A tray table assembly and aircraft passenger seat arrangement including the same, the tray table assembly including a rail, along which a carriage slides, disposed within an alcove, from which a tray table can be deployed via a link connecting the tray table to the carriage. The link provides both the connection between the tray table and carriage for positioning the tray table horizontally along the rail and the pivotable connections between the tray table, link, and carriage for adjusting the tray table vertically, perpendicular to the rail path. Thus, the tray table assembly may be hidden in the alcove in a stowed position, partially deployed with the tray table vertically offset from the carriage, fully deployed with the tray table outside of the alcove, and any position in between.

A desktop includes a first portion, a second portion, and a linkage assembly attached to the first and second portions. The first desktop portion has a first, substantially planar, upper surface, and an edge. The second desktop portion has a second, substantially planar, upper surface, a proximal edge, and a distal edge. The linkage assembly is configured such that the second desktop portion is movable between a first configuration and a second configuration. At the first configuration, the second desktop portion is substantially coplanar with the first desktop portion, and the proximal edge of the second desktop portion is adjacent the edge of the first desktop portion. At the second configuration, the proximal edge of the second desktop portion is beneath the edge of the first desktop portion, and the second desktop portion is not coplanar with the first desktop portion and is not parallel to the first desktop portion.

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.

Embodiments of a side deployable keyboard tray systems that may include a height adjustment system. Other embodiments may be described and claimed.

An ergonomically designed space saving, collapsible multi-function travel-friendly modular workstation for supporting a broad range of electronic systems, reading materials and the like for users while standing, sitting or on-the-go, and fits in anywhere, anytime is presented. The workstation comprises a support unit, telescopic rod and tripod and is designed to provide needed cooling and ventilation for electronic systems, support healthy postures, and complete comfort and versatility of a multi-function workstation with all the important things needed when working at a desk, thereby improving a user's comfort when using the workstation. Further, the workstation is designed for easy transportation, storage and set up, as well as provide a versatile workspace for a user in many different environments, for everyday use such as note taking, writing, reading, presentations, performing arts and rehearsing while playing a musical instrument, music or conductor stand, etc.

A securing base includes a base seat unit and a clamp unit. The base seat unit includes a base seat formed with a receiving groove, and a securing plate secured to the base seat. The clamp unit includes a clamp member and a bolt member. The clamp member has an engaging segment disposed within the receiving groove, and a clamp segment disposed outside of the base seat unit. The bolt member extends drivingly through the engaging segment and extends rotatably into the securing plate. Rotation of the bolt member drives the clamp member to move along the bolt member, thereby moving the clamp segment to be distal from or proximate to the securing plate.

A desktop workspace that adjusts vertically includes a work surface platform, a base configured to sit on an existing platform, such as a desk, a height adjustable mechanism including at least one set of arms that connect at a pivot point(s) creating a scissoring motion to raise and lower the said work surface platform to various heights. A locking and unlocking mechanism may connect to the height adjustable mechanism. In some cases, the apparatus includes an adjustable mechanism to support items such as a keyboard. In some cases, the apparatus includes elements to raise items such as a monitor to an additional height.

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 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 securing base includes a base seat unit and a clamp unit. The base seat unit includes a base seat formed with a receiving groove. The clamp unit includes a clamp member and a bolt member. The clamp member has an engaging segment disposed within the receiving groove, a clamp segment disposed outside of the base seat unit, and a connecting segment interconnecting the engaging segment and the clamp segment, and cooperating with the engaging segment and the clamp segment to define a clamp space which gradually shrinks in size away from the connecting segment. The bolt member extends drivingly through the engaging segment. Rotation of the bolt member drives the clamp member to move along the bolt member, thereby moving the clamp segment along an axis.
