Abstract: Disclosed herein are embodiments of a training lab that can be used as a teaching platform for individuals to learn electronic maintenance, such as transformer maintenance. The training lab can be either stationary or mobile, or can switch between the two modes. Modified transformers, or other equipment, can be incorporated into the lab to improve training.

Abstract: A system and methods for controlling adjustable furniture 60. The adjustable furniture 60 may be controlled by a control unit 34 in communication with a remote controller 40. A user may input commands to the remote controller 40 through a manual input device 42 or a microphone 43. The control unit 34 may be operable to adjust at least one actuable device element 28a-d, 32a-d, 52a, 52b in response to the commands. The adjustments of actuable device elements 28a-d, 32a-d, 52a, 52b may be measured by a sensor 58 that generates a sensor signal operable to be analyzed by the control unit 34 to determine an execution status of the command. The execution status may be indicated on the remote controller 40 by a speaker 44 or a display 45. The control unit 34 may also be operable to send signals for the remote controller 40 to make a noise.
