A smoking device for aerosol-generation may comprise a device housing, a surface acoustic wave-atomizer (SAW-atomizer), a supply element, and a control system. The device housing may include a storage portion for an aerosol-forming substrate. The SAW-atomizer may include an atomization region, a first transducer, and/or a second transducer. The first transducer is configured to generate first surface acoustic waves that propagate along a surface of the SAW-atomizer. The supply element is arranged to supply the aerosol-forming substrate from the storage portion to the atomization region of the SAW-atomizer. The control system is configured to operate the SAW-atomizer to atomize the aerosol-forming substrate in the atomization region to generate an aerosol. A cartridge for such a smoking device and a method for generating an aerosol in a smoking system are also provided.

The complete system for a portable diffusing device, including diffusing engine, housing, delivery of active materials, active material reservoir container, power source, user interface with the device, as well as a case enclosing the device, is described in this invention. The device incorporates a piezoelectric dispersion mechanism with a staged active material delivery mechanism, allowing for ease of removal and/or replacement of the active material reservoir container via a simple means of attachment or detachment. The invention can comprise either one complete system housed in one device, or a multiplicity of systems housed in one device. The device of the invention also incorporates an on-board power source allowing for portability of the device, as well as a direct interface mechanism and/or a wireless mechanism for user control of the device. The invention also includes a case for housing, charging, and communicating with the device.

A dispenser and methods for transferring liquids are disclosed. The dispenser may include a capillary tube with tip having an aperture, a piezoelectric actuator coupled to the capillary tube at a location. Actuation of the piezoelectric actuator causes a pressure wave to propagate along the capillary tube toward the tip such that radial motion at the location is transmitted as distally extending axial motion of the tip, thereby causing a droplet of a predetermined volume to be ejected from the aperture. In some embodiments, the capillary tube has a modulus of elasticity in a range which dampens acoustical noise from the actuation and provides single drop stability over a range of drop sizes.

A dual chamber ultrasonic essential oil diffuser or nebulizer or more specifically to a diffuser having a reservoir or first chamber specifically for distilled water, a second air transfer chamber having a replaceable aroma cartridge and the diffuser being capable of mixing the nebulized water mist and essential oil aroma away from the transducer.

A device and method for vaporizing game liquid attractants are provided. The vaporizing device has a container suitable for holding vaporizable liquid therein, a wick, a transducer operably connected to a power supply, and a controller. Vaporizable liquid, preferably game attractant or a mixture thereof is drawn to the transducer by the wick. When supplied with electrical current from the power supply, the transducer oscillates at a high frequency sufficient to vaporize the vaporizable liquid drawn to the transducer via cavitation. Once vaporized, game attractant vapor may be diffused or propelled through an outlet in the container to the external hunting environment.
