Abstract: An electromagnetic pulse (EMP) resistant telecommunications system includes core components mounted within and shielded by a Faraday cage. The components include a data source or storage device. An ethernet switch selectively connects the data source or storage device to a primary satellite router and a post-EMP satellite router. Telecommunications signals are output from and input to the core components via low noise blocks (LNBs) and block upconverters (BUCs). A method of resisting EMP interference for a telecommunications system includes the steps of enclosing and shielding core components in a Faraday cage and providing output via LNBs and BUCs to an antenna subsystem. The antenna subsystem can include one or more antenna elements with configurations chosen from the group comprising: parabolic dish; array; unidirectional; and omnidirectional.

Abstract: An apparatus for removing or installing a turbine blade from a turbine of a turbomachine is disclosed. The apparatus can include: an operative head configured to engage an axial sidewall of a turbine blade base. An actuator is configured to move the operative head to selectively engage the axial sidewall of the turbine blade base and impart an axial force against the turbine blade base to remove or install the turbine blade. A support gantry is configured to position the actuator substantially vertically above the turbine blade in position in the turbomachine. Among other advantages, the support gantry allows adjustment of the apparatus for different turbines, and use of the head on more than one stage of any given turbine.

Abstract: A multi-band signal communications system includes a hub station communicating with multiple remote stations. The system reduces or eliminates the effects of precipitation, airborne pollutants, dust and debris. Signals can comprise digital or analog signals, which can be encrypted. The system can utilize binary digital or quantum computing technologies. The system can utilize frequency-hopping and satellite-hopping routines for security. System components can be fabricated from silicone-based semiconductors and graphene. System functions can be implemented with hardware, firmware and software. The communications system and method can be implemented with fiber-optic cables, laser transmissions and microwave-frequency media.

Abstract: An electromagnetic pulse (EMP) resistant telecommunications (telecom) system includes core components mounted within and shielded by a Faraday cage. The components include a data source or storage device. An ethernet switch selectively connects the data source or storage device to a primary satellite router and a post-EMP satellite router.

The antenna subsystem can include one or more antenna elements with configurations chosen from the group comprising: parabolic dish; array; unidirectional; and omnidirectional. The EMP-resistant telecom can optionally be combined with a signal regenerating subsystem and used with a signal regenerating method.

Abstract: A hybrid satellite communication system in which a hub station transmits signals to remote stations through a satellite at a relatively low frequency unaffected by weather effects and in which the remote stations transmit signals to the hub station at a relatively higher frequency which enables use of more economical equipment at remote stations. The hub station senses signal quality or strength received from each remote station and transmits power control signals to remote stations with poor signal strengths to cause such remote stations to increase output power to overcome weather effects. The power control signals are transmitted on the lower frequency to prevent the power control signals from being masked by the weather effects. A communications satellite can the either geostationary or low Earth orbit (LEO). Data can also be transmitted on the relatively low frequency. The communication system can utilize antennae with dish, array and other suitable configurations.
