Abstract
A microwave oven having four small holes in the floor of the cavity so that weight of food bodies within the cavity can be coupled by four nonconductive support columns protruding through the holes to a scale below the cavity. The scale may provide an analog signal which is a function of the weight. The signal may be converted to a digital input for a microprocessor which calculates the heating time for that weight over an input temperature range.
