A device, comprising: a base assembly including a processor and a crank shaft configured to define a lower axis of rotation (120); a display assembly including a display that is driven by the processor, the display secured by a display mount relative to a display shaft that is configured to define an upper axis of rotation (120); a hollow arm (118) secured to the crank shaft and forming an angle α with said base assembly, such that when the hollow arm rotates around the lower axis of rotation to adjust said angle α, the crankshaft rotates correspondingly, wherein said crankshaft comprises a crankpin such that reducing the α angle causes the crankpin to turn in a counterclockwise direction and this action forces a connecting rod coupled to the crankpin so that movement of the connecting rod compresses a spring that is arranged in the base assembly, and said hollow arm is secured to the display shaft such that when the hollow arm rotates around the upper axis of rotation the display shaft rotates correspondingly; a lower link positioned within the hollow arm (118) and secured to the base assembly; an upper link positioned within the hollow arm (118) and secured to the display mount such that the display mount rotates around the upper axis of rotation in correspondence with a rotation of the upper link around said upper axis of rotation; an inner link positioned within the hollow arm (118) being rotatably secured by its lower end (1612) to the lower link and rotatably secured by its upper end (1616) to the upper link; and an outer link positioned within the hollow arm (118) being rotatably secured by its lower end (1612) to the lower link and rotatably secured by its upper end (1616) to the upper link. a base assembly including a processor and a crank shaft configured to define a lower axis of rotation (120); a display assembly including a display that is driven by the processor, the display secured by a display mount relative to a display shaft that is configured to define an upper axis of rotation (120); a hollow arm (118) secured to the crank shaft and forming an angle α with said base assembly, such that when the hollow arm rotates around the lower axis of rotation to adjust said angle α, the crankshaft rotates correspondingly, wherein said crankshaft comprises a crankpin such that reducing the α angle causes the crankpin to turn in a counterclockwise direction and this action forces a connecting rod coupled to the crankpin so that movement of the connecting rod compresses a spring that is arranged in the base assembly, and said hollow arm is secured to the display shaft such that when the hollow arm rotates around the upper axis of rotation the display shaft rotates correspondingly; a lower link positioned within the hollow arm (118) and secured to the base assembly; an upper link positioned within the hollow arm (118) and secured to the display mount such that the display mount rotates around the upper axis of rotation in correspondence with a rotation of the upper link around said upper axis of rotation; an inner link positioned within the hollow arm (118) being rotatably secured by its lower end (1612) to the lower link and rotatably secured by its upper end (1616) to the upper link; and an outer link positioned within the hollow arm (118) being rotatably secured by its lower end (1612) to the lower link and rotatably secured by its upper end (1616) to the upper link.
