    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: A non-contact friction ridge capture device is described. The device comprises a device housing, the device housing including an electronics compartment and an illumination shield, with an opening between the electronics compartment and the illumination shield into which a user can insert the user's hand. The device further comprising a camera disposed in the electronics compartment for capturing an image of at least one friction ridge surface on a user's hand. The device further comprises a light source disposed in the electronics compartment, the light source emitting light in the direction of the illumination shield, wherein the peak wavelength of emitted light is in the range of 440 to 570 nanometers (nm). The user's hand is not required to contact the device when the camera captures the image of at least one friction ridge surface on a user's hand.

    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 optical device may have a "front lit" configuration such that light being transported within the lightguide is extracted and retroreflected by the film toward a viewer. The optical device may have a "back lit" configuration such that light being transported within the lightguide is extracted and transmitted through the film toward a viewer. The retroreflective film may comprise beaded retroreflective sheeting such as that used in traffic signs and markings.

    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.
