Abstract: An air quality control system adapted for use with an entryway for a room, includes a touchless door adapted for association with the room and a door sensor associated with the touchless door to determine whether the touchless door is open or closed. An air purifier selectively deactivates pathogens and pollutants in air flowing through the air purifier and an air quality sensor positioned near the touchless door measures at least one parameter, whereupon the air quality sensor selectively activates and deactivates the air purifier based on whether a threshold level of the at least one parameter is exceeded or not.

Abstract: A walking animal toy includes a battery-powered motor driven apparatus for moving the animal legs to produce a walking action. An independent motor and drive is operative to provide tail wagging of the animal toy. A collar is rotatably secured to the neck portion of the animal toy and receives one end of an elongated flexible tether. The remaining end of the flexible tether is secured to a hand controller including a user handle and a control thumb switch also operable by the user. A plurality of batteries are supported with the hand controller and together with the thumb switch are coupled to the operative mechanism within the animal toy through wires passing through the tether.
