Abstract: An organic light-emitting diode (OLED) device, comprises: a first electrode and a second transparent electrode having one or more organic layers formed there-between, at least one organic layer being light-emitting; and a contrast enhancement element formed on a side of the second transparent electrode opposite the organic layers, wherein the contrast enhancement element comprises a patterned reflective layer for reflecting emitted light and a corresponding light-absorbing layer for absorbing ambient light, wherein the reflective layer is located between the light-absorbing layer and the second transparent electrode and wherein the corresponding layers form one or more transparent openings through the reflective and light-absorbing layers so that light emitted by the light-emitting organic layer passes through the transparent openings.

Abstract: An SRAM device and a method of placing a portion of memory cells of an SRAM device in an active mode is provided. In one embodiment, the SRAM device includes a hierarchical grouping of memory cells of memory cells and biasing circuitry, coupled to the hierarchical grouping of memory cells, configured to bias a subset of the set based on a memory address associated therewith. In another embodiment, a method includes receiving a memory address associated with the hierarchical grouping of memory cells and biasing a subset of the hierarchical grouping of memory cells based on the memory address.

Abstract: A multi-player video game server includes a player control interface, a video interface, and a game engine. The player interface couples the game server to a network and can receive game control data over the network from multiple players. Each player has a game control device at which game control data can be input. The video interface couples the game server to a video transmission network and transmits game display video over the video transmission network. The game engine is coupled to the player interface and the video interface and includes a processor and a memory. The memory stores multi-player video game instructions that configure the processor to process game control data and render the game display video that is then provided to the video interface for transmission over a video network. A multi-player video gaming method includes receiving a number of player input data connections at a game server.

Abstract: A time sharing method and apparatus for frequency reuse in cellular communication systems. Frequency reuse is enhanced by synchronizing cell transmit/receive base stations in a cellular system to a common time base, and then sharing the available frequencies via allocated time slots. Cells using the same frequency that may interfere with each other are activated only during selected time intervals while same-frequency cells nearby are deactivated. The deactivated cells are then in turn activated while previously activated same-frequency cells nearby are deactivated. The frequency time slots may be of equal length, or longer time slots may be allocated to cells having higher usage rates, as determined in any of a number of ways. The time slots may be mutually exclusive, or may overlap. The time sharing technique of the present invention allows design of cell systems with many reuse patterns.
