Abstract: Systems and methods for providing telephone service to transient or inaccessible customers include a stationary cellular telephone that operates like a land-line telephone in that its use is restricted to a single geographic area, such a house address. The stationary cellular telephone can only handoff between cell sites that are associated with the geographic area. The stationary cellular telephone can place calls using only cell sites in a list of permissible cell sites that is maintained at the network level. The stationary cellular telephone is activated by sending customer, device, and/or location identifiers to an activation center via a telephone call. The activation center validates service, and downloads the list of permissible cell sites to the stationary cellular telephone. Dynamic rates provide opportunities for further reduction in the cost of service, with real-time notification of capacity based pricing, and service levels that vary according to network capacity.

Abstract: Systems and methods for controlling traffic on a communications network include dynamic and flexible control plans that enable service providers to control or influence customer access to communications facilities. Communications facilities are monitored to identify network elements, such as cell sites, that are overloaded. When the traffic intensity on a particular facility exceeds a predetermined level, either active or passive control is imposed on subscribers that are in the geographic area of the facility. Active control involves blocking, delaying or disrupting subscriber calls during the critical time period. Passive control involves providing cost incentives or disincentives during low or peak periods of traffic intensity. Customers are notified of the commencement and/or termination of active or passive control preferably via SMS.

Abstract: A method and apparatus for use in air-traffic control are described for maintaining substantial registration alignment between radar video signals and associated computer generated data on a television monitor. It is a requirement of the monitor display that the radar video, such as raw radar, map video, etc., be displayed with a long time constant to show the history of the radar trails. Simultaneously, the associated computer generated data, such as vectors, alpha-numerics, etc., must be displayed properly registered with the radar video on the same monitor with a short time constant. This is necessary to avoid smearing, since the latter data moves on the monitor screen as the radar pattern changes. In accordance with the present invention, the radar and computer data are combined into a single cathode ray tube, photographed by a pair of vidicons having different time lag characteristics, and the images of the latter combined on a television monitor.
