A cooking apparatus includes a body provided in a top thereof with an opening, at least one heating unit arranged on both sides of the body, a grill unit mounted on a top of the body, and a heat reflecting unit arranged toward the heating units below the opening of the body. Further, embodiments of the present invention provide systems and methods for increased gain profile accuracy, including methods and systems to reduce the effects of temperature andor process variations on the gain profile of an amplifier. Then, the apparatus obtains the magnetic pole position correction quantity based on a predetermined operation expression using the d-axis voltage command value and the q-axis voltage command value from the dq vector control process. In operation, the detection and switch circuitry receives a signal transmission from the secondary audio source and determines whether the signal received is desirable. Methods of installation of the raceway are applicable to new construction and retro-fitting existing structures, including drainage systems, bridge structures and other outdoor enclosures, and may be used with many types of roofing materials including asphalt, wood and metal.
