Abstract:
A ground transceiver (16, 16A, 16B, 16C, 16D) is configured to communicate with a satellite transceiver (14). The satellite transceiver (14) is configured to receive concurrently a plurality of messages (20) at substantially the same carrier frequency from a plurality of ground transceivers (16A, 16B, 16C, 16D). The ground transceiver includes a receiver configured to receive a ranking threshold from the satellite transceiver (14); and a transmitter configured to determine if a message (20) is authorized to be transmitted based on a comparison of the ranking threshold and a transceiver ranking of the ground transceiver (16, 16A, 16B, 16C, 16D).

Abstract:
The present invention generally relates to the transmission of GPS reference information, and more particularly, to transmission of GPS ephemeris information for mobile applications. A Telemetry word data is provided by and/or transmitted by a non-cellular, land based network and received by a receiver (316, 318, 320, 322). A location signal is computed by a processor and transmitted to the GPS receiver. An accumulator accumulates that data and stores it in a data base (216). The unit may be connected to a Public Safety Answering Point (214). Also, the present invention provides a method to assist the GPS in mobile applications where the user does not necessarily have a cellular phone. The present invention discloses a method of transmitting ephemeris data to assist the GPS receiver without relying on the cellular telephone network.

Abstract:
A method (100) and apparatus (60) provide dynamic content rating for digital transmissions (20) of media programs. Rather than one rating or a set of ratings be associated with an entire program or broadcast channel, content rating data relates to specific segments (44,46,52) of a program. A user of a media receiving device (66) presets rating criteria (104) relating to a level or type of content to be blocked. The preset criteria are then used to selectively block (112) presentation of those segments of content of a media program that fall outside the acceptable rating criteria. A timed length or display area (52) segment of audio, video, text, graphics, or data may be dynamically blocked based on a comparison (110) of the content rating associated with the segment and the user's preset rating criteria.
