A scent dispenser may comprise a vial retaining mechanism, a heating element, vial sensor, and a controller. The vial retaining mechanism includes a vial coupling that removeably retains a vial containing a scented solution. The includes a wick extending from a cavity of the vial through an opening of a neck of the vial. The heating element is shaped to receive and heat the wick of the vial. The vial sensor includes an array of sensor pads that are arranged in alignment with the vial retained by the vial coupling. The controller is electrically coupled to the heating element and electrically coupled to the array of sensor pads. The controller regulates a temperature level of the heating element, and receives signals from the array of sensor pads and processing the signals to determine a fluid level of the vial.

An electric stovetop includes a vitroceramic top part, an electric heating element built-in below the top part, and a bottom box with the electric heating element mounted through the bottom box. The electrical heating element can include parallel and equidistant tracks defining a rectangular heating area. Each track is divided into three segments, a large central part and two smaller end parts. Each track is positioned corresponding to a sliding button for controlling power to start heating and to control intensity of heat. The sliding button sets each track according to at least three stages of activation: no power, power to the central part, and power to the smaller ends. There can be an intermediate position defined by a midpoint with a tactile stop to indicate the transition from the second stage to the third stage.

A cooking vessel according to one example embodiment includes a food receptacle for holding food during cooking. The cooking vessel includes an inner shell and an outer shell. An outside surface of the inner shell forms the food receptacle. A portion of an inside surface of the inner shell is spaced from a portion of an inside surface of the outer shell forming a sealed volume between the inner shell and the outer shell. A heat pipe is positioned within the sealed volume between the inner shell and the outer shell for distributing heat through the sealed volume between the inner shell and the outer shell. Embodiments include those wherein each of the inner shell and the outer shell includes a respective bottom wall and a respective side wall.

A ceramic heater according to one aspect of the present invention has a cylindrical ceramic heater and an annular metal flange fitted around the ceramic heater. In the ceramic heater, one side of the flange with respect to an axial direction of the heater body is concave in the axial direction to define a concave part. The concave part includes a glass accumulation region filled with a glass material. The glass material in the glass accumulation is fused to the flange and to the heater body.

A vaporizer device is described in which a first air pathway extends from an inlet to a heating element. The heating element is configured to heat air from the first air pathway to produce heated air. A second air pathway extends from the heating element to a mouthpiece and is configured to carry the heated air. The first air pathway is configured to bring the air into thermal contact with at least one component in the second air pathway which absorbs heat from the heated air to heat air in the first air pathway and thereby reduce the energy needed to heat the air.

A high-voltage ceramic electric heating element, comprising a body (9), the body (9) being hollow and having an open trailing portion, and a notch (7) being provided on the body (9) in the axial direction and extending through from left to right; a temperature control region (8) is provided at a position on an outer resistance layer (2) of the body (9), and the cross sectional area of the temperature control region (8) is smaller than the cross sectional area of the body (9). Using the high-voltage ceramic electric heating element can improve the ignition reliability and the service life.

The present disclosure is directed to a method for forming a cured composite component. The method includes laying one or more layers of uncured composite material onto a conductive core. An electric current is supplied to the conductive core to resistively heat the one or more layers of uncured composite material to a temperature sufficient to cure the one or more layers of uncured composite material into the cured composite component.

An aerosol-generating system includes a liquid-storage portion configured to hold a liquid aerosol-forming substrate, a first electrode, a second electrode, and a control system. The second electrode is spaced from the first electrode. At least a portion of the liquid storage portion is arranged between the first electrode and the second electrode. The control system is configured to measure an electrical quantity between the first electrode and the second electrode, and detect a draw on the aerosol-generating system based on the measured electrical quantity information.

A window for resistive heating and a camera apparatus including a window for resistive heating.
