Abstract:
The invention relates to a system and method for receiving at a receiving location data signals for range of said television and/or radio channels, and distributing selected data signals via a distribution network to a plurality of user locations connected thereto, the said selection of data signals made dependent upon user selections independently made at the said user locations to receive data for one or more channels. The data signals are translated via data processing means components to provide the data signals in a plurality of predetermined bandwidths and then data signals for a subset of channels are provided in a digital channel stacked format and from which there are provided one or more outputs to which the apparatus at the user locations are connected in order to allow data signals for the subset of said television and/or radio channels to be distributed to the apparatus at the user locations as required. In one embodiment the data signals are carried on the distribution network in an optical format for at least part of the distribution path.

Abstract:
Systems and methods are described that use the downlink and uplink frequency bands of the fixed satellite service (FSS) and direct broadcast service (DBS) systems to provide broadband access to aerial platforms including aircraft, drones, and unmanned aerial vehicles (UAVs) such as balloons. The secondary service aerial platform transmitters are configured to avoid interference into the primary satellite service receivers. The aerial platform may be able to detect and connect to the cell site with the strongest signal. The aerial platform may be able to handoff from one cell site to another. Systems and methods are described that provide broadband access to ground terminal via aerial platforms such as drones and UAVs such as balloons.
Abstract:
Systems and methods for distributing digital satellite broadcast programs over multicast Internet Protocol (IP) networks are provided. A satellite receiver gateway receives a signal from a digital satellite broadcast and generates service information multicast packets that are transmitted over a multicast IP network. A device receives the service information multicast packets and generates a channel list or electronic program guide for a user. When a user selects a service from the channel list or electronic program guide the device sends a service request for the service towards the satellite receiver gateway. Either the satellite receiver gateway or a switch within the multicast IP network can then transmit the service in multicast IP packets to the requesting device.
Abstract:
A satellite reception assembly that provides satellite television and/or radio service to a customer premises may comprise a wireless interface via which it can communicate with other satellite reception assemblies. Wireless connections between satellite reception assemblies may be utilized for providing satellite content between different satellite customer premises. Wireless connections between satellite reception assemblies may be utilized for offloading traffic from other network connections.
Abstract:
A mobile content distribution system (100) in an airplane, a train, or a bus is capable of receiving wireless broadcast channels from a wireless service provider. The system offers a user purchase of wireless services including one or more broadcast channels provided by the wireless service provider, receives information indicative of a route from an originating location to a destination location, and determines if the content distribution system is authorized to receive services from the wireless service provider according to the information; and if the content distribution system is not authorized to receive services from the wireless service provider according to the information, the system provide a refund to the user. If the system is within an authorized area, the system determines if the system is authorized to provide full service from the wireless service provider according to the information and if the system is not authorized to provide full service, the system provides a partial refund to the user.

A fluid sensor comprises a sensor housing (12), a sensor package (14), an actuator (16) and a switch (18). The sensor package (14) is disposed within the sensor housing (12) and includes first and second screens and at least one sensing membrane. The sensing membrane is disposed between the first and second screens (36) and is adapted to expand when exposed to a predetermined quantity of a first predetermined fluid. The actuator (16) is disposed proximate the sensor package (14) within the sensor housing (12) and moveable between a first position and a second position through an intermediate position. The switch (18) is disposed proximate the actuator (16) and is operable between closed and open positions. When the actuator (16) is in the second position at least a portion of the actuator (16) depresses the switch (18) to control an- electrical, circuit connected therewith.
