  • System for and method of controlling the temperature of an object using temperature control elements spaced from the object
    Patent number: 6114671
    Abstract: A system for and a method of controlling the temperature of an object (22). Temperature sensors (30) are placed on the object (22) in abutting zones (24) substantially covering a surface of the object (22), so as to detect a temperature in each of the respective zones (24). Temperature adjusting elements (28) are spaced from and thermally coupled to the object (22), to adjust the temperatures of corresponding ones of the respective zones (24). Temperature control circuits (32, 34, 36), responsive to temperatures detected by respective ones of the temperature sensors (30), control the corresponding ones of the temperature adjusting elements (28) to maintain the temperatures of the respective zones (24) within a preset temperature range. When the object (22) is in a cold environment and is to be maintained at a warmer temperature, the temperature adjusting elements (28) are heating elements.
