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.

A heating wire control system has a normally open relay, a control circuit, and a remote controller. The control circuit has a transmitter/receiver adapted for wireless communication with a remote server and is adapted to obtain operational parameters from the remote controller through the server, and to use the operational parameters to selectively provide an electrical signal close the relay and energize heating wire. Weather forecasts, time, ambient conditions, and manual input are all selectively used by the control circuit to operate the control system.

A one-piece heater rack includes a number of arrays of attachment nodes and a surrounding peripheral structure. The attachment nodes are configured to allow the attachment of ceramic supports, the ceramic supports designed to hold open type coil electrical resistance heating elements that make up of a heater assembly using the heater rack. The attachment nodes allow attachment of the ceramic supports from above and below the heater rack for ease of installation. The heater rack also includes other features that providing mounting support for other heater assembly elements like terminals, thermostats, temperature limit switches, and air flow control over and through the heater using the peripheral structure, the arrays of attachment nodes or combinations thereof.

A system for heating and cooling a room including a layer of channels and a heating layer. The layer of channels allows a chilled fluid to pass through it while the heating layer has a resistor that is configured to turn electricity into heat.

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.

Examples provide a heated portal frame associated with an order dispensation portal for dispensing a set of items to a user. The heated portal frame includes a metallic framework forming a horizontal surface defining at least one tote access portal. Each tote access portal defined by the metallic framework is associated with a recessed tote compartment configured to support at least one tote storing a set of item beneath the metallic framework. The heated portal frame includes a set of resistance heating elements associated with at least a portion of the portal frame. The resistance heating element(s) warm the frame to increase a temperature of an exterior surface of the portal frame in contact with ambient exterior air. The heating element(s) can be located beneath the frame or embedded within the frame to prevent condensation forming on the portal frame.

An improved comfort control system for controlling an environment regulation system includes a processing unit, a video interface, an input subsystem, a hierarchy of switching mechanisms and a special computer program. The hierarchy of switching mechanisms includes an electronic switching mechanism having a jumper and a second tier switching mechanism implemented by the special computer program and including a key combination. When the control device is in an operation mode and the jumper is in an enabled position, entering the key combination causes the special computer program to switch the comfort control system to the configuration mode. When the comfort control system is in an operation mode and the jumper is in a disabled position, the special computer program does not switch the control device to the configuration mode from the operation mode.

A heated floor panel for an airborne vehicle and an airborne vehicle having at least one heated floor panel are described. The floor panel includes a controller housing, a first heated panel configured to heat the floor panel, a panel connector arranged in a wall of the controller housing, at least one power line coupled between the panel connector and the first heated panel and configured to supply electric power, which is input to the panel connector, to the first heated panel, a switch connected in one of the power lines, and a microcontroller connected to the switch and configured to actuate the switch for interrupting the electric power supply to the first heated panel in case of an electric fault in the floor panel.

A snow melting assembly for a driveway includes a controller that comprises a microprocessor and a receiver. The receiver is operationally coupled to the microprocessor. A cable is coupled to and extends from the controller. A first mat is coupled to the cable distal from the controller. The first mat comprises rubber so that the first mat is resiliently compressible and rollable. A first heating element is embedded in the first mat. The first heating element is operationally coupled to the cable. A power cord is coupled to and extends from the controller. The power cord is configured to couple the controller to a source of electrical current. Programming code is positioned on an electronic device that enables a user to wirelessly communicate with the microprocessor, via the receiver, to signal the microprocessor to actuate the first heating element to melt the snow that is positioned on the first mat.
