A portable work support device and support for a key board and a pointing device, such as a mouse, for use by occupants of reclining capable office chairs having an adjustable fitted footrest assembly connected to the chair that will provide the seated chair user the ability to achieve a desired pelvis/feet triangulation stabilization effect while reclined by having the seated user's feet placed correctly in an attached footrest thereby producing a tactile input or cue that will lead to the desired muscle or motor output, causing the seated user to actually sit all the way back in the chair, and to be in a posture biomechanically neutral for using and working on the portable work support device, a work station removably housing the portable work support device, and a foot rest assembly to which a chair can be tethered so that a computer user can be properly positioned in a reclining position in the chair and have reduced posture issues when using the work support device while using computer or like equipment.

A desktop organization and display stand system generally providing an integrated system for desks and workstations that is convertible between a conventional working surface, and a display shelf to support a variety of objects including electronic media, such as a tablet computer, laptop computer, smart phone, electronic display, flat panel monitor, television, books, magazines, other printed materials, other suitable object and/or electronic media, or any combination thereof.

A keyboard mounting assembly includes a base having a base upper surface and a downwardly-extending base skirt adjacent at least one side of the base upper surface. The base skirt has a recessed portion offset inwardly from the peripheral edge of the base upper surface and formed underneath the base upper surface. The assembly further includes a keyboard tray having a support portion configured to support a keyboard. The support portion has a tray upper surface and a downwardly-extending tray skirt extending along at least a portion of one peripheral edge of the tray upper surface. The tray skirt has a projection extending inwardly from an interior surface of the tray skirt and configured for receipt within the recessed portion of the base skirt when the base is coupled to the keyboard tray. The assembly further includes an interlock mechanism between the base and the keyboard tray.

A user input device support apparatus is provided for supporting right or left handed users of a computer keyboard and mouse. The user input support apparatus includes a base configured to couple to a mobile or fixed mounting system. The keyboard support further includes a tray configured for supporting a user input device, such as a computer keyboard. Further, the tray includes a lip, wherein the lip is configured to at least partially engage the base. Here, the tray is further configured to slide with respect to the base, thereby accommodating right or left-handed users of the keyboard and a mouse.

Disclosed is a multi-purpose desk, comprising a desk body and legs; the bottom of the desk body is fixed on the ground through the legs; the middle of the lower part of the desk body is provided with a hollow chamber, the upper parts of both sides of the desk body are provided with drawer parts, and both sides of the desk body are provided with storage cabinets below the drawer parts; the upper part of the desk body is provided with a keyboard chamber, and the keyboard chamber is movably provided with a keyboard drawer; the end of the keyboard drawer is rotatably provided with a drawer panel matched with the keyboard drawer through a magnetic lock; the keyboard chamber is provided with supporting plates on both sides of the keyboard drawer.

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 workstation platform is disclosed. In one embodiment, the workstation platform comprises: a base member having an upper supporting surface including a first set of one or more grooves spanning at least partially across the supporting surface, and a first module including one or more downwardly depending tongues. Each tongue is located in interlocking relationship with a respective one of the one or more grooves to permit sliding adjustment of the first module on or relative to the supporting surface over a range.

A lift structure with adjustment assistance optimized based on ergonomics includes a top, a base, an X-shaped cross arm and a gas spring, wherein the X-shaped cross arm includes a first directional arm and a second directional arm; wherein one end of the gas spring rotates around a second rotating shaft fixed relative to the first directional arm, and the other end rotates around a third rotating shaft fixed relative to the second directional arm, and the first, second and third rotating axes being parallel with each other; and wherein at the reference height, in a plane where an axis of the gas spring is located and is perpendicular to the respective rotating axes, the axis of the gas spring is tangent to a circumference centered on the first rotating shaft and having a set radius, with a tangent point being located on the second rotating shaft.

A portable workstation. The portable workstation comprises a housing having a top wall, a bottom wall, sidewalls, an open end, and a closed end, where the top wall comprises a cut-out portion. A digital display is rotatably coupled to the top wall of the housing by a support arm, where the digital display is rotatable between a first position and a second position. In the first position, the digital display is disposed in the cut-out of the top wall such that the housing and digital display define a hollowed enclosure for storing computer accessories therein. In the second position, the digital display is removed from the cut-out and retained in a substantially upright orientation. The workstation may further include a detachable carrying strap for toting the workstation, where the strap is configured to be worn over a user's shoulder.
