Abstract
A method of controlling an apparatus with a control signal responsive to a feedback signal comprises: detecting when a feedback signal is not being received; determining whether a control signal is being provided; and adjusting the control to the apparatus depending on whether the control signal is being provided. An apparatus for performing this method comprises a programmed computer and a control signal feedback circuit for providing to the programmed computer a signal indicating whether a valid control signal is being provided.
