A communication system has a plurality of nodes that perform encrypted communication via a LAN, each using an identical common cipher key. The common cipher key is replaced at fixed or irregular intervals, by being transmitted from a main node in a broadcast mode via the LAN to respective secondary nodes that are to share the key. When the key is successfully received by a secondary node, it returns a confirmation signal. The system can be configured such that a notification list of secondary nodes for which key acquisition has been confirmed is transmitted to all of the secondary nodes.

A networked data processor maintains a database of information concerning potential evidence from litigants in legal proceedings supporting stipulated discovery agreements, and requiring meet-and-confer sessions prior to seeking court supervision. Individual or adverse parties can participate. Sources include data custodians, file repositories, electronic data, witnesses, etc. Managers and employees are polled to populate a database defining the litigant's organization and evidence. The evidence may be sequestered, copied and processed, e.g., filtered for confidentiality or privilege, analyzed as to format, and queried to assess the volume of data that would be responsive under alternative discovery specifications. Cost and time are assessed under alternative specifications and reports are provided for use in negotiating a discovery plan. A stipulated discovery plan may result, or if not, a meet-and-confer session is electronically managed in a multi-user teleconference. A report of stipulated and disputed points and associated arguments can be presented to the court.

A dual-arm coupling quadrature mode coupler with high cross polarization discrimination comprises a chamfer matching mode T, a public waveguide, a pubic waveguide transformer, two coupled arms, a waveguide receiving transformer, a low-pass filter, a waveguide transmitting transformer and absorbing load. Excitation of high order modes in the public waveguide is reduced greatly by utilizing symmetrical structures of two coupled arms, and dual-arm feed is realized on the quadrature mode coupler by adopting the chamfer matching mode T, thereby effectively guaranteeing signal division at a coupling port of the quadrature mode coupler, enabling the quadrature mode coupler to achieve excellent uniform amplitude characteristics and fine port isolation, reducing discontinuity, further reducing excitation to the high order modes as few as possible, obviously increasing the cross polarization discrimination, and then successfully resolving problems that a satellite communication antenna achieves high cross polarization discrimination at a separation band. In addition, the dual-arm coupling quadrature mode coupler is simple in implementing mode, low in processing cost and high in cost performance ratio and can be widely applied to various frequency ranges.

A system can control whether a recipient of an electronic message (e.g., a text message, a multimedia message, an e-mail message, etc.) with a forwarding-restricted attachment is permitted to forward the attachment to third parties can be implemented on the network without specialized hardware or software for the client devices. The sender of a text message may limit the downstream distribution of that text message through text message forwarding by associating a forwarding restriction flag with the message.

A method and apparatus delays users from accessing a service via the world wide web in an orderly manner without maintaining a queue. When a user requests the service, if the service is busy, a web server does not allow access to the service: instead it configures the user's web browser via a script or applet to periodically retry requesting the service. A timestamp designating a time the user requested the service or other similar time is provided to the user and a count of timestamps issued in different periods are maintained by the web server. The web server periodically determines a cutoff timestamp corresponding to an available capacity of the apparatus using the count of timestamps it maintains. When the user retries requesting the service, the browser provides to the web server the timestamp it received from the server. If the timestamp provided is less than or equal to the cutoff timestamp, the user is allowed access to the service, otherwise, the users browser is instructed to retry at a specified interval.
