are attached to the shuttle at the top and bottom ends. The shuttle is disposed within the hollow monitor support rail and aligned with the shuttle aperture and secured to the pivot neck.

An elevatable supporting device for holding a display module which is defined with a normal direction is provided. The elevatable supporting device comprises a frame, at least one rail module, a sliding element, and at least one constant force spring. The rail module includes an outer rail and an inner rail, wherein the outer rail is fastened to the frame and formed with a lateral opening for the inner rail sliding therein. The sliding element is formed with an inner space for the rail module penetrating through. The sliding element is secured to the inner rail so as to slide on the frame. The constant force spring is disposed on the top of the frame and connects to the sliding element at a free end thereof. Thus, the elevatable supporting device is characterized in having a slim structure.

A motion assembly that produces pitch and roll motions includes lower and upper plates. A pivotable coupling having upper and lower shafts extending from its center is coupled between the upper and lower plates. At least two linear actuators are coupled between the plates. Extension and retraction of the actuators pivots the upper plate about the pivotable coupling relative to the lower plate. A vehicle includes two steerable propulsion wheels coupled to a chassis. A lower plate of a pitch and roll assembly, similar to that just described, couples to the chassis via a slew bearing. Seating is coupled to the upper plate. The seating rotates with respect to the chassis via controlled rotation of the slew bearing with reference to the chassis. The seating can be rotated to point in any direction with respect to the chassis regardless of the direction the steerable propulsion wheels move the chassis.

A lifting device is disclosed. A base frame of the lifting device includes a first combination member, a sliding frame, a sliding groove on the sliding frame and having sliding holes, and shafts slidably disposed in the sliding holes. A conveyor is mounted on the two shafts and combined with the combination member, and the sliding frame is combined with the first lifting frame, and a sliding rod of the second lifting frame is disposed in the sliding groove, and a locating member is disposed on the sliding rod and combined with the conveyor. When the second lifting frame is vertically moved, the locating member can drive conveyor to move, and the conveyor can simultaneously drive the two shafts to slide in the sliding holes, and the second lifting frame can be slid on the sliding frame, to adjust the height of the second lifting frame individually.

Disclosed is a spring adjustment supporting arm for a display support. The supporting arm comprises an upright column, a big supporting arm, a medium supporting arm and a supporting arm brace rod. The upright column, the big supporting arm, the medium supporting arm and the supporting arm brace rod are hinged to form a four-bar linkage. The big supporting arm is internally provided with a cavity, and the cavity is internally provided with a spring assembly. It is not necessary to adapt to the weight of a display by means of adjusting a force arm included angle of the spring assembly, and therefore, it is not necessary to arrange a force arm included angle adjustment mechanism, thus simplifying a mechanism of the supporting arm, improving the reliability of production and mounting, reducing production costs, prolonging the service life of a product and preventing potential safety hazards.

Embodiments of the invention include an apparatus for positioning an electronic display. The apparatus can be combined with an existing work surface to provide a multi-position workstation. In some cases the apparatus includes a mounting portion configured to support an electronic display and a keyboard. The mounting portion may be movable with respect to the work surface between multiple positions, including for example, a sitting position and a standing position. Methods for positioning an electronic display and a keyboard are also included.

Method and system allowing more accurate detection and identification of unwanted arcing include novel processing of signal voltage representing recovered power-line current. In one implementation, arc-faults are detected based on numerical analysis where individual cycles of line voltage and current are observed and data collected during each cycle is processed to estimate likelihood of presence of arc-event within each individual cycle based on pre-defined number of arc-events occurring within pre-defined number of contiguous cycles. In another implementation, fast transient current spikes detection can be done by: computing difference values between consecutive line-current samples collected over a cycle, average of differences, and peak-to-peak value of line-current; comparing each difference value to average of difference; comparing each difference value to peak-to-peak value; and, based on calculation of composite of two comparisons, using thresholds to determine if arcing is present within processed cycle.
