摘要： An indoor air quality (IAQ) system for a building includes an IAQ sensor that is located within the building and that is configured to measure an IAQ parameter. The IAQ parameter is one of: an amount of particulate of at least a predetermined size present in air; an amount of volatile organic compounds (VOCs) present in air; and an amount of carbon dioxide present in air. A mitigation module is configured to: selectively turn on a mitigation device based on a comparison of the IAQ parameter with a first ON threshold and a second ON threshold; and selectively turn off the mitigation device based on a comparison of the IAQ parameter with an OFF threshold. A clean module is configured to determine a clean value for the IAQ parameter. A thresholds module is configured to, based on the clean value, determine the first ON threshold and the OFF threshold.

摘要： The present invention provides an air purifier which includes an outer case (10) having a filtering cavity (15) and a driving cavity (16) space apart from each other, a filter (20) received in the filtering cavity (15), a driving fan (30) received in the driving cavity (16). The outer case has at least one air inlet (17) and an air output arrangement (11). The air purifier further includes an air hub (40) provided between the filtering cavity (15) and the driving cavity (16). The air hub (40) includes a first air drawing frame (41) and a second air drawing frame (42). The first air drawing frame (41) extending within a central cavity (21) of the filter (20) and is coaxially formed with respect to the filter (20). An axial direction of the first air drawing frame (41) is aligned with a longitudinal axis of the driving fan (30). The second air drawing frame (42) peripherally, upwardly and radially extends from the first air drawing frame (41) toward an upper end of the filter (20). The first air drawing frame (41) and a second air drawing frame (42) increase total surface area for air flow and reduces air resistance and noise.

摘要： An electronic device includes a housing having a hole formed therein, an audio device inside the housing and communicating with an outside of the electronic device through the hole, a gas sensor inside the housing and communicating with the outside through the hole, a proximity sensor inside the housing, a wireless communication module inside the housing, and a processor inside the housing. The processor is configured to acquire data associated with air outside the electronic device by using the gas sensor, to recognize a user gesture of starting a proximity call by using the proximity sensor, and to calculate air quality of the outside air based on at least one of data acquired by the gas sensor before the proximity call starting gesture is recognized and data acquired by the gas sensor after a gesture of ending the proximity call is recognized. Other various embodiments are possible.

摘要： A control system for a mitigation device includes a processor and a computer-readable medium that includes instructions executable by the processor. The instructions include monitoring a first measured particulate matter (PM) level of a conditioned space. The first measured PM level includes PM having a first range of sizes. The instructions further include monitoring a second measured PM level of the conditioned space. The second measured PM level includes PM having a second range of sizes. The first and second ranges are different but overlapping. The instructions also include asserting, in response to the first measured PM level being greater than a first predetermined threshold, an activation signal. The activation signal forces operation of a fan of the mitigation device. The instructions include asserting, in response to the second measured PM level being greater than a predetermined percentage of the first measured PM level, the activation signal.
