Embodiments of the invention include 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 user console for controlling a remote surgical robotic instrument may include an adjustable ergonomic seat assembly comprising a seat pan, where the seat assembly is configurable between a seated configuration and an elevated configuration, and where the seat pan has a higher anteverted position in the elevated configuration than in the seated configuration. The user console may further include a display configured to receive real time surgical information, and one or more controls for remotely controlling the robotic instrument. The display and/or the one or more controls may have multiple positions and change position automatically according to a seating profile associated with at least one user.

A workstation has two work surfaces that have interfaceable complementary concave and convex edges, and which are maintained in the same horizontal plane by moveable arms connecting the undersides of the two work surfaces. The moveable arms are operable to move one of the work surfaces in the horizontal plane both arcuately along the complementary edges and laterally toward and away from the other work surface. The work surface that moves relative to the other may support a keyboard or other computer input device, while the other work surface may support one or more computer monitors. The workstation is useful for any user having the need or desire for a multi-monitor configuration.

A user system for a robotic surgical system, the user system including a handheld groundless user interface device configured to control the robotic surgical system, and a user console. The user console includes a seat and a first adjustable, ergonomic arm support linkage coupled to the seat, in which the first arm support linkage is movable between a folded storage configuration and at least one unfolded use configuration corresponding to at least one of a user characteristic and a surgical task characteristic. The at least one unfolded use configuration may be pre-stored in a database.

A variable height workstation system comprises a base, a variable height platform, a lift mechanism, a lower adjustable pivot assembly, and an upper adjustable pivot assembly. The base is configured to be mounted to a support surface. The lift mechanism is configured to move the variable height platform between a fully lowered and raised position. The lower adjustable pivot assembly is configured to be connected be to the base and the lift mechanism. The lower adjustable pivot assembly comprises a lower adjustable force regulator configured to adjust a force required to rotate a lower pivot member about its first vertical rotational axis. The upper adjustable pivot assembly is configured to be connected to the lift mechanism and the variable height platform. The upper adjustable pivot assembly comprises an upper adjustable force regulator configured to adjust a force required to rotate an upper pivot member about its second vertical rotational axis.

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 angle adjustment mechanism of a storage drawer of a desk for a keyboard contains: two lockers, two connectors, two movable pieces, two retainers, and two adjustment assemblies. The locker includes a locking section and a through orifice. The connector includes a stop plate, a fitting portion, multiple first teeth, and a column. The movable piece includes a connecting section, a passing orifice, and a support section. The retainer includes a first receiving orifice, multiple second teeth, at least one first slot, at least one recess, and at least one second slot. The adjustment assembly includes a drive member having an accommodation space, at least one second protrusion, a second receiving orifice, and a third receiving orifice. The first adjusting member includes a fourth receiving orifice, at least one fourth notch, at least one fifth notch, and a sixth notch. The second adjusting member has at least one post.
