Abstract: Card-handling devices may include a randomizer configured to randomize ordering of playing cards in a set of playing cards. An output may be configured to present a group of cards at a time from the randomizer for removal from the card-handling device. An image capturer may be positioned and configured to capture image data of at least a portion of each playing card handled by the randomizer, the image data comprising at least a suit and a rank of each playing card. A nontransitory memory device may be operatively connected to the randomizer and to the image capturer, the nontransitory memory device configured to store at least the image data and group assignment data of each playing card in each group of cards presented for removal by the output. A display may be operatively connected to the nontransitory memory, the display configured to display a history of the image data and group assignment data of each playing card in each group of cards presented for removal by the output upon request.

Abstract: The present invention features a playing card shuffling device, which through the use of a small image capturing means, captures an image of a face value of each card and stores the image in memory. This image is sorted in the format of a bitmap image. An operator of the device would be able to recall, through the use of a keypad, the images of the cards that comprised individual hands in the previous game. This feature allows for verification of a winning hand after a game has been completed. Thereby, a quick recheck of hands before playing a winning hand is performed. The face value of each card is determined by character recognition software. These card values would be stored in memory for archival access for use in monitoring the randomness of the game and determining the number of winnings hands.

Abstract: Method of optimizing shuffling of cards with a shuffling machine relying on random ejection technology. Deterministic ejection of cards, verifying card stack position and number of cards remaining in a card stack, adjusting operational functions, including low-impact ejection and packer arm activation, and automatic analysis of card quality create an optimum system for shuffling cards using a shuffler which incorporates random ejection technology. A calibration procedure facilitates the optimization features. In another embodiment, multiple buttons or a single button provide means for an operator to navigate a list of menu items and select a desired menu item.

Abstract: A resonant frequency reciprocating print bar drive mechanism having print bar assembly mass 12 and counterweight 13 held in spaced relationship to each other by first and second leaf springs 16 and 17, which are of equal flexural stiffness. Drive solenoid 14 is mounted between the first and second springs 16 and 17, for inducing reciprocal oscillation between print bar 12 and counterweight 13. The print bar assembly, counterweight and spring assembly is itself suspended as a single unit from perimeter frame 11 by suspension springs 15. Suspension springs 15 have a much lower spring rate than that of leaf springs 16 and 17, and, as a result, the print bar assembly 12 and counterweight 13 will reciprocally oscillate, relative to each other, at a single resonant frequency.
