Abstract: A relatively lightweight and easy to use flexible heating mat for melting snow and ice that can be cut in the field to custom length or to accommodate direction changes or avoid obstructions. The heating mat includes one or more planar flexible heaters sandwiched between two vulcanized polymer protective sheets. The heating mat may be activated remotely or manually and can be powered from either end of the heating mat. Nonskid patterns ate typically included in heating mats used on driveways and walkways.

Abstract: A lightweight flexible electrical heating device for melting snow and ice that may be cut in the field to custom length. The device includes a planar flexible electric heater sandwiched between two vulcanized polymer protective sheets. The heater include an array of resistive heating elements electrically connected in parallel and oriented substantially across the device length, allowing the heater to be cut to any length as needed. Potentially the outside surfaces is equipped with a ribbed non skid pattern that form an array of ribs and channels to increase traction and aid in water drainage.

Abstract: A removable device for melting and preventing the accumulation of ice and snow on walkway and driveways is disclosed. The apparatus includes a series of interconnected pads of various lengths and widths which are heated to a temperature which is sufficient to prevent the accumulation of ice and snow.
