Abstract: An aerosol generator (100) has a vibratable plate (1) with apertures therein and an annular piezo (2) which causes movement of the vibratable plate (1). An annular support member (3) supports the piezo (2) and the vibratable plate (1). A first electrical power conducting pin (10) engages directly with a first, top, surface of the piezo (2). A second electrical power conducting pin (11) indirectly conducts electrical power to a second surface of the piezo (2), by contacting an extension tab (103) of the support member (20), also on its top side. There is a film of cured epoxy adhesive on the tab (103), providing excellent gripping force between the pin (11) and the support (3). The aerosol generator (100) avoids need for soldered joints for electrical contact, and the pins are conveniently mounted parallel to each on the on the same lateral and top side of the piezo and support member. The pins may have multi-point tips (50) for particularly effective electrical contact.

Abstract: Embodiments herein describe a dripping system that displays an animation using different colored light sources. In one embodiment, the dripping system includes red, green, and blue light sources which can be activated individually or in combination to emit light that reflects off liquid droplets emitted by the dripping system. Controlling the timing of the light sources permits the dripping system to illuminate the water droplets at different locations along their path which generate the animations. In one embodiment, the dripping system changes animations or alters the animation in response to user interaction. For example, different user hand gestures may be mapped to different water droplet animations. An input/output (I/O) system detects the user interaction and changes the displayed animation.
