View Edit Delete	US7230213A1	As indicated in the background above, the modular heated cover 200 may provide a solution to the problem of accumulated snow, ice, and frost or frozen work surfaces in various construction, residential, industrial, manufacturing, maintenance, agriculture, and service fields.	96	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	In an embodiment such as that illustrated in FIG. 9, the graphite 910 may be about 9 inches wide and 5 thousandths of an inch thick with a separating distance 818 for lengths 816 of about ¾ of an inch. Consequently, the resistance for the whole cover 900 may come to about 19 ohms. The cover 900 is designed to connect to a 120 volt circuit. With a drop in resistance of about 0.5 ohms as the graphite elements 904 heat up, the resulting current draw gradually moves from about 6.3 Amps (120 volts/19 ohms=6.3 Amps when first connected to the power source) to about 6.5 Amps (120 volts/18.5 ohms=6.5 Amps when maximum temperature is reached).	95	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	In the embodiment of FIG. 9, the pattern 914 may result in graphite lengths 916 that run vertically. Advantageously, vertical lengths 916 that run parallel to each other add to the structural rigidity of the cover 900. Consequently, the cover 900 is less susceptible to being blown back on itself due to wind. As a result a consistent and even heating of the area under the cover 900 is provided.	94	Added by DJM 2 2021	2/22/21, 12:00 AM

View Edit Delete	US7230213A1	In certain embodiments, the electrical power source 110 may be a power outlet connected to a 120V or 240 V AC power line. Alternatively, the power source 110 may be an electricity generator. In certain embodiments, the 120V power line may supply a range of current between about 15 A and about 50 A of electrical current to the thermal cover 104. Alternative embodiments of the power source 110 may include a 240V AC power line. The 240V power line may supply a range of current between about 30 A and about 70 A of current to the thermal cover 104. Various other embodiments may include supply of three phase power, Direct Current (DC) power, 110 V or 220 V power, or other power supply configurations based on available power, geographic location, and the like.	42	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	In one embodiment, one or more modular heated covers 104 are placed on the surface 102 to thaw or prevent freezing of the surface 102. A plurality of thermal covers 104 may be connected by electrical coupling connections 106 to provide heat to a larger area of the surface 102. In one embodiment, the modular heated covers 104 may include a physical connecting means, an electrical connector, one or more insulation layers, and an active electrical heating element. The electrical heating elements of the thermal covers 104 may be connected in a series configuration. Alternatively, the electrical heating elements of the thermal covers 104 may be connected in a parallel configuration. Detailed embodiments of modular heated covers 104 are discussed further with relation to FIG. 2 through FIG. 4.	41	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	In another alternative embodiment, the surface 102 may be ground soil of various compositions. In certain circumstances, it may be necessary to heat a ground surface 102 to thaw frozen soil and melt frost and snow, or prevent freezing of soil and formation of frost and snow on the surface of the soil and thermal cover 104. It may be necessary to thaw frozen soil to prepare for pouring new concrete. One of ordinary skill in the art of concrete will recognize the depth of thaw required for pouring concrete and the temperatures required for curing concrete. Alternatively, the surface 102 may comprise poured concrete that has been finished and is beginning the curing process.	40	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	In various embodiments, the surface to be heated 102 may be planer, curved, or of various other geometric forms. Additionally, the surface to be heated 102 may be vertically oriented, horizontally oriented, or oriented at an angle. In one embodiment, the surface to be heated 102 is concrete. For example, the surface 102 may include a planar concrete pad. Alternatively, the surface may be a cylindrical concrete pillar poured in a vertically oriented cylindrical concrete form. In such embodiments, the thermal cover 104 may melt frost, ice and snow on the concrete and prevent formation of ice, frost and snow on the surface of the concrete and thermal cover 104.	39	Added by DJM 2 2021	2/22/21, 12:00 AM

In the following description, numerous specific details are provided, such as examples of materials, layers, connectors, conductors, insulators, and the like, to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.	37	Added by DJM 2 2021	2/22/21, 12:00 AM
