Abstract: A humidifier includes a modular performance indicator that is removably attached to a grill of the humidifier air outlet. The performance indicator generally includes at least one humidity sensing means and a display. The humidity sensing means is positioned within the airflow for measuring the exit-relative humidity of the airflow and the display is coupled to the humidity sensing means for indicating when the humidifier wick requires replacement and/or the humidifier water supply requires refilling based upon the measured exit-relative humidity reaching a predetermined value.

Abstract: A can opening appliance is provided herein. The appliance includes a primary housing having a front surface including a can opening mechanism and a rearwardly facing locking surface. A base includes at least one upwardly extending projection for slidable engagement with the primary housing and at least one forwardly facing interlock structure for releasable engagement with the locking surface of the primary housing. A housing release button, which causes the forwardly facing interlock structure and the locking surface to enter into and out of engagement, allows the primary housing to attain a plurality of vertical positions relative to the base.

Abstract: A portable humidifier is provided which includes an induction heating system. The system includes an inductor coil and a metal target which functions as a heating element. The metal target is positioned within a tray beneath the inductor coil. The tray is adapted for holding water. The target is coupled to a float, which allows it to move towards or away from the inductor coil depending upon the water level in the tray.

Abstract: A positive temperature coefficient (PTC) heater includes a housing, a fan mounted within the housing, a pair of positive temperature coefficient (PTC) heater assemblies disposed in the housing, and a plenum mounted in the housing. The housing includes a front portion and a rear portion connected together to define a front, a rear, a left side and a right side, the front and rear each having at least one opening. The fan is arranged to produce a flow of air from the rear of the housing to the front. The pair of positive temperature coefficient (PTC) heater assemblies are disposed in side by side relationship and angled relative to each other, each at an angle of approximately 7.5 degrees from normal, so as to produce a diverging column of heated air. The plenum mounted in the housing directs the air flow produced by the fan through each of the PTC heater assemblies.
