1. A method for controlling the operation of an adjustable work station having separately movable front and rear height-adjustable support surfaces which are respectively adapted to support thereon a keyboard and an associated information display screen, said method comprising the steps of:

  • providing a power-driven adjustment means for permitting independent height adjustment of the front and rear work surfaces and an automatic height adjustment control means for controlling the adjustment means and automatically adjusting the height of said front end rear support surfaces, including a timer means for measuring elapsed time and indicating that a predetermined amount of time has elapsed;

    adjusting in response to a user input the respective heights of said front and rear support surfaces by said power-driven adjustment means to a desired relative height arrangement wherein said front support surface is disposed at a first height and said rear support surface is disposed at a second height, determining first and second height values which represent said first and second heights, recording in said control means said first and second height values, and repeating said steps of adjusting, determining, and recording in order to (1) define a plurality of desired relative height arrangements and (2) produce a corresponding record of said relative height arrangements in the form of a plurality of relative height arrangement entries which are each defined by a pair of said first and second height values;

    selecting in response to a user input a first of said pairs of first and second height values and assigning a first time period thereto, and selecting in response to a user input a second of said pairs of first and second height values and assigning a second time period thereto;

    actuating in response to a user input said automatic height adjustment control means to effect automatic and sequential execution of the following steps in the following order;

    adjusting said rear support surface to the second height associated with said first pair of first and second height values, substantially immediately thereafter adjusting said front support surface to the first height associated with said first pair of first and second height values, thereafter maintaining said front and rear support surfaces at said last-mentioned heights for said first time period associated with said first pair of first and second height values, and thereafter indicating that said first time period has elapsed; and

    thenactuating said automatic height adjustment control means to effect automatic and sequential execution of the following steps in the following order;

    adjusting said rear support surface to the second height associated with said second pair of first and second height values, substantially immediately thereafter adjusting said front support surface to the first height associated with said second pair of first and second height values, and thereafter maintaining said front and rear support surfaces at said last-mentioned heights for said second time period associated with said second pair of first and second height values.
