A multipurpose with an integrated computer system uses a desk and a drawer computer to provide a user with enhanced safety for themselves and their data. The desk has a support structure, a tabletop, an antiballistic shell, a concealment cavity, a computer enclosure, and a storage compartment. The support structure is a rigid frame onto which the tabletop is mounted. The antiballistic shell is a protective layer of material that wraps around the lateral surface of the support structure so that bullets and flying debris cannot harm the user or the drawer computer. The concealment enclosure is a cavity within the desk that functions as a personal bunker into which the user can crawl. The drawer computer is a personal computing device that is mounted within the computer enclosure. Finally, the storage compartment is a drawer or cabinet that can be used for storing personal items.

A workstation includes a working surface, a channel within the working surface, a rail positioned within the channel, and a clamp mechanism having an accessory and an actuator operable to removably couple the clamp mechanism to the rail. The actuator includes a first side that has a first manually engageable surface and a second side that has a second manually engageable surface. The actuator is movable to a first position in which the clamp mechanism disengages the rail when a force is exerted on the first manually engageable surface, and is movable to a second position in which the clamp mechanism engages the rail when a force is exerted on the second manually engageable surface.

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.

A lifting mechanism for desk including a first bracket, a second bracket, and at least one lever assembly is provided. The first bracket includes a first plane. The second bracket includes a second plane. The lever assembly is connected between the first bracket and the second bracket so that the first bracket moves close to or moves away from the second bracket through the lever assembly, and the first plane is tilted relative to the second plane when the first bracket is away from the second bracket. The lever assembly includes at least two levers, and lengths of the at least two levers are different.

This disclosure provides an adjustable ergonomic workstation that includes first platform and a second platform that is coupled to and positioned below the first platform, wherein the first platform may be moved between at least a lowered position and a first raised position and wherein the coupling of the second platform to the first platform includes a tilt adjustment assembly wherein the second platform may be adjusted between at least a first angular position and a second angular position relative to the first platform.

Described is 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.

A support assembly includes a stand having an underside surface for placement on top of a flat screen device and an upper surface for supporting at least one object; a mount located on the underside surface of the stand, the mount providing a plurality of holes or grooves; a first set of ratchets including a plurality of extensions for insertion into the plurality of holes or grooves; an arm presenting a second set of ratchets; and a fastener for connecting the arm to the mount, causing (i) the plurality of extensions to be inserted into the plurality of holes or grooves and (ii) the first set of ratchets to engage the second set of ratchets, setting the arm at an angle so that a free end of the arm engages the flat screen device while the stand extends at least substantially horizontally from the top of the flat screen device.

An electrically-lifted computer desk and office desk thereof, wherein the computer desk comprises a bottom plate, a driving mechanism, an intermediate support member, a first side-support member, a second side-support member and a face plate, wherein the driving mechanism is fixedly disposed on the bottom plate; the face plate is fixedly disposed on the first side-support member and the second side-support member; and the driving mechanism drives the face plate to rise or fold via the intermediate support member, the first side-support member and the second side-support member.

A desk having a bottom plate, a face plate movably coupled to the bottom plate by one or more support members, a motor configured to selectively move the face plate upward and downward with respect to the bottom plate, and a control mechanism. The control mechanism can have a first sensor device coupled to an upper surface of the bottom plate, the first sensor device having one or more first optical sensors, and a second sensor device aligned parallel to the first sensor device and coupled to a lower surface of the face plate, the second sensor device having one or more second optical sensors in communication with the one or more first optical sensors. The control mechanism can be configured to stop the motor from moving the face plate in response to an object between the first sensor device and the second sensor device.

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.
