Abstract: A matrix-patterned cloth includes: first and second fiber layers including mutually isolated first and second conductors, respectively; an intermediate fiber layer between the first and second fiber layers; conductive connecting yarns connecting one of the first conductors and one of the second conductors, wherein, when a pressure is applied to the matrix-patterned cloth, each connecting yarn bends so that a position of contact between the connecting yarn and the first or second conductor changes depending on how large the pressure is; a selector; and a heating controller or a resistance measuring unit. The selector scans and sequentially selects one of the first conductors and one of the second conductors. The heating controller applies voltage to intersecting areas where the selected first and second conductors intersect each other via the first and second conductors. The resistance measuring unit measures electric resistances of the intersecting areas via the first and second conductors.

Abstract: A snow melter, comprising a melting assembly and a handle assembly. The melting assembly comprises a melting plate which contains an electric heating element. The melting assembly also has a top plate which is made of an insulating material, and a bottom plate which is porous or has a grating for allowing snow to contact the melting plate but prevents the user from inadvertently contacting the melting plate. The handle assembly has a proximal end having upper and lower handgrips, and a distal end which attaches to the melting assembly. The distal end is preferably attached to the melting assembly at an operating angle which is substantially ten to twenty five degrees from a normal line to the point of attachment between the handle assembly and the melting assembly. An extension cord connects the melting plate to a power source, and is preferably mounted on a spring loaded spool which is located near the distal end of the handle.
