Paragraph Number

93

In FIG. 9, the thin-film electrical heating elements 904 may be similar to those in the cover 800 described above in relation to FIG. 8. The components of the cover 900 with 900 level numbers may be similar to 800 level components of the cover 800 in FIG. 8. However, these heating elements 904 may include a different pattern 914. In addition, the thickness, size, length, and orientation of the graphite 910 may also be different. In the embodiment of FIG. 9, the graphite 910 may be about 9 inches wide, 5 thousandths of an inch thick, with a separating distance 918 of about ¾ of an inch. In certain embodiments, the graphite 910 may be between 1 thousandths of an inch thick and 40 thousandths of an inch thick. This range is preferred because within this thickness range the graphite 910 remains pliable and durable enough to withstand repeated rolling and unrolling as the cover 900 is unrolled for use and rolled up for storage.
