Abstract: A leakage protection system for a heating, ventilation, and air condition (HVAC) system can comprise: a power source; a louvered assembly including a frame, slats spaced apart vertically within the frame and extending from a first side to a second side of the frame, an actuator rod operably coupled to the slats, and a spring; a solenoid operably coupled to the actuator rod; and a first pressure switch disposed electrically between the power source and the solenoid.

Abstract: A beverage dispensing device can comprise a housing configured to house a fluid; a feed spout coupled to the housing; and an ultraviolet light emitter coupled to the feed spout, the ultraviolet light emitter oriented in a downward direction during operation, the ultraviolet light emitter configured to emit ultraviolet radiation having an average wavelength between 100 nm and 400 nm.

Abstract: A mechanical control head system allows a vehicle user to control certain HVAC functions. The mechanical control head system includes a mounting plate, a faceplate, at least two user-adjustable actuators, at least two function interfaces and connections between the function interfaces and the HVAC module. The knobs provide the user a means to control, for example, the ambient temperature in the vehicle interior and the outside air circulation within the vehicle. The rotary cylinders can be coupled and uncoupled to the knobs in a single step instead of requiring individual steps for each knob.
