Provided is a temperature controller for an industrial heating apparatus adjusting a soak time on the basis of the variation of the thermal energy. Accordingly, since a temperature equilibrium time point of the center is determined by reflecting a temperature tolerance in the chamber and a soak time is corrected and since the temperature equalization time point is set on the basis of a full load state in which the variation of the input thermal energy per time is the smallest, the temperature at the center falls within an allowable upper/lower limit range even if a partial load state is applied, whereby the temperature control apparatus and method for an industrial heater applicable regardless of the amount of heating targets may be provided.

The electric heating device includes the electric heating temperature control apparatus.

A circuit configuration is disclosed for use in an appliance includes a power switch configured to open and close a first group of electrical contacts, where the contacts while closed cause the appliance to energize upon a user initiating a use of the appliance. The circuit configuration also includes a primary timing device electrically connected to the first group of electrical contacts, the primary timing device being actuated upon energization of the appliance and the primary timing device being configured to de-energize the appliance after a first time period by opening the first group of electrical contacts. The circuit configuration also includes a secondary timing device electrically connected to the power switch by a second group of electrical contacts, where the secondary timing device is configured to de-energize the appliance after a second time period, where the second time period is set based on the first time period.

Provided is an aerosol generating device which is capable of optimizing the timing at which aerosol generation is stopped. This aerosol generating device 100 includes: a power source 114 which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor 106 which outputs a measurement value indicating a first physical quantity for controlling the power supplied; and a controller 130 which acquires the measurement value output by the sensor 106, stores a profile of the measurement value, and controls the supplied power by controlling a second physical quantity different to the first physical quantity, on the basis of the acquired measurement value and at least a part of the stored profile of the measurement value.

Provided is an aerosol generating device which is capable of stopping aerosol generation at an appropriate timing. This aerosol generating device includes a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a circuitry which controls the power supplied from the power source on the basis of the measurement value. The circuitry controls to increase a power supply amount per unit time in response to a first condition that the measured value is equal to or larger than a first threshold being satisfied, and to decrease the power supply amount per unit time in response to a second condition that the measured value is less than a second threshold greater than the first threshold and a third condition which is different from the first condition and the second condition being satisfied.

A modular heated surface system which can quickly be assembled from several pieces. The system can be designed to fit sidewalks and driveways of any size and includes durable surfaces for driving vehicles across the platforms. A drain assembly is included to ensure that the water produced from melted ice and snow is properly drained away from the heated surface. The system is powered by plugging the system into a standard 120V outlet.

Disclosed herein are aspects of portable vaporizers forming isolated vapor paths through vapor dispensers wherein a material chamber is part of a unitary furnace formed above a resistive heater and aliquots of heated air are drawn through plant-based material in the formed material chamber. A printed circuit board in signal communications with at least one temperature sensor controls the power flow to the resistance heater to select the temperature produced by heating elements in the furnace. A rechargeable battery power supply is mounted in a body to supply power the heating element.
