Patent ID: 8454228

Claim:
A testing device for thermal detectors, comprising: a hollow circular heat conductive sleeve, open on at least one end, configured to receive a thermal detector; a flexible foil heater in proximity to at least a portion of the hollow heat conductive sleeve; a power source configured to provide power to the flexible foil heater; a conic funnel coupled to an open end of the hollow heat conductive sleeve where an inner diameter of the conic funnel is the same as the inner diameter of the hollow heat conductive sleeve and at least partially thermally isolated from the hollow heat conductive sleeve, operable to guide a thermal detector into the hollow heat conductive sleeve; and a heat shield substantially surrounding the hollow heat conductive sleeve and the flexible foil heater, and thermally insulated using spacing in a radial direction from the hollow heat conductive sleeve and the flexible foil heater so as to be safe for human touch during operation of the heater.
