  • Patent number: 11241646
    Abstract: Computer-implemented systems and methods for estimating a replacement status of an HVAC air filter. Outdoor weather data (e.g., outdoor temperature information), is obtained. A Total Runtime Value of the HVAC system is determined based upon the obtained outdoor weather data. Finally, a replacement status of the air filter is estimated as a function of a comparison of the Total Runtime Value with a Baseline Value. By correlating air filter replacement status with an estimated runtime of the HVAC system, a credible predictor of air filter usage is provided. By estimating fan runtime based on easily-obtained outdoor weather data, the methods are readily implemented with any existing HVAC system and do not require installation of sensors or other mechanical or electrical components to the HVAC system.

  • Patent number: 11235555
    Abstract: According to various examples, an assembly can include a backing. The assembly can also include a polymeric surfacing film adhered to the backing, the polymeric surfacing film. The polymeric surfacing film can include a first geometric shape. The polymeric surfacing film includes a continuous first cut defining the geometric shape and a continuous second cut spaced apart from and substantially congruent with the continuous first cut in at least one of an x and y direction. A portion of the polymeric surfacing film, located between the first cut and the second cut, is removable from the backing. According to some examples, the assembly can provide certain benefits over state of the art assemblies. For example, according to some examples, providing the first and second cut can make removal of at least the first geometric shape to be quicker and easier, which can result in significant savings in time and wasted materials.

  • Patent number: 11237340
    Abstract: An optical connector includes a housing having a resilient member and an optical ferrule. The optical ferrule includes a plurality of attachment areas for receiving and securing a plurality of optical waveguides and a light redirecting side for changing a direction of light received from an optical waveguide. The optical connector is configured such that when an optical waveguide is received and secured in any of the attachment areas and light from the optical waveguide propagates along an optical path, the resilient member is not in the optical path. When the optical ferrule mates with a mating optical ferule, the resilient member is resiliently deformed to resiliently force the optical ferrule against the mating optical ferrule.
