Patent ID: 7363502

Claim:
A system for powering up a controller comprising: a power source; a heat generator adapted to receive power from said power source; and a controller adapted to receive power from said power source and adapted to detect a power interruption from said power source to said controller, wherein said controller comprises: a clock for continuously monitoring a current time and a current date; means for copying and storing said current time and said current date; means for calculating a length of time between said detected power interruption from said power source to said controller and a power restoration from said power source to said controller; means for preventing unauthorized power restoration from said power source to said heat generator when said length of time is greater than a predetermined length of time and for restoring power from said power source to said heat generator when said length of time is less than or equal to said predetermined length of time; and means for restoring power from said power source to said heat generator when said length of time is greater than said predetermined length of time wherein said means for restoring power from said power source to said heat generator comprises a password system, wherein said password system comprises means for generating a control password and means for entering an access password, wherein said power is restored when said entered access password matches said control password, wherein said means for generating a control password comprises a predetermined formula, wherein said predetermined formula comprises a plurality of terms and at least one of said terms is a variable term, wherein said control password is numerical and is converted from a base ten number system to a base five number system.
