A portable, personal therapy chamber for provision of radiation therapy. The therapy chamber includes a pair of telescopically positionable units that are lightweight and easily portable by a single user. The therapy chamber is configured for use by a single person lying generally prone on a surface. The units are formed from a plurality of pivotably coupled panels that are foldable in a first direction to a rolled up, tube-like storage configuration and unfoldable in a second direction to an arched formation or use configuration. The units, in the use configuration, are disposed to overlie the user and include a plurality of emitters that direct infrared energy toward the user's body.

In one embodiment, the present invention includes an apparatus to heat a body. A first conductive path and/or a second conductive path include a resistive heating element that produces heat from said current. The first conductive path is coupled to redirect the current to the second conductive path and set up complementapy magnetic fields between said first and second layers. A third layer substantially blocks an electric field produced from the resistive heating element included in the first layer and/or second layer.

A heating element for a sauna comprising an infrared heating element and a water filter for filtering out the far and mid infrared frequencies.

Devices and method for warm gas therapy is provided. Device comprises a gas warmer assembly to warm a first gas to a temperature in a first temperature range to obtain warm first gas. The device comprises a first delivery unit that can deliver the warm first gas to a main treatment chamber which encloses a sub-treatment chamber to retain heat therein. A second delivery unit can receive a therapeutic gas from a gas supply. The second delivery unit comprises a first portion and a second portion. The first portion substantially passes through the first delivery unit and therapeutic gas in the first portion is warmed by the warm first gas. The second portion delivers the warm therapeutic gas to a sub-treatment chamber. The sub-treatment chamber encloses a body part of a patient.

The present disclosure provides systems and methods that leverage neural networks for high resolution image segmentation. A computing system can include a processor, a machine-learned image segmentation model comprising a semantic segmentation neural network and an edge refinement neural network, and at least one tangible, non-transitory computer readable medium that stores instructions that cause the processor to perform operations. The operations can include obtaining an image, inputting the image into the semantic segmentation neural network, receiving, as an output of the semantic segmentation neural network, a semantic segmentation mask, inputting at least a portion of the image and at least a portion of the semantic segmentation mask into the edge refinement neural network, and receiving, as an output of the edge refinement neural network, the refined semantic segmentation mask.

A powder metallurgical molding forms an interconnector or an end plate for an electrochemical cell. The molding has a chromium content of at least 80% by weight, a basic shape of a plate and one or more flow fields with structuring formed on one or both of the main faces of the molding. A ratio of a maximum diameter D.sub.max of the molding, measured along the main face, to a minimum thickness d.sub.min of a core region of the molding which extends along the flow field or fields and is not affected by the structuring lies in a range of 140D.sub.max/d.sub.min350.

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.

The heating system for a sauna comprises an oven and an accumulator. The heating system is electrically connectable to a mains which provides a first electrical power. The accumulator is provided to provide a second electrical power. The oven is operable with the first and second electrical powers to increase the thermal power.

Sauna heaters are used to generate heat for saunas. Sauna heaters include a first halogen tube configured to generate heat, a second halogen tube configured to generate heat, wherein the first halogen tube is implemented a distance from the second halogen, and wherein the distance between the first halogen tube and the second halogen tube is configurable to adjust an amount of electromagnetic field (EMF) emitted by the heater. Sauna heaters also include a source of alternating current electrically coupled to the first halogen tube and the second halogen tube such that the source of alternating current is configured to provide the first halogen tube and the second halogen tube with a current, wherein the current powering the first halogen tube is out of phase with the current powering the second halogen tube.

A method, in which a fan equipped stove of a sauna is controlled automatically between an idle mode and a sauna bathing mode of the heating of the stove based on relative air humidity of the sauna; sound measured from the sauna; a measured load on benches of the sauna; a motion sensing signal measured from the sauna and/or the temperature of the stove. A controller, a stove and a sauna using the method are also described.
