Abstract: Embodiments disclosed herein are directed to fluid collection assemblies including one or more leak prevention features, systems including the same, and methods of using the same are disclosed herein. An example fluid collection assembly includes a fluid impermeable barrier at least defining a chamber, at least one opening, and a fluid outlet. The fluid collection assembly also include at least one porous material disposed in the chamber and one or more leak prevention features. The leak prevention features may include at least one of a shape of the fluid collection assembly that improves fit between the fluid collection assembly and a patient, at least one absorbent material at least partially disposed outside of the chamber, a base configured to have a patient disposed thereon, or one or more features that allows a length of the fluid collection assembly to change.

Abstract: Techniques for input control visualization include a control console. The control console includes a first input control operable by an operator and outside of a field of view of the operator, a display within the field of view of the operator, and one or more sensors. The one or more sensors acquire information about the first input control and a physical environment surrounding the first input control. A representation of the first input control and the physical environment is generated from the information. The representation is displayed on the display.

Abstract: An air filter includes filter media, a sensor, and circuitry coupled to the sensor, the circuitry configured to receive data from the sensor representative of the condition of the filter media and wirelessly transmit such data. The data may be received by a device with a display to use the information to present an indication of the filter media condition to a user.

Abstract: Devices, systems and methods for obtaining data representative of the condition of an air filter media of an air filter installed in a powered air-handling system, and for using such data to present an indication of the air filter media condition to a user. The devices, systems and methods use pressure information representative of at least a downstream pressure of the powered air-handling system.

Abstract: Systems and methods for monitoring the status of air filters are provided. One or more thermoelectric sensors are provided to have an upstream sensing surface positioned adjacent the inlet surface of the air filter, and a downstream sensing surface positioned adjacent the outlet surface of the air filter. Sensing circuitry are connected to the thermoelectric sensors, configured to receive signals from the thermoelectric sensors and process the signals to obtain status information of the air filter.

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: 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: Devices, systems and methods for obtaining data associated with air filter media of an air filter, and for using such data to generate an air filter recommendation, such as an indication of the air filter media condition to a user, an indication that the filter needs replacing, and/or a recommendation to use a different type of filter.
