  • Publication number: 20080265056
    Abstract: Field is ejected from a surface of an apparatus. The apparatus comprises a.) a power supply operating at a frequency; b.) a transducer, which upon being applied the power is made to vibrate with a first amplitude; c.) a vibrating nozzle, comprising the surface, which is acoustically coupled to the transducer, to transmit the transducer vibration to the surface with a second amplitude; and, d.) a control unit to control the power supply applied to the transducer. The fluid is delivered to the surface of the nozzle. During this time the control unit cycles the power applied to the transducer at the frequency between a low power level and a high power level. The fluid is ejected from the surface when the high power level (i.e., first power level) is applied to the transducer but not when the low power level (i.e., second power level) is applied to the transducer.

  • Publication number: 20050163898
    Abstract: An article of commerce comprising an edible substrate having an image which provides value beyond the aesthetic value of the image. In one aspect, the present invention provides an article of commerce comprising: (a) an edible substrate; (b) a first image disposed upon said edible substrate, wherein said first image comprises a first game element; (c) a second image disposed upon said edible substrate, wherein said second image comprises a second game element; and (d) optionally a container for containing said edible substrate. The first game element and the second game element provide elements of a game. In a preferred embodiment, the edible substrate comprises a fabricated snack chip.
