Embodiments include a balance mechanism having a first cam and a second cam configured to convert a variable force exerted by the energy storage member into a substantially constant force applied to a mounting portion. The balance mechanism may be useful for balancing forces such that a user can set the height of an electronic display and/or other equipment attached to the balance mechanism at a number of heights within the range of travel allowed by the mechanism. Lift mechanisms, display positioning apparatuses, and height adjustable desks incorporating a multi-cam balance mechanism are also provided. A method of positioning a display is also provided.

A smart lectern system is provided. The smart lectern system comprises a smart lectern comprising a base, a mast extending from the base and a touchscreen panel attached to the mast wherein the touchscreen panel generates a touch communication. A hub is provided wherein the hub receives the touch communication and transmits a touch command to an output driver.

An apparatus drives and guides movement of a display assembly that includes a display unit. At least one track extends along at least one side of the display assembly and defines a path along which the display assembly is driven. A plurality of pins extend from the display assembly to the at least one track. At least one constant force spring has at one end a coiled part that is rotatably coupled to the display assembly, and an opposing end fastened to a fixed mounting location, and an uncoiled part extending between the coiled part and the opposing end. The at least one constant force spring is configured to drive the display assembly from a lowered position to a raised position while the plurality of pins travels along the at least one track and guide movement of the display assembly.
