Abstract: INTEGRATED CIRCUIT RF AMPLIFIER MODULE       Abstract of the Disclosure A four-terminal integrated circuit high-frequency RF amplifier connects to external circuitry via a ground terminal, an RF input terminal, an RF output terminal and a DC biasing terminal.  A two stage amplification architecture is employed  -  a current gain transistor (common-emitter) is cascoded with a subsequent voltage gain transistor (common-base) while yet maintaining RF signal inversion overall from input to output so as to increase stability.  A biasing current-mirror transistor provides biasing current to the current-gain transistor.  A fourth transistor connected as a forward-biased collector-base shorted diode between the current mirror biasing transistor and a common external biasing terminal supplies bias current to the current-mirror biasing transistor while simultaneously minimizing voltage swings across the current-gain transistor.  The amplifier module has very low input capacitance which does not change appreciably with changes in load impedance, and operates with great stability under a wide range of different input and output conditions and RF frequencies.  Because of its relative simplicity and compactness, the amplifier can be used to great advantage as an IC "building block" in a variety of different applications.

Abstract: ABSTRACT OF THE DISCLOSURE           An automatic gaming system for games of chance, such as BINGO or the like, is disclosed comprising a system base station, a plurality of electronic gaming boards, and a plurality of validation units.  The electronic gaming boards are initialized by the system base station with a complex gaming schedule developed by the system operator.  The system base station includes an interactive program means to create a complex gaming schedule having completely arbitrary win patterns, multiple levels of payouts, and multiple place win combinations.  The system base station further loads each gaming card with data representing a variable time interval which causes all of the boards to enter the play mode at the same time.  The validation units are initialized by the system base station with a validation code which is used when checking a win claim of an electronic card.  The validation units store audit information gained during the the validation of win claims and upload that stored information to the system base station at the end of a gaming session.  The system base station further includes a program to command the electronic gaming boards and validation units to turn off or on.          The invention further discloses an electronic gaming system for playing games.  The system includes a system base station and a plurality of electronic gaming boards.  The system base station downloads game instructions, a game schedule, and game card arrays into the gaming boards.  These game card arrays are stored in the system base station as a gaming card library.  The game schedule stores symbols which are to be matched with randomly generated symbols, particularly where the symbols are numbers and the pattern is a plurality of elements of a 5 x 5 array.  The system base station retains auditing information about the distributed gaming cards; thus, the base station instantly confirms matches between the randomly-called numbers and those on a winning card, and at the same time verifies that such a card was indeed sold.  The system base station receives information and performs supervisory functions such as distributing the game cards, storing the distributed game cards in memory, validating potentially winning cards, calculating card cost, calculating prize money for each session, and processing and reporting cumulative audit records stemming from the entire gaming session.  The system base station has a number of modes by which an operator performs various functions for a gaming session as either the manager of the gaming session, the cashier of the gaming session, or the accountant of the gaming session.  The accounting function produces a comprehensive audit record, including a profit/loss statement and a final cash-on-hand balance, for the entire gaming session.

Granted: 1991-08-20
Abstract: "ASSEMBLY OF VARIABLE-WIDTH GRAVITY-FEED BEVERAGE-CONTAINER DISPENSER ARRAY FROM SINGLE-LANE COMPONENTS"                           ABSTRACT   In the rack mounting and display of chilled beverage containers, for ready access and withdrawals by retail custo-mers, the gravity-feed forwardly-inclined shelving having multiple parallel lanes for upright presentation of the containers is formed by combinations of laterally-interlocked identical molded-plastic modules.  Each elongated narrow module is of a high-strength ribbed construction and exhibits an upstanding narrow guide wall fully along one edge; when several such modules are joined side-by-side, via separable fastening provisions such as those composed of integral pegs depending from along one edge and accommodating recesses disposed in a narrow ledge along the other, the single guide walls cooperate to define the individual lanes or paths along which the containers must slide from back to front.  Widths of the shelf assemblies are determined by the numbers of modules which are locked together, thereby allowing for fits within different widths of available space, and for adjustments of displays to offer something other than a standard number of selections.
