Claim 16:
17. A method for a structure including a window, the structure defining an opening, the window being operatively positioned within the opening, the window being movable to selectively open and close the opening, the window including an optical grating operatively positioned near a closing edge of the window, a light source configured to emit light toward the optical grating, a detector operatively positioned to acquire spectroscopic data of the light emitted from the light source after the light has interacted with the optical grating, the method comprising:
determine a temperature based on the spectroscopic data;
determine, based on the temperature, whether an object is located in the opening; and
responsive to determining that an object is located in the opening, control a movement of window.
