A display device and an electronic device are provided. The display device includes a backlight module and a display panel which are stacked. The backlight module includes a back plate, at least one near-infrared light-emitting element, and at least one diffuser. The back plate includes a bottom plate and multiple side plates. The multiple side plates encircle and are connected to the bottom plate to form a receiving space. The at least one near-infrared light-emitting element is disposed in the receiving space. Each of the at least one near-infrared light-emitting element is disposed corresponding to one side plate. The near-infrared light-emitting element is inclined relative to the display panel, and configured to emit near-infrared light that can heat the skin of a user. The diffuser is disposed corresponding to a light-exiting surface of the near-infrared light-emitting element and configured to diffuse the near-infrared light emitted by the near-infrared light-emitting element.

A heating element can be moved by a machine, such as a machine including a fan, an actuator, or a conveyor. The heating element can be attached to or embedded in a fan or an actuator. Or, the heating element can be attached to or embedded in a conveyor belt of a conveyor. A combination of a heating element and a mover machine can be further combined with a heat radiating wall. The heating element and the machine can be arranged behind the wall. And, when the heating element and the machine are powered on, the heating element converts electrical energy into heat, which increases the temperature of the wall, and the machine moves the heating element to be next to different areas of the wall. This allows for heat to be distributed more evenly to the wall than it would be if the heating element did not move.

A refrigeration heating assembly and method of operation are generally provided herein. The heating assembly may include an inner glass tube, a resistive heating element, an outer glass tube, a first end cap, a second end cap, and a sensor assembly. The inner glass tube may include a continuous inner wall defining a central passage. The resistive heating element may be disposed within the central passage. The outer glass tube may include a continuous outer wall disposed about the inner glass tube. A radial gap may be defined between the glass tubes. The first end cap may be positioned on the outer glass tube and the inner glass tube at a first end. The second end cap may be positioned on the outer glass tube and the inner glass tube at a second end. The sensor assembly may be disposed in fluid communication with the radial gap.

A surface heater including a substrate, an insulating layer positioned on the substrate, and a heater layer positioned on the insulating layer, wherein the insulating layer and the heating layer are co-fired.

The present disclosure relates to a camera module, and a dew condensation prevention system of the camera module, and there is disclosed a camera module including a lens assembly; a lens barrel in a cylindrical shape with a predetermined height configured to accommodate the lens assembly; and a heat radiation member formed along an outer surface of the lens barrel to transfer heat to an outermost lens of the lens assembly, wherein the lens assembly has a field-of-view region formed in a first direction and a second direction crossed with the first direction, and at least one of the first and the second field of view is above 180 degrees, and a dew condensation prevention system using the same.

A feeding fluid warming system broadly includes a liner bag and an ultraviolet light warming device. The liner bag includes an inner bag that receives feeding fluid therein and an outer bag that holds warming fluid therein. The warming device includes a container, an ultraviolet light source, a temperature sensor, and a controller. The container receives the liner bag therein and the ultraviolet light source heats the warming fluid, which in turn heats the feeding fluid to temperatures within a thermal neutral zone so as to effectively and consistently maintains the fluids at these temperatures in addition to sterilizing the warming fluid.

In one example, an article is provided for use with an apparatus for generating an aerosol using an irradiative light source. The article has smokable material in combination with a transparent window through which light can pass. In another example, apparatus for generating an aerosol has an irradiative light source located in the apparatus. At least one optical component manipulates light emitted in use by the irradiative light source. A receptacle accommodates smokable material and receives light emitted in use by the irradiative light source. A transparent window is arranged between the receptacle and the at least one optical component. A combination of an apparatus for generating an aerosol and an article is also disclosed.

The present invention discloses a heat radiator, especially an infrared radiator, having at least one radiation source by means of which supplied electrical energy is convertible into heat radiation, as well as a control. This control comprises at least one frequency converter having a first, a second and a third output so that between the first and the third output a first alternating current is providable and between the second and the third output a second alternating current is providable by means of which the at least one radiation source is operable.
