A micro-power generator is integrated in a pneumatic valve controller, such that the micro-power generator is powered by the same compressed air supply used to operate the valve. In accordance with one aspect of the present invention, a method for detecting a trace identifier mismatch using a detection system with a hardware component and a software component includes detecting a change in trace information associated with the path using the hardware component. A first rule set is selected from among multiple rule sets assigned to a respective one of multiple applications, based on the first rule set being assigned to the first application. The read-image processing unit searches the read image of the document for the image of the additional object and performs the processing associated with the additional object image on the information obtained from the extract area specified by the additional object image. For example, to predict the pixel values for a block of pixels, a video encoder or decoder uses spatial extrapolation from the pixel values of pixels in a causal neighborhood for the block of pixels. The metadata is executed by the TV to establish the settings, which consequently may be optimized for the particular video stream.
