    Abstract: A method of monitoring the condition of an air filter installed in an HVAC system of a building unit. The method involves two-way wireless communication between a sensing unit that is mounted within the HVAC system and a geofencing-enabled app that is resident on a mobile device. Wireless signals between the sensing unit and the mobile device pass through an interior passage of ducting of the HVAC system with the interior passage of the ducting acting as a waveguide. The geofencing-enabled app is configured so that the app is triggered to open communication with the sensing unit upon the mobile device entering a geofencing boundary that is at least generally coincident with lateral boundaries of the building unit.

    Abstract: The present disclosure describes devices for detecting fine and ultrafine particulate matter. The devices may include at least one optical sensor configured at an angle of greater than 90 degrees from a direction of air flow, such that particulate matter is carried away from the sensor. In some examples, a device includes a housing, a light source and a light trap. The light source may be disposed within the proximal end of the housing and can be configured to direct a beam of light toward the distal end of the housing. The light trap may be disposed within the housing to reduce backscatter from the beam of light.

    Abstract: This application describes a back-lit transmissive display including a transmissive display and a variable index light extraction layer optically coupled to a lightguide. The variable index light extraction layer has first regions of nanovoided polymeric material and second regions of the nanovoided polymeric material and an additional material. The first and second regions are disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. The transmissive display may be a transmissive display panel or a polymeric film such as a graphic.

    Abstract: Disclosed herein is an optical device having a light source, a viscoelastic lightguide and a retroreflective film suitable for retroreflecting light. Light from the light source enters the viscoelastic lightguide and is transported within the lightguide by total internal reflection. The transported light is extracted from the lightguide and retroreflected at a structured surface of the retroreflective film. The optical device may have a “front lit” or a “back lit” configuration depending on the relative positioning of the lightguide and the retroreflective film. The retroreflective film may include prismatic retroreflective sheeting, holographic film or film structured with diffraction gratings. The optical device may be used, for example, as a sign or marking, a license plate assembly, a tail light assembly for vehicles, a security laminate for protection of documents against tampering, or an illumination device.
