Patent ID: 7423243

Claim:
A system, comprising: a fluid receptacle having a fluid reservoir, said fluid reservoir configured to retain fluid; and a heating control system configured to heat the fluid retained within said fluid reservoir, said heating control system comprising: a processing unit; at least one fluid temperature sensor positioned on or within at least a portion of said fluid receptacle; said at least one fluid temperature sensor being in communication with said processing unit, said at least one fluid temperature sensor being configured to detect a temperature of the fluid within said fluid reservoir; at least one air temperature sensor in communication with said processing unit, wherein said processing unit is configured to selectively activate and deactivate said heating element based on a temperature of ambient air; a heating element configured to heat the fluid within said fluid reservoir; and a power switch disposed within an electrical path between said heating element and said processing unit, said processing unit being configured to activate said heating element through said power switch when said at least one fluid temperature sensor detects that the temperature of the fluid within said fluid reservoir is below a first threshold, and said processing unit being configured to deactivate said heating element through said power switch when said at least one fluid temperature sensor detects that the temperature of the fluid within said fluid reservoir is above a second threshold.
