Abstract
A thermal compensation system is provided for a liquid-filled inflexible chamber of a device. The chamber has at least one exposed, at least partially transparent surface allowing an outside observer to observe at least one liquid and comprises a mechanism accommodating thermal expansion and/or contraction of the liquids. The mechanism is disposed so as to be substantially invisible to the observer.
