Controllable heated mask

A controllable heated mask comprising:

• a main body, the mask being shaped for covering at least part of a face of a user, said mask having areas, each area for contacting at least one of a forehead, eyebrows, nose, and cheeks;
• a plurality of electrodes, each electrode being retained in one said area and comprising a heating element;
• a heating element having a conductor section having a resistance in a preselected ratio to resistance of other conductor sections;
• a control module comprising a temperature selection circuit;
• said control module having a first set of terminals and a second set of terminals for providing power to said mask and a control circuit for selectively connecting said first set of conductors to a first power supply or to a second power supply respectively;
• said temperature selection circuit being coupled between said first set of terminals and said mask and said control circuit coupling said second set of terminals to said mask to provide a fixed temperature;
• a thermostat coupled to the temperature selection circuit, said temperature selection circuit being coupled to provide a setpoint to said thermostat;
• a temperature sensor coupled to provide an input to said thermostat indicative of temperature in said mask;
• wherein said first set of terminals comprises terminals for connection to a first power supply, the first power supply being energized by line current, and wherein said second set of terminals comprises a terminal structured for coupling to a USB power port, wherein the heating elements are selected with respect to a power level provided by said first power supply to provide heat at a therapeutic level and with respect to a power level provided by said second power supply to provide heat at a lower level when coupled to the USB power port;
• and
• wherein said control circuit comprises a switch for selectively coupling said second set of terminals to said heating element and bypassing said temperature selection circuit.
