Disclosed is a method and system enabling the electronic dissemination of electronic coupons combined with both coupon-related and coupon-unrelated information stored on a computer readable storage medium, and a control program limiting a user’s access to only such coupons as have been authorized through user input of an access code. According to a feature of the present invention, the method comprises the steps of determining spectral information relevant to the sequence of images, and utilizing the spectral information to classify a pixel as one of background, shadow and object. The at least one test sample and the at least one compensation sample are selectable and presentable in combination such that an average exposure interpreted by the camera is substantially the same for each of the plurality of brightness measurements. The method also comprises coupling pins to the first and second sets of wires. , in the form of thermoplastic particles enmeshed within a fibril matrix. During this step the protective layer is penetrated to open a via to the surface of the semiconductor material.
