Abstract: A faucet includes a spout configured to direct fluid into a sink, a camera arranged to capture images of the sink, and a processing circuit. The processing circuit may receive an image from the camera. The image may include an object positioned beneath the spout. The processing circuit may analyze the image received from the camera to assign a classification to the object included in the image. The processing circuit may cause the spout to direct fluid into the sink with fluid flow characteristics that correspond to the classification of the object in the image.

Abstract: An active air cleaning controller is connected to a forced air heating, ventilation and air conditioning (HVAC) system. The active air cleaning controller uses call signals from a thermostat to the HVAC system and/or sensor signals to determine when, and for how long, the blower of the HVAC system has been active and whether to independently activate the blower. The active air cleaning controller uses at least the collected information regarding the blower run time to determine when to activate the blower, in addition to its use within the HVAC system, to cycle and thus clean the air in a living environment independently of call signals used to activate heating and/or cooling functions of the HVAC system.
