Abstract: A satellite communications system comprises multiple satellites (e.g., a combination of LEO/MEO/GEO satellites). Multiple satellite gateways communicate over channels of the satellites with remote mobile user terminals. The mobile user terminals communicate with the satellite gateways via associated satellite terminals that interface with the satellites, or directly with the satellites. Each mobile user terminal of a first group communicates with a satellite gateway, over satellite channels, via an associated satellite terminal. Each mobile user terminal of a second group (e.g., in a remote rural area) communicates with a satellite gateway directly over satellite channels. The mobile user terminals of the first communicate with the satellite terminals locally via S-band. The mobile user terminals of the second group communicate directly over the satellite channels via Ku band or Ka Band. Each of the satellite gateways communicates over satellite channels via Ka band, Ku band, V-band or L-band.

Abstract: A system and method are provided for hybrid electric internal combustion engine applications. A motor-generator, a narrow switchable coupling and a torque transfer unit are arranged in the constrained environment at the front of an engine. The motor-generator is preferably laterally offset from the switchable coupling, which is co-axially-arranged with the engine crankshaft. The switchable coupling is an integrated unit in which a crankshaft vibration damper, an engine accessory drive pulley and a disengageable clutch overlap such that the axial depth of the clutch-pulley-damper unit is nearly the same as a conventional belt drive pulley and engine damper. The front end motor-generator system includes an electrical energy store that receives electrical energy generated when the coupling is engaged.

Abstract: Systems and methods provide bandwidth management on the inroute of a satellite network. Inroute group managers (IGMs) monitor bandwidth usage in each terminal group (TG) under each of the IGMs, and report this bandwidth usage to a bandwidth manager. Upon receipt of the reported bandwidth usage from each of the IGMs, the bandwidth manager compares the bandwidth usage and minimum/maximum throughput rates associated with each TG. The bandwidth manager calculates scaling factors that it transmits to each of the IGMs to allow the IGMs to allocate bandwidth accordingly.
