A heating system comprises at least one IR heating device 3 and at least one optical element arranged to focus or direct IR radiation emitted by the IR heating device 3 onto an object to be heated 1.

Radiant furniture made of a concrete mix includes one or more heating elements or hot water supplied hydronic tubing that provide comfortable radiant heat. Tabletops can be heated to a temperature that is comfortable for people seated at the table. Other tabletops can be heated to a lower temperature for use in a greenhouse. Benches and seats can be heated to provide comfortable heated seating. A heated surface in the radiant furniture includes a conductive heating element that has a plurality of non-overlapping runs, with a density of the heating element runs being greater near the edges than at an interior part of the heated surface. A controller senses the temperature of the furniture and the ambient temperature, then applies power to one or more heating elements in the furniture according to programmed temperature thresholds to provide comfortable radiant heat from the furniture.

A camping tent heating assembly for keeping campers warm in a camping tent includes a camping tent that has a floor. A heating pad is positionable beneath the floor of the camping tent such that the heating pad is in thermal communication with the floor. The heating pad heats the floor when the heating pad is turned on to warm campers that are sleeping in the camping tent. A connection box is coupled to the heating pad and the connection box is in electrical communication with the heating pad. A control unit is in electrical communication with the connection box for turning the heating pad on and off. The control unit has a heat adjustment control to adjust a temperature of the heating pad between a minimum temperature and a maximum temperature.

Systems and methods are provided for controlling infrared radiation (IR) sources of a sauna including tuning IR wavelength-ranges and radiated power-levels of IR sources, and directing IR to locations on a user's body. In one illustrative embodiment, a sauna may be provided having adjustable IR emitters to emit IR at any wavelength resulting in a desirable radiation treatment for the sauna user. In another illustrative embodiment, a method is provided for tuning IR emitters in a sauna.

An electric heating device includes a conductive pipe having an interior and at least one end portion, one or more heating elements disposed in the conductive pipe, one or more power connectors extending into the interior of the conductive pipe to be electrically connected to the one or more heating elements, a ground connector contacting the at least one end portion of the conductive pipe to be electrically connected to the conductive pipe, and a first member enclosing the at least one end portion of the conductive pipe, the one or more power connectors, and the ground connector.

A floor panel assembly includes an insulating layer which protects a sheet heater, first and second structural layers, and a honeycomb layer for support. The floor panel assembly allows for heating of the cabin of an aircraft without mechanical damage to the sheet heater.

A heating system including a carbon veil heating element having at least two busbars embedded between opposite layers of insulating film, a connector busbar assembly having at least two connector electrical busbars and a matrix of insulation connecting them, penetrating conductive fasteners configured to protrude through the respective busbars of the heating element and the connector busbar assembly, and a controller configured to connect to the connector busbars and apply electrical current sufficient to cause the heating element to produce heat between the veil busbars. The busbars preferably have a width to thickness ratio greater than 10, more preferably greater than 100. Methods for installing the heating system are also described.

The invention concerns a window including a window pane with one or more glass panes, a window frame in which the window pane is provided, at least one temperature sensor arranged in or at the periphery of the window pane, and an electric circuit connected to the temperature sensor mounted on or in the window frame. The electric circuit is configured to be connected to an operation unit which is configured to regulate the incident light through the window pane. The invention furthermore concerns a method for controlling a window wherein the electric circuit controls the means configured to regulate the incident light through the window pane based on a set of parameters. The parameters are determined on the basis of the orientation and geographical position of the window whereby the supply of free energy is optimized and the amount of energy supplied from energy sources in the room is reduced. In an embodiment the window can be controlled by means of an application configured to run on a mobile communication unit.

In the method for increasing the availability of an elevator standing unused at a landing the ambient temperature of at least one electrical device of the elevator is measured; and when the ambient temperature falls below a threshold value, electric current is conducted to at least one electrical device of the elevator for warming the electrical device in question. The patent application also includes an independent claim for a system for increasing the availability of an elevator standing unused at a landing.
