Filed:

Dec 28, 2001

Appl. No.:

10/034177

Inventors:

Myoung Jun Lee - La Habra CA 90631

International Classification:

H05B 102

US Classification:

219505, 219212, 219497, 219548, 219552

Abstract:

A thermo-sensitive heater and heater driving circuit are disclosed. The thermo-sensitive heater comprises a cord-shaped nylon thermistor that surrounds a heating element, such that the thermistor detects the temperature of the heating element and controls the driving current for a heating coil. Also, the present invention includes electromagnetic shielding material, which is formed by winding an electric conductor around the outer surface of the nylon thermistor, or formed as a wire mesh. This shielding material is advantageous for discharging the electric field radiated from inside of the heater to an external electric field, thus safely eliminating harmful electric fields. Also, the present invention further provides a driving circuit for safely driving the heater, which includes a temperature controller or an overheating prevention circuit.

Inventors:

Myoung Jun Lee - La Habra CA, US

International Classification:

H05K 9/00

US Classification:

174377, 219212

Abstract:

The present invention relates to a system for protecting a person from electromagnetic waves. The system includes an electromagnetic-wave shielding blanket, an electric conductor housed in the electromagnetic-wave shielding blanket for absorbing electromagnetic waves and transferring the electromagnetic waves to a ground, and a grounding connection for connecting the electric conductor to the ground. The system further includes an electric heating mattress housing the ground, and an electric conductor housed in the electric heating mattress for absorbing electromagnetic waves and transferring the electromagnetic waves to the ground, wherein the grounding connection connects the electric conductor of the electromagnetic-wave shielding blanket to the electric conductor of the electric heating mattress.

International Classification:

H05B 3/06

US Classification:

219618, 219539, 219549

Abstract:

An electromagnet heating cable includes a center core, an inner layer body formed around the center core, an intermediate layer body formed around the inner layer body, an outer layer body formed around the intermediate layer body, an inner layer coil having a magnetic core disposed between the center core and inner layer body, an intermediate layer coil disposed between the inner layer body and the intermediate layer body, and an outer layer coil disposed between the intermediate layer body and outer layer body, wherein when a temperature of the heating cable exceeds a threshold, the intermediate layer body melts to electrically connect the intermediate layer coil to the outer layer coil.

US Classification:

219535

Abstract:

The present invention relates to an electric heating element. The electric heating element includes a core support, an inner wire wound around the core support, an intermediate dielectric layer formed around the inner wire, an outer wire wound around the intermediate dielectric layer, a connector connecting an end of the inner wire to an end of the outer wire, and an outer sheath formed around the outer wire, wherein the inner wire and outer wire are arranged to have opposite phases according to a direction of a current to attenuate magnetic fields generated from the inner wire and outer wire when a power is applied to the to inner wire and outer wire.

Inventors:

Myoung Jun Lee - La Habra CA, US

International Classification:

H05B 3/10

US Classification:

219548

Abstract:

The present invention relates to a magnetic field-blocking panel heater. The magnetic field-blocking panel heater includes a panel heating element comprising a heat generating electrical conductor enclosed in an electrical insulator and first electrodes for transferring current to the electrical conductor. A magnetic field-blocking material surrounds the panel heating element. Second electrodes are respectively connected to the first electrodes of the panel heating element and extended outside of the magnetic field-blocking material for transferring current to the first electrodes, wherein the magnetic field-blocking material absorbs a magnetic field generated by the panel heating element when current is applied to the electrical conductor via the first and second electrodes.
