  • Patent number: 8567787
    Abstract: A word game system for playing multiple word games and its corresponding play methods are disclosed. The game system and the multiple word games are all based on the word scramble process—constantly and dynamically scrambling the playing pieces to form words by all the players all the time, hence extremely stimulating and entertaining. The game system and its specific set of playing pieces with proper ranking distribution, value point assignments, math function selections and incorporation of wild playing pieces support a host of brain stimulating games including Scramble Word, Scramble Poker and Scramble Ma-Jong. These word games are playable in English and other languages and playable as board, computer, broadcasting as well as board-less games.

  • Patent number: 7645587
    Abstract: The present invention provides novel, isolated, tumor-associated antigens, and methods for identifying such antigens in a biological sample, and of screening for the presence of such an antigen in a biological specimen, wherein the tumor antigen identified reacts with serum from a subject treated with a vaccine comprising a cytokine and proliferation-incompetent tumor cells which express the tumor-associated antigen. Also provided are kits for carrying out the methods of the invention.

  • Publication number: 20070033354
    Abstract: Each of a plurality of data items is stored in a table data structure. A row identifier and column identifier are associated with each respective data item, and each respective item is stored at a logical location in the table data structure specified by its row identifier and column identifier. A plurality of data items is stored in a cell of the table data structure, and a timestamp is associated with each of the plurality of data items stored in the cell. Each of the data items stored in the cell has the same row identifier, the same column identifier, and a distinct timestamp. In some embodiments, each row identifier is a string of arbitrary length and arbitrary value. Similarly, in some embodiments each column identifier is a string of arbitrary length and arbitrary value.

  • Patent number: 4035774
    Abstract: An electroluminescent memory and display device which may be switched from a first stable state to a second stable state in response to a relatively low switching voltage, and which may be maintained in said second stable state by a relatively low alternating sustain voltage. Basically, the solid state arrangement comprises a photoconductive layer separating first and second electroluminescent layers. The first electroluminescent layer is fabricated from an electroluminescent material having an emission band within the range of the excitation band of the photoconductive material of the interposing photoconductive layer. The second electroluminescent layer is fabricated from an electroluminescent material having an emission band outside of the range of the excitation band of the photoconductive material of the interposing photoconductive layer. Typically, the electroluminescent material of the second electroluminescent layer has an emission band in the visible range suitable for display purposes.
