Abstract
A method of controlling a motorized device comprises the steps of providing a motorized device, receiving a code, checking that code, and changing the operational state of a portion of the motorized device in response to the code in certain circumstances. In one embodiment, the motorized device comprises a drive system, an activation mechanism, and a safety circuit that is in communication with the activation mechanism and at least a portion of the drive system. After receiving an unlocking code from the activation mechanism, the next step is to determine if the received unlocking code corresponds to a predetermined unlocking code. Subsequently, if the received unlocking code corresponds to the predetermined unlocking code, then the safety circuit is transitioned from a locked state to a normal operation state. Additional codes and corresponding operational states may also be incorporated into other embodiments of the method.
