A kitchen appliance for processing food, and in particular for producing blended beverages is provided. By being manipulated by the user, an editing device links some of function programs stored in the function blocks in the library to form a control program which controls the exchange of signals between IO modules and external devices. A secondary transmit power and a secondary transport block size for a secondary stream may also be determined. The disengaging member may be, for example, a spring or the like. The sensing circuit and analog-to-digital converter generate digital code based on the difference between the reset voltage and the summed offset and pixel signal voltage.
