Abstract: A real-time evaluator decreases the cost of building envelope construction and retrofits by reducing the installation time for overclad panels and enhancing performance of the panels through higher installation quality. The real-time evaluator includes a machine vision subsystem to measure real-time locations of the panels as their being installed, a digital twin manager device to manage a current panel position digital twin based on the real-time measurements and make comparisons to a target panel position digital twin. The comparisons can be used to provide installation guidance to panel installers that can improve both the speed and accuracy of installation.

Abstract: Systems and method for operating an STS panel comprising: a filler with a thermally resistive/insulating material and a first open area (FOA); first and second layers of thermally conductive material (TCM) that are spaced apart, extend parallel, and sandwich the filler such that FOA extends from the first layer of TCM to the second layer of TCM; and a first thermal connector (FTC) disposed in FOA (a) so as to reside between and be spaced apart from the filler, and (b) so as to reside between and be in contact with the first and second layers of TCM. FTC is switchable between a first position in which a thermal bridge is created to allow heat transfer between the first and second layers of TCM and a second position in which the thermal bridge is broken and a thermal gap is created to prevent the heat transfer.

Abstract: A dryer appliance including an air circulation duct is provided herein. The dryer appliance may also include a cabinet, a drum, an air handler, and a heat exchange section. The air circulation duct may define a recirculation loop with the drum. The air circulation duct may define a drum air inlet upstream from the drum and a drum air outlet downstream from the drum. The air circulation duct may further define a predetermined leakage port in fluid communication between the recirculation loop and the interior volume of the cabinet. The air handler may be disposed along the air circulation duct in fluid communication between the drum air outlet and the drum air inlet. The heat exchange section may be disposed along the air circulation duct in thermal communication with air within the recirculation loop.

Abstract: Refractometers for simultaneously measuring refractive index of a sample over a range of wavelengths of light include dispersive and focusing optical systems. An optical beam including the range of wavelengths is spectrally spread along a first axis and focused along a second axis so as to be incident to an interface between the sample and a prism at a range of angles of incidence including a critical angle for at least one wavelength. An imaging detector is situated to receive the spectrally spread and focused light from the interface and form an image corresponding to angle of incidence as a function of wavelength. One or more critical angles are identified and corresponding refractive indices are determined.
