    Abstract: A sensor assembly for detecting open or closed state in windows and doors includes a passive infrared sensor configured to produce a change in an electrical signal based on a change in infrared radiation incident on the passive infrared sensor. A lens is operatively connected to the passive infrared sensor. At least a portion of the lens is configured to be mounted in an interface between a frame and a door or window mounted to open and close within the frame. The lens is configured to guide ambient infrared radiation to the passive infrared sensor at a first level when the door or window is closed and at a second level when the door or window is open or ajar.

    Abstract: A method of making an electrocaloric article is disclosed in which a continuous sheet of an electrocaloric film is bent back and forth to form a plurality of connected aligned segments of electrocaloric film with gaps between film surfaces of adjacent aligned segments. The continuous sheet of electrocaloric film is secured in this with a securing method that includes attaching a spacer to the continuous sheet of electrocaloric film prior to the back and forth bending; or providing a spacer comprising a base and a plurality of projections extending from the base, and inserting the projections into the gaps between the film surfaces of adjacent aligned segments after the back and forth bending; or interweaving a continuous spacer through the gaps between the aligned segments of the electrocaloric film; or attaching an end cap to a plurality of connecting portions of the electrocaloric film between the aligned segments.
