  • Patent number: 6172658
    Abstract: A method and apparatus for producing an image defined by fluid bubbles in a medium fluid. Alphanumeric digits and/or graphic images in a fluid medium are formed by injecting into the fluid medium a multitude of fluid bubbles having a density different than that of the medium fluid. Using non-gaseous fluids, the fluid bubbles take on a natural shape which is not confined by any structures as it travels through the medium fluid. The rate at which the fluid bubbles rise or fall through a medium fluid is directly dependent on the viscosity of the individual fluids and the difference between the fluid viscosities. The viscosity of the medium fluid also influences the rate of formation of bubbles which are being created. The control and timing circuitry determines the time interval wherein each horizontal row of bubbles is created. The rows of bubbles then create a 2-D or 3-D image, conducive for various applications as signs or displays.

  • Patent number: 6070348
    Abstract: A visual display device which produces a display utilizing bubbles emitted in liquid filled tubes. A computer controls the timing and size of bubbles emitted into the liquid so as to form designs, which can be symbols, letters, words, or sentences, or pictures. As the bubbles rise through the liquid in a tube, the designs appear to scroll upward, and are replaced from below with a new design.

  • Patent number: 5758824
    Abstract: Pressurized fluid enters by way of the flow control valve 90 which regulates flow and thus simulated raindrop size, through the fluid supply tube 80 and enters the fixed fluid distributor body 20, past a rotational seal 154 and into the rotating shaft 10, cushioned by the accumulator chamber 50. As the rotating shaft is made to rotate by means of the drive motor 60 and transmission means 70, the radial outlet port(s) 14 sequentially line up momentarily with each side port 26, allowing fluid flow through each outlet tube 30-35 in turn overflowing each respective conical vessel 40-45 to create a fluid drop at the lower point 48 which falls as simulated rain 160 in a desired three dimensional array. Each raindrop is thus timed perfectly according to the speed of rotation of the rotating shaft 10. The transducer 100 produces an electrical pulse for each rotation, also perfectly timed to the raindrops, which is input to the triggered oscillator 110 to ultimately control the strobe light 140.

  • Patent number: 5678617
    Abstract: This invention involves a Jumping Drink Bar Device. This document discloses a novelty device for installation in a bar or counter whereby when a patron orders a specific drink the bartender or host places a drinking glass upon a designated location on top of the bar and, unknown to the patron, activates a hidden control. The drink then seems to hop from some remote spot on the bar and take one or more leaps, ultimately landing in the patron's glass.

  • Patent number: 5426878
    Abstract: An amusement device which includes a transparent tank filled with a liquid medium such as water. Contained within the tank is a plurality of uniform diameter, positive and negative buoyant spheres. Disposed inside the tank is a downward directional tubal system and an upward directional tubal system which are used to move the spheres in opposite directions of their buoyancies. Located beneath the floor of the tank is an air pump which feeds air into the tubal systems to create currents which forcibly move the spheres through the tubes. Also disposed in the tank are downward and upward directional tracks which route the spheres to their respective staging areas, depending upon their buoyancies. For example, positive buoyant spheres travel upward in the liquid medium along the underside of the upward directional track while the negative buoyant spheres travel downward in the liquid medium along the top side of the downward directional track.

  • Patent number: 5363577
    Abstract: A liquid display that has a plurality of adjacent parallel tubes filled with a fluid and connected to a source of air that introduces bubbles into the tubes, so that the combination of bubbles form a word, or another recognizable graphic display. Each tube has a valve connected to the air supply, that controls the duration and flowrate of air injected into the tube so that a single bubble is formed within the tube. The valves are connected to a computer that opens and closes each valve to produce a pattern of bubbles in accordance with a computer program within the computer. The program creates a combination of bubbles that together depict a legible design or display.

  • Patent number: 5349771
    Abstract: A rising bubble display device includes a reservoir with a lamp positioned beneath the reservoir. An air pump is mounted adjacent the lamp to pump air via orifices located at the base of the reservoir. A translucent colored element is interposed between the lamp and the reservoir, and this colored element is releasably retained in place such that the user can readily substitute one colored element for another to change the color of the illuminating light. An orifice defining tube is mounted to the reservoir by a sleeve and a threaded cap to provide the necessary seal while allowing ready removal of the orifice defining tube. The reservoir is secured to the base in channels, and the tube is connected to the air pump with a check valve. In this way, the reservoir can readily be isolated from the pump and removed from the base for service.
