The present invention is a method for calibrating the temperature of a cooking appliance. The upper shield layer includes a first portion at least part of which covers a top surface of the magnetic field detecting element, and a second portion that covers the first portion, and, the first portion has a larger absolute value of magnetostriction than the second portion. Each core is also configured to receive a corresponding value from each other core sharing the applicable resource, and to calculate a composite value compatible with the minimal needs of each core sharing the applicable resource. The duplex clip also has a projecting member extending from the rear surface and toward the front surface. A ranking of the search result is changed based on the users of the online forum comprising the one or more social contacts. These calculated energies are stored in an associated array.
