  • Patent number: 7106802
    Abstract: Apparatus, and an associated method, for facilitating communication of data upon a communication channel which exhibits fading. Orthogonal transmit diversity techniques and trellis-coded modulation techniques are utilized to form a signal permitting the communication of data at high data rates while maintaining spectral efficiency, good error rate performance, without excessive computational complexity. The apparatus and associated method is advantageously implemented in a WLAN (Wireless Local Area Network) constructed pursuant to the IEEE 802.11 standard.

  • Patent number: 6924950
    Abstract: Apparatus, and an associated method, for facilitating viewing of a display indicia displayed upon a user display of a portable communication device, such as a cellular mobile station. An optical lens that exhibits a selected magnification level is positioned to overlay the user display. A mounting arm engages with the optical lens and with the portable communication device to affix the optical lens so that when the user of the communication device views the user display, the display indicia displayed thereon is magnified by the optical lens.

  • Patent number: 6817947
    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.

  • Patent number: RE39164
    Abstract: A method and system for transmitting packet data over a cellular telecommunications network is presented. A novel medium access control (MAC) logical layer is implemented between a service option layer and multiplex sublayer. The MAC layer handles the multiple accesses of packet users over selected dedicated traffic channels. The MAC layer provides a multiple access control function for packet data users only. Users requiring only circuit switched services (voice calls) are not serviced through the MAC layer multiple access control function. If a user has simultaneous circuit switched and packet data services operating, the MAC layer multiple access control function handles the packet data services, while the circuit switched services are handled simultaneously by bypassing the MAC layer multiple access control function.
