17. A touch sensitive control system for controlling a device, said control system comprising:
-
an interface comprising at least one predefined primary touch sensitive area and a contaminant detection area adjacent said activation area; and
a controller electrically connected to said interface and operatively responsive to said interface when said primary touch sensitive area is activated and when said contaminant detection area is not activated, said controller programmed to prevent actuation of the device when said contaminant detection area is activated, regardless of the state of said primary activation area. - View Dependent Claims (18, 19, 20, 21, 22, 23)
