Abstract: An automatic elevation-adjusting system includes an elevating unit, a control panel, a setting module, a calculating module and a central control module. The control panel includes a power icon, a direction icon unit, a setting icon, and a mode icon unit. The setting icon is operable to actuate the setting module to allow a user to press the direction icon unit and the power icon to enter data including a name, height, sex and age. The calculating module calculates average elevations for playing games, writing, reading and standing based on the user's sex and age, a pre-set specification of the table and an average height corresponding to the user's sex and age. The central control module actuates the elevating unit to move a table to the average elevation for playing games, writing, reading or standing when the game, writing, reading or standing icon of the mode icon unit is pressed.

Abstract: A multi-task table includes at least one board and an apparatus for adjusting the elevation and angle of the board. The apparatus includes an elevating unit, a tilting unit, a control panel, a setting module, a calculating module and a central control module. The elevating unit is used to move the board. The tilting unit is used to tilt the board. The control panel is used to show data about a user. The setting module is used to receive and store the data via the control panel. The calculating module is used to calculate values of elevation and angle of the board suitable for playing games, writing, reading and stand. The central control module is used to control the elevating unit, the tilting unit, the control panel, the setting module and the calculating module.
