  • Publication number: 20040192366
    Abstract: The present invention discloses a method of playing an instant game on a wireless network terminal device by installing a network connection software in a wireless network terminal device, so that the wireless network terminal device can use the network connection software to connect to a network and let it be allocated to a network address and defined as a game host in order to create and play an instant game without going through the traditional network server and the network address of the network server.

  • Patent number: 6304364
    Abstract: Electromagnetic radiation valves are provided. In one system, a transparent, elastomeric article is provided having a contoured surface including protrusions and intervening indentations. The contoured surface is placed adjacent a transparent plate and a void pattern defined by indentations of the contoured surface is filled with an opaque fluid. The protrusions decrease in cross-sectional area in the direction in which they extend away from the bulk of the elastomeric article, thus compression of the elastomeric protrusions against the transparent plate results in an increase in surface area in elastomeric protrusions against the transparent plate due to deformation of the protrusions, and the opaque fluid is displaced from the voids. Increased transmission of the electromagnetic radiation results. In another system, a similar elastomeric article includes an array of corner cubes that are totally internally reflective of the electromagnetic radiation.

  • Patent number: 6187260
    Abstract: A process for making composite materials, namely reinforced Al-metal matrix composites based on either: (I) Al—W intermetallic phase and Al2O3 ceramic whiskers, or (II) Al—Mo intermetallic phase and Al2O3 ceramic whiskers. This process involves the oxidation of aluminum using tungsten oxide in powder form for product I, and that of aluminum and molybdenum oxide in powder form for product II. Product I contains an Al—W intermetallic phase, some sapphire whiskers, and a continuous Al-metal matrix. Product II contains an Al—Mo intermetallic phase, sapphire whiskers, and a continuous Al-metal matrix. The alumina whiskers are formed as a result of two reactions. They are: (i) the oxidation between the pre-mixed Al and the oxide, and (ii) the oxidation of Al with the atmospheric environment in the presence of the oxide, which acts as a catalytic agent for the reaction. These newly invented products are hard, strong and light.
