An infrared energy supply system is disclosed including an infrared (IR) energy emitter device including a heat dissipating housing including an internal cavity that houses an IR bulb, an interior reflection unit and a cooling fan, an outer reflection unit coupled to the heat dissipating housing that includes a curved reflection component extending outwardly from the heat dissipating housing and side reflection components that extend outward from the heat dissipating on opposite sides of the curved reflection component, and a guide rail disposed on both sides of the outer reflection unit. The infrared energy supply system further includes a control unit coupled to the infrared energy emitter device via a coupling device. In some instances, the internal cavity houses multiple IR bulbs where emitted IR rays reflect off of the interior reflection unit and the curved reflection component to culminate at a first focal point and a second focal point.

A humidifier for a respiratory assistance device, is provided wherein at least a portion of an inside of a chamber is exposed to light such that light impinges on a metallic or carbon-based material to generate localized heating of liquid molecules around the metallic or carbon-based material and generate vapour for use by the respiratory assistance device. A respiratory assistance device comprising a humidifier and related methods and apparatus are also provided. Arrangements are provided for generating vapour by impinging light on metallic and/or carbon based material, particularly in the form of nanoparticles.

A heating device with a contactless temperature control includes a temperature sensor for sensing a surface temperature of an object, a control circuit connected to the temperature sensor, and a heating unit coupled to the control circuit. The control circuit controls the heating unit to generate thermal energy based on the surface temperature sensed by the temperature sensor. A more comfortable and safer environment can be provided by instantly sensing the surface temperature of a user's body and simultaneously controlling the heating unit to generate thermal energy. Moreover, the device can prevent the overheating, which may cause the secondary damage of the user. Besides, the device can also prevent the poor efficiency caused by the insufficient heating.

The utility model discloses a novel crystal salt aroma stove which comprises an aroma stove body, a base and a built-in circuit control system. There is the aroma stove body, a cover, an aromatherapy oil placing groove, a protective screen, the base, a threading hole, a glass cover, a crystal salt placing groove, a heating bulb and a glass cover installing groove. The built-in circuit control system is arranged in the base of the aroma stove body. A power supply module and a light control module are arranged on the built-in circuit control system. The novel crystal salt aroma stove is reasonable in design, attractive in appearance, simple and elegant, has an effect of air purification through crystal salt besides a function of aromatherapy and air beautification which an existing aroma stove can only perform, and enables users to breathe pure air, experience aesthetic sentiments, relax tense nerves and return to simple nature.

In one embodiment, the present invention includes an apparatus to heat a body. The apparatus includes a first and second heating element. The first heating element has a first conductive path and is coupled to pass a current. The second heating element has a second conductive path that runs adjacent to the first conductive path. The second heating element terminates an electric field produced within the first heating element. The first conductive path is coupled to redirect the current to the second conductive path and set up complimentary magnetic fields between the first and second heating elements.

A far infrared (FIR) sauna cabin equipped with a far infrared (FIR) heating elements constructed of ceramic, carbon, and/or light emitting diodes (LED), designed for therapeutic use in a sauna, capable of emitting far infrared energy, and heating an individual's skin for purposes of rejuvenation, anti-aging, weight loss, and acne therapy. The FIR heating element emits IR energy in a wavelength and frequency optimum for resonant absorption by the human body, resulting in the release of toxins stored within subcutaneous fatty deposits, which are then carried out of the person's system as he or she sweats. The FIR sauna is operated by a system comprising a local control system and a remote computer running access control software. A user account is configured containing a user's allowed privileges. When a user swipes an access card, the remote computer verifies the requested privilege. If allowed, the local system energizes the sauna system.
