An electrical device capable of interfacing with multiple types of duplex receptacles includes at least one set of moveable outlet prongs that are adjustable such that they may be readily inserted into outlets of varying dimensions. Adjustability may be provided by, for example, a rotable or translatable connection between the prongs and one of the outlet plugs of the device. The prongs may be biased into position by a spring or other elastic member. By providing adjustable prongs on at least one outlet plug, the device is able to interface with both outlets in duplex receptacles of various sizes and types, including receptacles having ground fault circuit interrupter (GFCI) capabilities.

A vapor-dispensing or other environment-altering apparatus is configured to integrate with a receptacle in a discreet manner. In accordance with one embodiment of the invention, an environment-altering apparatus is configured to mimic an electrical receptacle having an outlet pattern. The environment-altering apparatus has a front surface which includes an outlet pattern substantially corresponding to the outlet pattern of the electrical receptacle, and a plug configured to interface with the electrical receptacle. A device configured to modify one or more attributes of the environment is interposed between the front surface and plug pattern. These attributes include, for example, aromatic vapor density, insecticide vapor density, ambient light intensity, ionic air content, ultrasonic frequency intensity, and the like.

An improved variable resistor at least partially compensates for non-linearities in an electrical circuit containing a heating element, for example, a thin-film heating element. A controllable heater includes a heating element, a voltage source (for example, a standard AC electrical outlet) coupled to the heating element, and a variable resistor coupled to the heating element and voltage source. The variable resistor includes a fixed resistive element (for example, one or more thin-film resistors) and a moveable element such as a slider control. The moveable element adjustably contacts the fixed resistive element at a contact point associated with the position such that the variable resistor has a resistance that is at least partially non-linearly related to the position, but wherein the heating element has a dissipated power that is at least partially linearly related to the position of the variable resistor. Such a system may be used in conjunction with a vapor-delivery device to provide more linear control over the intensity of fragrance provided within an environment.

A multiple-outlet vapor-dispensing device is configured to interface with an electrical receptacle such that the functionality of that outlet is substantially maintained. In accordance with one aspect of the present invention, a vapor-dispensing device is configured to connect to an electrical receptacle having at least one outlet. The vapor-dispensing device comprises a housing having a first device outlet and a second device outlet, the housing being attachable to the outlet.

A vapor dispensing device having a high transverse loading stability includes a relatively low profile with respect to the supporting wall or electrical receptacle such that the frequency and impact of accidental physical contact with the device are appropriately reduced. To achieve a low profile, the housing of a vapor dispensing device is designed such that the distance from the outlet face of the wall receptacle to a worst-case transverse loading point (dL) is less than the distance from the plug to a worst-case support point (dS).

An air purifier having dimensions that enable the air purifier to be more discrete is disclosed. The air purifier also includes components that enable the air purifier to mimic a particular environment in which the air purifier may be placed. In addition, the air purifier includes electrical plugs such that the air purifier is able to be plugged into a traditional wall outlet and the components enable the air purifier to mimic the appearance and function of the wall outlet. Furthermore, the air purifier includes one or more modules to sanitize incoming air, facilitate air flow through the air purifier, and/or dispense scented vapors.

The present invention suitably provides a method and apparatus for controlling the temperature of a liquid vaporizer heating element, and thereby the rate of evaporation and level of fragrance delivery from the same. In accordance with one exemplary embodiment of the present invention, the device may include a switch that suitably allows the temperature of various types of heating elements to be controlled for different levels of fragrance output. For example, an exemplary embodiment may include a two-pronged plug adaptable to typical outlets that might be found in residential homes or businesses. In accordance With another exemplary embodiment of the present invention, the electrical switch generally provides varying resistance values to the electric circuitry of the vaporizer such that, by changing the switch setting, the operating temperature of the wick is controlled and thus the rate of fragrance evaporation from the vaporizer.
