Abstract: A humidifier includes a container for containing a fluid; a cartridge for nebulizing the fluid, the cartridge configured to be fixed inside the container, the cartridge including a cartridge housing including a bottom side that is configured to contact a bottom of the container, a top side opposite to the bottom side; a back side; a front side; a left side; and a right side; and a handle on the top side of the cartridge housing, the handle projecting upward and away from the cartridge housing.

Abstract: In some examples, a device controls a heating, ventilation, and air conditioning (HVAC) system within a building. The device includes an analog display including a set of markers, a stepper motor, and a pointer connected to the stepper motor. Additionally, the device includes processing circuitry configured to control the stepper motor in order to cause the pointer to indicate a first marker of the set of markers, wherein the first marker corresponds to a current parameter value and control a dial to indicate a set point parameter value by indicating a second marker of the set of markers which corresponds to the set point parameter value.

Abstract: In some examples, a device can control an HVAC system within a building. Includes an analog display including a set of markers, and where each marker of the set of markers corresponds to a respective parameter value of a parameter associated with the building; an electric motor; a pointer connected to the electric motor, where the electric motor is configured to rotate the pointer within a pointer range from a lower limit to an upper limit; and processing circuitry. The processing circuitry is configured to: determine a position of the electric motor while the pointer is positioned at one of the lower limit or the upper limit of the pointer range; and calibrate, a position function corresponding to the electric motor.
