Abstract
Abstract A warning system for installation in a vehicle, the system including a transducer located at a selected location in the vehicle to detect conditions existing at the location and to generate a signal containing raw information, a master unit connected to the transducer and an indicator connected to the master unit. The master unit includes means for removing extraneous information from the raw information in the signal generated by the transducer and thereby producing a remaining signal for use by the operator of the vehicle.
