Abstract:
A method for RF dielectric heating an object (22) having a variable weight including a medium is provided. The method comprises: (A) placing the object having the variable weight including the medium (26) into an enclosure; (B) adding an ionic substance to the medium; (C) initiating a heating process by subjecting the medium including the object to a variable AC electrical field (24); and (D) controlling the heating process. The method further comprises using an air flow (30) having an ambient temperature (32), or being heated before getting into the enclosure, to carry away the evaporated medium from the enclosure.
Abstract:
A lateral RF MOS transistor with at least one conductive plug structure comprising: (1) a semiconductor material of a first conductivity type having a first dopant concentration and a top surface; (2) a conductive gate overlying and insulated from the top surface of the semiconductor material; (3) at least two enhanced drain drift regions of the second conductivity type; the first region laying partially underneath the gate; the second enhanced drain drift region contacting the first enhanced drain drift region; (4) a drain region of the second conductivity type contacting the second enhanced drain drift region; (5) a body region of said RF MOS transistor of the first conductivity type; (6) a source region of the second conductivity type; (7) a body contact region of the first conductivity type; and (8) a plug region further comprising at least one conductive plug region, and at least one between-conductive-plug region.
Abstract:
Heating an object, (food, wet clothing) having a variable weight that includes a medium (water) comprising: placing the object having the variable weight including medium into an enclosure; initiating a heating process by subjecting object with medium to a variable AC electrical field; and controlling the heating process. The object/clothing having a first "cool" state and therefore includes a maximum weight in the first "cool" state due to absorption of medium. The object is substantially free from the medium/water in a second "heated" state due to substantial evaporization of the medium from the object. Heating process is completed when the object is substantially transitioned into the second "heated" state. The method further comprises using an air flow having an ambient temperature inside the enclosure to carry away the evaporated medium from the enclosure.
Abstract:
A method for heating a medium that includes an object having a variable weight (184) is provided. The method comprises (A) placing medium including an object having variable weight (184) into a variable enclosure (182) having adjustable dimensions; (B) initiating a heating process by subjecting the medium including the object to a variable AC electrical field (172); (C) substantially continuously measuring (176) an impedance of medium including the object during the heating process; (D) adjusting dimensions of said variable enclosure to optimize the heating process; (E) adjusting parameters of the variable AC electrical field (174) to optimize the heating process; and (F) controlling (178) the heating process.
