View Edit Delete	US7230213A1	In one embodiment, the thermal cover 700 may additionally include a power connection 714 between the 120V power line, and one 120V phase of the 240V power line. In certain embodiments, the connection 714 provides power to a first active electrical heating element 716 when the 240V power connector 704 is plugged in. In one embodiment, the 240V power connector 704 may additionally provide power to a second active electrical heating element 718. The 120V power connector 702 may provide power to the first active electrical heating element 716, but not the second active electrical heating element 718. For example, if the 120V power connector 702 is connected to a power source, only the first active electrical heating element 716 is powered. However, if the 240V power connector 704 is connected to a power source, both the first active electrical heating element 716, and the second active electrical heating element 718 are powered. In this example, the first active electrical heating element 716 is powered by the 240V connector through the power connection 714.	76	Added by DJM 2 2021	2/22/21, 12:00 AM

In one embodiment, the thermal cover 700 includes one or more 120V plug connectors 702, one or more 240V plug connectors 704, one or more 120V receptacle connectors 706, and one or more 240V receptacle connectors 708. Additionally, the thermal cover 700 may include one or more power bus connections 710 for a 120V power connection, and one or more power bus connections 712 for a 240V power connection.	75	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	The powered lines of both the 120V plug 602 and the 240V plug 604 may be connected to a directional power diode to isolate the power provided from the other plug. Alternatively, a power transistor, mechanical switch, or the like may be used in the place of the directional power diode to provide power isolation to the plugs. In another embodiment, the both the 120V plug 602, and the 240V plug 604 may include waterproof caps (not shown). In one embodiment, the caps (not shown) may include a power terminating device for safety.	74	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	Beneficially, the apparatus 600 provides high versatility for power connections, provides variable heat intensity levels, and the like. For example, the first active electrical heating element 608 and the second active electrical heating element 610 may be configured within the thermal cover 200 at a spacing of four inches. In one embodiment, the first active electrical heating element 608 and the second active electrical heating element 610 connect to a hot and a neutral power line. The electrical heating elements may be positioned within the thermal cover 200 in a serpentine configuration, an interlocking finger configuration, a coil configuration, or the like. When the 120V plug 602 is connected, only the first active electrical heating element 608 is powered. When the 240V plug 604 is connected, both the first active electrical heating element 608 and the second active electrical heating element 610 are powered. Therefore, the resulting effective spacing of the electrical heating elements is only four inches.	73	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	In one embodiment, the safety ground lines from the 120V connector 602 and the 240V connector 604 are connected to thermal cover 200 at connection point 612. In one embodiment, the safety ground 612 is connected to the heat spreading element 210. Alternatively, the safety ground 612 is connected to the outer layers 302, 310. In another alternative embodiment, the safety ground 612 may be connected to each layer of the thermal cover 200.	72	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	In one embodiment, the directional power diode 606 is specified to operate at 240V and up to 70 A. The directional power diode 606 allows electric current to flow from the 240V line to the first electrical heating element 608, but stops electric current flow in the reverse direction. In another embodiment, the directional power diode 606 may be replaced by a power transistor configured to switch on when current flows from the 240V line and switch off when current flows from the 120V line.	71	Added by DJM 2 2021	2/22/21, 12:00 AM
View Edit Delete	US7230213A1	In one embodiment, the first electrical heating element 608 is powered when the 120V plug 602 is connected, but the second electrical heating element 610 is isolated by the directional power diode 606. In an additional embodiment, the first electrical heating element 608, and the second electrical heating element 610 are powered simultaneously. In this embodiment, the first electrical heating element 608 and the second electrical heating element 610 are coupled by the directional power diode 606.	70	Added by DJM 2 2021	2/22/21, 12:00 AM
