Abstract: Apparatus for pixelating falling water droplets to create a graphical image comprising an elevated water display head formed from a series of two or more modular units. Each of the series of two or more modular units has a water reservoir, a plurality of high speed solenoids located below the water reservoir, a replaceable nozzle plate having a plurality of spaced apart nozzles wherein one of said plurality of high speed solenoids is connected to each nozzle. A programmable micro-controller is provided with each of the modular units for controlling the water supply to the water reservoir and for controlling the formation of the falling water droplets through each solenoid and nozzle. The water droplets falling from said plurality of nozzles from each of the modular units forms part of the graphical image.

Abstract: A simultaneous ascending price auction (“SAA”) can be used to allocate advertising inventory to bidders. The advertising inventory can be, for example, radio or television advertisement spots (“spots”). The bidders can be advertisers that can provide advertisements for presentation in the spots. Two or more contiguous spots can define an advertising block. Spots or advertising blocks can be allocated to advertisers by the SAA mechanism based on bid criteria. The SAA can perform simultaneous advertisement scheduling and pricing. The auction allocation can be optimized to facilitate efficient allocation of advertisements to spots or blocks.

Abstract: An apparatus for pixelating falling water droplets to create a graphical image comprising one or more elevated water display heads having a plurality of spaced apart nozzles in one or more rows, each of said nozzles has a water inlet and a water outlet. A high speed solenoid is provided for each nozzle for opening and closing of the water outlet for each nozzle to control the speed at which water exits the nozzles. A water reservoir is provided above the water inlets for the solenoids and nozzles so that water pressure to the nozzles is maintained by gravity.

Abstract: A apparatus for showcasing falling water images, text and other types of water effects that includes a control means, a pump means that feeds water into a elevated water display head having a plurality of nozzles that alternates at a high speed from an open position to a closed position controlled by solenoids. The modulation of falling water droplets forms a continuous matrix of horizontal water dots that produce scrolling water-formed images.

Abstract: A simultaneous ascending price auction (“SAA”) can be used to allocate advertising inventory to bidders. The advertising inventory can be, for example, radio or television advertisement spots (“spots”). The bidders can be advertisers that can provide advertisements for presentation in the spots. Two or more contiguous spots can define an advertising block. Spots or advertising blocks can be allocated to advertisers by the SM mechanism based on bid criteria. The SAA can perform simultaneous advertisement scheduling and pricing. The auction allocation can be optimized to facilitate efficient allocation of advertisements to spots or blocks.
