An automatic controlled electric heating device (1) for the production of stamped parts, by tool hardening from hot stamping of the material with specific raw material, granting greater hardness and mechanical resistance to the part, which allows the creation of lighter end products which support greater loads and impacts, consisting basically of the following parts: heating controller system (2), power controller system (3), power transformer (4), data acquisition system (5), mechanical fastening device (6) of the plate (P) and performance of electrical contact and expansion compensation system (7).

The invention relates to an electrical device for melting snow and ice that has accumulated on the surface of a. vehicle. During inclement weather, snow, sleet, rain or hail accumulate on all exposed surfaces of the automobile, in particular on the flat surfaces, such as on the roof the hood, the trunk, or a truck bed of a vehicle. These areas of snow coverage are relatively large and significantly high off the ground, presenting a challenge to clean in terms of time and effort. Frequently, the owners of the vehicles need to use their automobiles early in the morning, when snow or ice that has accumulated over night is at its hardest. Since it is unsafe, and sometimes unlawful, to operate a vehicle that has not been properly snow dusted and deiced, cleaning must be effectuated before a vehicle can be driven on the roads.

Systems and methods for heater assemblies are described herein. A gas chromatography device can include a heater assembly. The heater assembly can include a plate. The plate can have an inner diameter, an outer diameter, a planar surface, and a curved surface. The heater assembly can include a wire. The wire can form a plurality of coils around the inner diameter and the outer diameter of the plate. Each of the plurality of coils can have a diameter greater than half of a difference between the outer diameter of the plate and the inner diameter of the plate. Each of the plurality of coils can be configured to intersect the inner diameter of the plate and the outer diameter of the plate. An aspect ratio of half of the difference between the outer diameter of the plate and the inner diameter of the plate to a thickness of the plate is greater than 1. The device can include a mounting piece configured to couple with the heater assembly.
