  • Publication number: 20240125704
    Abstract: An optical stack for sensing a presence of an analyte is provided. The optical stack includes a sensor material. The sensor material includes a first optical response including a first optical property having a second value in response to an excitation signal including the first optical property having a first value different from the second value. The first optical response includes a second optical property sensitive to the presence of the analyte. The optical stack includes a first optical film disposed proximate the sensor material and includes a third optical property having respective third and fourth values in response to the respective first and second values of the first optical property. The third value is different from the fourth value by at least a factor of 2.

  • Publication number: 20220357069
    Abstract: A robotic system is provided for repeatedly and reproducibly applying a sealant to a seam in an assembled HVAC duct component. The applied sealant has a predetermined location on the assembled HVAC duct component to seal the seam. An assembled HVAC duct component is thus provided having a robot applied sealant on at least one seam in the assembled HVAC duct component, wherein the applied sealant has at least one of a predetermined location, thickness or coverage. The robotically applied sealant can be applied to a blank for forming the assembled HVAC duct component, wherein the sealant is located at locations forming a seam in the assembled HVAC duct component.

  • Patent number: 10883739
    Abstract: An insulated HVAC duct component such as a transition box includes a first insulation layer and a second, different insulation layer. The transition box includes at least four sidewalls and one of a top and a back wall, the transition box further including a first access port and a second access port, the first access port having a different cross section than the second access port, one of the access ports being spaced from a nearest sidewall by less than 2 inches. The first insulation layer is located along an inside surface of the box. The second different insulation layer overlies the first insulation layer, the second different insulation layer having an air impervious surface, wherein the combined thickness of the first insulation layer and the second different insulation layer is less than 2 inches.
