    Abstract: Method and system for monitoring the operation of a stamping press preferably for forming automobile parts, such as fenders and quarter panels, based on a plurality of features extracted from a press signature. The method includes defining the plurality of features, each feature representing a parameter associated with the process of forming the parts, and operating the stamping press so as to produce a predetermined number of production parts while collecting a production operating signature. The method also includes extracting the feature values from the production operating signature to obtain production feature values, and comparing the production feature values to predetermined operating limits which represent limits within which acceptable parts are formed. Two feature values of particular interest are sheet metal blank thickness and hardening coefficient of the sheet metal which are estimated from data obtained from at least two punch locations.

    Abstract: A vehicle security system, comprises a coded key (10), a reader (12) for reading the code of the key (10) and generating an encoded electrical signal, a data transfer bus (14) connected to the reader, and a plurality of units (16, 18, 20) connected to the data transfer bus (14) and rendered operative only upon receipt of a predetermined valid code from the reader. Each unit (16, 18, 20) is arranged upon receiving an invalid code to transmit an error code over the data transfer bus (14) to the reader (12) or to other units connected to the bus, and upon detection of an error code on the bus from at least selected ones of the units (16, 18, 20), other units (16, 18, 20) connected to the bus are rendered inoperative even if the latter units had received valid codes.

    Abstract: Method of and system for monitoring the operation of a stamping press including a punch and a die for forming parts from a blank based on processed punch tonnages measurements at predetermined locations in the working stroke. The method includes selecting at least two punch locations at which a press variable measurement will be made and operating the stamping press so as to produce production parts to measure a production press operating variable at the locations for each production part produced. The method also includes processing the production press operating variables to obtain production operating parameters and comparing the production operating parameters to predetermined operating limits representing limits within which the variation in blank thickness and work hardening coefficient of the sheet metal are in control and acceptable stampings are being produced.
