A tablet including a plate member, a support rod and a positioning member is revealed. The plate member has a top cover, a bottom cover, and a first slide member. By the movable engagement of a rack with a damper, the top and the bottom covers slide relative to the first slide member. The support rod includes an upper end for supporting the plate member and a lower end assembled on a chair, a bed, a sofa, a table, a tray with wheels or a multi-seater chair. The upper end forms a rotary shaft which is inserted through an insertion hole of the bottom cover to be fixed on the first slide member. The positioning member includes a movable locking pin member. The angle of the plate member can be adjusted by the locking pin member being released from or locked into a positioning hole on the rotary shaft.

A smart desk and barricade provide ad-hoc protection during emergencies and an augmented presentation environment. A first desk tabletop includes a connection positioned on an underside of the first desk tabletop, that is configured for detachable coupling to a desk frame. Removal of the tabletop from the desk frame provides a shield. An interlocking element is positioned on one or more edges of the first desk tabletop. The interlocking element is configured to temporarily connect to an edge of a second desk tabletop. A temporary attachment of the first desk tabletop to the second desk tabletop forms a barricade system. In some embodiments, a computing device is integrated into the desk tabletop. A smart room environment may network the desk with integrated computing device to other computing devices in the room.

A portable outdoor classroom system for teachers and students is disclosed. The system includes a plurality of workstations adapted to accommodate the students and teacher in a seating or standing position each workstation including a seating portion and a work desk portion. A blackboard may be included along with one or more shade sail mounted on posts or logs to protect the outdoor classroom system against sun and inclement weather. Also disclose are pre-school early learning pods designed to support early learners with a wider range of developmental needs and abilities.
