A sterilization device with dose function is provided. The sterilization device includes a sterilization container, an ultraviolet sterilization module, an ozone sensing module, a sterilization time counter, a dose controller and an ozone removal module. The ultraviolet sterilization module is disposed in the sterilization container to sterilize an article by emitting an ultraviolet light. The ozone sensing module is used to sense an ozone concentration of the sterilization container. The sterilization time counter is used to calculate a sterilization time. The dose controller is used to receive a sensing signal of the ozone concentration and a counting signal of the sterilization time to obtain an ozone dose. The ozone removal module is disposed in the sterilization container to remove or purify the ozone and reduce the ozone concentration in the sterilization container.

An illustrative expendable or reconstructable ozone generator cartridge for an aqueous ozone delivery device, for example, for antimicrobial sanitizing and/or medical treatment, includes a housing for a water treatment manifold providing parallel and operably fixed water pathways through ozone generating cells coupled to the manifold, and optionally a data logging and authentication feature.

A device and methods for intermixing playing cards in a card stack used in casino gaming. The device includes a card-edge lifting structure for lifting the edges of adjacent sub-stacks of playing cards and two push surfaces which translate the sub-stacks closer. When the cards from the adjacent sub-stacks slip past the shaft of the card-edge lifting structure, the cards fall and interleave. The cards are “squared up” and repositioned, completing the card intermixing cycle. The card stack goes through a plurality of card intermixing cycles to obtain the necessary card randomness. Because the card falling is only being acted upon by gravity, the device is simple and compact. A number of embodiments that change the card falling characteristics and the randomness of the card stack are described. A card funnel is further described that allows a card stack to be “squared up” prior to the card intermixing process, minimizing the misalignment of the card stack and potential failures in the card intermixing process.

The present invention relates to methods and devices for diminishing microbes. The invention provides methods and devices to sanitize, disinfect and sterilize areas, spaces, surfaces and items as well as to sanitize human skin.
