A display stand holder with slide rail structure includes a stand body, a pivot member, a display assembly module, and one or more constant-force springs. The stand body has a top end. The pivot member has a first end and a second end. The first end is provided with a pivot portion. The pivot portion is pivotally connected to the top end of the stand body, and the second end is away from the top end with respect to the first end. The display assembly module is disposed at the second end of the pivot member. The display module includes a slide rail assembly. The slide rail assembly includes a guide member and a slide member, and the slide member is slidably assembled on the guide member. The constant-force spring is connected between the guide member and the slide member.

A supporting device is provided and includes: a base; an upright column disposed on the base; a lifting module disposed on the upright column; a constant force arm unit including: a first rotating member rotatably disposed on the upright column and defining a constant first effective force arm; and a first wire wound on the first rotating member; a variable force arm unit including: a second rotating member linked with the first rotating member and defining a variable second effective force arm; and a second wire wound on the second rotating member; and an elastic force module connected to the first wire; where the torques respectively generated in the first wire and the second wire are balanced with each other.

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 mobile workstation can include a head unit assembly. A worksurface can be coupled to the head unit assembly and configured to translate with respect to the head unit assembly between an open configuration and a closed configuration. A glide can be rotatably coupled to the head unit assembly and engaged with the worksurface. The glide can include a latch configured to translate with respect to a glide body of the glide. The mobile workstation can include a worksurface opening mechanism having a locking configuration and an unlocking configuration. The worksurface opening mechanism can include a latch release handle moveably coupled to the head unit assembly. Movement of the latch release handle can transition the worksurface opening mechanism between the locked configuration and the unlocked configuration. A release assembly can selectively engage with the first latch. A lift system can bias the worksurface away from the head unit assembly.

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.

An apparatus for positioning an electronic display 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.

The invention relates to an adjustable bracket for a display device. The adjustable bracket includes a mounting seat for being fixed to an object surface, a pylon for mounting the display device, and a connecting arm with two ends being rotatably connected to the mounting seat and the pylon, respectively. The mounting seat is provided with a lifting means and an adjusting mechanism for adjusting a retraction state of the pylon therein. The bracket is suitable for a variety of display devices of various specifications, and the pylon is adjustable in three dimensions relative to the mounting seat, thereby meeting the use requirements. The power structure is built to protect itself and to avoid safety hazards. A user can adjust the position of the pylon relative to the mounting seat by pulling and pushing, and the installation and debugging operation is simple, and an overall thickness of the bracket is small when the pylon and the mounting seat are closed up, and the storage space occupied by the bracket is small. The setting of the adjusting mechanism solves the problem of premature failure of a boosting unit caused by over-reliance on its own strength.

A support device includes a support structure, a carrier assembly, and an elastic assembly. The carrier assembly is configured to support a display device. The carrier assembly ascends and descends relative to the support structure. The elastic assembly is connected to the support structure and the carrier assembly and provides different support forces to the carrier assembly to support display devices of different weights.

An articulating support arm includes a base, a first set of control arms having proximal ends and distal ends, with the proximal ends of the first set of control arms being pivotally connected to the base. The support arm further includes a second set of control arms having proximal ends and distal ends, with the proximal ends of the second set of control arms being disposed forward of and pivotally connected to the distal ends of the first set of control arms. The distal ends of the second set of control arms also are pivotally connected to a control head, and a locking assembly selectively prevents pivotal movement of the control arms, so as to provide vertical adjustment of the control head relative to the base.
