A liquid container includes a liquid pack having a flexible pouch holding the liquid, a container body containing the liquid pack, an expandable-and-contractile stirring chamber formed in the container body, and a pressurized fluid supply passage for supplying a pressurized fluid into the stirring chamber. A plurality of spinning reels, each reel having a plurality of symbols of a combination game are displayed on the first display. As with other known perovskite materials, this is accompanied by nonvolatile changes in electro-optic properties related to dispersion and absorption of electromagnetic radiation. A plurality of processing nodes are adapted to use the plurality of selectable parameters to assemble a first plurality of data from the first and second data repositories and from input data, to reduce the first plurality of data to form a second plurality of data, and to aggregate and dimension the second plurality of data for storage in the multidimensional data structure. Another type of pre-equalization system provides a signal at its output which is ATSC compliant in some respects but which retains the ECR signal, and therefore is particularly useful for signal relays, analysis purposes, and other applications in which the residual channel information is important.
