1. An apparatus comprising:
- a dimmable window panel having an inner portion and an outer portion around the inner portion;
a heating system thermally connected to the outer portion of the dimmable window panel; and
a sensor system configured to generate data regarding a difference between a first temperature in the inner portion and a second temperature in the outer portion, wherein the sensor system comprises;
a group of strain gauges configured to determine a thermal stress of the dimmable window panel by measuring deformation in a structure of the dimmable window panel.

11. A window system comprising:
-
a dimmable window panel having an inner portion and an outer portion around the inner portion; a heating system thermally connected to the outer portion of the dimmable window panel; a sensor system configured to detect a difference between a first temperature in the inner portion and a second temperature in the outer portion and generate data regarding the difference, wherein the sensor system comprises a group of strain gauges configured to determine a thermal stress of the dimmable window panel by measuring deformation in a structure of the dimmable window panel; and a controller configured to receive the data from the sensor system and control operation of the heating system to maintain a desired temperature difference between the inner portion and the outer portion of the dimmable window panel based on the data received from the sensor system. - View Dependent Claims (12, 13, 14, 15)

16. A method for managing heating of a window system, the method comprising:
-
monitoring a dimmable window panel in the window system for a difference between a first temperature in an inner portion of the dimmable window panel and a second temperature in an outer portion the dimmable window panel determined from an amount of stress and heating the outer portion of the dimmable window panel when an undesired amount of stress is present. - View Dependent Claims (17, 18, 19)
