1. An apparatus for heating a window comprising:
- a selectively movable switch which is movable from a first position to a second activated position;
an assembly which is coupled to said selectively movable switch and which provides controlled pulses of energy only when and for as long as said switch is in said second activated position;
a first portion which is communicatively coupled to said assembly and deployed upon a first part of said window, wherein said assembly communicates said controlled pulsed energy to said first portion and, in response to said receipt of said controlled pulsed energy, said first portion heats said first part of said window; and
a second portion which is communicatively coupled to said assembly and deployed upon a second part of said window, wherein said assembly communicates said controlled pulsed energy to said second portion only after said first part of said window has been heated, thereby heating said second part of said window.

Abstract
A method and an apparatus 12 for quickly heating a portion of a vehicle 10, such as a windshield 22 or backwindow 20. Particularly, apparatus 12 includes several conductors 40 which are coupled to electrical ground potential 42 and which have opposed ends 44, 46 which are alternatingly coupled to a source of energy 26, thereby allowing the portion of the vehicle 10 to be quickly heated.

10. An assembly for heating a portion of a vehicle comprising:
-
a selectively movable switch which is movable from a first position to a second activated position;
a plurality of conductors which heatingly communicate with said portion of said vehicle, each of said plurality of conductors being coupled to an electrical ground potential and including a first portion which selectively receives pulsed energy and which produces heat by use of said pulsed energy only when and for as long as said selectively movable switch is in said second activated position;
a control assembly which estimates the temperature of said portion of said vehicle by determining the resistance of said pulsed energy, said control assembly further storing a threshold temperature level and, upon said first portion reaching said stored threshold temperature level, said control assembly interrupting said communication of pulsed energy to said first portion; and
a second portion which selectively receives said pulsed energy and which produces heat by use of said pulsed energy only when and for as long as said selectively movable switch is in said second activated position and only when said communication of said pulsed energy to said first portion is interrupted by said control assembly. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method for heating a vehicular window comprising the steps of:
-
providing a battery;
providing a selectively movable switch which is movable from a first position to a second activated position;
providing a control assembly and coupling said control assembly to said battery and to said selectively movable switch, wherein said control assembly causes said battery to emit pulsed energy only when and for as long as said switch is in said second activated position;
providing a first plurality of conductors and coupling said first plurality of conductors to said battery, said first plurality of conductors receiving said controlled pulsed energy from said battery and, upon reception of said pulsed energy, said first plurality of conductors producing heat only when and for as long as said selectively movable switch is in said second activated position, wherein said control assembly further interrupts said communication of said controlled pulsed energy to said first plurality of conductors only upon a determination that said first plurality of conductors have reached a certain threshold level; and
providing a second plurality of conductors, said second plurality of conductors only receiving said controlled pulsed energy from said battery after said control assembly has interrupted said controlled pulsed energy to said first plurality of conductors and, in response to said received pulsed energy, said second plurality of conductors selectively produce heat only when and for as long as said selectively movable switch is in said second activated position. - View Dependent Claims (17, 18, 19, 20)
