One aspect of the present invention is a method for the wireless transmission of information from one or more antennas to one or more separate users. The method comprises processing information to produce transmission vectors that minimize simultaneous interference between separate user channels and adjusting the radiation patterns to minimize total system radiation power for users specified capacities. In another aspect, the present invention includes apparatus and methods for providing multiple users of a network with information in such a manner that only the user that the signals are intended for receives the information.

Flexible transport system including support for bilateral user access

Public wireless communications will increasingly extend into wireless LAN (WLAN) environments in order to meet the ubiquitous access, high data rate, and local services demands of future Internet appliances. By relying on IP-level services mechanisms, the Public Access Mobility LAN (PAMLAN) can simultaneously support different air interfaces, franchises for multiple services providers, and a multi-segment LAN environment including handoffs. The PAMLAN supports virtual operator LANs representing different network services providers, authorization and accounting mechanism, support of multiple air interfaces, and local IP mobility. A router associated with each base station realizes this highly distributed IP networking environment, and a QoS-enabled switched Ethernet core supports virtual networks and QoS services.

Hierarchical hybrid optical networking is based on balancing cost and performance of optical networks by providing transparent (optical) switching of subsets of wavelengths in addition to opaque (electrical) switching of individual light paths. Effective use of wavelength-subset switching requires aggregating and deaggregating wavelength subsets in a simple, cost-effective manner. Non-uniform wavebands are introduced and analyzed their performance advantage as compared with uniform wavebands. Also proposed are several architectural options for a hierarchical hybrid optical cross-connect system that combines non-uniform wavebands and improved utilization of OEO ports.

A store-and-forward architecture which stores and distributes information programs to subscribers on demand includes: information warehouses which archive information programs from multiple service vendors and dispense information programs in segments to central offices in high speed bursts; central offices which manages subscriber's request for service and buffers segments of information programs for delivery to subscribers in real-time under the subscriber's interactive control; and customer premises equipment where a subscriber's requests and control signals for interactive play-out of information program are generated and information programs are received for the subscriber's use.

Communications architecture and method for distributing information

A store-and-forward architecture which stores and distributes information programs to subscribers includes: information warehouses which archive information programs and dispense information programs in segments to central offices in bursts; central offices which manage subscriber's requests for service and buffer segments of information programs for delivery to subscribers in real-time under the subscriber's interactive control; and customer premises equipment. The central offices employ CO buffers, and each CO buffer includes: processors, for administering internal buffer operations and processing subscribers requests based upon the service presentation script and a program presentation map; interfaces for providing external access; busses for internal transport; buffer storage for storing segments of information programs; and memory storage for storing the script and map.

A speaker verification and voice command system utilizing speech templates stored in an integrated circuit card is disclosed. To verify the user's identity, a comparison is made between a plurality of reference speech templates stored in the user's integrated circuit card and a test template formed from a word or words spoken by the user.

Speaker verification system using integrated circuit cards

There is disclosed a protection system for intelligent cards. Each card has stored in it a code which is the encryption of a concatenation of a user secret password and a common reference text. The encryption is derived by an initialization terminal which uses the private key associated with the public key of a public-key cryptosystem key pair. Each transaction terminal with which a card is used decrypts the stored code in accordance with the public key. A transaction is effected only if the stored code decrypts into the user password which is inputted on a keyboard and the common reference text.
