A support apparatus for use to support a user's hand region in a neutrally aligned position during use of a computer mouse on a flat surface is provided. The support apparatus includes a main body disposed on the flat surface, and a cushion member coupled to the main body and having a pair of side walls continuously connected to a lower wall to form a generally U-shaped member, the U-shaped member having a slanted cutout that extends from the front end of the U-shaped member to one of the pair of side walls of the cushion member. The cushion member receives the user's hand region to permit the pair of side walls to conform around the wrist and the lower wall of the cushion member to conform to the palm portion. The cushion member supports the user's hand region as the fingers and thumb perform work with the computer mouse.

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.

Disclosed is a movable wrist support device for elevating and enabling natural motion of the hand/or wrist of an individual when the individual is using a computer input device. The movable wrist support device includes a base member, a wrist support member, and one or more magnets for magnetically levitating the wrist support member a distance above the base member when the wrist support member is positioned above the base member. The movable wrist support device can include magnetically susceptible material that is magnetically attracted to the one or more magnets. Also or alternatively to the magnetically susceptible material, the movable wrist support device can include a slide assembly upon which the wrist support device rests in use of the movable wrist support device.

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.

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.

The present disclosure relates to an adjustable workstation for attaching to a support surface. The workstation includes a base having at least one fastener for securing the base to the support surface and a column attached to the top surface of the base. The column includes a lift configured to move between a lowered position adjacent to the support surface and a raised position located between the top end and the bottom end of the column. Attached to the lift is a worksurface having a front edge, and an extending member connects the lift to the worksurface. The extendable member is configured to adjust the location of the worksurface longitudinally from a retracted position to an extended position, wherein the front edge of the worksurface is vertically alignable with the front edge of the support surface when the extending member is in the extended position.

An intelligence computer desk and chair system includes a platform, a carriage, and a control unit. The carriage is located on the platform. The control unit is electrically connected to the carriage. The control unit controls the carriage to move relative to the platform according to a built-in program.
