An apparatus can be configured to position 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.

A desk has a base that rests on an underlying floor surface, a work surface that is supported by the base, and a seat that is rotatably connected to the base for rotation between a first position, located in a conventional position behind the desk so a person may sit at the desk, and a second position, located to one side of the desk so that a person may instead stand at the desk. The seat is adjustable radially relative to its axis of rotation, vertically up and down relative to the floor surface, and angularly toward its axis of rotation.

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 adjustable desktop assembly includes a base frame having two inwardly tilted sliding plates at two opposite lateral sides thereof and a mounting unit at a rear side thereof for fastened to an external support frame assembly, an adjustment mechanism including a sliding base coupled to the bottom side of the base frame and an adjustment unit, two clamping plates bilaterally mounted in the sliding base, a lead screw mounted in the adjustment unit, and a pressure block affixed to the lead screw and movable with the lead screw between a locking position where the pressure block is abutted against an abutment block of the adjustment unit to lock a desktop to the base frame and an unlocking position where the pressure block is released from the abutment block for allowing adjustment of the forward and backward position of the desktop relative to the base frame.

A portable desk tray table, which has at least one clamp assembly, a frame assembly, and a table assembly. The at least one clamp assembly has an upper jaw and a lower jaw. The frame assembly has an upper rod, a lower rod, and first and second laterals rods with respective table supports. The at least one clamp assembly is mounted onto the frame assembly. The frame assembly further has a collapsible bracket coupled to the lower rod. The table assembly has an upper face and a lower face and is coupled to the frame assembly through the table supports. The lower face has first and second sets of tension holders to secure the collapsible bracket. The table assembly is collapsible and the at least one clamp assembly mounts onto an elongated structure which is secured by the upper jaw and the lower jaw.

An office desktop organizer system including a rigid, tubular section with a triangular cross-section joinable with more sections in series via a connector joint in between sections and end caps covering the opposite ends of the tubular sections. The connector joints may be straight or have a bend. Add on office implements, such as a storage shelf, a drawer, a pencil box, a tape dispenser, a bin, a phone dock, a note pad stand, a USB port, or an AC outlet power center, each having an overarching arm, are connectable to the tubular section by engaging the overarching arm thereto. Eyelets in the end caps and connector joints allow the tubular section to be mounted to a wall using a screw, push pins, tape, etc. where the screw or pin head fits into the eyelet.
