A method and a system for establishing a self-owned and self-managed network-based voice communication solution (VCS) for supporting business transactions and commerce applications over the communications network(s) including the Internet and PSTN. The voice communication solution is requested by a merchant or business entity at a computer connected to the Internet by providing (i) information needed for approval and (ii) system configuration for accepting the solution. Through a friendly interactive process with a web server and a solution server, the necessary software for voice communication is downloaded to a merchant's designated computer host, turning it to be a VCS server. Upon activation, the VCS server can support voice over IP (VOIP) communication and connect an incoming call to a telephone via PSTN or a PBX network. The VCS server can receive a VOIP call from anyone at anyplace via an Internet connected voice enabled computer. The caller launches a call agent via the merchant's web page(s) or via a computer desktop interface or via a VOIP phone interface to reach the privately held voice communication server.

Methods for operating multimedia computers to provide e-commerce voice communication capability directly between any computer connected to a computer network such as the Internet and any telephone device connected to the PSTN are disclosed. A simple click and call method is enabled by employing call interface software and the standard communication protocol over the network. The e-commerce voice communication system (EVCS) represented by an e-commerce voice communication symbol on a web page which, upon clicking, launches the call interface program, initiates a real-time communication channel between the client computer and the receiving computer, dials the desired telephone number via a voice modem. The EVCS method receives packets of voice data from the client computer, reassembles the packets of voice data into a stream of digital voice data, converts it to a stream of analog voice data, outputs the analog voice data to the voice modem, and outputs the analog voice data from the voice modem to the telephone line and vice versa from the telephone line to the client computer.

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.

A flat storage cathode ray tube with enhanced brightness is described. A mesh collector and a dielectric storage site array form an integral part of a silicon wafer. The silicon wafer includes thereon an addressable array of field effect transistors having a field effect transistor associated with a dielectric storage site in the storage site array for controlling a writing of the dielectric storage site. The addressable array of transistors works in cooperation with a flooding electron gun to effect selective writing of the storage site array. The enhanced brightness cathode ray tube may be adapted for use in a projection display.
