Abstract: A method for minimizing or eliminating external interference signals in a CDMA mobile phone uses a memory for storing a plurality of predetermined control voltage values, received signal strength indicator (RSSI) data classified into various grades for each of the control voltage values, reference value data classified into various grades for each RSSI to meet a given signal receiving condition and control voltage change data corresponding to the reference value data. The method includes the steps of setting an initial control voltage to control a damping device, receiving a communication signal, finding one of the RSSI data grades where the RSSI of the received signal belongs, finding one of the reference value data grades where the received signal belongs, and evaluating the difference between the normal signal and external interference signals based on the control voltage, RSSI grade and reference value data grade.

Abstract: A multi-purpose cooking appliance comprising: a self-supporting base, a lid mountable on the base, a cooking chamber defined between the base and the lid, a heat conductive pan within the cooking chamber, a heat source connected to the heat conductive pan, removable, elongated skewers for supporting food within said cooking chamber, the skewers being formed of a heat conductive material and having a length sufficient to span the length of the conductive pan and rest thereon, and at least one tray including a surface engageable with a surface on said pan to locate the tray within the cooking chamber, the tray being dimensioned to be spaced from the pan.
